Hot-spring bacteria reveal ability to use far-red light for photosynthesis
Bacteria growing in near darkness use a previously unknown process for harvesting energy and producing oxygen from sunlight, a research team led by a Penn State University scientist has discovered. The discovery ...
New manufacturing methods needed for 'soft' machines, robots
Researchers have developed a technique that might be used to produce "soft machines" made of elastic materials and liquid metals for potential applications in robotics, medical devices and consumer electronics.
New goggle-like device may lead to 3-D augmented reality technology that minimizes visual fatigue
Augmented reality is increasingly becoming… well … a reality. Smartphone apps can point out restaurants as you scan the street with your phone camera or even identify constellations when you point your ...
New field of "strain engineering" could open up areas of materials research
In the ongoing search for new materials for fuel cells, batteries, photovoltaics, separation membranes, and electronic devices, one newer approach involves applying and managing stresses within known materials ...
Researchers use microRNA to trap mutant viruses in the lab
Genetic engineering alters mosquitoes' sense of smell
In one of the first successful attempts at genetically engineering mosquitoes, Howard Hughes Medical Institute (HHMI) researchers have altered the way the insects respond to odors, including the smell of humans ...
Scientists discover RNA modifications in some unexpected places
The so-called central dogma of molecular biology—that DNA makes RNA which makes protein—has long provided a simplified explanation for how genetic information is deciphered and translated in living organisms.
Scientists sequence complete genome of E. coli strain responsible for food poisoning
(Phys.org) —Researchers at the University of California, San Diego have produced the first complete genome sequencing of a strain of E. coli that is a common cause of outbreaks of food poisoning in the ...
Scientists develop 'electronic nose' for rapid detection of C. diff infection
A fast-sensitive "electronic-nose" for sniffing the highly infectious bacteria C. diff, that causes diarrhoea, temperature and stomach cramps, has been developed by a team at the University of Leicester.
Prions can trigger 'stuck' wine fermentations, researchers find
A chronic problem in winemaking is "stuck fermentation," when yeast that should be busily converting grape sugar into alcohol and carbon dioxide prematurely shuts down, leaving the remaining sugar to instead ...
Genetics reveal effects of deadly frog fungus
(Phys.org) —A deadly fungus has decimated certain populations of amphibians globally for the past few decades, but scientists remain unclear about the exact mechanisms that lead to its disease.
Researchers find putting birds of different life-spans together can promote emergence of dangerous influenza strains
Possum poo study sheds light on human epidemics
A new study of the way bacteria spread amongst possums could shed light on the spread of human epidemics.
Research brings new control over topological insulator
An international team of scientists investigating the electronic properties of ultra-thin films of new materials – topological insulators (TIs) - has demonstrated a new method to tune their unique properties using strain.
