Sunshine-to-Petrol Project Seeks Fuel From Thin Air
15.12.2007 | Press monitoring
Using concentrated **solar energy** to reverse combustion, a research team from Sandia National Laboratories is building a prototype device intended to chemically “reenergize” carbon dioxide into carbon monoxide using concentrated solar power. The carbon monoxide could then be used to make hydrogen or serve as a building block to synthesize a...
Scientists set to release new disease-resistant wheat
14.12.2007 | Press monitoring
'Mace', a new winter wheat cultivar developed by Agricultural Research Service scientists and cooperators, could give growers an added measure of insurance against outbreaks of wheat streak mosaic virus.
Neurotransmitters in biopolymers stimulate nerve regeneration
13.12.2007 | Press monitoring
The technique would use a biodegradable polymer containing a chemical group that mimics the neurotransmitter acetylcholine to spur the growth of neurites, which are projections that form the connections among neurons and between neurons and other cells. The biomimetic polymers would then guide the growth of the regenerating nerve....
Methane from microbes: a fuel for the future
12.12.2007 | Press monitoring
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today.
Elasticity Of Short DNA Molecules: In Theory And Experiment
11.12.2007 | Press monitoring
DNA, the biomolecule that provides the blueprint for life, has a lesser-known identity as a stretchy polymer. The authors have found a flaw in the most common model for DNA elasticity, a discovery that will improve the accuracy of single-molecule research and perhaps pave the way for DNA to become an official standard for measuring picoscale...
Nanotube-producing Bacteria Show Manufacturing Promise
10.12.2007 | Press monitoring
Two engineers at the University of California, Riverside are part of a binational team that has found semiconducting nanotubes produced by living bacteria – a discovery that could help in the creation of a new generation of nanoelectronic devices.
Researcher develops realistic cancer growth models
9.12.2007 | Press monitoring
Scientists can only develop new cancer drugs or search for cures by testing their theories on the real thing. Traditionally, they've done so by culturing cancer cells on petri dishes or plastic slides. But those cancer cells do not behave the way they do in the body. They only partially re-create the aggressive behavior of tumors in real...
Golden bullet shows promise for killing common parasite
8.12.2007 | Press monitoring
Researchers in Australia report development of a new type of gold nanoparticle that destroys the parasite responsible for toxoplasmosis, a potentially serious disease acquired by handling the feces of infected cats or eating undercooked meat. Their so-called "golden bullet" could provide a safer, more effective alternative for treating the disease...
Implanting embryonic cardiac cells prevents arrhythmias
7.12.2007 | Press monitoring
When researchers at Cornell, the University of Bonn and the University of Pittsburgh **transplanted living embryonic heart cells** into cardiac tissue of mice that had suffered heart attacks, the mice became resistant to cardiac arrhythmias, thereby avoiding one of the most dangerous and fatal consequences of heart attacks.
Edible Coatings Of Whey Help Keep Pathogens Off Meats
6.12.2007 | Press monitoring
Ready-to-eat meats are popular with consumers. But after the initial food processing, they are also vulnerable to recontamination by pathogenic bacteria. A solution turns out to be an application of an antimicrobial-incorporated edible film coating that will fend off the pathogens.
