Sneezing from cats or dust? Safe UV light may neutralize allergens in minutes

Sneezing from cats, dust mites, or mold may one day be preventable with a flip of a switch. Researchers at CU Boulder found that UV222 light can alter allergen proteins, reducing allergic reactions without dangerous side effects. Within 30 minutes, airborne allergens decreased by up to 25%. The team imagines portable devices that could shield people in homes, schools, and workplaces from harmful triggers.

Wildfire smoke could kill 70,000 Americans a year by 2050

Wildfires are no longer a seasonal nuisance but a deadly, nationwide health crisis. Fueled by climate change, smoke is spreading farther and lingering longer, with new research warning of tens of thousands of additional deaths annually by mid-century. The health costs alone could surpass all other climate damages combined, revealing wildfire smoke as one of the most underestimated threats of our warming world.

Rare diseases: Over 300 million patients affected worldwide

Rare diseases represent a global problem. Until now, the lack of data made it difficult to estimate their prevalence. The Orphanet database, which contains the largest amount of epidemiological data on these diseases taken from the scientific literature, has made it possible to obtain a global estimate.

Scientists develop test for uncommon brain diseases

Scientists have developed an ultrasensitive new test to detect abnormal forms of the protein tau associated with uncommon types of neurodegenerative diseases called tauopathies. This advance gives them hope of using cerebrospinal fluid, or CSF — an accessible patient sample — to diagnose these and perhaps other, more common neurological diseases, such as Alzheimer's disease.

Are some urban settings riskier for traffic injury or death? We know less than you think

How risky is travel in the US? It gets tricky. Despite a lot of research on the dangers of traffic injury and death, there's a lack of clarity on the role of the built environment (roadway designs and adjoining development) and its risk effects. Before we can know how risky a given built environment is, we have to know how many people are traveling there, and in many cases, for pedestrians and cyclists, this data is not available.

Common denominator that triggers asthma in favorable environments

Some so-called pro-allergic environments strongly promote the development of asthma and are responsible for the dramatic increase in the prevalence of asthma, especially in industrialized countries. Researchers at the GIGA of the University of Liège have identified how all these pro-allergic environments act in the same way on the pulmonary immune system to induce the development of allergic asthma.
