Using physics to improve root canal efficiency

Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature ...

Liquid crystals create easy-to-read, color-changing sensors

Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or contract, changing how the nanocrystals ...

Daytime aardvark sightings are a sign of troubled times

Aardvarks occur across most of sub-Saharan Africa, but very few people have seen one, because they are solitary, mostly active at night, and live in burrows. They use their spade-like claws to build these burrows and to dig ...

Bats are hosts to a range of viruses but don't get sick – why?

Bats harbour many diverse viruses, including coronaviruses. Indeed, SARS, Mers and COVID-19—which are all caused by coronaviruses—are thought to have emerged from bats. These diseases can be deadly to humans, yet bats ...

Bird feeding helps females more than males

A new study from Lund University in Sweden shows that female birds benefit more from extra food in the winter. If females receive additional food, they do not need to reduce their body temperature as much as they would have ...
