Parasite that replaces a fish's tongue caught at Texas state park
An unknown person working at Galveston Island Sate Park, Texas Parks and Wildlife, has posted a picture of a unique fish that was caught at the park on Facebook—it has no natural tongue. Instead, it has a tongue made up of a group of parasites known as a tongue-eating louse. In the picture, the fish is held up to the camera with its mouth wide open showing the strange foreign 'tongue' inside.

Establishing the universality of quantum dynamics is one of the key interests of theoretical physicists. Now, researchers from Japan have identified such a universality in disordered quantum systems, characterized by a one-parameter scaling for surface roughness and entanglement entropy (a measure of

Friend or Foe? Single Neurons in the Brain Control Social Interaction, Study Finds
Neurons live in a society, and scientists just found the ones that may allow us to thrive in our own society. Like humans, individual neurons are strikingly unique. Also like humans, they're constantly in touch with each other. They hook up into neural circuit "friend groups," break apart when things change, and rewire into new cliques. This flexibility lets their collective society (the brain) a

What really makes fish become sexually active
Discounting anthropogenic-induced changes, the seasonally oscillating environments where long-lived fish hatch and grow remain more or less the same throughout the course of their lives.

Effect of small polyanions on retroviruses
A retrovirus is a virus that inserts a copy of its genome into the DNA of a host cell that it invades, thus changing that cell's genome. Once inside the host cell's cytoplasm, the virus uses its reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro. The host cell then treats the viral DNA as part of its genome, transcribing and translating th
