An extinct rat shows CRISPR’s limits for resurrecting species
Before the early 1900s, if it walked like a Christmas Island rat and talked like a Christmas Island rat, it probably was a Christmas Island rat. But if one of…
Africa’s oldest human DNA helps unveil an ancient population shift
Ancient Africans in search of mates traded long-distance travels for regional connections starting about 20,000 years ago, an analysis of ancient and modern DNA suggests. That shift occurred after treks…
Gene therapies for sickle cell disease come with hope and challenges
Today, it’s clear that our genes not only cause many diseases, but also hold potential cures. But that wasn’t always the case. It wasn’t until 1949 that scientists first found…
How the Human Genome Project revolutionized understanding of our DNA
In October 1990, biologists officially embarked on one of the century’s most ambitious scientific efforts: reading the 3 billion pairs of genetic subunits — the A’s, T’s, C’s and G’s…
How one scientist aims to boost Black people’s representation in genetic datasets
Nearly two decades after researchers assembled the first genetic blueprint for human life, our understanding of our instruction manual has a dramatic and problematic bias: It’s based primarily on white…
Scientists are arguing over the identity of a fossilized 10-armed creature
An ancient cephalopod fossil may be about to rewrite octopus history, but it depends on who you ask. At the very least, it’s offering up a lesson in how hard…
Gory footage confirms orca pods can kill adult blue whales
Killer whales are skilled assassins, hunting everything from herring to great white sharks. Now, for the first time, scientists witnessed a pod of killer whales bring down the world’s largest…
A new particle accelerator aims to unlock secrets of bizarre atomic nuclei
Inscribed on an Italian family’s 15th century coat of arms and decorating an ancient Japanese shrine, the Borromean rings are symbolically potent. Remove one ring from the trio of linked…
Doubt cast on theorized ‘sterile’ particles leaves a neutrino mystery unsolved
For decades, physicists have suspected an interloper. A reclusive, hypothetical subatomic particle might be creeping into studies of neutrinos, nearly massless particles with no electric charge. A new study casts…
