Embryonic stem cells and other pluripotent cells divide rapidly and have the capacity to become nearly any cell type in the body. Scientists have long sought to understand the signals that prompt stem cells to switch off pluripotency and adopt their final functional state.

In a study published in the Proceedings of the National Academy of Sciences, researchers report that they have identified a key regulator of this process. They discovered that a molecule known as BEND3 shuts down expression of hundreds of genes associated with differentiation, maintaining the cell’s stem cell-like status. Only when BEND3 is downregulated can adopt their final form and function. Once they differentiate, they usually stop actively proliferating.

The findings are relevant to understanding normal development and also may be useful in , said University of Illinois Urbana-Champaign cell and developmental biology professor and department head Supriya Prasanth, who led the research.

Scientists created a new type of Computer Chip which has the ability to constantly rewire itself just like the human brain and is thus able to more efficiently adapt to new processes. This is a new type of neuromorphic computing and holds great promise for future and better Artificial Intelligence models which more closely resemble how humans behave. You will not believe this unbelievable AI Robot Computer Chip!

A large new study shows people who contracted #COVID19 faced substantially higher risks of neuropsychiatric ailments 1 year later, including brain fog, depression, and substance use disorders.

Dozens of papers have examined the lingering mental health effects of COVID-19, but many have measured conditions such as depression and brain fog only a few months after infection. Now, a giant new study shows people who contracted COVID-19 faced substantially higher risks of neuropsychiatric ailments 1 year later, including brain fog, depression, and substance use disorders. The report, based on millions of people who used the U.S. Department of Veterans Affairs (VA) health system early in the pandemic, is published today in.

“Most of us experienced some sort of mental distress during the pandemic, but this shows that people with COVID-19 had a much higher risk of mental health disorders than their contemporaries,” says senior author Ziyad Al-Aly, a clinical epidemiologist at Washington University in St. Louis and chief of research at the VA St. Louis Health Care system. “It’s a wake-up call.”

Other scientists praise the study’s size. “The scale of … this study sets [it] apart … as well as the quality of the statistical methods used,” says Alex Charney, a neuroscientist and psychiatrist at the Mount Sinai Health System.

Bipartisan hostility toward China means US lawmakers are unlikely to cite Chinese regulations as inspiration. But Beijing’s manoeuvres could perhaps have a subtle effect. In the UK, some lawmakers have called for online companies to shield young people from harmful content in an approach that some have likened to China’s proposals. “These ideas could ripple out,” says Matt Sheehan, a fellow at the Carnegie Endowment for International Peace who researches China’s AI ecosystem. “What’s interesting in China is that they’re going to be able to run experiments at a very large scale on what it actually means to implement these ideas.”

Sweeping rules will cover algorithms that set prices, control search results, recommend videos, and filter content.

Whoop Energy and XCel Power have ceased trading – affecting around 550 customers.

Consumers from both energy firms will be designated a new supplier by market regulator Ofgem – through its supplier of last resort process.

Whoop Energy (Whoop) provides gas and electricity to 262 customers, including 50 households (domestic consumers).
