- Switching Senses
New findings reveal that, in blind people, areas of the brain that would normally process visual information do not simply pack up and disappear; instead, they find new work processing language-related information,
- Altered Chromosome Number As Cause Of Cancer
Study identifies a role for whole chromosome losses or gains (known as aneuploidy) as a causal event in cancer.
