Environment Secretary Owen Paterson is set to reopen the debate about genetic modification by calling for the reform of crop licensing at EU level.
The plights of the world's threatened birds show the value of investing in conservation, according to an international report.
Mars' atmosphere could have been rich in oxygen four billion years ago - well before Earth's air became augmented with the gas.
A rodent that never gets cancer could hold the key to preventing or treating malignant tumours, say scientists.
The Cassini probe in orbit around Saturn is going to picture the ringed planet in a special photo that also includes a distant Earth.
The quality of a performance does not drive the amount of applause an audience gives, a study suggests.
Researchers have revealed new information about the latest strain of type A influenza, known as H7N9.
How long ago did bacteria invade the one-celled ancestors of plants and animals to become energy-producing mitochondria and photosynthesizing chloroplasts? Researchers developed a statistical way to analyze the variation in genes common to mitochondria, chloroplasts and the eukaryotic nucleus to more precisely date these events. They found that the cyanobacterial invasion of plants took place millions of years more recently than thought.
Using data gathered by NASA's Lunar Reconnaissance Orbiter mission, scientists believe they have solved a mystery from one of the solar system's coldest regions -- a permanently shadowed crater on the moon. They have explained how energetic particles penetrating lunar soil can create molecular hydrogen from water ice. The finding provides insight into how radiation can change the chemistry of water ice throughout the solar system.
Slipping bacteria some silver could give old antibiotics new life, scientists report. This could pave the way for new therapies for drug-resistant and recurrent infections.
Improved methods for breaking down cellulose nanofibers are central to cost-effective biofuel production and the subject of new research. Scientists are investigating the unique properties of crystalline cellulose nanofibers to develop novel chemical pretreatments and designer enzymes for biofuel production from cellulosic -- or non-food -- plant-derived biomass.

The Max Planck Society selected a new president, chemist Martin Stratmann. And Science interviews David Altshuler of the Broad Institute, who is leading the planning to create a global alliance of research, health care, and patient advocacy organizations to help researchers securely share genome sequences and clinical information.
A student filmmaker won an award from the Sloan Foundation for his science-based screenplay about fatal insomnia.
Last week's disclosures that the U.S. National Security Agency (NSA) is collecting cell phone records and Internet data came as no surprise to experts in network analysis, who say that the type of data crunching NSA is engaged in—identifying social groups from connections among people—is business as usual at several private companies.
