Medical Xpress / Psychedelics may aid PTSD recovery by repairing brain myelin, study finds
Post-traumatic stress disorder (PTSD) is not only characterized by strongly encoded traumatic memories, but also by disrupted coordination across brain networks. New research shows that treatment with psychedelic drugs triggers ...
Phys.org / Past climate change: First indicators show resilience in tropical life—up to 1.5°C
New geological data indicate that marine life is somewhat resilient to warming in the tropics. Chris Fokkema, Earth scientist at Utrecht University, discovered that tropical algae were largely unaffected by a number of periods ...
Phys.org / Tracing extracellular vesicles' journey from cancer cells to urine
Cancer cell-derived small extracellular vesicles (sEVs) can travel from distant tumors through the bloodstream and kidneys and be excreted into urine, as reported by researchers at Science Tokyo. Using sophisticated molecular ...
Phys.org / Elephants avoid humans far more than baboons, waterbucks or antelopes
Wild animal species respond very differently to human development, and as a result, they use ecological corridors in agricultural and urban areas in distinct ways. This emerges from research in Botswana by ecologist Marlee ...
Phys.org / Why conversation is more like a dance than an exchange of words
Think about the last time you told a story to a friend. You probably adjusted it halfway through. You saw their eyebrows lift. You noticed them lean in, or glance away. You clarified a detail. You sped up the ending. That ...
Phys.org / Life forms can planet hop on asteroid debris—and survive
Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain hardy bacterium easily ...
Tech Xplore / How hawks slip through tight gaps: A flight stability trick drones could copy
Birds have an ability to fly through obstacles by shifting their shape in flight, which is difficult to reproduce in uncrewed aerial vehicles, commonly known as UAVs or drones. A new study from researchers at the University ...
Phys.org / Using individual atoms to achieve fossil-free chemistry
Every chemical reaction faces a barrier: For substances to react with one another, it is first necessary to supply energy. In many cases, this energy barrier is low—such as when striking a match. For many key reactions ...
Phys.org / Did plants nearly wipe out all marine life on Earth—twice?
UC College of Arts and Sciences Professor Thomas Algeo has been studying the planet's five major mass extinctions since the Ordovician Period, when global sea levels were much higher than today. In a paper published in Nature ...
Phys.org / Poking a nanostring: Scientists uncover energy cascades in tiny resonators
Scientists at TU Delft have designed a nanostring that, when poked, doesn't lose its energy to the environment immediately. Instead, the energy leaks out within the string, triggering a cascade of distinct vibrational modes. ...
Phys.org / NASA rules out asteroid smashup on the moon in 2032
Here's one less thing to worry about—or to look forward to: NASA has ruled out any chance that an asteroid called 2024 YR4 will hit the moon in 2032. Last year, the uncertainty surrounding the space rock's orbital path ...
Medical Xpress / Blood-based marker opens up perspectives for cancer diagnostics
Metastatic prostate cancer is currently associated with high morbidity and mortality rates. In addition, patients respond very differently to standard treatments such as hormone therapy or radiation therapy. Reliable markers ...
