Happy Birthday, Doomsday Seed Vault!

The Entrance to the Vault: Mari Tefre/Global Crop Diversity Trust

From Popsci.com:

The Svalbard Global Seed Vault, designed to preserve the world's crops, turns one year old today

What do you get a seed bank for its birthday? More seeds, of course.

The Svalbard Global Seed Vault celebrates its first birthday today with the addition of 90,000 seed samples. The vault serves as a heavy-duty backup for gene banks around the world, which strive to save humanity (and our food supply) from the scourges of monoculture and environmental catastrophes.

The Norwegian government meant business when it built the vault. They tunneled 400 feet into an Arctic mountain to protect the pips, which are guarded behind two security doors and two airlocks. The underground vault is designed to weather just about every doomsday scenario, including terrorists, nuclear war, and floods of biblical proportions. It was featured in an award-winning low-budget science fiction film last year: "Frozen Seed."

From Science News:

A new way to process images reveals an extrasolar planet that had been hiding in an 11-year-old Hubble picture

Like tiny jewels not yet uncovered, a trove of previously unknown extrasolar planets — perhaps as many as 100 — await discovery in a vast archive of images taken by the Hubble Space Telescope, the results of a new search technique suggest.

Using the new method, astronomers can more precisely model the amount and distribution of scattered light produced by young nearby stars suspected of spawning planets, and then subtract the light from images of those stars. Once the glare of the light from the parent stars is removed, young Jupiter-mass planets that emit faint but detectable amounts of heat may show up in images already taken by Hubble’s near-infrared camera.

Lifestyle Changes Could Prevent A Third Of Cancers: Report

From The CBC News:

An ounce of prevention is worth more than a pound of cure when it comes to cancer, according to an exhaustive international report.

The report by the American Institute for Cancer Research and the World Cancer Research Fund was released Thursday in London, England.

It calls on governments to legislate healthy living, such as:

* Mandate walking and cycling paths that encourage physical activity.
* Support policies for better-priced, healthier food choices for consumers, such as reformulating processed foods to have less sugar, salt and fat.
* Ban ads for sugary drinks and unhealthy foods aimed at children.
* Require schools to provide built-in exercise opportunities for children.

Carbon Dioxide Drop And Global Cooling Caused Antarctic Glacier To Form

Projection of the what the first Antarctic ice sheet might have looked like as the global climate cooled about 33.5 million years ago. Antarctica is in gray, with the ice sheet shown in meters of ice thickness. The ice sheet is continental in scale, but somewhat smaller than today. The estimate is based on prior modeling work of DeConto and Pollard and is supported by this new data study. (Credit: DeConto & Pollard / Nature)

From Science Daily:

ScienceDaily (Feb. 27, 2009) — Global climate rapidly shifted from a relatively ice-free world to one with massive ice sheets on Antarctica about 34 million years ago. What happened? What changed? A team of scientists led by Yale geologists offers a new perspective on the nature of changing climatic conditions across this greenhouse-to-icehouse transition — one that refutes earlier theories and has important implications for predicting future climate changes.

Detailed in the February 27 issue of Science, their data disproves a long-held idea that massive ice growth in the Antarctic was accompanied by little to no global temperature change.

Remains of embryos entombed in their fish mothers' wombs for 380 million years have been found in fossils from an ancient rock outcrop in Western Australia. The finding is a big deal because it suggests that sex goes way back.

The prehistoric fish, called placoderms, are found at the base of the vertebrate evolutionary tree (in a large group we humans also belong to), so it now looks like sexual intercourse, and the mating behaviors that go along with it, were more widespread in these ancient animals than previously thought, said the scientists who made the discovery.

The Weirdest New Source of Alternative Energy: Underwater Vibrations

A prototype underwater generator shows the fluid dynamics that will produce power from slow-moving currents using metal rods suspending near the ocean or river floor. Image courtesy of NOAA

From Discover Magazine:

Researchers say this longtime bane of offshore drilling is more cost-efficient than wind and solar.

The latest frontier for renewable energy is the ocean floor. A novel method of generating power uses a network of metal rods to tap into the currents that flow along the bottom of the ocean (and along riverbeds as well). Water swirls as it flows past the rods, making them vibrate. This phenomenon is painfully familiar to oil companies, which spend large sums of money minimizing such vibrations in order to stabilize offshore drilling equipment. “Everyone was obsessed with suppressing this motion,” says Michael Bernitsas, the University of Michigan engineer who developed the technology. “At some point it dawned on me that maybe we can do the opposite: Enhance it and harness the energy.”

From Watts Up With That?

The Earth is currently in an interglacial period of an ice age that started about two and a half million years ago. The Earth’s current ice age is primarily caused by Antarctica drifting over the South Pole 30 million years ago. This meant that a large area of the Earth’s surface changed from being very low-albedo ocean to highly reflective ice and snow. The first small glaciers were formed in Antarctica perhaps as long ago as 40 million years. They expanded gradually until, about 20 million years ago, a permanent ice sheet covered the whole Antarctic continent. About 10 million years later, glaciers appeared on the high mountains of Alaska, and about 3 million years ago, ice sheets developed on lower ground in high northerly latitudes.

On the Trail of Osama bin Laden: Scientists Use Biological Tracking Models to Pursue America's Most Wanted

Regional analysis of city islands within a 20-km radius
of bin Laden’s last known location (red dot).

From Popular Mechanics:

The United States military's attempts to track down Osama bin Laden in the seven-plus years since the World Trade Center attacks have been notoriously fruitless. But a new study suggests the way to find America's most wanted criminal is to treat him like an endangered species. In the study, released in MIT International Review, University of California-Los Angeles geographers Thomas Gillespie and John Agnew modeled the terrorist leader's possible whereabouts by using the same techniques conservationists use to track the dispersal of animals and likely migration patterns. Using a variety of criteria specific to Osama bin Laden's needs—electricity, room for his entourage, health problems—the study isolates three buildings in the remote Pakistani town of Parachinar in the Federally Administered Tribal Areas as the most likely hideout. (The paper was submitted to the FBI before it went to the MIT journal and, according the FBI, it was forwarded to the appropriate personnel and is part of an active investigation.)

C.K. Shum, professor of earth sciences at Ohio State University, is part of the international research team that published the map in the February 13 issue of the journal Science.

"The surface can tell us a lot about what's happening inside the Moon, but until now mapping has been very limited," Shum said. "For instance, with this new high-resolution map, we can confirm that there is very little water on the Moon today, even deep in the interior. And we can use that information to think about water on other planets, including Mars."

Unlike Diamonds, Most Minerals Not Forever

From Live Science:

Diamonds may be forever, but that's not true of most minerals. In fact, about two-thirds of the 4,300 known minerals on Earth today owe their existence to biological processes, and thus evolved fairly recently in geological terms. So says Robert M. Hazen of the Carnegie Institution in Washington, D.C., who with seven colleagues identified three phases of mineral evolution.

The first phase began more than 4.55 billion years ago, as the solar system started developing. Chemical elements came together, forming about 250 simple minerals that in turn coalesced into planets. On Earth, the second phase stretched from 4.55 billion to 2.5 billion years ago, starting with the violent collision that formed the Moon. Earth's temperature and pressure varied wildly; plate tectonics began churning the planet's surface; and volatiles appeared, such as water and carbon dioxide, helping to redistribute the elements. Those changes enabled the evolution of some 1,250 new minerals.

Six Ways to Boost Brainpower

Image Composition By Scientific American Mind; Julie Felton Istockphoto (barina); Dean Turner Istockphoto (background)

From Scientific American:

Key Concepts

* Scientists are finding that the adult human brain is far more malleable than they once thought. Your behavior and environment can cause substantial rewiring of your brain or a reorganization of its functions.
* Studies have shown that exercise can improve the brain’s executive skills, which include planning, organizing and multitasking. What you eat can also influence how effectively your brain operates.
* Activities such as listening to music, playing video games and meditating may boost cognitive performance as well.

Amputees sometimes experience phantom limb sensations, feeling pain, itching or other impulses coming from limbs that no longer exist. Neuroscientist Vilayanur S. Ramachandran worked with patients who had so-called phantom limbs, including Tom, a man who had lost one of his arms.

Ramachandran discovered that if he stroked Tom’s face, Tom felt like his missing fingers were also being touched. Each part of the body is represented by a different region of the somatosensory cortex, and, as it happens, the region for the hand is adjacent to the region for the face. The neuroscientist deduced that a remarkable change had taken place in Tom’s somatosensory cortex.

Scientists Close In On 'Universal' Vaccine For Flu: Study

From Breitbart/AFP:

Scientists on Sunday unveiled lab-made human antibodies that can disable several types of influenza, including highly-lethal H5N1 bird flu and the "Spanish Flu" strain that killed tens of millions in 1918.

Tested in mice, the antibodies work by binding to a previously obscure structure in the flu virus which, when blocked, sabotages the pathogen's ability to enter the cell it is trying to infect, according to the study.

Because this structure -- described by one scientist as a "viral Achilles' heel" -- is genetically stable and has resisted mutation over time, the antibodies are effective against many different strains.

CAPE CANAVERAL, Fla. – NASA delayed the launch of space shuttle Discovery for a fourth time on Friday amid valve concerns, and managers are uncertain when the flight will take place.

Following a 13-hour meeting at Kennedy Space Center, shuttle managers decided against launching next week. The launch had been targeted for no sooner than Feb. 27; no new date was set.

Officials said they believe they have a realistic shot at launching Discovery to the international space station before mid-March. After that, the shuttle would have to get in line behind a Russian Soyuz launch with a new space station crew, and the next opportunity for Discovery would be after April 6.

Is Genius Born or Can It Be Learned?

From Time Magazine:

Is it possible to cultivate genius? Could we somehow structure our educational and social life to produce more Einsteins and Mozarts — or, more urgently these days, another Adam Smith or John Maynard Keynes?

How to produce genius is a very old question, one that has occupied philosophers since antiquity. In the modern era, Immanuel Kant and Darwin's cousin Francis Galton wrote extensively about how genius occurs. Last year, pop-sociologist Malcolm Gladwell addressed the subject in his book Outliers: The Story of Success.

From Science Daily:

ScienceDaily (Feb. 22, 2009) — Some algae have been hanging together rather than going it alone much longer than previously thought, according to new research.

Ancestors of Volvox algae made the transition from being a single-celled organism to becoming a multicellular colony at least 200 million years ago, during the Triassic Period.

At that time, Earth was a hot-house world whose inhabitants included tree ferns, dinosaurs and early mammals. Previous estimates had suggested Volvox's ancestors arose only 50 million years ago.

What's An Oscar Really Made Of?

From Live Science:

On Sunday, nominated movie stars will show up at Hollywood’s Kodak Theatre hoping to walk away clutching one of those glowing statuettes. But there's more to that golden guy than meets the eye.

When they pick up their trophies, the winning celebs are toting around 8.5 pounds of metal. Oscar is 13.5 inches (34 centimeters) tall.

The Oscar statuettes, officially dubbed the Academy Award of Merit, have a 24-karat gold plating on their surface.

Beneath the gold, the statuette's interior is a metal mixture called Britannium, also called Britannia metal. It is an alloy of tin (93 percent), antimony (5 percent), and copper (2 percent). It's known for its smooth texture and silvery appearance.

From Wired Science/Reuters:

CHICAGO (Reuters) - Two U.S. teams have developed new materials that may pave the way for ever smaller, faster and more powerful electronics as current semiconductor technology begins to reach the limits of miniaturization.

One team has made tiny transistors -- the building block of computer processors -- a fraction of the size of those used on advanced silicon chips.

Another has made a film material capable of storing data from 250 DVDs onto a surface the size of a coin.

As The World's Languages Disappear, Basque Revives

From McClatchy:

ST. JEAN DE LUZ, France — The world is losing languages at an alarming rate, a United Nations agency reported Thursday, with thousands of tongues expected to disappear by the end of this century.

Yet amid the losses, one community — the Basque people, who live in the mountainous region of southern France and northern Spain — is reviving a language that many once feared would die out.

In St. Jean de Luz, a seaside town near the Spanish border at the western edge of the Pyrenees, efforts are under way to revitalize the Basque language, which 30 years ago was rarely heard outside mountain villages. Among a population of about 3 million in the Basque region, which comprises seven provinces in Spain and France, an estimated 700,000 people speak Basque today.

Bilingual signs dot the roads and mark storefronts, and an annual festival celebrates the Basque language, music and culture. Public and private schools full of children and adults learn Basque.

It's All Systems Go For Europa

Europa, dwarfed by Jupiter, is in the center of this image taken by the Cassini spacecraft on Dec. 7, 2000. "Europa is tremendously exciting," a NASA official said. NASA

From The L.A. Times:

NASA unveils plans for a 20-year project to send a spacecraft to Jupiter's ice-covered moon in a search for life.

NASA announced plans Wednesday to embark on a mammoth 20-year project to send a spacecraft to Jupiter's ice-covered moon Europa as its next flagship mission to search for life elsewhere in the solar system.

The mission, which could cost as much as $3 billion, will be managed by the Jet Propulsion Laboratory in La Cañada Flintridge. It will focus on the possibility that in the gigantic ocean thought to be hidden under the moon's thick cover of ice is a habitable zone where rudimentary forms of life could exist.

Arctic Sea Ice Underestimated For Weeks Due To Faulty Sensor

From Bloomberg:

A glitch in satellite sensors caused scientists to underestimate the extent of Arctic sea ice by 500,000 square kilometers (193,000 square miles), a California- size area, the U.S. National Snow and Ice Data Center said.

The error, due to a problem called “sensor drift,” began in early January and caused a slowly growing underestimation of sea ice extent until mid-February. That’s when “puzzled readers” alerted the NSIDC about data showing ice-covered areas as stretches of open ocean, the Boulder, Colorado-based group said on its Web site.

From FOX News/Space.com:

A recently discovered comet is making its closest approach to Earth in the next few days and offers anyone with binoculars or a small telescope a chance to see some frozen leftovers of our solar system's making.

Comet Lulin has, as expected, crossed the threshold to naked-eye visibility for people with dark, rural skies. It hovers just inside that envelope of visibility, however, and is not likely visible from cities, where the glare of urban lights can drown out all but the brightest night-sky objects.
