Phys.org / 10,000 years of wheat and barley selection reveal shared climate-adaptation genes
Research teams from INRAE, the University of Clermont Auvergne and the CNRS have reconstructed 10 ancient genomes (paleogenomes) that are the common ancestors of 84 botanical species of agronomic interest. Their work makes ...
Medical Xpress / Brain aging may be detected decades before symptoms appear, with links to gut health
A new UCLA study has found a connection between how quickly the brain ages and the bacteria and chemical byproducts found in the gut, offering a clue to what drives brain aging long before symptoms appear.
Phys.org / Compost microbe yields enzyme that tackles polyurethane foam and nylon
Researchers from Aarhus University and the Danish Technological Institute have taken a new approach in the search for enzymes capable of breaking down some of the most difficult types of plastic to recycle. They collected ...
Phys.org / New measure captures how scientists' identities shift across academic disciplines
Does the academic discipline of a scientist's doctorate accurately capture their disciplinary affiliation decades later? Consider a scientist who earned a doctorate in physics 25 years ago who now studies climate change, ...
Phys.org / Microplastics fall across rural Switzerland, adding over 200 tons yearly to land and water
Loose fibers from functional clothing, discarded PET bottles or abandoned packaging: When such plastic materials enter the environment, they often persist there for a long time. UV radiation, precipitation and ozone cause ...
Phys.org / When will your glacier disappear? New website lets users explore risks worldwide
When will the glacier in your valley disappear? Will the glacier you visited as a child still exist in 2050? And how much difference would limiting global warming make?
Phys.org / Scientists discover a strange new form of ice that could help explain the interiors of Neptune and Uranus
Scientists have discovered that there is ice deep inside planets like Neptune and Uranus and want to find out what form it takes and how it behaves. They cannot dig for it and transport it all the way back to Earth, so they ...
Phys.org / Bite, buzz, release: How bees make flowers give up their pollen
Life is not always easy for a bee: Not all plants place their pollen outside. Some flowers have to be set to vibrating before the pollen can get out of their tube-like stamens. Certain bee species have developed a special ...
Medical Xpress / Blood and gene tests predict Alzheimer's symptoms three to six years ahead
Columbia University researchers have identified a way to help predict when people at high risk of developing Alzheimer's are likely to develop their first symptoms, a finding that could help physicians decide when to prescribe ...
Phys.org / Unusual bonds reorganize structure and magnetism in vanadium material
While chemical bonds usually determine the structure and properties of a material, bonds between neighboring metal atoms can also change as temperature or other conditions change. These changes can lead to unusual electronic ...
Phys.org / Shapeshifting plant roots rely on a balance of anatomy, metabolism, and microbes to maximize survival
Scientists have identified the mechanisms that allow plants to change their root anatomy to maximize survival when nutrients are scarce. The findings could pave the way for developing new ways to improve beneficial plant-microbe ...
Medical Xpress / New findings link obesity to loss of natural breast cancer protection
A research team at Huntsman Cancer Institute at the University of Utah (the U) has found that obesity prevents a biological process that kills cancerous cells, revealing a possible reason obesity is a risk factor for breast ...
