Do some diabetes drugs reduce the risk of Alzheimer’s?

People taking certain drugs to lower blood sugar for type 2 diabetes had less amyloid in the brain, a biomarker of Alzheimer's disease, when compared to both people with type 2 diabetes not taking the drugs and people without diabetes. The new study also found people taking these drugs, called dipeptidyl peptidase-4 inhibitors, showed slower cognitive decline than people in the other two groups.

Monoclonal antibody may prevent malaria

One dose of a new monoclonal antibody prevented malaria for up to nine months in people who were exposed to the malaria parasite. The small, carefully monitored clinical trial is the first to demonstrate that a monoclonal antibody can prevent malaria in people.

People with stroke who walk 30 minutes per day may have 54% lower risk of early death

A new study shows that people who walk or garden at least three to four hours per week, or bike at least two to three hours per week, or the equivalent after having a stroke may have a 54% lower risk of early death from any cause. The study found the most benefit for younger stroke survivors. When people under the age of 75 exercised at least that amount, their risk of early death was reduced by...

Study shows differences in rapidly processing sensory feedback among people with autism spectrum disorder

In an effort to better characterize -- and quantify -- sensorimotor abilities and their impact on the development of people with ASD, scientists have published research that compared the fine motor control and eye movements of more than 200 people from age 5 to 29. The study showed key differences in the ways that individuals with ASD processed or reacted to stimuli compared to those who were more...

Protecting Earth from space storms

A major space weather event could have a catastrophic impact on Earth, disabling communications and electrical systems. Researchers are using the Frontera supercomputer to develop new geomagnetic forecasting methods and improve the Geospace Model used by NOAA for operational purposes. They hope to increase the lead time for space weather events from 30 minutes to 1-3 days, localize space weather...

Treating the ‘root’ cause of baldness with a dissolvable microneedle patch

Although some people say that baldness is the 'new sexy,' for those losing their hair, it can be distressing. An array of over-the-counter remedies are available, but most of them don't focus on the primary causes: oxidative stress and insufficient circulation. Now, researchers have designed a preliminary microneedle patch containing cerium nanoparticles to combat both problems, regrowing hair in...

A brief history of the cabbage butterfly’s evolving tastes

The cabbage butterfly, voracious as a caterpillar, is every gardener's menace. Turns out, these lovely white or sulfur yellow butterflies started trying to take over the planet long ago. Biologists used statistical methods to trace the path of Pieridae family butterflies as they diversified and their plant hosts fought back, over and over again. The study also finds that butterflies often regain...

Scientists develop chain mail fabric that can stiffen on demand

Scientists have developed a new type of 'chain mail' fabric that is flexible like cloth but can stiffen on demand. The lightweight fabric is 3D-printed from nylon plastic polymers and comprises hollow octahedrons (a shape with eight equal triangular faces) that interlock with each other. When encased in a plastic envelope and vacuum-packed, it becomes 25 times more rigid and can hold up over 50...

Gen Z willing to rent clothes to reduce waste

Gen Z adults are interested in using apparel rental services to reduce overconsumption, according to a new study. Apparel rental, also known as collaborative apparel consumption, extends the life of an article of clothing because people don't throw it away after wearing it a few times.
