The center of our galaxy is a frenzy of activity. A behemoth black hole -- 4 million times as massive as the sun -- blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and subsequently explode.
Now, an international team of astronomers has discovered two exhaust channels -- dubbed "galactic center chimneys" -- that appear to funnel matter and energy away from the cosmic fireworks in the Milky Way's center, about 28,000 light-years from Earth.
MINNEAPOLIS - Some studies have suggested that people who are younger when they enter puberty are more likely to later develop multiple sclerosis (MS). But a new study attributes that link to body mass index (BMI). The study is published in the March 20, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Irvine, Calif., March 20, 2019 - Here's something to chew on: One in four people are impacted by defects of the temporomandibular - or jaw - joint. Despite the pervasiveness of this affliction, treatments are lacking, and many sufferers resort to palliative measures to cope with the pain and debilitation it causes.
The prognosis for older patients with acute myeloid leukemia (AML) is poor: very few achieve remission and for those that don't the option is largely palliative.
Every year almost 1000 Australians die of the disease and clinical trials into new therapies for older patients have largely failed.
A new Australian drug trial has achieved a remarkable result, clearing the bone marrow of leukaemia in almost 60% of patients.
The trial was considered so effective that the US Food and Drug Administration approved its use last November for the treatment of AML.
A new study published in Infant and Child Development indicates that complications during birth may increase the risk that children will develop social anxiety by their pre-teen years.
March 20, 2019 - Salads were recently in the news--and off America's dinner tables--when romaine lettuce was recalled nationwide. Outbreaks of intestinal illness were traced to romaine lettuce contaminated with Escherichia coli (E. coli) bacteria.
These bacteria occur naturally in the intestines of warm-blooded animals. Because crops are grown in the natural environment, E.coli may get into the fields, contaminating produce. The results are potentially deadly for people who eat that produce.
The ecological bio-production of xylitol and cellulose nanofibers using modified yeast cells, from material produced by the paper industry has been achieved by a Japanese research team. This discovery could contribute to the development of a greener and more sustainable society. The findings were published on March 4, in Green Chemistry.
(Millbrook, NY) In the Americas, primate species likely to harbor Zika - and potentially transmit the virus - are common, abundant, and often live near people. So reports a new study published today in Epidemics. Findings are based on an innovative model developed by a collaborative team of researchers from Cary Institute of Ecosystem Studies and IBM Research through its Science for Social Good initiative.
Polyiodides exhibit useful electrochemical properties such as charge-carrier transportation, high electrolyte energy density, high redox reaction reversibility and a wide range of electrical conductivity, all depending on the forces exerted by the organic counter ions--chemical pressure. For this reason, polyiodides have been used in technical applications in electronic and electrochemical devices such as flow batteries, fuel cells, dye sensitized solar cells and optical devices.
EVANSTON, Ill. --- Women who shared their mother's womb with a male twin are less likely to graduate from high school or college, have earned less by their early 30s, and have lower fertility and marriage rates when compared with twins who are both female, according to new Northwestern University research.
Stanford researchers have devised a way to generate hydrogen fuel using solar power, electrodes and saltwater from San Francisco Bay.
The findings, published March 18 in Proceedings of the National Academy of Sciences, demonstrate a new way of separating hydrogen and oxygen gas from seawater via electricity. Existing water-splitting methods rely on highly purified water, which is a precious resource and costly to produce.
Currently, a practical, precise, minimally invasive way to measure cardiac output or heart function in children undergoing surgery does not exist. New research published in the Online First edition of Anesthesiology, the peer-reviewed medical journal of the American Society of Anesthesiologists (ASA), illustrates how a novel minimally invasive method using catheter-based ultrasound to measure heart function performed with similar precision to a traditional highly invasive device.
COLUMBUS, Ohio - For the first time, researchers have evidence that fibromyalgia can be reliably detected in blood samples - work they hope will pave the way for a simple, fast diagnosis.
In a study that appears in the Journal of Biological Chemistry, researchers from The Ohio State University report success in identifying biomarkers of fibromyalgia and differentiating it from a handful of other related diseases.
Research has increasingly shown that an employee's ability to mentally detach from work and recoup during non-work hours is important for their well-being. But a new study co-authored by a Portland State University professor suggests the opposite is just as important: employees who mentally reattach to work in the morning are more engaged at work.
ANN ARBOR, Mich. -- From choir and cheerleading to soccer and student council, extracurricular school activities keep students engaged - but cost may be among barriers that prevent some children from participating, a new national poll suggests.
