Researchers create most complete model of complex protein machinery

Environmental conditions, lifestyle choices, chemical exposure, and foodborne and airborne pathogens are among the external factors that can cause disease. In contrast, internal genetic factors can be responsible for the ...

Thick-skinned bed bugs beat commonly used bug sprays

The global resurgence in bed bugs over the past two decades could be explained by revelations that bed bugs have developed a thicker cuticle that enables them to survive exposure to commonly used insecticides, according to ...

Humidity makes gecko feet stickier

Geckos have amazingly sticky feet. Their stickability comes from billions of dry microscopic hairs that coat the soles of their feet. However, when humidity increases, gecko feet stick even tighter to smooth surfaces, so ...

Quantum microscope for living biology

(Phys.org)—A team of Australian scientists has developed a powerful microscope using the laws of quantum mechanics to probe the inner workings of living cells.

True colors: Female squid have two ways to switch color

The female common market squid –– AKA Doryteuthis opalescens –– may not be so common after all. Researchers at UC Santa Barbara have discovered that this glamorous cephalopod possesses a pair of stripes that can sparkle ...

The secret behind spectacular blooms in world's driest desert

The Atacama desert, which stretches for approximately 1,600 km along the western coast of the cone of South America, is the driest place on Earth. Some weather stations there have never recorded rainfall throughout their ...

Bionic bacteria may help fight disease and global warming

A strain of genetically enhanced bacteria developed by researchers at the Salk Institute for Biological Studies may pave the way for new synthetic drugs and new ways of manufacturing medicines and biofuels, according to a ...

Lactating tsetse flies models for lactating mammals?

An unprecedented study of intra-uterine lactation in the tsetse fly, published 18 April 2012 in Biology of Reproduction's Papers-in-Press, reveals that an enzyme found in the fly's milk functions similarly in mammals, making ...

Le Rouge et le Noir: Where the black dahlia gets its color
