Lack of uniformity is possibly the biggest challenge in today’s technology of memristor devices as it gives rise to problems like inconsistency, stochastic variability, and instability of the memory state. A uniform switching mechanism in memristors is something researchers have been looking at in the last several decades.

Now, an international team, led by the scientists from the National University of Singapore (NUS), has developed a solution to address this long-standing problem in the field of organic and molecular electronics.

Professor T. Venkatesan, who led this project, said, “We are working on an organic material system that is possibly one of the most efficient platforms for realizing artificial intelligence and brain-inspired computing...

Lakes on Saturn’s moon Titan, composed of methane, ethane, and nitrogen rather than water, experience density driven stratification, forming layers similar to lakes on Earth. However, whereas lakes on Earth stratify in response to temperature, Titan’s lakes stratify solely due to the strange chemical interactions between its surface liquids and atmosphere, says a paper by Planetary Science Institute Research Scientist Jordan Steckloff.

Stratification occurs when different parts of a lake have different densities, with the less dense layer floating atop the denser layer...

A type of anti-bacterial T cells, so-called MAIT cells, are strongly activated in people with moderate to severe COVID-19 disease, according to a study by researchers at Karolinska Institutet in Sweden that is published in the journal...

It uses terahertz radiation to power a miniscule copper accelerator structure...
