(PhysOrg.com) -- The power and resolution of lens-based optical microscopes have improved by orders of magnitude since their invention around 1595. Nevertheless, relying on a high-magnification lens for image clarity has ...
UCLA chemists for the first time have employed magnetic resonance imaging (MRI)—a technique normally reserved for medical clinicians peering inside the human body—to better measure the temperature of gases inside a catalytic ...

(PhysOrg.com) -- A Harvard University chemistry professor is aiming to produce a blood analyzer for the developing world that will be the size of a human fingerprint, and will cost around a penny.
Johns Hopkins engineers are using a popular children's toy to visualize the behavior of particles, cells and molecules in environments too small to see with the naked eye. These researchers are arranging little LEGO pieces ...
