Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations.
CHICAGO – Almost half of all heart attacks cause no obvious symptoms, yet they can still be life-threatening, according to research on more than 9,000 middle-aged men and women. It's one of the biggest studies to examine so-called silent heart attacks, and to also explore them across racial and gender groups. Researchers at Wake Forest University's medical school led the government-funded study. Results were published online Monday in the American Heart Association's journal, Circulation. Middle-aged adults from four U.S. communities were enrolled: Washington County, Maryland; suburban Minneapolis; Jackson, Mississippi, and Forsyth County, North Carolina.
Where you live can affect your stress levels. And a recent study showed just that when it named Detroit the most stressed city in the US. A new review, compiled by WalletHub, determined the Motor City to be the worst when it came to tension in both work and personal life. It came out on top in highest poverty rate, highest unemployment rate and the percentage of adults with inadequate sleep. The bottom five all fell in the eastern half of the US: Newark, New Jersey; Cleveland, Ohio; Birmingham, Alabama; and Toledo, Ohio.
As climate change dries the Southwest, cities are where the water and the green plants--and the mule deer--will be. Cougars will become increasingly common visitors to Southwestern cities like Las Vegas in the next few decades as climate change drives their prey to greener urban pastures, a new study suggests. The hot, dry Southwest is projected to become even hotter and drier as mounting fossil fuel emissions trigger more frequent, intense and long-lasting droughts. That change will reduce the cougar population, according to research presented Monday at the American Geophysical Union Fall Meeting in San Francisco--but it may also cause more of the animals to show up in well-watered towns. David Stoner of Utah State University and his colleagues used satellite images measuring the food content of natural vegetation in Utah, Nevada, and Arizona to model how the extreme drought year of 2002--considered a taste of what's to come in the Southwest--affected the population density of cougars and of mule deer, the big cats' favorite prey.
Migration patterns for 2016 show that Americans tended to move away from high-tax states and into states where residents keep more of what they earn. United Van Lines, the nation's largest moving company, recently released its annual movers study report showing that South Dakota overtook Oregon as the top inbound destination. Generally, more people moved toward the west, and states in the northeast saw the largest exodus of residents. The top four outbound states in 2016, in order, were New Jersey, Illinois, New York and Connecticut. The Tax Foundation pointed out in a recent blog post that those results are similar to the organization's annual state business tax climate index.
