Tiny particles in air pollution have been associated with cardiovascular disease, which can lead to premature death. But how particles inhaled into the lungs can affect blood vessels and the heart has remained a mystery. Now, scientists have found evidence in human and animal studies that inhaled nanoparticles can travel from the lungs into the bloodstream, potentially explaining the link between air pollution and cardiovascular disease. Their results appear in the journal ACS Nano.

Nanodiamonds - synthetic industrial diamonds only a few nanometers in size - have recently attracted considerable attention because of the potential they offer for the targeted delivery of vaccines and cancer drugs and for other uses. Thus far, options for imaging nanodiamonds have been limited. Now a team of investigators based at the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital has devised a means of tracking nanodiamonds noninvasively with magnetic resonance imaging (MRI), opening up a host of new applications. They report their findings today in the online journal Nature Communications.

Despite their potential, the practical use of Li-O2 batteries is seriously limited by the corrosion of Li metal by ambient water vapor from air. One way to circumvent this issue is to use an oxygen selective membrane that allows only oxygen into the battery while stopping or slowing water vapor intake. The membrane must be mechanically robust and yet sufficiently thin and light so as to not increase deadweight of the battery. Researchers now have discovered a way to make the thinnest possible oxygen selective membrane using graphene.
