More than 37,000 years of infectious diseases in humans have been mapped by scientists, with academics pointing to one particular behaviour from our ancestors as playing a “key role” in their spread. Involving researchers linked to British; Danish; Swedish; German; Italian, and Australian universities, the study saw them analyse DNA from more than 1,300 prehistoric humans dating back as far …

Significant brain defects known as Chiari malformations could be down the genes some of us have inherited from Neanderthals, according to a new study, causing a mismatch between brain shape and skull shape. The study focuses on Chiari malformation type I (CM-I), where the lower part of the brain extends too far into the spinal cord – typically linked to …

Using ancient DNA recovered from prehistoric bones and teeth, scientists have built a 37,000‑year timeline of human infections, stretching from the icy mammoth camps of Siberia to medieval graveyards in Denmark. The new genetic map shows how early microbes began shaping human history. The scientists sequenced remains from 1,313 individuals and found genetic traces of 214 different pathogens. These range …

To most cat lovers, the soothing sound of a purr is more than background noise—it’s a soft, rhythmic expression of trust, contentment and connection. But a new study suggests there may be something deeper behind your cat’s purring habits. In fact, the key to that comforting hum might be found in their genes. Researchers from Kyoto University in Japan, publishing …

On June 12, 2025, an Air India flight crashed shortly after takeoff, killing 260 people. The plane was carrying over 33,000 gallons (125,000 liters) of fuel, leading to a massive fire, and several bodies were charred beyond recognition, fragmented or otherwise rendered unrecognizable. To identify the bodies, officials sought DNA samples from the victims’ family members. More than two weeks …

Sled dogs have been performing a vital role for people living in the Arctic for 9,500 years. In fact, the ubiquity of these dogs across the polar region is a testament to their significance. While there are various breeds of sled dog today, one breed is not only the oldest among them, it may well be the oldest dog breed …

An experimental gene therapy for high cholesterol is showing promise in clinical trials and inching closer to approval. The treatment, called VERVE-102, is being tested in people with familial hypercholesterolemia (FH), an inherited condition that raises the levels of low-density lipoprotein (LDL) cholesterol — the “bad” kind — in the blood. It’s also being tested in people with premature coronary …
