Current World Health Organisation (WHO) guidelines typically recommend 2–7 days of abstinence before taking semen samples or assisted reproduction.

Packaged foods offer convenience for families and individuals, but they can be a major source of saturated fat, sodium and added sugars, which when consumed in excess contribute to chronic disease. To help people build healthier diets, the U.S. Food and Drug Administration proposed a new front-of-package nutrition label in January 2025 that would inform consumers about the presence of these nutrients.

While the FDA works to finalize the label, a research team led by the University of California, Davis, suggested a design that highlights products that are high in added sugar, sodium or saturated fat. They suggest in a new study an easy-to-understand label that make the healthfulness of foods more apparent.

Researchers developed a web-based intervention to educate people with cancer about the impact genetic variants can have on their family. It includes education and decision support to help patients feel comfortable communicating genetic testing information to their relatives. The platform also allows patients to invite first- and second-degree relatives to the site. Relatives get information about genetic risk, tools to help them decide if they want to receive genetic testing and access to testing.
