Chemists create nanofibers using unprecedented new method

Researchers from Carnegie Mellon University have developed a novel method for creating self-assembled protein/polymer nanostructures that are reminiscent of fibers found in living cells. The work offers a promising new way ...

A silky spin on protective armor

At seven times the toughness of Kevlar, a silk produced by the Caerostris darwini spider of Madagascar is more robust than any other material—synthetic or natural. Most spider silks are about two times tougher than Kevlar, ...

Axons' unexpected cytoskeleton structure

(Phys.org)—The plasma membranes that give cells their shapes are typically upheld by linear meshworks of the protein actin. In contrast, Howard Hughes Medical Institute scientists have now discovered that periodic ring-shaped ...

Ractopamine is safe for use in Brazilian pork

Animal scientists in Brazil have found that a small dose of the feed additive ractopamine can boost pork production without changing how pork looks or tastes.

Lizard tails detach at a biological 'dotted line'

Like sheets of paper marked with perforated lines, gecko tails have unique structural marks that help them sever their tails to make a quick getaway. Though voluntarily shedding a body part in this manner is a well-known ...

Hagfish slime as a model for tomorrow's natural fabrics

Nylon, Kevlar and other synthetic fabrics: Step aside. If new scientific research pans out, people may be sporting shirts, blouses and other garments made from fibers modeled after those in the icky, super-strong slime from ...

Kittens: Their microbiomes are what they eat

For animals as well as people, diet affects what grows in the gut. The gut microbial colonies, also known as the gut microbiome, begin to form at birth. Their composition affects how the immune system develops and is linked ...
