Physics tool helps track cancer cell diversity

Cancer cells are a wily adversary. One reason the disease outfoxes many potential treatments is because of the diversity of the cancer cell population. Researchers have found this population difficult to characterize and quantify. A Cornell-led team took a novel,...

Brain cells protect muscles from wasting away

While many of us worry about proteins aggregating in our brains as we age and potentially causing Alzheimer's disease or other types of neurodegeneration, we may not realize that some of the same proteins are aggregating in our muscles, setting...

Drug cocktail holds promise for spinal injuries

The early-stage research in rats, by a group of scientists led by Imperial College London, revealed two existing medications can boost the body's own repair machinery, by triggering the release of stem cells from the bone marrow. The scientists published...

Surgeons successfully treat brain aneurysms using a robot

Using a robot to treat brain aneurysms is feasible and could allow for improved precision when placing stents, coils and other devices, according to late breaking science presented today at the American Stroke Association's International Stroke Conference 2020 . The...

Changing what heart cells eat could help them regenerate

Switching what the powerhouses of heart cells consume for energy could help the heart regenerate when cells die, a new study led by UT Southwestern researchers suggests. The finding, published in the Feb. 20, 2020, Nature Metabolism, could open whole...

Neighborhood features and one’s genetic makeup interact to affect cognitive function

The neighborhood environment may positively or negatively influence one's ability to maintain cognitive function with age. Since older adults spend less time outside, the neighborhood environment increases in importance with age. Studies suggest physical aspects of the neighborhood such as...

People who eat a big breakfast may burn twice as many calories

Eating a big breakfast rather than a large dinner may prevent obesity and high blood sugar, according to new research published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism. Our body expends energy when we digest food for...

What birdsong tells us about brain cells and learning

Most scientists who study the brain believe that memories are stored through networks of synapses, or connections that form between neurons. Learning takes place as neurons form new connections and strengthen or weaken existing ones, giving the brain its so-called...

New strategies for helping children process negative emotions

A recent study of indigenous people in southern Chile challenges some Western assumptions about children's emotional capabilities and highlights the potential value of spending time outdoors to help children regulate their emotions. "I think many people, particularly in Western cultures,...

Pill-sized ‘heater’ could increase accessibility in diagnosing infectious disease

Researchers at the University of Toronto Engineering have developed a tiny "heater" -- about the size of a pill -- that could allow resource-limited regions around the world to test for infectious diseases without the need for specialized training or...
