Neural circuits that control eye movements play multiple roles in visual attention

With so many visual stimuli bombarding our eyes — cars whizzing by, leaves fluttering — how can we focus attention on a single spot — a word on a page or a fleeting facial expression? How do we filter so purely that the competing stimuli never even register in our awareness?

A pair of Princeton scientists have found that it has a lot to do with the brain circuits that control eye movements.

In an organic chemistry lab located in the Science II building on the campus of Binghamton University, Scott Handy is busy whipping up promising new substances modeled after natural compounds found in sea sponges and tobacco plants. Some of the synthetic compounds could help in the fight against cancer and AIDS. Others could provide a safer, more effective, and more affordable alternative to the traditional solvents organic chemists use to catalyze reactions and synthesize compounds, one molecule at

A vaccine aimed against AIDS, developed at the Yerkes National Primate Research Center of Emory University, the Emory Vaccine Center, and the Laboratory of Viral Diseases at the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institutes of Health (NIH), will begin a Phase I clinical trial this week.

A total of 30 human volunteers will be enrolled at the University of Alabama at Birmingham, the University of Washington in Seattle, and the San Francisco Departmen

Findings point to complex social behaviour

The large tusks of an animal that roamed Earth before the dinosaurs may provide the earliest evidence yet of male-female distinctions in land animals that existed millions of years ago, say U of T scientists.

Robert Reisz, a biology professor at the University of Toronto at Mississauga, and his team have found convincing evidence of sexual dimorphism – different physical traits between the sexes of the same species – in their study

Scientists at the San Diego Supercomputer Center (SDSC) at UCSD analyzing traffic to one of the 13 Domain Name System (DNS) “root” servers at the heart of the Internet found that the server spends the majority of its time dealing with unnecessary queries. DNS root servers provide a critical link between users and the Internet’s routing infrastructure by mapping text host names to numeric Internet Protocol (IP) addresses.

Recent research shows that insects and humans have something surprising in common: Some six-legged species take in oxygen using a similar means to the way we fill our lungs.

Scientists from the Field Museum and Argonne National Laboratory in Chicago and from Clemson University used a powerful x-ray imaging device to get the first comprehensive view of live insects breathing. Their observations and research results are reported in the Jan. 24 issue of Science, an internationally respected res
