The radula sounds like something from a horror movie — a conveyor belt lined with hundreds of rows of interlocking teeth. In fact, radulas are found in the mouths of most molluscs, from the giant squid to the garden snail. Now, a “prototype” radula fo…

In the face of a changing climate, many species must adapt or perish. Ecologists studying evolutionary responses to climate change forecast that cold-blooded tropical species are not as vulnerable to extinction as previously thought. The study consider…

By affixing nanoscale gold spheres onto a microscopic bead of glass, researchers have created a super-sensor that can detect even single samples of the smallest known viruses. The sensor uses a peculiar behavior of light known as “whispering gallery mo…

A new study suggests that nicotinamide, more commonly known as vitamin B3, may be able to combat some of the antibiotic-resistance staph infections and “superbugs” that are increasingly common around the world, have killed thousands and can pose a sign…

Why are there so many species of beetles and so few crocodiles? The answer may be ecological limits to species number, scientists report.

DEAD-box proteins, which are ancient enzymes found in all forms of life, function as recycling “nanopistons.” They use chemical energy to clamp down and pry open RNA strands, thereby enabling the formation of new structures.

Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin? A new study pinpoints uniquely human patterns of gene activity in the brai…

Researchers have succeeded in mapping how light behaves in complex photonic materials inspired by nature, like iridescent butterfly wings. Scientists have broken the limit of light resolution at the nanoscale and delivered a fundamental insight into ho…

Uncoupling proteins present a paradox.  They are found within mitochondria and serve to prevent the cell’s powerhouses from exploiting the charge differential across their membranes to generate ATP, which the body uses as an energy source.  When un…
