Find pushes origins back 100 million years to an ice-encased Earth
Bees have an innate tendency to form social connections. What is the origin of this social behavior? Researchers have discovered that distribution of labor, which is a feature of the social organization of bee colonies, is a result of the existence of insects specialized in aversive and appetitive responses to stimuli.

Astronomers have devised a new method for measuring the size and shape of asteroids that are too small or too far away for traditional techniques, increasing the number of asteroids that can be measured by a factor of several hundred. This method takes advantage of the unique capabilities of ESO’s Very Large Telescope Interferometer.

Researchers are trying to employ a specially designed RNA enzyme to inhibit strains of the herpes simplex virus. The enzyme disables a gene responsible for producing a protein involved in the maturation and release of viral particles in an infected cell. The technique appears to be effective in experiments with mice and rabbits.
A study of brain function in young, memory-deficient mice reveals that a stimulating environment improves not only their memory but also the memory of their memory-deficient offspring. If this improvement also occurs in humans, a mother’s youthful experiences may help shape her children’s ability to learn.
