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
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.
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
Findings Show The Force of Blood Flow Has Anti-Inflammatory Effect
Scientists have found a new way in which exercise may protect against heart disease. Increased blood flow can mimic the powerful anti-inflammatory actions of certain glucocorticoid steroid drugs, according to researchers at the University of Pennsylvanias Institute for Medicine and Engineering. The researchers discovered that an increase in shear stress – the drag force exerted by blood flowing over endothelial
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
Teenagers who say their parents restrict their television viewing of certain programs are likely to watch the restricted shows at friends’ houses, a study suggests.
These teens also reported less positive attitudes toward their parents, according to the research.
“Unfortunately, parents’ good intentions in restricting television viewing may actually backfire and contribute to them watching more of the programs they shouldn’t see,” said Amy Nathanson, author of the study and assista
