BOSTON - Depression is the leading cause of disability worldwide, striking as many as one in four women and one in eight men in their lifetime. While more than 17 million adults in the United States struggled with the disease in 2017 according to the most recent government statistics, clinicians have long recognized that depression manifests in different ways across individuals; official diagnostic criteria include weight loss or weight gain, excessive sleeping or insomnia, inability to concentrate or obsessive rumination.
When we speak, we give little thought to how the words form in our brain before we say them. It's similar for deaf people using sign language.
Speaking and signing come naturally, except when we stumble over words, or swap one word for another when we speak or sign too quickly, are tired or preoccupied.
Fluency and the occasional disfluency both happen because of how we choose what to say or sign, when a neural mechanism takes place in our brains as we make decisions and monitor how we communicate.
Threat detection and prevention are essential to ensuring the safety and security of warfighters. Researchers have developed a way to speed up the processing of extremely large graphs and data, making the most efficient use of modern Army computational resources before and during Soldier deployment.
Whether there is life elsewhere in the universe is a question people have pondered for millennia; and within the last few decades, great strides have been made in our search for signs of life outside of our solar system.
Most newly discharged patients who recently recovered from COVID-19 produce virus-specific antibodies and T cells, suggests a study published on May 3rd in the journal Immunity, but the responses of different patients are not all the same. While the 14 patients examined in the study showed wide-ranging immune responses, results from the 6 of them that were assessed at two weeks after discharge suggest that antibodies were maintained for at least that long.
ITHACA, N.Y. - A new device that attaches to e-cigarettes can unobtrusively monitor inhalations - yielding important information for research about when and where people vape, how deeply they inhale and how much nicotine they consume.
The first-of-its-kind device, which can be easily attached to all types of e-cigarettes and other nicotine-delivery kits, can help fill gaps in knowledge about vaping that might help users curtail it, said Cornell Tech researchers who developed the tool.
DALLAS, May 4, 2020 -- The American Heart Association, together with 14 cardiovascular societies in North America, today issued joint guidance, "Safe Reintroduction of Cardiovascular Services during the COVID-19 Pandemic: Guidance from North American Society Leadership," to outline a systematic, phased approach to safely reintroducing cardiovascular procedures for diagnosis and treatment during the COVID-19 pandemic.
TAMPA, Fla (May 4, 2020) --- Black men and women have higher incidences than whites of developing advanced heart failure following a heart attack. Despite racial disparities in heart attacks (a leading contributor to heart failure), and rehospitalizations and deaths caused by heart disease, the underlying physiology accounting for worse cardiovascular outcomes among blacks is poorly understood.
HAMILTON, ON, May 4, 2020 - The massive international effort to map the entire human genome, completed in 2003, opened a new field we now know as personalized medicine.
The breakthrough, which identified the location and function of every human gene, offered the promise of medical care tailored specifically to individual patients, based on their personal genetic makeup.
When researchers identified a gene associated with a 44 per cent risk of breast cancer in women, for example, it seemed that protecting them might be as simple as deactivating that gene.
DALLAS, May 4, 2020 -- The COVID-19 pandemic has unmasked longstanding racial and ethnic health-related disparities, according to a new article published today in the American Heart Association's flagship journal Circulation.
AGA has published new expert recommendations in Gastroenterology: AGA Institute Rapid Review of the GI and Liver Manifestations of COVID-19, Meta-Analysis of International Data, and Recommendations for the Consultative Management of Patients with COVID-19.
Key guidance for gastroenterologists:
May 4, 2020n -- Researchers at Columbia University Mailman School of Public Health found that 92 percent of employers who responded to a survey on climate change and public health reported need for public health professionals with training in climate change will very likely increase in the next 5 to 10 years. While graduates of public health programs who focus on climate change are in demand in the current job market as well, these positions appear to be just a small proportion of the total number of jobs available in the field of public health.
New York, May 4, 2020 -- New Yorkers now think that the worst of the COVID-19 epidemic has passed but remain cautious about resuming normal activities. Many say they will not participate fully in everyday life until a vaccine is available. These are the major findings of the eighth weekly city and statewide tracking survey from the CUNY Graduate School of Public Health & Health Policy (CUNY SPH) conducted May 1-3.
Recommender systems are used in e-commerce to guide consumers with messages like "People who purchased this item also purchased ..." Past research has shown that these systems affect consumers' choices and generally boost sales, but few studies have examined how product-specific attributes or review ratings influence the effectiveness of such systems. A new study sought to determine how the impact of recommender systems (also called recommenders) is affected by factors such as product type, attributes, and other sources of information about products on retailers' websites.
CORVALLIS, Ore. - Researchers in Oregon State University's College of Agricultural Sciences have taken a step closer to solving one of nature's most remarkable mysteries: How do salmon, when it's time to spawn, find their way back from distant ocean locations to the stream where they hatched?
A new study into the life cycle of salmon, involving magnetic pulses, reinforces one hypothesis: The fish use microscopic crystals of magnetite in their tissue as both a map and compass and navigate via the Earth's magnetic field.
