Study identifies new findings on implant positioning and stability during robotic-assisted knee revision surgery

An innovative study explores the use of robotic-assisted joint replacement in revision knee scenarios, comparing the pre- and post-revision implant positions in a series of revision total knee arthroplasties (TKA) using a state-of-the-art robotic arm system.

Chemists create a 2D heavy fermion

Researchers have synthesized the first 2D heavy fermion. The material, a layered intermetallic crystal composed of cerium, silicon, and iodine (CeSiI), has electrons that are 1000x heavier and is a new platform to explore quantum phenomena.

The surface knows what lies beneath: Physicists show how to detect higher-order topological insulators

Just like a book can't be judged by its cover, a material can't always be judged by its surface. But, for an elusive conjectured class of materials, physicists have now shown that the surface previously thought to be 'featureless' holds an unmistakable signature that could lead to the first definitive observation.

Amnesia caused by head injury reversed in early mouse study

A mouse study designed to shed light on memory loss in people who experience repeated head impacts, such as athletes, suggests the condition could potentially be reversed. The research in mice finds that amnesia and poor memory following head injury is due to inadequate reactivation of neurons involved in forming memories.

'Smart glove' can boost hand mobility of stroke patients

This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.

Chasing the light: Study finds new clues about warming in the Arctic

The Arctic, Earth's icy crown, is experiencing a climate crisis like no other. It's heating up at a furious pace -- four times faster than the rest of our planet. Researchers are pulling back the curtain on the reduction of sunlight reflectivity, or albedo, which is supercharging the Arctic's warming.

For surgery patients, AI could help reduce alcohol-related risks

Using artificial intelligence to scan surgery patients' medical records for signs of risky drinking might help spot those whose alcohol use raises their risk of problems during and after an operation, a new study suggests. The AI record scan tested in the study could help surgery teams know in advance which patients might need more education about such risks, or treatment to help them reduce their drinking or stop drinking for a period of time before and after surgery.

Few older adults use direct-to-consumer health services; Many who do don't tell their regular provider

A new poll finds that 1 in 10 people aged 50-64 have used direct-to-consumer services, and most have gotten prescriptions from them; 4 in 10 people in this age group may be interested in future use.

Even the oldest eukaryote fossils show dazzling diversity and complexity

The sun has just set on a quiet mudflat in Australia's Northern Territory; it'll set again in another 19 hours. A young moon looms large over the desolate landscape. No animals scurry in the waning light. No leaves rustle in the breeze. No lichens encrust the exposed rock. The only hint of life is some scum in a few puddles and ponds. And among it lives a diverse microbial community of our ancient ancestors.

Scientists identify how dietary restriction slows brain aging and increases lifespan

Restricting calories is known to improve health and increase lifespan, but much of how it does so remains a mystery, especially in regard to how it protects the brain. Scientists have now uncovered a role for a gene called OXR1 that is necessary for the lifespan extension seen with dietary restriction and is essential for healthy brain aging.

Catalytic combo converts CO2 to solid carbon nanofibers

Scientists have developed a way to convert carbon dioxide (CO2), a potent greenhouse gas, into carbon nanofibers, materials with a wide range of unique properties and many potential long-term uses. Their strategy uses tandem electrochemical and thermochemical reactions run at relatively low temperatures and ambient pressure and could successfully lock carbon away to offset or even achieve negative carbon emissions.
