Quantum communication networks show great promise in becoming a highly secure communications system. By carrying information with photons or atoms, which are entangled so that the behavior of one affects the other, the network can easily detect any eavesdropper who tries to tap the system.
Physicists at the Georgia Institute of Technology have just reached an important milestone in the development of these systems by entangling a photon and a single atom located in an atomic
Recruitment has started on the first UK course to train medical care practitioners to manage some of the caseload of GPs, thus improving patient access to treatment.
The Postgraduate Diploma in Medical Care Practice, the first of its kind to be offered by a British university, is to be run by the University of Hertfordshire in collaboration with East and North Hertfordshire NHS Trust. It has been designed to fit the curriculum framework developed under the leadership of the Royal
Research into a new treatment for nerve damage caused by diabetes could bring relief to millions of diabetic patients, say experts.
The treatment might also reduce the number of amputations of toes and feet if early effects on nerve protection and regeneration are borne out long-term. Nerve disease in diabetes is the major cause of non-traumatic lower limb amputations in Europe and North America.

On August 10th 2005 NASA’s Mars Reconnaissance Orbiter (MRO) will be launched from Cape Canaveral in Florida beginning its journey to the red planet. For scientists from Oxford, Cardiff and Reading it will be an intense time as it will be their third attempt to get their instrument to Mars onboard a NASA spacecraft.
The main aim of the MRO mission is to seek out the history of water on Mars. This will be accomplished by a suite of six science instruments, 3 engineering experiments a
EUREKA project E! 2635 LOGCHAIN TRANSLOG SAFETY has developed a satellite-based communications system to monitor rail freight between Europe and Asia. Geostationary and orbiting satellites integrated in a single antenna ensure a fast response mechanism to potential hazards when dangerous materials are being moved. This makes transporting goods by rail safer and more efficient than ever, while the monitoring centre itself can be situated anywhere according to need.

Brains amygdala plays pivotal role during an emotional experience, strengthening connections between neurons
A research team led by UC Irvine neuroscientists has identified how the brain processes and stores emotional experiences as long-term memories. The research, performed on rats, could help neuroscientists better understand why emotionally arousing events are remembered over longer periods than emotionally neutral events, and may ultimately find application in treatments
Computed tomographic colonography (CTC) depicts cancers and other clinically important conditions that would be missed with standard colonoscopy and at very little additional cost, according to a study in the August issue of Radiology.
“The chance of finding cancer outside the colon may be as significant as the chance of finding cancer inside the colon,” said Judy Yee, M.D., Chief of Radiology at the Veterans Affairs Medical Center and associate professor and Vice Chair of ra
Biologists have discovered that a common corn fungus is by far natures most powerful known cannoneer, blasting its spores out with a force of 870,000 times the force of gravity. Farmers need not worry about being nailed by a fungal supergun, however. The infinitesimal spore travels only two-tenths of an inch (5 millimeters) before plummeting.
Nevertheless, said the biologists, the fungus Gibberella zeae outguns the previous record holder, the fungus Pilobolus, by almost a hu
Saturns radio emissions could be mistaken for a Halloween sound track.
That is how University of Iowa researchers Bill Kurth and Don Gurnett describe their recent findings, published 23 July in the journal Geophysical Research Letters. Their research investigated sounds that are not just eerie, but also descriptive of a phenomenon similar to Earths northern lights. The study was based on data from the Cassini spacecrafts radio and plasma wave science instrume
Researchers pinpoint chromosome region and genetic markers for macular degeneration in humans, rhesus monkeys
Age-related macular degeneration is the leading cause of blindness in older adults, yet researchers are still in the dark about many of the factors that cause this incurable disease.
But new insight from University of Florida and German researchers bout a genetic link between rhesus monkeys with macular degeneration and humans could unlock secrets about the earl
Ship strikes and entanglement in fishing gear are threatening the survival of the North Atlantic right whale, one of the most endangered whales with an estimated population of about 350. With eight recorded deaths in the past 16 months and a population growth rate that has declined since 1980, scientists say that unless emergency management actions are taken the population will face a catastrophic decline and become extinct.
A report in the July 22 issue of the journal Science say
A gene that appears to help regulate normal embryonic development is found at high levels in virtually all forms of breast cancer, according to a new study led by Laszlo Radvanyi, Ph.D., associate professor of breast and melanoma medical oncology at The University of Texas M. D. Anderson Cancer Center.
The finding, published in the Aug. 2, 2005, issue of the Proceedings of the National Academy of Sciences and available on-line July 25, shows that the gene, normally made in small
Novel system uses polarized light pulses to reveal crop health
By firing rapid pulses of polarized light at corn, spinach and other crops, researchers have uncovered a picture of plant health that is invisible to the naked eye. Using a portable light source and detector technology, the researchers can differentiate minute differences in leaf colors – indicators of over- or under-fertilization, crop-nutrient levels and perhaps even disease.
The researchers hope their tra
Hurricane Emilys 140-mile-per-hour winds, which last week blew roofs off hotels and flattened trees throughout the Caribbean, owed their force to an unlikely culprit – ocean spray.
According to a new study by two University of California, Berkeley, mathematicians and their Russian colleague, the water droplets kicked up by rough seas serve to lubricate the swirling winds of hurricanes and cyclones, letting them build to speeds approaching 200 miles per hour. Without the l
Tracing the larvae of marine organisms from where they were born to their ultimate destination has been regarded as one of the greatest challenges in ocean science. Managers of marine reserves areas have eagerly sought this information to help determine the optimal size and spacing of marine reserves; well-planned reserves should help ensure that protected populations can sustain themselves as well as provide a source of larvae to maintain exploited populations in areas open to fishing. In a
A mixture of bacteria developed in part by University of Alberta researchers has been proven highly effective in treating people suffering from ulcerative colitis.
The findings, published in the July, 2005 issue of American Journal of Gastroenterology showed that the majority of patients taking a probiotic mixture of 8 bacteria (VSL#3) for 6 weeks improved their ulcerative colitis. Probiotics are preparations of living microbial cells that, when ingested, are thought to posit
