"Gladiator" Tomb Discovered In Rome


From The CBS:

Archaeologists Uncover Mausoleum Belonging To Roman General Who Inspired Oscar-Winning Epic

(CBS/AP) The tomb of a rich Roman general, believed to be the inspiration for the main character of the Oscar-winning movie "Gladiator," has been found on the outskirts of Rome.

Ongoing construction work along the northbound Via Flaminia uncovered the remains of a mausoleum that archaeologists believe to be at least fifteen yards long.

An inscription among the remains gives reason to believe that the tomb belongs to a patrician known as Marcus Nonius Macrinus, a proconsul who achieved major victories for Marcus Aurelius, emperor from 161 AD until his death in 180 AD.

Macrinus, a favorite of the emperor, is thought to have been the inspiration for the writers of the 2000 Ridley Scott film when imagining the character played by Russell Crowe in the award-winning epic.

Senior archaeologist Daniela Rossi of Rome's Superintendency for Archaeology said inscriptions indicate the tomb belonged to Macrinus, a well-known figure from a family from Brescia in northern Italy. Rossi said Macrinus had a unique resume: "Police commissioner, magistrate, proconsul of Asia, and committees of the Emperor. He was very close to Marcus Aurelius who wanted him in the war against the Marcomanni," a Germanic tribe.

The World's Top 10 Worst Pollution Problems


From Scientific American:

From the residue of mining to untreated sewage, the world is grappling with a host of environmental problems.

The "I Trust My Legs" gold mine in Ghana is a local affair, where miners shift silt from rudimentary pits and then combine it with mercury. The element (a toxic metal that can cause brain damage) captures all the gold in the dirt and then, when the mixture is heated, dissipates into the air, leaving just gold bits behind. Unfortunately, in what is known as artisanal mining, the mercury also enters the lungs of miners, their families and others nearby. The United Nations Industrial Development Organization (UNIDO) estimates that some 15 million miners, their families and neighbors (including 4.5 million women and 600,000 children) are affected by the fumes, which are known to cause brain damage and even death.

Such gold mining is just one of world's most pressing global pollution problems, according to the Blacksmith Institute, an environmental health group based in New York City. Among the others: air pollution in homes from cooking, industrial smog in cities, untreated sewage, metal smelting and the recycling of lead (which causes brain damage) from old batteries.

Science On The 'Fringe'

From Live Science:

FRINGE takes viewers on a wild ride using sciences that traditionally lie on the "fringe" of mainstream science, such as mind control or teleportation. But with so much research being done in these fields, many of the show’s ideas are actually ripped from science magazines and journals.

"We start by finding ideas right out of the headlines from a science magazine or the announcement for new research grant and we think, 'what is the next step or how can we push the boundaries?'" said Whitman. "For example, in episode three one of the characters was receiving messages in his brain telepathically and the Monday before the show aired, we saw an article on the CNN website that explained how the U.S. Army was developing a helmet that uses brain waves to help soldiers talk to each other."

Whitman and Chiappetta are "media consultants," not scientists, and while they’ve been advisors on several TV shows, they note their expertise comes from curiosity and researching science journals and the popular press, not formal training. Chiappetta has a law degree from the University of Texas, and Whitman has his PhD in economics from New York University.

Brain Starts To Slow Down At 40

From The Telegraph:

Life does not begin at 40 - it just slows down.

According to the latest research, our brain is fastest at 39 and afterwards, it declines "at an accelerating rate." That means that reactions also slow, claim the researchers.

The loss of a fatty skin that coats the nerve cells, called neurons, during middle age causes the slowdown, experts say.

The coating acts as insulation, similar to the plastic covering on an electrical cable, and allows for fast bursts of signals around the body and brain.

When the sheath deteriorates, signals passing along the neurons in the brain slow down. This means reaction times in the body are slower too.

Scientists at the University of California, Los Angeles, say that after 40 the body "loses the battle" to repair the protective sheaths.

The finding was made after researchers tested how quickly men aged from 23 to 80 could tap their index fingers in ten seconds.

Pictured: Stunning Images Of Spiral Galaxy 50Million Light Years Away

Diffuse clouds made up from dust and complex organic molecules can be seen in the long-range images of NGC 7331 (Image from the Daily Mail)

From The Daily Mail Online:

It can usually only be seen as a faint fuzzy spot through the average telescope, but these stunning images show just how magnificent the spiral galaxy NGC 7331 can be.

The galaxy is around 50million light years away in the northern constellation, Pegasus, and is similar in size to our own 'Milky Way' galaxy.

The long-exposure photographs were taken with a LAICA camera (Large Area Imager) by the Calar Alto Observatory, based in southern Spain, who attached a camera to a 3.5m telescope to capture the impressive shots.

The outstanding spiral structure of NGC 7331 is seen shining behind a number of stars belonging to our galaxy the Milky Way, and in front of a rich background populated by an overwhelming variety of distant galaxies.

A thin haze of the ghostly, fuzzy and dusty nebulae known as galactic cirrus is visible. The diffuse clouds are made up from dust, complex organic molecules and gas.

NGC 7331 was discovered by the astronomer Wilhelm Herschel in 1784. The sharpness of the images are believed to represent the deepest view of the region to date.

Chinese Angry Over Microsoft Anti-Piracy Tool

From MSNBC/Reuters:

Program turns computer screen black if installed software fails validation

BEIJING - Chinese Internet users have expressed fury at Microsoft's launch of an anti-piracy tool targeting Chinese computer users to ensure they buy genuine software.

The "Windows Genuine Advantage" program, which turns the user's screen black if the installed software fails a validation test, is Microsoft's latest weapon in its war on piracy in China, where the vast majority of 200 million computer users are believed to be using counterfeit software, unwittingly or not.

"Why is Microsoft automatically connected with my computer? The computer is mine!" one angry blogger wrote on popular Chinese web portal Sina.com. "Microsoft has no right to control my hardware without my agreement."

Another blogger railed over the cost of authorized versions.

"If the price of genuine software was lower than the fake one, who would buy the fake one?" he wrote.

McGill Physicists Find A New State Of Matter In A 'Transistor'

From E! Science News:

McGill University researchers have discovered a new state of matter, a quasi-three- dimensional electron crystal, in a material very much like those used in the fabrication of modern transistors. This discovery could have momentous implications for the development of new electronic devices. Currently, the number of transistors that can be inexpensively crammed onto a single computer chip increases exponentially, doubling approximately every two years, a trend known as Moore's Law. But there are limits, experts say. As chips get smaller and smaller, scientists expect that the bizarre laws and behaviours of quantum physics will take over, making ever-smaller chips impossible.

This discovery, and other similar efforts, could help the electronics industry once traditional manufacturing techniques approach these quantum limits over the next decade or so, the researchers said. Working with one of the purest semiconductor materials ever made, they discovered the quasi-three-dimensional electron crystal in a device cooled at ultra-low temperatures roughly 100 times colder than intergalactic space. The material was then exposed to the most powerful continuous magnetic fields generated on Earth. Their results were published in the October issue of the journal Nature Physics.

Space Programs Poised for Major Expansion in Asia

From National Defense Magazine:

SAPPORO, Japan — Japan’s government is about to kick off a major expansion of the nation’s space programs. The goal is to broaden the scope of space research from traditional areas such as exploration into new military and commercial applications.

The intent is to boost the country’s space industry and, over time, become less dependent on foreign suppliers such as the United States.

“There was a huge inferiority complex for the Japanese industry, that we needed to catch up with the top-level, state-of-the-art technology,” says Hokkaido University associate professor Kazuto Suzuki.

These goals would have been unrealistic until Japan’s legislature passed a law that for the first time creates a dedicated space bureau — run by a controversial politician, Seiko Noda.

“They knew they had to change their space law and their space organization because they were not structured and organized in order to compete in the 21st century,” says Vincent Sabathier, senior fellow and director of space initiatives at the Center for Strategic and International Studies in Washington.

The Japanese government beginning in the 1970s invested 4 trillion yen into research and development projects, including satellites, rockets, launchers, exploration spacecraft, and most recently, Kibo, the experimental module that was installed aboard the International Space Station this summer.

Do Five Simple Things A Day To Stay Sane, Say Scientists

From Times Online:

Simple activities such as gardening or mending a bicycle can protect mental health and help people to lead more fulfilled and productive lives, a panel of scientists has found.

A “five-a-day” programme of social and personal activities can improve mental wellbeing, much as eating fruit and vegetables enhances physical health, according to Foresight, the government think-tank. Its Mental Capital and Wellbeing report, which was compiled by more than 400 scientists, proposes a campaign modelled on the nutrition initiative, to encourage behaviour that will make people feel better about themselves.

People should try to connect with others, to be active, to take notice of their surroundings, to keep learning and to give to their neighbours and communities, the document says.

Its advice to “take notice” includes suggestions such as “catch sight of the beautiful” and “savour the moment, whether walking to work, eating lunch or talking to friends”. Examples of learning include mending a bike or trying to play a musical instrument.

California Is Due for a Katrina-Style Disaster

(Click to Enlarge)
Image from Wired Science

From Wired Science:

When the next big earthquake hits the San Francisco Bay Area, it will be a catastrophe of Hurricane Katrina proportions. Hundreds, perhaps thousands of people will die, and hundreds of thousands will become homeless. Economic losses will be on the order of $200 billion, the vast majority of it uninsured. Outside help will be desperately needed, but difficult to coordinate and execute.

And just as before Hurricane Katrina, scientists have been sounding the alarm, warning that the disaster is inevitable. It's not a matter of if, but when the "Big One" will strike.

"The reality is that we could have a large earthquake at any time," said geologist David Schwartz of the U.S. Geological Survey.

The Bay Area is lined with faults capable of delivering a knock-out blow. But one in particular is poised to rupture sooner than later. Geologists have determined that the average time between major earthquakes on the Hayward fault is 140 years. The last big one was October 21, 140 years ago.

Invention: Hurricane Pacifier

Releasing smoke particles into the lower reaches of a hurricane can shift energy to its periphery and reduce the severity of the storm, say the authors of a new patent application (Image: WIPO)

From New Scientist Tech:

Interest in hurricane mitigation has peaked since Hurricane Katrina devastated New Orleans in 2005, and any means of limiting the damage wrought by these huge storms would be welcomed by governments and vulnerable populations alike.

Now an Israeli team says it has developed a way to take the sting out of the storms. Their new patent application says seeding hurricanes with smoke particles could lower wind speeds enough to mitigate their destructive potential.

A hurricane's destructive potential is proportionally related to the strongest winds inside it, and only a small reduction in wind speed is needed to dramatically reduce the damage it causes.

Hurricanes derive their immense power from warm waters on the surface of the sea. As the water evaporates, it rises into the hurricane and eventually condenses and falls as rain, releasing its latent heat energy as it does so – a process known as "heat cycling".

Daniel Rosenfeld and colleagues at the Hebrew University of Jerusalem say injecting smoke into the lower parts of a hurricane causes water vapour to condense at a lower altitude than usual, and form droplets that are too small to fall as rain.

Sizing Up The Earth

"Earth" is the largest atlas ever produced and weighs over 30 kilos. (Image from CNN)

From CNN:


LONDON, England (CNN) -- It is being billed as the ultimate book about the world and it is something of a landmark in its own right. "Earth" -- the biggest atlas ever to be published -- promises to be a luxurious benchmark in cartography.

Created by Millennium House, "Earth" -- complete with a clam shell case -- measures 610 x 469 millimeters and weighs in at over 30 kilos.

The price is pretty hefty too. The leather bound, gilt-edged book will set you back around $3500.

Its existence owns much, if not all, to the perseverance of Australian businessman Gordon Cheers who has been dreaming of creating such a book for over 20 years.

Cheers, who has spent much of his working life at some of the world's major publishing houses, couldn't convince his various employers to take the project on. Penguin said no. So did Random House.

Undeterred, Cheers decided to start his own company, Millennium House, which produces a wide range of high quality reference books.

Less Ice In Arctic Ocean 6000-7000 Years Ago
-- Science Daily


ScienceDaily (Oct. 20, 2008) — Recent mapping of a number of raised beach ridges on the north coast of Greenland suggests that the ice cover in the Arctic Ocean was greatly reduced some 6000-7000 years ago. The Arctic Ocean may have been periodically ice free.

”The climate in the northern regions has never been milder since the last Ice Age than it was about 6000-7000 years ago. We still don’t know whether the Arctic Ocean was completely ice free, but there was more open water in the area north of Greenland than there is today,” says Astrid LysÃ¥, a geologist and researcher at the Geological Survey of Norway (NGU).

Form Cosmic Log/MSNBC:

The current round of financial uncertainty is coming at just the wrong time for America's largest and smallest fusion research programs.

In its simplest form, nuclear fusion involves combining the nuclei of hydrogen atoms to produce helium atoms, plus a smidgen of energy. It's the energy reaction that powers the sun as well as hydrogen bombs. For decades, scientists have been trying to tame the process to produce what could be an abundant, high-yield power source that is less environmentally problematic than nuclear fission.

Federal funding currently backs three strategies for fusion power:

Lethal Build-Up Of Ozone Poses Threat To UK

(Photo from NASA)

From The Guardian:

Scientists call for global measures amid warnings that the gas damages health and the environment

Britain is ignoring the dangers posed by one of the world's worst air pollutants: ozone. Researchers say that levels of the gas - a powerful contributor to global warming and the cause of hundreds of deaths a year from respiratory illnesses - are rising at an alarming rate.

They have also warned that measures to curtail the gas are failing. As a result, ozone-related deaths, of which there are about 1,500 a year in the UK, could rise by 50 per cent over the next decade. Stronger international treaties need to be set up to counter the threat, they insist.

'A lot more interest needs to be taken in ozone - not only as a cause of global warming but as an immediate threat to human health and to the environment,' said Professor Piers Foster of Leeds University, an author of the most recent report from the Intergovernmental Panel on Climate Change. 'It could have a significant impact on the planet.'

From Scientific American:

The waters of the Jersey Shore may soon become home to the nation's first deepwater wind turbines. New Jersey officials recently announced the state would help fund an initiative by Garden State Offshore Energy to build a 350-megawatt wind farm 16 miles (26 kilometers) offshore. The state wants by 2020 many more of these parks, at least 3,000 megawatts worth, or about 13 percent of the state's total electricity needs.

"This is probably the first of many ambitious goals to be set by states," says Greg Watson, a senior advisor on clean energy technology to the governor of Massachusetts. "Three thousand megawatts is significant. With that you're able to offset or even prevent fossil fuel plants from being built."

The federal government is about to open up to wind energy development vast swaths of deep ocean waters, and states and wind park developers are vying to be the first to seize the new frontier. Wind parks in these waters can generate more energy than nearshore and onshore sites, they don't ruin seascape views, and they don't interfere as much with other ocean activities.

'Western' Diet Increases Heart Attack Risk Globally

From E! Science News:

The typical Western diet — fried foods, salty snacks and meat — accounts for about 30 percent of heart attack risk across the world, according to a study of dietary patterns in 52 countries reported in Circulation: Journal of the American Heart Association. Researchers identified three dietary patterns in the world:

* Oriental: higher intake of tofu, soy and other sauces;
* Prudent: higher intake of fruits and vegetables; and
* Western: higher intake of fried foods, salty snacks, eggs and meat.

The Prudent diet was associated with a lower heart attack risk than the Oriental, researchers said.

"The objective of this study was to understand the modifiable risk factors of heart attacks at a global level," said Salim Yusuf, D.Phil., the study's senior author.

Previous studies have reached similar conclusions about the Prudent and Western diet in the United States and Europe. This study broadens those findings and identifies a unique dietary pattern that researchers labeled "Oriental" (because of a higher content of food items typical of an Oriental diet.) The dietary pattern recommended by the American Heart Association is similar to the Prudent diet described in this study.

Current Mass Extinction Spurs Major Study Of Which Plants To Save

From E! Science News:

The Earth is in the midst of the sixth mass extinction of both plants and animals, with nearly 50 percent of all species disappearing, scientists say. Because of the current crisis, biologists at UC Santa Barbara are working day and night to determine which species must be saved. Their international study of grassland ecosystems, with flowering plants, is published this week in the Proceedings of the National Academy of Sciences.

"The current extinction event is due to human activity, paving the planet, creating pollution, many of the things that we are doing today," said co-author Bradley J. Cardinale, assistant professor of ecology, evolution and marine biology (EEMB) at UC Santa Barbara. "The Earth might well lose half of its species in our lifetime. We want to know which ones deserve the highest priority for conservation."

He explained that the last mass extinction near the current level was 65 million years ago, called the Cretaceous Tertiary extinction event, and was probably the result of a meteor hitting the Earth. It is best known for the extinction of non-avian dinosaurs, but massive amounts of plant species became extinct at that time as well.

'Junk' DNA May Have Important Role In Gene Regulation

From Science Daily:

ScienceDaily (Oct. 20, 2008) — For about 15 years, scientists have known that certain "junk" DNA -- repetitive DNA segments previously thought to have no function -- could evolve into exons, which are the building blocks for protein-coding genes in higher organisms like animals and plants. Now, a University of Iowa study has found evidence that a significant number of exons created from junk DNA seem to play a role in gene regulation.

The findings, which increase understanding of how humans differ from other animals, including non-human primates, appear Oct. 17 in the open-access journal PLoS Genetics.

Nearly half of human DNA consists of repetitive DNA, including transposons, which can "transpose" or move around to different positions within the genome. A type of transposon called retrotransposons are transcribed into RNA and then reintegrated into the genomic DNA. The most common form of retrotransposons in the human genome are Alu elements, which have more than one million copies and occupy approximately 10 percent of the human genome.

Thirsty World: Desperate Quest For Water -- CNN

The following is an excerpt from "What Matters," the latest book by "Day in the Life" series creator David Elliot Cohen. For more information, see whatmattersonline.com

Water is the key to life. It is fundamental to all human activities. Water grows the food we eat, generates the energy that supports our modern economies and maintains the ecological services on which we all depend. Yet billions of people worldwide still lack access to the most basic human right: safe, clean, adequate water.

As you would expect, the vast majority of these people are among the poorest in the world, living in sub-Saharan Africa and southern Asia.

Brent Stirton's images tell many stories if you know how to read them -- from the tragedy brought by lack of safe water or too much water, to the joy and life-changing effects that a new water system can offer.

Africa Needs Disease Warning Systems

From Cosmos Magazine:

BARCELONA: Africa needs early warning systems to deal with the increased threat of disease spreading from wild animals to humans caused by climate change, health experts say.

Speaking at the International Union for Conservation of Nature congress in Barcelona, Spain, the scientists said that many wildlife pathogens, such as Ebola, may spread as a result of changing temperatures and precipitation caused by climate change

Monitoring patterns

"Building warning systems and undertaking disease surveillance in places like the Congo Basin would be cheaper than building expensive machines to control an outbreak," said William Karesh, head of the Field Veterinary Program at the Wildlife Conservation Society (WCS).

The early warning systems he suggested include monitoring disease patterns in wild animals, and monitoring environmental changes and how these affect the behaviour of wild animals and pathogens.

According to Karesh, these offer both fertile ground for building early warning systems and areas for future research. "Wild animals are more susceptible to new diseases than domesticated animals, and are good indicators of an impending outbreak," he said.

Volcanoes May Be Original Womb Of Life

From Live Science:

Fifty years ago, a chemist named Stanley Miller conducted a famous experiment to investigate how life could have started on Earth.

Recently, scientists re-analyzed his results using modern technology and found a new implication: The original sparks for life on our planet could have come from volcanic eruptions.

The 1950s experiment was designed to test how the ingredients necessary for life could arise.

Miller and his University of Chicago mentor Harold Urey used a system of closed flasks containing water and a gas of simple molecules thought to be common in Earth's early atmosphere. They zapped the gas with an electric spark (representing lightning on ancient Earth), and found that after a couple of weeks the water turned brown. It turned out that amino acids, the complex molecules that make up proteins, had formed from the simple materials in the flasks.

A New Class of Antibiotics Could Offer Hope Against TB

From Time Magazine:

Eighty years after the discovery of penicillin, researchers say they are on the verge of developing a new class of antibiotics.

Publishing in the Oct. 17 issue of the journal Cell, scientists at Rutgers University describe a group of antibiotic compounds, first isolated decades ago from naturally occurring antibacterial substances in soil. Among them, researchers say, is a compound called myxopyronin that shows great promise. It has been synthesized in the lab and shown to be safe in animal trials, and although the drug hasn't been tested in humans yet, cell-based experiments suggest that it is potent enough to kill a wide range of stubborn bugs, including drug-resistant strains of tuberculosis and the deadly type of staph known as MRSA.

The Rutgers research reflects a much-needed, if slow, renewal of scientific interest in antibiotics development. The last two decades of the 20th century saw nearly zero progress, and in those years several disease-causing bacteria evolved resistance to commonly used drugs. Researchers at the Centers for Disease Control and Prevention found that more than 40% of staph infections in the U.S. in 2006 were MRSA — a bug that now kills more Americans a year than AIDS. Today, the first line of treatment against MRSA is vancomycin, a formidable antibiotic that has been around since the 1950s and is otherwise typically considered a drug of last resort. In the developing world, health workers report a proliferation of XDR (extensively drug-resistant) and MDR (multidrug-resistant) tuberculosis, against which the current first-line antibiotics, rifamycins, developed in the 1960s, have also become useless.

From Yahoo News/AP:

WASHINGTON (AFP) – NASA on Sunday launched a probe into orbit high above earth to study the distant edge of the solar system where hot solar winds crash into the cold outer space.

The Interstellar Boundary Explorer (IBEX) was launched at 1745 GMT, according to images broadcast live by the US space agency.

The small probe was deployed on a Pegasus rocket which dropped from the bay doors of a Lockheed L-1011 jet flying at 12,000 meters (40,000 feet) over the southern Pacific Ocean near the Marshall Islands.

"The count went really smooth... and everything appears to be going well," NASA assistant launch manager Omar Baez said shortly after the launch.

The IBEX is on a two-year mission to take pictures and chart the mysterious confines of the solar system -- including areas billions of kilometers (miles) from earth.

Black And White TV Generation Have Monochrome Dreams

From The Telegraph/Science:

Do you dream in black and white? If so, the chances are you are over 55 and were brought up watching a monochrome television set.

The Passenger Jet That Just Missed Colliding With A UFO 22,000ft Above Kent

From Daily Mail:

As the captain of Flight AZ 284 began his descent into Heathrow, he saw something alarming overhead.

Shaped like a missile, the object suddenly veered across the airliner's path causing the pilot to shout 'Look out!' as he attempted to avert a mid-air collision 22,000ft above the Kent countryside.

Travelling at an estimated 120mph, it passed less than 1,000ft from the passenger jet before disappearing from radar screens, leaving the pilot and accident investigators baffled.

Secret documents released for the first time reveal that Ministry of Defence staff accept that an Unidentified Flying Object zooming above Lydd caused the nearmiss.

The incident took place at 7.58pm on April 21, 1991, and was investigated by the Civil Aviation Authority and military experts.

Having ruled out the possibility of it being a missile, weather balloon or space rocket, the MoD was forced to conclude that it was a genuine UFO and close the inquiry.

The unexplained close encounter is one of many recounted in military UFO documents released today by the National Archives.

The Alitalia aircraft was on a routine flight from Milan to Heathrow with 57 people on board when the ten-foot long object, which had no exhaust flame, was spotted by pilot Achille Zaghetti.

More Problems With Hubble

Hubble Telescope

From Science News:

Hubble’s resurrection is suspended while engineers examine two anomalies
Two anomalies onboard the orbiting Hubble Space Telescope, which stopped transmitting data on September 27, caused engineers to suspend re-activation of Hubble’s science equipment. Engineers encountered problems following an intricate maneuver to circumvent a piece of failed hardware. Hubble is currently orbiting Earth in a dormant “safe mode” while the malfunctions are assessed.

In an October 17 teleconference, NASA scientists said that it is too soon to know the details of the failures. “We are in the early stages of going through a mountain of data that has been downloaded,” said Art Whipple, manager of the Hubble Systems Management Office at NASA’s Goddard Space Flight Center in Greenbelt, Md., at the teleconference. “This is a marathon, not a sprint.”

These latest anomalies came at a critical time, during the team’s attempt on October 16 to wake up all of Hubble’s science equipment and restore the orbiting telescope to full science capabilities.

The late September failure in Hubble’s science data formatting unit halted all science data communications to Earth. Since then, Hubble has been orbiting Earth silently, performing only basic health and safety functions, with almost all of its science observations suspended.

Space Expectations

THE MIND OF WERNHER VON BRAUN: In the October 18, 1952, issue of Collier's, von Braun sketched out the 190-foot- (58-meter-) tall "orbit-to-orbit space ship," which he designed to transport people from a space station to lunar orbit.

From Scientific American:

German rocket physicist and astronautics engineer Wernher von Braun played a crucial role in developing the rocket technology, including the Saturn 5 , that put U.S. astronauts on the surface of the moon in 1969. Just 17 years earlier, when spaceflight was little more than a dream, von Braun worked for the U.S. Army building ballistic missiles. It was during this time that the future and first director of NASA's Marshall Space Flight Center in Huntsville, Ala., would share his vision of manned space exploration. A series of articles published in Collier's magazine in the early 1950s revealed many ideas that later became reality (including space stations, lunar missions and satellites) and some that never got off the ground (a rocket operated by three rhesus monkeys).

Von Braun's sketches for the magazine's illustrations are up for bid by U.K. auctioneers Bonhams Wednesday. The auction house, which expected the lot of 35 drawings and letters to fetch up to $25,000, was pleasantly surprised with the winning bid came in at $132,000.

Their studies show for the first time that the majority of these genes were already in existence at the origin of the first cells.

The search for further genes, particularly those which are involved in diseases caused by several genetic causes, is thus facilitated. Furthermore, the research results confirm that the basic interconnections are to be found in the function of genes - causing the onset of diseases - can also be found in model organisms (Molecular Biology and Evolution).

The Human Genome Project that deciphered the human genetic code, uncovered thousands of genes that, if mutated, are involved in human genetic diseases. The genomes of many other organisms were deciphered in parallel. This now allows the evolution of these disease associated genes to be systematically studied.

Monopoly Brings Out the Worst in People

From Live Science:

Last weekend we had some folks over to play Monopoly. There were four adults and three kids, and we all wanted some family fun.

It's always chancy playing board games with good friends because people with dice in their hands, even very nice, mild mannered people, often turn cutthroat.

With this group, it started as the parents set up the board and the kids ran around.

Half the parents, it seemed, wanted to make sure our fiscally innocent children were protected from unscrupulous players. "Let's let the kids win," said one mother.

But the other parents didn’t give a hoot about the kids. "It's their fault if they don't understand economics. Let's take them for all they've got," said one father.

Men's Reactions Peak At Age 39

From Live Science:

This explains everything.

Scientists asked 72 men, ranging in age from 23 to 80, to tap their index fingers as fast as they could for 10 seconds. The researchers also did brain scans to measure in each subject the amount of myelin — a fatty sheath of insulation that coats nerve axons and allows for signaling bursts in our brains.

Both the tapping speed and the amount of myelin was found to decline "with an accelerating trajectory" after age 39.

Study leader George Bartzokis, professor of psychiatry at UCLA, called the results "pretty striking" and said: "That may well be why, besides achy joints and arthritis, even the fittest athletes retire and all older people move slower than they did when they were younger."

The myelination of brain circuits was known to peak in middle age. Bartzokis and others have long argued that brain aging might be primarily related to the myelin breakdown.

Could Solar Power Satellites Beam Down Gigawatts of Energy?

Image from NASA

From Treehugger:

How pie-in-the-sky is Ben Bova's space satellite scheme? Mr. Bova, the president emeritus of the National Space Society and a prolific science fiction author, penned a column in last Sunday's Washington Post calling on the next president to build an armada of solar power satellites (SPS) -- basically large accumulations of solar cells -- to help meet a substantial chunk of our energy needs. The idea of building orbiting solar systems in space is nothing new (see my posts about Japan's Space Solar Power Systems and India's space plans); the concept, as described by its creator, aerospace engineer Peter Glaser, would be a satellite in high orbit (where sunshine is always present) that would use microwave transmission to beam solar power to receiving stations on Earth.

The obvious benefit: a continuous 24-hour, 365-day supply of solar energy. Powered by solar energy itself, a single SPS could generate up to 10 gigawatts of power continually, according to Bova. If that's even remotely true, just imagine how much continuous power a group of these SPSs could provide.

Protective Shield Of The Sun Is Shrinking


From The Sydney Morning Herald:

LONDON: The protective bubble around the sun that helps to shield the Earth from harmful interstellar radiation is shrinking and getting weaker, NASA scientists have discovered.

New data from the Ulysses deep-space probe show that the heliosphere, the protective shield of energy that surrounds our solar system, has weakened by 25 per cent over the past decade and is now at it lowest level since the space race began 50 years ago.

Scientists, baffled at what could be causing the barrier to shrink in this way, were set to launch a mission overnight to study the heliosphere.

The Interstellar Boundary Explorer, or Ibex, will orbit 240,000 kilometres above the Earth and "listen" for the shock wave that forms as our solar system meets interstellar radiation.

The Final Frontier: An Essay By Stephen Hawkings

From Cosmos Magazine:

In the 1960s the space race created a fascination with science and great technological advances. To find alien life we need to take back up that mantle, says astrophysicist Stephen Hawking, and send people further into space.

Why should we go into space? What is that justification for spending all that effort and money on getting a few lumps of Moon rock? Aren't there better causes here on Earth?

In a way, the situation was like that in Europe before 1492. People might well have argued that it was a waste of money to send Columbus on a wild goose chase over an almost unimaginable distance. Yet, the discovery of the New World made a profound difference to the old one.

Spreading out into space will have an even greater effect; it will completely change the future of the human race and maybe determine whether we have any future at all.

It won't solve many of our immediate problems on Earth, but it will give us a new perspective on them and cause us to look both outwards and inwards. With luck it could unite us to face a common challenge.

Man's Oldest friend: Scientists Discover The Grandad O Modern Dogs... From 31,700 Years Ago

From Daily Mail:

For hundreds of years they've been considered man's best friend, and now it seems dogs have been around longer than thought.

Scientists have discovered the oldest-ever remains of dogs dating back 31,700 years - that's 221,900 in dog years...

The remains push back the date for the earliest dog by 14,000 years, and suggest the forefathers of the modern canine were a lot stronger and a lot hungrier than next-door's Fido.

From studying the fossils, found at Goyet Cave in Belgium, the international team of scientists believe the animals subsisted on a diet of horse, musk ox and reindeer.

Lead author Mietje Germonpré, a paleontologist at the Royal Belgian Institute of Natural Sciences, said: 'In shape, the Paleolithic dogs most resemble the Siberian husky, but in size, however, they were somewhat larger, probably comparable to large shepherd dogs.

'The Paleolithic dogs had wider and shorter snouts and relatively wider brain cases than fossil and recent wolves.'

Colossal Black Holes Common In Early Universe, Spectacular Galactic Collision Suggests

Artist’s conception of the 4C60.07 system of colliding galaxies. The galaxy on the left has turned most of its gas into stars, and the black hole in its center is ejecting charged particles in the two immense jets shown. The galaxy on the right also has a black hole causing the galaxy’s central region to shine, but much of its light is hidden by surrounding gas and dust. Vast numbers of stars are forming out of the gas and dust, and some of the material is being pulled away from the galaxy. (Credit: David A. Hardy/UK ATC)

From Science Daily:

ScienceDaily (Oct. 16, 2008) — Astronomers think that many - perhaps all - galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and galaxies were just beginning to form.

The new conclusion comes from the discovery of two distant galaxies, both with black holes at their heart, which are involved in a spectacular collision.

4C60.07, the first of the galaxies to be discovered, came to astronomers' attention because of its bright radio emission. This radio signal is one telltale sign of a quasar - a rapidly spinning black hole that is feeding on its home galaxy.

When 4C60.07 was first studied, astronomers thought that hydrogen gas surrounding the black hole was undergoing a burst of star formation, forming stars at a remarkable rate - the equivalent of 5,000 suns every year. This vigorous activity was revealed by the infrared glow from smoky debris left over when the largest stars rapidly died.

The Power Of Music


Amazing Power of Music Revealed -- Live Science

More than 7,000 runners who raced earlier this month in a half-marathon in London were under the influence of a scientifically derived and powerful performance-enhancing stimulant — pop music.

The dance-able, upbeat music at London's "Run to the Beat" race was selected on the basis of the research and consultation of sport psychologist Costas Karageorghis of Brunel University in England. He has learned how to devise soundtracks that are just as powerful, if not more so, as some of the not-so-legal substances that athletes commonly take to excel.

"Music is a great way to regulate mood both before and during physical activity. A lot of athletes use music as if it's a legal drug," Karageorghis told LiveScience. "They can use it as a stimulant or as a sedative. Generally speaking, loud upbeat music has a stimulating effect and slow music reduces arousal."

The link between music and athletic performance is just one example of the inroads scientists and doctors are making into understanding the amazing power that music has over our minds and bodies. Science is backing up our intuition and experience, showing that music really does kill pain, reduce stress, better our brains and basically change how we experience life.

Even Moderate Alcohol Seems To Shrink Brain


From Future Pundit:

Using 1,839 subjects in the Framingham Offspring Study examined with functional magnetic resonance imagining (fMRI) researchers find that even lower levels of alcohol drinking are associated with more rapid brain shrinkage with age.

Increasing alcohol intake was associated with loss in total brain volume greater than expected from age alone (P<0.001), reported Carol Ann Paul, of Wellesley College, and colleagues in the October issue of the Archives of Neurology. In the cross-sectional study, women were affected more strongly than men by moderate alcohol intake averaging one to two drinks a day (eight to 14 per week). Do you drink two drinks a day? If so, you are probably getting dumber faster than you need to. The hope was that cardiovascular benefits of moderate alcohol consumption would keep the brain better fed with blood and slow brain aging. But that hope seems unrealistic now. The cardiovascular benefits of low to moderate alcohol intake are thought to result from increasing blood flow rates, which would have been expected to benefit the brain also, Paul said. But rather than preventing normal age-related volume reductions, the effects of moderate drinking were closer to those of heavy drinking, which has been linked to brain atrophy and cognitive decline, the researchers noted.

World's Hottest Ever Planet Is Discovered - At A Sizzling 2250C It's Half As Hot As The Sun!

Hottest ever: The new planet is half the temperature of the Sun (Image from the Daily Mail)

From The Daily Mail:

Scientists have made an amazing discovery in space - the hottest ever planet ever found.

The planet, known as WASP-12b, is believed to be an amazing 2250 Centigrade, about half as hot as the Sun.

The planet, which one and half times the size of Jupiter, orbits at one fortieth the distance between the Earth and the Sun.

Despite the mind-boggling temperature of the new planet, it may not necessarily keep hold of its record for long. Wasp-12b only just edges out the last record-holder HD 149026b, which is a searing 2040 Centigrade.

The discovery was made using two sets of telescopes, one in Spain's Canary Islands and the other in South Africa, to search for signs of 'transiting' planets, which pass in front of and dim their host stars as seen from Earth.

Reading This Will Change Your Brain

From Newsweek:

A leading neuroscientist says processing digital information can rewire your circuits. But is it evolution?

Is technology changing our brains? A new study by UCLA neuroscientist Gary Small adds to a growing body of research that says it is. And according to Small's new book, "iBRAIN: Surviving the Technological Alteration of the Modern Mind," a dramatic shift in how we gather information and communicate with one another has touched off an era of rapid evolution that may ultimately change the human brain as we know it. "Perhaps not since early man first discovered how to use a tool has the human brain been affected so quickly and so dramatically," he writes. "As the brain evolves and shifts its focus towards new technological skills, it drifts away from fundamental social skills."

The impact of technology on our circuitry should not come as a surprise. The brain's plasticity—it's ability to change in response to different stimuli—is well known. Professional musicians have more gray matter in brain regions responsible for planning finger movements. And athletes' brains are bulkier in areas that control hand-eye coordination. That's because the more time you devote to a specific activity, the stronger the neural pathways responsible for executing that activity become. So it makes sense that people who process a constant stream of digital information would have more neurons dedicated to filtering that information. Still, that's not the same thing as evolution.

Mysterious Cyclones Seen At Both of Saturn's Poles


From National Geographic:

Saturn boasts cyclones at each of its poles that dramatically outpower Earth-roving hurricanes, new images reveal.

The Cassini spacecraft—a cooperative project of NASA, the European Space Agency, and the Italian Space Agency—recently peered below what had previously appeared to be isolated cumulus clouds at the planet's south pole.

"What looked like puffy clouds in lower resolution images are turning out to be deep convective structures seen through the atmospheric haze," Cassini imaging team member Tony Del Genio said in a press release.

"One of them has punched through to a higher altitude and created its own little vortex."

"Little" is relative—the eye of the storm is surrounded by an outer ring of clouds that measures 2,500 miles (4,000 kilometers) wide. That's about five times the size of the largest cyclones, or hurricanes, on Earth.

Einstein's Relativity Survives Neutrino Test


From E! Science News:

Physicists working to disprove "Lorentz invariance" -- Einstein's prediction that matter and massless particles will behave the same no matter how they're turned or how fast they go -- won't get that satisfaction from muon neutrinos, at least for the time being, says a consortium of scientists. The test of Lorentz invariance, conducted by MINOS Experiment scientists and reported in the Oct. 10 issue of Physical Review Letters, started with a stream of muon neutrinos produced at Fermilab particle accelerator, near Chicago, and ended with a neutrino detector 750 meters away and 103 meters below ground. As the Earth does its daily rotation, the neutrino beam rotates too.

"If there's a field out there that can cause violations of Lorentz invariance, we should be able to see its effects as the beam rotates in space," said Indiana University Bloomington astrophysicist Stuart Mufson, a project leader. "But we did not. Einsteinian relativity lives to see another day."

Mufson is quick to point out that the Physical Review Letters report does not disprove the existence of a Lorentz-violating field. Despite the sophistication and power of MINOS's detector, "It may be that the field's effects are so exceedingly small that you'd need extraordinary tools to detect it," Mufson said.

Asia Trumping US On Science R&D

(Click To Enlarge)

From Christian Science Monitor:

Federal funding for research has been falling in real terms. Is the nation’s economic edge at stake?

Tallying this year’s Nobel Prizes so far, it’s been a respectable year for US-based scientists. Four shared the prestigious awards – three for chemistry and one as part of an international trio for physics.

As congratulations pour in, however, some science-policy specialists in the United States see troubling signs that federal support for research – measured by checks written rather than checks promised – may be weakening.

To those involved in federally funded research, their work represents a kind of intellectual infrastructure that, if allowed to erode, can begin to undermine the country’s economic competitiveness.

The immediate concern is the continuing resolution the president signed Sept. 30. Congress punted final passage of the federal budget to next March. Except for the Defense Department, other federal agencies responsible for performing or funding research must hold spending at or below fiscal year 2008 levels.

Genetic Reasons For Baldness

Baldness Genes -- Technology Review

Finding the genetic causes could lead to new therapies for baldness.

It may be small comfort to anyone sporting a comb-over, but researchers have found a second genetic risk factor for baldness.

Two groups, working independently, found variants on chromosome 20 that are associated with male pattern baldness--the most common cause of hair loss in men, and the root of a multimillion-dollar industry devoted to protecting, nurturing, and transplanting hair.

A third report identifies a new kind of stem cell in the hair follicles of mice that, when transplanted onto the skin of hairless rodents, causes the animals to sprout tufts of hair.

These latest findings offer greater insight into the genetic underpinnings of male pattern baldness, and into the process that produces a glorious head of hair in the unafflicted. According to a research team led by Tim Spector of King's College London, figuring out the genetic variants linked to the disorder could lead to gene therapies for baldness. The discovery of a risk factor on chromosome 20 may point to "an intriguing new potential target" for gene therapy.

From Science Daily:

ScienceDaily (Oct. 15, 2008) — The discovery of the earliest known cases of human tuberculosis (TB) in bones found submerged off the coast of Israel shows that the disease is 3000 years older than previously thought. Direct examination of this ancient DNA confirms the latest theory that bovine TB evolved later than human TB.

The new research, led by scientists from UCL (University College London) and Tel-Aviv University and published today in PLoS One, sheds light on how the TB bacterium has evolved over the millennia and increases our understanding of how it may change in the future.

The bones, thought to be of a mother and baby, were excavated from Alit-Yam, a 9000 year-old Pre-Pottery Neolithic village, which has been submerged off the coast of Haifa, Israel for thousands of years. Professor Israel Hershkovitz, from Tel-Aviv University's Department of Anatomy, noticed the characteristic bone lesions that are signs of TB in skeletons from the settlement, one of the earliest with evidence of domesticated cattle.

New Evidence Provides An Alternative Route 'Out Of Africa' For Early Humans

From Science Daily:

ScienceDaily (Oct. 15, 2008) — The widely held belief that the Nile valley was the most likely route out of sub-Saharan Africa for early modern humans 120,000 year ago is challenged in a new paper in the Proceedings of the National Academy of Sciences.

A team led by the University of Bristol shows that wetter conditions reached a lot further north than previously thought, providing a wet 'corridor' through Libya for early human migrations. The results also help explain inconsistencies between archaeological finds.

While it is widely accepted that modern humans originated in sub-Saharan Africa 150-200 thousand years ago, their route of dispersal across the hyper-arid Sahara remains controversial. The Sahara covers most of North Africa and to cross it on foot would be a serious undertaking, even today with the most advanced equipment.

Why Women Have Bad Teeth

From Live Science:


Women had poor dental health compared to men back in the hunter-gatherer era, and it got worse as societies turned to farming.

Now an anthropologist is pointing to an overlooked explanation — hormonal and dietary changes related to higher pregnancy rates.

Anthropologists usually argue that women's poor dental health resulted from culture-driven factors, such as cooking duties and the ongoing nibbling that can go along with that. But that narrow focus may overlook biological factors connected to women bearing more and more children in agricultural societies.

Today, men are more likely than women to suffer from gum disease, possibly because men are more likely to ignore dental care, according to Delta Dental. Nonetheless, women do not tend to have better oral health than men, for hormonal reasons, according to the American Academy of Periodontology.
