Image processing for applications in artificial vision
For a robot to identify objects in a particular image, it is first necessary that it can "see" them. With this aim, in artificial vision, edge detectors are normally used, i.e. computer programmes that delimit the objects in an image and define the limits between them and the background, and between the different objects themselves. view more (2006-01-17)
Designer molecule detects tiny amounts of cyanide, then glows
A small molecule designed to detect cyanide in water samples works quickly, is easy to use, and glows under ultraviolet or "black" light. view more (2009-10-22)
Cone-Beam CT faster, potentially more accurate than conventional mammography
Cone-beam breast CT provides exceptional tissue contrast and can potentially reduce examination time with comparable radiation dose to conventional 2D mammography, according to a new study by a team of researchers from the University of Texas M. D. Anderson Cancer Center in Houston. view more (2007-12-28)
Cardiff researchers could herald a new era in fundamental physics
Cardiff University researchers who are part of a British-German team searching the depths of space to study gravitational waves, may have stumbled on one of the most important discoveries in physics according to an American physicist. view more (2009-02-04)
2 for 1: NIST design enables more cost-effective quantum key distribution
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a simpler and potentially lower-cost method for distributing strings of digits, or "keys," for use in quantum cryptography, the most secure method of transmitting data. view more (2008-05-30)
CT imaging with use of novel contrast agent may predict heart attack in waiting
A new imaging technology may hold the key to not only stopping heart attacks in their tracks but also preventing them for ever occurring. view more (2007-04-10)
Researchers use novel three-dimensional imaging technique
Using an innovative three-dimensional imaging technique, a team of UCLA researchers have tracked how Alzheimer's disease spreads through the hippocampus - the area of the brain linked with memory - in a pattern consistent with the known trajectory of neurofibrilliary tangle dissemination, an accumulation of diseased proteins in the brain cells. view more (2006-10-26)
Imaging technique sheds new light on the composition of the brain of moderate cannabis users
Diffusion tensor imaging, a newly developed magnetic resonance imaging technique, could enable researchers to gain a better understanding of the effects of cannabis on the brain. view more (2006-05-08)
The Midnight Ride of the CMS Tracking Detector
Scientists of the U.S. CMS collaboration today (Dec. 20) joined colleagues around the world in announcing the successful installation of the world's largest silicon tracking detector at CERN in Geneva, Switzerland. view more (2007-12-21)
UC Riverside physicists contribute to state-of-the-art detector installed in Switzerland
UC Riverside scientists led by Gail Hanson, a distinguished professor of physics, are part of a collaboration of approximately 2300 international physicists who announced Dec. 19 that the world's largest silicon tracking detector at CERN in Geneva, Switzerland, had been successfully installed. view more (2007-12-21)
Einstein's relativity survives neutrino test
Physicists working to disprove "Lorentz invariance" -- Einstein's prediction that matter and massless particles will behave the same no matter how they're turned or how fast they go -- won't get that satisfaction from muon neutrinos, at least for the time being, says a consortium of scientists. view more (2008-10-16)
New technique improves outcome for living donor liver transplants
The University of Alberta Hospital (UAH) is one of only a few centers in Canada that perform living donor liver transplantation, a surgical procedure developed in the late 1980s that expands the organ donor pool. About 80 liver transplants are done a year in Alberta, 10 of those being living-donor. view more (2008-03-19)
New imaging technique could promote early detection of multiple sclerosis
Researchers from Purdue University have studied and recorded how myelin degrades real-time in live mice using a new imaging technique. Myelin is the fatty sheath coating the axons, or nerve cells, that insulate and aid in efficient nerve fiber conduction. In diseases such as multiple sclerosis, the myelin sheath has been found to degrade. view more (2007-06-28)
Using light under your skin
You have a tiny wound on your hand that doesn't heal, a bad burn on your chest - or an injured retina. Your doctor cannot tell how serious the injuries are below the surface. He needs tissue samples. That means using a scalpel, which again equals pain, perhaps even a risk. Soon there may be hope for an improved and totally harmless method to peer... view more... (2005-04-21)
Blue laser - the alpha and the omega
The future of DVD is blue. New, low-cost optical laser technology generates short-wavelength beams. At the other end of the beam are detector heads that will soon contain arrays of up to 25 sensors. Two Fraunhofer Institutes are taking the lead at both ends of the spectrum. Man's appetite seems to be insatiable. In the dark ages, packing away... view more... (2004-05-14)
MRI/PET Scanner Combo
Two kinds of body imaging -- positron emission tomography (PET) and magnetic resonance imaging (MRI) -- have been combined for the first time in a single scanner. view more (2008-03-10)
Physicists step closer to understanding origin of the universe
The world's largest particle detector is nearing completion following the construction of its 'endcap' at the University of Liverpool. view more (2006-02-22)
MIT device could prevent epileptic seizures
Researchers at MIT are developing a device that could detect and prevent epileptic seizures before they become debilitating. view more (2006-09-13)
New experiment could reveal make-up of the universe
The detectors will become part of the Advanced Gamma Tracking Array (AGATA) experiment, currently based in Italy, which aims to create a 'fingerprint' of the inside of the atomic nucleus to understand the structure of all matter in the Universe, including human beings and the stars. view more (2009-08-06)
A Single-Photon Server with Just One Atom
Every time you switch on a light bulb, 10 to the power of 15 (a million times a billion) visible photons, the elementary particles of light, are illuminating the room in every second. If that is too many for you, light a candle. view more (2007-03-13)
