Research team uses tunable laser to develop straightforward broadband spectroscopy method with Hz-level precision
Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser technology have further enhanced its capabilities. Th.....»»
Arctic Ocean may absorb less CO₂ than projected due to coastal erosion
As Earth warms, the Arctic Ocean's ability to absorb carbon dioxide from the atmosphere is waning due to melting permafrost and worsening coastal erosion, according to new research......»»
Don’t call it boring — this printer was an absolute joy to use
I reviewed HP's Color LaserJet Pro 4201dw to find out if this affordable color laser printer has good quality and long-term value......»»
3D laser printing with bioinks from microalgae
Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as "biofactories" for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigm.....»»
Invisible laser beam detects what a MacBook user is typing
A whitehat hacker has demonstrated the use of an invisible laser beam to detect what a MacBook user is typing, from a distance, through a window, without being able to see the keyboard … more….....»»
Weather "whiplash" in Antarctica may help predict effects of future climate change
The McMurdo Dry Valleys of Antarctica live up to their name. The region is one of the driest places on Earth—mountains form a wall around the valleys and prevent melting glacier water from intruding, humidity is extremely low, and no rain was docum.....»»
Hazardous Melting Ice Could Sink Arctic Shipping
Warmer temperatures were supposed to make Arctic shipping easier. But thick floating ice created by local melting is a bigger risk than people realized.....»»
Retreating Andean rocks signal the world"s glaciers are melting far faster than predicted, report scientists
Rocks recently exposed to the sky after being covered with prehistoric ice show that tropical glaciers have shrunk to their smallest size in more than 11,700 years, revealing the tropics have already warmed past limits last seen earlier in the Holoce.....»»
3D terrestrial laser scanner assists in reconstructing glacier"s mass balance sequence
Complex topography of glacier surfaces under accelerating global warming presents unprecedented challenges to traditional methods of glaciological observation due to intense fragmentation and differential melting......»»
Can quantum particles mimic gravitational waves?
When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (L.....»»
Underwater mapping reveals new insights into melting of Antarctica"s ice shelves
An international research team—including scientists from the University of East Anglia (UEA)—deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica. The underwater vehicle, "Ran," was programmed to dive into the cavity.....»»
NASA, JAXA bounce laser beam between moon"s surface and lunar orbit
