Advanced simulations created with one of the world’s most powerful supercomputers show the jets’ streams gradually change direction in the sky, or precess, as a result of space-time being dragged into the rotation of the black hole.
Researchers at Yale University have now grown a 2DEG system on gallium arsenide, a semiconductor that's efficient in absorbing and emitting light. This development is promising for new electronic devices that interact with light, such as new kinds of transistors, superconducting switches and gas sensors.
A new study co-authored by an American University professor found that job seekers who share their ups and downs with family and friends are more active than job seekers who don't.
The American Academy of Dermatology has released new guidelines of care for the management of basal cell carcinoma and cutaneous squamous cell carcinoma. These evidence-based guidelines cover best practices for the management of nonmelanoma skin cancer.
The NYC Health Department announced that since 2012, 10 outbreaks of foodborne illness were identified through a computer system jointly created with Columbia University’s Department of Computer Science. Launched in 2012, the computer system tracks foodborne illnesses based on certain keywords that appear in Yelp restaurant reviews. This strategy has helped Health Department staff identify approximately 1,500 complaints of foodborne illness in New York City each year, for a total of 8,523 since July 2012.
As healthy resolutions fill gyms and outdoor paths, two sports medicine doctors at Penn State Health Milton S. Hershey Medical Center remind those who work out to do it safely – whether exercising indoors or out.
Biological clocks throughout the body play a major role in human health and performance. Now, Texas A&M University researchers found that circadian rhythms could hold the key to novel therapies for glioblastoma, the most prevalent type of brain cancer in adults—and one with a grim prognosis.
Findings provide genetic basis underlying body weight and obesity risk.
Walmart was once considered the future of grocery shopping, offering consumers a slew of discounted choices, compared to the competition. Yet, market trends point toward a faster, cheaper, smaller and more streamlined experience. The result: One of the most common shopping experiences in American life is fundamentally changing, according to a new study in the journal Strategy and Leadership.
The new study shows that locations that experienced earthquakes are tied in proximity and timeliness to mass waste water injection sites. Further, the study indicates that tracking annual data on the injection well locations can help predict how corresponding earthquake activity will change. This new finding builds on previous studies showing that earthquake activity increases when wastewater injections increase.
In the first study of its kind, researchers from the Icahn School of Medicine at Mount Sinai found an elevated rate of language delay in girls at 30 months old born to mothers who used acetaminophen during pregnancy, but not in boys. This is the first study to examine language development in relation to acetaminophen levels in urine.
Geriatric patients seen by transitional care nurses in the emergency department (ED) are less likely to be admitted to the hospital, according to a study conducted at the Icahn School of Medicine at Mount Sinai.
A new method to predict tipping points – the moment at which sudden change occurs in complex networked systems – may offer insights that prevent colony collapse disorder (CCD), a phenomenon in which the majority of worker bees in a colony disappear, threatening the agricultural economy at a global level.
Reproduction among bald eagles in a remote national park in Minnesota was aided when their nests were protected from human disturbance, according to a study published today (Jan. 9, 2018) in the Journal of Applied Ecology.
Do you feel better about giving your uneaten sandwich to a homeless person than handing out cash? New research reveals fundamental truths—and contradictions—about how we choose to help others versus what we'd want for ourselves.
Machine learning and neural networks are the foundation of artificial intelligence and image recognition, but now they offer a bridge to see and recognize exotic insulating phases in quantum materials.
January 2018 issue of SOT journal honors the publication's 20-year history and features the newest, groundbreaking research in toxicology.
A revolutionary material harbors magnetism and massless electrons that travel near the speed of light—for future ultrasensitive, high-efficiency electronics and sensors.
Air pollution erodes the health of adults over age 65, a population particularly vulnerable to the effects of pneumonia.
Swimming, paddling, boating and fishing account for more than 90 million cases of gastrointestinal, respiratory, ear, eye and skin-related illnesses per year in the U.S. with an estimated annual cost of $2.9 billion, according to a new report by University of Illinois at Chicago researchers.This is the first time the cost associated with waterborne illnesses contracted during recreational activities in the U.
