Researchers have long known that some repetitive DNA sequences can make human chromosomes "fragile," i.e. appearing constricted or even broken during cell divisions. Scientists at Tufts University have found that one such ...

Most cells can defend themselves against viruses after they have been activated by the body's own messenger substances (interferons). This happens with the help of proteins that recognize invading virus components and interfere ...
