NASA: Hubble Camera's Repair a Partial Success
An ambitious spacewalk repair to Hubble's main camera has met with partial success.
World's Fastest Camera Relies On Entirely New Type Of Imaging
Scientists have developed an entirely new approach to imaging that does not require a CCD or CMOS camera. Building on more than a decade of research on photonic time stretch,...
Flame Off!: Turning Natural Gas Pollution into Gasoline
As if burning oil and all of its derivatives wasn't bad enough for the environment, there's also the natural gas that bubbles up as the oil is pumped out. This...
'Sleep Talking' PCs Save Energy And Money
Personal computers may soon save large amounts of energy by "sleep talking." Computer scientists have created a plug-and-play hardware prototype for personal computers that induces a new energy saving state...
Atomic physics study sets new limits on hypothetical new particles
In a forthcoming Physical Review Letters article, a group of physicists at the University of Nevada, Reno are reporting a refined analysis of experiments on violation of mirror symmetry in...
Nanoneedle is small in size, but huge in applications
Researchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. In...
Nanophysicists find unexpected magnetic effect
Spanish and U.S. physicists studying nanoelectronics have found that size really does matter when it comes to predicting the behaviour of electrical contacts that are just one atom wide...
New Control System Has What it Takes to Guide Experimental Aircraft
When a jet is flying faster than the speed of sound, one small mistake can tear it apart. And when the jet is so experimental that it must fly unmanned,...
Toward giving artificial cells the ability for sustained movement (w/Video)
Scientists in Japan are reporting an advance toward giving artificial cells another hallmark of life -- the ability to tap an energy source and use it to undergo sustained movement....
World’s first ‘naked’ uranium-transition metal bond formed
The first unsupported uranium-rhenium bonds have been created by UK scientists
New Hope For Biomass Fuels: Breaking The Ties That Bind
Researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. The insight ultimately could lead to a...
New Concrete Heals Itself
A concrete material developed at the University of Michigan can heal itself when it cracks. No human intervention is necessary---just water and carbon dioxide.
Achieving optimal efficiencies for nanoengines
(PhysOrg.com) -- "There's a lot of recent interest in understanding the functioning and optimal performance of small systems," Katja Lindenberg tells PhysOrg.com. Lindenberg is a scientist in the Department...
DIY 'tinkerers' create more than mere toys from spare parts
To Ken Delahoussaye, an old computer, cell phone, camera or even a child's toy is much more than a disposable device. Each is something he can take apart and fuse...
