Wind Farm's Radar System Stops Birds Getting The Chop

From The Guardian:

Texas claims world first in using Nasa technology to spare migrating species.

It could be considered an air traffic control system for birds who have flown perilously off course. A wind farm in southern Texas, situated on a flight path used by millions of birds each autumn and spring, is pioneering the use of radar technology to avoid deadly collisions between a 2,500lb rotating blade and bird.

US wind farms kill about 7,000 birds a year, according to a recent study. Other studies of individual wind farms suggest a higher toll on bats and birds, which crash into towers, blades, power lines and other installations. Estimates from a single wind farm in Altamont, California showed as many as 1,300 birds of prey killed each year – or about three a day.

From The Christian Science Monitor:

Wave power and tidal power are still experimental, but may be little more than five years away from commercial development.

Three miles off the craggy, wave-crashing coastline near Humboldt Bay, Calif., deep ocean swells roll through a swath of ocean that is soon to be the site of the nation’s first major wave-power project.

Like other renewable energy technology, ocean power generated by waves, tidal currents, or steady offshore winds has been considered full of promise yet perennially years from reaching full-blown commercial development.

Ancient Tsunami 'Hit New York'

From The BBC:

A huge wave crashed into the New York City region 2,300 years ago, dumping sediment and shells across Long Island and New Jersey and casting wood debris far up the Hudson River.

The scenario, proposed by scientists, is undergoing further examination to verify radiocarbon dates and to rule out other causes of the upheaval.

Sedimentary deposits from more than 20 cores in New York and New Jersey indicate that some sort of violent force swept the Northeast coastal region in 300BC.

American Epidemics, a Brief History

(Click the Above Image to Enlarge)

From The New York Times:

ALL epidemics are different in their own way, and the current swine flu outbreak — which by Friday had sickened 141 people in 19 states, and caused deaths and illness in Mexico and 13 other countries — is no exception. Yet, as you can see from the chart below, which provides details on a selected handful of epidemics in American history, all outbreaks share certain themes. While some of these events killed many thousands and others affected only a few, in each case public health officials felt a grave threat was imminent and did what they could using the science of the day.

Meet The Ancestors: DNA Study Pinpoints Namibia As Home To The World's Most Ancient Race

The San people, hunter-gatherers in south-west Africa for thousands of years, are believed to be the oldest population of humans on Earth

From The Daily Mail:

Scientists have long known that humans originated in Africa, but now a groundbreaking DNA study has revealed our 'Garden of Eden' is likely to be on the South African-Namibian border.

For it is the San people, hunter-gatherers in this area for thousands of years, who researchers now believe are the oldest human population on Earth.

They are descended from the earliest human ancestors from which all other groups of Africans stem and, in turn, to the people who left the continent to populate other corners of the planet.

From New Scientist:

Probably - for now. The internet is a disparate mix of interconnected computers, many of them on large networks run by universities, businesses and so on. What unites this network of networks are the communication languages known as the Transmission Control Protocol and the Internet Protocol, collectively TCP/IP.

There are also a few large networks that use different protocols and which remain largely isolated from the internet, including something called FidoNet, which links bulletin board systems via the global telephone network, as well as a handful of military networks. The main internet is the only one of any significant size, as far as we know.

Satellite Images Used To Create Better Camouflage

Images gathered from cameras on drones and satellites are used to make a mesh that serves as camouflage for military vehicles. The product, Photo-Veil is from Military Wraps.

From Live Science:

The art of concealing troops and their vehicles has come a long way from the first "camouflage" division formed in France in 1915. The French army called in artists to help prepare colors and designs; the Americans later used the same idea, calling on artists like Grant Wood, the painter of the "American Gothic."

Today, Photo-Veil from Military Wraps is a mesh material that uses images gathered from cameras on drones and satellites to camouflage military vehicles. The lightweight, customizable, foldable, portable and waterproof mesh material is also able to mask thermal and infrared output, making it ideal for blinds and ghillie suits. (At least until your invisibility cloak is ready.)

From Science Daily:

ScienceDaily (May 3, 2009) — Ultrafast, light-sensitive video cameras are needed for observing high-speed events such as shockwaves, communication between living cells, neural activity, laser surgery and elements of blood analysis. To catch such elusive moments, a camera must be able to capture millions or billions of images continuously with a very high frame rate. Conventional cameras are simply not up to the task.

Now, researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a novel, continuously running camera that captures images roughly a thousand times faster than any existing conventional camera.

From Scientific American:

Swine flu has yet to escalate into a global pandemic, but here's what to do if it does.

Experts say that the steps you should take to shield yourself from swine flu are not much different than those you might take to ward off seasonal flu.

1. Don't touch your face
Above all, keep your hands away from your eyes, mouth and nose, all of which serve as pathways for the virus to enter your respiratory tract, says Allison Aiello, an epidemiologist at the University of Michigan School of Public Health in Ann Arbor.

Pictured: The Baby Mammoth Who Went Back To The Deep Freeze To Stop Her Thawing Out

Urgent action: Scientists carried the 3ft mammoth out of the lab and back to the snow. Thanks to this, she remains the best preserved specimen of her kind

From The Daily Mail:

For 40,000 years, she had been perfectly preserved in the icy earth.

But as scientists examined this baby mammoth hoping to unlock her ancient secrets, there was a rather urgent complication.

She began to thaw. They then came up with a somewhat unscientific solution - they carried her out of the lab and into the snow.

Thanks to their swift action, the 3ft mammoth, discovered by reindeer herders in the Russian Arctic, remains the best preserved specimen of her kind.

Discovered in 2007, she is thought to have died in a mudslide at a month old.

The mud effectively ‘pickled’ the baby, who has been named Lyuba, preserving her in a nearly pristine state.

It's unfocused, random, and extremely good at what it does. How we can learn from a baby's brain.

WHAT IS IT like to be a baby? For centuries, this question would have seemed absurd: behind that adorable facade was a mostly empty head. A baby, after all, is missing most of the capabilities that define the human mind, such as language and the ability to reason. Rene Descartes argued that the young child was entirely bound by sensation, hopelessly trapped in the confusing rush of the here and now. A newborn, in this sense, is just a lump of need, a bundle of reflexes that can only eat and cry. To think like a baby is to not think at all.

Mechanisms Of Self-Control Pinpointed In Brain

This 3-D projection of a transparent brain shows the regions of activation: the ventral medial prefrontal cortex (vmPFC) is in red, and the dorsolateral prefrontal cortex (DLPFC) is in green. Activity in the vmPFC reflects the value assigned to foods during decision-making. When self-control is exercised, DLPFC activity increases and appears to interact with the activity in the vmPFC to increase the influence of health considerations. (Credit: Caltech/Todd Hare)

From Science Daily:

ScienceDaily (May 1, 2009) — When you're on a diet, deciding to skip your favorite calorie-laden foods and eat something healthier takes a whole lot of self-control--an ability that seems to come easier to some of us than others. Now, scientists from the California Institute of Technology (Caltech) have uncovered differences in the brains of people who are able to exercise self-control versus those who find it almost impossible.

The key? While everyone uses the same single area of the brain to make these sorts of value-laden decisions, a second brain region modulates the activity of the first region in people with good self-control, allowing them to weigh more abstract factors--healthiness, for example--in addition to basic desires such as taste to make a better overall choice.

From Live Science:

And it really bothers us. "Many people, perhaps most, hate the idea that life might depend on chance processes," writes biologist Dave Deamer on his blog.

Scientists have hypothesized that it started around hot vents on the seafloor, or that things heated up between the mica sheets, or that it came in a comet (which doesn't really solve the origin problem). But nobody knows.

Those who promote intelligent design — an attack on the theory of evolution thought by many scientists to be a thinly veiled effort to get religious ideas into science classrooms — suggest the the astronomical odds of it point to a designer being involved, rather than pure chance.

Still 10-15 Years to Commercialize 10+ Megawatt Superconducting Wind Turbines

From The Next Big Picture:

AMSC (American Superconductor and Texas-based TECO-Westinghouse Motor Co have been working an estimated $6.8 million project to design components for a 10-MW HTS generator. Another HTS device manufacturer, Germany’s Zenergy Power Group, is working with Converteam Ltd in the UK to commercialize an 8-MW HTS wind-turbine generator. Because of the practical limitations to erecting large turbines, a generator’s size and weight do matter, says Larry Masur, a Zenergy vice president. Several groups expect to have generator prototypes ready for testing within two years but commercialization will take 10-15 years to get competitive costs. Kite generated wind and other alternatives to turbines seem like the better approach.

The exploding internet 2008

From New Scientist:

"The mind seemed to grow giddy by looking so far into the abyss of time," said the 18th-century scientist John Playfair, recalling the moment he learned of the Earth's long history. If Playfair could peer into the depths of the internet he might get that giddy feeling again. In 2005, Google estimated the internet contained some 5 million terabytes of data - that's more than 1 gigabyte for each of Earth's 4.5 billion trips around the sun.

There are simpler ways to appreciate the internet's sheer scale. Recent estimates suggest that well over 1 billion people rely on computers to access the internet (see graphics of internet traffic in 2002, 2004, 2006 and 2008). Yet there are also a billion or so other people who use cellphones to visit cyberspace, making them as much a part of the online community as someone surfing from a PC.

Magic And The Brain: Teller Reveals The Neuroscience Of Illusion

From Wired News:

One of the first tricks in Penn and Teller's Las Vegas show begins when Teller—the short, quiet one—strolls onstage with a lit cigarette, inhales, drops it to the floor, and stamps it out. Then he takes another cigarette from his suit pocket and lights it.

No magic there, right? But then Teller pivots so the audience can see him from the other side. He goes through the same set of motions, except this time everything is different: Much of what just transpired, the audience now perceives, was a charade, a carefully orchestrated stack of lies. He doesn't stamp out the first cigarette—he palms it, then puts it in his ear. There is no second cigarette; it's a pencil stub. The smoke from the first butt is real, but the lighter used on the pencil is actually a flashlight. Yet the illusion is executed so perfectly that every step looks real, even when you're shown that it is not.

'Worst-Case' Scenario For Flu Estimated

This map shows the projected number of H1N1 "swine flu" cases in the United States at the county level, 28 days from now. Credit: Christian Thiemann, Rafael Brune, and Alejandro Morales Gallardo/Northwestern University

For Live Science:

There will be about 1,700 U.S. cases of the new H1N1 flu, aka "swine flu," in the next four weeks under a worst-case scenario, according to a research team's new simulations.

And a second team working independently, about 200 miles away, on exactly the same question came up with a similar forecast.

As of Thursday, there were 109 lab-confirmed U.S. cases of the new influenza, according to the World Health Organization, which earlier this week raised the risk level of the influenza to one stage below pandemic because the virus is being transmitted within at least two countries in one region of the world. A full pandemic — the virus is also being transmitted within a third country in a different region — is considered imminent.

From Technology Review:

Researchers make cells with near-perfect internal efficiency.

Plastic solar cells are lightweight, flexible, and, most important, cheap to make. But so far, these devices have been too inefficient to compete with silicon solar cells for most applications. Now researchers from a few institutions claim to have made polymer solar cells with record-breaking efficiencies. These cells still aren't good enough to compete with silicon, but polymer efficiencies have been increasing at a rate of about 1 percent a year. If they can keep this up, say researchers, plastic solar cells will be competing with silicon within a few years.

How To Wake Up Slumbering Minds

From The Wall Street Journal:

Will the discoveries of neuroscientists help us to think, learn and remember?

We are in the midst of an explosion of knowledge about how the human mind and brain work -- how memory comes in many different types, each stored in a different part of the brain; how our minds constantly process information outside our conscious awareness; how differences in brain function help to define differences in our personalities. A lot of this new knowledge raises provocative questions, not least about human nature.

But as disgruntled students have been saying for ages: How are we ever going to use this stuff? Chemistry can boast of miracle drugs, and genetics has done wonders for our food supply and for medical diagnosis. What about psychology and neuroscience? Shouldn't research on learning and memory and thinking help us to learn, remember and think better?

SEA ice around Antarctica has been increasing at a rate of 100,000sq km a decade since the 1970s, according to a landmark study to be published today.

The study by the British Antarctic Survey, published in the journal Geophysical Research Letters, says rather than melting as a result of global warming, Antarctica continues to expand.

The fact that Antarctic ice is still growing does not in itself prove that global warming is not happening. But the BAS says increased ice formation can be explained by another environmental concern, the hole in the ozone layer, which is affecting local weather conditions.

10 Deadly Diseases That Hopped Across Species

From Live Science:

Bacteria and viruses that are deadly to one type of creature can evolve quickly to infect another. While the swine flu outbreak is the latest example, a host of infectious and deadly diseases have hopped from animals to humans and from humans to animals.

The cross-species infection can originate on farms or markets, where conditions foster mixing of pathogens, giving them opportunities to swap genes and gear up to kill previously foreign hosts (i.e. you). Or the transfer can occur from such seemingly benign activities as letting a performance monkey on some Indonesian street corner climb on your head. Microbes of two varieties can even gather in your gut, do some viral dancing, and evolve to morph you into a deadly, contagious host.

Russia Mulls Rocket Power 'First'

The future Russian capsule could land on a bright rocket plume

The BBC:

Russia's next-generation manned space vehicle might be equipped with thrusters to perform a precision landing on its return to Earth.

Engineers are considering a rocket-powered landing system for the successor to Russia's Soyuz spacecraft.

If accepted, it would be the first time in history that a manned vehicle relied solely on rocket engines for touchdown.

Previous manned missions have landed on Earth using a parachute or, in the case of space shuttles, a pair of wings.

RKK Energia, Russia's prime developer of manned spacecraft, had to examine the feasibility of the rocket-powered landing as a result of conflicting requirements for the project set by the Russian government.

Is Swine Flu Pandemic Imminent?

PRECAUTIONS Dozens of deaths have occurred from the swine influenza outbreak in Mexico. People wore surgical masks on Monday in Mexico City. Gregory Bull/Associated Press

From Live Science:

The swine flu drama is advancing like wildfire, with the Mexican death count rising steadily, U.S. cases doubling, and the World Health Organization moving a step closer late Monday to declaring the incident a full-on pandemic.

Will this flu become a global pandemic in humans, like AIDS or the "Spanish flu" of 1918–1919 which killed an estimated 50 million people in 18 months?

Declaring a pandemic is a big official deal. It's the more global version of an epidemic, which is a disease outbreak in a specific community or region or population. The word "pandemic" has a specific meaning to doctors and researchers, and once officials apply it to an outbreak, even more money and other resources are rushed to victims. Not to mention that there hasn't been a flu pandemic in more than 40 years (the "Hong Kong flu").

ScienceDaily (Apr. 29, 2009) — An international team of researchers has determined key structural features of the largest known virus, findings that could help scientists studying how the simplest life evolved and whether the unusual virus causes any human diseases.

The mimivirus has been called a possible "missing link" between viruses and living cells. It was discovered accidentally by French scientists in 1992 but wasn't confirmed to be a virus until 2003.

Edge Of The Universe: Death Throes Of Dying Star Spotted 13 Billion Light Years Away

An artist's impression of a dying star exploding to produce a gamma ray burst.

From The Daily Mail:

Astronomers have snapped a picture of the most distant object ever seen in the universe - a titanic burst of energy from a dying star 13 billion light years away.

The 'gamma ray burst' is so far away that its light has taken almost the entire age of the universe to reach us.

When the light began its journey, travelling at 186,000 miles per second, only 640 million years had passed since the Big Bang that marked the dawn of creation.

As Swine Flu Spreads, Focus Shifts To A Potential Vaccine

From Discover Magazine:

As the swine flu outbreak continues to spread, with Russia, South Korea, and Australia joining the list of countries with suspected cases and the death toll climbing in Mexico, attention has turned to the potential of a swine flu vaccine that could protect populations from infection. But a new vaccine takes some months to develop. Says Iain Stephenson, an expert on flu vaccines: “We are in a position where if a swine flu virus becomes a pandemic we don’t currently have a vaccine for it…. I think that it is unlikely there will be widespread vaccine in less than six to eight months” [Telegraph]. In the meantime, says Stephenson, patients can be treated with antiviral drugs.

How Hackers Can Steal Secrets From Reflections

From Scientific American:

Through the eyepiece of Michael Backes’s small Celestron telescope, the 18-point letters on the laptop screen at the end of the hall look nearly as clear as if the notebook computer were on my lap. I do a double take. Not only is the laptop 10 meters (33 feet) down the corridor, it faces away from the telescope. The image that seems so legible is a reflection off a glass teapot on a nearby table. In experiments here at his laboratory at Saarland University in Germany, Backes has discovered that an alarmingly wide range of objects can bounce secrets right off our screens and into an eavesdropper’s camera. Spectacles work just fine, as do coffee cups, plastic bottles, metal jewelry—even, in his most recent work, the eyeballs of the computer user. The mere act of viewing information can give it away.

From Popsci.com:

A new set of chips gives super-slim cellphones the power of laptops.

Think of Toshiba's TG01 cellphone as the world's smallest PC. It powers 3-D games, plays high-definition movies, and smoothly runs many programs at once, a combo few other phones offer. Yet it's less than four tenths of an inch thick — 20 percent thinner than an iPhone — thanks to Qualcomm's Snapdragon system, which packs several previously separate chips into one case the size of a dime.

From ABC News:

New Research Merges Man and Machine With Stunning Results.

Technology usually changes the way we do things.

We communicate and think differently because of computers. We live differently because planes, trains and automobiles let us travel with ease. We solve hard math problems and physics mysteries because computers let us crunch numbers on a previously impossible scale. The list goes on.

However, every so often -- actually much more often than we, at first, recognize -- technology also upends the way we think about elements of our everyday lives.

Presto! Fast Color-Changing Material May Lead To Improved Sunglasses

From Science Daily:

ScienceDaily (Apr. 28, 2009) — Researchers in Japan are reporting development of a new so-called "photochromic" material that changes color thousands of times faster than conventional materials when exposed to light. The development could lead to a wide range of new products including improved sunglasses, more powerful computers, dynamic holograms, and better medicines, the researchers say.

In the new study, Jiro Abe and colleagues note that photochromic materials are most familiar as the invisible layers found in the lenses of many high-end sunglasses, which change color when exposed to sunlight. For years, researchers have explored the possibility of using these unusual materials for optical data storage in computers and as "molecular switches" for more controlled drug delivery. Conventional photochromic materials, however, tend to be relatively slow-acting (tens of seconds to hours) and unstable, which prevents their use for many advanced applications, the scientists say.

From Live Science:

A vaccine for the new swine flu in humans could take at least six months to manufacture and distribute widely, a British doctor said.

The reason: Vaccines must be developed from the specific flu strain, tested for safety, sent to manufacturers for mass production, and then distributed around the world. By the time this is done, the first wave of a pandemic flu might already be over, said Iain Stephenson, a doctor in the Infectious Diseases Unit of the Leicester Royal Infirmary in England.

Bang Goes That Theory: Dinosaur Extinction 'Occurred 300,000 Years AFTER Asteroid Impact '

Photo: A giant asteroid hit the Earth around 65million years ago, but experts dispute the impact it had

From The Daily Mail:

The popular theory that dinosaurs were wiped out by an asteroid 65million years ago has been challenged.

It was believed the Chicxulub crater in Mexico was the 'smoking gun' of the mass extinction event.

Molten droplets from the ancient asteroid impact were found just below the Cretaceous-Tertiary boundary - a geological layer of sediment linked with the extinction.

But soil samples from the 112-mile wide crater show the impact predates the disappearance of the dinosaurs by about 300,000 years.

The latest research has been published in the Journal of the Geological Society.

From The Telegraph:

A pill that could make memories "stick" is being developed by scientists in a study that could help students revising for exams and patients with brain disorders such as Alzheimer's disease.

Researchers, looking into obesity, discovered that fatty foods not only send feelings of fullness to the brain but they also trigger a process that consolidates long term memories.

It believed that this is an evolutionary tool that enabled our distant ancestors to remember where rich sources of food were located.
