Amyloid plaques found in the retinas of eyes may be an indicator of similar plaques in the brain, a hallmark of Alzheimer’s disease, and may provide a more visible biomarker for detecting disease risk.

In a finding that could help pave the way toward cleaner fuels and a more sustainable chemical industry, researchers have used machine learning to predict how the compositions of metal alloys and metal oxides affect their electronic structures.

A nationwide US study has shown that the rate of opioid-related cardiac arrests has steeply risen and is now on par with the rate of cardiac arrest from other causes. Opioid use disorder, which includes dependence and addiction, affects more than two m…

Magnesium rechargeable batteries show immense promise for a greener future because of their energy density, safety, and cost. But the lack of high-performance cathode materials has impeded their development. Now, a research team has developed liquid-su…

Researchers have developed a mathematical model that can predict the optimum exercise regime for building muscle.

Sjögren’s syndrome is an autoimmune disease that attacks the tear duct and salivary glands, leading to patients suffering unbearable dry eyes and mouth. To date, treatment options have been limited. But this may change thanks to a recently developed mo…

The miniaturization of microelectronic sensor technology, microelectronic robots or intravascular implants is progressing rapidly. However, it also poses major challenges for research. One of the biggest is the development of tiny but efficient energy …

A study found that as meltwater lakes on the surface of Greenland’s ice sheet rapidly drain, they create water blisters between the ice and the bedrock that scientists could use to understand the hydrological network below Greenland’s thick inland ice …

Diclofenac and other NSAIDs may limit the passage of narcolepsy medication and illicit party drug GHB to the brain, decreasing the potential for fatal overdose, researchers find.

Research suggests that introducing new airline routes reduces the discard rate of donated kidneys and increases the number of kidneys sent to transplant centers across the U.S.

Researchers have developed a new type of laminate that changes color as soon as the material is deformed. This way, the materials researchers can kill two birds with one stone: a lightweight composite material that inspects itself.

Experts have assessed the risks and potential benefits associated with deploying autonomous vehicles (AVs) on U.S. roads and predicts that the benefits will substantially outweigh potential harms — but only if the AVs are well regulated.

Researchers show that pecans can dramatically improve a person’s cholesterol levels.

Farmers using no-till production — in which soil never or rarely is plowed or disturbed — can reduce herbicide use and still maintain crop yields by implementing integrated weed-management methods, according to a new study.

A preclinical study has analyzed the interactions of the lipid mediator sphingosine-1-phosphate (S1P) in the spleen and heart during the transition from acute to chronic heart failure. Using a mouse model of heart failure, the researchers discovered ne…

Researchers find a way to better pinpoint the ‘golden window’ when a womb is ready for pregnancy, in a discovery that could help boost IVF success rates.

A six-month exercise program helps maintain normal heart rhythm and reduces the severity of symptoms in patients with atrial fibrillation, according to new research.

The number of spectacled bears in Peru might be larger than suspected, a new study suggests. A team of researchers studied the population of the endangered species in Northern Peru. By identifying individuals through facial patterns, they were able to …

Mosquitoes spread viruses that cause potentially deadly diseases such as Zika, dengue fever and yellow fever. New research uses gene editing to render certain male mosquitoes infertile and slow the spread of these diseases.

If you’ve ever suffered from a sore jaw that popped or clicked when you chewed gum or crunched hard foods, you may be able to blame it on your extinct ancestors. That’s according to a recent study of the chewing mechanics of an ancient human relative c…
