Study shows lizard moms dress their children for success
...ities, the aggressive orange-throated males are so busy fighting with other lizards that they are especially vulnerable to predators. As a result, the predators are likely to focus on them, giving a survival advantage to lizards with different patterns. After Lancaster released the lizards from her bree...Cellular message movement captured on video

Borrell thinks this may be because the rewards at these flowers can be tremendous, up to ten times the quanity of nectar provided by typical bee flo......d that our brains fend off distractions. If we are busy with something we suppress disrupting external influences. If we are tired, we can no longer do this.

With its 100 busy enzymes, the entire genome had to be observed as a whole, since fiddling with combinations of two, three, or more enzymes at a time would have taken "more than our lifetime," Wu says.

...void overshooting and ending up in the middle of a busy intersection," Fortune said. "Your brain has to do this all the time when controlling movement because your body and limbs, like a car, have mass.

A field of spring wildflowers, abuzz with busy insects seeking nectar and spreading pollen, may look like a perfect model of random interaction. But ecologists have discovered order within this anarchy. For instance, as the number of species grows, the number of interactions does too, while the c...Bumblebee house warming -- it takes a village
All bumblebees always aren't as busy as, well, a bee. It all depends on what their job is. Researchers have known that a key to the insects' success in adapting to cooler climates is their ability to maintain fairly stable body temperatures when flying to flowers. Whether and how the...Roadworks on the motorways of the cell
A cell is a busy place. In a permanent rush hour, molecules are transported along a dynamic motorway system made up of filaments called microtubules. Microtubules constantly grow and shrink and are rapidly assembled wherever a cargo needs to go, but during this trans...Study reveals noisy Christmas toys can damage hearing
