Japanese regulators just quietly gave researchers there a historic OK to generate human embryos from stem cells in the lab — no ovaries or testes needed. Scientists in Japan and around the world are quickly working toward making viable human eggs and sperm from stem cells, a process called in vitro gametogenesis, or IVG. Those stem cell-derived sperm and eggs …

Roughly 2.6 million-year-old fossilized teeth found in Ethiopia might belong to a previously unknown early human relative, researchers say. The teeth are from a species of Australopithecus, the genus that includes Lucy (A. afarensis). But these newly discovered teeth don’t appear to belong to any known species of Australopithecus, according to a new study published in the journal Nature on …

I’m not a medical person but my mum was a midwife before she retired. She told me about the septum primum and has always referred to it as the most amazing thing about human development that continues to blow her mind. In short, it’s a valve in the heart that develops when in the womb. It allows blood to bypass …

Groundbreaking research led by a Swansea University academic has revealed a synthetic glycosystem – a sugar-coated polymer nanoparticle – that can block Covid-19 from infecting human cells, reducing infection rates by nearly 99%. The glycosystem is a specially designed particle that mimics natural sugars found on human cells. These sugars, known as polysialosides, are made of repeating units of sialic …

A tiny blob of gelatinous tissue sitting in a dish represents a giant leap forward in human brain research. Known as an organoid, it’s a living 3D model of a human organ; one of the first to constitute multiple different regions of the brain. Moreover, those regions connect up with each other and light up with neuronal activity, comparable to …

New York City’s ongoing outbreak of Legionnaires’ disease in Central Harlem, which has killed three people and sickened dozens more, is the latest in a series of similar clusters that have made headlines in recent years, usually in the summer months. Legionnaires’ experts say a number of environmental and human factors are likely behind a recent rise in reported cases …
