Data storage of tomorrow: Ferroelectricity on the nanoscale Posted: 10 Jul 2012 02:21 PM PDT Scientists have brought some clarity to the here-to-fore confusing physics of ferroelectric nanomaterials, pointing the way to multi-terabyte-per-square-inch of non-volatile computer memory chips.

Cyberwarfare, conservation and disease prevention could benefit from new network model Posted: 10 Jul 2012 02:17 PM PDT A new computer model could help military strategists devise the most damaging cyber attacks as well as guard America's critical infrastructure. The model also could benefit other projects involving interconnected groups, such as restoring ecosystems, halting disease epidemics and stopping smugglers.

Hubble unmasks ghost galaxies Posted: 10 Jul 2012 10:31 AM PDT Astronomers are studying some of the smallest and faintest galaxies in our cosmic neighborhood. These galaxies are fossils of the early Universe: They have barely changed for 13 billion years. The discovery could help explain the so-called "missing satellite" problem, where only a handful of satellite galaxies have been found around the Milky Way, against the thousands that are predicted by theories.

Waste to watts: Improving microbial fuel cells Posted: 10 Jul 2012 10:31 AM PDT Some of the planet's tiniest inhabitants may help address two of society's biggest environmental challenges: How to deal with the vast quantities of organic waste produced and where to find clean, renewable energy. Anode respiring bacteria generate useful energy in a device known as a microbial fuel cell.

Toward achieving one million times increase in computing efficiency Posted: 10 Jul 2012 10:30 AM PDT Researchers have created an entirely new family of logic circuits based on magnetic semiconductor devices. The advance could lead to logic circuits up to one million times more power-efficient than today's.

New biofuel process dramatically improves energy recovery, and uses agricultural waste Posted: 10 Jul 2012 10:30 AM PDT A new biofuel production process produces energy more than 20 times higher than existing methods. The results showcase a novel way to use microbes to produce biofuel and hydrogen, all while consuming agricultural wastes.

Searching genomic data faster: Biologists' capacity for generating genomic data is increasing more rapidly than computing power Posted: 10 Jul 2012 10:29 AM PDT In 2001, the Human Genome Project and Celera Genomics announced that after 10 years of work at a cost of some $400 million, they had completed a draft sequence of the human genome. Today, sequencing a human genome is something that a single researcher can do in a couple of weeks for less than $10,000. Since 2002, the rate at which genomes can be sequenced has been doubling every four months or so, whereas computing power doubles only every 18 months. Now a new algorithm drastically reduces the time it takes to find a particular gene sequence in a database of genomes.

Preclinical studies use specialized ultrasound to detect presence of cancer Posted: 10 Jul 2012 09:02 AM PDT Vessel "bendiness" can indicate the presence and progression of cancer. This principle led scientists to a new method of using a high-resolution ultrasound to identify early tumors in preclinical studies. The method, based on vessel bendiness or "tortuosity," potentially offers an inexpensive, non-invasive and fast method to detect cancer that could someday help doctors identify cancers when tumors are less than a centimeter in size.

Metamolecules that switch handedness at light-speed: Optically switchable chiral terahertz metamolecules developed Posted: 10 Jul 2012 09:02 AM PDT Scientists have created the first artificial molecules whose chirality can be rapidly switched from a right-handed to a left-handed orientation with a beam of light. This holds potentially huge possibilities for the application of terahertz technologies across a wide range of fields, including biomedical research, homeland security and ultrahigh-speed communications.

White LEDs lighting directly on paper Posted: 10 Jul 2012 06:34 AM PDT Imagine a white luminous curtain waving in the breeze. Or wallpaper that lights up your room with perfect white light.  The applications are not very far away. White LEDs, made from zinc oxide and a conducting polymer, can be manufactured directly on paper.
