A simple test developed at Washington State University could eventually allow astronauts and others in round-the-clock occupations to monitor their biological rhythms in just minutes using a drop of blood, a paper test strip, ...
There is a tiny cyclops among your oldest ancestors, and humans share these remarkable ancestral roots with all other vertebrates. Researchers from Lund University and University of Sussex have found that all vertebrates ...
Light helps us wake up, keeps us alert, and guides our sleep. But what happens when light becomes erratic? As a researcher studying molecular biology and animal stress responses, I've been fascinated by how environmental ...
We see color because photoreceptor cones in our eyes detect light waves corresponding to red, green, and blue, while dimness or brightness is detected by photoreceptor rods. Many non-mammalian vertebrates like fish, however, ...
Using the lamprey, researchers from Japan analyzed the photosensory mechanism of the pineal organ, also called the pineal gland, in non-mammalian vertebrates and discovered a novel mechanism of pineal color discrimination ...
When zebrafish lack a specific protein, the two hemispheres of the brain develop symmetrically, and the sleep hormone melatonin is not produced. These results were recently published by Freiburg biologists Theresa Schredelseker ...
Researchers reporting in Current Biology on April 2 have evidence that an extinct species of monitor lizard had four eyes, a first among known jawed vertebrates. Today, only the jawless lampreys have four eyes.
Lizards have special superpowers. While birds can regrow feathers and mammals can regrow skin, lizards can regenerate entire structures such as their tails. Despite these differences, all have evolved from the same ancestor ...
Animals need to measure the time of year so that they can anticipate and adapt to the arrival of a new season to align reproduction, as well as other vital functions critical for survival. A new study, conducted at the University ...
French philosopher René Descartes believed that the pineal gland, a tiny button of neurons located in the depth of our brain, was the seat of the soul.
