How the respiratory tract microbiome influences the severity of bacterial pneumonia

Pneumonia is an infection of the lung alveoli caused by bacteria, viruses or fungi. It is one of the leading causes of morbidity and mortality worldwide, representing a clinical and economic burden and a global public health problem. The microbial ecosystem (or microbiome) of the human respiratory tract colonizes different niches. The respiratory tract microbiome is of interest to scientists as it...

Benefits, risks in state-mandated school-based BMI assessments

A resource economist finds mandated in-school Body Mass Index assessments adopted in varying forms by 24 states to combat childhood obesity have the potential to improve the health of some students while introducing body-image issues for others. The research is believed to be the first to assess these policies as a whole, rather than in single states or school districts.

New neural insights into processing uncertainty in obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) is a neurological disorder characterized by repeated behaviors such as cleaning and checking despite clear objective evidence of cleanliness, orderliness, and correctness. Although the disease is often mischaracterized as a disorder of 'fussiness,' the disorder actually stems from difficulty in processing uncertainty. However, the neural underpinnings of that...

New research provides hope for Parkinson's disease symptom control

Finding the right medication regimen to treat Parkinson's disease (PD) is a complex healthcare challenge. Wearable health trackers provide physicians with a detailed window into patients' symptoms, but translating this complex data into useful treatment insights can be difficult. New research accomplishes just that. Researchers found that combining wearable health tracker data with...

A self-powered sensor made from plants

The story of Qi Chen's research is full of serendipity. In the first year of her Ph.D., she was hanging out with friends at the University's Zernike campus, discussing the topics of their research. Chen told them she was going to study foam-like materials. A friend was casually peeling the stem of a grass-like plant, thereby revealing its insides that appeared to have an open and airy structure....

Most nitrogen from farms goes into the 'nitrogen blanket' and direct deposition is very local: Report

On behalf of the Mesdag Zuivelfonds, researchers from the University of Amsterdam have measured within which radius around dairy farms the nitrogen emitted by the farm is deposited. By far the largest part of the emitted nitrogen (≈ 90%) ends up in higher air layers of the atmosphere and will precipitate elsewhere. Within the measured area, with a radius of 500 meters around the farm, most of...
