While technology has made the world “smaller,” it has also pulled individuals apart, thanks to mobile phones and other devices that command our attention. Cornell University researchers are using technology, in the form of a mirror-equipped robot, to help bring people together. Members of the Architectural Robotics Lab, led by Keith Evan Green, have built a four-foot-tall robot—dubbed MirrorBot—with dual mirrors that, when placed in front of a pair of strangers, let each participant see themself in one mirror and the other person in the other.

In a study involving participants in a waiting-room setting, MirrorBot spurred conversations, playful excha...

People with long COVID are at increased risk of developing cardiovascular disease, according to a new study from Karolinska Institutet published in eClinicalMedicine. The results show that the risk of conditions such as cardiac arrhythmias and coronary artery disease is higher even among those who were not hospitalized during the acute infection.

Long COVID has become an increasingly significant health problem worldwide, and a growing number of studies suggest that the condition can lead to secondary cardiovascular diseases. To date, research has mainly focused on people who were hospitalized, while the risks for those who stayed at home or were treated at a GP are less well known...

The electronics inside your phone, your car, and every satellite currently orbiting Earth share one critical weakness: heat. Push them past about 200 degrees Celsius and they start to fail. For decades, that thermal ceiling has been one of the hardest walls in engineering. Now a team at the University of Southern California may have just found a way around it.

In a study published in Science, researchers led by Joshua Yang, Arthur B...
