For the first time, immunologists from The University of Texas at Austin have captured on video what happens when T-cells—the contract killers of the immune system, responsible for wiping out bacteria and viruses—undergo a type of assassin-training program before they get unleashed in the body. A new imaging technique that allowed for the videos, described today in the journal Nature Communications, holds promise for the fight against autoimmune disorders such as Type 1 diabetes.

Metals influence C-peptide hormone related to insulin
Metals such as zinc, copper and chromium bind to and influence a peptide involved in insulin production, according to new work from chemists at the University of California, Davis. The research is part of a new field of "metalloendocrinology" that takes a detailed look at the role of metals in biological processes in the body.

Experimental brain-controlled hearing aid decodes, identifies who you want to hear
Our brains have a remarkable knack for picking out individual voices in a noisy environment, like a crowded coffee shop or a busy city street. This is something that even the most advanced hearing aids struggle to do. But now Columbia engineers are announcing an experimental technology that mimics the brain's natural aptitude for detecting and amplifying any one voice from many. Powered by artificial intelligence, this brain-controlled hearing aid acts as an automatic filter, monitoring wearers' brain waves and boosting the voice they want to focus on.

A new era in 3-D printing
In the mid-15th century, a new technology that would change the course of history was invented. Johannes Gutenberg's printing press, with its movable type, promoted the dissemination of information and ideas that is widely recognized as a major contributing factor for the Renaissance.

Polymers jump through hoops on pathway to sustainable materials
Recyclable plastics that contain ring-shaped polymers may be a key to developing sustainable synthetic materials. Despite some promising advances, researchers said, a full understanding of how to processes ring polymers into practical materials remains elusive. In a new study, researchers identified a mechanism called "threading" that takes place when a polymer is stretched—a behavior not witnessed before. This new insight may lead to new processing methods for sustainable polymer materials.

Button batteries can rapidly damage stomach lining before symptoms appear
Damage to the lining of the stomach can occur quickly when children swallow button batteries; therefore, clinicians should consider prompt endoscopic removal, even when the child is symptom free and the battery has passed safely through the narrow esophagus, according to research presented at Digestive Disease Week (DDW) 2019. The recommendations represent a change from current practice of watching and waiting.

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.
