Fungus Threatens Prehistoric Cave Drawings

From CBS News:

Scientists Meet To Try And Save Lascaux’s Murals In France At Risk Due To Global Warming.

(AP) Geologists, biologists and other scientists convened Thursday in Paris to discuss how to stop the spread of fungus stains – aggravated by global warming – that threaten France’s prehistoric Lascaux cave drawings.

Black stains have spread across the cave’s prehistoric murals of bulls, felines and other images, and scientists have been hard-pressed to halt the fungal creep.

Marc Gaulthier, who heads the Lascaux Caves International Scientific Committee, said the challenges facing the group are vast and global warming now poses an added problem.


Genetic Discovery Could Lead To Advances In Dental Treatment

From Science Daily:

ScienceDaily (Feb. 24, 2009) — Researchers have identified the gene that ultimately controls the production of tooth enamel, a significant advance that could some day lead to the repair of damaged enamel, a new concept in cavity prevention, and restoration or even the production of replacement teeth.

The gene, called Ctip2, is a “transcription factor” that was already known to have several functions – in immune response, and the development of skin and the nervous system. Scientists can now add tooth development to that list.

The findings were just published in the Proceedings of the National Academy of Sciences.


Why Women Cannot Read Maps

Are we lost? Women tend to describe directions as ‘right of’ and ‘left of’ landmarks, while men are better at reading maps, a study found

Are We Lost? Why Women Are Worse At Reading Maps But Can Find Those Misplaced Keys — Daily Mail

Women are worse at reading maps but better at finding lost items, research into how the sexes perceive beauty has revealed.

U.S Scientists asked 10 men and 10 women to view a series of unfamiliar pictures. The participants were told to give their impressions of the images and whether or not they found them beautiful.

The scientists also used a technique called magnetoencephalography (MEG) to measure changes in the magnetic fields generated by active neurons in the brain.


Is The Internet Warping Our Brains?

From Live Science:

The Internet is no doubt changing modern society. It has profoundly altered how we gather information, consume news, carry out war, and create and foster social bonds. But is it altering our brains? A growing number of scientists think so, and studies are providing data to show it.

What remains to be seen is whether the changes are good or bad, and whether the brain is, as one neuroscientist believes, undergoing unprecedented evolution.

Scientists Expect To Create Life In Next 10 years

First cell of synthetic life can only be seen under a microscope.

WASHINGTON – Around the world, a handful of scientists are trying to create life from scratch and they’re getting closer.

Experts expect an announcement within three to 10 years from someone in the now little-known field of “wet artificial life.”

“It’s going to be a big deal and everybody’s going to know about it,” said Mark Bedau, chief operating officer of ProtoLife of Venice, Italy, one of those in the race. “We’re talking about a technology that could change our world in pretty fundamental ways — in fact, in ways that are impossible to predict.”


250 DVDs In A Quarter-Sized Device — Coming Soon?

“I expect that the new method we developed will transform the microelectronic and storage industries, and open up vistas for entirely new applications,” said co-lead investigator Thomas Russell.

From NBC Bay Area News:

A new technique developed by scientists at UC Berkeley and University of Massachusetts Amherst may drastically increase the ability of devices to store things.

Cal officials called the technique “innovative and easily implemented,” on Thursday.

The method lets microscopic nanoscale elements precisely assemble themselves over large surfaces.

Scientists said the technique could soon open doors to dramatic improvements in the data storage capacity of electronic media.


The Race for Bosons

Fermilab’s Tevatron: Reidar Hahn/Fermilab

From Pop Science:

Competitor takes advantage of LHC’s accident.

Particle accelerator smackdown! Scientists working on Fermilab’s Tevatron have been talking some smack (in the politest of terms), saying they have a good shot at finding the elusive Higgs boson before the currently out-of-commission Large Hadron Collider does.

Also in today’s links: a map of emissions, why not to keep chimps as pets (besides the now-obvious), and more.


Scientists Close In On 'Universal' Vaccine For Flu: Study

From Breitbart/AFP:

Scientists on Sunday unveiled lab-made human antibodies that can disable several types of influenza, including highly-lethal H5N1 bird flu and the “Spanish Flu” strain that killed tens of millions in 1918.

Tested in mice, the antibodies work by binding to a previously obscure structure in the flu virus which, when blocked, sabotages the pathogen’s ability to enter the cell it is trying to infect, according to the study.

Because this structure — described by one scientist as a “viral Achilles’ heel” — is genetically stable and has resisted mutation over time, the antibodies are effective against many different strains.


Laptop's Days Are Over!

 Amazing technology from Japan 

. . . . 
but can you guess what it is ? 

Look closely and guess what they could be…  


Are they pens with cameras? 

 Any wild guesses? No clue yet? 

Ladies and gentlemen… congratulations! 
You’ve just looked into the future… yep that’s right! 

You’ve just seen something that will replace your PC in the near future. 

Here is how it works: 

In the revolution of miniature computers, scientists have made great developments with bluetooth technology.. . 

This is the forthcoming computers you can carry within your pockets 

This ‘pen sort of instrument’ produces both the monitor as well as the keyboard on any flat surfaces from where you can carry out functions you would normally do on your desktop computer. 

Can any one say, ‘Good-bye laptops?’

Scientists Make Advances On 'Nano' Electronics

From Wired Science/Reuters:

CHICAGO (Reuters) – Two U.S. teams have developed new materials that may pave the way for ever smaller, faster and more powerful electronics as current semiconductor technology begins to reach the limits of miniaturization.

One team has made tiny transistors — the building block of computer processors — a fraction of the size of those used on advanced silicon chips.

Another has made a film material capable of storing data from 250 DVDs onto a surface the size of a coin.
