Glowing corals that display a surprising array of colours have been discovered in the deep water reefs of the Red Sea by scientists from the University of Southampton, UK, Tel Aviv University and the Interuniversity Institute for Marine Sciences (IUI), Israel, together with an international team of researchers.
The researchers, whose findings have been published online today in research journal PLOS ONE, hope that some of the coral pigments could be developed into new imaging tools for medical applications.
The team studied corals at depths of more than 50 metres and ...
Got acne? Lay off the B12
2015-06-24
Vitamin B12 tweaks how genes behave in the facial bacteria of some people who normally enjoy clear skin. The activity changes of the facial bacteria promote inflammation and lead to pimples.
By shedding light on one mechanism behind B12's role in acne, the UCLA finding may identify drug targets that lead to new treatments for acne.
Huiying Li, an assistant professor of molecular and medical pharmacology at the David Geffen School of Medicine at UCLA, and Dr. Noah Craft, a dermatologist at LA BioMed at Harbor-UCLA Medical Center, are available for interviews.

Scientists highlight the importance of nanoscale hybrid materials for noninvasive cancer diagnosis
2015-06-24
Various diagnostic imaging techniques are currently used for clinical imaging/disease diagnosis. The accuracy of diagnosis is mainly based on the type of energy used (such as X-ray, sound waves, photons and positrons) to derive the visual information, as well as the degree of spatial resolution (mesoscopic or microscopic) and the level of information that can be obtained (physiological, anatomical or molecular). Based on potential health hazards imposed by type of energy used, clinical imaging modalities can be broadly categorized as ionizing and non-ionizing modalities. ...
This week from AGU: Malaysian quake aftermath, Arctic sea ice predictions

From AGU's blogs: Landslide-induced sediment production after the Sabah earthquake in Malaysia
The Mw=6.0 5 June 2015 Sabah earthquake in Malaysia, which killed 18 people in rockfalls on Mount Kinabalu, generated landslides that have released large volumes of sediment. The heavy tropical rainfall in Sabah means that this sediment is now starting to enter the river systems in the form of mudflows and sediment-rich flash floods. Dave Petley explores the aftermath of the Sabah earthquake in a new post on The Landslide Blog.

Newly found ring of teeth uncovers what common ancestor of molting animals looked like
2015-06-24
A new study of an otherworldly creature from half a billion years ago - a worm-like animal with legs, spikes and a head difficult to distinguish from its tail - has definitively identified its head for the first time, and revealed a previously unknown ring of teeth and a pair of simple eyes. The results, published today in the journal Nature, have helped scientists reconstruct what the common ancestor of everything from tiny roundworms to huge lobsters might have looked like.
Researchers from the University of Cambridge, the Royal Ontario Museum and the University of ...
Targeting telomeres, the timekeepers of cells, could improve chemotherapy
2015-06-24
LA JOLLA--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. Now, a discovery at the Salk Institute shows that telomeres may be more central than previously thought to a self-destruct program in cells that prevents tumors, a function that could potentially be exploited to improve cancer therapies.
When cells replicate in a process called mitosis, their telomeres get a little shorter each time. Eventually, after many cell divisions, telomeres ...
Giant comet-like tail discovered on small exoplanet
2015-06-24
The prospect of finding ocean-bearing exoplanets has been boosted, thanks to a pioneering new study.
An international team of scientists, including from the University of Exeter, has discovered an immense cloud of hydrogen escaping from a Neptune-sized exoplanet.
Such a phenomena not only helps explain the formation of hot and rocky 'super-earths', but also may potentially act as a signal for detecting extrasolar oceans. Scientists also believe they can use the discovery to envisage the future of Earth's atmosphere, four billion years from today.
The ground-breaking ...

Study examines cesarean section delivery and autism spectrum disorder
2015-06-24
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, according to an article published online by JAMA Psychiatry.
Autism spectrum disorder (ASD) is thought to affect about 0.62 percent of children worldwide, although estimates in the United States have been closer to 1.5 percent. ...
Geography is destiny in deaths from kidney failure, study shows
2015-06-24
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 at Johns Hopkins reveals how geography also appears to affect the very survival of people with end-stage kidney disease in need of dialysis.
"If you are a person with kidney failure in Texas you're in trouble, but if you're in New England you're golden, and that's profoundly troubling because the quality of care shouldn't be predicated on your ZIP code," says senior investigator Mahmoud Malas, M.D., ...
Reenergizing antibiotics in the war against infections
2015-06-24
(BOSTON) - Antibiotics are the mainstay in the treatment of bacterial infections, and together with vaccines, have enabled the near eradication of infectious diseases like tuberculosis, at least in developed countries. However, the overuse of antibiotics has also led to an alarming rise in resistant bacteria that can outsmart antibiotics using different mechanisms. Some pathogenic bacteria are thus becoming almost untreatable, not only in underdeveloped countries but also in modern hospital settings.
While some researchers seek to develop antibiotics with new mechanisms ...
Girls suffer more overuse injuries in teen sports
2015-06-24
COLUMBUS, Ohio - A new study performed by researchers at The Ohio State University Wexner Medical Center shows that when it comes to overuse injuries in high school sports, girls are at a much higher risk than boys. Overuse injuries include stress fractures, tendonitis and joint pain, and occur when athletes are required to perform the same motion repeatedly.
The study published in April in the Journal of Pediatrics. Dr. Thomas Best analyzed 3,000 male and female injury cases over a seven year period across 20 high school sports such as soccer, volleyball, gymnastics ...
What your clothes may say about you
2015-06-24
PITTSBURGH, June 24 -- Moving closer to the possibility of "materials that compute" and wearing your computer on your sleeve, researchers at the University of Pittsburgh Swanson School of Engineering have designed a responsive hybrid material that is fueled by an oscillatory chemical reaction and can perform computations based on changes in the environment or movement, and potentially even respond to human vital signs. The material system is sufficiently small and flexible that it could ultimately be integrated into a fabric or introduced as an inset into a shoe.

EARTH: Studies re-examine how major copper deposits form
2015-06-24
Alexandria, VA - Humans depend on copper for everything from electrical wiring to water pipes. To meet demand, the metal has been largely mined from Porphyry Copper Deposits (PCDs). For decades, scientists generally agreed upon the geological processes behind PCD formation; now EARTH Magazine examines two new studies that suggest alternatives to these long-held understandings.
From enriched pulses of magmatic fluids creating copper concentrations, to remelted crust allowing deeper PCDs to rise up to shallower depths, these conclusions may better inform geologists about ...
Partnering of PD researchers with patient groups needed to improve effectiveness of clinical trials
2015-06-24
Amsterdam, NL, June 24, 2015 - Despite an urgent need for new medications, clinical trials in Parkinson's disease (PD) have a relatively low rate of success. The reasons for this are complex, prompting a group of investigators from PD advocacy groups to conduct a survey of the principle stakeholders, PD scientists, patients, and caregivers, to determine some of the underlying barriers. Their results are published in the Journal of Parkinson's Disease.
"With development of a new drug estimated to cost between $1 and $3 billion and taking as long as 15 years, the successful ...
Not drink driving is often against the lore: QUT study
2015-06-24
Cultural "lore" outweighs criminal law when Indigenous drivers in regional and remote communities get behind the wheel drunk, a new study by Queensland University of Technology has found.
Michelle Fitts, from QUT's Centre for Accident Research & Road Safety-Queensland (CARRS-Q), said the decision to drink drive was not necessarily made in disregard for criminal law but rather to meet cultural obligations.
As part of her Ph.D., Fitts explored the motivations that influence Indigenous people to drink drive in regional and remote communities through one-on-one interviews ...
Distributed technique for power 'scheduling' advances smart grid concept
2015-06-24
Researchers from North Carolina State University have developed a new technique for "scheduling" energy in electric grids that moves away from centralized management by tapping into the distributed computing power of energy devices. The approach advances the smart grid concept by coordinating the energy being produced and stored by both conventional and renewable sources.
Currently, power infrastructure uses a centralized scheduling approach to forecast and coordinate the energy produced at the thousands of large power plants around the country. But as renewable energy ...
New Zealand blackcurrants good for the brain
2015-06-24
Research has shown that New Zealand blackcurrants are good for keeping us mentally young and agile, a finding that could have potential in managing the mental decline associated with aging populations, or helping people with brain disorders such as Parkinson's disease or depression.
The research, conducted by scientists at Plant & Food Research (New Zealand) in collaboration with Northumbria University (UK), showed that compounds found in New Zealand blackcurrants increased mental performance indicators, such as accuracy, attention and mood. The study also showed that ...
Minorities underrepresented in US special education classrooms
2015-06-24
Although minority children are frequently reported to be overrepresented in special education classrooms, a team of researchers suggests that minority children are less likely than otherwise similar white children to receive help for disabilities.
The previously reported overrepresentation is most likely due to a greater exposure to environmental and economic risk factors, said Paul Morgan, associate professor of education, Penn State.
"The general limitation of the available studies is that they haven't been able to correct for minority children's unfortunate, but ...
Artifical neuron mimicks function of human cells
2015-06-24
Scientists at Sweden's Karolinska Institutet have managed to build a fully functional neuron by using organic bioelectronics. This artificial neuron contain no "living" parts, but is capable of mimicking the function of a human nerve cell and communicate in the same way as our own neurons do.
Neurons are isolated from each other and communicate with the help of chemical signals, commonly called neurotransmitters or signal substances. Inside a neuron, these chemical signals are converted to an electrical action potential, which travels along the axon of the neuron until ...
Study identifies characteristics of patients likely to have a potential living liver donor
2015-06-24
New research published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, reports that younger patients, those who are married, and those with Child-Pugh C disease--the most severe measure of liver disease--are more likely immigrants, divorced patients and those at the lowest income levels were less likely to have a potential live donor volunteer for liver donation.
With a limited supply of deceased donor organs, livers from living donors provide a much needed, life-saving ...
Oh, to have Dr. Facebook on call!
2015-06-24
If it were up to Internet-savvy Americans, more of them would be emailing or sending Facebook messages to their doctors to chat about their health. That's the result of a national survey led by Joy Lee of Johns Hopkins Bloomberg School of Public Health in the US. The findings¹ appear in the Journal of General Internal Medicine², published by Springer.
Surveys were sent to more than 4,500 customers of a retail pharmacy. The replies of the 2,252 respondents were included in the analysis. Respondents tended to be well educated, in good health, and frequent users ...
