Materials scientists at UNSW Sydney have shown that human pluripotent stem cells in a lab can initiate a process resembling the gastrulation phase—where cells begin differentiating into new cell types—much earlier than ...
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 ...
Artificial surfaces that can repel liquids have attracted significant attention across scientific and industrial platforms to create functional topological features. But the role of the underlying structures that are in contact ...
College students have used it to make cheap furniture, China has had shortages of it, and main character Michael Scott of "The Office" once famously buried his face in it. Concrete is everywhere—a ubiquity owed to its strength ...
The shearing of fluids—meaning the sliding of fluid layers over each other under shear forces—is an important concept in nature and in rheology, the science that studies the flow behavior of matter, including liquids ...
A University of Virginia-led study about a class of materials called associative polymers appears to challenge a long-held understanding of how the materials, which have unique self-healing and flow properties, function at ...
Scientists from the University of Tsukuba obtained a new theoretical equation for the propagation of ultrasonic waves through liquids containing encapsulated bubbles. They found that including the compressibility of the bubble ...
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. ...
It can be observed every time you take a shower: Small droplets of water join together to form larger and larger drops—until they are so heavy that they run down the wall. Scientists call this daily-life phenomenon coalescence—which ...
Blood spatters are hydrodynamic signatures of violent crimes, often revealing when an event occurred and where the perpetrator and victim were located at the time of the crime.
