Scientists have demonstrated a more advanced lightning rod than a humble metal stick. Beaming a high-powered laser into the sky was shown to deflect lightning bolts, enabling laser lightning rods that protect a wider area from dangerous strikes.
-
Researchers at Northwestern Polytechnical University in Xianyang, China, have demonstrated a drone that never needs to land, thanks to a remote charging system that delivers power via an adaptive, target-tracking laser on the ground.
-
Water is usually something you’d want to keep away from electronic circuits, but engineers in Germany have now developed a new concept for water-based switches that are much faster than current semiconductor materials.
-
Scientists investigating the potential of a non-invasive laser therapy to improve cognitive function have demonstrated an ability to boost short-term memory in human subjects by targeting specific regions of the brain.
-
A small satellite developed by MIT engineers has set a new record for data transmission between a satellite and Earth. The TeraByte InfraRed Delivery (TBIRD) system used a laser to beam huge amounts of data at up to 100 gigabits per second.
-
Physicists at the Australian National University say that optical microscopes should get a huge boost in magnification, after their discovery of a new high harmonic laser illumination technique, using a tiny cylinder 1/50th the width of a human hair.
-
New evidence has emerged in the debate about whether there’s liquid water on Mars. In a study led by the University of Cambridge, scientists examined the topology of Martian ice sheets and found signatures that match subglacial lakes here on Earth.
-
The US is all set to kick off a new era in high-powered laser experimentation this week, with scientists moving the final pieces into place for Zetawatt-Equivalent Ultrashort pulse laser System (ZEUS) at the University of Michigan.
-
Scientists have developed a way to produce a web of quantum entangled photons using a far more simple setup than usual. The key is a precisely patterned surface 100 times thinner than paper, which could replace a roomful of optical equipment.
-
Scientists have turned plastic into diamonds. Using high-powered lasers, the team zapped samples of common PET plastic, which produces intense heat and pressure to form tiny diamonds that may naturally rain down on planets like Uranus and Neptune.
-
Korean engineers have demonstrated a new system that uses infrared lasers to beam power over distances as far as 100 ft (30 m), which could eventually lead to technology that automatically charges your phone as soon as you walk into a room.
-
NASA engineers have developed a tiny but powerful laser that could one day help astronauts find water on the Moon. Smaller than a US quarter, the laser makes use of quantum mechanical effects to produce a THz beam that can highlight hidden water.
