Nuclear Fusion Fission Hybrid Reactor To Destroy Waste

Photo from ABC News (Australia)

From Future Pundit:

The idea behind long term (tens or hundreds of thousands of years) nuclear waste storage facilities is that we can't solve the nuclear waste disposal problem quickly. But matter is so manipulable in the hands of sufficiently smart scientists and technologists that sometimes supposedly insolvable problems become solvable. UT Austin researchers think they know how to convert nuclear power plant waste into far safer elements with a hybrid reactor.

AUSTIN, Texas--Physicists at The University of Texas at Austin have designed a new system that, when fully developed, would use fusion to eliminate most of the transuranic waste produced by nuclear power plants.

From Science Daily:

ScienceDaily (Feb. 2, 2009) — Over 14,000 years ago during the last Pleistocene Ice Age, when a large part of the European continent was covered in ice and snow, Neanderthals in the region of Gibraltar in the south of the Iberian peninsula were able to survive because of the refugium of plant and animal biodiversity. Today, plant fossil remains discovered in Gorham's Cave confirm this unique diversity and wealth of resources available in this area of the planet.

The international team jointly led by Spanish researchers has reconstructed the landscape near Gorham's Cave in Gibraltar, by means of paleobotanical data (plant fossil records) located in the geological deposits investigated between 1997 and 2004. The study, which is published in the Quaternary Science Reviews, also re-examines previous findings relating to the glacial refugia for trees during the ice age in the Iberian Peninsula.

From Live Science:

The federal government has approved the first study by a company that will use human embryonic stem cells injected into a human.

The Geron corporation announce the approval today. The therapy used in the study is designed to treat spinal cord injuries by injecting stem cells — which are able to transform into the many different types of cells we need in our bodies — directly into the patients' spinal cords.

The U.S. Food and Drug Administration (FDA) granted clearance of the company's application for the clinical trial of GRNOPC1 in patients with acute spinal cord injury.

"This marks the beginning of what is potentially a new chapter in medical therapeutics - one that reaches beyond pills to a new level of healing: the restoration of organ and tissue function achieved by the injection of healthy replacement cells," said Geron's president and CEO.

Japan' has warned the Mount Asama volcano could erupt within 48 hours Photo: Reuters

From The Telegraph:

Tens of thousands of people living near Japan's volatile Mount Asama have been told to brace themselves for a major volcanic eruption within 48 hours.

The volcano is one of Japan's most active and last erupted in September 2004 when molten rock and ash blanketed areas more than 125 miles from the crater.

Even by Japanese standards, Mount Asama is an active volcano, with frequent bouts of activity over recent years. The most famous eruption came in 1783 and caused the deaths of more than 1,500 people and widespread damage.

Japan's Meteorological Agency yesterday raised the alert level for the 8,420ft peak, warning of an imminent eruption and forbidding anyone to scale the mountain.

More than 45,000 nearby residents have been put on alert and told to be ready to leave their homes within two hours notice.

Rubik's Revenge: Cube Inventor Set To Launch 21st Century Version Of Iconic Puzzle

Rubik's 360 (Click On Image To Enlarge)

From The Daily Telegraph:

For a few years the Rubik's Cube had millions under its spell.

Umpteen hours were spent on the infuriating device, which became the fastest selling puzzle of all time.

Eventually of course, more and more discovered the secret of how to solve it and word spread that youngsters were cracking the Cube in as little as eight seconds.

To the inventor, Professor Erno Rubik, this was merely the challenge to create something even more difficult.

And he appears to have done just that with the Rubik's 360, which is due to be formally unveiled this week.

Using the same formula of an apparently simple task that is maddeningly hard to complete, it involves moving plastic balls through a set of transparent spheres.

Professor Rubik, 64, a reclusive Hungarian, said: 'The 360 is one of the most innovative and exciting puzzles we've developed since the Cube, adopting elements of myoriginal design, challenging the solver to use skill, dexterity and logic.'

Can A Person Be Scared To Death?

Edvard Munch's famous painting: "The Scream"

From Scientific American:

A 79-year-old woman dies in North Carolina after a heart attack brought on by terror.

A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to elude cops after a botched bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into and hid out in the home of Mary Parnell. Police say he didn't touch Parnell but that she died after suffering a heart attack that was triggered by terror. Can the fugitive be held responsible for the woman's death? Prosecutors said that he can under the state's so-called felony murder rule, which allows someone to be charged with murder if he or she causes another person's death while committing or fleeing from a felony crime such as robbery—even if it's unintentional.

But, medically speaking, can someone actually be frightened to death? We asked Martin A. Samuels, chairman of the neurology department at Brigham and Women's Hospital in Boston.

From The Telegraph:

An extinct animal has been brought back to life for the first time after being cloned from frozen tissue.

The Pyrenean ibex, a form of wild mountain goat, was officially declared extinct in 2000 when the last-known animal of its kind was found dead in northern Spain.

Shortly before its death, scientists preserved skin samples of the goat, a subspecies of the Spanish ibex that live in mountain ranges across the country, in liquid nitrogen.

Using DNA taken from these skin samples, the scientists were able to replace the genetic material in eggs from domestic goats, to clone a female Pyrenean ibex, or bucardo as they are known. It is the first time an extinct animal has been cloned.

Too Much TV Linked To Future Fast-food Intake

From Science Daily:

ScienceDaily (Feb. 1, 2009) — High-school kids who watch too much TV are likely to have bad eating habits five years in the future. A new study followed almost 2000 high- and middle-school children and found that TV viewing times predict a poor diet in the future.

Dr Daheia Barr-Anderson worked with a team of researchers from the University of Minnesota to investigate the relationship between television and diet. She said, "To our knowledge, this is the first study to examine the association between television viewing and diet over the transition from adolescence into young adulthood. We've shown that TV viewing during adolescence predicts poorer dietary intake patterns five years later".

From Watts Up With That:

It is generally accepted that CO2 is lagging temperature in Antarctic graphs. To dig further into this subject therefore might seem a waste of time. But the reality is, that these graphs are still widely used as an argument for the global warming hypothesis. But can the CO2-hypothesis be supported in any way using the data of Antarctic ice cores?

At first glance, the CO2 lagging temperature would mean that it’s the temperature that controls CO2 and not vice versa.

With its sea turtles and surf shops, the Big Island of Hawaii resembles a tropical, watery world. Yet for climate scientists, it's the ideal place to study low-humidity air and the processes that dehydrate the atmosphere.

From the sprawling dome of Mauna Loa — 11,000 feet above Hawaii's coconut-fringed beaches — climate scientists David Noone and Joe Galewsky can track water vapor that's traveled as far as the equator and the pole. They're the first to try to measure vapor's chemical signature in real-time in order to understand the processes controlling the global water cycle.

The Tech That Makes The Super Bowl Super

From CNET:

At its core, football represents the polar opposite of technology: A bunch of large men run around a field, battling for position and the control of a small pigskin ball.

Of course, the production of an actual NFL game requires lots of technology--from the headsets coaches use to communicate, to the computers used to calculate statistics to the HD cameras that record the contest for the viewing audience.

When it comes to the Super Bowl, one of the biggest sporting events in the world, technology has always played a very central role, and this year is no exception.

Science May Explain Our Love Of Sports

Super Bowl 42

From Kansas City:

A relatively recent discovery in science may explain our country’s obsession with watching sports — like the expected audience of 90 million or so for today’s Super Bowl.

They call them “mirror neurons,” and they fire in your brain much the same way whether you’re doing something or watching someone else do it. The discovery killed a lot of assumptions scientists had about brain activity.

It explains why you get hungry if you see someone eating a juicy steak, thirsty when you see a cold drink — or excited when you watch sports.

“In a way, your brain is behaving the same way as (the athletes you’re watching),” says Marco Iacoboni, a neuroscientist at UCLA and the author of Mirroring People: The New Science of How We Connect with Others. “Your brain is making the same signals as the athletes you see on the screen, even if you’re just on the sofa eating popcorn.”

Do Huge NFL Players Help Teams Win?

From Live Science:

When the Arizona Cardinals meet the Pittsburgh Steelers in Sunday's Super Bowl, every starting offensive lineman will be a member of the 300-pound club.

This season, there were more than 600 players — about 20 percent of the league — in triple donuts. Even with 6-foot plus heights, their Body Mass Index (BMI) levels are all in the range of grade 2 obesity, one step below what's called morbid obesity.

This super-sizing of NFL players has accelerated in recent years, and some studies suggest health risks are growing. But studies are conflicting on this point.

And the big question on the minds of coaches and owners: Do heavier players mean more wins? No, one study found.

The Physics of ‘The Hit’ -- Superbowl Science

Baltimore running back Willis McGahee was seriously injured after a collision with the Steelers' Ryan Clark in the A.F.C. championship game. Julie Jacobson/Associated Press

From The New York Times:

TAMPA, Fla. — Isaac Newton’s apple hurt considerably less than Ryan Clark’s coconut. But they did have a few things in common.

Clark’s shockingly violent hit on the Baltimore Ravens’ Willis McGahee two Sundays ago — a full-speed, helmet-to-helmet crash that left McGahee unconscious and Clark all but — didn’t just follow the N.F.L.’s rules, but Newton’s as well. Force equaled mass times acceleration. Momentum was conserved. And the bodies finally came to rest, McGahee’s on a stretcher.

“How I look at it, you can be the hammer or the nail,” the inner scientist in Clark explained this week. “I try to be the hammer.”

The tackle, the art of making the ball carrier not stay in motion, is football’s most primeval action. Amusing physicists the way batting averages do actuaries, collisions lead the highlight reels, impart the force of a deadly car crash, and rely upon kinematics that date to a considerably different big bang.

How Ancient Greeks Chose Temple Locations

at Castelvetrano, in Sicily, Italy. Image from Wikipedia

From Live Science:

To honor their gods and goddesses, ancient Greeks often poured blood or wine on the ground as offerings. Now a new study suggests that the soil itself might have had a prominent role in Greek worship, strongly influencing which deities were venerated where.

In a survey of eighty-four Greek temples of the Classical period (480 to 338 B.C.), Gregory J. Retallack of the University of Oregon in Eugene studied the local geology, topography, soil, and vegetation — as well as historical accounts by the likes of Herodotus, Homer, and Plato — in an attempt to answer a seemingly simple question: why are the temples where they are?

No clear pattern emerged until he turned to the gods and goddesses. It was then that he discovered a robust link between the soil on which a temple stood and the deity worshiped there.

AN UPDATED family tree of the animal kingdom could radically change the way we think about the evolution of species.

According to conventional thinking, simple animals, including sponges, jellyfish and corals, evolved step-by-step in a linear fashion into those with more complex bodies, such as mammals.

Now Rob DeSalle of the American Museum of Natural History in New York and his colleagues have challenged this way of thinking.

The team analysed DNA and other molecular evidence across the animal kingdom, including tiny sea creatures called placozoans. They have found that the placozoans are the closest living thing to the ancestor of all animals.

Is Google Broken? -- News Updates On Google's Glitch Today

Google Error Sends Warning Worldwide -- New York Times

Google’s Internet search service malfunctioned for nearly 55 minutes Saturday morning, upending users around the world with search results that carried false safety warnings and Web links that did not work.

The company acknowledged Saturday that all searches produced links with the same warning message: “This site may harm your computer.” Clicking on any of the links led to an error message stating that the desired site could not be reached.

“What happened?” Google explained in its blog. “Very simply, human error.”

Google said it periodically updates its list of sites suspected of carrying dangerous software that could harm computers, and that Saturday morning a Google employee mistyped a Web address for one such site, causing all sites to be flagged harmful.

There was some momentary tension when Google seemed to imply that the glitch was caused by StopBadware.org, the company that helps Google determine which sites are unsafe. Google later posted a statement that took the blame for the error.

Action Sunrise At The Very Large Array

From Live Science:

Astronomers recently used the NSF's Very Large Array (VLA) radio telescope (above) to help find the most distant water yet seen in the Universe, in a galaxy more than 11 billion light-years from Earth. Previously, the most distant water had been seen in a galaxy less than 7 billion light-years from Earth.

The soggy galaxy is dubbed MG J0414+0534. In a region near its core, water molecules are acting as masers, the radio equivalent of lasers, to amplify radio waves at a specific frequency.

The water molecules showed themselves with a tell-tale radio "fingerprint." The first indication came from the giant, 100-meter-diameter radio telescope in Effelsberg, Germany, and scientists confirmed the discovery using the VLA. The astronomers say their finding indicates that such giant, water masers were more common in the early Universe than they are today. MG J0414+0534 is seen as it was when the Universe was roughly one-sixth of its current age.

From Live Science:

Mount Redoubt volcano in Alaska could erupt within days to weeks, say scientists at the U.S. Geological Survey, amazing the rest of us with their certainty.

Here's what makes them so sure: Magma rising toward the surface from beneath a volcano like Redoubt can cause earthquakes and other seismic rumblings. And seismic activity at Redoubt, which is 106 miles (170 km) southwest of Anchorage, has increased recently.

"If you're going to bring magma to the surface you've got to break rock, and every time rocks break at the subsurface beneath a volcano, that's an earthquake," said volcanologist Charles Mandeville of the American Museum of Natural History in New York. "They're recording a whole bunch of earthquakes almost continuously right now," he said, referring to scientists at the Alaska Volcano Observatory in Anchorage.

The Biology Of Dating: Why Him, Why Her?

From Time Magazine:

Ah, the eternal question: why is HE with HER? Biological anthropologist Helen Fisher thinks she has found the answer after studying the academic literature on personality and after poring over 40,000 responses to a questionnaire on an online dating site.

A lot of things influence who we're attracted to, but one thing that has always puzzled scientists is the role that personality plays in mate selection. Have you solved that riddle?
There are two parts of personality. There's character, which is everything you grew up to believe and do and think. And then there's temperament, which is your inherited traits. Some people are more stubborn than others, some are more curious, some are more aggressive. What I'm trying to do is add the role of biology, of temperament, to our human understanding of love.

Rising Acidity Is Threatening Food Web of Oceans, Science Panel Says

From New York Times:

The oceans have long buffered the effects of climate change by absorbing a substantial portion of the greenhouse gas carbon dioxide. But this benefit has a catch: as the gas dissolves, it makes seawater more acidic. Now an international panel of marine scientists says this acidity is accelerating so fast it threatens the survival of coral reefs, shellfish and the marine food web generally.

The panel, comprising 155 scientists from 26 countries and other international groups, is not the first to point to growing ocean acidity as an environmental threat. For example, a group of eminent scientists convened by The Nature Conservancy issued a similar assessment in August. But the new report’s blunt language and international backing give its assessment unusual force. It called for “urgent action” to sharply reduce emissions of carbon dioxide.

Stem Cell Transplant Reverses Early Stage Multiple Sclerosis

From Eureka Alert:

CHICAGO --- Researchers from Northwestern University's Feinberg School of Medicine appear to have reversed the neurological dysfunction of early-stage multiple sclerosis patients by transplanting their own immune stem cells into their bodies and thereby "resetting" their immune systems.

"This is the first time we have turned the tide on this disease," said principal investigator Richard Burt, M.D. chief of immunotherapy for autoimmune diseases at the Feinberg School. The clinical trial was performed at Northwestern Memorial Hospital where Burt holds the same title.

The patients in the small phase I/II trial continued to improve for up to 24 months after the transplantation procedure and then stabilized. They experienced improvements in areas in which they had been affected by multiple sclerosis including walking, ataxia, limb strength, vision and incontinence. The study will be published online January 30 and in the March issue of The Lancet Neurology.

Fight Brews Over How To Build A Better Internet

Switch and Data’s PAIX in Palo Alto is a primary Internet exchange point in North America. (Tony Avelar/The Christian Science Monitor)

From Christian Science Monitor:

The stimulus bill has $6 billion to expand broadband access. But who can do it soonest vs. best?

America, where the Internet was invented, has fallen behind many European and East Asian countries in Internet speed, cost, and reach.

Roughly 10 percent of US households have no access to a high-speed, or broadband, data connection. Barely 3 percent have fiber-optic connections capable of delivering high-speed data that future industries are expected to rely on. While countries like Sweden are wiring themselves up with the next-generation Internet, the US is making do with a network roughly on par with Iceland.

So a $6 billion effort to upgrade America’s Internet – part of the stimulus package Congress is trying to pass – would seem a political slam-dunk. The US stimulates its economy right away with projects that would pay dividends well into the 21st century.

From Scientific American:

Nuclear power--like most forms of electricity generation--carries inherent risks. Is it worth the minor chance of a major catastrophe?

On Feb. 16, 2002, the nuclear power plant called Davis–Besse on the shores of Lake Erie near Toledo, Ohio, shut down. On inspection, a pineapple-size section on the 6.63-inch- (16.84-centimeter-) thick carbon steel lid that holds in the pressurized, fission-heated water in the site's sole reactor had been entirely eaten away by boric acid formed from a leak. The only thing standing between the escape of nuclear steam and a possible chain of events leading to a meltdown was an internal liner of stainless steel just three sixteenths of an inch (0.48 centimeter) thick that had slowly bent out about an eighth of an inch (0.32 centimeter) into the cavity due to the constant 2,200 pound-per–square-inch (155-kilogram-per-square-centimeter) pressure.

What's Happening To The Sun?

The First Cycle 24 Sunspot: NOAA

From Popular Science:

Could its unusual behavior herald a new ice age?

For about 50 years from roughly 1650 to 1700, the Sun took a break from its typical sunspot activity. That phase of solar rest coincided with what we now refer to as "The Little Ice Age" -- a period of cooling on the Earth that resulted in bitterly cold winters, particularly in Europe and North America. Scientists attribute the Little Ice Age to two main causes: increased volcanic activity and reduced solar activity.

Could it happen again? And are we headed there now?

From FOX News:

Still worried that the Large Hadron Collider will create a black hole that will destroy the Earth when it's finally switched on this summer?

Um, well, you may have a point.

Three physicists have reexamined the math surrounding the creation of microscopic black holes in the Switzerland-based LHC, the world's largest particle collider, and determined that they won't simply evaporate in a millisecond as had previously been predicted.

Rather, Roberto Casadio of the University of Bologna in Italy and Sergio Fabi and Benjamin Harms of the University of Alabama say mini black holes could exist for much longer — perhaps even more than a second, a relative eternity in particle colliders, where most objects decay much faster.

Fringe Fact v. Fiction: Could Your Brain Actually Turn to Goo?

From Popular Mechanics:

In its 12th episode, Fringe brought back one of the all-time greatest, grossest sci-fi horrors: Liquefied brains.

While investigating a string of murders, the agents find viscous liquid oozing from victims' orifices–something has turned their brains into nothing but goo. Sure enough, drilling a hole into a victim sends brown goo, all that's remaining of his brain, dripping out of his skull. "The brain goo that they made is maybe the most disgusting thing I've ever seen," Fringe star Joshua Jackson said in a promo for last night's episode, "The No-Brainer." But is the brain science as far off the mark as it has been in past episodes?

Staying Afloat -- Treading Water In A Sea of Data

From The New Atlantis:

In March 1997, Wired magazine, ever the zealous prophet of near-future consumer tech, breathlessly trumpeted the imminent death of the Internet browser and the rise of so-called “push media.” In short, the idea was that the Web would expand beyond the confines of the browser, both to additional desktop applications and to a host of other devices: phones, televisions, appliances, and even wallpaper. Next, all of these devices would coordinate their information delivery, transforming the Web from a passive medium, in which users request information, to an active medium, in which information “pushes” itself toward users. This new medium, we learn, would not “wait for clicks”: it’s “always-on, mildly in-your-face” and will “bombard you with an intensity that invitational media never muster.” Content, we are promised—or warned?—“will not hesitate to find you.”

The Workings Of An Ancient Nuclear Reactor

Uranium ore.
United States Geological Survey and the Mineral Information Institute

From Scientific American:

Two billion years ago parts of an African uranium deposit spontaneously underwent nuclear fission. The details of this remarkable phenomenon are just now becoming clear.

In May 1972 a worker at a nuclear fuel–processing plant in France noticed something suspicious. He had been conducting a routine analysis of uranium derived from a seemingly ordinary source of ore. As is the case with all natural uranium, the material under study contained three isotopes— that is to say, three forms with differing atomic masses: uranium 238, the most abundant variety; uranium 234, the rarest; and uranium 235, the isotope that is coveted because it can sustain a nuclear chain reaction. Elsewhere in the earth’s crust, on the moon and even in meteorites, uranium 235 atoms make up 0.720 percent of the total. But in these samples, which came from the Oklo deposit in Gabon (a former French colony in west equatorial Africa), uranium 235 constituted just 0.717 percent. That tiny discrepancy was enough to alert French scientists that something strange had happened. Further analyses showed that ore from at least one part of the mine was far short on uranium 235: some 200 kilograms appeared to be missing— enough to make half a dozen or so nuclear bombs.

Mars Rover Disoriented Somewhat After Glitch

Nasa's Spirit

From The New York Times:

On the 1,800th Martian day of its mission, NASA’s Spirit rover blanked out, and it remains a bit disoriented.

Mission managers at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., reported Wednesday that the Spirit had behaved oddly on Sunday — the 1,800th Sol, or Martian day, since Spirit’s landing on Mars in January 2004.

(A Martian Sol is 39.5 minutes longer than an Earth day. The Spirit and its twin, the Opportunity, were designed to last just 90 Sols each, but both continue to operate more than five years later.)

Ten Sci-Fi Devices That Could Soon Be In Your Hands

The briefcase-sized Prism 200 from UK firm Cambridge Consultants can detect people through brick walls by firing off pulses of ultra-wideband radar and listening for returning echoes. According to the company, these pulses can pass through building materials over 40 centimetres thick, and spot activity over a range of up to 15 metres. (Image: Cambridge Consultants)

From The New Scientist:

Cast your mind back 30 years, if you are old enough, and you may just remember a rather humdrum, though retrospectively momentous, event. In 1979, the Japanese firm NET launched the first cellular phone network in Tokyo.

For decades the objects remained toys of the super-rich. Who would have thought that today there would be enough cellphones for half the world's population to have one.

That's not the only recent technological revolution. Would you have dreamed that an entire record collection could one day fit in your pocket? How about a system that helps you communicate and share information across the world instantly?

Crystal-ball gazing is a fraught endeavour, but we've decided to take the plunge. In this special feature, we assess the prospects of 10 of the coolest gadgets that in 30 years' time may change our lives as much - or maybe more - than cellphones, iPods and the internet.

People With Super-Memories Forget Nothing

From Live Science:

Imagine never forgetting anything. Virtue? Curse?

Four people are said to have such "super-memories," including the latest case, a Southern California man who researchers don't plan to identify by name. According to USA Today, the man recalls in detail most days of his life, as well as the day and date of key public events, said researchers Larry Cahill.

The newspaper interviewed Jill Price, another person with a super memory. Price discussed her mind lat year in the book "The Woman Who Can't Forget."

There is much about memory that scientists don't understand. Only this month, in fact, they found that a single brain cell can hold a memory for a brief period before it's put in long-term storage, a feat that requires connections between brain cells.

Six Biggest Mysteries Of Our Solar System

So far as we know, our solar system is unique in the universe (Image: Nigel Hawtin)

From The New Scientist:

ONCE upon a time, 4.6 billion years ago, something was brewing in an unremarkable backwater of the Milky Way. The ragbag of stuff that suffuses the inconsequential, in-between bits of all galaxies - hydrogen and helium gas with just a sprinkling of solid dust - had begun to condense and form molecules. Unable to resist its own weight, part of this newly formed molecular cloud collapsed in on itself. In the ensuing heat and confusion, a star was born - our sun.

We don't know exactly what kick-started this process. Perhaps, with pleasing symmetry, it was the shock wave from the explosive death throes of a nearby star. It was not, at any rate, a particularly unusual event. It had happened countless times since the Milky Way itself came into existence about 13 billion years ago, and in our telescopes we can see it still going on in distant parts of our galaxy today. As stars go, the sun is nothing out of the ordinary.

Astronomers Get A Sizzling Weather Report From A Distant Planet

From E! Science News:

Astronomers have observed the intense heating of a distant planet as it swung close to its parent star, providing important clues to the atmospheric properties of the planet. The observations enabled astronomers at the University of California, Santa Cruz, to generate realistic images of the planet by feeding the data into computer simulations of the planet's atmosphere. "We can't get a direct image of the planet, but we can deduce what it would look like if you were there. The ability to go beyond an artist's interpretation and do realistic simulations of what you would actually see is very exciting," said Gregory Laughlin, professor of astronomy and astrophysics at UCSC. Laughlin is lead author of a new report on the findings published this week in Nature.

The researchers used NASA's Spitzer Space Telescope to obtain infrared measurements of the heat emanating from the planet as it whipped behind and close to its star. In just six hours, the planet's temperature rose from 800 to 1,500 Kelvin (980 to 2,240 degrees Fahrenheit).

Ancient Meteorites Reveal Early Magnetic Fields

From Earth Magazine:

Even before the birth of the planets, our solar system was hardly a lonely place. Small rocky bodies, called planetesimals, filled the inner solar system, eventually colliding together to form the planets. Now a new look at a group of ancient meteorites shows that at least some planetesimals generated their own magnetic fields — a feat many scientists thought extremely difficult for such small astronomical bodies. The work also has scientists rethinking how planets formed.

Most meteorites don’t make it to Earth unscathed. After repeatedly smashing into other objects and traveling through Earth’s harsh atmosphere, they can be substantially altered before crash-landing on the planet. But not angrites — a group of 12 stony meteorites that, at an age of about 4.56 billion years old, are among the oldest-known rocks in the solar system and somehow “got here without being messed up,” says Benjamin Weiss, a planetary geologist at MIT in Cambridge, Mass. Because these meteorites are pristine, angrites retain information about the larger body from which they came.

Danube Delta Holds Answers To 'Noah's Flood' Debate

Giosan and his colleagues estimate that the Black Sea was around 30 meters below present day levels (Black Lake is represented by dark blue water) before a breach of the Bosporus sill 9,500 years ago raised levels to a maximum of 20 meters |(the flooded area is represented by light blue water). Their estimates mean that the magnitude of the Black Sea flood was 5 or 10 meters but not 50 to 60 meters. (Credit: Jack Cook, Woods Hole Oceanographic Institution)

From Science Daily:

ScienceDaily (Jan. 27, 2009) — Did a catastrophic flood of biblical proportions drown the shores of the Black Sea 9,500 years ago, wiping out early Neolithic settlements around its perimeter? A geologist with the Woods Hole Oceanographic Institution (WHOI) and two Romanian colleagues report in the January issue of Quaternary Science Reviews that, if the flood occurred at all, it was much smaller than previously proposed by other researchers.

Using sediment cores from the delta of the Danube River, which empties into the Black Sea, the researchers determined sea level was approximately 30 meters below present levels—rather than the 80 meters others hypothesized.

Alcohol Makes Men BETTER In The Bedroom, Scientists Claim

Drinking effects: A study has suggested that alcohol improves rather than damages
a man's performance in the bedroom

From The Daily Mail:

Men who worry about the effect drinking has on their sex life should raise a glass to the latest research.

Alcohol actually improves rather than damages male performance in the bedroom, it is claimed.

Until now it has been widely believed that alcohol consumption can cause erectile dysfunction, or 'brewer's droop'.

But a study of 1,580 Australian men found drinkers reporting up to 30 per cent fewer problems than teetotallers.

Study: Gamblers Who Lose Bet More

From Live Science:

People who carefully budget their bets before they hit the casinos — say setting a betting limit of $200 per day — routinely go against their plan when they lose.

University of California marketing professors Eduardo Andrade and Ganesh Lyer found that experiencing the pain of actual loss often results in people abandoning their plans and betting more money. "When gamblers haven't experience the actual pain of loss, they make cold and deliberate assessments of how much to bet in case of a future loss," Andrade said.

From Yahoo News/AFP:

WASHINGTON (AFP) – Climate change is "largely irreversible" for the next 1,000 years even if carbon dioxide (CO2) emissions could be abruptly halted, according to a new study led by the US National Oceanic and Atmospheric Administration (NOAA).

The study's authors said there was "no going back" after the report showed that changes in surface temperature, rainfall and sea level are "largely irreversible for more than 1,000 years after CO2 emissions are completely stopped."

NOAA senior scientist Susan Solomon said the study, published in this week's Proceedings of the National Academy of Sciences journal, showed that current human choices on carbon dioxide emissions are set to "irreversibly change the planet."

Climate Change Could Choke Oceans For 100,000 Years

From Wired News:

According to a simulation of planetary warming trends, failure to drastically cut greenhouse gas pollution within the next half century could choke Earth's oceans for the next 100,000 years.

With warmer temperatures reducing its ability to absorb oxygen, much of the water would become barren and lifeless. Oceanic food chains could be profoundly disrupted.

"What mankind does for the next several decades will play a large role in climate on Earth over the next tens of thousands of years," said geochemist Gary Shaffer of the University of Copenhagen.

This is because, according to climate scientists, it will take at least that long for natural processes to remove fossil fuel emissions from the atmosphere, giving long-term consequences to humanity's short-term habits.
