Medical Xpress / People use the same neurons to see and imagine objects, study shows
Why can images of things we have seen seem so real when we later recall them from memory? A new study led by Cedars-Sinai Health Sciences University investigators sheds light on the answer. The research shows that the same ...
Phys.org / Non-producing oil and gas wells may emit microbial methane at rates 1,000 times higher than previously estimated
Microbial methane leaking from non-producing oil and gas wells is being emitted at rates about 1,000 times higher than previously estimated, according to a new study led by McGill University researchers. "Origins of Subsurface ...
Phys.org / From Asgard to Earth: Tiny tubes may reveal the moment complex life began
Stromatolites—and their close relatives, microbial mats—could be mistaken for what seems like a bunch of old dark rocks. But instead, they are dense, layered communities of microbes. Long before complex life such as animals ...
Phys.org / Deadly heat thresholds have already being crossed in six recent heat waves, study shows
Deadly heat wave events are occurring at temperatures and humidity levels previously thought to be survivable, according to a new paper by a team of international researchers, including from The Australian National University ...
Phys.org / Oxygen sensing helps explain why amphibians regenerate limbs but mammals cannot
Some animals can regrow lost body parts. Salamanders and frog tadpoles can rebuild entire limbs after amputation. Mammals cannot. For decades, biologists have tried to understand why. Now a team led by Can Aztekin at EPFL ...
Phys.org / Decoy molecules trick soil bacteria into attacking persistent pollutants without genetic engineering
In a study published in the Journal of Materials Chemistry A, Nagoya University researchers demonstrated that native soil bacteria, when treated with decoy molecules, can degrade non-native compounds, including persistent ...
Medical Xpress / Two new TB vaccines prove safe but fall short on broad protection in India trial
Two new vaccines to prevent tuberculosis (TB) are safe for use in adults and children, but they do not offer protection against all forms of TB, finds a large trial from India published by The BMJ.
Phys.org / New research shows how forests can prevent floods of all sizes
As large floods occur more frequently worldwide, many wonder what led to such devastating events. Greenhouse gas emissions from human activities, improper land management and forest removal increase flood frequencies and ...
Phys.org / Megawatt structured light arrives with 3,070 optical vortices in one array
Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase singularities. While they have been widely studied in recent decades, two fundamental limitations have ...
Phys.org / Wildlife trade increases pathogen transmission: What 40 years of data say about spillover
Hedgehogs, elephants, pangolins, bears or fennec foxes: many wild species are sold as pets, hunting trophies, for traditional medicine, biomedical research, or for their meat or fur. These practices, whether legal or illegal, ...
Phys.org / Keeping up with the phages: How V. cholerae neighbors swap defenses against viruses
Like most bacteria, Vibrio cholerae lives under constant attack from viruses. To survive, bacteria equip themselves with antiviral immune systems. Previous work has shown that V. cholerae carries a large genetic element called ...
Tech Xplore / Volcanic rock formula cuts cement emissions by two-thirds
Researchers have developed a volcanic rock formula that cuts carbon emissions by 67%, potentially offering an affordable alternative to increasingly scarce cement additives.
