The fovea centralis, or fovea for short, sits in the middle of the Macula lutea (or macula) of the retina, where the slender, funnel-like ocular cones are especially closely packed together. We see an image with greatest ...

For more than a decade, a vial of rare snake venom refused to give up its secret formula for lethality; its toxins had no effect on the proteins that most venoms target. Finally, an international team of researchers figured ...

For more than a century, scientists have understood the basics of inheritance: if good genes help parents survive and reproduce, the parents pass those genes along to their offspring. And yet, recent research has shown that ...

(Phys.org) —A 17-year old bet among scientists at the Karolinska Institute has been a wager that whoever wrote the most articles with Dylan quotes before they retired would get a free lunch. Results included papers such ...
Biochemists working at the University of California, San Diego, have developed a program that predicts the placement of chemical marks that control the activity of genes based on sequences of DNA. They describe their analysis ...
