In studies with monkeys, researchers have identified in detail the brain regions responsible for the unique ability of primates, including humans, to process visual 3D shapes to guide their…

I have previously commented on how organic chemistry can be incorporated into Second Life. Andrew Lang has created a script to generate 3D structures of molecules and shown how to represent the…

A woman, whose ovaries had failed due to damage caused by chemotherapy and radiotherapy, has received a successful ovarian transplant from her genetically non-identical sister. The transplant…

Forsyth Institute scientists have discovered an important mechanism for controlling the behavior of adult stem cells. Research with the flatworm, planaria, found a novel role for the proteins…

Stars don’t shine forever. How long a star lives depends on how big and heavy it is. The bigger the star, the shorter its life. When a star significantly heavier than our sun runs out of fuel, it…

Scientists from the Animal Ecology and Cell Biology Institute of the University of Veterinary Medicine Hannover were able to develop a many-headed jellyfish when Cnox genes were deactivated. These…

Disorders of arousal (i.e., sleepwalking, confusional arousals and sleep terrors) have sometimes been associated with violent behaviors against other individuals. A preliminary review of possible…

The concept of the memory of water goes back to 1988 when the late Professor Jacques Benveniste published, in the international scientific journal Nature, claims that extremely high ‘ultramolecular’…
