A new device that fits over a person s ears and enables non-invasive measurement of real-time changes in blood alcohol levels through the skin is presented in a proof-of-principle study in Scientific Reports. ....
It is generally agreed that sperms swim by beating or rotating their soft tails. However, a research team led by scientists from City University of Hong Kong (CityU) has discovered that ray sperms move by rotating both the tail and the head. The team further investigated the motion pattern and demonstrated it with a robot. Their study has expanded the knowledge on the microorganisms motion and provided inspiration for robot engineering design. ....
MIT biological engineers have demonstrated a way to easily retrieve data files stored as DNA. This could be a step toward using DNA archives to store enormous quantities of photos, images, and other digital content. ....
E-Mail Washington, D.C. - June 9, 2021 - The Pfizer COVID-19 vaccine is protective against several SARS-CoV-2 variants that have emerged, according to new research presented in the journal mBio, an open-access journal of the American Society for Microbiology. While this is good news, the study also found that the only approved monoclonal antibody therapy for SARS-CoV-2 might be less effective against SARS-CoV-2 variants in laboratory experiments. The vaccines provide very strong protection against the earlier forms of the virus as well as the newer variants. This is an important point because I have heard people say that they don t think there is a reason to get vaccinated, because the vaccine isn t going to work against the variants, but that is not true the vaccine will work against the variants, said Nathaniel Ned Landau, Ph.D., professor in the Department of Microbiology at the NYU Grossman School of Medicine, in New York City. ....

Many animals have evolved camouflage tactics for self-defense, but some butterflies and moths have taken it even further: They ve developed transparent wings, making them almost invisible to predators. A team led by Marine Biological Laboratory (MBL) scientists studied the development of one such species, the glasswing butterfly, Greta oto, to see through the secrets of this natural stealth technology. Their work was published in the ....
