DNA Fingerprinting 25 Years Old

From BBC:

The scientist behind DNA fingerprinting has called for a change to the law governing DNA databases on the 25th anniversary of his discovery.

Professor Sir Alec Jeffreys uncovered the process by chance in his laboratory at Leicester University.

The technique has since been used to solve crimes and identity cases.

But it has also led to controversy over profiles kept on the national DNA database. "Innocent people do not belong on that database," he said.

E-book Readers Still Owned By Small Niche

From CNET:

The tech industry buzzes a lot about e-book readers. But how widely are they actually used?

Among 1,529 consumers who responded to a July 2009 questionnaire from research firm In-Stat, only 5.8 percent currently own an e-book reader. And only 11 percent of those questioned said they planned to buy one in the next 12 months, according to the In-Stat report released this week.

Those low results may be even more significant given that In-Stat's survey audience consisted of high-end consumers who typically adopt new technology earlier than the general public.

NASA & Its Discontents: Frustrated Engineers Battle With NASA Over The Future Of Spaceflight

From Popular Mechanics:

A group of renegade space vehicle designers, including NASA engineers bucking their bosses, are publicly crying out against the current Shuttle retirement plan. Their proposed plan, called Jupiter Direct, is an affront to NASA's current plans for the Ares I rocket, which they say is more costly and time-consuming than it needs to be. This is their story.

New Glass Resists Small Explosions

From Live Science:

Scientists have created a new type of blast-resistant glass that is thinner, lighter and less vulnerable to small-scale explosions than existing glass.

In tests, the improved glass design has been shown to withstand a hand grenade-strength bomb explosion originating close to the window panel. The blast caused the glass panel to crack, but didn’t puncture the composite layer.

Brain Cells Slicker Than We Thought

From New Scientist:

Rat brain cells waste little energy when talking to one another. That finding might not sound unusual, but it challenges the long-standing view that brain cells are extremely inefficient at sending signals.

In 1939, Alan Hodgkin of the University of Cambridge and Andrew Huxley of University College London experimented on nerve cells from the giant squid. They concluded that the energy of electrical signals sent along axons – the cells' "cables", each 1 millimetre in diameter in the giant squid – was four times the theoretical minimum.

From The New York Times:

Throughout his life, Charles Darwin surrounded himself with flowers. When he was 10, he wrote down each time a peony bloomed in his father’s garden. When he bought a house to raise his own family, he turned the grounds into a botanical field station where he experimented on flowers until his death. But despite his intimate familiarity with flowers, Darwin once wrote that their evolution was “an abominable mystery.”

Wolves Aren’t Making It Easy for Idaho Hunters

From The New York Times:

BOISE NATIONAL FOREST, Idaho — Hunting and killing are not the same thing. Even as Idaho has sold more than 14,000 wolf-hunting permits, the first 10 days of the first legal wolf hunt here in decades have yielded only three reported legal kills.

Such modest early results might seem surprising in a state that has tried for years to persuade the federal government to let it reduce the wolf population through hunting.

Idahoans, among the nation’s most passionate hunters, are learning that the wolf’s small numbers — about 850 were counted in the state at the end of last year — make it at once more vulnerable and more elusive.

Frankfurt Motor Show: Mercedes SLS AMG Is The New 'Gullwing'

From The Telegraph:

A dashing new interpretation of Mercedes-Benz's fabled "Gullwing" model, called the SLS AMG, will be one of the stars of the Frankfurt Motor Show.

Gone are the familiar rounded nose, circular headlights and triangular rear quarter-lights of the 1950s model.

In their place, the German firm will unveil a chiselled, aerodynamic new model with vertically slanted headlights, a steeply-raked windscreen and taut, muscular, ground-hugging lines.

You Can Believe Your Eyes: New Insights Into Memory Without Conscious Awareness

New findings may shed light on the role of the hippocampus in memory and awareness, as they suggest that even when people fail to recollect a past event, the hippocampus might still support an expression of memory through eye movements. (Credit: iStockphoto)

From Science Daily:

ScienceDaily (Sep. 10, 2009) — Scientists may have discovered a way to glean information about stored memories by tracking patterns of eye movements, even when an individual is unable (or perhaps even unwilling) to report what they remember. The research, published by Cell Press in the September 10th issue of the journal Neuron, provides compelling insight into the relationship between activity in the hippocampus, eye movements, and both conscious and unconscious memory.

From Technology News:

On Tuesday, after months of deliberation, the independent committee charged with reviewing the future of the U.S. human space program released a summary report of its findings, a document that will guide key decisions that lie ahead for the Obama administration.

According to the report, the current crisis facing NASA lies with its budget, and not with technical or programmatic issues. "The report clearly stated that the current program is not executable or sustainable with the budget that we have," says Scott Pace, director of the Space Policy Institute at George Washington University, in DC.

Our Stone Age Ancestors Wore Bright And Garish Clothes

Our stone age ancestors may have worn brightly coloured threads rather than drab skins as portrayed in films like One Million Years BC

From The Daily Mail:

They are normally pictured wearing drab furs and skins. But an astonishing new discovery suggests that our Stone Age ancestors had a taste for garish, colourful clothes.

Archaeologists have uncovered an extraordinary haul of pink, turquoise and black fibres that were used to make thread more than 34,000 years ago.

The flax fibres, which were buried in a cave in the hills of the Republic of Georgia, were discovered by an international team of fossil hunters.

The iPod Is Dead

From Slate:

One sign that Steve Jobs is back to his old self: He's already sniping at rivals. After Apple's iPod launch event on Wednesday, the New York Times' David Pogue asked the CEO whether he has doubts—as he's expressed in the past—about the market for e-readers, especially Amazon's Kindle. Jobs said he was still skeptical. Amazon, he pointed out, has never released sales numbers for the Kindle, and "usually, if they sell a lot of something, you want to tell everybody." More importantly, Jobs doesn't think people want to buy a device just to read books. "I'm sure there will always be dedicated devices, and they may have a few advantages in doing just one thing," Jobs said. "But I think the general-purpose devices will win the day."
