Researchers develop new model to observe self-optimization phenomenon in neuronal networks

Researchers at the Cyber-Physical Systems Group at the USC Viterbi School of Engineering, in conjunction with the University of Illinois at Urbana-Champaign, have developed a new model of how information deep in the brain could flow from one network to another and how these neuronal network clusters self-optimize over time.

Their work, chronicled in the paper “Network Science Characteristics of Brain-Derived Neuronal Cultures Deciphered From Quantitative Phase Imaging Data,” is believed to be the first study to observe this self-optimization phenomenon in in vitro neuronal networks, and counters existing models. Their findings can open new research directions for biologically inspired artificial intelligence, detection of brain cancer and diagnosis and may contribute to or inspire new Parkinson’s treatment strategies.

The team examined the structure and evolution of neuronal networks in the brains of mice and rats in order to identify the connectivity patterns.

USC researchers build model showing how many coronavirus infections masks prevent | Health

University of South Carolina researchers have developed a model of the coronavirus pandemic showing that masks have stemmed the spread of disease and prevented tens of thousands of infections in places that have adopted them widely.

The team’s aim is to put hard numbers on a refrain that public health experts have repeated for months: that masks make a difference and could bring the virus to heel. The lead researcher says he wanted to give decision-makers a clear view of how big that difference is.

That’s particularly significant in South Carolina, which doesn’t have a statewide mask requirement. Instead, questions about whether to wear a mask are far more localized here. It’s up to local governments to decide whether to require them, and for the millions of people here who aren’t bound by mandates, wearing a mask is an individual decision.

The USC model, developed by the university’s Automated Intelligence

Researchers create p16-Cre ERT2 -tdTomato mouse model to characterize in vivo senescent cells

Cell senescence is a state of permanent cell cycle arrest that was initially defined for cells grown in cell culture. It plays a key role in age-associated organ dysfunction and age-related diseases such as cancer, but the in vivo pathogenesis is largely unclear.

A research team led by Professor Makoto Nakanishi of the Institute of Medical Science, the University of Tokyo, generated a p16-Cre ERT2 -tdTomato mouse model to characterize in vivo p16 high cells at the single-cell level.

They found tdTomato-positive p16 high cells detectable in all organs, which were enriched with age. They also found that these cells failed to proliferate and had half-lives ranging from 2.6 to 4.2 months, depending on the tissue examined.

Single-cell transcriptomics in the liver and kidneys revealed that p16 high cells were present in various cell types, though most dominant in hepatic endothelium and

Researchers reveal the perfect ‘flirty’ face for women: study

Sometimes, all it takes is a look.

For some single people, it can be hard to tell when someone is actually flirting with you. Fortunately for them, new research suggests that there may be a specific facial expression that women use when they’re flirting.

A study published in the Journal of Sex Research says that there are certain facial expressions that signify interest in a potential partner.
