The moment one of the World Trade Centre towers begins to crumble in New York

From The Daily Mail:

We have seen the Twin Towers collapse hundreds of times on TV. The steel and glass skyscrapers exploding like a bag of flour, the dust and smoke pluming out across Manhattan. But never like this, from above.

Nine years after the defining moment of the 21st century, a stunning set of photographs taken by New York Police helicopters forces us to look afresh at a catastrophe we assumed we knew so well.

You know but cannot see the 2,752 men, women and children who died at the World Trade Centre on September 11, 2001. None is visible here.

From Science Daily:

Science Daily (Feb. 10, 2010) — Researchers have measured the degradation of the planet's soil using the Life Cycle Assessment (LCA), a scientific methodology that analyses the environmental impact of human activities, and which now for the first time includes indicators on desertification. The results show that 38 percent of the world is made up of arid regions at risk of desertification.

Why Advertised Broadband Speeds Lag Behind Reality

From Live Science:

Downloading music from the Internet, streaming video or even browsing most websites nowadays requires fast broadband Internet connections such as a digital subscriber line (DSL) or cable. But slower-than-advertised connection speeds caused by growing network congestion and artificial restrictions by some Internet Service Providers (ISPs) have left broadband consumers frustrated at times, and for good reason.

Genes Reveal 'Biological Ageing'

From The BBC:

Gene variants that might show how fast people's bodies are actually ageing have been pinpointed by scientists.

Researchers from the University of Leicester and Kings College London say the finding could help spot people at higher risk of age-related illnesses.

People carrying the variant had differences in the "biological clock" within all their cells.

The British Heart Foundation said the findings could offer a clue to ways of preventing heart disease.

Valium 'Works Like Heroin'

From The Telegraph:

Valium, the tranquilliser once known as "mother's little helper", works by boosting the same brain chemical as heroin and cannabis, a study shows.

Diazepam, better known by the defunct brand name Valium, increases "feel good" dopamine levels which are typically targeted by other addictive drugs.

The finding, published in Nature, helps explain why people get hooked on the drug - nick-named "blues" or "vallies" - and may aid the design of safer alternatives.

Scientists Seek Better Way To Do Climate Report

REFORM CLIMATE: Is there any need for the Intergovernmental Panel on Climate Change to continue its work of assessing the global environmental threat? NASA

From ABC News:

Scientists call for better way to do climate report; errors tarnish Nobel Prize-winning effort.

A steady drip of unsettling errors is exposing what scientists are calling "the weaker link" in the Nobel Peace Prize-winning series of international reports on global warming.

The flaws — and the erosion they've caused in public confidence — have some scientists calling for drastic changes in how future United Nations climate reports are done. A push for reform being published in Thursday's issue of a prestigious scientific journal comes on top of a growing clamor for the resignation of the chairman of the Intergovernmental Panel on Climate Change.

From Live Science:

A few tufts of hair frozen in the permafrost of Greenland for more than 4,000 years have allowed scientists to sequence the genome of an ancient human for the first time.

The hairs belonged to a member of the ancient Saqqaq culture of Greenland, the first humans known to inhabit the icy island. Scientists have long wondered where the Saqqaq came from and whether or not they were the ancestors of today's modern Inuit and Greenlanders. The new findings, detailed in the Feb. 11 issue of the journal Nature, have helped to settle that question.

Obesity In Kids: Three Lifestyle Changes That Help

From Time Magazine:

To curb the childhood-obesity epidemic, health experts have long urged parents to make healthy changes to their family's lifestyle — such as eating nutritiously, reducing TV time, exercising and getting a good night's sleep.

Individually, these behaviors have been linked to a lower risk of obesity in kids, but researchers at Ohio State University were interested in learning whether their effect might be cumulative — that is, whether families who adopted not just one but two or more of these behaviors could reduce their children's risk of obesity even further.

Google Takes On Facebook, Twitter With ‘Buzz’

From Epicenter:

MOUNTAIN VIEW, California — Google says there’s already plenty of social networking information out there, and what the world really needs is a way to wrangle Twitter, MySpace and Facebook to tame information overload. If its “solution” guts the existing players, so much the better for the search giant.

Google has largely failed in its attempts to build a social networking site before, so it’s taking a different tack: With the Tuesday launch of Google Buzz, the company is pushing a new way to organize by building on a “destination” that millions of people already visit constantly, every day: Gmail.

Botox May Deaden Not Just Nerves, But Emotions, Too

From Discover Magazine:

Sure, Botox can banish crows feet, smooth those wrinkles, and lift those frown lines, making the client look more youthful–and somewhat expressionless. But the treatment may have effects that are more than skin deep. A new study suggests that by paralyzing the frown muscles that ordinarily are engaged when we feel angry, Botox short-circuits the emotion itself [Newsweek].

From Technology Review:

Government incentives and lower solar prices are starting to pay off.

In a few years, the United States is likely to be the world's largest market for solar power, eclipsing Germany, which has taken the lead as a result of strong government incentives in spite of the relative paucity of sunlight in that country. A number of factors could make growth possible in the United States--especially changes in legislation that give utilities incentives to create large solar farms.

New Armored Wall System Assembles Like Legos, Could Replace Sandbags In Afghanistan

McCurdy's Armor Dynamic Defense Materials

From Popular Science:

Attention recruits. Those of you landing in Afghanistan in coming months may not have to engage in the sandbag stacking and trench digging usually associated with lowly grunt-dom. An $800,000 investment in an armored wall system known as McCurdy’s Armor could have Marines rapidly erecting 6.5-foot-tall mortar-, RPG- and bullet proof fortresses in less than an hour, saving the days it can take to fortify an area by conventional means and making forward-operating units more nimble.

From Science Daily:

Science Daily (Feb. 9, 2010) — Two patients with rare lesions to the brain have provided direct of evidence of how we make decisions -- and what makes us dislike the thought of losing money.

Researchers at the California Institute of Technology studied a phenomenon known as 'loss aversion' in two patients with lesions to the amygdala, a region deep within the brain involved in emotions and decision-making. The results of the study, part-funded by the Wellcome Trust, are published February 8 in the journal Proceedings of the National Academy of Sciences.
