Phys.org / Largest canine gut microbiome catalog reveals hundreds of new bacterial strains
Researchers at the Waltham Petcare Science Institute in the UK recently revealed a complete taxonomic and functional catalog of the canine gut microbiome after analyzing samples from 107 healthy dogs across the U.S. and Europe. ...
Phys.org / Key protein can restore aging neural stem cells' ability to regenerate
Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have found that a key protein can help to regenerate neural stem cells, which may improve aging-associated decline in neuronal ...
Phys.org / Bird retinas function without oxygen—solving a centuries-old biological mystery
Neural tissue normally dies quickly without oxygen. Yet bird retinas—among the most energy-demanding tissues in the animal kingdom—function permanently without it. This may be relevant in future treatment of stroke patients.
Phys.org / Massive cloud with metallic winds discovered orbiting mystery object
Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months. This discovery, made with the Gemini South telescope in Chile, one half of the International Gemini ...
Phys.org / Massive black hole mystery unlocked by researchers
It's one of astronomy's great mysteries: how did black holes get so big, so massive, so quickly. An answer to this cosmic conundrum has now been provided by researchers at Ireland's Maynooth University (MU) and reported today ...
Phys.org / Prehistoric tool made from elephant bone is the oldest discovered in Europe
A remarkable prehistoric hammer made from elephant bone, dating back nearly half a million years ago, has been uncovered in southern England and analyzed by archaeologists from UCL and the Natural History Museum, London.
Phys.org / Grains of sand prove people—not glaciers—transported Stonehenge rocks
Ask people how Stonehenge was built and you'll hear stories of sledges, ropes, boats and sheer human determination to haul stones from across Britain to Salisbury Plain, in south-west England. Others might mention giants, ...
Phys.org / Kenya's big cats under pressure: Cattle are pushing lions away
In the Kenyan savanna, lions and livestock essentially live in shifts: Cattle graze during the day and are enclosed at night when lions are active.
Phys.org / Old diseases return as settlement pushes into the Amazon rainforest
Human activity continues to expand ever further into wild areas, throwing ecology out of balance. But what begins as an environmental issue often evolves into a human problem.
Phys.org / EAST achieves new plasma confinement regime using small 3D magnetic perturbations
A research group has achieved a new plasma confinement regime using small 3D magnetic perturbations that simultaneously suppress edge instabilities and enhance core plasma confinement in the Experimental Advanced Superconducting ...
Phys.org / Optical technique reveals hidden magnetic states in antiferromagnets
Imagine computer hardware that is blazing fast and stores more data in less space. That's the promise of antiferromagnets, magnetic materials that do not interfere with each other and can switch states at high speed, opening ...
Phys.org / Dredging sand and silt has consequences for the North Sea
Through sand extraction and the disposal of dredged harbor silt, about 200 million tons of sediment are relocated every year in the coastal waters of the North Sea. The Wadden Sea is particularly strongly affected. This is ...
