Biologists have revealed a hidden code that determines the expression level of a gene, providing a way to distinguish efficient genes from inefficient ones. The research involved creating hundreds of synthetic green-glowing genes and provides an explanation for how a cell “knows” how much of each protein to make.

Older people can dance their way towards improved health and happiness, according to new research that reveals the social, mental and physical benefits of social dancing for older people. It suggests that dancing staves off illness, and even counteracts decline in aging.
In children with vascular birthmarks around the eye, even partial blockage of vision can lead to visual loss due to amblyopia. Now a simple test can detect early evidence of amblyopia in infants too young for conventional vision testing, reports a study in the April issue of the American Journal of Ophthalmology.
The first mirror segment that will fly on the James Webb Space Telescope has completed its first series of cryogenic temperature tests in the X-ray and Cryogenic Facility at the Marshall Space Flight Center in Huntsville, Ala.

In the classic waterfall illusion, if you stare at the downward motion of a waterfall for some period of time, stationary objects — such as rocks — appear to drift upward. Neuroscientists have found that this phenomenon, called motion aftereffect, occurs not only in our visual perception but also in our tactile perception, and that [...]

Scientists have discovered a naturally occurring compound that triggers a plant’s immune system, protecting it from infection. The patent-pending discovery could lead to an effective, inexpensive and environmentally safe way to improve plants’ resistance to disease. Although it has long been known that plants have immune systems, how they has been studied intensely. This study [...]
