Medical Xpress / Computer vision 'sees' our organs age at different rates
We tend to think of age as a linear progression marked by birthdays and milestones dictating when we can vote, drink, rent a car or pass beyond the crest of an arbitrary metaphorical hill. When scientists look at how organs ...
Phys.org / Bumblebees may self-medicate when exposed to fungal infections
There is an old saying that nature is the best medicine, and it turns out bumblebees might agree. A new study published in the journal Royal Society Open Science suggests that buff-tailed bumblebees (Bombus terrestris) may ...
Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...
Phys.org / Manganese's emission lines shine a light on galactic evolution
In a new study, a team of astronomers has identified wavelengths of light that could be useful for tracing the chemical evolution of the universe. Using computational modeling to simulate how electrons interact with manganese ...
Phys.org / Important role of plastid ion channels in plant stress response identified
When plants are attacked by herbivores or pathogens, they must respond rapidly while also preparing for potential future attacks. Calcium, a cellular second messenger, and the plant hormone jasmonic acid play important roles ...
Phys.org / Many space missions are searching for life beyond Earth, but are we prepared for the fallout if they succeed?
Microbes from space have fueled the plots of science fiction mainstays like "Project Hail Mary" and "The Andromeda Strain." But with more space missions launching each year, finding extraterrestrial life in a microbial form ...
Phys.org / Managing chronic conditions together may be key to longer lifespan, canine study finds
As dogs age, many develop more than one chronic health condition. New research from Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) shows those conditions can dramatically shorten a dog's lifespan, ...
Phys.org / Even small amounts of ocean plastic can affect petrel chicks
Ocean plastic pollution is accidentally on the menu for southern giant petrel chicks. Even small nibbles of it may affect their physiology during development, according to a study from the University of California, Davis, ...
Tech Xplore / A humanoid robot's social expressiveness may backfire when it makes mistakes
For robots to be successfully deployed in real-world environments, humans should trust them enough to cooperate with them. Some roboticists have been trying to determine whether users perceive robots that exhibit socially ...
Tech Xplore / Like a bird, this drone uses touch to grip branches and rest
Drones often hover in the air, noisy and whining. They can already be used for many tasks, but not when you need some quiet. Their batteries would also last longer if they could take a "rest" from time to time. But when a ...
Tech Xplore / Self-cleaning ocean carbon capture device removes mineral buildup while extracting CO₂
A new electrochemical process can rapidly strip dissolved carbon dioxide from ocean water while self-cleaning its own mineral buildup, according to a University of Michigan Engineering study published in Environmental Science ...
Medical Xpress / Silent artery plaques may appear in one in 13 adults before age 30
Atherosclerosis, the process underlying most cardiovascular diseases, begins long before the first symptoms appear. An international study shows that the disease can already be detected in apparently healthy young adults ...
