Lasers create miniature robots from bubbles

Robots are widely used to build cars, paint airplanes and sew clothing in factories, but the assembly of microscopic components, such as those for biomedical applications, has not yet been automated. Lasers could be the solution. ...

Where antibiotic resistance comes from

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started ...

A DNA-based nanogel for targeted chemotherapy

Current chemotherapy regimens slow cancer progression and save lives, but these powerful drugs affect both healthy and cancerous cells. Now, researchers reporting in ACS' Nano Letters have designed DNA-based nanogels that ...

Tracking flight trajectory of evaporating cough droplets

The ongoing COVID-19 pandemic has led many researchers to study airborne droplet transmission in different conditions and environments. The latest studies are starting to incorporate important aspects of fluid physics to ...

Study finds go-to hormone for cycad propagation ineffective

The newly published thesis research of University of Guam Master of Environmental Science graduate Benjamin Deloso now adds to the body of knowledge about asexual propagation of the most endangered plant group in the world, ...

Pandemic provides unique opportunity for atmospheric chemists

As the COVID-19 pandemic slowed travel and business around the world, pollution emission rates dropped in response. With fewer cars on the road and clearer skies, atmospheric chemists jumped at the opportunity to study the ...
