A study spearheaded by Oregon State University has shown why certain polyunsaturated fatty acids work to combat a dangerous liver condition, opening a new avenue of drug research for a disease that currently has no FDA-approved medications.

Scientists led by Oregon State’s Natalia Shulzhenko, Andrey Morgun and Donald Jump used a technique known as multi-omic network analysis to identify the mechanism through which dietary omega 3 supplements alleviated nonalcoholic steatohepatitis, usually abbreviated to NASH.

The mechanism involves betacellulin, a protein growth factor that plays multiple positive roles in the body but also contributes to liver fibrosis, or scarring, and the progression to cirrhosis and liver cancer.

“We only succeeded in ...

Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.

The discovery could shed light on the mysteries behind the magnetic fields of the planets of our solar system, and even on whether distant worlds might support life.

The team of scientists, supported by the Science and Technology Facilities Council (STFC), have obtained the first measurements of the infrared (IR) aurora at Uranus since investigations began in 1992. While the ultraviolet (UV) aurorae of Uranus has been observed since 1986, no confirmation of the IR aurora had been observed until now...

The search is on for better semiconductors. Writing in Science, a team of chemists at Columbia University led by Jack Tulyag, a PhD student working with chemistry professor Milan Delor, describes the fastest and most efficient semiconductor yet: a superatomic material called Re6Se8Cl2.

Semiconductors — most notably, silicon — underpin the computers, cellphones, and other electronic devices that power our daily lives, including the device on which you are reading this article. As ubiquitous as semiconductors have become, they come with limitations...

Broccoli sprouts have been discovered to contain 7X more polysulfides than mature broccoli. A research team from Osaka Metropolitan University has found that polysulfides are abundant in broccoli sprouts. They found that the amount of polysulfides increased dramatically during growth, by an approximately 20-fold in seeds by the fifth day of germination. Furthermore, a comprehensive analysis of the polysulfides detected a number of polysulfide candidates whose structures have not yet been determined. The identification of these unknown polysulfides and detailed analysis of their pharmacological activities are expected to enable the development of new preventive and therapeutic strategies and medicines for cancer, neurodegenerative diseases, stroke, inflammation, and other diseases.
