DNA May Help Build Next Generation of Chips

From Gadget Lab:

In the race to keep Moore’s Law alive, researchers are turning to an unlikely ally: DNA molecules that can be positioned on wafers to create smaller, faster and more energy-efficient chips.

Researchers at IBM have made a significant breakthrough in their quest to combine DNA strands with conventional lithographic techniques to create tiny circuit boards. The breakthrough, which allows for the DNA structures to be positioned precisely on substrates, could help shrink computer chips to about a 6-nanometer scale. Intel’s latest chips, by comparison, are on a 32-nanometer scale.

Isotope Crisis Threatens Medical Care

Domestic source-to-be?At 10 megawatts, the University of Missouri Research Reactor is the largest university research reactor in the country. Within two months, officials there will submit a proposal to the Energy Department to build a facility that would ultimately allow domestic production of a medical isotope that's currently in critically short supply.University of Missouri Research Reactor

From Science News:

Global production of the feedstock for the leading medical-imaging isotope is low and erratic, putting health care in jeopardy.

Within the next two weeks, the vast majority of radioactive-imaging medical tests could be delayed or replaced by less desirable procedures. The reason: temporary shutdowns of Canadian and Dutch reactors that together normally provide some 70 percent of the world’s supplies of the isotope molybdenum-99 and at least 80 percent of North American supplies.

Early Farming Methods Caused Climate Change, Say Researchers

From The Guardian:

Farmers thousands of years ago cleared land by burning forests and moved to a new area once the yields declined, say scientists.

Farmers who used "slash and burn" methods of clearing forests to grow crops thousands of years ago could have increased carbon dioxide levels enough to change the climate, researchers claimed today.

The US scientists believe that small populations released carbon emissions as they cleared large tracts of land to produce relatively meagre amounts of food.

They were much less efficient than farmers using today's agricultural practices because there were no constraints on land.

In Galileo’s Footsteps

Galileo

From Newsweek:

For the first time in hundreds of years, the most powerful telescopes may soon come from Europe.
Galileo has been getting a lot of press lately, and no wonder. Four centuries ago this year, the Italian genius pointed his small, primitive telescope at the night sky and saw wonders nobody had imagined. His discoveries transformed our view of the heavens, but also infected astronomers with a permanent desire to peer just a bit deeper in the universe and find a few more cosmic secrets. Which is why, less than 20 years after they put the finishing touches on a generation of telescopes so big they would have made the Renaissance stargazer swoon, the astronomers are at it again. Three teams are racing to build telescopes four times wider and with up to 16 times the light gathering power than what exists now, and to have them trained on the stars by 2018.

Augmented Reality Reveals History to Tourists

From : Science News Service

Doing virtual reality one better, a consortium of technology companies and European Union countries have created a "visual time machine" that allows tourists equipped with a smart phone to take a picture of an ancient object and then instantly review its history and see what it originally looked like.

This new technology, dubbed the "Intelligent Tourism and Cultural Information through Ubiquitous Services" (iTacitus, after the Roman historian), brings augmented reality to museums, palaces, castles and other tourist attractions, according to its developers."[Tourists] can look at a historic site and, by taking a photo or viewing it through the camera on the mobile device, be able to access much more information about it," said Luke Speller, a scientist with the BMT engineering group based in the U.K. "They are even able to visualize, in real time, how it looked at different stages in history."

Defense Last In WH Science Goals

From DoD Buzz:

The Obama administration’s budget guidance for 2011 makes clear that basic research spending will stay flat in most areas or decline, including at the Pentagon.

Money will first go to research that can “drive economic recovery, job creation, and economic growth,” says the guidance issued in an Aug. 4 memo by White House Office of Management and Budget Director Peter Orszag. The administration also makes clear that since they expect little new money for science and technology funding then government agencies must move dollars to what it calls four “practical challenges.”

From CNET:

The X-51A WaveRider is one step closer to its inaugural test flight later this year, now that airmen at Edwards Air Force Base have successfully "mated" the scramjet-propelled vehicle to a B-52 Stratofortress.

In December, an Air Force Flight Test Center B-52 is scheduled to papoose the X-51A to 50,000 feet over the Pacific Ocean before cutting it loose. At that point, a solid rocket booster from an ATACMS missile will fire up, accelerating the X-51 to about Mach 4.5. That's when the supersonic combustion ramjet kicks in, pushing the WaveRider to more than Mach 6 for up to five minutes, longer than all of its predecessors combined. NASA tests have reached Mach 9.6, or nearly 7,000 mph, according to some reports, but not for very long. The previous record was less than 10 seconds. Flight data will be telemetered back to Edwards Force Base before the X-51A test vehicle crashes into the Pacific.

Fire Used to Make Better Tools 75,000 Years Ago

From :Live Science

Early humans crossed a threshold around 75,000 years ago, when they started painting symbols, carving patterns and making jewelry. A new study found they also began to use fire to make tools around that time.

Until now, this complex, multi-step process for tool making was only known to occur as recently as 25,000 years ago in Europe. But the new findings show this breakthrough occurred much earlier, and in Africa, not Europe.
By heating up stones in a fire before chipping away at them to make blades, early humans could make tools sharper and produce them more efficiently.
Scientists think this advancement represents a link between the earlier use of fire for cooking and warmth, and the later production of ceramics and metals

Early humans crossed a threshold around 75,000 years ago, when they started painting symbols, carving patterns and making jewelry. A new study found they also began to use fire to make tools around that time.

Until now, this complex, multi-step process for tool making was only known to occur as recently as 25,000 years ago in Europe. But the new findings show this breakthrough occurred much earlier, and in Africa, not Europe.

By heating up stones in a fire before chipping away at them to make blades, early humans could make tools sharper and produce them more efficiently.

Another Nutritional Challenge For Space Food

From L.A. Times:

You may have read yesterday’s story about the food scientists at NASA who have their hands full trying to figure out what astronauts will eat when they blast off on a three-year mission to Mars sometime after the year 2030. For a variety of reasons, the food served on the space shuttle and International Space Station won’t cut it – it’s too heavy, too bulky, and its chemistry makes it prone to spoilage after only a couple of years.

And now the NASA scientists have identified another problem: many of the essential vitamins, amino acids and fatty acids in the foods will degrade over the course of such a long mission.

Pictured: Stunning New Image Of Mars Show Half-Mile Wide Crater Complete With Sand Dunes

This image of the Victoria Crater in the Meridiani Planum region of Mars was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter

From The Daily Mail:

It is one of the most dramatic images to ever emerge from Mars.

In fact, this extraordinary photograph is so clear that even the sand dunes at the base of the half-mile wide canyon are visible.

Experts even believe that they can see the tracks of a Mars lander on the left-hand corner of the Victoria Crater.

From The Guardian:

Ice and glacier coverage at lower altitudes in cold climates more important than collision of tectonic plates, researchers find.

Scientists have solved the mystery of why the world's highest mountains sit near the equator - colder climates are better at eroding peaks than had previously been realised.

Mountains are built by the collisions between continental plates that force land upwards. The fastest mountain growth is around 10mm a year in places such as New Zealand and parts of the Himalayas, but more commonly peaks grow at around 2-3mm per year.
