Removal of a gene could render lethal poxviruses harmless

The removal of one gene renders poxviruses—a lethal family of viral infections that are known to spread from animals to humans—harmless, a new study in the journal Science Advances reports.

How seasonal allergies affect your pet

With an uptick in pollen comes the torturous sneezing and watery eyes. Pets get seasonal allergies, too, but they exhibit discomfort in different ways.

Study gives insight into sun-induced DNA damage and cell repair

A team led by a Baylor University researcher has published a breakthrough article that provides a better understanding of the dynamic process by which sunlight-induced DNA damage is recognized by the molecular repair machinery ...

A new mechanism for accessing damaged DNA

UV light damages the DNA of skin cells, which can lead to skin cancer. But this process is counteracted by DNA repair machinery, acting as a molecular sunscreen. It has been unclear, however, how repair proteins work on DNA ...

Frog eggs help researchers understand repair of DNA damages

The DNA replication process in which cells divide to create new cells also triggers repair of DNA damage, researchers from the University of Copenhagen report in a new study. The researchers studied extracts from frog eggs, ...
