Using fish bred at Washington State University, an international team of researchers has mapped the genetic profile of the rainbow trout, a versatile salmonid whose relatively recent genetic history opens a window into how vertebrates evolve.

Mice are nocturnal. When both wild type and Chrono knockout mice are kept in an environment with 12 hours of light (blue) and 12 hours of dark (white).They align their...
Over the last few decades researchers have characterized a set of clock genes that drive daily rhythms of physiology and behavior in all types of species, from flies to humans. Over 15 mammalian clock proteins have been identified, but researchers surmise there are more. A team from the Perelman School of Medicine at the University of Pennsylvania wondered if big-data approaches could find them.

This shows the female penis of N. aurora.
Researchers reporting in the Cell Press journal Current Biology on April 17 have discovered little-known cave insects with rather novel sex lives. The Brazilian insects, which represent four distinct but related species in the genus Neotrogla, are the first example of an animal with sex-reversed genitalia.

This shows active droplets.
Droplets of filamentous material enclosed in a lipid membrane: these are the models of a "simplified" cell used by the SISSA physicists Luca Giomi and Antonio DeSimone, who simulated the spontaneous emergence of cell motility and division - that is, features of living material - in inanimate "objects". The research is one of the cover stories of the April 10th online issue of the journal Physical Review Letters.

Here are Cian O'Donnell and Terry Sejnowski.
Scientists at the Salk Institute have created a new model of memory that explains how neurons retain select memories a few hours after an event.

Mitochondria in hepatitis C-infected cells (bottom row) are self-destructing. The self-annihilation process explains the persistance and virulence of the virus in human liver cells.
Researchers at the University of California, San Diego School of Medicine have identified a mechanism that explains why people with the hepatitis C virus get liver disease and why the virus is able to persist in the body for so long.

This shows Hadza women roasting tubers.
The gut microbiota is responsible for many aspects of human health and nutrition, but most studies have focused on "western" populations. An international collaboration of researchers, including researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has for the first time analysed the gut microbiota of a modern hunter-gatherer community, the Hadza of Tanzania. The results of this work show that Hadza harbour a unique microbial profile with features yet unseen in any other human group, supporting the notion that Hadza gut bacteria play an essential role in adaptation to a foraging subsistence pattern. The study further shows how the intestinal flora may have helped our ancestors adapt and survive during the Paleolithic

Splicing variants (red) of autism genes were cloned from the brain and screened for interactions. The image on the right represents the network of interactions.
A team of researchers from the University of California, San Diego School of Medicine and the Center for Cancer Systems Biology (CCSB) at the Dana-Farber Cancer Institute has uncovered a new aspect of autism, revealing that proteins involved in autism interact with many more partners than previously known. These interactions had not been detected earlier because they involve alternatively spliced forms of autism genes found in the brain.

The 375 million-year-old fossil lycopod Leclercqia scolopendra, described and beautifully rendered by UC Berkeley graduate student Jeffrey Benca.
Jeff Benca is an admitted über-geek when it comes to prehistoric plants, so it was no surprise that, when he submitted a paper describing a new species of long-extinct lycopod for publication, he ditched the standard line drawing and insisted on a detailed and beautifully rendered color reconstruction of the plant. This piece earned the cover of March's centennial issue of the American Journal of Botany.

New research from scientists at the University of Massachusetts Medical School shows that fruit flies are secretly harboring the biochemistry needed to glow in the dark —otherwise known as bioluminescence.
