Medical Xpress / Ketamine reduces anxiety and social withdrawal in stressed adolescent mice
Ketamine is a powerful anesthetic used for surgery and acute pain management. But in recent years, it has also gained a reputation as a potential treatment for certain mental health conditions like stress and anxiety. In ...
Phys.org / Laser-within-a-laser delivers MeV X-ray radiography in picoseconds
Lawrence Livermore National Laboratory's National Ignition Facility (NIF) is the hottest place on Earth for the briefest of moments during an experiment. Now, it can be one of the brightest places thanks to the Advanced Radiographic ...
Phys.org / Size-shifting nanoparticles successfully deliver mRNA medicine to the pancreas
In recent years, mRNA in lipid nanoparticles (mRNA–LNPs) has emerged as a promising strategy for treating numerous conditions, including COVID-19, various cancers and chronic genetic disorders. To date, this technology ...
Phys.org / Scientists rescue lost song of the critically endangered regent honeyeater
Scientists from The Australian National University (ANU) and the Taronga Conservation Society Australia have successfully restored the lost traditional song of one of Australia's most endangered birds, offering new hope for ...
Phys.org / Greenhouse gas fluxes in Everglades provide path for maximizing carbon capture via water management
The Florida Everglades is a complicated climate actor. The 1.5-million-acre wetland system remains a carbon sink, removing an average of 13.7 million metric tons of carbon dioxide from the atmosphere each year, but the system ...
Phys.org / Soil saturation data sharpens atmospheric river flood warnings, study of 71,000 storms finds
Atmospheric rivers carry unfathomable amounts of water across the sky, bringing moisture to drought-stricken regions like the Western U.S. But whether a particular incoming atmospheric river storm will result in disastrous ...
Phys.org / How a common fungus outsmarts drugs and our immune system
Our bodies are home to millions of fungi that, for the most part, are completely harmless. However, they can sometimes change from peaceful residents into dangerous invaders. One such is Candida parapsilosis, which normally ...
Phys.org / Single-celled organism becomes multicellular via three different pathways
Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger multicellular organism. A new ...
Phys.org / Isolating vesicle-cloaked viruses in city and hospital wastewater
Viruses such as human norovirus can travel in vesicles, small fluid-filled sacs that are like shipping containers for cells. Viruses hidden in these containers are often harder to detect and may be more infectious than free-floating ...
Medical Xpress / New diagnostic markers for multiple sclerosis discovered in cerebrospinal fluid
Researchers from the MPI of Biochemistry and the Technical University of Munich have discovered new diagnostic markers for multiple sclerosis (MS), a disease that affects 3 million people worldwide. Using mass spectrometry, ...
Tech Xplore / Is this your AI? ZEN framework cracks AI black box
Artificial intelligence (AI) systems power everything from chatbots to security cameras, yet many of the most advanced models operate as "black boxes." Companies can use them, but outsiders can't see how they were built, ...
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 ...
