Phys.org / Exceptionally preserved 551-million-year-old site suggests Avalon biota lasted longer
Researchers studying the soft-bodied Ediacaran biotas of the world generally accept that there are three distinct assemblages. The 575–560-million-year-old (Ma) Avalon Assemblage is best known from the Ediacaran of Newfoundland, ...
Phys.org / Enhanced rock weathering is not yet a reliable climate protection measure, say researchers
Most countries will not achieve climate neutrality through greenhouse gas emission reductions alone; carbon sinks are also needed to offset unavoidable emissions. Researchers are discussing technical solutions, such as applying ...
Phys.org / Forget flatfooted lumbering T. rex. New research shows it walked on tiptoes
Powerful, fierce and the king of the Cretaceous world, Tyrannosaurus rex was the ultimate apex predator. But it was also surprisingly dainty on its feet, according to new research. Findings published in the journal Royal ...
Phys.org / Nanoparticle system shows promise for delivering mRNA to prevent type 1 diabetes
Research on preventing type 1 diabetes often focuses on limiting the autoimmune response that destroys the body's ability to produce its own insulin. A new technology developed by scientists at the University of Chicago takes ...
Medical Xpress / HIV can develop resistance to blockbuster antiviral lenacapavir—but at a cost to the virus
Long-acting antiviral medications are transforming HIV prevention and care, requiring only minimalistic dosing. But as the use of lenacapavir expands, scientists are probing a critical question: If the virus evolves resistance, ...
Medical Xpress / New record: Laser for surgery cuts bone deeper than before
Lasers cut precisely and without contact—ideal for surgery. The problem is that in hard tissues such as bone, they are too slow and do not cut deep enough. Researchers at the University of Basel have now demonstrated a ...
Phys.org / A new, useful absorption limit for ultra-thin films
Ultrathin, conductive films such as those made of graphene are widely used in modern optoelectronic devices, but it has been thought that their efficacy is fundamentally limited: they can absorb at most half of the incident ...
Tech Xplore / A more durable direct air capture approach: Electrified mineral-based system resists oxygen and humidity
Many governments and businesses worldwide have been trying to devise effective initiatives aimed at mitigating climate change and global warming. So far, their primary focus has been to reduce the emission of carbon dioxide ...
Phys.org / How many bee species exist? New global count puts the total near 26,000
The world has far more bees than anyone realized. Scientists have, for the first time, estimated just how many species of bees are out there on a global scale, offering a clearer look at how these vital pollinators are distributed ...
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 / Finding the honey bee dance floor: New method shows how it moves within the hive
When honey bees find a good source of food, they return to their hive and perform a waggle dance. It consists of a series of movements that communicate the direction and distance to nectar, pollen or water relative to the ...
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 ...
