Color-changing mood rings, forehead fever strips and car-shade indicators all change hues as they warm and cool, thanks to a phenomenon called thermochromism. On a smaller scale, thermochromism is used in nanotechnologies ...
Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...
Scientists have developed a new type of "virtual" metasurface—capable of controlling light in ways traditional lenses and optics can't—which they say is superior to the current approach, which relies on ultrathin engineered ...
A new method for recognizing and targeting DNA that dramatically expands the range of genetic sequences scientists can identify has been developed by experts at the University of Portsmouth. Published this week in Nature ...
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
How could we noninvasively distinguish between healthy and cancerous tissue? And how could we increase the speed of wireless communications? These two seemingly unrelated questions may share the same answer: terahertz (THz) ...
Multicellular life depends on remarkable acts of cooperation. Every cell in the human body must sense what is happening around it, interpret signals from its neighbors and respond in ways that support the larger tissue. These ...
New instruments on the horizon promise the most precise tools yet to study and experiment on the smallest and most complex materials ever manufactured. In a paper published in the journal Nature Materials, University of Cincinnati ...
Our body contains an intricate system of tiny vessels through which blood, water and other molecules flow. When the size of the pipes shrinks to the nanoscale, where only a few molecules can fit side by side, the classical ...
Tiny algae-based robots guided by magnets could improve bladder cancer treatment by boosting delivery of chemotherapy drugs into tumors, researchers say.
