Around 40-60% of healthy adults carry around the fungus Candida albicans in their mouth or guts; in immunocompromised people, however, this normally harmless cohabitant becomes a deadly pathogen. A report in the journal GENETICS describes the genomes of three Candida albicans strains isolated from the barks of oak trees in an ancient wood pasture, providing genetic evidence that this yeast can live on plants for extended periods of time.

The research findings, published Feb.
The pros and cons of policing methods have been heavily debated for decades in the United States.Now, a Florida State University-led team of researchers has created a model to measure the differences between two distinct approaches to policing — the warrior approach and the guardian approach.Assistant Professor Kyle McLean said the concepts — which attracted interest after the release of former President Barack Obama’s Task Force on 21st Century Policing report in May 2015 — had largely been theory up until now.
Radiologists quickly learn to read 3D mammography more accurately than they read standard 2D mammograms, a first-of-its-kind study by a UC Davis researcher has found. Published today in Radiology, the study led by Diana Miglioretti, UC Davis dean’s professor of biostatistics, found that radiologists who interpret traditional mammograms, which are two-dimensional, required little start up time for transitioning to reading digital breast tomosynthesis (DBT), or 3D mammography, with improved screening accuracy

Providing additional health-care services for heart failure patients to help them transition from hospital to home does not improve their outcome, according to research led by the Population Health Research Institute (PHRI) of McMaster University and Hamilton Health Sciences (HHS). The conclusion comes from a trial that followed the health status of almost 2,500 adults hospitalized for heart failure in hospitals across Ontario, Canada.

How good is the research on the success or failure of the system that verifies your identity when you log into a computer, smartphone or other device? Chances are it’s not good, and that’s a major security and privacy issue that should be fixed, according to a Rutgers University–New Brunswick study that proposes a novel solution.
Brain cells recorded as among the least electrically active during a specific task may be the most important to doing it right.
FINDINGS Researchers found that more than 97 percent of the surgeries for appendicitis were laparoscopic, or minimally invasive, and most patients were discharged the same day or the next day. Only 3 percent of the procedures resulted in complications. Rates of unnecessary surgery — removing a “normal” appendix — were low (less than 4 percent), but were much higher in people without imaging studies before their operation (nearly 20 percent).

About one in five adults in a representative sample of Americans had watched at least part of a beheading video created and posted online by the Islamic State group (formerly known as ISIS), according to a new study by the University of California, Irvine. Researchers also found that fear of terrorism and having a history of violent victimization appear to draw individuals to this highly graphic coverage – and that watching such videos was associated with global distress and fear of the future about two years after they went viral.
In a paper published Feb. 25 in Nature, scientists report that they have developed a system to trap individual excitons — bound pairs of electrons and associated positive charges. This system could form the basis of a novel platform to monitor excitons with precision and develop new quantum technologies.

A team led by Paul Steen, professor of engineering at Cornell University, has created a periodic table of droplet motions, inspired in part by parallels between the symmetries of atomic orbitals, which determine elements’ positions on the classic periodic table, and the energies that determine droplet shapes.
While some Mexican immigrants give positive accounts about migrating to and living in the United States, their health status tells a different story. In a small study in Columbus, researchers found that many migrants celebrated living in Columbus. However, they also experienced discrimination and exhibited physical signs of stress, such as high blood pressure, high blood sugar and obesity.
