If a post is not popular, you will never see it, so views count, but it is the message and not the popularity of it that persuades people, according to a new paper.

819 demographically diverse American adults aged 18-35 were shown two YouTube videos either for or against vaping. The pro-vaping videos were commercials for e-cigarette brands. The anti-vaping videos were public service announcements produced by anti-tobacco groups. What was changed was the view numbers that participants saw for the videos.

Participants saw view numbers either around 10, 100, 100,000 or 1,000,000.

The remains of 36 bubonic plague victims from a 16th century mass grave in Germany provide evidence that evolutionary adaptive processes, driven by the disease, may have conferred immunity on later generations of people from the region.

The researchers collected DNA samples from the inner ear bones of individuals in a mass grave in the southern German city of Ellwangen which experienced bubonic plague outbreaks in the 16th and 17th centuries. Then they took DNA samples from 50 current residents of the town. They compared their frequency spectra - the distribution of gene variants in a given sample - for a large panel of immunity-related genes and found that innate immune markers increased in frequency in modern people from the town compared to plague victims.

Men may be more reluctant to go to a doctor for chest pain but when they get to a care facility, a new analysis finds they get it quicker than women.

In this look at the data, all of the patients were younger, from 18-55. 

Compared with men, women were triaged less urgently, waited longer to be seen, and were less likely to undergo basic tests or be hospitalized or admitted for observation to diagnose a heart attack, according to a demographic look presented at the American College of Cardiology meeting. 

A new analysis finds that nearly 50 percent of people who have children with a partner who suffers from schizophrenia or bipolar disorder themselves meet the criteria for a mental disorder.

Antarctica’s fourth largest ice shelf, the Larsen C Ice Shelf located on the Antarctic Peninsula, risks collapse due to mountain winds, according to a recent presentation at annual meeting of the European Geophysical Union.

The ClinicalTrials.gov data bank, managed by the National Institutes of Health (NIH)/National Library of Medicine, requires trial sponsors to register applicable clinical trials within 21 days after the first human subject is enrolled and submit certain summary results information for those trials, generally no later than one year after the study’s completion date unless a deadline extension is obtained.
