Inflatable robotic hand gives amputees real-time tactile control
High-speed camera captures a water jet’s splashy impact as it pierces a droplet
The results may help engineers develop a way to inject drugs without needles.
Squirting a jet of water through a drop of liquid may sound like idle fun, but if done precisely, and understood thoroughly, the splashy exercise could help scientists identify ways to inject fluids such as vaccines through skin without using needles.
Magnets could offer better control of prosthetic limbs
System uses tiny magnetic beads to rapidly measure the position of muscles and relay that information to a bionic prosthesis.
For people with amputation who have prosthetic limbs, one of the greatest challenges is controlling the prosthesis so that it moves the same way a natural limb would. Most prosthetic limbs are controlled using electromyography, a way of recording electrical activity from the muscles, but this approach provides only limited control of the prosthesis.
Social interaction can help fight depression in people with dementia
Social and group activities can help fight depression in people with dementia, new research has found.
Researchers from the University of Sheffield and Brighton and Sussex Medical School, have analysed the use of cognitive stimulation as an effective treatment for people with dementia.
Common weight-loss drug successfully targets fat that can endanger heart health
Researchers at UT Southwestern announced successful results of a clinical trial for a commonly prescribed weight-loss drug called liraglutide. In adults who are overweight or have obesity combined with high cardiovascular risk, once-daily liraglutide combined with lifestyle interventions significantly lowered two types of fat that have been associated with risk to heart health: visceral fat and ectopic fat.
Wearable Brain-Machine Interface Turns Intentions into Actions
A new wearable brain-machine interface (BMI) system could improve the quality of life for people with motor dysfunction or paralysis, even those struggling with locked-in syndrome – when a person is fully conscious but unable to move or communicate.
A peek inside a flying bat’s brain uncovers clues to mammalian navigation
When driving up to a busy intersection, you probably pay more attention to where you will be in the near future than where you are at that moment. After all, knowing when you will arrive at the intersection — and whether you need to stop or slow down to avoid a collision with a passing car, pedestrian or cyclist — is usually much more important than knowing your current location.
FUNGI THAT LIVE IN THE GUT INFLUENCE HEALTH AND DISEASE
Bacteria’s role in gut health has received a lot of attention in recent years. But new research led by scientists at University of Utah Health shows that fungi—another microorganism that lives within us—may be equally important in health and disease.
Common Diabetes Drug Shows Promise as Treatment for COVID-19 Lung Inflammation
Metformin is a widely prescribed blood sugar-lowering drug. It is often used as an early therapy (in combination with diet and lifestyle changes) for type 2 diabetes, which afflicts more than 34 million Americans.
SARS-CoV-2 Detectable — Though Likely Not Transmissible — on Hospital Surfaces
Watching what was happening around the world in early 2020, University of California San Diego School of Medicine researchers knew their region would likely soon be hit with a wave of patients with COVID-19, the infection caused by the coronavirus SARS-CoV-2. They wondered how the virus persists on surfaces, particularly in hospitals, and they knew they had only a small window of time to get started if they wanted to capture a snapshot of the “before” situation — before patients with the infection were admitted.
