Bee

A new study shows that exposure to high temperatures adds up to 14 months to older adults' cellular age.

The field’s failure to integrate medical services in the mid-20th century set the stage for its current troubles.

As far as animals go, honey bees are world-class dancers.

While not as deep and complex as a Super Bowl half-time show, the bees' moves, known as the “waggle" dance, convey very specific food foraging instructions to their nestmates. The direction the dancer moves explains to other bees which way to go, and the duration of the waggle dance, or the “run,” shows how far to go. Once other bees have been convinced to follow the directions, they are “recruited.” After receiving the instructions, these recruits leave the hive to find the food their sisters were so excited about.

• Tiny electrodes placed precisely in the brain let people with spinal cord injuries feel sensations of shape, motion, and the orientation of objects on the skin.
• Coupled with further advances in bionic limbs, such technology could eventually help provide an artificial sense of touch.
