Around 400,000 years ago, early humans hunted beavers as a food resource and possibly also for their pelts.The authors show that Middle Pleistocene humans systematically fed on these smaller animals and hence had a more varied diet than thus far known. Previously, the opinion was that that hominins of this age primarily subsisted on large mammals, such as bovids and rhinoceroses. Read more ›

New research identifies the class II PI3K-C2b protein, a member of the PI3 family of kinases, as one of the key regulators of blood vessels growth in humans and other mammals. Mutations in these family of proteins may lead to vascular malformations and the precise understanding of the whole process is instrumental in opening the door to new therapeutic approaches in the future.

Enzymes from microorganisms can produce hydrogen (H2) under certain conditions, which makes them potential biocatalysts for biobased H2 technologies. In order to make this hydrogen production efficient, researchers are trying to identify and eliminate possible limiting factors. These include formaldehyde, which occurs naturally as a metabolic product in cells and inhibits the particularly efficient [FeFe] hydrogenase. Read more ›

Fruit and vegetables contain a variety of plant natural products such as flavonoids, which give fruits their colour and are said to have health-promoting properties. Most plant natural products occur in nature as glycosides, i.e. chemical compounds with sugars. In order for humans to absorb the healthy plant natural products, the sugar must be split off in the intestine. Microorganisms in the intestinal flora help to speed up the process.... Read more ›

The largest review of papers for brain cancer that has spread from the lungs has found abnormalities in the brain cancer and for which licensed drugs could be clinically trialed to find out if they could treat the disease. The research also found genetic differences between smokers and non-smokers.

Cryptocurrency mining uses a significant amount of water amid the global water crisis, and its water demand may grow further. Researchers provides the first comprehensive estimate of Bitcoin's water use. He warns that its sheer scale could impact drinking water if it continues to operate without constraints, especially in countries that are already battling water scarcity, including the U.S. Read more ›

Scientists have developed an injectable or catheter-administered hydrogel with enhanced capabilities for treating hepatocellular carcinoma, a deadly form of liver cancer. This drug-eluting hydrogel can provide sustained, pH-dependent drug co-delivery and has capabilities for promoting anti-tumor immune responses. This reduces tumor cell proliferation and growth and offers a more efficient means of enabling tumor cell death.  Read more ›

While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. The simplest amino acid, carbamic acid, could have formed alongside stars or planets within interstellar ices. The findings could be used to train deep space instruments like the James Webb Space Telescope to search for prebiotic molecules in distant, star-forming regions of the universe. Read more ›

A novel pilot study incorporating mindfulness into exposure therapy shows promise for reducing symptoms of post-traumatic stress in cardiac arrest survivors. One in three survivors of cardiac arrest survivors develop PTSD, increasing their risk of mortality, yet no specific treatment has been developed for this population.  Read more ›

Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows -- gamma-ray bursts, or GRBs. The new unified model confirms that some long-lasting GRBs are created in the aftermath of cosmic mergers that spawn an infant black hole surrounded by a giant disk of natal material. Read more ›

Used lithium-ion batteries from cell phones, laptops and a growing number of electric vehicles are piling up, but options for recycling them remain limited mostly to burning or chemically dissolving shredded batteries. Researchers have improved on approaches that dissolve the battery in a liquid solution in order to reduce the amount of hazardous chemicals used in the process. This simple, efficient and environmentally-friendly solution overcomes the main obstacles presented by... Read more ›

Bees, wasps and ants belong to the Hymenoptera order and inject a whole cocktail of venomous ingredients when they sting. Despite their tremendous ecological and economic importance, little was previously known about the origins of their venom. Through extensive genomic studies, a team of researchers has now discovered that typical venomous components were already present in the earliest ancestors of Hymenoptera and must therefore have evolved before the stingers of...
