Rice basket study rethinks roots of human culture

A new study from the University of Exeter has found that teaching is not essential for people to learn to make effective tools.

The results counter established views about how human tools and technologies come to improve from generation to generation and point to an explanation for the extraordinary success of humans as a species. The study reveals that although teaching is useful, it is not essential for cultural progress because people can use reasoning and reverse engineering of existing items to work out how to make tools.

Research shows alternating antibiotics could make resistant bacteria beatable

Pioneering new research has unlocked a new technique to help combat the rise of antibiotic-resistant bacteria, that cause debilitating and often life-threatening human illness.

Researchers from the University of Exeter has shown that the use of ‘sequential treatments’ – using alternating doses of antibiotics – might offer effective treatment against bacterial infection. (more…)

Love, love me do: male beetles that have more sex are more insecure, study shows

Males that mate more often are more insecure about their social status than those mating less, according to new research on the behaviour of burying beetles.

The study, published in the journal Evolution, provides new evidence that the social sensitivity of male behaviour is linked to how often male beetles mate. (more…)

Skeletons uncovered at Ipplepen reveals major Roman cemetery

15 ancient skeletons have been discovered on an archaeological dig in Ipplepen, a major Romano-British settlement in Devon and now the best preserved Roman cemetery. University of Exeter archaeologists and a team of students and volunteers uncovered the human remains during an excavation of a Roman Road and found a roadside cemetery, the like of which has never been seen in the region.

The significance of the discovery took on further importance when one of the skeletons was found to date from around 250 to 350 years after the Roman period, an era often referred to as the ‘dark ages’. These discoveries are of both national and regional value in providing a glimpse into Romano-British life and how the settlement continued into post-Roman times. (more…)

Doubt cast on global firestorm generated by dino-killing asteroid

Pioneering new research has debunked the theory that the asteroid that is thought to have led to the extinction of dinosaurs also caused vast global firestorms that ravaged planet Earth.

A team of researchers from the University of Exeter, University of Edinburgh and Imperial College London recreated the immense energy released from an extra-terrestrial collision with Earth that occurred around the time that dinosaurs became extinct. They found that the intense but short-lived heat near the impact site could not have ignited live plants, challenging the idea that the impact led to global firestorms. (more…)
