First species of yeti crab from hydrothermal vent systems near Antarctica described

Wed, 24/06/2015 - 6:31pm
The first species of yeti crab from hydrothermal vent systems of the East Scotia Ridge in the Southern Ocean, Antarctica, has been described. This Yeti Crab is famous for its body, which is densely covered by bristles -- known as setae -- and bacteria, giving it a fur-like appearance.

Targeting telomeres, the timekeepers of cells, could improve chemotherapy

Wed, 24/06/2015 - 6:02pm
Telomeres, specialized ends of our chromosomes that dictate how long cells can continue to duplicate themselves, have long been studied for their links to the aging process and cancer. In an unexpected finding, researchers show how disabling telomere protection during cell division prompts cell death.

Three Ebola virus variants identified in Guinea

Wed, 24/06/2015 - 6:02pm
Sequencing the genome of Ebola virus strains circulating in Guinea has allowed scientists to retrace the spread of the virus and monitor its evolution in the country where the outbreak started. Characterization of the genetic variations of the virus is crucial to ensure the continued efficacy of diagnostic tools and for the development of effective treatments and vaccines.

Newly found ring of teeth uncovers what common ancestor of molting animals looked like

Wed, 24/06/2015 - 6:02pm
A new analysis of one of the most bizarre-looking fossils ever discovered has definitively sorted its head from its tail, and turned up a previously unknown ring of teeth, which could help answer some of the questions around the early development of molting animals.

Color of urine to be valid gauge for hydration in children, researcher finds

Wed, 24/06/2015 - 6:01pm
More than half of American children are dehydrated, and a researcher has found an easy way for children to gauge hydration using established protocols already in place for athletes. The research also shows that children can accurately self-assess hydration levels using established methods. Mild dehydration in children has been linked to reduced cognitive functioning and is associated with poorer school performance in children.

Challenging negative stereotypes to narrow the achievement gap

Wed, 24/06/2015 - 5:26pm
A writing intervention linked to improved academic performance among girls and minorities may work by triggering a sense of belonging, helping to ease the students' anxiety, say researchers. They are the first to apply text-mining techniques to analyze the content of experimental essays showing that some students do better in school when asked to write about values important to them.

Diabetic blindness: Best source of stem cells to block vision loss

Wed, 24/06/2015 - 5:26pm
Stem cells taken from donors are more likely to be more effective at battling diabetic retinopathy than cells taken from patients' own bodies, a new study concludes. The work is a critical step toward the goal of injecting stem cells into patients' eyes to stop or even reverse the vision loss. The findings also establish a crucial framework for evaluating stem cells to be used in potential future treatments for diabetic retinopathy.

'Behemoth' bleeding atmosphere around a warm Neptune-sized exoplanet

Wed, 24/06/2015 - 5:24pm
Astronomers have discovered an immense cloud of hydrogen dispersing from a warm, Neptune-sized planet orbiting a nearby star. The enormous comet-like tail of the planet is about 50 times the size of the parent star.

Tiny particles in blood useful for early diagnosis of pancreatic cancer

Wed, 24/06/2015 - 5:24pm
A protein encoded by the gene glypican-1 (GPC1) present on cancer exosomes may be used as part of a potential non-invasive diagnostic and screening tool to detect early pancreatic cancer, potentially at a stage amenable to surgical treatment, according to a new study.

What's new in contact lenses? Prescribing trends reflect new lens materials, designs

Wed, 24/06/2015 - 3:56pm
More Americans are using soft contact lenses—especially daily disposable lenses—and taking advantage of new designs targeting vision problems that were difficult to correct with previous contact lenses, reports a new article.

Geography is destiny in deaths from kidney failure, study shows

Wed, 24/06/2015 - 3:56pm
The notion that geography often shapes economic and political destiny has long informed the work of economists and political scholars. Now a study led by medical scientists reveals how geography also appears to affect the very survival of people with end-stage kidney disease in need of dialysis.

Reenergizing antibiotics in the war against infections

Wed, 24/06/2015 - 3:54pm
In principle, antibiotics suppress infections either by killing the bacteria, which is called a bactericidal effect or by merely inhibiting their growth, by what is called a bacteriostatic effect. After the treatment has been stopped, growth-inhibited bacteria, however, can re-emerge from their dormancy to start multiplying again with latent infections relapsing back into full-blown attacks. A critical differentiator that separates the effects of bactericidal and bacteriostatic antibiotics has been identified by researchers: cellular respiration.

How the brightest lights in the universe 'flicker'

Wed, 24/06/2015 - 3:54pm
Active galactic nuclei are the brightest objects in the universe. They are not lit up permanently, but rather 'flicker' extremely slowly. This insight helps researchers better understand the influence these nuclei and black holes have on their host galaxy.

Future physicians more inclined to embrace genomic medicine than practicing physicians

Wed, 24/06/2015 - 3:54pm
Medical students showed a greater acceptance of using approaches in genomic medicine, a key element in the practice of precision medicine, to treat patients as compared to physicians currently in practice according to a study.

Study examines Cesarean section delivery, autism spectrum disorder

Wed, 24/06/2015 - 3:54pm
The initial results of a study suggested that children born by Cesarean section were 21 percent more likely to be diagnosed with autism spectrum disorder but that association did not hold up in further analysis of sibling pairs, implying the initial association was not causal and was more likely due to unknown genetic or environmental factors.
