— by Zia Sherrell, MPHResearchers have taken the first step toward developing a novel type of vaccine regimen that could protect people against HIV.The virus, which progressively weakens the immune system, affects worldwide.Highly effective antiviral treatments for HIV are available, but those living with the virus must take them for the rest of their life, and the of infection remain challenging.In addition, access to prevention and treatment services is limited in some parts of the world.The estimates that, as a result, there were 1.7 million new infections with HIV in 2019, and 690,000...…— by Zia Sherrell, MPHResearchers have taken the first step toward developing a novel type of vaccine regimen that could protect people against HIV.The virus, which progressively weakens the immune system, affects worldwide.Highly effective antiviral treatments for HIV are available, but those living with the virus must take them for the rest of their life, and the of infection remain challenging.In addition, access to prevention and treatment services is limited in some parts of the world.The estimates that, as a result, there were 1.7 million new infections with HIV in 2019, and 690,000...WW…

— by Hannah Flynn, MSAll data and statistics are based on publicly available data at the time of publication. Some information may be out of date. A key factor that will determine how soon life can return to normal after the pandemic is how easily people can reacquire SARS-CoV-2, which is the virus that causes COVID-19.Proven cases of reinfection have been extremely rare, but the most comprehensive population-based study to date suggests that the risks may be greater than scientists initially thought.The study, which drew from a register of millions of polymerase chain reaction (PCR) tests...…— by Hannah Flynn, MSAll data and statistics are based on publicly available data at the time of publication.

— by Rita Ponce, Ph.D.A study in mice suggests that the “glymphatic system,” which removes the brain’s toxic waste during sleep, may not operate efficiently in shift workers who sleep during the day. This may explain their increased risk of brain disorders, such as Alzheimer’s disease.In 2012, researchers at the University of Rochester Medical Center (URMC), NY, discovered a previously unknown waste disposal system in the brain.They dubbed it the because nerve cells called glial cells manage its operation, which fulfills a similar role for the brain that the does for the rest of the...…— by Rita Ponce, Ph.D.A study in mice suggests that the “glymphatic system,” which removes the brain’s toxic waste during sleep, may not operate efficiently in shift workers who sleep during the day.
