Electrostatic actuators are simple and lightweight devices that emulate human muscles. However, their usage has primarily been restricted to moving small devices since they need high voltages to generate significant forces. ...
Scientists in Japan have made a tuneable, elastic and temperature-sensitive gel by using complementary DNA strands to connect star-shaped polymer molecules together. The gel, and the method used to develop it, could lead ...
Researchers from Tokyo Metropolitan University have discovered how the sponginess and stickiness of stem cell nuclei controls how they "differentiate" into specialized cells. They found that the nucleus starts solid-like ...
Liquid droplets of protein and RNA have traits reminiscent of a childhood joy: Silly Putty.
Over the past few decades, some physicists worldwide have been trying to use the second layer of 4He films adsorbed on a graphite substrate to study the interplay between superfluid and supersolid phases of matter. Some teams ...
New research led by Georgia Tech's College of Engineering finds that honey bees have developed a way to transform pollen particles into a viscoelastic pellet, allowing them to transport pollen efficiently, quickly, and reliably ...
Squirting a jet of water through a drop of liquid may sound like idle fun, but if done precisely, and understood thoroughly, the splashy exercise could help scientists identify ways to inject fluids such as vaccines through ...
Arrays of metal electrodes are often used in medical procedures that require monitoring or delivering electrical impulses in the body, such as brain surgery and epilepsy mapping. However, the metal and plastic materials that ...
If you've ever tried to lift a pizza slice covered in hot, melted cheese, you've no doubt encountered the long, cheesy strings that bridge one pizza slice from the next. Keep lifting the pizza slice and these cheese bridges ...
Researchers at Aalto University have found strong evidence that warm ice—that is, ice very close in temperature to zero degrees Celsius—may fracture differently as compared to the kinds of ice typically studied in laboratories ...
