Microbes may just be the next diet craze. Researchers have programmed bacteria to generate a molecule that, through normal metabolism, becomes a hunger-suppressing lipid. Mice that drank water laced with the programmed bacteria ate less, had lower body fat and staved off diabetes -- even when fed a high-fat diet -- offering a potential weight-loss strategy for humans.

If every new car made in the United States had a built-in blood alcohol level tester that prevented impaired drivers from driving the vehicle, how many lives could be saved, injuries prevented, and injury-related dollars used for something else?

The functional differences between autistic and non-autistic brains have been isolated for the first time, following the development of a new methodology for analyzing MRI scans.

Adapting to climate change could have profound environmental repercussions, according to a new study from the University of East Anglia.

Research in Nature Climate Change reveals that adaptation measures have the potential to generate further pressures and threats for both local and global ecosystems.

Lead researcher Dr Carlo Fezzi, from UEA's School of Environmental Sciences, said: "Climate change is a just a little bit more complicated than we previously thought. We need to take into account not only the direct impact of climate change, but also how people will respond to such change - the impact of adaptation.

"This is a whole new dimension to the climate change adaptation debate."

The first blood test for osteoarthritis could soon be developed, thanks to research by the University of Warwick.

The research findings could potentially lead to patients being tested for osteoarthritis and diagnosed several years before the onset of physical symptoms.

Conducted by the University's Medical School, the research identified a biomarker linked to both rheumatoid and osteoarthritis.

Whilst there are established tests for rheumatoid arthritis (RA), the newly identified biomarker could lead to one which can diagnose both rheumatoid arthritis and osteoarthritis (OA).

A plant scientist from The Australian National University (ANU) has called for the United Nations to guarantee free and open access to plant DNA sequences to enable scientists to continue work to sustainably intensify world food production.

Dr Norman Warthmann, a plant geneticist at the ANU Research School of Biology, has lodged a submission with the UN, which is currently considering issues to include in its 2015 Global Sustainable Development Report.

Food security depends on an acceleration in plant breeding, which could be threatened by private companies restricting access to genomic information, Dr Warthmann said.
