A device has been built that relies on a solid-state phenomenon called the elastocaloric effect to produce cooling to temperatures below 0 °C, lower than existing room-temperature elastocaloric cooling systems are able to achieve. The innovation demonstrates that elastocaloric technology could offer an alternative to conventional freezing systems that use volatile greenhouse gases.

Recapitulating the complexity of human organs in vitro would accelerate drug discovery and enable personalized treatments. By combining different types of liver cell from donor tissues, in vitro models of a liver region that mirror some of the organ’s main structures and functions can be assembled, getting closer to reproducing mini livers in vitro.

Viral DNA that is usually dismissed when sequencing the human genome could help to uncover useful information about complex diseases.

Numerical simulations provide a mechanism that explains how celestial objects such as stars and galaxies can generate ordered, macroscopic magnetic fields. The mechanism arises from turbulence — chaotic changes in the pressure and velocity of fluid — and avoids a physical effect that hinders other proposed systems from explaining observed ordered fields.
