A known environmental hazard can change the epigenetics of cells

Epigenetics, the chemical mechanisms that control the activity of genes, allows our cells, tissues and organs to adapt to the changing circumstances of the environment around us. This advantage can become a drawback, though, ...

Carbon nanotube composites for enzymes and cosmetics

Japanese researchers have developed a low cost and efficient method for producing electrically conducting composites based on electrostatic adsorption of CNTs onto resin and ceramic particles for applications including enzymes ...

Lungs may suffer when certain elements go nano

(Phys.org) —Nanoparticles are used in all kinds of applications—electronics, medicine, cosmetics, even environmental clean-ups. More than 2,800 commercially available applications are now based on nanoparticles, and by ...

Brown algae reveal antioxidant production secrets

Brown algae contain phlorotannins, aromatic (phenolic) compounds that are unique in the plant kingdom. As natural antioxidants, phlorotannins are of great interest for the treament and prevention of cancer and inflammatory, ...

Researchers electrify polymerization

Scientists led by Carnegie Mellon University chemist Krzysztof Matyjaszewski are using electricity from a battery to drive atom transfer radical polymerization (ATRP), a widely used method of creating industrial plastics. ...
