Living organisms adapt their behavior and movements based on information they acquire from their surrounding environment. But oftentimes this information is imperfect, and the organism needs to act under uncertainty. So, ...
Bioinspired materials are designed and engineered to mimic the biological functions of nature; however fast actuation is an important but challenging task to recreate in the lab. In a recent study, Wenxin Fan and co-workers ...
Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses. These structures can control ...
(Phys.org)—In a new study, scientists have proposed that tiny residual effects measured by ether-drift experiments in the 1920s and '30s may be the first evidence of a temperature gradient that was theorized in the 1970s, ...
(Phys.org)—Scientists have demonstrated that pinwheel-shaped microgears floating on a liquid surface can rotate at speeds of up to 300 r.p.m. when illuminated by an ordinary LED. This light-driven motion, which arises because ...
(Phys.org) —The ability to make measurements of the biomolecular interactions that occur inside living cells is essential for understanding complex biological processes. But probing the inside of living cells without damaging ...
(Phys.org)—The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new ...
(PhysOrg.com) -- In an attempt to develop a power source that is compact, environmentally friendly, and has an unlimited lifetime, a team of researchers from Singapore has fabricated an energy harvesting device that generates ...
The potential to isolate and regulate the biodynamics of single cells is significant in drug design and screening. However, pre-existing experimental reports in single-cell drug screening must yet provide multiple-dose gradient ...
Researchers from North Carolina State University and the University of North Carolina at Chapel Hill used chiral phonons to convert wasted heat into spin information—without needing magnetic materials. The finding could ...
