Coastal elevations in sections of the Everglades are up by over 2 inches due to major hurricanes washing up sediment and mangrove tree-boosting nutrients, according to a study in Proceedings of the National Academy of Sciences. Hurricanes in 2005 and 2017 deposited sediment and mud, "and we found out this provides natural fertilization that helps the mangroves," said study lead author Edward Castaneda-Moya.
Methane emissions from fossil fuels may have been underestimated by as much as 40%, according to data gathered globally as far back 1750, and published in Nature. Each ice core melted by the research team for sampling weight around 1,000 kilograms.
Eating junk food may disrupt the hippocampus, which affects memory and appetite control in the brain, causing people to overindulge, according to findings published in Royal Society Open Science. Researchers recorded changes in appetite control in study participants within one week of starting a junk food diet.
Fossils of several species of fish have been found in the Sahara desert and likely populated lakes that existed there between 10,200 and 4,650 years ago, according to findings published in PLOS ONE. Researchers say people and animals who populated the area at that time ate a diet that included catfish and tilapia before climate change dried up the lakes, swamps and ponds.
Hispanic and non-Hispanic post-menopausal women had a 6% increased fasting insulin and an over 7% increase in insulin resistance for every additional hour in average sitting time per day, which were 8.5 hours and 9 hours, respectively. The study published in the Journal of the American Heart Association also revealed that every 15 minutes added in uninterrupted sitting was tied to approximately 5% higher fasting blood glucose among Hispanic women, compared to less than 1% increase among non-Hispanic women.
A 15-year study published in the Journal of Women's Health has found women diagnosed with preeclampsia had a significantly higher risk of later cardiovascular disease events, including myocardial infarction, all-cause death and a nearly fivefold greater risk of cardiovascular death. The researchers said there were limitations within the study and suggested the need for further investigation.
The NIH has awarded a $1.6 million grant to Dr. Prakash Chinnaiyan of Beaumont Health and the Oakland University William Beaumont School of Medicine in Michigan. The funds will go toward a study of glioblastoma and the role metabolites play in brain cancer development.
The National Institutes of Health intends to improve the diversity of grant recipients by providing funding to institutions that plan to hire at least 10 junior faculty members in the next two years. The initiative calls for institutions to leave academic ranks and areas of expertise unspecified in the hopes of yielding diverse applicant groups.
Sigma Xi's Grants in Aid of Research program is just two years from its centennial. The program awards funding to undergraduate and graduate student researchers worldwide. Apply by March 15 to be considered in the next proposal review cycle. In the last cycle, the program awarded 95 students. Collectively, they received $99,811.
This year's Annual Meeting and Student Research Conference will explore the opportunities that come from bringing together art and science. What could a collaboration with artists do to help advance your research, or to share it with a broad audience? We're meeting November 5-8 in Alexandria, Virginia. You can save 20% with the early bird registration discount.
