How the "master regulators" of cells make DNA accessible for gene expression
New insight into proteins called "pioneer factors" helps to explain their unusual ability to open up the typically dense genetic material within our cells. This behavior makes the genetic material accessible for proteins involved in important cellula.....»»
What role do forests play as a feeding habitat for honeybees?
Bees are generally associated with flowering meadows rather than with dense forests. Woodland, however, is considered the original habitat of the western honeybee (Apis mellifera), as it offers nesting sites in the form of tree cavities. Researchers.....»»
Researchers reveal acoustic topological corner anomaly
Topological acoustics provides a new approach for manipulating acoustic waves using the novel wave transport phenomenon. In less than a decade, it has provided a series of promising new ideas for the directional control of acoustic field......»»
Time-varying orbital angular momentum generated by a metasurface
The orbital angular momentum (OAM) of electromagnetic waves—a kind of "structured light"—is associated with a helical or twisted wavefront......»»

"Big sponge": new CO2 tech taps oceans to tackle global warming
Floating in the port of Los Angeles, a strange-looking barge covered with pipes and tanks contains a concept that scientists hope to make waves: a new way to use the ocean as a vast carbon dioxide sponge to tackle global warming......»»
Air pollution is not just a human problem, it"s also changing the guts of British bumble bees
Recent research from the University of Leicester, UK, has identified that air pollution affects the intricate web of microbes that are all around us. Populations of bees are also declining worldwide, so the Leicester team is investigating whether the.....»»
Optically controlled metasurfaces for dynamic dual-mode modulation
Dynamic control of terahertz (THz) waves at will with an ultra-compact device is important for THz technologies in biomedical imaging, telecommunications, detection, and beyond. However, tunable THz devices made of conventional materials are usually.....»»
Waymo vehicles pull over in California due to fog
Google self-driving technology unit Waymo said that some of its vehicles in San Francisco encountered dense fog and briefly pulled over to the side of the road......»»
Does Tesla intend to derail SiC development?
Tesla's disclosure of intention to reduce use of SiC in its electric vehicles (EV) by 75% has sent shock waves across the supply chain, with many companies assessing all possible scenarios and solutions. But there has also been skepticism about wheth.....»»
Researchers investigate involuntary THC exposure in homes
University of Toronto researchers are investigating exposure to second-hand—and even third-hand—marijuana smoke in homes, including the THC that can collect on floors and surfaces......»»
Future Apple Watch band could detect the smallest finger movements and gestures
Apple is investigating how the addition of electrodes to Apple Watch bands could detect the muscle movement and minute electrical activity when a user makes just about any finger gesture.Apple Watch already knows when you're just lazing around and sh.....»»
Apple"s dominance means it needs stricter controls, says Germany"s antitrust regulator
Regulators in Germany have declared that Apple's size and importance means it qualifies for the country's extended anti-competition law, and needs more scrutiny for potential anti-trust violations.Germany is already investigating Apple over the alleg.....»»
Range-boosting battery technology ready for mass EV production
Lighter, more energy dense silicon-based battery anodes could help boost the range of EVs considerably......»»
Researchers discover a way to observe chromatin interaction changes in cancer-associated genetic mutations
Studying the microbiology of any entity, be it a molecule or a dolphin, ideally means putting a spotlight as close to the source material as possible. That can be especially challenging when you're investigating the Rube Goldberg environment of a cel.....»»
Multi-foci metalens for spectra and polarization ellipticity recognition and reconstruction
As fundamental properties of light, spectra and polarization carry vital information concerning the propagation of light waves. For example, spectral imaging can reflect the material composition of objects, while polarized imaging contains informatio.....»»
Can AI be used to predict ocean waves?
The ability to model and predict the size of ocean waves is important for the fishing industry from both logistic and economic perspectives. Essentially, the bigger the waves, the more expensive the fish. Existing ocean wave models use numerical meth.....»»
