Team develops EHR-based social needs screener to improve patient outcomes
Boston Medical Center (BMC) has implemented a social determinants of health screener for primary care patients in order to better identify and address patients' unmet social needs. Clinician researchers developed the electronic health record-based (EHR) model, THRIVE, which facilitates an automatic print out of referral information for resources based at the hospital and in the community when the patient asks for help with a need they have identified in the screener. The hospital's work, published in Medical Care, demonstrates an innovative systematic model that can help clinicians better address the social needs of patients to improve their overall health.

New machine learning algorithm can predict age and gender from just your Twitter profile
A new "demographic inference" tool developed by academics can make predictions based solely on the information in a person's social media profile (i.e. screen name, biography, profile photo, and name). The tool—which works in 32 languages—could pave the way for views expressed on social media to be factored in to popular survey methods.

Here's why your internet may be delivered by a drone someday soon
As the pilotless flying wing came in for a landing, winds suddenly picked up. Facebook Inc.'s Aquila drone—powered by the sun and wider than a Boeing 737 jetliner—struggled to adjust. Just before landing, part of the right wing broke off.

Fecal microbiota transplant found safe and effective in children with C. difficile
Diarrhea caused by Clostridiodes (formerly Clostridium) difficile infections is on the rise among children; one population-based study found a 12.5-fold increase in incidence from 1991 to 2009. For reasons that aren't clear, C. difficile is more frequently striking children without the usual risk factors, such as hospitalization or antibiotic exposure. One thing that is known is that C. diff disease is associated with an altered intestinal microbiota.

Lasers aim to replace scalpels in cutting-edge biopsy technique
To a patient, the analysis of a tissue biopsy sample to check for something like cancer may seem like a relatively simple process, even if it does mean giving up a small piece of flesh to be tested. The sample heads off to a lab, the patient heads home, and in several days the doctor calls with the results.

3-D images reveal how infants' heads change shape during birth
Using Magnetic Resonance Imaging (MRI), scientists have captured 3-D images that show how infants' brains and skulls change shape as they move through the birth canal just before delivery. Olivier Ami of Auvergne University in Clermont Ferrand, France, and colleagues present these findings in the open access journal PLOS ONE on May 15, 2019.

New AI sees like a human, filling in the blanks
Computer scientists at The University of Texas at Austin have taught an artificial intelligence agent how to do something that usually only humans can do—take a few quick glimpses around and infer its whole environment, a skill necessary for the development of effective search-and-rescue robots that one day can improve the effectiveness of dangerous missions. The team, led by professor Kristen Grauman, Ph.D. candidate Santhosh Ramakrishnan and former Ph.D. candidate Dinesh Jayaraman (now at the University of California, Berkeley) published their results today in the journal Science Robotics.

Do you trust politicians? Depends on how you define trust
There's more to trust than credence and faith, especially as it comes to politics. Research from Michigan State University and North Carolina State University presents new evidence to suggest that there are more layers to political trust than the public—and politicians themselves—previously thought.
