Combining different malaria vaccines could reduce cases by 91 percent

EurekAlert! - Lun, 06/18/2018 - 22:00
Using two experimental anti-malarial vaccines, which work in different ways, can greatly reduce the number of malaria infections in animal studies.

Twenty-five per cent of seafood sold in Metro Vancouver is mislabelled

EurekAlert! - Lun, 06/18/2018 - 22:00
A new UBC study used DNA barcoding to determine that 70 of 281 seafood samples collected in Metro Vancouver between September 2017 and February 2018 were mislabelled.

Children's immune system could hold the key to preventing sepsis

EurekAlert! - Lun, 06/18/2018 - 22:00
Scientists have identified the key response that children use to control infections.

Opioid dependence in patients with degenerative spondylolisthesis: More likely to occur before than after surgery

EurekAlert! - Lun, 06/18/2018 - 22:00
Researchers investigated risk factors for the development of opioid dependence in patients undergoing surgery for degenerative spondylolisthesis (DS). They found that, overall, patients were more likely to have a dependency on opioid medications before surgery than afterward.

Good relationships with siblings may buffer the effects of family conflict

EurekAlert! - Lun, 06/18/2018 - 22:00
A new longitudinal study finds that having a good relationship with a sibling may help buffer the distress of ongoing hostility between parents.

Parents' explanations of peer interactions affect how children interpret peers' behavior

EurekAlert! - Lun, 06/18/2018 - 22:00
New research in the journal Child Development shows that parents can help their children perceive less hostility in their social world by framing social situations in a positive way, and thus, reduce their likelihood of behaving aggressively.

RFK's assassination: A medical analysis of his injuries and neurosurgical care

EurekAlert! - Lun, 06/18/2018 - 22:00
Covers the assassination of Robert F. Kennedy. The authors 'review the eyewitness reports of the mechanism of injury, the care rendered for three hours prior to the emergency craniotomy, the clinical course, and, ultimately, the autopsy.' The discussion of autopsy findings is supplemented by an artist's depiction of the extent of Senator Kennedy's head injury.

Everything big data claims to know about you could be wrong

EurekAlert! - Dom, 06/17/2018 - 22:00
When it comes to understanding what makes people tick -- and get sick -- medical science has long assumed that the bigger the sample of human subjects, the better. But new research led by the University of California, Berkeley, suggests this big-data approach may be wildly off the mark.

Scripps graduate student discovers world's first known manta ray nursery

EurekAlert! - Dom, 06/17/2018 - 22:00
A graduate student at Scripps Institution of Oceanography at the University of California San Diego and colleagues from NOAA's Office of National Marine Sanctuaries have discovered the world's first known manta ray nursery.

Blue gene regulation helps plants respond properly to light

EurekAlert! - Dom, 06/17/2018 - 22:00
Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) have discovered a process through which gene expression in plants is regulated by light. Published in Proceedings of the National Academy of Sciences USA, the study found that blue light triggers a shift in which portion of a gene is ultimately expressed.

Bees love blue fluorescent light, and not just any wavelength will do

EurekAlert! - Dom, 06/17/2018 - 22:00
Researchers have learned that a specific wavelength range of blue fluorescent light set bees abuzz.

First delivery episiotomies may require repeat procedures -- Ben-Gurion U. researchers

EurekAlert! - Dom, 06/17/2018 - 22:00
After studying more than 43,000 deliveries at Soroka over 24 years (1991-2015), researchers found that 17.5 percent of mothers who had an episiotomy during their first delivery required repeat procedures, while only 3.1 percent of those who did not have an episiotomy the first time required one.

Study finds reduction in sulfur emissions from power plants in China

EurekAlert! - Dom, 06/17/2018 - 22:00
Air pollution has smothered China's cities in recent decades. In response, the Chinese government has implemented measures to clean up its skies. But are those policies effective? Now an innovative study co-authored by an MIT scholar shows that one of China's key antipollution laws is indeed working -- but unevenly, with one particular set of polluters most readily adapting to it.

BPA can induce multigenerational effects on ability to communicate

EurekAlert! - Dom, 06/17/2018 - 22:00
Past studies have shown that biparental care of offspring can be affected negatively when females and males are exposed to bisphenol A (BPA. In a study published today in the journal PLOS One, researchers at the University of Missouri found that mice pups whose grandparents had been exposed to BPA, had different vocalization patterns. This, in turn, could also affect the amount of parental care they received. Scientists believe results could have important relevance to humans.

Why being left-handed matters for mental health treatment

EurekAlert! - Dom, 06/17/2018 - 22:00
Treatment for the most common mental health problems could be ineffective or even detrimental to about 50 percent of the population, according to a radical new model of emotion in the brain.

Princeton scientists uncover a factor important for ZIKA Virus host species restriction

EurekAlert! - Dom, 06/17/2018 - 22:00
In 2013 and 2015, devastating outbreaks of ZIKA captured world attention. The virus is often transmitted from wild animals -- probably non-human primates -- via mosquitos to humans. This is the first comprehensive study to investigate which mammal species may host the ZIKA virus (ZIKV). 'We systematically tested the ability of ZIKV to infect cells from humans, great apes, New World and Old World monkeys, and mice,' explained Princeton Professor Alexander Ploss.

'Artificial blubber' protects divers in frigid water

EurekAlert! - Dom, 06/17/2018 - 22:00
A treatment that infuses a conventional neoprene wetsuit with a heavy inert gas can improve a diver's survival time in frigid waters by a factor of three, according to scientists and others.

Often overlooked glial cell is key to learning and memory

EurekAlert! - Dom, 06/17/2018 - 22:00
Glial cells surround neurons and provide support -- not unlike hospital staff and nurses supporting doctors to keep operations running smoothly. These often-overlooked cells, which include oligodendrocytes and astrocytes, are the most abundant cell types in the central nervous system. But these cells do more than support neurons. They also actively influence them, University of California, Riverside, researchers report.

Methadone and buprenorphine decrease mortality after nonfatal overdose

EurekAlert! - Dom, 06/17/2018 - 22:00
new study out of Boston Medical Center's Grayken Center for Addiction on opioid overdose survivors indicates that two FDA approved medications to treat opioid use disorder save lives, but only three out of 10 overdose survivors receive them.

Coral reef 'oases' offer glimmer of hope

EurekAlert! - Dom, 06/17/2018 - 22:00
An international team of scientists have discovered small communities of corals that are flourishing against the odds while so many around the world are dying.
