Strategies to make lab animals forget, remember, or experience false recollections probe how memory works, and may inspire treatments for neurological diseases.

Adult neurogenesis, already appreciated for its role in learning and memory, also participates in mental health and possibly even attention, new research suggests.

Blind tadpoles regain vision when new eyes are grafted onto their tails.

Microglia ingest nerve cell connections, leading to the loss of information stored in neuronal circuits.

Advances in cage design and monitoring software allow the collection of more realistic data.

Once believed to be unique to birds and mammals, sleep is found across the metazoan kingdom. Some animals, it seems, can’t live without it, though no one knows exactly why.

By Kelly Rae Chi Behavior in Action Tools and techniques for tracking mammalian behavior. Even the seemingly simplest mammalian behaviors, such as grooming one’s offspring, involve a complex series of tiny movements that may be invisible to the human eye. But in studying those behaviors, how to break them down into reliable, measurable components? “All of these advances in technology give us data that [weren’t] available

Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t

Date: February 2, 1998 Chart 1 Chart 2 Prokaryotic expression systems, reviewed in the September 1, 1997, issue of The Scientist were part of the early repertoire of research tools in molecular biology. Although the expression of recombinant protein in prokaryotes provided a means to develop other research tools (antibodies, for example ) and study basic aspects of biological function, the scope and depth of this research were limited, especially with regard to eukaryotic proteins. The de novo
