Dwarfism gene linked to protection from cancer and diabetes

A 22-year study found no cases of diabetes and only one non-lethal case of cancer in individuals with Laron syndrome, a growth-stunting mutation. In contrast, relatives without such mutations had higher rates of diabetes and cancer. The study suggests that blocking growth hormone activity may be protective against these diseases.

The innovative treatment uses multi-sensory virtual reality to safely access and process traumatic memories.

Waking up is hard to do

Researchers found that the 'twenty-four' gene is critical for producing a key clock protein in fruit flies. Without this gene, flies experience disrupted sleep-wake rhythms and have trouble waking up. The findings suggest a similar mechanism may be at play in humans.

Xenacoelomorpha -- a new phylum in the animal kingdom

International team of scientists has discovered a new phylum, Xenacoelomorpha, which rewrites the evolutionary history of animals.
