A Hot Piece of Hardware: NASA’s New Orbiter Will Map the Entire Sky in Infrared


From Discover Magazine:

Stars and other astronomical phenomena radiate across the electromagnetic spectrum, on both sides of the puny band of visible light that the human eye can pick up. NASA’s newest toy, set for a Friday launch into space, will map the infrared portion of that radiation—and do it across the entire sky.

Five Ways To Revolutionise Computer Memory

Digital memory is getting smaller and smaller (Image: Chung Sung-Jun/Getty)

From New Scientist:

Once upon a time, not so long ago, the idea that you might store your entire music collection on a single hand-held device would have been greeted with disbelief. Ditto backing up all your essential computer files using a memory stick key ring, or storing thousands of high-resolution holiday snaps in one pocket-sized camera.

What a difference a decade makes. The impossible has become possible thanks to the lightning rise of a memory technology with the snazzy name of "flash".

Sobering News: Coffee Increases Drunkenness

From The Telegraph:

Drinking coffee does not sober you up – and may actually further impair your judgement, new research suggests.

The combination of alcohol and caffeine produces a potentially lethal mix that just makes it harder to realise you are actually drunk in the first place.

And the study published in Behavioural Neuroscience suggests popular caffeinated energy drinks could also raise risks from intoxication rather than lessen them.

To Save Soldiers on The Battlefield, Darpa Invests In Suspended Animation

Better Medevac Darpa is investing nearly $10 million in creating a medical cocktail that will suspend soldiers' animation after sustaining wounds in battle, reducing their need for oxygenated blood and keeping them (barely) alive until they can receive proper treatment.

From Popular Science:

An active battlefield is a really inconvenient place to lose a lot of blood. But naturally that's exactly where soldiers sustain the bulk of their life-threatening injuries, so Darpa is committing $9.9 million to finding drugs that can extend the "golden hour" -- the one-hour window that medics generally have to bring a soldier back from severe blood loss -- by as much as six hours.

Untold Levels Of Oil Sands Pollution On Athabasca River Confirmed

From Science Daily:

ScienceDaily (Dec. 8, 2009) — After an exhaustive study of air and water pollution along the Athabasca River and its tributaries from Fort McMurray to Lake Athabasca, researchers say pollution levels have increased as a direct result of nearby oil sands operations.

University of Alberta biological sciences professor David Schindler was part of the team that conducted a long term air and water study and found high levels of Polycyclic Aromatic Compounds. PACs are a group of organic contaminants containing several known carcinogens, mutagens, and teratogens. The highest levels of PAC's were found within 50 kilometres of two major oil sands up graders.

Humans Have Hidden Sensory System

From Live Science:

The human body may be equipped with a separate sensory system aside from the nerves that gives us the ability to touch and feel, according to a new study.

Most of us have millions of different types of nerve endings just beneath the skin that let us feel our surroundings. However, the once-hidden and recently discovered skin sense, found in two patients, is located throughout the blood vessels and sweat glands, and most of us don't even notice it's there.

The Secrets Of Tutankhamun's Decaying Tomb

Scientists examining the flaking King Tut murals.

From The Independent:

Scientists mount inquiry into how millions of visitors to Egyptian boy king's chamber are destroying the wonder they came to see, reports Guy Adams.


Given the peace and quiet Tutankhamun enjoyed for three millennia, it has been a rough 87 years for him since he was discovered by Howard Carter in 1922. He was immediately relieved of his treasures; his tomb became one of the world's best-known tourist attractions, and finally, in 2005, his mummified corpse was hoiked out of its final resting-place to be studied by scientists.

MIT Plans To Rebuild Artificial Intelligence From The Ground Up

Artificial Intelligence: It's not what we think.

From Popular Science:

After 50 years and countless dead ends, incremental progress, and modest breakthroughs, artificial intelligence researchers are asking for a do-over. The $5 million Mind Machine Project (MMP), a patchwork team of two dozen academics, students and researchers, intends to go back to the discipline's beginnings, rebuilding the field from the ground up. With 20/20 hindsight, a few generations worth of experience, and better, faster technology, this time researchers in AI -- an ambiguous field to begin with -- plan to get things right.

From Live Science:


Petunias and potatoes may actually be carnivorous plants, scientists now suggest.

Indeed, carnivorous behavior may be far more widespread in plants than commonly thought — if we take a closer look, botanists said.

At least six different kinds of killer plants have been recognized since the time of Darwin, such as Venus flytraps, which snares insects between its jaw-like leaves, and pitcher plants, which capture victims in slippery pits. These plants apparently target animals to supplement their growth in harsh, nutrient-poor habitats.
