Direct observation of bond formations

Science Daily - Thu, 19/02/2015 - 4:58pm
Direct "observation" of the bond making, through a chemical reaction, has been longstanding dream for chemists. However, the distance between atoms is very small, at about 100 picometer, and the bonding is completed very quickly, taking less than one picosecond (ps). Hence, previously, one could only imagine the bond formation between atoms while looking at the chemical reaction progressing in the test-tube. In this research, scientists directly observed a very fast chemical reaction, induced by photo-excitation.

Severe asthma: Gallopamil confirmed as a therapeutic approach

Science Daily - Thu, 19/02/2015 - 4:58pm
The clinical efficacy of gallopamil in 31 patients with severe asthma has been demonstrated through a new study. This chronic disease is characterized by remodeling of the bronchi, which exacerbates the obstruction of the airways already seen in 'classic' asthma. In contrast to the reference treatment, gallopamil has proved capable of reducing the bronchial smooth muscle mass.

Possible regulation of cigarettes not likely to significantly change US illicit tobacco market

Science Daily - Thu, 19/02/2015 - 4:57pm
Although there is insufficient evidence to draw firm conclusions about how the US illicit tobacco market would respond to any new regulations that modify cigarettes -- for example, by lowering nicotine content -- limited evidence suggests that demand for illicit versions of conventional cigarettes would be modest, says a new report.

Researchers wind up a 40 year old debate on betaretrovirus infection in humans

Science Daily - Thu, 19/02/2015 - 4:57pm
New light has been shed on primary biliary cirrhosis, a rare liver disease that affects up to one in 500 middle aged women. In a study, researchers demonstrate that patients with the disease are infected with human betaretrovirus -- a virus resembling a mouse mammary tumor virus.

Statins may not lower Parkinson's risk, experts say

Science Daily - Thu, 19/02/2015 - 4:57pm
The use of statins may not be associated with lowering risk for Parkinson's disease, according to a new study. The findings cast doubts on reports suggesting that the cholesterol-lowering medications may protect against this neurodegenerative brain disorder.

New NIST tools to help boost wireless channel frequencies and capacity

Science Daily - Thu, 19/02/2015 - 4:56pm
To help solve growing problems with wireless bandwidth crowding and support the next generation of mobile technology, researchers are developing measurement tools for channels that are new for mobile communications and that could offer more than 1,000 times the bandwidth of today's cell phone systems.

A new view of the solar system: Astrophysical jets driven by the sun

Science Daily - Thu, 19/02/2015 - 4:56pm
New research suggests that the sun's magnetic field controls the large-scale shape of the heliosphere much more than expected. The new model shows that the magnetic field squeezes the solar wind along the sun's north-south axis, producing two jets. These jets are then dragged downstream by the flow of the interstellar medium -- the gases and dust that lie between star systems.

Drugs are effective for diabetic macular edema new trial shows

Science Daily - Thu, 19/02/2015 - 4:56pm
In the first clinical trial directly comparing three drugs most commonly used to treat diabetic macular edema, researchers found all were effective in improving vision and preventing vision loss. However, one drug, aflibercept, provided greater improvement for people with more severe vision loss when treatment was initiated.

New Android Trojan Fakes Device Shut Down, Spies On Users

Slashdot - Thu, 19/02/2015 - 4:31pm
An anonymous reader writes A new Android Trojan that tricks users into believing they have shut their device down while it continues working, and is able to silently make calls, send messages, take photos and perform many other tasks, has been discovered and analyzed by AVG researchers. They dubbed it, and AVG's security solutions detect it as PowerOffHijack.

Invasive weed Kochia's resistance to well-known herbicide stems from increase in gene copies

Science Daily - Thu, 19/02/2015 - 4:24pm
Kochia has evolved to have multiple copies of a gene code that targets glyphosate, the most common herbicide, a study has found. These copies enable the invasive weeds to survive the field rate of glyphosate applications.

Resistant Bacterial Infection Outbreak At California Hospital

Slashdot - Thu, 19/02/2015 - 3:51pm
puddingebola writes From the article: "A potentially deadly "superbug" resistant to antibiotics has infected seven patients, including two who died, and more than 160 others were exposed at Ronald Reagan UCLA Medical Center through contaminated medical instruments, the hospital revealed. The drug-resistant superbug known as CRE was likely transmitted to the Los Angeles patients by contaminated medical scopes during endoscopic procedures that took place between October 2014 and January 2015, a university statement said. " UCLA says the infections occurred via contaminated endoscopes that were sterilized according to the manufacturer's specifications.
