High-speed 'label-free' imaging could reveal dangerous plaques Posted: 04 Nov 2014 03:37 PM PST Researchers are close to commercializing a new type of medical imaging technology that could diagnose cardiovascular disease by measuring ultrasound signals from molecules exposed to a fast-pulsing laser.

Novel nanofiber-based technology could help prevent HIV/AIDS transmission Posted: 04 Nov 2014 03:37 PM PST Scientists have developed a novel topical microbicide loaded with hyaluronic acid nanofibers that could potentially prevent transmission of HIV through the vaginal mucosa.

Google Glass may partially obstruct peripheral vision, study finds Posted: 04 Nov 2014 01:30 PM PST Testing of study participants who wore head-mounted display systems -- Google Glass -- found that the glasses created a partial peripheral vision obstruction, according to a study.

Digital dinosaurs: New research employs high-end technology to restore dinosaur fossil Posted: 04 Nov 2014 01:30 PM PST Scientists employed high-resolution X-ray computed tomography and digital visualization techniques to restore a rare dinosaur fossil. The focus of the study was the skull of Erlikosaurus andrewsi, a 3-4 meter large herbivorous dinosaur called a therizinosaur, which lived more than 90 million years ago during the Cretaceous Period in what is now Mongolia.

Disorder plus disorder equals more disorder? Posted: 04 Nov 2014 11:17 AM PST It turns out that in certain situations, combining messes can actually reduce the disorder of the whole; an international team of researchers has identified a set of conditions in which adding disorder to a system makes it more orderly. This behavior is known as antifragility, a concept introduced recently to describe similar phenomena in statistics, economics and social science.

Granger Causality test can make epilepsy surgery more effective Posted: 04 Nov 2014 09:11 AM PST A new statistical test that looks at the patterns of high-frequency network activity flow from brain signals can help doctors pinpoint the exact location of seizures occurring in the brain and make surgery more effective, according to researchers.

Dark matter may be massive: Theorists suggest the standard model may account for the stuff Posted: 04 Nov 2014 08:16 AM PST Instead of WIMPS or axions, dark matter may be made of macroscopic objects as small as a few ounces up to the size of a good asteroid, and probably as dense as a neutron star or the nucleus of an atom, researchers suggest.

Radiation a risk factor for brain tumors in young people, study finds Posted: 04 Nov 2014 08:11 AM PST In people under age 30, radiation is a risk factor for a type of brain tumor called a meningioma, a study has found. Researchers analyzed records of 35 patients who were diagnosed with meningiomas before age 30. Five had been exposed to ionizing radiation earlier in their lives. They include two patients who received radiation for leukemia at ages 5 and 6; one who received radiation at age 3 for a brain tumor known as a medulloblastoma; and one who received radiation for an earlier skull base tumor that appeared to be a meningioma. The fifth patient had been exposed at age 9 to radiation from the Chernobyl nuclear power plant disaster in Ukraine.

Hydrogel: Patent issued for substance with medical benefits Posted: 04 Nov 2014 08:11 AM PST A U.S. patent has been awarded to a novel jelly-like substance called a hydrogel. This substance may be used for biomedical applications, ranging from cell culture and drug delivery to repairing and replacing tissue, organs and cartilage.

Physicists narrow search for solution to proton spin puzzle Posted: 04 Nov 2014 08:11 AM PST Results from recent experiments reveal new insights about how quarks and gluons, the subatomic building blocks of matter, contribute to proton "spin."

Outsmarting thermodynamics in self-assembly of nanostructures Posted: 04 Nov 2014 06:11 AM PST Researchers have achieved symmetry-breaking in a bulk metamaterial solution for the first time, a critical step game toward achieving new and exciting properties in metamaterials.

Mobile networks: 5G is not 4G+1 Posted: 04 Nov 2014 06:10 AM PST Recently, Spaniards had to re-tune all television sets as a result of the introduction of 4G mobile networks. Their data transmission speed (10 times higher than the 3rd generation's) required a release of the frequency band hitherto occupied by several TDT channels. 4G is a fact, but we are nearing the 5G revolution. 5G network development is now underway to provide a network capacity one thousand times higher than that of existing mobile networks. But, what is 5G? How will it impact our lives and when will it become available? Who is going to make possible this leap in communications technology?

Researchers advocate for optimum level of 'unequality' for the US economy Posted: 04 Nov 2014 05:38 AM PST The growing disparity in economic inequality has become so stark that even Janet Yellen, Federal Reserve chairwoman, recently expressed concern. Interestingly, new research has discovered that American citizens desire an unequal, but more equal distribution of wealth and income. Lower levels of this 'unequality' are associated with decreased unethical behavior and increased motivation and labor productivity.

'Grimsel' electric racing car breaks world record Posted: 04 Nov 2014 05:37 AM PST The 'Grimsel' electric racing car today broke the previous world record for acceleration in electric cars. The vehicle accelerated from 0 to 100 km/h in 1.79 seconds in under 30 meters. The new record was set by the students who also designed and built the vehicle.

Six faces of killers on social networking sites revealed Posted: 04 Nov 2014 05:37 AM PST A team of leading criminologists have published the first-ever study on how convicted killers have used the social networking site Facebook in relation to their crimes.

A medical lab for the home Posted: 04 Nov 2014 05:37 AM PST Researchers have demonstrated a mobile wireless system that monitors the health of elderly people in their own homes, using miniature sensors. Besides non-invasive sensors this platform integrates technology to take a blood sample and to determine specific markers in the patient's blood. At its core is the home unit, a compact device located in the patient's home. It incorporates the necessary software as well as sensors and the analytical equipment.

Scientists invent tool to improve usability of mobile devices Posted: 04 Nov 2014 05:31 AM PST The rapid increase in mobile technology such as smart phones and watches, tablets and Google Glass, has resulted in the need for more research to ensure those devices work well. But, say experts, there are no good tools to properly test mobile devices. So they invented a solution using the latest technology of Google Glass.

Better bomb-sniffing technology Posted: 04 Nov 2014 05:31 AM PST Engineers have developed a new type of carbon nanotube material for handheld sensors that will be quicker and better at sniffing out explosives, deadly gases and illegal drugs.

Study recommends integrating housing data with health data to improve patient medical care Posted: 03 Nov 2014 04:20 PM PST Integrating community housing data on such code violations as mold and cockroaches with health data can identify at-risk geographical areas of medical concern and help target patients for medical interventions, a study has demonstrated.

Inexpensive, easy way to filter arsenic from water Posted: 03 Nov 2014 11:22 AM PST A quick, cheap and easy way has been developed to filter from water one of the world's most common pollutants: arsenic. Arsenic is one of the most common environmental pollutants, finding its way into drinking water supplies through natural or humanmade sources and affecting millions of people worldwide. It has been shown to cause cancer and new methods to remove arsenic from drinking water and wastewater are urgently needed.
