Is virtual reality the future of live music? — BBC News
Virtual reality, the future of concerts.
With Covid-19 restrictions stopping live performances some musicians have turned to virtual reality to create new live experiences.
Artists perform in front of a green screen and concerts are broadcast to an audience wearing VR headsets.
So will this be the future of music?

Israeli researchers say llama nanobodies could help stop COVID
I think I posted about the work in Texas, but here is more work.
Israeli and American researchers have discovered a nanobody cocktail that could neutralize coronavirus, including the Delta mutation.
Nanobodies are single domain antibodies derived from llamas — or other members of the camel family.
The discovery of the cocktail and their effectiveness in combating coronavirus was published in the peer-reviewed journal Nature Communications.
“If we can produce an innovative drug through the cocktail, it will be a life-saving treatment — if given early in the disease,” according to Hebrew University School of Engineering and Computer Science Dr. Dina Schneidman-Duhovy, who helped lead the study with University of Pittsburgh researcher Dr. Yi Shi.
A team of Israeli and American researchers have found a combination of antibodies derived from llamas that may be effective in treating the coronavirus.
Brain Cholesterol Regulates Alzheimer’s Plaques
“We showed that cholesterol is acting essentially as a signal in neurons that determines how much Aβ gets made—and thus it should be unsurprising that apoE, which carries the cholesterol to neurons, influences Alzheimer’s risk,” says study co-senior author Scott Hansen, PhD, an associate professor in the Department of Molecular Medicine at Scripps Research, Florida.
Summary: A new advanced imaging technique shows how cholesterol regulates the production of Alzheimer’s associated amyloid beta proteins in astrocytes.

A team co-led by scientists at Scripps Research has used advanced imaging methods to reveal how the production of the Alzheimer’s-associated protein amyloid beta (Aβ) in the brain is tightly regulated by cholesterol.
Appearing on line Thursday ahead of print in the Aug. 17 issue of the Proceedings of the National Academy of Sciences (PNAS), the scientists’ work advances understanding of how Alzheimer’s disease develops and underscores the long-underappreciated role of brain cholesterol.
University of Utah researchers may have found a way to fix a broken heart
These researchers recently published a study on VDAC2, a protein that helps regulate calcium signaling within heart cells. Blockage of the signals causes severe impairment of heart cell contraction, making it harder for the organ to push blood through the body.
Taking away this protein made heart function sharply decline in laboratory mice, eventually leading to their death, while reintroduction of VDAC2 reversed many of the effects of heart failure. An experimental drug called efsevin was able to produce similar effects in other mice with heart failure.
With the epidemic of heart failure exacerbating the pandemic of COVID-19, the discovery by University of Utah researchers in Salt Lake City of a protein in heart cells brings the potential for a method to improve heart function in patients.
