Phys.org / Biohybrid microrobots repair spinal cord by combining stem cells with magnetoelectric nanoparticles
Spinal cord injuries can have devastating consequences for those affected. Nerve cells in the spinal cord rarely regenerate naturally, while scarring often prevents the regrowth of nerve fibers. Modern therapies attempt to ...
Phys.org / Ötzi the Iceman and his microbiome—a 5,300-year-old relationship
Researchers at Eurac Research have obtained a detailed picture of the microbial community associated with Ötzi, Europe's oldest known natural human mummy. The study provides insights into a complex microbiome, ranging from ...
Phys.org / Overarming America: Game theory explores how fear and social pressure drive gun purchases
A Dartmouth College study is the first to map the interplay of personal choice and social networks that has led to the United States being one of the world's most heavily armed countries, with 120 firearms for every 100 people. ...
Medical Xpress / Long-hidden 'junk DNA' regions may help explain cancer-linked genome instability
Many repetitive regions of the genome have been considered "junk DNA" because the available technologies did not allow them to be studied at sufficient resolution. This is the case for the SST1/NBL2 macrosatellites, considered ...
Medical Xpress / New hantavirus sequencing tool maps whole genomes from hard-to-test samples
Infections by hantaviruses are rare but dangerous, killing 30–40% of infected people. When cases occur, public health officials need rapid, detailed information about the virus to identify the strain and its origin, so they ...
Phys.org / Nitric oxide overload jams plant immune signals, researchers find
A new study from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment (CAFE) helps explain how plants can lose track of their own disease warnings.
Medical Xpress / How cells fight infection from the inside: Newly identified ADX pathway may broaden understanding of immunity
When thinking of the immune system, most people imagine white blood cells putting up a fight against invading germs in the bloodstream. But now, in research published in Molecular Cell, scientists detail a separate but equally ...
Science X / Why your old playlists still hit hard even if you never press play
Past research has shown that music is a significant source of nostalgia that boosts well-being and social bonds. In fact, hearing a tune from your youth is a powerful cue for rich, vivid memories. But what about hearing nothing ...
Phys.org / Plants boost carbon uptake through water efficiency, not heat adaptation, global analysis reveals
An international team of scientists has discovered that plants are not responding to global warming in the way researchers long assumed. Scientists have expected that ecosystems would keep pace with warming by raising the ...
Medical Xpress / Motherhood leaves lifelong brain marks via dopamine-linked epigenetic switch, mouse study suggests
Becoming a mother changes the brain not just temporarily, but for life. Pregnancy and the postpartum period trigger lasting changes in the maternal brain through the brain chemical dopamine, producing long-term benefits to ...
Phys.org / Atomic reshuffle leads to record-breaking catalysts for hydrogen production
Researchers have discovered that atoms can be mixed, separated, and recombined within the same experiment, providing a pathway to a record-breaking catalyst for green hydrogen production. In their study, the team created ...
Phys.org / Not too sunny, not too shady, just right for Japanese macaques
As climate change alters the temperatures of animal habitats, it seems natural that endotherms, warm-blooded animals, would prefer to hang out in the shade during hot weather. The use of microhabitats in the sun and shade ...
