Almost as contagious as measles: Coronavirus spins out worrisome new mutations

Posted by in categories: biotech/medical, energy, health

The relentless evolution of the coronavirus, which has spawned new variants to fuel fresh surges of disease every four to six months, could in the not-distant future propel the virus to overtake measles as the most contagious of all known infections.

Increasing infectiousness does not necessarily make the virus deadlier, but it could make it harder to control, and leave communities vulnerable to the repeated waves of illness that have defined the pandemic.

The variants now dominating around the world may be five to 10 times more infectious than the original virus that sparked the pandemic in China in late 2019, health experts believe. Lately each variant has outpaced its parent — omicron, with its massive evolutionary jump, was about three times more infectious than delta. Its subvariants — BA.2 and BA.2.12.1, which are driving the latest surge in the Bay Area — are each more infectious still, by 20% to 30%.

Professor Sean Carroll explains the theories of Presentism and Eternalism

Posted by in categories: mathematics, physics

It’s said that the clock is always ticking, but there’s a chance that it isn’t. The theory of “presentism” states that the current moment is the only thing that’s real, while “eternalism” is the belief that all existence in time is equally real. Find out if the future is really out there and predictable—just don’t tell us who wins the big game next year.

This video is episode two from the series “Mysteries of Modern Physics: Time”, Presented by Sean Carroll.

Spin keeps electrons in line in iron-based superconductor

Posted by in categories: materials, quantum physics

Researchers from PSI’s Spectroscopy of Quantum Materials group together with scientists from Beijing Normal University have solved a puzzle at the forefront of research into iron-based superconductors: the origin of FeSe’s electronic nematicity. Using Resonant inelastic X-ray scattering (RIXS) at the Swiss Light Source (SLS), they discovered that, surprisingly, this electronic phenomenon is primarily spin driven.

Electronic nematicity is believed to be an important ingredient in high-temperature superconductivity, but whether it helps or hinders it is still unknown.

Their findings are published in Nature Physics (“Spin-excitation anisotropy in the nematic state of detwinned FeSe”).

Stimulating Brain Circuits Promotes Neuron Growth in Adulthood, Improving Cognition and Mood

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

Summary: Researchers used optogenetics techniques to stimulate specific brain areas to increase neurogenesis and the production of neural stem cells to improve memory, cognition, and emotional processing in animal models.

Source: UNC Health Care.

We humans lose mental acuity, an unfortunate side effect of aging. And for individuals with neurodegenerative conditions such as Alzheimer’s and Parkinson’s, the loss of cognitive function often accompanied by mood disorders such as anxiety is a harrowing experience. One way to push back against cognitive decline and anxiety would be to spur the creation of new neurons.

Uploading Memories: Elon Musk’s Brain Chip (Neuralink Future Technology)

Posted by in categories: biotech/medical, education, Elon Musk, robotics/AI

The long term goal for Elon Musk and brain to computer interfaces (brain chips) is to merge our minds with artificial intelligence. While the short term goal for Neuralink and other companies is to help people with medical issues.

This short documentary video takes a look at connecting our brains to computers, and how this works is explained. We also take a look at the downsides of people connecting their brains, the technology being used today, and Elon Musk’s thoughts.
