Researchers at the University of Missouri have created a low-cost, portable device that can apply non-invasive bioluminescent imaging technology to many uses in animals, humans.

A biochemical reaction between an enzyme called luciferase and oxygen causes fireflies to glow and is considered one of the most well-known examples of bioluminescence in nature...

Researchers have confirmed the existence of magnetic plasma waves, known as Alfvén waves, in the Sun’s photosphere. The study, published in Nature Astronomy, provides new insights into these fascinating waves that were first discovered by the Nobel Prize winning scientist Hannes Alfvén in 1947.

The vast potential of these waves resides in their ability to transport energy and information over very large distances due to their purely magnetic nature. The direct discovery of these waves in the solar photosphere, the lowest layer of the solar atmosphere, is the first step towards exploiting the properties of these magnetic waves.

The ability for Alfvén waves to carry energy is also of interest for solar and plasma-astrophysics as it could help explain the extreme heating of the s...

MRSA skin infections are often treated with intravenous injection of antibiotics, which can cause significant side effects and promote the development of resistant bacterial strains. To solve these problems, researchers at Karolinska Institutet in Sweden are developing a microneedle patch that delivers antibiotics directly into the affected skin area. New results published in Advanced Materials Technologies show that the microneedle patch effectively reduces MRSA bacteria in the skin.

MRSA (methicillin resistant Staphylococcus aureus) skin infections are potentially lethal, especially in patients with compromised immune systems...

As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, Penn State researchers have designed a way to make the encrypted keys harder to crack.

Led by Saptarshi Das, assistant professor of engineering science and mechanics, the researchers used graphene — a layer of carbon one atom thick — to develop a no...
