The genomic studies of wheat sheds new light on crop adaptation and domestication
Chinese scientists report the latest genomic studies of wheat, shedding new light on crop adaptation and domestication.

Gladstone scientists discover that DNA damage occurs as part of normal brain activity
Scientists at the Gladstone Institutes have discovered that a certain type of DNA damage long thought to be particularly detrimental to brain cells can actually be part of a regular, non-harmful process.

Nanowire solar cells raise efficiency limit
Scientists from the Nano-Science Center at the Niels Bohr Institut, Denmark and the Ecole Polytechnique Fédérale de Lausanne, Switzerland, have shown that a single nanowire can concentrate the sunlight up to 15 times of the normal sun light intensity.

Losing wetlands to grow crops
Getting enough to eat is a basic human need -- but at what cost to the environment?

Catalyst in a teacup: New approach to chemical reduction
Taking their inspiration from Nature, scientists at the University of New South Wales in Sydney have developed a new method for carrying out chemical reduction - an industrial process used to produce fuels and chemicals that are vital for modern society.

Amniotic fluid stem cells repair gut damage
Stem cells taken from amniotic fluid were used to restore gut structure and function following intestinal damage in rodents, in new research published in the journal Gut.

Parkinson's drug helps older people to make decisions
A drug widely used to treat Parkinson's disease can help to reverse age-related impairments in decision making in some older people, a study from researchers at the Wellcome Trust Centre for Neuroimaging has shown.

Surprises in the South polar vortex in Venus' atmosphere
The astronomers in the UPV/EHU's Planetary Science Group have published, on-line in the prestigious journal Nature Geoscience, a study of the atmospheric vortex of the south pole of Venus.

Study finds molecular 'signature' for rapidly increasing form of esophageal cancer
New research led by scientists at Dana-Farber Cancer Institute, the Broad Institute, and other research centers, may offer clues to why rates of esophageal adenocarcinomas (EAC) have risen so sharply.
