Research suggests Mars once had more water than Earth's Arctic ocean
A primitive ocean on Mars held more water than Earth's Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet's atmosphere.
Distant supernova split four ways by gravitational lens
Over the past several decades, astronomers have come to realize that the sky is filled with magnifying glasses that allow the study of very distant and faint objects barely visible with even the largest telescopes.
New paint-like coating makes tough surfaces that repel spills, scratches (w/ Video)
A new paint that makes robust self-cleaning surfaces has been developed by a team led by UCL researchers. The coating can be applied to clothes, paper, glass and steel and when combined with adhesives, maintains ...
Paperspace computer aims to resolve hardware distractions
Hackers threaten phone in your pocket, experts warn
The boom in smartphones among often careless users has made happy hunting for hackers, whose virus attacks and hijacking of unprotected mobiles are multiplying, experts warn.
Simulations provide new insight into emerging nanoelectronic device
Researchers have used an advanced model to simulate in unprecedented detail the workings of "resistance-switching cells" that might replace conventional memory for electronics applications, with the potential ...
Thermonuclear supernova ejects our galaxy's fastest star (w/ video)
Scientists using the W. M. Keck Observatory and Pan-STARRS1 telescopes on Hawaii have discovered a star that breaks the galactic speed record, traveling with a velocity of about 1,200 kilometers per second ...
Breakthrough in energy harvesting could power life on Mars
Martian colonists could use an innovative new technique to harvest energy from carbon dioxide thanks to research pioneered at Northumbria University, Newcastle.
Squeezable nano electromechanical switches with quantum tunneling function
A longstanding problem in designing nanoscale electromechanical switches is the tendency for metal-to-metal contacts to stick together, locking the switch in an "on" position. MIT electrical engineering graduate ...
Perfect NCAA bracket? Near impossible, mathematician says
The odds of picking a perfect bracket for the NCAA men's basketball March Madness championship tournament are a staggering less than one in 9.2 quintillion (that's 9,223,372,036,854,775,808), according to ...
New detector sniffs out origins of methane
Methane is a potent greenhouse gas, second only to carbon dioxide in its capacity to trap heat in Earth's atmosphere for a long time. The gas can originate from lakes and swamps, natural-gas pipelines, deep-sea ...
Transport molecule forms a protective structure to guide proteins to cell membrane
The molecular complex that guides an important class of proteins to correct locations in cell membranes does so by forming a dimeric structure with a protective pocket, report scientists from the University ...
Nutrient pollution damages streams in ways previously unknown, ecologists find
An important food resource has been disappearing from streams without anyone noticing until now.
Power-generating urinal pioneered in Britain
British scientists on Thursday unveiled a toilet that unlocks energy stored within urine to generate electricity, which they hope could be used to light remote places such as refugee camps.
