Key factor identified that makes worms feel full after a good meal

In nematode worms, a key controller allows the worm to sense when it needs food and when it feels full, and then changes its behavior accordingly. Jennifer Tullet of the University of Kent and colleagues report these new ...

A new strategy for pooling COVID-19 tests to detect outbreaks early

Researchers have proposed a new quantitative strategy for pooling COVID-19 tests in order to monitor spread and detect outbreaks early within closed communities, such as nursing homes or universities. Vincent Brault of Université ...

Soft robot swims in the Mariana Trench

A team of researchers affiliated with multiple institutions in China has developed a soft robot that can successfully swim in the Mariana Trench. In their paper published in the journal Nature,, the group describes their ...
