Food Can Affect A Cell In The Same Way Hormones Do:

VIB researchers connected to the Katholieke Universiteit Leuven have discovered an important new mechanism with which cells can detect nutrients. This happens in the same way - and with the same effects - as when cells receive a message from a hormone. This finding can teach us more about how food affects our body; and, furthermore, it can form the basis for new candidate targets for medicines.

Climate Change Wiped Out Cave Bears 13 Millennia Earlier Than Thought:

Enormous cave bears, Ursus spelaeus, that once inhabited a large swathe of Europe, from Spain to the Urals, died out 27,800 years ago, around 13 millennia earlier than was previously believed, scientists have reported.

Cell Movements Totally Modular, Study Shows:

A study describing how cells within blood vessel walls move en masse overturns an assumption common in the age of genomics -- that the proteins driving cell behavior are doing so much multitasking that it would be near impossible to group them according to a few discrete functions.

Transporting Young Salmon To Help Them Avoid Dams Hinders Adult Migration:

Scientists have discovered that management efforts intended to assist migrations of salmon and steelhead trout can have unintended consequences for fish populations. Juveniles that are transported downstream on boats can lose the ability to migrate back to their breeding grounds, reducing their survivorship and altering adaptations in the wild.

Mutualism By Natural Selection: Imitation Is Not Just Flattery For Amazon Butterfly Species:

Many studies of evolution focus on the benefits to the individual of competing successfully - those who survive produce the most offspring, in Darwin's classic 'survival of the fittest'. But how does this translate to the evolution of species?

California's Deep Sea Secrets: New Species Found, Human Impact Revealed:

Scientists from Scripps Institution of Oceanography at UC San Diego returning from research expeditions in Mexico have captured unprecedented details of vibrant sea life and ecosystems in the Gulf of California, including documentations of new species and marine animals previously never seen alive.
