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.

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.

Can Battlefield Robots Take The Place Of Soldiers?

Can battlefield land-robots be made to obey the rules of war?

From The BBC:

Can war be fought by lots of well-behaved machines, making it "safer for humans"? That is the seductive vision, and hope, of those manufacturing and researching the future of military robotics.

With 8,000 robots already in use, they believe they can bring about a military revolution.

Most of the robots currently deployed on land deal with non-combat tasks such as bomb disposal - unlike lethal aerial drones.

But Bob Quinn, who works for the US subsidiary of the British robot manufacturer QinetiQ, says the future promises more armed robots on the battlefield, including driverless vehicles.

Why NASA Picked Stormy Florida

From Christian Science Monitor:

Weather thwarts shuttle launches. But important factors favor this state.

If the space shuttle Endeavour lifts off in the early hours of Feb. 7, it will be the first shuttle launch in more than half a year to leave on time.

Each of the last three missions has been delayed for days or weeks – with one held back by a scheduling conflict and two by stormy weather. Despite its "Sunshine State" moniker, Florida has postponed shuttles due to five hurricanes, two hailstorms, a tropical storm, lightning damage, countless cloudy days, and meddlesome woodpeckers stabbing a fuel tank. And if the temperature goes below 36 degrees F., as it did earlier this month, Cape Canaveral's fickle weather will thwart yet another scheduled blastoff.

EVERETT, Washington — Boeing spent more than five years and hundreds of millions of dollars developing its new 747-8, but in the end the decision on whether to send the company’s biggest aircraft ever down the runway and into the air for the first time rested with the man in the cockpit.

The flight window for the 747-8’s maiden flight opened at 10 a.m. Monday, but Mother Nature had other plans. Paine Field was socked in by low clouds, and the clock was ticking. Mark Feuerstein, Boeing’s chief test pilot for the 747 program — the man who has spent years preparing for the day — had to decide whether to proceed.

The Dawn Of Civilization: Writing, Urban Life, And Warfare -- Discovery Magazine

An extraordinary ancient Syrian settlement shines a light on one of the most important moments in human history.

Joan Oates’s sharp blue eyes spotted something that was not right. Standing on the windy summit of a vast, human-made mound in northeastern Syria, the wiry 81-year-old archaeologist noticed an ugly scar that had been left by a backhoe on one of the smaller mounds ringing the ancient city of Nagar, where she has excavated for a quarter century. Oates had just arrived to begin her latest season at the site, and this blemish on her cherished landscape annoyed her. Two young men on her team volunteered to investigate the damage. They returned, shaken. Jumping into the trench, one of them had come face-to-face with a skull. “Everywhere we looked, there were human bones,” one recalls. “There were an enormous number of dead people.”

From Technology Review:

Autoantibodies could alert doctors to cancer development.

A new screening tool developed by scientists in Denmark may help detect the earliest stages of cancer by taking advantage of the body's own defenses. The researchers constructed a microarray system that analyzes patients' blood for a specific class of immune agents called autoantibodies. These are agents that attack the body's own tissue, targeting what they perceive as "foreign" cells, such as specific molecules on the surface of tumors.
