Predicting risk of heart failure for diabetes patients with help from machine learning

Heart failure is an important potential complication of type 2 diabetes that occurs frequently and can lead to death or disability. Earlier this month, late-breaking trial results revealed that a new class of medications known as SGLT2 inhibitors may be helpful for patients with heart failure. These therapies may also be used in patients with diabetes to prevent heart failure from occurring in the first place. However, a way of accurately identifying which diabetes patients are most at risk for heart failure remains elusive. A new study led by investigators from Brigham and Women's Hospital and UT Southwestern Medical Center unveils a new, machine-learning derived model that can predict, with a high degree of accuracy, future heart failure among patients with diabetes. The team's findings are presented at the Heart Failure Society of America Annual Scientific Meeting in Philadelphia and simultaneously published in Diabetes Care.

Negative posts on Facebook business pages outweigh positive posts 2 to 1

There are more than 60 million business pages on Facebook and that number is from 2017. With those pages come scores of positive and negative posts generated by Facebook users. What researchers have seen is companies have very little control over what customers post, and negative posts can severely damage brands.

Microbes make chemicals for scent marking in a cat

Domestic cats, like many other mammals, use smelly secretions from anal sacs to mark territory and communicate with other animals. A new study from the Genome Center at the University of California, Davis shows that many odiferous compounds from a male cat are actually made not by the cat, but by a community of bacteria living in the anal sacs. The work is published Sept. 13 in PLOS ONE.

Ancient Australia was home to strange marsupial giants, some weighing over 1,000 kg

Palorchestid marsupials, an extinct group of Australian megafauna, had strange bodies and lifestyles unlike any living species, according to a study released September 13, 2019 in the open-access journal PLOS ONE by Hazel Richards of Monash University, Australia and colleagues.

How IL-6 allows the immune response to develop for a key cell, the T follicular helper

The body's immune response fights against infectious disease, and it safeguards against future infections through vaccination. However, if the immune response dysfunctions and attacks the body itself, it can cause autoimmune disease. Thus, a healthy immune response balances an instant readiness to combat infecting viruses or bacteria, while maintaining benign surveillance of the body's own tissues.

Gemini observatory captures multicolor image of first-ever interstellar comet

The first-ever comet from beyond our Solar System has been successfully imaged by the Gemini Observatory in multiple colors.

Nonphysician providers rarely interpret diagnostic imaging—except radiography, fluoroscopy

Although Medicare claims data confirm the increasing role of nurse practitioners and physician assistants (NPPs) in imaging-guided procedures across the United States, according to an ahead-of-print article published in the November issue of the American Journal of Roentgenology (AJR), NPPs still rarely render diagnostic imaging services, compared with the overall number of diagnostic imaging interpretations. When NPPs do render diagnostic imaging services, though, said services are overwhelmingly radiography and fluoroscopy.

Undergraduate engineers advance shock wave mitigation research

A team of undergraduate engineers at UC San Diego has discovered a method that could make materials more resilient against massive shocks such as earthquakes or explosions. The students, conducting research in the structural engineering lab of Professor Veronica Eliasson, used a shock tube to generate powerful explosions within the tube—at Mach 1.2 to be exact, meaning faster than the speed of sound. They then used an ultra high-speed camera to capture and analyze how materials with certain patterns fared.

How microtubules branch in new directions, a first look in animals

Cell biologist Thomas Maresca and senior research fellow Vikash Verma at the University of Massachusetts Amherst say they have, for the first time, directly observed and recorded in animal cells a pathway called branching microtubule nucleation, a mechanism in cell division that had been imaged in cellular extracts and plant cells but not directly observed in animal cells. Details appear this month in the Journal of Cell Biology.

New topological insulator reroutes photonic 'traffic' on the fly

Topological insulators are a game-changing class of materials; charged particles can flow freely on their edges and route themselves around defects, but can't pass through their interiors. This perfect surface conduction holds promise for fast and efficient electronic circuits, though engineers must contend with the fact that the interiors of such materials are effectively wasted space.
