Measuring the forces of biology

Biology, at the nitty-gritty level of motor proteins, DNA, and microtubules, takes its cue from physics. While much is known about the biological components that form the mitotic spindle, researchers are only beginning to explore the physical forces between those components.

Nano-decoy lures human Influenza A virus to Its doom

To infect its victims, influenza A heads for the lungs, where it latches onto sialic acid on the surface of cells. So researchers created the perfect decoy: A carefully constructed spherical nanoparticle coated in sialic acid lures the influenza A virus to its doom. When misted into the lungs, the nanoparticle traps influenza A, holding it until the virus self-destructs.

Talking speckles

The amount of light, passing through an opaque layer, can be enhanced using smart techniques. At the same time, the amount of reflected light diminishes, researchers now show. It's as if light speckles have a conversation of their own.

New materials with photonic crystals that filter radiation

Researchers have proposed various designs of materials of a photonic crystal type that can be used to filter radiation. Specifically, the focus has been to develop a coating comprising dielectric spheres which if applied to a window, for example, would prevent the outside heat entering in the summer and the indoor heat from escaping in winter.
