Researchers at the University of Pennsylvania and the University of Chicago used the Sloan Digital Sky Survey to find evidence that the dark matter halos surrounding galaxies and galaxy clusters have a discernible edge.
On Saturday, April 15, Tropical Cyclone 1B formed in the Northern Indian Ocean and it made landfall in Burma (Myanmar) on April 16. NASA's Terra satellite captured an image of the storm as if formed quickly and strengthened into a tropical storm that was renamed 'Maarutha.'
The American Society for Radiation Oncology (ASTRO) today issued a new clinical guideline for the management of oropharyngeal cancer.
Rice University computer scientists are mapping a new solution for interior navigational location detection by linking it to existing sensors in mobile devices.
For women who are overweight or obese and are unable to exercise, new research appearing online in The FASEB Journal suggests combining acupuncture with an electrical current may help.
Microscopic probes developed at Rice University simplify the process of measuring electrical activity in the cells of small living animals. The technique could revolutionize data-gathering for disease characterization and drug interactions.
When comparing victims of fraud to those who had never been victimized, lead authors Dr. Kang Lee and doctoral researcher Rebecca Judges at the Ontario Institute for Studies in Education (OISE) at the University of Toronto, along with researchers at Ryerson University, found that older victims have poorer cognitive abilities in everyday activities and are less conscientious and less honest than non-victims of the same age group.
South Carolina saw a 22 percent reduction in post-surgical deaths in hospitals that completed a voluntary, statewide program to implement the World Health Organization Surgical Safety Checklist.
In a new study, Yale researchers find that perceived risks of contracting Lyme disease on average cause a person in the Northeast to forego eight 73-minute outdoor trips per year -- exacting a total cost roughly $2.8 billion to $5 billion annually in the densely populated region.
Columbia Engineering Professor Nanfang Yu has invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. He built photonic integrated devices that had record-small footprints and were also able to maintain optimal performance over an unprecedented broad wavelength range. His method could lead to faster, more powerful, and more efficient optical chips, which in turn could transform optical communications and optical signal processing.
The use of antipsychotic medication in nearly 100 Massachusetts nursing homes was significantly reduced when staff was trained to recognize challenging behaviors of cognitively impaired residents as communication of their unmet needs, according to a new study led by Jennifer Tjia, MD, MSCE, associate professor of quantitative health sciences. Results of the study were published in JAMA Internal Medicine on April 17.
Silky chocolate, a better medical drug, or solar panels all require the same thing: just the right crystals making up the material. Now, scientists trying to understand the paths crystals take as they form have been able to influence that path by modifying the starting ingredient.
A UNC research team has identified a new cell in the body where HIV persists despite treatment. This discovery has major implications for cure research.
A new article published by JAMA Pediatrics reviews and analyzes a small collection of studies on fetal exposure to antidepressants and autism spectrum disorders.
Routine urinalysis for screening of genitourinary cancer isn't recommended by any major health group but patients who undergo urinalysis for a variety of other reasons are often found to have microscopic hematuria, which prompts further evaluation. A new article published by JAMA Internal Medicine explores the cost-effectiveness of four initial diagnostic protocols for these patients.
Study in Nature Nanotechnology describes new method to transform immune cells, while inside the body, into leukemia-fighting powerhouses.
Researchers at The University of Texas at Austin have identified glaciers in West Greenland that are most susceptible to thinning in the coming decades by analyzing how they're shaped. The research could help predict how much the Greenland Ice Sheet will contribute to future sea-level rise during the next century, a number that currently ranges from inches to feet.
MIT researchers have developed a way to make extremely high-resolution images of tissue samples, at a fraction of the cost of other techniques with similar resolution. Known as iterative expansion microscopy, relies on expanding tissue repeatedly, before imaging it with a conventional light microscope.
Duke scientists have modeled all of the steps by which nucleosides and their analogs are transported into cells by a specific molecule named the concentrative nucleoside transporter or CNT. The finding, published in Nature, provides important structural information that could be used to design smarter, more specific anticancer and antiviral drugs.
Brown biologists have developed a new system, described in Nature Genetics, that identified and tracked hundreds of genetic variations that alter the way DNA is spliced when cells make proteins, often leading to disease.
