Physicists at the University of Southampton have tested and proven a 50-year-old theory for the first time using electro-magnetic waves. They have shown that the energy of waves can be increased by bouncing "twisted waves"—those ...

Starting with the direct detection of gravitational waves in 2015, scientists have relied on a bit of a kludge: they can only detect those waves that match theoretical predictions, which is rather the opposite way that science ...
A team at NASA's Glenn Research Center in Cleveland has streamed 4K video footage from an aircraft to the International Space Station and back for the first time using optical (laser) communications. The feat was part of ...
