Long segments of RNA -- encoded in our DNA but not translated into protein -- are key to physically manipulating DNA in order to activate certain genes, say researchers. These non-coding RNA-activator molecules help create a loop of DNA to open up genes for transcription. They have a crucial role...

Organic electronics has already hit the market in smart-phone displays and holds great promise for future applications like flexible electroluminescent foils (a potential replacement for conventional light bulbs) or solar cells that convert sunlight to electricity. A reoccurring problem in this...

The UK's national synchrotron facility, Diamond Light Source, is now the first and only place in Europe where pathogens requiring Containment Level 3 – including serious viruses such as those responsible for AIDS, Hepatitis and some types of flu – can be analyzed at atomic and molecular level using...

Scientists have developed a new set of building blocks based on nanoparticles and DNA. Using these tools, scientists will be able to build -- from the bottom up, just as nature does -- new and useful structures. The research team has already built more than 200 different crystal structures with 17...

Doping dramatically alters the atomic-scale electronic structure of the parent of a high-temperature superconductor, with important consequences for the behavior of the current-carrying electrons, according to new research. The findings could potentially point to new ways to design superconductors...

To make fuel cells more economical, engineers want a fast and efficient iron-based molecule that splits hydrogen gas to make electricity. Researchers now report such a catalyst. It is the first iron-based catalyst that converts hydrogen directly to electricity. The result moves chemists and...

Physicists have demonstrated extremely flexible organic semiconductors that withstood multiple bending cycles in which the devices were rolled to a radius as small as 200 micrometers. The technology holds promise for making low-cost flexible electronics -- conceivably video displays that bend like...

Engineers have created a more efficient way to catch rainbows, an advancement in photonics that could lead to technological breakthroughs in solar energy, stealth technology and other areas of research. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/H...

Ever wonder why sand can both run through an hourglass like a liquid and be solid enough to support buildings? It's because granular materials -- like sand or dirt -- can change their behavior, or state. Researchers have found that the forces individual grains exert on one another are what most...

Physicists have developed nano-machines which recreate principal activities of proteins. They present the first versatile and modular example of a fully artificial protein-mimetic model system. These "bionic proteins" could play an important role in innovating pharmaceutical research. Fuente :...

Austromerope is a genus of forcepflies, whose representatives are rare and mostly restricted in distribution. It belongs to the family Meropeidae (Mecoptera) and was recently unexpectedly discovered in South America. The species found in Brazil was described as new to science and named Austromerope...

A controversial component of plastic bottles and canned food linings that have helped make a safer food supply has recently come under attack: bisphenol A. BPA has the potential to mimic estrogen if blood and tissue levels are high enough. Now, an analysis of almost 150 BPA exposure studies shows...

As people move more often and become more urbanized, skin color -- an adaptation that took hundreds of thousands of years to develop in humans -- may lose some of its evolutionary advantage, according to an anthropologist. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/Y...

The news sounds grim: Mounting scientific evidence indicates climate change will lead to more frequent and intense extreme weather that affects larger areas and lasts longer. However, we can reduce the risk of weather-related disasters with a variety of measures, according to scientists. Fuente :...
