Kiwi bird genome sequenced

28-Jul-2015

Researchers of the University of Leipzig and the Max Planck Institute for Evolutionary Anthropology have now sequenced the genetic code of this endangered species and have identified several sequence changes that underlie the kiwi’s adaptation to a nocturnal lifestyle: They found several genes ...

Scientists identify schizophrenia's 'Rosetta Stone' gene

Breakthrough reveals gene's influence in a vulnerable period of the brain's development

27-Jul-2015

Scientists have identified a critical function of what they believe to be schizophrenia's "Rosetta Stone" gene that could hold the key to decoding the function of all genes involved in the disease.The breakthrough has revealed a vulnerable period in the early stages of the brain's development ...

Teeth reveal lifetime exposures to metals, toxins

24-Jul-2015

Is it possible that too much iron in infant formula may potentially increase risk for neurodegenerative diseases like Parkinson's in adulthood - and are teeth the window into the past that can help us tell? This and related theories were described in a "Perspectives" article authored by ...

Bringing back the magic in metamaterials

23-Jul-2015

A single drop of blood is teeming with microorganisms - imagine if we could see them, and even nanometer-sized viruses, with the naked eye. That's a real possibility with what scientists call a "perfect lens." The lens hasn't been created yet but it is a theoretical perfected optical lens made ...

Shallow fracking raises questions for water, new Stanford research shows

23-Jul-2015

The United States now produces about as much crude oil as Saudi Arabia does, and enough natural gas to export in large quantities. That's thanks to hydraulic fracturing, a mining practice that involves a rock-cracking pressurized mix of water, sand and chemicals.Ongoing research by Stanford ...

Fossil fuel emissions will complicate radiocarbon dating, warns scientist

22-Jul-2015

Fossil fuel emissions could soon make it impossible for radiocarbon dating to distinguish new materials from artefacts that are hundreds of years old. Carbon released by burning fossil fuels is diluting radioactive carbon-14 and artificially raising the radiocarbon 'age' of the atmosphere, ...

A most singular nano-imaging technique

Berkeley Lab's SINGLE provides images of individual nanoparticles in solution

20-Jul-2015

Just as proteins are one of the basic building blocks of biology, nanoparticles can serve as the basic building blocks for next generation materials. In keeping with this parallel between biology and nanotechnology, a proven technique for determining the three dimensional structures of individual ...

Better assessment of the health risks associated with mixtures of substances in food

EU research project EuroMix launched

17-Jul-2015

Foods can contain a variety of potentially harmful substances. These include environmental contaminants, pesticide residue as well as naturally occurring active ingredients. Assessing the health risks of mixtures of substances is difficult, since typically toxicological data is available only for ...

An elusive molecule -- finally revealed

A long-standing chemistry puzzle has been solved

16-Jul-2015

Scientists at the University of Arizona have discovered a mysterious molecule with a structure simple enough to make it into high school textbooks, yet so elusive that chemists have argued for more than a century over whether it even exists. And, like so many important discoveries in science, ...

A graphene-based sensor that is tunable and highly sensitive

14-Jul-2015

Many areas of fundamental research are interested in graphene owing to its exceptional characteristics. It is made of one layer of carbon atoms, which makes it light and sturdy, and it is an excellent thermal and electrical conductor. Despite its apparently limitless potential, however, few ...
