PITTSBURGH, Jan. 26, 2015 - Young adults who spend a lot of time on social media during the day or check it frequently throughout the week are more likely to suffer sleep disturbances than their peers who use social media less, according to new research from the University of Pittsburgh School of Medicine.

Published online and scheduled for the April issue of the journal Preventive Medicine, the study indicates that physicians should consider asking young adult patients about social media habits when assessing sleep issues. The research was supported by the National Institutes of Health (NIH).

Marion Nestle, Vani Hari, Michael Pollan; we have all seen messages from self-appointed "food police" telling us that sugary snacks are bad, GMOs are bad, everything except organic vegetables (they seem to believe those have no pesticides or genetic modification) is bad.

But they may be doing more harm than good, not just for public acceptance of science, but for the people they claim to want to help. The government is doing the same thing. They are increasing their use of public service announcements (PSAs) about the dangers of unhealthy eating. 

There are not many "nicotine naïve" teens using e-cigarettes - who have never tried cigarettes - but of those few who do, they are more likely to try the real thing a year later than those who have never vaped, indicates survey results in the journal Tobacco Control.

However, subsequent regular smoking is linked only to higher levels of e-cigarette use at the outset, which sends statistical experts into all kinds of alarm.

(CAMBRIDGE, Massachusetts) - Researchers in the field of mechanobiology are evolving our understanding of health by revealing new insights into how the body's physical forces and mechanics impact development, physiological health, and prevention and treatment of disease. At the Wyss Institute for Biologically Inspired Engineering at Harvard University, engineers and biomedical scientists have assembled to form collaborative teams that are helping to drive this exciting area of research forward toward real-world applications. Now, a new study suggests mechanically-driven therapies that promote skeletal muscle regeneration through direct physical stimulation could one day replace or enhance drug and cell-based regenerative treatments.

NASA satellites obtained a number of different views of the great winter storm that left many snowfall records from Virginia to New York City from January 22 to 24, 2016. RapidScat provided a look at the strong winds that led to flooding in southern New Jersey, while NASA's Aqua satellite and NASA/USGS's Landsat satellite provided images of the post-storm snowy blanket.

The RapidScat instrument flies aboard the International Space Station and measures surface winds over the ocean. On Jan. 23 at 5 a.m. EST, RapidScat showed sustained winds as strong as 45 meters per second (100 mph/162 kph) along the coast of southern New Jersey, which included areas from Cape May to Atlantic City. Those winds led to flooding along coastal areas.

A new procedure developed by surgeons at The University of Texas MD Anderson Cancer Center improves the accuracy of axillary staging and pathologic evaluation in clinically node-positive breast cancer, and reduces the need for a more invasive procedure with debilitating complications.

The research, published in the Journal of Clinical Oncology, has changed treatment guidelines at the institution for a select group of breast cancer patients with lymph node metastasis, who will now receive Targeted Axillary Dissection (TAD).

The TAD procedure involves removing sentinel lymph nodes, as well as additional cancerous lymph nodes found during diagnosis. At the time of diagnosis, those select nodes are clipped for identification during later surgery.
