5 Nanometer Computer Chips

From Future Pundit:

While Moore's Law for increasing computer chip transistor density won't go on for more than another 20 years it is still happening. Intel introduced 32 nanometer chips in 2009 and will introduce 22 nm chips in 2011. The New York Times reports on Rice University and Hewlett-Packard researchers who have developed 5 nanometer logic devices.

These chips store only 1,000 bits of data, but if the new technology fulfills the promise its inventors see, single chips that store as much as today’s highest capacity disk drives could be possible in five years. The new method involves filaments as thin as five nanometers in width — thinner than what the industry hopes to achieve by the end of the decade using standard techniques. The initial discovery was made by Jun Yao, a graduate researcher at Rice. Mr. Yao said he stumbled on the switch by accident.

What Is Consciousness?

From Think Big:

What does it mean to be conscious? It's a question that philosophers and scientists have puzzled over perhaps since there have been philosophers and scientists.

In his book "Consciousness Explained," Tufts University philosopher Daniel Dennett calls human consciousness "just about the last surviving mystery," explaining that a mystery is something that people don't yet know how to think about. "We do not yet have all the answers to any of the questions of cosmology and particle physics, molecular genetics and evolutionary theory, but we do know how to think about them," writes Dennett. "With consciousness, however, we are still in a terrible muddle. Consciousness stands alone today as a topic that often leaves even the most sophisticated thinkers tongue-tied and confused. And, as with all of the earlier mysteries, there are many who insist—and hope—that there will never be a demystification of consciousness."

From The New Scientist:

SOME 16 million years ago, north became south in a matter of years. Such fast flips are impossible, according to models of the Earth's core, but this is now the second time that evidence has been found.

The magnetic poles swap every 300,000 years, a process that normally takes up to 5000 years. In 1995 an ancient lava flow with an unusual magnetic pattern was discovered in Oregon. It suggested that the field at the time was moving by 6 degrees a day - at least 10,000 times faster than usual. "Not many people believed it," says Scott Bogue of Occidental College in Los Angeles.

They Crawl, They Bite, They Baffle Scientists

THE ICK FACTOR The lab of Stephen A. Kells, a University of Minnesota entomologist. Bedbugs are not known to transmit disease. Allen Brisson-Smith for The New York Times

From The New York Times:

Don’t be too quick to dismiss the common bedbug as merely a pestiferous six-legged blood-sucker.

Think of it, rather, as Cimex lectularius, international arthropod of mystery.

In comparison to other insects that bite man, or even only walk across man’s food, nibble man’s crops or bite man’s farm animals, very little is known about the creature whose Latin name means — go figure — “bug of the bed.” Only a handful of entomologists specialize in it, and until recently it has been low on the government’s research agenda because it does not transmit disease. Most study grants come from the pesticide industry and ask only one question: What kills it?

A Triple-A pitcher shocked the baseball world with a pitch clocked at an insanely fast 105 mph. Here's why we won't see pitchers throw it much faster than this—ever.

Last Friday was a mixed bag for fans of the fastball. Early in the day, the Washington Nationals announced that phenom Stephen Strasburg, who hurled a 101-mph pitch in his debut in June, would likely require Tommy John surgery for his injured elbow; a procedure that could sideline him for up to 18 months. But later that night Aroldis Chapman, a 22-year-old Cuban defector pitching for the Cincinnati Reds' triple-A affiliate in Louisville, captured baseball fans' attention when he threw a pitch clocked at 105 mph.

One Reason Dieting Does Not Work

That’s The Way The Cookie Crumbles -- The Economist

One reason dieting does not work.

IF, BY chance, you are served an unusually large slice of pizza, compared with what others appear to be getting, would that experience incline you, some minutes later, to eat more cookies or fewer when platefuls came your way? That depends, it turns out, on whether you are on a diet. Those who are not eat fewer cookies, whereas those who are see the excessive pizza as a licence to pig out. It is a demonstration of what Janet Polivy, a psychologist at the University of Toronto, refers to as the “what the hell” effect—a phenomenon familiar from real life to which Dr Polivy has given scientific respectability, most recently in a paper published in the latest edition of Appetite.

Back in the eighties around 2,600 men were diagnosed with oesophageal cancer every year but now the figure is more than 5,100.

The most dramatic rise was among men in their 50s, as rates increased by 67 per cent over the same period.

When Drones Go Wild

When Drones Go Rogue In Friendly Skies, How Do We Bring Them Home? -- Popular Science

An advanced fly-by-wire system capable of landing grossly damaged unmanned aircraft—demonstrated on video saving a plane missing 80 percent of one wing—is key to solving one of unmanned flight’s biggest problems.

Word spread last week that a rogue MQ-8B Fire Scout copter drone entered restricted airspace just 40 miles shy of Washington D.C. after losing contact with its operators. The revelation occurred smack in the middle of AVUSI 2010, the world’s largest UAV tradeshow. And it served as a poignant reminder that all the game-changing technology on display here at the Denver Convention Center still has some innovating to do, especially when flight crews lose control of their unmanned craft.

My Comment: The video is impressive .... watch it.

Shape-Shifting Robot Compensates For Damaged Limb

From New Scientist:

Think that shape-shifting robots, or ones that march on no matter how many limbs they lose, are just for Terminator films? Think again. A team of European roboticists have developed software that allows a modular robot to adapt when one part stops working.

David Johan Christensen at the University of Southern Denmark in Odense, working with Alexander Spröwitz and Auke Ijspeert at the Swiss Federal Institute of Technology in Lausanne, simulated a quadruped robot constructed from a dozen Roombots – identical rounded robots that have been developed in Lausanne and which can combine to form a variety of modular shapes (see picture).

Astronaut’s Eye View: Time-Lapse Videos of Earth

From Wired Science:

A NASA astronaut on the Space Shuttle Endeavor brought space back down to Earth. Astronaut Don Pettit took over 85 time-lapsed videos of Earth from his stint on the International Space Station to highlight features of the changing planet.

"There is phenomenology that happens on a timescale that you can't see in real time," he said. "It occurred to me that making time-lapse movies on the space station would bring out things that you normally don't observe."

Death Of The Couch Potato:

More users are watching TV on their laptops than ever before, according to a new study (picture posed by model)

Death Of The Couch Potato: Study Finds More Than A Third Of Viewers Now Watch Their Favourite TV Shows Online -- Daily Mail

An increasing number of viewers are watching their favourite TV shows online rather than on television, a new survey as found.

More than a third of users (34 per cent) now watch their favourite programmes online compared to only 29 per cent who watch them mostly on television.

The figures - from a joint survey by SeeSaw.com and Radio Times - show how the way we consume television is changing rapidly.

My Comment: Count me as one of those who watches 90% of his shows and movies online.

Double Space Strike 'Caused Dinosaur Extinction'

From The BBC:

The dinosaurs were wiped out 65 million years ago by at least two space impacts, rather than a single strike, a new study suggests.

Previously, scientists had identified a huge impact crater in the Gulf of Mexico as the event that spelled doom for the dinosaurs.

Now evidence for a second impact in Ukraine has been uncovered.

This raises the possibility that the Earth may have been bombarded by a whole shower of space rocks.

My Comment: Regardless if there was one or more asteroid strikes .... it was a bad day for the dinosaurs when the first one happened.

Oxford English Dictionary 'Will Not Be Printed Again'

The second OED was published in 1989 Photo: GETTY

From The Telegraph:

The next edition of the Oxford English Dictionary, the world’s most definitive work on the language, will never be printed because of the impact of the internet on book sales.

Sales of the third edition of the vast tome have fallen due to the increasing popularity of online alternatives, according to its publisher.

A team of 80 lexicographers has been working on the third edition of the OED – known as OED3 – for the past 21 years.
