A COVID-19 vaccine that can be produced locally in low-income and middle-income countries is yielding promising results in early clinical trials, researchers say. Other researchers believe that once the body has been “primed” by mRNA vaccines to recognize and attack the coronavirus, a booster containing purified versions of virus’ spike protein that could be given intranasally would have many advantages.

A study by The National Institutes for Quantum Science and Technology in Japan found that a supplement with seven specific amino acids called Amino LP7 appeared to slow brain degeneration and dementia development in mice.

A research study in mice by investigators at the University of Rochester Medical Center suggests it would be possible to repair the brain cell damage caused by multiple sclerosis (MS).

Researchers at Flinders University in Australia – working with mice – removed a single gene known as RCAN1 and then fed them a variety of diets, including a high-fat diet. The mice did not gain weight, even after dramatically overeating high-fat foods over several weeks.

AIDS researchers in Hong Kong say new research – tested on mice – indicates a functional cure for HIV, eventually leading to a new antibody that could be used for prevention and treatment.
