Cell 'snowball' may be answer to large-scale tissue engineering

Cell cultures—single layers of cells grown in a small dish—have enabled researchers to study biological growth, develop or test drugs and even discover what causes some diseases. Cell spheroids, 3D versions of cell cultures ...

Stopping algae blooms with bacteria-busting buoys

Algae blooms make a pond's surface shine in mesmerizing green hues. But if the microorganisms responsible are cyanobacteria, they can also release toxins that harm humans and wildlife alike. A team reporting in ACS ES&T Water ...

Seed banks may complicate gene drives aimed at controlling weeds

Gene drives—a genetic engineering approach that quickly spreads specific genetic changes throughout a population, whether to kill it off or add a new trait—may have potential for controlling weeds. But so far, gene drives ...

Watering smarter, not more: A modern-day robotic divining rod

Advanced technology can help farmers get to the root of a growing problem—overwatering in an era of increasing drought and water scarcity. A new UC Riverside system can map soil moisture tree by tree, so growers water only ...
