Earliest crafted bone tools date back 1.5 million years

•
00:46 Ancient humans made bone tools 1.5 million years ago

A 1.5-million-year-old cache of animal-bone tools reveals that ancient humans systematically crafted with this material much earlier than previously thought. Researchers uncovered 27 bone artefacts in Tanzania honed into sharp tools almost 40 cm long. This discovery pushes back the dedicated manufacture of bone tools by around a million years and could have helped these early humans develop new kinds of technology. “This raises a lot of interesting questions,” says study author Ignacio de la Torre.

11:45 A trove of antibacterial molecules hidden in human proteins

To help protect against infection, cells in the body will selectively cut proteins to produce molecules known as antimicrobial peptides, according to new research. A team has found that many potential peptides appear to be locked up within proteins — to get them out, cells shift the activity of a waste-disposal system called the proteasome, known for its role in protein degradation and recycling. In tests, one of these peptides showed efficacy at protecting mice from infection, indicating that these molecules could one day have therapeutic potential.
