Law of physics governs airplane evolution
Researchers believe they now know why the supersonic trans-Atlantic Concorde aircraft went the way of the dodo—it hit an evolutionary cul-de-sac.
LEDs made from 'wonder material' perovskite
(Phys.org) —Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future.
New mechanism converts natural gas to energy faster, captures CO2
(Phys.org) —North Carolina State University researchers have identified a new mechanism to convert natural gas into energy up to 70 times faster, while effectively capturing the greenhouse gas carbon dioxide ...
Cause of LED efficiency droop finally revealed: Auger recombination responsible
(Phys.org)—Researchers at University of California, Santa Barbara, in collaboration with colleagues at the École Polytechnique in France, have conclusively identified Auger recombination as the mechanism ...
Multiview 3-D photography made simple
Computational photography is the use of clever light-gathering tricks and sophisticated algorithms to extract more information from the visual environment than traditional cameras can.
Cirrus clouds form around mineral dust and metallic particles, study finds
At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 ...
'Temporal cloaking' could bring more secure optical communications
(Phys.org) —Researchers have demonstrated a method for "temporal cloaking" of optical communications, representing a potential tool to thwart would-be eavesdroppers and improve security for telecommunications.
Trawling for fish and scooping up public opinion
The idea of bycatch, or marine creatures being unintentionally captured by commercial fishing gears, has long proved to be a point of contention for the Australian public.
Virgin crash sets back space tourism by years: experts
The deadly crash of Virgin Galactic's spacecraft has dealt a devastating setback to the cause of space tourism, delaying the first commercial flights to the stars by years, experts said Friday.
Scientists 'bend' elastic waves with new metamaterials that could have commercial applications
Sound waves passing through the air, objects that break a body of water and cause ripples, or shockwaves from earthquakes all are considered "elastic" waves. These waves travel at the surface or through a ...
Who really benefits from the 'internet space race'?
In the film Elysium, the ultra-rich have left an apocalyptic Earth ravaged by global warming and overpopulation. Their utopian colony orbits high above Earth which festers below. Science fiction, but Silicon ...
Chinese airline completes cooking oil fuel flight
A Chinese airline on Saturday completed the country's first commercial flight using biofuel, made from waste cooking oil, as the government seeks to promote greater environmental sustainability.
