A new wearable medical device can quickly alert a person if they are having cardiovascular trouble or if it’s simply time to put on some skin moisturizer, reports a Northwestern University and University of Illinois at Urbana-Champaign study. The small device, approximately five centimeters square, can be placed directly on the skin and worn 24/7 [...]

The majority of drugs used to treat asthma today are the same ones that were used 50 years ago. New drugs are urgently needed to treat this chronic respiratory disease, which causes nearly 25 million people in the United States alone to wheeze, cough, and find it difficult at best to take a deep breath.

Bacterial pneumonia in adults carries an elevated risk for adverse cardiac events (such as heart failure, arrhythmias, and heart attacks) that contribute substantially to mortality — but how the heart is compromised has been unclear. A study published on in PLOS Pathogens now demonstrates that Streptococcus pneumoniae, the bacterium responsible for most cases of bacterial [...]
