New evidence of a preventative therapy for gout

Dom, 09/16/2018 - 22:00
Solomon and colleagues found a significant reduction in risk of gout attacks among patients who received the drug that targets a key inflammatory molecule, suggesting a new target for therapeutic strategies to prevent gout attacks. Their findings are published online today in Annals of Internal Medicine.

UCLA researchers develop mechanism for characterizing function of rare tumor cells

Dom, 09/16/2018 - 22:00
UCLA researchers have created a quick and effective mechanism to measure how these circulating tumor cells perform functions that drive cancer.

Thinking beyond yourself can make you more open to healthy lifestyle choices

Dom, 09/16/2018 - 22:00
Many people feel threatened when reminded of their unhealthy behavior. However, a group of 220 sedentary adults became more receptive to health advice -- and more active -- after being primed to either think about their most important values or to make well-wishes for others.

NASA's TESS shares first science image in hunt to find new worlds

Dom, 09/16/2018 - 22:00
NASA's Transiting Exoplanet Survey Satellite, which began science operations in July, has released its first full frame image using all four of its cameras.

More ships and more clouds mean cooling in the arctic

Dom, 09/16/2018 - 22:00
UConn professor of geology Scott Stephenson and colleagues recently modeled the future of trans-Arctic shipping routes and found that increased emissions will spell a trend of slowed cooling in the region. Though the researchers stress this is in no way an endorsement to trans-Arctic shipping or a means to mitigate climate change, however the results illustrate the complexities in understanding how human activities impact the climate.

Catastrophic construction: Storms can build reef islands in atoll regions

Dom, 09/16/2018 - 22:00
Tropical storms, with waves reaching up to 10-meters-high, can wallop coral reef islands. As global temperatures increase, some scientists suggest that such storms will become more frequent and intense over the next few decades. Additionally, potential sea level rise is perceived as a threat to the continued existence of these remote, low-lying communities.

Micronizing ocean plastics threaten sea turtle populations, ocean life cycle

Dom, 09/16/2018 - 22:00
Ingestion of degrading ocean plastics likely poses a substantial risk to the survival of post-hatchling sea turtles because the particles can lead to blockages and nutritional deficiencies, according to new research.

New world record magnetic field

Dom, 09/16/2018 - 22:00
Scientists at the University of Tokyo have recorded the largest magnetic field ever generated indoors -- a whopping 1,200 tesla, as measured in the standard units of magnetic field strength. The high magnetic field also has implications for nuclear fusion reactors, a tantalizing if unrealized potential future source of abundant clean energy. The experiments that set the new world record are described in this week's Review of Scientific Instruments.

NASA sees Post-Tropical Cyclone Helene affecting Ireland, United Kingdom

Dom, 09/16/2018 - 22:00
Post-tropical cyclone Helene developed off the west coast of Africa and moved north then northeast where it is now raining on parts of Ireland and the United Kingdom. Clouds and rainfall connected to Helene are already affecting those countries.

Compact fiber laser may enable wearable tech and better endoscopes

Dom, 09/16/2018 - 22:00
By creating a new twist on fiber optic sensors, researchers in China have developed a smart, flexible photoacoustic imaging technique that may have potential applications in wearable devices, instrumentation and medical diagnostics.

Significant disparities in college student mental health treatment across race/ethnicity

Dom, 09/16/2018 - 22:00
The first nationally representative study since the 1990s to examine mental health among college students of color, led by a Boston University School of Public Health (BUSPH) researcher, shows significant disparities in treatment across race/ethnicity.

NASA catches Tropical Cyclone 01s's last breath in southern Indian Ocean

Dom, 09/16/2018 - 22:00
The first tropical cyclone of the Southern Indian Ocean season, 01S, formed on Sept. 15 and was already fizzling two days later. Visible satellite imagery from NASA's Aqua satellite revealed recently developed tropical cyclone 01S was already fading.

UVA identifies brain's lymphatic vessels as new avenue to treat multiple sclerosis

Dom, 09/16/2018 - 22:00
The vessels appear to carry previously unknown messages from the brain to the immune system that ultimately cause the disease symptoms. Blocking those messages may offer doctors a new way to treat a potentially devastating condition that affects more than 2 million people.

More than 4 billion birds stream overhead during fall migration

Dom, 09/16/2018 - 22:00
Using cloud computing and data from 143 weather radar stations across the continental United States, Cornell Lab of Ornithology researchers can now estimate how many birds migrate through the US and the toll that winter and these nocturnal journeys take. Their findings are published in Nature Ecology & Evolution.

Do rock climbers seek out high-risk climbs?

Dom, 09/16/2018 - 22:00
The sport of rock climbing is gaining international attention, having been approved for inclusion in the 2020 Olympic Games. But news headlines about the sport are still dominated by reports of gruesome injuries and near-death falls. Are rock climbers going out of their way to seek these risks? A new study published in Risk Analysis: An International Journal reveals that decreasing the level of injury risk at a climbing site generates substantial welfare gains for climbers.

Shifting focus from life extension to 'healthspan' extension

Dom, 09/16/2018 - 22:00
The Journal of the American Medical Association published an article by University of Illinois at Chicago epidemiologist S. Jay Olshansky on the need for researchers and clinicians to focus less on prolonging lifespan and more on prolonging 'healthspan.'

NASA finds Tropical Depression Joyce continues to lose it

Dom, 09/16/2018 - 22:00
Visible and infrared satellite imagery from NASA's Aqua satellite revealed Tropical Storm Joyce continues to become more disorganized.

Individual, societal changes needed to combat obesity

Dom, 09/16/2018 - 22:00
Fighting the obesity epidemic in the US will require changes at both the individual and societal level, according to a review paper published today in the Journal of the American College of Cardiology. This paper is part of an eight-part health promotion series where each paper will focus on a different risk factor for cardiovascular disease.

Pre-activating cath labs prior to STEMI arrival speeds treatment, reduces risk

Dom, 09/16/2018 - 22:00
ST-elevation myocardial infarction (STEMI) patients have a higher chance of survival if emergency medical service (EMS) teams notify the cardiac catherization lab at the hospital where the patient will be transported in advance of the patient's arrival, according to a study published today in JACC: Cardiovascular Interventions. However, hospital cardiac catherization labs in the US are only being notified (pre-activated) at least 10 minutes in advance 41 percent of the time.

Characterizing pig hippocampus could improve translational neuroscience

Dom, 09/16/2018 - 22:00
Researchers have taken further steps toward developing a superior animal model of neurological conditions such as traumatic brain injury and epilepsy, according to a study of miniature pigs published in eNeuro. The results establish the pig as a promising preclinical research model for hippocampal-dependent human memory disorders.
