Scientists are working on new materials to create neuromorphic computers, with a design based on the human brain. A crucial component is a memristive device, the resistance of which depends on the history of the device — just like the response of our neurons depends on previous input. Materials scientists from the University of Groningen analysed the behaviour of strontium titanium oxide, a platform material for memristor research and used the 2D material graphene to probe it. On 11 November 2020, the results were published in the journal ACS Applied Materials and Interfaces.

Scientists have uncovered a method of combining natural organic compounds which can create anticancer drugs with minimal side effects. They have discovered a method of synthesizing organic compounds that are four times more fatal to cancer cells and leave non-cancerous cells unharmed.

In the past decades, cancer has surpassed many other diseases to become the current second leading cause of death globally, with one in six people dying from it. This concerning position has given it a unique and ubiquitous position in global culture, so much so that finding a cure for cancer is considered one of the most noble things any person can do. Sadly, humanity hasn’t arrived at this cure yet; tons of research is being conducted to explore every angle of cancer, trying to find a weakness.

Restricting meals to early in the day did not affect weight among overweight adults with prediabetes or diabetes, according to preliminary research to be presented at the American Heart Association’s Scientific Sessions 2020. The meeting will be held virtually, Friday, November 13 — Tuesday, November 17, 2020.

“We have wondered for a long time if when one eats during the day affects the way the body uses and stores energy,” said study author Nisa M. Maruthur, M.D., M.H.S., associate professor of medicine, epidemiology and nursing at Johns Hopkins University in Baltimore. “Most prior studies have not controlled the number of calories, so it wasn’t clear if people who ate earlier just ate fewer calories. In this study, the only thing we changed was the time of day of eating.”

Pearls have long been favored as objects of beauty. Now, Purdue University innovators are using the gem to provide potential new opportunities for spectral information processing that can be applied to spectroscopy in biomedical and military applications.

The Purdue team demonstrated light transport-assisted information processing by creating a pearl spectrometer.

Spectrometers probe interactions of matter and light as a function of the electromagnetic spectrum and are commonly used in biomedical and military applications. For example, they have been used for diagnostics of various types of cancer and for military gas sensing.
