In this video, co-author D. Fox Harrell discusses “Reimagining the Avatar Dream,” a Contributed Article in the July 2017 Communications of the ACM that argues for the need to reconsider the social and cultural impacts of creating social networks based on virtual identities.
Scientists have developed an electronic sensor that is hypoallergenic, breathable and can be worn constantly for a week, enabling continuous, unobtrusive health monitoring.
The patch, developed by scientists at the University of Tokyo, is, according to its creators, so thin and light that the majority of users will forget they are even wearing it – a far cry from many of the weighty or uncomfortable health monitoring solutions currently available.
Designed to withstand repeated and continuous bending and stretching, the patch can be worn during a host of day-to-day activities, including sports. As a result its creators believe it could be used not only in healthcare settings, but also to monitor professional athletes.
Researchers from China successfully teleported a photon from Earth to a satellite 500 km away. The work is an essential step towards establishing a global-scale quantum internet.
Not long ago, in the early 1990s, scientists only speculated that teleportation using quantum physics could be possible. Since then, the process has become a standard operation in quantum optics labs around the world. In fact, just last year, two separate teams conducted the world’s first quantum teleportation outside of a laboratory.
