New program simulates protein movements

Proteins are molecules involved in most of the biological processes that take place in our bodies. They have to move in order to fulfil many of their functions. For example, they open or close to keep and transport the molecules ...

Building protocells from inorganic nanoparticles

(Phys.org) —Researchers at the University of Bristol have led a new enquiry into how extremely small particles of silica (sand) can be used to design and construct artificial protocells in the laboratory. The work is described ...

Hormonal birth control alters scent communication in primates

Hormonal contraceptives change the ways captive ring-tailed lemurs relate to one another both socially and sexually, according to a Duke University study that combined analyses of hormones, genes, scent chemicals and behavior.

Making microscopic machines using metallic glass

Researchers in Ireland have developed a new technology using materials called bulk metallic glasses to produce high-precision molds for making tiny plastic components. The components, with detailed microscopically patterned ...

Lipid expansion microscopy uses 'power of click chemistry'

Lipids—fats—make great walls for cells and organelles because they are water resistant and dynamic. But those same characteristics also make them hard to image using expansion microscopy, a technique that works for magnifying ...
