Scientists have shown how the brain anticipates all of the new situations that it may encounter in a lifetime by creating a special kind of neural network that is 'pre-adapted' to face any eventuality.

New treatment offers hope for children with debilitating skin and muscle disease

Posted: 10 Jun 2016 11:08 AM PDT

The results of a UK study showed that tumor necrosis factor inhibitor treatment is effective at improving both muscle and skin involvement in children with juvenile dermatomyositis (JDM). These findings bring new hope to JDM patients who have failed to respond to multiple drug treatments and who, as a result, have a greater risk of painful complications and premature death.

Facebook key to identifying thousands with inflammatory back pain

Posted: 10 Jun 2016 11:07 AM PDT

The results of a UK study showed that using Facebook to raise awareness about the symptoms of Inflammatory Back Pain (IBP) and the need to seek medical help early may reduce the delay in diagnosis and treatment. The findings suggest that Facebook advertising may be a more effective way of identifying IBP patients earlier than other approaches, including newspaper adverts.

Southern Europe risks Zika outbreaks this summer

Posted: 10 Jun 2016 08:27 AM PDT

Established Aedes-mosquito population could spread the Zika virus in Europe this summer if infected travelers introduce the virus. An analysis of temperatures, vectorial capacity, basic reproductive number (R0), and air traveler flows suggests parts of Southern Europe may be at risk for Zika outbreaks between June and August, according to a study.

Scientists have discovered a unique pattern of scarring in the brains of deceased service members who were exposed to blast injury that differs from those exposed to other types of head injury.

The vascular bypass revolution

Posted: 10 Jun 2016 06:52 AM PDT

Coronary or peripheral bypasses are the most frequently performed vascular operations. Although one million patients per year and around the world, undergo this intervention, its failure rate reaches 50%, because of poor vessel healing, leading to vessel graft occlusion. To improve the outcome of bypasses, researchers have developed a gel containing microparticles –'GeM', enabling the controlled release of a drug inhibiting cellular over-proliferation. Administered locally, directly on the bypass graft during surgery, this preventive treatment will reduce the risk of obstruction reoccurrence.

Pill may increase survival after colon cancer

Posted: 10 Jun 2016 06:50 AM PDT

It is well known that the drug ASA, also known internationally as Aspirin, has analgesic and fever-reducing properties. However, this drug may also increase the likelihood of surviving colon cancer.

Popcorn-like fossils provide evidence of environmental impacts on species numbers

Posted: 10 Jun 2016 06:50 AM PDT

The number of species that can exist on Earth depends on how the environment changes, according to new research By analyzing the fossil record of microscopic aquatic creatures called planktonic foraminifera, whose fossil remains now resemble miniaturized popcorn and date back millions of years, the research provided the first statistical evidence that environmental changes put a cap on species richness.

Bifocals in the brain

Posted: 10 Jun 2016 06:50 AM PDT

Seeing -- arguably our most important way of perceiving the world -- mostly happens without conscious intent. We see much better in the center of our visual field (along the visual axis) than in the periphery. So when our brain detects an object of interest in the periphery of our visual field, it immediately initiates an eye movement so our visual axis intersects with those objects. Once an object is in our direct line of sight, we can perceive it in far more depth and detail. Now researchers report that visual information from near and far space are processed with differing degrees of acuity.

Filarial nematodes taking a fancy to Austria

Posted: 10 Jun 2016 06:49 AM PDT

In Austria, the parasitic roundworms Dirofilaria repens and Dirofilaria immitis are usually considered to be unpleasant souvenirs from travels abroad. A preliminary study has identified indigenous mosquitoes as carriers of Dirofilaria repens, suggesting for the first time that the parasite has become endemic in Eastern Austria. Dirofilaria immitis, commonly known as heartworm, also appears to be on the verge of becoming autochthonous. The slow pace at which the parasites are establishing themselves is probably due in part to the keeping conditions of dogs in Austria.

A child’s right to fertility preservation when undergoing sterilizing chemotherapy

Posted: 10 Jun 2016 06:49 AM PDT

Ovarian tissue cryopreservation (OTC), harvesting and freezing ovarian tissue, is the most promising complication-free strategy to preserve potential fertility in pre-pubescent girls undergoing sterilizing chemotherapy, according to a 13 year study.

Individuals exposed to blue wavelength lights experienced faster reaction times

Posted: 10 Jun 2016 06:47 AM PDT

Disease that causes blindness in children tied to new gene

Posted: 10 Jun 2016 06:47 AM PDT

Scientists have identified a gene that causes severe glaucoma in children. The finding validates a similar discovery made by the scientists in mice two years ago and suggests a target for future therapies to treat the devastating eye disease that currently has no cure.

Average 'dead zone' predicted for Gulf of Mexico in 2016

Posted: 10 Jun 2016 06:47 AM PDT

Deep 'scars' from ancient geological events play role in current earthquakes

Posted: 10 Jun 2016 06:44 AM PDT

Super-computer modelling of Earth's crust and upper-mantle suggests that ancient geologic events may have left deep 'scars' that can come to life to play a role in earthquakes, mountain formation, and other ongoing processes on our planet. These multi-million-year-old structures, situated at sites away from existing plate boundaries, may trigger changes in the structure and properties at the surface in the interior regions of continents.

Laser ablation becomes increasingly viable treatment for prostate cancer

Posted: 10 Jun 2016 06:44 AM PDT

Up until now, capturing an image of a prostate cancer has been difficult because prostate tissue and tumor tissue are so similar. Precise, non-invasive surgical treatment has proved difficult as a result. Now researchers report that prostate cancer patients may soon have a new option to treat their disease: laser heat.

Disjointed: Cell differences may explain why rheumatoid arthritis varies by location

Posted: 10 Jun 2016 06:44 AM PDT

Not only are there distinct differences in key cellular processes and molecular signatures between rheumatoid arthritis (RA) and osteoarthritis (OA) but, more surprisingly, there are joint-specific differences in RA, report researchers. The findings help explain why drugs treating RA vary in effect and provide a potential new template for precisely targeting treatment for each and every ailing joint.

MS breakthrough: Replacing diseased immune system halts progression, allows repair

Posted: 09 Jun 2016 07:24 PM PDT

An intensive procedure that completely wipes out the immune system and then regenerates a new one using blood stem cells can eliminate all signs of damaging brain inflammation in people with early, aggressive multiple sclerosis (MS), and facilitate lasting recovery, report scientists.

Relationship advice from a gender-bending fish that mates for life

Posted: 09 Jun 2016 02:48 PM PDT

A 3-inch monogamous hermaphrodite proves the saying 'there's plenty more fish in the sea' isn't always the case. And researchers say said the loyal chalk bass offers humans in relationships this simple wisdom: You get what you give.

Climate change mitigation: Turning carbon dioxide into rock

Posted: 09 Jun 2016 11:24 AM PDT

An international team of scientists have found a potentially viable way to remove anthropogenic (caused or influenced by humans) carbon dioxide emissions from the atmosphere - turn it into rock. The study has shown for the first time that the greenhouse gas carbon dioxide can be permanently and rapidly locked away from the atmosphere, by injecting it into volcanic bedrock. The carbon dioxide reacts with the surrounding rock, forming environmentally benign minerals.
