Berkeley Lab scientists generate electricity from viruses
Berkeley Lab scientists have developed a way to generate power using harmless viruses that convert mechanical energy into electricity.

Reducing post-traumatic stress after ICU
Women are more likely to suffer post-traumatic stress than men after leaving an intensive care unit (ICU), finds a new study published in BioMed Central's open access journal Critical Care.

Excess weight in pregnant women can have negative implications for offspring
That overweight during pregnancy can lead to overweight children and adolescents has been known for some time, but new research at the Hebrew University of Jerusalem and in the US indicates that excess weight before and during pregnancy can have long-lasting health consequences for the offspring of such mothers even later in life.

Wasted milk is a real drain on our resources, study shows
Milk poured down Britain's kitchen sinks each year creates a carbon footprint equivalent to thousands of car exhaust emissions, research shows.

You can't play nano-billiards on a bumpy table
There's nothing worse than a shonky pool table with an unseen groove or bump that sends your shot off course: a new study has found that the same goes at the nano-scale, where the

BGI reports the completed sequence of foxtail millet genome
BGI, the world's largest genomics organization, in cooperation with Zhangjiakou Academy of Agricultural Science, has completed the genome sequence and analysis of foxtail millet, the second-most widely planted species of millet.

Virus 'barcodes' offer rapid detection of mutated strains
Researchers at the University of Leeds are developing a way to 'barcode' viral diseases to rapidly test new outbreaks for potentially lethal mutations.

Time, place and how wood is used are factors in carbon emissions from deforestation
A new study from the University of California, Davis, holds implications for the impact of biofuels production on deforestation and greenhouse gas emissions.

New study discovers powerful function of single protein that controls neurotransmission
Scientists at Weill Cornell Medical College have discovered that the single protein -- alpha 2 delta -- exerts a spigot-like function, controlling the volume of neurotransmitters and other chemicals that flow between the synapses of brain neurons.

Research maps the city's heat
Steel - the traditional industry for which the UK city of Sheffield is so well known - could help provide a green alternative for heating the city's homes and businesses, finds a new study published today.

Americans support national clean-energy standard
The average US citizen is willing to pay 13 percent more for electricity in support of a national clean-energy standard, according to Yale and Harvard researchers in Nature Climate Change.

Researchers map path to quantum electronic devices
A team of Duke University engineers has created a master

DNA replication protein also has a role in mitosis, cancer
University of North Carolina School of Medicine scientists have discovered that a protein known as Cdt1, which is required for DNA replication, also plays an important role in a later step of the cell cycle, mitosis.

Discovery of plant proteins may boost agricultural yields and biofuel production
Scientists at the Salk Institute for Biological Studies and Iowa State University discovered a family of plant proteins that play a role in the production of seed oils, substances important for animal and human nutrition, biorenewable chemicals and biofuels.

New type of retinal prosthesis could better restore sight to blind, Stanford study says
Using tiny solar-panel-like cells surgically placed underneath the retina, scientists at the Stanford University School of Medicine have devised a system that may someday restore sight to people who have lost vision because of certain types of degenerative eye diseases. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
