The AA joins green groups in warning that recent changes in energy policy will harm the climate.
The first waves have peeled across an artificial surf lagoon built on the site of an old aluminium works on the edge of the Snowdonia National Park.
The spacecraft which made a spectacular landing on a comet last year has discovered a rich array of carbon compounds.
Scientists in South Korea develop a tiny robot - based on the water strider insect - that can jump on water
People who spend time watching fish swim in aquarium tanks could improve their physical and mental wellbeing, a study shows.
An aurora has been spotted around a brown dwarf more than 18 light years away, scientists report.
A new report says that highly valuable forests are being lost at an "unprecedented" rate from protected lands in Cambodia.
Scientists apply the paper art of kirigami to slice graphene, the world's thinnest material.
The virulent Xylella disease ravaging olive trees in Italy spreads to Corsica, prompting emergency measures.
A fly thought to be extinct in the UK is found in a Devon nature reserve.

A new study has concluded California accumulated a debt of about 20 inches of precipitation between 2012 and 2015 -- the average amount expected to fall in the state in a single year. The deficit was driven primarily by a lack of air currents moving inland from the Pacific Ocean that are rich in water vapor.
Working with yeast and worms, researchers found that incorrect gene expression is a hallmark of aged cells and that reducing such “noise” extends lifespan in these organisms.
The importance of a diet rich in fish oils -- now a billion dollar food-supplement industry -- has been debated for over half a century. A new study questions the relevance of fish oil-derived substances and their purported anti-inflammatory effects in humans.
Organic molecules never previously observed in comets, a relatively varied structure on the surface but a fairly homogeneous interior, organic compounds forming agglomerates rather than being dispersed in the ice: these are just some of first results provided by Philae on the surface of comet Churi. These in situ findings, which contain a wealth of completely new information, reveal several differences in comparison with previous observations of comets and current models.
In research that could lead to protective probiotics to fight the 'chytrid' fungus that has been decimating amphibian populations worldwide, researchers have grown bacterial species from the skin microbiome of four species of amphibians.

Are the same regions and even the same cells of the brain area called hippocampus involved in encoding and retrieving memories or are different areas of this structure engaged? This question has kept neuroscientists busy for a long time. Researchers at the Mercator Research Group "Structure of Memory" at RUB have now found out that the same brain cells exhibit activity in both processes. They have published their results in the journal "Hippocampus".

Since mice share 90 percent of our genes they play an important role in understanding human genetics. The European Mouse Disease Clinic (EUMODIC) brought together scientists from across Europe to investigate the functions of 320 genes in mice. Over half of these genes had no previously known role, and the remaining genes were poorly understood.

By studying the yeast used in beer- and bread-making, researchers at the University of Pittsburgh School of Medicine have uncovered the mechanism by which ancient proteins repair DNA damage and how their dysfunction could lead to the development of tumors. The findings, published online today in Nature Communications, could lead to new ways to tailor cancer therapies.


Associate Professor of Anthropology Ripan Malhi was a senior coauthor among an international team of researchers, who clarified the history of early migration to the Americas
The first human inhabitants of the Americas lived in a time thousands of years before the first written records, and the story of their transcontinental migration is the subject of ongoing debate and active research. A study by multi-institutional, international collaboration of researchers, published this week in Science (DOI: 10.1126/science.aab3884) presents strong evidence, gleaned from ancient and modern DNA samples, that the ancestry of all Native Americans can be traced back to a single migration event, with subsequent gene flow between some groups and populations that are currently located in East Asia and Australia.


This illustration shows how the protein receptor CD68 acts as a gateway for a malaria parasite (sporozoite) to enter the liver through a Kupffer cell, as revealed by Cha et...
Scientists uncover a port of liver entry for malaria parasites in a report published in The Journal of Experimental Medicine. If these results hold up in humans, drugs that target this entry protein might help prevent the spread of disease.
