Genetic study shakes up the elephant family tree

New research reveals that a species of giant elephant that lived 1.5 million to 100,000 years ago - ranging across Eurasia before it went extinct - is more closely related to today's African forest elephant than the forest ...

Genetic mutation trade-offs lead to parallel evolution

Organisms in nature adapt and evolve in complex environments. For example, when subjected to changes in nutrients, antibiotics, and predation, microbes in the wild face the challenge of adapting multiple traits at the same ...

How plants tell time

Findings of a new study solve a key mystery about the chemistry of how plants tell time so they can flower and metabolize nutrients.

Titan supercomputer analyzes bacterial photosynthetic system

Despite the grand diversity among living organisms, the molecule used to store and transmit energy within aerobic, or oxygen-using, cells is remarkably the same. From bacteria to fungi, plants, and animals, adenosine triphosphate ...

Cancer-causing virus masters cell's replication, immortality

Viruses are notorious for taking over their host's operations and using them to their own advantage. But few human viruses make themselves quite as cozy as the Epstein-Barr virus, which can be found in an estimated nine out ...

For a green alga, spotted salamanders are stressful hosts

New research shows how two drastically different organisms—a green alga and the spotted salamander—get along as cellular roommates. Scientists at the American Museum of Natural History and Gettysburg College found that ...
