Scientists pinpoint our most distant animal relatives
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.

Soft X-ray microscopy shows how viral pathogens penetrate human cells
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"

Although not venemous, a mouse's bite holds venomous potential
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

Prime editing enables precise gene editing without collateral damage
The latest gene editing technology, prime editing, expands the 'genetic toolbox' for more precisely creating disease models and correcting genetic problems, scientists say.

Scientists identify molecular pathway that helps moving cells avoid aimless wandering
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

HSV-1 infection induces strain-specific transcriptional differences in infected neurons
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.

Differences in herpes virus symptoms may relate to variations in strain gene expression
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 finds that these differences could be due to variations in the way certain strains of herpes simplex (HSV-1) -- the virus that causes cold

Antibody for uterine sensitization associated gene-1 can stimulate tooth growth in mice
The tooth fairy is a welcome guest for any child who has lost a tooth. Not only will the fairy leave a small gift under the pillow, but the child can be assured of a new tooth in a few months. The same cannot be said of adults who have lost their teeth.

Cells rely on their crampons to avoid slipping
Scientists have highlighted the key role of a protein called paxillin, which enables cells to perceive their environment and anchor at the right place with the help of cellular 'crampons'. Indeed, without functional paxillin, the cell is unable to attach properly and slips continuously. These
