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
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
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.

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.
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
Hola, soy alumno de doctorado y desarrollo mi proyecto con el Dr Iván Velasco en el IFC. Me gustaría saber si alguien trabaja con líneas de microglía humana, que pudiera hacernos una donación de estas células ya sea CHME o cualquier otra. Agradecería mucho su apoyo. Saludos. Juan Jair
