Portable biosensor warns of heart attack and stroke

A team of researchers from National Tsing Hua University and National Cheng Kung University, both in Taiwan, has developed a low-cost, portable medical sensor package that has the potential to alert users of medical issues ...

Researchers validate several fluctuation theorems for first time

Researchers at Purdue University have performed the first experimental tests of several fundamental theorems in thermodynamics, verifying the relationship between them and providing a better understanding of how nanoparticles ...

Swarm trio becomes a quartet

With the aim of making the best possible use of existing satellites, ESA and Canada have made a deal that turns Swarm into a four-satellite mission to shed even more light on space weather and features such as the aurora ...

Giant intrinsic chirality from planar dielectric nanostructures

Harvard researchers have developed a metasurface comprising a single planar layer of nanostructures exhibiting strong optical chirality in transmission. This means it can let circularly polarized light of one polarization ...

Recurrences in an isolated quantum many-body system

It is one of the most astonishing results of physics—when a complex system is left alone, it will return to its initial state with almost perfect precision. Gas particles, for example, chaotically swirling around in a container, ...

Developing reliable quantum computers

Quantum computers may one day solve algorithmic problems that even the biggest supercomputers today can't manage. But how do you test a quantum computer to ensure it is working reliably? Depending on the algorithmic task, ...
