Researchers investigate role of water molecules in formation of condensates in cells
In order to fulfill their function, biological cells need to be divided into separate reaction compartments. This is sometimes done with membranes, and sometimes without them: the spontaneous segregation of certain types of biomolecules leads to the.....»»
Researchers propose 3D printing of high-performance elastomers through vat photopolymerization
Acrylate-based ultraviolet (UV)-curable resins are currently used as raw materials to obtain desired performance by adjusting the types and ratios of oligomer and reactive monomers in the resin system. However, due to low degree of free-radical polym.....»»
Researchers fabricate chip-based optical resonators with record low UV losses
Researchers have created chip-based photonic resonators that operate in the ultraviolet (UV) and visible regions of the spectrum and exhibit a record low UV light loss. The new resonators lay the groundwork for increasing the size, complexity and fid.....»»

Successful optical biosensing using dual optical combs: High sensitivity and rapid detection of biomolecules
Bio-sensors are biomolecular sensors that leverage or mimic the sophisticated molecular recognition capabilities of living organisms. They find widespread applications in fields such as health care, food, and the environment......»»
Copper-infused nanocrystals boost infrared light conversion
Sunlight is an inexhaustible source of energy, and utilizing sunlight to generate electricity is one of the cornerstones of renewable energy. More than 40% of the sunlight that falls on Earth is in the infrared, visible and ultraviolet spectra; howev.....»»
Researchers create optical device that can kill pathogens on surfaces while remaining safe for humans
While it has long been known that ultraviolet (UV) light can help kill disease-causing pathogens, the COVID-19 pandemic has put a spotlight on how these technologies can rid environments of germs. However, the excimer lamps and LEDs that can directly.....»»
Scientists ‘hack’ Solar Orbiter’s camera to better look at the sun
The instrument team for the Solar Orbiter's ultraviolet camera have found a new way to make use of the instrument to help it peer into the sun's atmosphere......»»
Camera "hack" lets Solar Orbiter peer deeper into sun"s atmosphere
Scientists have used Solar Orbiter's EUI camera in a new mode of operation to record part of the sun's atmosphere at extreme ultraviolet wavelengths that has been almost impossible to image until now. This new mode of operation was made possible with.....»»
Micro-optical technology based on metamaterials takes center stage
Metasurfaces are artificial materials adept at manipulating perception. With metasurfaces allowing lenses to be reduced to one 10,000th the size of conventional lenses, they are generating considerable interest as optical components allowing miniatur.....»»
New X-ray detectors to provide unprecedented vision of the invisible universe
Very detailed information is now available from ultraviolet, optical, and submillimeter observations of the stellar, dust, and cold gas content of galaxies, and yet there is a dearth of understanding about the mechanisms that formed these galaxies. T.....»»
New research finds veterinary school transmits culture, not just data, to students
In a pair of new studies, researchers from North Carolina State University have found that as veterinary students progress through their coursework, their beliefs about dog breeds' pain sensitivity and trustworthiness change, becoming more in line wi.....»»
Study finds new type of cell related to organ movement for self-pollination in plants
A study led by Dr. Yin-Zheng Wang (Institute of Botany, the Chinese Academy of Sciences) has found that the stigma of Chirita pumila has movement and proved that the motion is associated with water sensitivity. Further, through anatomical studies, it.....»»
Dog brains are tuned to dog-directed speech spoken by women
Dogs show greater brain sensitivity to the speech directed at them than to adult-directed speech, especially if spoken by women, according to a new study in Communications Biology......»»
Study explains how part of the nucleolus evolved
Inside all living cells, loosely formed assemblies known as biomolecular condensates perform many critical functions. However, it is not well understood how proteins and other biomolecules come together to form these assemblies within cells......»»
Biologists find what colors a butterfly"s world
As butterflies flit among flowers, they don't all view blossoms the same way. In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. University of California,.....»»
iPhone 16 Pro cameras may have double the low-light sensitivity [Video]
While all four iPhone 15 models are expected to get the 48MP stacked sensor tech used in the iPhone 14 Pro and Pro Max, next year’s iPhone 16 Pro cameras may again pull ahead of the base and Plus models. A new supply chain report today isn’t s.....»»
