A 50-year-old science problem has been solved and could allow for dramatic changes in the fight against diseases, researchers say.

For years, scientists have been struggling with the problem of “protein folding” – mapping the three-dimensional shapes of the proteins that are responsible for diseases from cancer to Covid-19.

Researchers at the University of Basel have discovered a molecular mechanism that plays a central role in intact long-term memory. This mechanism is also involved in physiological memory loss in old age.

Many life forms, from worms to humans, have differentiated memory functions, such as short-term and long-term memory. Interestingly, at the cell and molecule level, many of these functions are nearly identical from life form to life form. Detecting the molecules involved in memory processes is of great importance to both basic and clinical research, since it can point the way to the development of drugs for memory disorders.

By studying roundworms (Caenorhabditis elegans), scientists at the Transfaculty Research Platform for Molecular and Cognitive Neurosciences (MCN) at the University of Basel have now discovered a molecular mechanism of long-term memory that is also involved in memory loss in old age. They report on their findings in the journal Current Biology.

Kewl… ~~~ “Led by Associate Professor Alfredo Franco-Obregón from the NUS Institute for Health Innovation and Technology (iHealthtech), the team found that a protein known as TRPC1 responds to weak oscillating magnetic fields. Such a response is normally activated when the body exercises. This responsiveness to magnets could be used to stimulate muscle recovery, which could improve the life quality for patients with impaired mobility, in an increasingly aging society.”

As people age, they progressively lose muscle mass and strength, and this can lead to frailty and other age-related diseases. As the causes for the decline remain largely unknown, promoting muscle health is an area of great research interest. A recent study led by the researchers from NUS has shown how a molecule found in muscles responds to weak magnetic fields to promote muscle health.

LONDON — Alphabet-owned DeepMind has developed a piece of artificial intelligence software that can accurately predict the structure that proteins will fold into in a matter of days, solving a 50-year-old “grand challenge” that could pave the way for better understanding of diseases and drug discovery.

Every living cell has thousands of different proteins inside that keep it alive and well. Predicting the shape that a protein will fold into is important because it determines their function and nearly all diseases, including cancer and dementia, are related to how proteins function.

“Proteins are the most beautiful, gorgeous structures and the ability to predict exactly how they fold up is really very, very challenging and has occupied many people over many years,” Professor Dame Janet Thornton from the European Bioinformatics Institute told journalists on a call.

Researchers at DeepMind say they have solved “the protein folding problem,” a task that has bedeviled scientists for more than 50 years.

If I was a billionaire, I’d want to keep the profits flowing…

This chart shows the change in wealth of U.S. billionaires since the start of the pandemic.

Video. Well, at least the planet/environment benefits somewhat from what’s currently happening.

Maybe we can continue the good while overcoming the bad?

Pandemic restrictions reduced global nitrogen dioxide concentrations by nearly 20%, NASA finds.

The Army Research Office has pledged $6.25 million towards developing mindreading technology for use on the battlefield.

A Singaporean mom who beat COVID-19 while pregnant has given birth to a baby with antibodies against the virus, according to a report.

Celine Ng-Chang, 31, gave birth this month to the baby boy, who tested negative for the virus but did have the antibodies, the Straits Times reported.

“My doctor suspects I have transferred my COVID-19 antibodies to him during my pregnancy,” she told the newspaper.
