Mystery Of The Screaming Mummy

Unexpected: Alongside the remains of great Egyptian pharoahs lay the body of a young man, his face locked in an eternal blood-curdling scream, in a plain, undecorated coffin

From the Daily Mail:

It was a blood-curdling discovery. The mummy of a young man with his hands and feed bound, his face contorted in an eternal scream of pain. But who was he and how did he die?

On a scorching hot day at the end of June 1886, Gaston Maspero, head of the Egyptian Antiquities Service, was unwrapping the mummies of the 40 kings and queens found a few years earlier in an astonishing hidden cache near the Valley of the Kings.

The 1881 discovery of the tombs, in the Deir El Bahri valley, 300 miles south of Cairo, had been astonishing and plentiful. Hidden from the world for centuries were some of the great Egyptian pharaohs - Rameses the Great, Seti I and Tuthmosis III. Yet this body, buried alongside them, was different, entombed inside a plain, undecorated coffin that offered no clues to the deceased's identity.

The Great Fear Of The Unknown

Part of the LHC (Large Hadron Collider) is seen in its tunnel at the CERN (European Center for Nuclear Research) near Geneva, Switzerland. By Martial Trezzini, AP

From USA Today:

So much for the end of the world.

Fears that the atom-smashing Large Hadron Collider would create black holes — gravitational sinkholes from which not even light can escape — and end life as we know it have joined UFOs and Bigfoot on the roster of pseudoscientific scares.

Before it was launched on Oct. 10, bloggers, late-night comedians, worried parents around the world and at least two lawsuits greeted the mere start-up of the collider with dismay. But Earth clearly survived the collider's first nine days of operations before a technical glitch shut it down.

Experts at the European Organization for Nuclear Research (CERN — an acronym kept from an earlier name), which created the $6 billion grand experiment in particle physics, are resigned to the scares kicking up again when the collider starts back up next year and begins smashing protons.

"It's only natural. We are curious about the unknown, and that's why we explore mysteries like the conditions of the early universe," says CERN spokesman James Gillies. "At the same time, we fear the unknown, and particle physics can be one of those things that is hard for people to understand."

From Yahoo News/AP:

CAPE CANAVERAL, Fla. – The international space station is about to get all the comforts of a modern, high-end, "green" home: a fancy recycling water filter, a new fridge, extra bedrooms, workout equipment and the essential half-bath.

Later this week, space shuttle Endeavour's seven astronauts will carry up all the frills for more luxurious space station living — and a larger household. Liftoff is set for Friday night.

It will be a home makeover in the extreme. The space station will go from a three-bedroom, one-bath house with kitchenette to a five-bedroom, two-bath house with two kitchenettes and the latest gizmos NASA has to offer.

Are Alternative Fuels Reliving The 1980s?

Workers install solar panels on the roof of an Austin, Texas, home.
(Ann Hermes/CSM/File)

From Christian Science Monitor:

Today’s slumping oil prices may undermine viability of alt-fuel programs – again.

Tumbling gas-pump prices make motorists smile, but not Peter Vanderzee. They remind him how falling oil costs sank his effort to unshackle the United States from Middle East oil two decades ago.

As project manager for two large alternative-energy projects under President Carter’s US Synthetic Fuels program launched in 1980, Mr. Vanderzee was pushing his team to make methanol from coal for auto fuel.

But in 1985, just as his technology was starting to produce results, oil plummeted. In today’s inflation-adjusted dollars, oil went from $53 a barrel to $28, with pump prices falling from $2.20 a gallon to $1.60. The next year, President Reagan pulled the plug on the US Synfuels program.

'Anti-Aging' Pill Makes Mice Mighty

Mighty and Mini
After 15 weeks a high-calorie diet, mice taking at least 500 mg of a new drug gained no weight. Meanwhile, their cholesterol levels improved and their running ability got a measurable boost. But don't run to the pharmacy: for now, this prescription is for rodents only.

From Discovery:

Nov. 7, 2008 -- Eat more than you should. Stay skinny. Run twice as far. Those are the big claims coming from a new drug study from Sirtris Pharmaceuticals, Inc., based in Cambridge, Mass. This latest study clears the way for human clinical trials of SRT1720, often touted as an "anti-aging pill."

SRT1720 activates the same receptor as the much-discussed resveratrol, the chemical in red wine that may slow some effects of aging. Both resveratrol and SRT1720 are being tested as a way to treat type-two diabetes first, and possibly other age-related diseases, later.

"We are very excited by these results," said Michelle Dipp of Sirtris. "These compounds are mimicking calorie restriction and exercise while lowering levels of glucose and insulin in mice. It's a game changer."

(Image: NASA/JPL-Caltech)

New Scientist Space:

The arrival of spring in southern Mars is reviving NASA's two venerable Mars rovers as deepening autumn in the arctic north slowly freezes the Phoenix lander.

After hibernating for the winter on the northern edge of a plateau called Home Plate, the Spirit rover moved uphill in October to collect more sunlight.

On the other side of the planet, the Opportunity rover, which climbed out of a large crater called Victoria at the end of August, has completed the first month of a 12-kilometre trek towards an even bigger crater called Endeavour. That journey is expected to take more than two years.

Designed to last only 90 days, the two rovers have survived for nearly five years on the Red Planet. Both are showing their age, but Jake Matijevic, chief of rover engineering at NASA's Jet Propulsion Laboratory in Pasadena, California, says they still are doing fine.

Prefabulous: 9 Amazingly Modern Factory Built Homes

From Style Crave:

Factory-built homes have a “trailer park” stigma no more. These amazing modern homes are built in a factory then shipped to site. Not only is the process more efficient and less expensive, it is the green way to build a quality, sustainable home. Process aside, these homes are beautiful, and much cheaper than any comparable site-built home on the market. Here are 9 of the USA’s greatest modern prefab homes…

For those who are new to the world of prefab architecture, the process is basic. An architect develops a plan for a home, but instead of contracting the development to a builder, they build the home in sections in a climate-controlled warehouse. These sections are then shipped to the final worksite where they are joined and finalized into a finished home. This process is more cost-effective as it takes advantage of bulk material purchasing and construction, it avoids weather-induced delays, it maintains a regular staff familiar to the blueprints and allows for a greater level of control over quality. Now that you’re up to speed, here are 9 reasons why your next home might just be a prefab.

(Credit: Hansen, et al/Open Atmospheric Science Journal)

From Science Daily:

ScienceDaily (Nov. 9, 2008) — If climate disasters are to be averted, atmospheric carbon dioxide (CO2) must be reduced below the levels that already exist today, according to a study published in Open Atmospheric Science Journal by a group of 10 scientists from the United States, the United Kingdom and France.

The authors, who include two Yale scientists, assert that to maintain a planet similar to that on which civilization developed, an optimum CO2 level would be less than 350 ppm — a dramatic change from most previous studies, which suggested a danger level for CO2 is likely to be 450 ppm or higher. Atmospheric CO2 is currently 385 parts per million (ppm) and is increasing by about 2 ppm each year from the burning of fossil fuels (coal, oil, and gas) and from the burning of forests.

Earth Can't Cope, New Planets Needed

From Live Science:

In their recent Living Planet Report for this year, the World Wildlife Federation is suggesting that this planet's resources won't be enough for us.

"The Earth’s biocapacity is the amount of biologically productive area – cropland, pasture, forest, and fisheries – that is available to meet humanity’s needs.

"Since the late 1980s, we have been in overshoot - the Ecological Footprint has exceeded the Earth’s biocapacity - by about 25%.

"Effectively, the Earth’s regenerative capacity can no longer keep up with demand – people are turning resources into waste faster than nature can turn waste back into resources.

"A moderate business-as-usual scenario, based on United Nations projections of slow, steady growth of economies and populations, suggests that by 2050, humanity’s demand on nature will be twice the biosphere’s productive capacity [graph]."

Unknown "Structures" Tugging At Universe, Study Says

The so-called Bullet Cluster of galaxies lies 3.8 billion light-years away. It's one of hundreds that have been found to be carried along by a mysterious "dark flow," an October 2008 study says. The dark flow is caused by unknown clumps of matter outside the known universe, which are pulling our entire universe toward them, the study suggests. The report hints that, whatever may be beyond the known universe, it's like nothing we know. Image courtesy NASA/STScI/Magellan/U. Arizona/D. Clowe, et al

From The National Geographic:

Something may be out there. Way out there.

On the outskirts of creation, unknown, unseen "structures" are tugging on our universe like cosmic magnets, a controversial new study says.

Everything in the known universe is said to be racing toward the massive clumps of matter at more than 2 million miles (3.2 million kilometers) an hour—a movement the researchers have dubbed dark flow.

The presence of the extra-universal matter suggests that our universe is part of something bigger—a multiverse—and that whatever is out there is very different from the universe we know, according to study leader Alexander Kashlinsky, an astrophysicist at NASA's Goddard Space Flight Center in Maryland.

Mini Nuclear Plants To Power 20,000 Homes

From The Guardian:

£13m shed-size reactors will be delivered by lorry

Nuclear power plants smaller than a garden shed and able to power 20,000 homes will be on sale within five years, say scientists at Los Alamos, the US government laboratory which developed the first atomic bomb.

The miniature reactors will be factory-sealed, contain no weapons-grade material, have no moving parts and will be nearly impossible to steal because they will be encased in concrete and buried underground.

The US government has licensed the technology to Hyperion, a New Mexico-based company which said last week that it has taken its first firm orders and plans to start mass production within five years. 'Our goal is to generate electricity for 10 cents a watt anywhere in the world,' said John Deal, chief executive of Hyperion. 'They will cost approximately $25m [£13m] each. For a community with 10,000 households, that is a very affordable $250 per home.'

First Complete Cancer Genome Sequenced

These acute myeloid leukemia cells are from the bone marrow of the female patient whose complete genome was sequenced in the first decoding of a complete cancer genome. The genetic study implicated eight genes not previously associated with this form of cancer. Timothy Ley

From Science News:

Scientists decipher each of the 3 billion DNA bases from the genome of an acute myeloid leukemia tumor

For the first time, a complete cancer genome, and incidentally a complete female genome, has been decoded, scientists report online Nov. 5 in Nature. In a study made possible by faster, cheaper and more sensitive methods for sequencing DNA, the researchers pinpoint eight new genes that may cause a cell to turn cancerous.

“Since cancer is a disease of the genome, this newfound ability to determine the complete DNA sequence of a cancer cell is enormously powerful,” comments Francis Collins, a geneticist and former director of the National Human Genome Research Institute in Bethesda, Md., a group that raced to sequence the first entire human genome.

Has Biodefense Spending Made Us Safer

Postal Anthrax Aftermath: Has Biodefense Spending Made Us Safer? -- Scientific American

The Anthrax attacks in 2001 led to a massive increase in biodefense funding, which critics claim has done more harm than good.

As the Federal Bureau of Investigation was about to move in, U.S. Army biodefense scientist Bruce Ivins committed suicide, thus possibly closing the chapter on the first—and so far only—fatal bioattack in U.S. history. The FBI alleges that Ivins, who worked at the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) in Fort Detrick, Md., mailed anthrax-laden letters in September and October 2001 that killed five people. The incidents sparked a massive infusion of research funds to counter civilian bioterrorism, $41 billion spread over seven federal departments and agencies. Yet some observers argue that those funds have done little to guard against another bioterror incident, especially if the FBI is right about Ivins.

The Historic Beginnings Of The Space Arms Race Part Two

From Space War:

he Soviet government was set to adopt the Polyot-Kosmos anti-satellite -- ASAT -- weapons system after Kosmos-252 successfully destroyed the first spacecraft in orbit on Nov. 1, 1968, and after successful subsequent launches.

However, in 1972 the Soviet Union and the United States signed the Strategic Arms Limitation Treaty -- SALT-I -- and the Anti-Ballistic Missile -- ABM -- Treaty, which also covered ASAT systems.

Depending on the pace of bilateral talks, the ASAT test program was either mothballed or resumed. The ASAT system was eventually adopted and subsequently upgraded.

In 1976 the Soviet Union began to launch second-generation satellite interceptors, featuring new target-acquisition and homing systems, first installed aboard Kosmos-814. Flying along a lower orbit, the latter quickly overtook the target satellite, accelerated and found itself less than 1,000 meters from the "victim."

Physics The Next President Needs To Know

From Wired:

Physics may be the furthest thing from the minds of the presidential candidates right now, but a solid grasp of the science behind some of the latest headlines will be critical for the winner.

Physics has a history of intersecting with politics in ways both large and small, from the creation of the atomic bomb to nuclear meltdowns to terrorist methods. And now, with more specialized, high-tech issues to tackle than ever before, it is increasingly important that world leaders have an understanding of the underlying scientific concepts.

But that’s not necessarily the case, says UC Berkeley physicist Richard Muller, author of the book Physics for Future Presidents. For example, he argues that some terrorist threats, like dirty bombs, are overrated, while others, the low-tech stuff like natural gas bombs, receive little attention.

Ancient Cave Yields Clues to Chinese History

From Live Science:

WASHINGTON (AP) — A stalagmite rising from the floor of a cave in China is providing clues to the end of several dynasties in Chinese history.

Slowly built from the minerals in dripping water over 1,810 years, chemicals in the stone tell a tale of strong and weak cycles of the monsoon, the life-giving rains that water crops to feed millions of people.

Dry periods coincided with the demise of the Tang, Yuan and Ming dynasties, researchers report in Friday's edition of the journal Science.

In addition, the team led by Pingzhong Zhang of Lanzhou University in China noted a change in the cycles around 1960 which they said may indicate that greenhouse gases released by human activities have become the dominant influence on the monsoon.

The Wanxiang Cave is in Gansu Province, a region where 80 percent of the rainfall occurs between May and September.

How Anesthesia Knocks You Out

From Live Science:

During surgery, anesthesia immobilizes a person while putting them in a sleep-like state where there is no awareness and no pain.

But after more than a century of "going under," we still do not fully understand how anesthesia works, said Anthony Hudetz in the Department of Anesthesiology at the Medical College of Wisconsin, Milwaukee.

New research by Hudetz and his colleagues now suggests that anesthesia somehow disrupts information connections in the mind and perhaps inactivates two regions at the back of the brain.

Here's how it works: Think of each bit of information coming into the brain as the side of a die. Then, the first step in consciousness would be to identify which number or state turns up once you throw the die. But you can't identify that number without access to the other faces of the die. That's because every experience, every perception (or number in this example) is connected to all the others. When the faces of the die somehow become disconnected, a person would fall unconscious.

From Science Daily:

ScienceDaily (Nov. 6, 2008) — The search for a mysterious substance which makes up most of the Universe could soon be at an end, according to new research.

Dark matter is believed to account for 85 per cent of the Universe's mass but has remained invisible to telescopes since scientists inferred its existence from its gravitational effects more than 75 years ago.

Now the international Virgo Consortium, a team of scientists including cosmologists at Durham University, has used a massive computer simulation showing the evolution of a galaxy like the Milky Way to "see" gamma-rays given off by dark matter.

They say their findings, published in the prestigious scientific journal Nature (Thursday, November 6), could help NASA's Fermi Telescope in its search for the dark matter and open a new chapter in our understanding of the Universe.

Energy Agency Warns Of 6°C Rise In Temperatures

From New Scientist Environment:

Our voracious appetite for energy is potentially putting the planet on the path for a 6°C rise in temperatures – which is far more than what climate specialists say the environment can cope with.

In its 2008 World Energy Outlook, the International Energy Agency says the 2009 Copenhagen climate summit will have to set ambitious carbon-limiting caps and that the energy sector must play a key role in making this possible.

European policy-makers have set themselves the goal of keeping temperature rises below 2°C relative to what they were before the industrial revolution. Last year, the Intergovernmental Panel on Climate Change issued its forecasts of how rises between 1°C and 5°C would change the environment (see table in Climate hange is here now, says major report). A rise of 6°C was off the charts.

How Disease Can Wipe Out An Entire Species

Photo by Patricia Wynne
This illustration shows the rat species Rattus nativitatis, which went extinct on Australia's Christmas Island by 1908. In a new study of museum DNA samples, researchers report that the likely cause of the animals' extinction was an introduced disease.

From The MSNBC:

Rat study presents first evidence for extinction due to ‘hyperdisease’.

Disease can wipe out an entire species, reveals a new study on rats native to Australia's Christmas Island that fell prey to "hyperdisease conditions" caused by a pathogen that led to the rodents' extinction.

The study, published in the latest issue of the journal PLoS One, presents the first evidence for extinction of an animal entirely because of disease.

The researchers say it's possible for any animal species, including humans, to die out in a similar fashion, although a complete eradication of Homo sapiens would be unlikely.

"I can certainly imagine local population or even citywide 'extinction,' or population crashes due to introduced pathogens under a condition where you have a pathogen that can spread like the flu and has the pathogenicity of the 1918 flu or Ebola viruses," co-author Alex Greenwood, assistant professor of biological sciences at Old Dominion University in Norfolk, Va., told Discovery News.

A daily dose of an investigational medication has been found to restore muscle mass in the arms and legs of older adults and improve some of their biochemistry to levels found in healthy young adults, suggesting an anti-frailty drug has been found.

The drug, called MK-677, was evaluated for its safety and effectiveness in a study that showed the drug restored 20 percent of muscle mass loss associated with normal aging. In fact, levels of growth hormone (GH) and of insulin-like growth factor I (IGF- I) in healthy seniors who took the drug increased to the levels found in healthy young adults, said Michael O. Thorner, a professor of internal medicine and neurosurgery at the University of Virginia Health System.

Gobekli Tepe: The World’s First Temple?

From The Smithsonian:

Predating Stonehenge by 6,000 years, Turkey's stunning Gobekli Tepe upends the conventional view of the rise of civilization.

Six miles from Urfa, an ancient city in southeastern Turkey, Klaus Schmidt has made one of the most startling archaeological discoveries of our time: massive carved stones about 11,000 years old, crafted and arranged by prehistoric people who had not yet developed metal tools or even pottery. The megaliths predate Stonehenge by some 6,000 years. The place is called Gobekli Tepe, and Schmidt, a German archaeologist who has been working here more than a decade, is convinced it's the site of the world's oldest temple.

"Guten Morgen," he says at 5:20 a.m. when his van picks me up at my hotel in Urfa. Thirty minutes later, the van reaches the foot of a grassy hill and parks next to strands of barbed wire. We follow a knot of workmen up the hill to rectangular pits shaded by a corrugated steel roof—the main excavation site. In the pits, standing stones, or pillars, are arranged in circles. Beyond, on the hillside, are four other rings of partially excavated pillars. Each ring has a roughly similar layout: in the center are two large stone T-shaped pillars encircled by slightly smaller stones facing inward. The tallest pillars tower 16 feet and, Schmidt says, weigh between seven and ten tons. As we walk among them, I see that some are blank, while others are elaborately carved: foxes, lions, scorpions and vultures abound, twisting and crawling on the pillars' broad sides.

(Image: Fermilab)

From The New Scientist Space:

While engineers at the Large Hadron Collider (LHC) race to fix its teething problems and start looking for new particles, its ageing predecessor is refusing go silently into the night.

Last week, physicists announced that the Tevatron particle accelerator at Fermilab in Batavia, Illinois, has produced particles that they are unable to explain. Could it be a sign of new physics?

The Collider Detector at Fermilab (CDF) monitors the particles that spew from collisions between protons and anti-protons, which are accelerated and smashed head-on by the Tevatron. The collision occurs inside the 1.5-centimetre-wide "beam pipe" that confines the protons and anti-protons, and the particles created are tracked by surrounding layers of electronics.

From Breitbart/AFP:

Japanese scientists said Tuesday they had created a mouse from a dead cell frozen for 16 years, taking a step in the long impossible dream of bringing back extinct animals such as mammoths.

Scientists at the government-backed research institute Riken used the dead cell of a mouse that had been preserved at minus 20 degrees Celsius (minus 4 degrees Fahrenheit) -- a temperature similar to frozen ground.

The scientists hope that the first-of-a-kind research will pave the way to restore extinct animals such as the mammoth.

The findings were published in the Proceedings of the National Academy of Sciences in the United States.

The scientists extracted a cell nucleus from an organ of the dead mouse and planted it into an egg of another mouse which was alive, leading to the birth of the cloned mouse, the researchers said.

From Boston.com:

Dockworker Marcy Ingall saw a giant wave in the distance last Tuesday afternoon and stopped in her tracks. It was an hour before low tide in Maine's Boothbay Harbor, yet without warning, the muddy harbor floor suddenly filled with rushing, swirling water.

In 15 minutes, the water rose 12 feet, then receded. And then it happened again. It occurred three times, she said, each time ripping apart docks and splitting wooden pilings.

"It was bizarre," said Ingall, a lifelong resident of the area. "Everybody was like, 'Oh my God, is this the end?' " It was not the apocalypse, but it was a rare phenomenon, one that has baffled researchers. The National Weather Service said ocean levels rapidly rose in Boothbay, Southport, and Bristol in a matter of minutes around 3 p.m. on Oct. 28 to the surprise of ocean watchers. Exactly what caused the rogue waves remains unknown.

Grapes Slow Development Of High Blood Pressure In Rats

From Future Pundit:

The researchers studied the effect of regular table grapes (a blend of green, red, and black grapes) that were mixed into the rat diet in a powdered form, as part of either a high- or low-salt diet. They performed many comparisons between the rats consuming the test diet and the control rats receiving no grape powder — including some that received a mild dose of a common blood-pressure drug. All the rats were from a research breed that develops high blood pressure when fed a salty diet.

In all, after 18 weeks, the rats that received the grape-enriched diet powder had lower blood pressure, better heart function, reduced inflammation throughout their bodies, and fewer signs of heart muscle damage than the rats that ate the same salty diet but didn't receive grapes. The rats that received the blood-pressure medicine, hydrazine, along with a salty diet also had lower blood pressure, but their hearts were not protected from damage as they were in the grape-fed group.

Bacteria On The Move, Eating Their Fill

The rippling pattern of a swarm of M. xanthus moving over their prey. John R. Kirby/University of Iowa Carver College of Medicine

From The New York Times:

Bacteria move in mysterious ways. Myxococcus xanthus, for example, a harmless soil microbe, forms rippling swarms by the millions as it devours other microbes as prey.

This organized back-and-forth behavior “was thought to occur particularly in response to starvation,” said John R. Kirby, a microbiologist at the University of Iowa. But Dr. Kirby, James E. Berleman and others at Iowa report in The Proceedings of the National Academy of Sciences that M. xanthus acts this way in response to food, and uses chemical sensing and signaling pathways to do so.

Directed bacterial movement that is controlled in this way is known as chemotaxis, and has been observed in individual microbes as well as in colonies that organize into biofilms or other structures. Because M. xanthus uses chemotaxis-like pathways to move over its prey, the researchers call this behavior predataxis. (A video is at nytimes.com/science.)

DARPA Developing A Device That Stops Internal Bleeding Using Ultrasounds

(Image from Device Daily)

From Device Daily:

When I hear about an interesting technology project, I’m always thinking that DARPA is involved as there guys always come up with the best of things which is absolutely normal due to the enormous funding coming from tax payers. DARPA’s latest project is called DBAC, or Deep Bleeder Acoustic Coagulation, and it consists of a device which stops internal bleeding almost instantaneously.

Internal bleeding is very dangerous and it’s very important to cure soldiers wounded in battle, but also for people who suffer car or other accidents. Irreversible hemorrhagic shock can be caused by internal bleeding which can kill soldiers, and now DARPA is trying to develop a portable device that will detect and stop the bleeding using ultrasounds.

DARPA has contracted the University of Washington’s Centre for Industrial and Medical Ultrasound and Texas A&M to develop the DBAC cuff which should be semi-automatic and any soldier with minimal training will be able to operate it.

My Comment: This is going to save a lot of lives. The focus of this tech is on soldiers, but its applications can be used everywhere.

Commercial Production of Chickens Takes Toll on Genetic Diversity

From New York Times:

To the connoisseur of fine food, chicken may seem depressingly monotonous no matter how it’s prepared. But scientists worry about a more basic degree of sameness — a lack of genetic diversity in the birds that are raised for meat and eggs.

An analysis of commercial chicken populations around the world by William M. Muir of Purdue University and colleagues has revealed the extent of the problem. Fifty percent or more of the diversity of ancestral breeds has been lost, they report in The Proceedings of the National Academy of Sciences. That could make chicken production more susceptible to disease outbreaks for which resistant genes have disappeared.

Sampling about 2,500 birds, the researchers looked at several thousand instances of genetic variation and used that to estimate what a hypothetical ancestral population looked like genetically. “Then we were able to say what is missing” in commercial birds, Dr. Muir said.

15 New Technologies That Will Change Everything

From MSNBC:

The Next Big Thing? The memristor, a microscopic component that can "remember" electrical states even when turned off. It's expected to be far cheaper and faster than flash storage. A theoretical concept since 1971, it has now been built in labs and is already starting to revolutionize everything we know about computing, possibly making flash memory, RAM, and even hard drives obsolete within a decade.

The memristor is just one of the incredible technological advances sending shock waves through the world of computing. Other innovations in the works are more down-to-earth, but they also carry watershed significance. From the technologies that finally make paperless offices a reality to those that deliver wireless power, these advances should make your humble PC a far different beast come the turn of the decade.

In the following sections, we outline the basics of 15 upcoming technologies, with predictions on what may come of them. Some are breathing down our necks; some advances are still just out of reach. And all have to be reckoned with.

Mexico City's 'Water Monster' Nears Extinction

Sep. 27: An Axolotl salamander, or Ambystoma mexicanum, swims in a tank
at the Chapultepec Zoo in Mexico City.

From FOX News:

MEXICO CITY — Beneath the tourist gondolas in the remains of a great Aztec lake lives a creature that resembles a monster — and a Muppet — with its slimy tail, plumage-like gills and mouth that curls into an odd smile.

The axolotl, also known as the "water monster" and the "Mexican walking fish," was a key part of Aztec legend and diet. Against all odds, it survived until now amid Mexico City's urban sprawl in the polluted canals of Lake Xochimilco, now a Venice-style destination for revelers poled along by Mexican gondoliers, or trajineros, in brightly painted party boats.

But scientists are racing to save the foot-long salamander from extinction, a victim of the draining of its lake habitat and deteriorating water quality. In what may be the final blow, nonnative fish introduced into the canals are eating its lunch — and its babies.

Consuming Small Amounts Of Caffeine When Pregnant May Affect The Growth Of An Unborn Child

From E! Science News:

Consuming caffeine at any time during pregnancy is associated with an increased risk of fetal growth restriction (low birth weight), according to research published on bmj.com today. Although some previous studies have also shown this, this BMJ study additionally shows that any amount and type of caffeine intake—from tea, cola, chocolate, cocoa, and some prescription drugs, as well as coffee—is linked with relatively slower fetal growth.

Dr Justin Konje and colleagues from the University of Leicester as well as collaborators from the University of Leeds, examined the association of maternal caffeine intake and individual caffeine metabolism on birth weight.

From two large teaching hospitals in the UK between September 2003 and June 2006 the authors recruited 2645 low risk pregnant women of average age 30, who were between 8-12 weeks pregnant. They used a caffeine assessment tool (CAT) to record caffeine intake from all possible dietary sources in the four weeks before and throughout pregnancy, and also used a saliva sample test to calculate individual caffeine metabolism

From Live Science:

Editor's Note: Each Wednesday LiveScience examines the viability of emerging energy technologies — the power of the future.

As the U.S. election season draws to a close, one of the biggest environmental issues has been "clean coal." Both candidates for president have come out in support of it.

Some environmentalists say it is an oxymoron, while others feel it is a viable option for using abundant coal reserves wisely. The debate is complicated by the fact that clean coal is not well-defined.

"It's an abused term that people use to justify whatever they are doing," said John Thompson, director of the Clean Air Task Force's Coal Transition Project.

For some, clean coal means reducing the pollutants that cause smog and acid rain, but for others this is not enough: They say coal remains dirty as long as it continues to release the greenhouse gas carbon dioxide into the atmosphere.

"I am an environmentalist, and the reality is that coal is killing the planet as we are using it," Thompson told LiveScience.

From Live Science:

An Australian zoologist is leading a national project to help save the endangered Tasmanian devil from extinction, a situation that could arise within the next 20 years, experts predict.

Jeremy Austin will lead the project, which has received $168,000 Australian (Australian dollars currently are about two-thirds the value of U.S. dollars) from that nation's government. The research will rely on genetic procedures to examine the impact of an infectious cancer, devil facial tumor disease, on Tasmanian devils.

Tasmanian devils became extinct on the Australian mainland about 400 years ago and are now found only on the Australian island state of Tasmania. Unlike Tasmanian tigers, devils survived initial human impacts following European colonization but in the past decade their numbers have fallen drastically.

"We have lost over half our devils in the past 10 years, with an estimated population of 20,000 to 50,000 mature devils left. Extinction within the next 20 years is a real possibility unless we find a vaccine, eradicate the disease and establish captive colonies," Austin said.

Earth Getting 'Overcrowded'

From IOL:

Humankind will need two planets by 2030 to keep up with its demands for goods and to make space for surging populations.

This is according to the influential WWF Living Planet Report 2008, which warns that humanity is consuming the resources provided by Earth's natural systems much too fast.

Earth, it declares, is facing a looming ecological credit crunch and the current financial recession pales in comparison.

"Reckless consumption is endangering our future prosperity," writes James Leape, the director general of WWF International, in the report.

"Yet our demands continue to escalate, driven by the relentless growth in human population and individual consumption. Our global footprint now exceeds the world's capacity to regenerate by 30 percent. If our demands on the planet continue at the same rate, by the mid-2030s, we'll need the equivalent of two planets to maintain our lifestyles."

Even A Little Caffeine May Harm Fetus, Study Finds

From Yahoo/Reuters:

LONDON (Reuters) – Pregnant women who consume caffeine -- even about a cup of coffee daily -- are at higher risk of giving birth to an underweight baby, researchers said on Monday.

The new findings published in the British Medical Journal (BMJ) also linked any source of caffeine, including that from tea, cola, chocolate and some prescription drugs, to relatively slower fetal growth.

The findings are the latest in mounting evidence indicating the amount of caffeine a person consumes may directly impact one's health, especially when pregnant.

In January, U.S. researchers found that pregnant women who drink two or more cups of coffee a day are at twice the risk of having a miscarriage as those women who avoid caffeine.

Babies born underweight are more likely to develop a range of health conditions when they grow older, including high blood pressure, diabetes and heart problems.

Women who drank one to two cups of coffee daily, or between 100-199 milligrams, had a 20 percent increased risk of having a baby of low birth weight, the study found. This was compared to women who consumed less than 100 milligrams daily.

What Fills The Space Left In Wells When Oil Is Extracted From The Ground?

Fire Down Below: Oil wells dip 30,000 feet below ground -- still too shallow to hit magma:

From Popsci:

You might guess that magma or tumbling rocks fill the void, but the truth is much more prosaic: water. Petroleum deposits, which are naturally mixed with water and gas, lie thousands of feet below the earth’s surface in layers of porous rock, typically sandstone or limestone. (Contrary to what you might imagine, drilling for oil is more like sucking oil from a sponge with a straw than from a giant pool of liquid.) At such depths, these liquids are under very high pressure. Pump petroleum out, and the pressure in the well drops. Water in the surrounding rock, which is also packed under high pressure, then pushes its way into this low-pressure pocket until the pressure reaches equilibrium. “It’s just like digging a hole at the beach, where water in the sand around it flows into the lower pressure zone of the hole,” explains Chris Liner, a professor of petroleum seismology at the University of Houston.

China Carbon Emissions Might Double By 2030

From Future Pundit:

China's increase in carbon dioxide emissions over the next 20 years will exceed current US emissions.

By 2020, China's burning of fossil fuels could annually emit carbon dioxide equal in mass to 2.5 billion metric tonnes of pure carbon and up to 2.9 billion tonnes, depending on varying scenarios for development and technology, the new report states. By 2030, those annual emissions may reach 3.1 billion tonnes a year and up to 4.0 billion tonnes.

That compares with global carbon emissions of about 8.5 billion tonnes in 2007.

...The U.S. Oak Ridge National Laboratory estimated that the United States emitted about 1.6 billion tonnes of carbon in 2007, compared to China's 1.8 billion tonnes.

Could A Hyperactive Hamster Power Your House? All The Answers To The World's Most Pointless Questions

From Daily Mail:

They're those baffling questions that pop into the brain when you've nothing better to think about, and only the appliance of a large helping of science can answer. Now a new book by the experts at New Scientist magazine solves some of the most intriguing queries sent in by readers...

Why does bottled water from a 3,000-year-old source - such as a spring, mountain or glacier - carry a 'best before' date only two years in the future?

The water has passed through layers of rock that have different effects on it. Some minerals dissolve in the water, supposedly improving both its taste and health-giving properties.

The minute pores in the rocks that the water passes through also act as a filtration system, improving purity by removing larger molecules such as biological contaminants. As soon as the pure water emerges from the aquifer it has filtered through, however, it is vulnerable to contamination again.

The 'best before' dates on bottles are based on the amount of time the manufacturer believes the water will remain without measurable levels of contamination due to the lack of completely sterile conditions in their bottling plants.

If the water is stored in a plastic bottle, the date will also relate to contamination from the constituents of the plastic, which may change the taste of the water.

Flying On A Wing And ... Paper

From Scientific American:

Paper airplane contest awards the flimsy fliers that are a cut above the rest

The centerpiece of classroom mischief will come into its own this weekend when amateur aviation engineers test the mettle of their paper planes at the non-for-profit Public Art Fund's New Millennium Paper Airplane Contest in New York City.

As many as 200 participants are expected to battle it out for such titles as the paper creation that flies the farthest, is the most beautiful—and even the one that puts in a performance deemed the most "spectacular failure." The rules are simple: paper must be 8.5 by 11 inches (21.6 by 28 centimeters) or smaller; cutting and gluing is okay, but stapling is not. Tiny planes folded from gum wrappers make the cut, as do graceful bird-inspired crafts, angular jets, and tiny mothlike fliers.

Competitors will be arranged in heats at the event, which is being held Saturday from 1 P.M. to 5 P.M. in the New York Hall of Science in Queens. Wannabe contenders who can't make it to NYC are invited to send their paper planes for designated proxies to fly. And, yes, the winners will get trophies.

More Methane A Mystery

Methane Molecule (Image from Wikimedia)

From News 24:

Washington - Levels of climate-warming methane - a greenhouse gas 25 times as potent as carbon dioxide - rose abruptly in the earth's atmosphere last year, and scientists who reported the change don't know why it occurred.

Methane, the primary component of natural gas, has more than doubled in the atmosphere since pre-industrial times, but stayed largely stable over the last decade or so before rising in 2007, researchers said on Wednesday.

This stability led scientists to believe that the emissions of methane, from natural sources like cows, sheep and wetlands, as well as from human activities like coal and gas production, were balanced by the destruction of methane in the atmosphere.

But that balance was upset starting early last year, releasing millions of metric tonnes more methane into the air, the scientists wrote in the Geophysical Research Letters.

"The thing that's really surprising is that it's coming after this period of very level emissions," said Matthew Rigby of the Massachusetts Institute of Technology (MIT).

"The worry is that we just don't understand the methane cycle very well."
