Predicting which stroke patients will be helped -- or harmed -- by clot-busting treatment
2014-05-19
Johns Hopkins researchers say they have developed a technique that can predict — with 95 percent accuracy — which stroke victims will benefit from intravenous, clot-busting drugs and which will suffer dangerous and potentially lethal bleeding in the brain.
Reporting online May 15 in the journal Stroke, the Johns Hopkins team says these predictions were made possible by applying a new method they developed that uses standard magnetic resonance imaging (MRI) scans to measures damage to the blood-brain barrier that protects the brain from drug exposure.

2014-05-19
RIVERSIDE, Calif. — Cabo Pulmo is a close-knit community in Baja California Sur, Mexico, and the best preserved coral reef in the Gulf of California. But now the lands adjacent to the reef are under threat from a mega-development project, "Cabo Dorado," should construction go ahead.
Scientists at the University of California, Riverside have published a report on the terrestrial biodiversity of the Cabo Pulmo region that shows the project is situated in an area of extreme conservation value, the center of which is Punta Arena, an idyllic beach setting proposed to be completely ...
Different types of El Nino have different effects on global temperature
2014-05-19
The El Niño–Southern Oscillation is known to influence global surface temperatures, with El Niño conditions leading to warmer temperatures and La Niña conditions leading to colder temperatures. However, a new study in Geophysical Research Letters shows that some types of El Niño do not have this effect, a finding that could explain recent decade-scale slowdowns in global warming.
The authors examine three historical temperature data sets and classify past El Niño events as traditional or central Pacific. They find that global surface temperatures were anomalously warm ...
Does birth control impact women's choice of sexual partners?
2014-05-19
Birth control is used worldwide by more than 60 million women. Since its introduction, it has changed certain aspects of women's lives including family roles, gender roles and social life. New research in The Journal of Sexual Medicine found a link between birth control and women's preferences for psychophysical traits in a sexual mate.
The researchers utilized a PMI (Partner's Masculinity Index) to determine the male traits that women found attractive during the fertile phase of their menstrual cycle. The participants were from Central Italy and divided into two groups ...
Teens who participate in sports show lower levels of hazardous drinking
2014-05-19
New research in Criminal Behavior and Mental Health aimed to find the relationship between participation in organized sports and an increase in hazardous drinking. Unlike previous research, the study focused on an underrepresented group – young offenders – adolescents who were either excluded from school or involved with the justice system.
93 British male young offenders from a local Youth Offending Team participated in the study, as well as 53 non-offenders from local schools. Both groups had similarly low socioeconomic status. Participants were asked to partake in ...
Citizen scientists map the flyways of North American birds
2014-05-19
Flyways used by migratory birds as they travel across America have long been a topic of fascination for ornithologists. For larger species like waterfowl that are easily visible during their migratory flights, these flyways have been described, but until now the flyways for smaller-bodied birds have been largely based on conjecture.
New research in the Journal of Biogeography has used analyses of information from the eBird citizen-science database to describe week by week the distributions of 93 North American land birds. By determining the level of similarity in the ...
Wildfires around Lake Baikal, Russia
2014-05-19
Lake Baikal, which is usually still frozen over at this time of year, can clearly be seen in the image. At this time, though, the lake has lost all of its ice coverage already even though snow still surrounds it. Temperatures in this region have skyrocketed in the past few weeks to the 70s prompting outbreaks of fires. Temperatures are usually cooler until late July/early August when the bulk of the wildfires in this area normally erupt. Careless handling with fire and withered dry grass fires on the croplands reportedly were the main reasons for the fires.

Several new apple varieties recommended for growers
2014-05-19
PARMA, ID – 'Fuji' apples have become increasingly popular among consumers, but the apple variety faces some challenges on its path to full consumer appreciation. Research has determined that "consumer acceptance" of apples depends largely on fruit color, size, eating quality, and texture. Consumers are very discerning: poor color can drastically reduce the value of red apples, even if their size is acceptable. The poor and inconsistent peel color of 'Fuji' apple strains has limited the apple's marketability. The authors of a new study say that the introduction of new 'Fuji' ...
Making better medicines with a handful of chemical building blocks
2014-05-19

Children who exercise have better body-fat distribution, regardless of their weight
2014-05-19
URBANA, Ill. – Maybe the numbers on the scale aren't alarming, but that doesn't mean that healthy-weight children get a pass on exercising, according to a new University of Illinois study published in Pediatrics.
"The FITKids study demonstrates the extent to which physical activity can improve body composition, and that's important because it matters to your health where fat is stored. But the study is also interesting for what happened in the control group to the kids who didn't exercise," said Naiman Khan, a postdoctoral researcher in the U of I's Division of Nutritional ...
New 'T-ray' tech converts light to sound for weapons detection, medical imaging
2014-05-19
ANN ARBOR—A device that essentially listens for light waves could help open up the last frontier of the electromagnetic spectrum—the terahertz range.
So-called T-rays, which are light waves too long for human eyes to see, could help airport security guards find chemical and other weapons. They might let doctors image body tissues with less damage to healthy areas. And they could give astronomers new tools to study planets in other solar systems. Those are just a few possible applications.
But because terahertz frequencies fall between the capabilities of the specialized ...

Researchers at Teesside University in the U.K. investigated how combining cognitive activities and elements of yoga, tai chi, qigong and meditation with routine physical exercise affected dementia patients. They found that a holistic exercise program focusing on both mind and body can help improve quality of life for dementia patients. Their findings are ...
Optical brain scanner goes where other brain scanners can't
2014-05-19
Scientists have advanced a brain-scanning technology that tracks what the brain is doing by shining dozens of tiny LED lights on the head. This new generation of neuroimaging compares favorably to other approaches but avoids the radiation exposure and bulky magnets the others require, according to new research at Washington University School of Medicine in St. Louis.
The new optical approach to brain scanning is ideally suited for children and for patients with electronic implants, such as pacemakers, cochlear implants and deep brain stimulators (used to treat Parkinson's ...

Liberating devices from their power cords
2014-05-19
Imagine a future in which our electrical gadgets are no longer limited by plugs and external power sources.
This intriguing prospect is one of the reasons for the current interest in building the capacity to store electrical energy directly into a wide range of products, such as a laptop whose casing serves as its battery, or an electric car powered by energy stored in its chassis, or a home where the dry wall and siding store the electricity that runs the lights and appliances.
It also makes the small, dull grey wafers that graduate student Andrew Westover and Assistant ...
Having and raising offspring is costly phase of life for baboon moms
2014-05-19
Observations made over the past 29 years in Kenya as part of one of the world's longest-running studies of a wild primate show how having offspring influences the health of female baboons. These observations highlight that females are mostly injured on days when they are likely to conceive. In addition, injuries heal the slowest when they are suckling their young. The study, published in Springer's journal Behavioral Ecology and Sociobiology, is led by Elizabeth Archie of the University of Notre Dame in the US and the National Museums of Kenya.

Genes play key role in brain injury risk for premature babies
2014-05-19
Premature babies' risk of brain injury is influenced by their genes, a new study suggests.
Researchers have identified a link between injury to the developing brain and common variation in genes associated with schizophrenia and the metabolism of fat.
The study builds on previous research, which has shown that being born prematurely – before 37 weeks – is a leading cause of learning and behavioural difficulties in childhood.
Around half of infants weighing less than 1500g at birth go on to experience difficulties in learning and attention at school age.

Engineers find way to lower risk of midair collisions for small aircraft
2014-05-19
Researchers at North Carolina State University have developed new modifications for technology that helps pilots of small aircraft avoid midair collisions. The modified tools significantly improved pilot response times in making decisions to avert crashes.
At issue are "cockpit displays of traffic information" (CDTIs). These are GPS displays used by private pilots to track other aircraft in their vicinity. However, pilots often focus on the closest aircraft on the display – a habit that can pose a significant hazard.
If the pilot of Plane A sees two planes on the CDTI, ...
How octopuses don't tie themselves in knots revealed by Hebrew University scientists
2014-05-19
An octopus's arms are covered in hundreds of suckers that will stick to just about anything, with one important exception: those suckers generally won't grab onto the octopus itself, otherwise the impressively flexible animals would quickly find themselves all tangled up.
Now, researchers from the Hebrew University of Jerusalem report that they discovered how octopuses manage this feat, even as the creatures' brains are unaware of what their arms are doing. A chemical produced by octopus skin temporarily prevents their suckers from sucking.
"We were surprised that ...
