Discovery of a gene in multiple mammalian species could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.

Exposure to female odors and pheromones causes weight loss and extend the life spans of mice, which may have implications for humans, researchers have found. While it was already known that sensory cues in humans and animals influence the release of sex hormones, this study shows that these cues could have more wide-spread physiological effects on metabolism and aging.

Researchers have found that people infected with HIV who receive antiretroviral therapy form antibodies against Sars-Cov-2 after being vaccinated against COVID with mRNA vaccines. Their immune response to the vaccination is, however, less strong than that of healthy people. A third vaccination reduces this gap.
