Political ads have little persuasive power, study finds

Every four years, U.S. presidential campaigns collectively spend billions of dollars flooding TV screens across the country with political ads. But a new study shows that, regardless of content, context, or audience, those pricey commercials do little to persuade voters.

Asphalt adds to air pollution, especially on hot, sunny days

Asphalt is a near-ubiquitous substance -- it's found in roads, on roofs and in driveways -- but its chemical emissions rarely figure into urban air quality management plans. A new study finds that asphalt is a significant source of air pollutants in urban areas, especially on hot and sunny days.

Gamifying interventions may improve mental health

A new randomized control trial has found that turning mobile mental health intervention into a smartphone game can potentially improve well-being. The five-week study shows that gamifying the content of mobile interventions improved resilience, a key character trait that reduces the susceptibility to depression, stress, and anxiety.

Why naming neurons can help cure brain disease

A group of 74 scientists proposed the use of single-cell RNA sequencing as the skeleton for a unified classification of cortical neurons. The 'Copenhagen Classification' came out of an international meeting on cortical neurons two years ago.

An unprecedented discovery of cell fusion

Understanding how bacteria interact is critical to solving growing problems such as antibiotic resistance, in which infectious bacteria form defenses to thwart the medicines used to fight them. Researchers have discovered that bacterial cells from different species can combine into unique hybrid cells by fusing their cell walls and membranes and sharing cellular contents, including proteins and...

Study examines the benefits of virtual stroke rehabilitation programs

While virtual medical and rehabilitation appointments seemed novel when COVID-19 first appeared, they now seem to be part of the new norm and might be paving the way to the future. A recent review paper has determined that virtual appointments, in the form of telerehabilitation, also work for people recovering from a stroke.

Using tattoo ink to find cancer

The humble ink in a tattoo artist's needle could be the key to improving the detection of cancer. Researchers recently developed new imaging contrast agents using common dyes such as tattoo ink and food dyes. When these dyes are attached to nanoparticles, they can illuminate cancers, allowing medical professionals to better differentiate between cancer cells and normal adjacent cells.

Zooming in on dark matter

Cosmologists have zoomed in on the smallest clumps of dark matter in a virtual universe - which could help us to find the real thing in space.
