Medical Xpress / Doctors urge caution regarding elective MRI in new editorial
According to leading radiologists, elective MRI screenings are not recommended and can do more harm than good. In a new editorial in JAMA, experts from the University of Michigan Health and the University of Wisconsin School ...
Phys.org / CPR simulator for space use tracks the differences of blood flow in reduced gravity
The new focus on manned missions to the moon and Mars presents countless pressing challenges, including keeping humans alive in hostile environments. What happens when an astronaut or space tourist has a cardiac emergency ...
Phys.org / How a newly discovered organelle could help reduce cow methane emissions
When cows burp, they send a substantial amount of methane gas into the air, which makes them a leading contributor to greenhouse gas emissions. According to research published in the journal Science, a newly discovered hydrogen-producing ...
Phys.org / Locked in stone for 210 million years, this newly identified crocodile cousin was built to crush larger prey
On a fateful day 210 million years ago, two crocodile cousins about the size of jackals stood side-by-side amid the low ferns of a humid riverbank that would one day become northern New Mexico. One of the crocs, Hesperosuchus ...
Tech Xplore / Beyond borders: Metaverse manufacturing envisions AI-linked local production built on digital twins
Over the past decades, technological advances have fueled great innovation in a wide range of fields. Emerging and rapidly developing technologies, such as artificial intelligence (AI) systems, three-dimensional (3D) and ...
Phys.org / A skull full of surprises: Discovering the evolutionary secrets of fish brains
A new study in Proceedings of the Royal Society B reveals the surprising neurological landscape of fish brains. Harvard researchers map the internal structures of ray-finned fishes' brains in 3D detail, discovering brain ...
Tech Xplore / Vanadium batteries could stabilize power grids and help prevent blackouts in Ecuador
The transition toward renewable energy is redefining the operation of power systems worldwide. However, this shift brings a growing technical challenge: the loss of grid stability. Unlike conventional power plants, renewable ...
Phys.org / Data fusion provides a high-definition look at Mars' temperature maps
In-situ Resource Utilization (ISRU) is our best bet for "living off the land" for a future Martian base, but tracking down those resources is no easy task. As of now, we have two options—send a rover to a specific location ...
Phys.org / Timor green pigeon 'likely to go extinct' without urgent action, according to scientists
The Timor green pigeon, which is under pressure from hunting and habitat loss, is at serious risk of extinction and should be uplisted to Critically Endangered, according to a new study from researchers at Charles Darwin ...
Medical Xpress / How the senses intertwine to help store new speech patterns
We don't usually realize it, but every word we speak depends on a series of complex brain processes working behind the scenes. One important part of this is speech motor learning, the brain's ability to learn and remember ...
Phys.org / Polymer 'bristles' could help repel proteins—and germs—from surfaces in medical settings
A non-toxic coating developed by researchers at University of Toronto Engineering prevents proteins from sticking to surfaces—potentially offering a new tool in the fight against hospital-acquired infections.
Medical Xpress / How changes to proteins can alter drug interactions for new precision therapies
Inside every human cell, proteins are constantly being tagged with small chemical modifications after they're produced. Known as post-translational modifications, or PTMs, these can change how a protein folds, where it travels ...
