(PhysOrg.com) -- Scientists know that cancerous cells and normal cells have different physical features, but the details of these differences, and why they occur, are not well understood. In a recent edition of Nature Nanotechnology, ...
(PhysOrg.com) -- Devices that harvest ambient energy from the surrounding environment have become popular since, for some applications, they eliminate the need for batteries that must constantly be replaced. One of the most ...
(PhysOrg.com) -- By using light to change the elasticity of a DNA molecule, scientists have designed a molecular motor that can turn light into mechanical work. Unlike most previously reported molecular motors, the proposed ...
Looking for life on other planets is not straightforward. It usually relies on chemical detection, which might be limited or even completely irrelevant to alien biology. On the other hand, motion is a trait of all life, and ...
