Traditional Ghanaian medicines show promise against tropical diseases

The discovery of new drugs is vital to achieving the eradication of neglected tropical diseases (NTDs) in Africa and around the world. Now, researchers have identified traditional Ghanaian medicines which work in the lab against schistosomiasis, onchocerciasis and lymphatic filariasis, three diseases endemic to Ghana.

Stretching diamond for next-generation microelectronics

Diamond is the hardest material in nature. It also has great potential as an excellent electronic material. A research team has demonstrated for the first time the large, uniform tensile elastic straining of microfabricated diamond arrays through the nanomechanical approach. Their findings have shown the potential of strained diamonds as prime candidates for advanced functional devices in...

Spontaneous robot dances highlight a new kind of order in active matter

Researchers have proposed a new principle by which active matter systems can spontaneously order, without need for higher level instructions or even programmed interaction among the agents. And they have demonstrated this principle in a variety of systems, including groups of periodically shape-changing robots called 'smarticles.'

Social media safety messages: Pictures should match the words

When using social media to nudge people toward safe and healthy behaviors, it's critical to make sure the words match the pictures, according to a new study. After looking at social media posts, parents of young children were better able to recall safety messages such as how to put a baby safely to sleep when the images in the posts aligned with the messages in the text.

Blood vessel cells implicated in chronic inflammation of obesity

When fat cells in the body are stuffed with excess fat, the surrounding tissue becomes inflamed. That chronic, low-level inflammation is one of the driving factors behind many of the diseases associated with obesity. Now, scientists have discovered a type of cell responsible, at least in mice, for triggering this inflammation in fat tissue. Their findings could eventually lead to new ways to treat...

New research may explain severe virus attacks on the lungs

In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers describe how different kinds of immune cells, called macrophages, develop in the lungs and which of them may be behind severe lung diseases. The study may contribute to future treatments for COVID-19, among other diseases.

Potential new RX strategy for stroke

new research reports that a combination of a new drug and selected DHA derivatives is more effective in protecting brain cells and increasing recovery after stroke than a single drug.

More effective training model for robots

Multi-domain operations, the Army's future operating concept, requires autonomous agents with learning components to operate alongside the warfighter. New research reduces the unpredictability of current training reinforcement learning policies so that they are more practically applicable to physical systems, especially ground robots.

General anesthesia and normal sleep affect brain in an amazingly similar way as consciousness fades

What happens in the brain when our conscious awareness fades during general anesthesia and normal sleep? Scientists studied this question with novel experimental designs and functional brain imaging. They succeeded in separating the specific changes related to consciousness from the more widespread overall effects, and discovered that the effects of anesthesia and sleep on brain activity were...

Stopping RAS inhibitors tied to worse outcomes in patients with chronic kidney disease

Small studies have suggested that a group of medications called RAS inhibitors may be harmful in persons with advanced chronic kidney disease, and physicians therefore often stop the treatment in such patients. Researchers now show that although stopping the treatment is linked to a lower risk of requiring dialysis, it is also linked to a higher risk of cardiovascular events and death.
