Britain on brink of freshwater species 'invasion' from south east Europe

13/10/2014 | CIENCIA ON LINE
New research shows multiple invasive species with the same origin facilitate each other's ability to colonize ecosystems. By studying how these species interact as well as current population locations, researchers believe that Britain is heading for an 'invasion meltdown' of freshwater species from...

Body contouring after bariatric surgery helps obese patients keep weight off

11/10/2014 | CIENCIA ON LINE
Patients who have plastic surgery to reshape their bodies after bariatric procedures are able to maintain 'significantly greater' weight loss than those who do not have surgery, according to a new study. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/D...

Oral capsule as effective as invasive procedures for delivery of fecal transplant

11/10/2014 | CIENCIA ON LINE
A noninvasive method of delivering a promising therapy for persistent Clostridium difficile infection appears to be as effective as treatment via colonoscopy or through a nasogastric tube. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/B...

Common anesthetic procedure dramatically improves well being of veterans with PTSD

11/10/2014 | CIENCIA ON LINE
A single application of a common anesthetic procedure could be the answer to alleviating anxiety, depression and psychological pain in those suffering from chronic, extreme post-traumatic stress disorder (PTSD), according to research. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/O...

Helping Japanese fishermen fight off crown-of-thorns starfish

11/10/2014 | CIENCIA ON LINE
The long term population dynamics of the Crown-of-Thorns starfish, Acanthaster planci, has been the focus of recent study. This is one of the most long term and extensive surveys of its kind, with data spanning over 24 years through cooperation with the Japanese fishing population of Onna Village...

Interactive history beats interactive chat for website engagement

10/10/2014 | CIENCIA ON LINE
Small cues that display a user's transaction history may help a website feel almost as interactive as chatting with an online customer service agent, paving the way for more cost-effective websites, according to researchers. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/r...

No single explanation for biodiversity in Madagascar

10/10/2014 | CIENCIA ON LINE
No single 'one-size-fits-all' model can explain how biodiversity hotspots come to be, finds a study of more than 700 species of reptiles and amphibians in Madagascar. By analyzing the distribution of Madagascar's lizards, snakes, frogs and tortoises, researchers find that each group responded...

Getting sharp images from dull detectors

10/10/2014 | CIENCIA ON LINE
Observing the quantum behavior of light is a big part of Alan Migdall's research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons -- the particle complement of light waves -- and sometimes only one photon at a time, using "smart" detectors...

Pneumococcal vaccine reduces antibiotic-resistant infections in children by 62 percent

10/10/2014 | CIENCIA ON LINE
The pneumococcal vaccine recommended for young children not only prevents illness and death, but also has dramatically reduced severe antibiotic-resistant infections, suggests American nationwide research. Pneumococcal infection -- which can cause everything from ear infections to pneumonia and...

Insisting only on randomised controlled trials for Ebola treatments unethical, impractical, say leading health experts

10/10/2014 | CIENCIA ON LINE
Leading health experts urge the deployment of alternative trial designs to fast-track the evaluation of new Ebola treatments. Senior health professionals and medical ethicists, from Africa, Europe, and USA, argue that although randomized controlled trials (RCTs) provide robust evidence in most...

Antiretroviral therapy benefits HIV-infected stimulant users

10/10/2014 | CIENCIA ON LINE
341 HIV-infected men who reported using stimulants such as methamphetamine or cocaine derived life-saving benefits from being on antiretroviral therapy that were comparable to those of HIV-infected men who do not use stimulants, a study concludes. Fuente :...

Demand high for engineers in midwest

10/10/2014 | CIENCIA ON LINE
Engineering students preparing to take their sheepskin and depart into the world of change orders and service requests are finding no shortage of companies wanting to take their resumes. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/t...

Mineralization of sand particles boosts microbial water filtration

10/10/2014 | CIENCIA ON LINE
Mineral coatings on sand particles actually encourage microbial activity in the rapid sand filters that are used to treat groundwater for drinking, according to a paper. These findings resoundingly refute, for the first time, the conventional wisdom that the mineral deposits interfere with...

College athletes in contact sports more likely to carry MRSA, study finds

09/10/2014 | CIENCIA ON LINE
Even if they don't show signs of infection, college athletes who play football, soccer and other contact sports are more likely to carry the superbug methicillin-resistant Staphylococcus aureus. This puts them at higher risk for infection and increases the likelihood of spreading the bug, which...

Effect of antibiotic susceptibility for patients with bloodstream infection

09/10/2014 | CIENCIA ON LINE
In an analysis of more than 8,000 episodes of Staphylococcus aureus bloodstream infections, there were no significant differences in the risk of death when comparing patients exhibiting less susceptibility to the antibiotic vancomycin to patients with more vancomycin susceptible strains of S....

Discovery of new subatomic particle, type of meson, to 'transform' understanding of fundamental force of nature

09/10/2014 | CIENCIA ON LINE
The discovery of a new particle will "transform our understanding" of the fundamental force of nature that binds the nuclei of atoms, researchers argue. The discovery of the new particle will help provide greater understanding of the strong interaction, the fundamental force of nature found...

Drinking decaf or regular coffee maybe good for the liver

09/10/2014 | CIENCIA ON LINE
Researchers report that decaffeinated coffee drinking may benefit liver health. Results show that higher coffee consumption, regardless of caffeine content, was linked to lower levels of abnormal liver enzymes. This suggests that chemical compounds in coffee other than caffeine may help protect...

Cellular 'power grid' failure triggers abnormal heart rhythms after a heart attack

09/10/2014 | CIENCIA ON LINE
Heart attack survivors often experience dangerous heart rhythm disturbances during treatment designed to restore blood flow to the injured heart muscle, a common and confounding complication of an otherwise lifesaving intervention. Now researchers working with rat heart cells have shown that such...

Impossibly bright dead star: X-ray source in the Cigar Galaxy is the first ultraluminous pulsar ever detected

08/10/2014 | CIENCIA ON LINE
Astronomers working with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) have found a pulsating dead star beaming with the energy of about 10 million suns. The object, previously thought to be a black hole because it is so powerful, is in fact a pulsar -- the incredibly dense rotating...

Making sure antibiotics work as they should

08/10/2014 | CIENCIA ON LINE
Researchers are decoding the structure of the large ribosomal subunit of the mitochondria at an atomic level, thereby providing insight into the molecular architecture of this ribosome with implications for a better understanding of the mode of action of antibiotics. Fuente :...
