An unusually high failure rate in the high-mounted, center brake light was observed in a survey of normal local traffic. Such failure increases the potential for delay or error in perception of the rear lights by following drivers.

This study investigates brake wear particle (BWP) emissions from light-duty electric vehicles (EVs) and heavy-duty vehicles (HDVs) using a self-developed whole-vehicle testing system and a modified brake dynamometer. The results show that regenerative braking significantly reduces emissions: weak and strong regenerative braking modes reduce brake wear PM by 75 % and 87 %, and brake wear PM by 90 % and 95 %, respectively. HDVs with drum brakes produce lower emissions and higher PM/PM ratios than those with disc brakes.

A major challenge in the field of synthetic motors relates to mimicking the precise, motion of biological motor proteins, which mediates processes such as cargo transport, cell locomotion, and cell division. To address this challenge, we developed a system to control the motion of DNA-based synthetic motors using light. DNA motors are composed of a central chassis particle modified with DNA "legs" that hybridize to RNA "fuel", and move upon enzymatic consumption of RNA.

Unlabelled: Enteroviruses cause nearly 1 billion global infections annually and are associated with a diverse array of human illnesses. Among these, myocarditis and the resulting chronic inflammation have been recognized as major contributing factors to virus-induced heart failure. Despite our growing understanding, very limited therapeutic strategies have been developed to address the pathological consequences of virus-induced chronic innate immune activation.

As tailpipe emissions have decreased, there is a growing focus on the relative contribution of non-exhaust sources of vehicle emissions. Addressing these emissions is key to better evaluating and reducing vehicles' impact on air quality and public health. Tailoring solutions for different non-exhaust sources, including brake emissions, is essential for achieving sustainable mobility.

Background/objectives: Studies indicate a decline in children's physical activity (PA) levels, active mobility, and psychomotor skills, reflected in poorer cycling abilities. These trends are worrying given the rising prevalence of childhood obesity and sedentary lifestyles. This study assessed cycling skills among primary school children in Lower Austria, comparing self-perceptions with objective assessments, and explores the relationship between cycling skills, PA levels, and school performance, as well as the impact of cycling training on skill development.
