Scientists believe they have pinpointed our most distant animal relative in the tree of life and, in doing so, have resolved an ongoing debate. Their work finds strong evidence that sponges - not more complex comb jellies - were our most distant relatives.
How do viral pathogens succeed in penetrating human cells? Which cellular mechanisms do they use to multiply efficiently and, in doing so, how do they change the structure of their host cell? These questions are the focus of a pan-European research project called "Compact Cell-Imaging Device"
Washington State University researchers have discovered a protein that could be key to blocking the most common bacterial cause of human food poisoning in the United States.

We are not venomous, and neither are mice - but within our genomes lurks that potential, suggest scientists The researchers found that the genetic foundation required for oral venom to evolve is present in both reptiles and mammals. The study also provides the first concrete evidence of an
The latest gene editing technology, prime editing, expands the 'genetic toolbox' for more precisely creating disease models and correcting genetic problems, scientists say.
Working with fruit flies, scientists say they have identified a new molecular pathway that helps steer moving cells in specific directions. The set of interconnected proteins and enzymes in the pathway act as steering and rudder components that drive cells toward an 'intended' rather than random
Scientists have identified the protein that was the missing evolutionary link between two ancient algae species - red algae and cryptophytes.
Why do some people with cold sores around their lips experience painful lesions, while others have no symptoms at all, yet still spread the virus? A new study conducted at Penn State finds that these differences could be due to variations in the way certain strains of herpes simplex (HSV-1) -- the

Plants remember drought

During drought, plants use a signalling molecule known from animals to limit their water loss. The molecule provides them with a kind of memory of how dry the day was.
