Researchers at Gladstone Institutes have uncovered an unusual bacterial immune system that operates in reverse of known defenses. The discovery, published in Molecular Cell, details the mechanics of "type VI retrons"—a counterintuitive ...
Marine bacteria have evolved to bypass the copper-based coatings applied to ship hulls to stop the growth of barnacles, algae and other marine life. This necessitates new methods for managing biofouling—the unwanted accumulation ...
A small number of random genetic mutations cause simple RNA droplets to transform into cell-like structures. In this process, they form cavities, can move and are able to take up cargo.
A new antiviral defense system discovered by Columbia scientists could be adapted in the future into a gene editor that slows down aging in our cells and improves cancer therapies. At the same time, the discovery also sheds ...
The decline of pollinator species due to habitat loss and pesticide use over recent decades has been a global concern. Pollinators like bees and butterflies support both wild plants and agricultural food production, but many ...
Oryza rufipogon is an ordinary-looking wild grass found today in parts of China, India and Southeast Asia. More than 8,000 years ago, people living in the Lower Yangtze Valley began cultivating it.
"Photo 51" was a cleaner version of an earlier X-ray image, "Photo 49," that Rosalind Franklin had already used to calculate key features of DNA, challenging long-held assumptions about her role in the discovery of the double ...
Much of what scientists know about how genetic differences affect health comes from studying populations outside Africa. This matters because genetic information is increasingly being used to understand disease, interpret ...
Scientists have long sought to understand the complex origins of intelligent life. It remains unclear how biological systems not only formed but survived and persisted under the extreme conditions of primordial Earth's hostile ...
Giardia duodenalis is a microscopic, flagellated parasite that often calls the human and animal gut its home. In most cases, it coexists harmlessly with its host, and most infected pets and people show no signs of illness. ...
