Changes in vegetation shaped global temperatures over last 10,000 years
Follow the pollen. Records from past plant life tell the real story of global temperatures, according to research from a climate scientist at Washington University in St. Louis. Warmer temperatures brought plants — and then came even warmer temperatures, according to new model simulations published April 15 in Science Advances. Alexander Thompson, a postdoctoral research […]
Hold the salt: Study reveals how reducing sodium intake can help patients with heart failure: Surprising findings show a low-salt diet doesn’t prevent death or hospital visits, but does improve symptoms and quality of life.
For the past century people with weak hearts have been told to lower their salt intake, but until now there has been little scientific evidence behind the recommendation. The largest randomized clinical trial to look at sodium reduction and heart failure reported results simultaneously in The Lancet and at the American College of Cardiology’s 71st […]
Origins of diabetes may be different in men and women: Development of the disease depends on location and features of fat tissue in each sex
Over the past four decades, global cases of Type 2 diabetes mellitus have skyrocketed. According to the World Health Organization, the number of people estimated to have the disease jumped from 108 million in 1980 to 422 million in 2014, with the fastest growth observed in low- and middle-income countries. Although the disease is common, […]
Climate scientists reconsider the meaning and implications of drought in light of a changing world

Evidence for shared earthquakes between San Andreas and San Jacinto faults
The San Andreas and San Jacinto faults have ruptured simultaneously at least three times in the past 2,000 years, most recently in 1812, according to a new study by geologists at the University of California, Davis, and San Diego State University. The work was published Dec. 7 in the journal Geology. Large earthquakes involving multiple […]
Black, Hispanic Men Left Behind on Declining HIV Rates in the U.S.
While the number of new HIV infections fell among white men who have sex with men (MSM) over the past decade, infection rates among Black and Hispanic/Latino MSM were less positive, according to the CDC. In a new Vital Signs report, researchers highlighted racial disparities in HIV trends from 2010 to 2019, with new infections […]
New study proposes expansion of the universe directly impacts black hole growth
Over the past 6 years, gravitational wave observatories have been detecting black hole mergers, verifying a major prediction of Albert Einstein’s theory of gravity. But there is a problem — many of these black holes are unexpectedly large. Now, a team of researchers from the University of Hawai?i at M?noa, the University of Chicago, and […]
