Phys.org / Why lethal mutations persist: Fruit fly study points to newly transferred jumping genes, not small DNA errors
Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a new study from Duke University. The findings, published in PLOS Biology, challenge decades of assumptions ...
Phys.org / Veterinarians in Japan and the UK view animal welfare through different cultural lenses
A new international survey reveals clear differences in how veterinarians and animal welfare scientists in Japan and the UK perceive animal welfare, particularly animal behavior. The findings are published in the journal ...
Medical Xpress / Real-time metabolic monitoring on a chip: What happens inside a cell can be measured instantly
In a significant advancement for lab-on-chip technology, IBEC researchers in the frame of the European project BLOC, have demonstrated the first integration of a benchtop nuclear magnetic resonance (NMR) spectrometer with ...
Phys.org / Probiotic sugar compound blocks norovirus from attaching to cells
Stopping viruses before they strike is a key challenge in public health. A research team led by Associate Professor Li Dan from the Department of Food Science and Technology at National University of Singapore's Faculty of ...
Medical Xpress / How voluntary exercise reshapes tryptophan metabolism through the gut microbiota
Something happens when a rat starts running. Not just the obvious things, the faster heart, the warming muscles, the rhythmic percussion of paws against the wheel. Something quieter. Something that begins in the coiled darkness ...
Medical Xpress / Quantitative imaging of beta cell mass may help with treatment for type 1 diabetes
In type 1 diabetes, the immune system starts to destroy insulin-producing beta cells in the pancreas. Progressive loss of these cells destabilizes the body's glucose levels and drives the course of the disease, so preserving ...
Phys.org / Strontium optical clock accurate to within 1 second over 30 billion years
Researchers from the University of Science and Technology of China have achieved a major breakthrough in optical clock technology, developing a strontium optical lattice clock with stability and uncertainty both surpassing ...
Medical Xpress / Inconsistent labeling and high doses found in delta-8 THC products
Cannabis products containing delta-8 THC have spiked in popularity in recent years, from gummies and brownies to vapes, pre-rolls, and tinctures. These products are frequently marketed as "legal" cannabis and often come in ...
Phys.org / How does snow gather on a roof? Simulation considers turbulence alongside snowflake size
No two snowflakes may be the same, but models that fail to take these variations into consideration often fall short when calculating the way snow accumulates on roofs. In Physics of Fluids, researchers from Harbin Institute ...
Medical Xpress / Scientists develop two-vaccine strategy to fight T cell lymphoma
T cell lymphomas are notoriously difficult to treat because immunotherapy, despite being one of the most effective therapies for treating cancer, can't easily distinguish cancerous T cells from healthy ones. Now, scientists ...
Phys.org / Subglacial weathering may have slowed planet's escape from snowball Earth
A new study led by researchers at the Earth-Life Science Institute (ELSI) at Institute of Science Tokyo challenges a long-standing assumption about Earth's most extreme ice ages. Using numerical geochemical models, the team ...
Phys.org / Moisture-powered polymers could make cleaning CO₂ from air more efficient
Over the past century, the amount of carbon dioxide in the atmosphere has increased dramatically. This rise has contributed to global warming and led to many harmful effects, including shifting weather patterns and more frequent ...
