Tech Xplore / A robot that shifts its own weight to cross land, steps, and water
A robot meant to inspect a coastline, a flooded street or a wetland can't count on one kind of ground. It might need to crawl over a hard surface, climb a bank, scale a curb or a step, then slide into open water, often within ...
Phys.org / Plasma and electricity convert CO₂ into methanol, butane and other useful chemicals
Carbon dioxide (CO₂) can be harmful to the environment in large amounts but can be used in the production of fuels and other useful chemicals. Doing so isn't easy, though. Now, Yale researchers have developed a new way to ...
Medical Xpress / Scientists map brain's mysterious 'blue place' and discover longest neuron ever measured in a mouse
Deep in the brainstem sits a small but important cluster of neurons known as the locus coeruleus (LC), Latin for "blue place." It makes up a tiny fraction of the brain's cells but plays an important role by releasing the ...
Medical Xpress / Running marathons with type 1 diabetes can be safe, small study shows
New research to be presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy, from Sept. 28–Oct. 2 shows that, with the use of continuous glucose monitoring (CGM) devices, ...
Phys.org / Two spike 'keys' work together to let SARS-CoV-2 enter cells, study reveals
To enter cells, the COVID-19 virus fuses its surrounding membrane with the membrane of the target cell. This is where the fusion peptides of the spike protein come into play. These regions function as molecular keys that ...
Phys.org / Threatened bumblebee populations in England and Wales face severe genetic declines
A new study reveals that an important pollinator is rapidly losing genetic diversity in Britain. Moss carder bumblebees were once widespread across the UK, living in flower-rich meadows, marshes and heathlands, where they ...
Phys.org / Bringing ice sheets to life: Releasing a dynamic ice sheet modeling workflow for Australia's climate model
Ice sheets are fundamental components of the Earth system. Antarctica and Greenland, the two ice sheets currently on Earth, don't just affect their own regions: What happens on these vast masses of land ice influences weather, ...
Phys.org / Chimpanzees give youngsters the tools to learn tricky techniques
Two-thirds of a century after Jane Goodall observed "David Greybeard" break off a twig to fashion a fishing rod for termites, researchers following in her footsteps have found that adult chimpanzees in Senegal literally hand ...
Phys.org / Snow, monsoons and oceans shift Earth's center of mass each year, satellite tracking shows
Seasonal changes redistribute enough water around Earth to shift the planet's center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations ...
Phys.org / SpaceX prepares for first orbital flight of Starship rocket
SpaceX announced Tuesday that it was planning to send its flagship rocket, Starship, into orbit, a key step in its project to one day reach the moon or Mars.
Medical Xpress / From 7,000 drugs to one active against resistant strains: AI advances pneumonia drug repurposing
Streptococcus pneumoniae is a bacterial pathogen that causes life-threatening infections, including pneumonia and meningitis. These infections are commonly treated with antibiotics, but antibiotics are becoming less effective ...
Phys.org / Astronomy's decades-long quest to understand cosmic topology
If some aspects of cosmic topology turn out to be true, the idea that starships might voyage across the cosmos for hundreds of thousands of light-years without ever returning to the same neck of spacetime could be problematic.
