In April of 2025, headlines across the world announced that the dire wolf had been brought back from extinction. This 130-150 lbs wolf species, about 25% heavier than modern-day gray wolves, had not ...

Much of what shapes people’s lives happens at an unseen level—it comes down to DNA. This year, The Scientist explored genetic insights into how individuals smell, metabolize alcohol, and even how ...

Genetic research does not always produce tidy answers. Sometimes it reveals traces that raise more questions than they settle. In recent years, scientists studying human DNA identified genetic signals ...

Scientists have uncovered a powerful genetic switch that helps some of the body’s most important immune cells grow up properly and keep our organs healthy. The switch, called MafB, guides immature ...

Weizmann Institute study finds genetics may account for about 50 percent of human lifespan, more than double previous estimates.

Most organisms on Earth have the same basic genetic code, but it comes with some flaws. Scientists sought to work out those errors by creating their own artificial genome, which replaced E. coli’s ...

A rare genetic mutation that causes a deficiency in an immune regulator called ISG15 is known to make people more vulnerable to some bacterial infections and cause persistent inflammation — but it can ...

Genetic inheritance may sound straightforward: One gene causes one trait or a specific illness. When doctors use genetics, it’s usually to try to identify a disease-causing gene to help guide ...

For decades, scientists have theorized that two genetic defects have the potential to essentially “cancel each other out,” restoring normal protein function in the process. A new study confirms this ...
