Deploying therapeutic nano-payloads to cells

Researchers create a huge variety of programmed three-dimensional shapes out of single strands of synthetic DNA, a process known as DNA origami. These nanoparticles may ultimately be deployed as structural scaffolds to deliver vaccines, drugs, or even gene-editing tools such as CRISPR-Cas9 to specific parts of the body, he says.

Strong hydrogels that respond to force, heat and light

Novel hydrogels not only exhibited remarkable optical response from pale yellow to purple color and from green to red fluorescence under external stimuli of force, heat, and UV light, but also simply reversed its color back to the original one by white light.

Breaking Newton's Law

In the quantum world, our intuition for moving objects is strongly challenged and may sometimes even completely fail. Experimental physicists have found a quantum particle which shows an intriguing oscillatory back-and-forth motion in a one-dimensional atomic gas.

Locked movement in molecular motor and rotor

For a motor to power machinery, the local motion has to be translated into the ordered movement of other parts of the system. Organic chemists have now achieved this in a molecular motor.
