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

Photochromic material (Credit: ACS)

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.

64 Things Every Geek Should Know

From Lap Top Logic:

If you consider yourself a geek, or aspire to the honor of geekhood, here's an essential checklist of must-have geek skills.

The term 'geek', once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field. A geek is one who isn't satisfied knowing only the surface facts, but instead has a visceral desire to learn everything possible about a particular subject.

A techie geek is usually one who knows a little about everything, and is thus the person family and friends turn to whenever they have a question. If you're that type of person and are looking for a few extra skills to pick up, or if you're a newbie aiming to get a handhold on the honor that is geekhood, read on to find out what skills you need to know.

From Watts Up With That?

What would NSIDC and our media make of a photo like this if released by the NAVY today? Would we see headlines like “NORTH POLE NOW OPEN WATER”? Or maybe “Global warming melts North Pole”? Perhaps we would. sensationalism is all the rage these days. If it melts it makes headlines.

Some additional captures from the newsreel below show that the ice was pretty thin then, thin enough to assign deckhands to chip it off after surfacing.The newsreel is interesting, here is the transcript.

Who Will Be Tech's Next Winners And Losers?

From Pajamas Media/Edgelings:

Let’s take a moment and try to imagine the U.S. economy when this recession is over.

Needless to say, that’s a big “when”, especially when Washington seems to doing its best to extend this economic downturn as long as possible.

But let’s suppose that there is a sudden outbreak of sanity among our political leaders: they stop driving the nation’s CEOs in defensive postures, they abandon their attempts to destroy entrepreneurship and venture capital, and basically, they stop threatening onerous new taxes and regulations – basically, they just get out of the way – and let the economy finish healing itself.

What happens next? Who will be the big winners, especially in high tech, in the next boom? Here are my guesses:

Epigenetics: A Revolutionary Look At How Humans Work

The epigenome is a molecular marking system that controls gene expression without altering the DNA sequence. In a sense, the epigenome is the genome's boss. Image credit: Dreamstime.

From Live Science:

Scientists are now pinpointing exactly how nurture affects nature. Life experiences — from toxin exposure to physical affection — can alter gene expression in dynamic and sometimes reversible ways.

These insights — the result of a burgeoning field called epigenetics — were aided by the sequencing of the human genome, completed in 2003. However, the genome itself turns out to have limited value for understanding disease and human characteristics.

Single-Molecule Nano-Vehicles Synthesized: 'Fantastic Voyage' Not So Far-Fetched

James Tour and coworkers at Rice University synthesized a molecular car with four carbon-based wheels that roll on axles made from linked carbon atoms. The nano-car's molecular wheels are 5,000 times smaller than a human cell. A powerful technique that allows viewing objects at the atomic level called scanning tunneling microscopy reveals the wheels roll perpendicular to the axles, rather than sliding about like a car on ice as the car moves back and forth on a surface. (Credit: Y. Shirai/Rice University)

From Science Daily:

ScienceDaily (Apr. 27, 2009) — Imagine producing vehicles so small they would be about the size of a molecule and powered by engines that run on sugar. To top it off, a penny would buy a million of them.

A new article published in the May 2009 issue of Scientific American asks readers to do just that.

The concept is nearly unthinkable, but it's exactly the kind of thing occupying National Science Foundation supported researchers at Penn State and Rice universities.

Spectacular Cosmic Bubble '60 Light Years Wide And 70,000 Years Old'

Dr Don Goldman took this picture from his base in California Photo: NATIONAL

From The Telegraph:

This spectacular cosmic bubble was caused by a gas expulsion from a dying star and is 60 light years across and 70,000 years old.

At its centre is a star, known as a Wolf-Rayet star which is 20 times the mass of the sun.

When it dies it throws out gas, creating winds which form the bubble.

It will eventually explode into a supernova.

Photographer Dr Don Goldman took this picture remotely from his base in California via an observatory in South Australia.

Dr Goldman said: "The object, known as S308 is a 'cosmic bubble' that represents a last-minute expulsion of gas from a dying star that forms a super wind in the form of a bubble.

G.E.’s Breakthrough Can Put 100 DVDs On A Disc

Brian Lawrence leads G.E.’s holographic storage program.
Nathaniel Brooks for The New York Times

From The New York Times:

General Electric says it has achieved a breakthrough in digital storage technology that will allow standard-size discs to hold the equivalent of 100 DVDs.

The storage advance, which G.E. is announcing on Monday, is just a laboratory success at this stage. The new technology must be made to work in products that can be mass-produced at affordable prices.

But optical storage experts and industry analysts who were told of the development said it held the promise of being a big step forward in digital storage with a wide range of potential uses in commercial, scientific and consumer markets.

James Brewer takes a seat beside me in a café at the San Diego Convention Center, where we are both attending the largest neuroscience meeting in the world: thirty thousand brains researching brains. With his balding head, bright eyes, and baby cheeks, Brewer, a neurologist at the University of California at San Diego, looks like a large and curious toddler. An unlikely messenger, perhaps, in what for me is now a moment of truth. I had undergone a series of diagnostic procedures in his laboratory, and now, inside the laptop he has placed on the table, are the results of my brain tests.

Ancient Corals May Provide Record of Rapid Sea Level Rise

Photo: ANCIENT REEF: The creation of this water park exposed reefs that grew roughly 121,000 years ago, allowing scientists to study sea level rise during that warm period. COURTESY OF PAUL BLANCHON

From Scientific American:

Ancient reefs recently exposed in Mexico show that sea levels can rise by as much as 10 feet in half a century

With Greenland's glaciers melting and on the move while vast ice sheets in Antarctica continue to shatter, the proportion of water in the seas continues to grow. And with the climate at the poles expected to continue to warm rapidly in coming decades, many researchers are trying to determine how much and how quickly sea levels might rise. Now newly excavated reefs in Mexico may have provided an answer: high and fast.

From Science Daily:

ScienceDaily (Apr. 26, 2009) — Two of the most important climate change gases increased last year, according to a preliminary analysis for NOAA’s annual greenhouse gas index, which tracks data from 60 sites around the world.

Researchers measured an additional 16.2 billion tons of carbon dioxide (CO2) — a byproduct of fossil fuel burning — and 12.2 million tons of methane in the atmosphere at the end of December 2008. This increase is despite the global economic downturn, with its decrease in a wide range of activities that depend on fossil fuel use.

Basis For Male Promiscuity Questioned

From Live Science:

Males are promiscuous and females are selective when choosing a mate, biologists have said for decades. But a new study finds it might not be that simple.

The study, published in this month's issue of the journal Trends in Ecology and Evolution, evaluated data on 18 populations – from Pitcairn Islanders to the Dogon of Mali – and found that on average, the variance in the number of children is greater for men than for women. This is about what you'd expect on the basis of long-time theory.

Internet Users 'Could Suffer Brownouts Due To YouTube And iPlayer'

Increased use of video-on-demand websites could hinder the internet's reliability Photo: Bloomberg

From The Telegraph:

Internet users will endure slower and less reliable connections from next year as websites such as YouTube and the BBC's iPlayer cause online traffic to double, experts warn.

Computers will freeze and drop offline with increasing regularity as the web's outdated infrastructure struggles to cope with the surging popularity of bandwidth-hungry video sites, it is claimed.

Analysts are warning that the internet will cease to function as an effective tool of communication – becoming merely an "unreliable toy" for casual users – unless networks are upgraded.

US Declares Public Health Emergency For Swine Flu -- Yahoo News/AP

WASHINGTON – The U.S. is declaring a public health emergency to deal with the emerging new swine flu.

The precautionary step doesn't signal a greater threat to Americans. But it allows the federal and state governments easier access to flu tests and medications.

Homeland Security Secretary Janet Napilotano says roughly 12 million doses of the drug Tamiflu are being released from a federal stockpile so that states can get it if needed.
