The production of new myelin in the brain—a function of non-neuronal glial cells—may be necessary for motor learning, a mouse study shows.

GENETICS publishes a commentary criticizing a Nature Neuroscience paper claiming that mice can inherit smell sensitivities that their parents acquired during life.

The brain’s ability to make new neural connections can be restored in mice by blocking a protein that normally acts as a natural brake on neuroplasticity. 

Genes acquired from bacteria contributed to the origins of archaeal lineages, a large-scale phylogenetic analysis suggests.

Rediscovery of a snail thought to be extinct has raised questions about the peer-review process that approved the publication of the extinction report.

The Scientist speaks with W.E. Moerner, who last week shared the Nobel Prize in Chemistry for his work on super-resolution molecular imaging.

Use of a veterinary painkiller, banned in several countries because of its lethal effects on scavenging birds, has declined, but cow carcasses still test positive.

Researchers have sequenced 360 varieties of the tomato plant to create a comprehensive map of the evolution of the fruit from its wild form to the modern varieties. 

Mitochondrial mutations inherited from the mother can shorten a mouse’s lifespan.

Eric Betzig, Stefan Hell, and William Moerner have won the 2014 Nobel Prize in Chemistry "for the development of super-resolved fluorescence microscopy."

In order to make the most of biomedical research funding and to better support trainees, institutions should recognize postdocs as employees.

John O’Keefe, May-Britt Moser, and Edvard Moser have won the 2014 Nobel Prize in Physiology or Medicine “for their discoveries of cells that constitute a positioning system in the brain.”
