Examining embryo model ethics beyond box-checking

In science, ethical guidelines ensure that research takes place in a way that respects public trust and is conducted responsibly. Traditional ethics approval procedures work well for projects following established practices, ...

A 'stemness checkpoint' helps control stem cell identity

A study published in Cell Research advances a central idea in stem cell biology by identifying a checkpoint that controls the identity of many different types of stem cells across developmental stages. For nearly two decades, ...

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 ...
