Using a new strategy, researchers were able to reduce the challenging MRSA infection in the wounds of diabetic mice by 94%. They were able to completely sterilize the wounds in several of the mice, and the rest had significantly reduced bacterial burden.

Chronic wounds are open sores or injured tissue that fail to heal properly. These types of wounds are notoriously challenging to treat because of bacterial infections like Staphylococcus aureus, or S. aureus. Additionally, bacterial infections that are highly resistant to antibiotics, such as methicillin-resistant S...

New technique paves the way for easy oxidation of historically ‘stubborn’ metals. A University of Minnesota Twin Cities-led team has developed a first-of-its-kind, breakthrough method that makes it easier to create high-quality metal oxide thin films out of “stubborn” metals that have historically been difficult to synthesize in an atomically precise manner...

Exercise seems to Protect against Major Brain Hemorrhage

Regular physical activity and exercise may reduce bleeding in individuals with intracerebral hemorrhage, a University of Gothenburg study shows. The researchers emphasize the importance of physical activity to protect the brain.

The study, published in the journal Stroke and Vascular Neurology, analyzed data on 686 people treated for intracerebral hemorrhage at Sahlgrenska University Hospital in Gothenburg during the years 2014 to 2019.

The results are based on a retrospective analysis. Causal connections cannot be identified, but the findings are nonetheless clear: Those who reported regular physical activity had smaller hemorrhages than those who reported being inactive.

Physically active was defined as engaging in at least light physical activity, such a...

Radio Signal Reveals Supernova Origin

In the latest issue of the journal Nature, astronomers from Stockholm University reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion.

Supernovae of Type Ia are important for astronomers since they are used to measure the expansion of the Universe. However, the origin of these explosions has remained an open question...
