Pathogen-fighting immune cells called tissue-resident memory CD8 T cells (TRM cells) go through a surprising transformation -- and relocation -- as they fight infections in the small intestine.
Fossil discovery in the Geiseltal Collection: Researchers identify unique bird skull
Around 45 million years ago, a 4.6 feet-tall (1.40 meters) flightless bird called Diatryma roamed the Geiseltal region in southern Saxony-Anhalt. An international team of researchers report on the bird's fully preserved skull. The fossil was unearthed in the 1950s in a former lignite mining area in the Geiseltal in...
A Green Fuels Breakthrough: Bio-Engineering Bacteria to Become ‘Hydrogen Nanoreactors’
Researchers at the University of Oxford’s Department of Engineering Science have made major advances towards realising green hydrogen – the production of hydrogen by splitting water, powered by renewable energy.
Warmer, Greener Arctic Becoming a Source of Heat-Trapping Gas
As the northern latitudes warm, ice is melting and vegetation is growing more abundant.
‘Buzz me in:’ Bees Wearing Itty Bitty QR Codes Reveal Hive Secrets
Several hundred bees in rural Pennsylvania and rural New York are sporting tiny QR codes on their backs.
Fighting experience plays key role in brain chemical’s control of male aggression
Like humans, mice will compete over territory and mates, and show increased confidence in their fighting skills the more they win. At first, a brain chemical called dopamine is essential for young males to master this behavior. But as they gain experience, the chemical grows less important in promoting aggression,...
Robots Should Be Repurposed Rather Than Recycled to Combat Rising Scale of E-waste, Scientists Warn
The robotics industry should be creating robots that could be reprogrammed and repurposed for other tasks once its life span is completed, University of Bristol and University of West England researchers have advised.
Scientists identify neurons in mice that, once activated, can change body’s metabolic rate, induce hibernation-like state
A new study has identified a group of neurons that, when activated, can induce a hypometabolic state, akin to hibernation. The discovery could have far-reaching implications for conditions like obesity, cardiometabolic diseases, and even for space travel. The research team found that these neurons regulate key aspects of the brain-heart-gut...
Dolphins use a ‘fat taste’ system to get their mother’s milk
Juvenile dolphins were found to have specialized receptors for fatty acids on their tongues, offering new insights into their growth and feeding habits.
Can DNA-nanoparticle motors get up to speed with motor proteins?
DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is converted into mechanical motion by biasing the Brownian motion. The DNA-nanoparticle motor uses the 'burnt-bridge' Brownian ratchet mechanism. In this type...
