Optogenetics uses light to control brain processes. It is based on light-controlled proteins such as channelrhodopsin-2, an ion channel that opens when it's exposed to light, thus activating cell..

A new study confirms that a simple blood test can reveal whether there is accelerating nerve cell damage in the brain. The researchers analyzed neurofilament light protein (NFL) in blood samples from ..

Our actions are driven by 'internal states' such as anxiety, stress or thirst — which will strongly affect and motivate our behaviors. Little is known about how such states are represented ..

Researchers demonstrate that genetically identical cells exhibit differing responses in their motility towards chemical attractants. Average values hide the full picture when it comes to describing th..

There appears to be an underlying selection mechanism at work among Gouldian finches — a mechanism that allows this species to produce and maintain individuals with red heads, black heads, and yellow..

A biologist invented an inexpensive and environmentally friendly method for making artificial nacre using an innovative component: bacteria. The artificial nacre is made of biologically produced mater..

New research on tube anemones is challenging everything that evolutionary biologists thought they knew about sea animal genetics. The mitochondrial DNA of the tube anemone, or Ceriantharia, is a real ..

In the past decade, knowledge of how lifestyle affects our genes, a research field called epigenetics, has grown exponentially. Researchers have summarized the state of scientific knowledge within epi..

A new study of adults who were referred for evaluation of a suspected sleep disorder suggests that women tend to underreport snoring and underestimate its loudness.

The discovery of dozens of pregnant giant devil rays tangled in fishing nets in a village along Mexico's Gulf of California could mean the endangered species has a previously unknown birthing zon..
