Mississippi River diversions will produce new land, but slowly, Tulane study says

Posted on

Although river diversions that bring land building sediment to shrinking coastlands are the best solution to sustaining portions of the Mississippi Delta, a new Tulane University study concludes that the rate of land building will likely be dwarfed by the rate of wetland loss.

The study, published in the open-access journal Science Advances used optical dating to measure how fast the delta shoreline migrated seaward under natural conditions.

Massive University of Nebraska-Lincoln led study finds lectures still dominate STEM ed

Posted on

An analysis of more than 2,000 college classes in science, technology, engineering and math has imparted a lesson that might resonate with many students who sat through them: Enough with the lectures, already.

Published March 29 in the journal Science, the largest-ever observational study of undergraduate STEM education monitored nearly 550 faculty as they taught more than 700 courses at 25 institutions across the United States and Canada.

The University of Nebraska-Lincoln’s Marilyne Stains and her colleagues found that 55 percent of STEM classroom interactions consisted mostly of conventional lecturing, a style that prior research has identified as among the least effective at teaching and engaging students.

Another 27 percent featured interactive lectures that had students participating in some group activities or answering multiple-choice questions with handheld clickers. Just 18 percent emphasized a student-centered style heavy on group work and discussions.

The predominance of lecturing observed in the study persists despite many years of federal and state educational agencies advocating for more student-centered learning, the researchers said.

On April 4th at the 2018 National Rx Drug Abuse and Heroin Summit, NIH Director Francis S. Collins, M.D., Ph.D., launched the HEAL (Helping to End Addiction Long-term) Initiative, which is "an aggressive, trans-agency effort to speed scientific solutions to stem the national opioid public health crisis." Because of a funding increase provided by Congress, NIH is nearly doubling funding for research on opioid misuse/addiction and pain from approximately $600 million in fiscal year 2016 to $1.1 billion in fiscal year 2018.

HEAL will strengthen research across NIH to: 1) Prevent Addiction through Enhanced Pain Management and 2) Improve Treatments for Opioid Misuse Disorder and Addiction.
