Scientists from the Skolkovo Institute of Science and Technology (Skoltech), the Institute of Bioorganic Chemistry (IBCh RAS) and Lomonosov Moscow State University (MSU) undertook a detailed study on green-to-red photoconversion (light-induced conversion) of the Green Fluorescent Protein (GFP). Their research was published in Frontiers of Molecular Biosciences.
Researchers at the Hybrid Photonics Laboratories in Skoltech and Southampton (UK), in collaboration with Lancaster University (UK), have demonstrated a new optical method to synthesize artificial solid-state crystal structures for cavity-polaritons using only laser light. The results could lead to the realization of field-programmable polariton circuitry and new strategies to create guided light and robust confinement of coherent light sources. The results were recently published in the journal Nature Communications.
Research findings from Aarhus University and the Central Denmark Region's Child and Adolescent Psychiatric Centre show that quality of life is poorer for preschool children with ADHD compared to children from the control population. But the children's quality of life can be significantly improved using treatment without medication.
Researchers of Karlsruhe Institute of Technology (KIT) and Heidelberg University have developed a photoresist for two-photon microprinting. It has now been used for the first time to produce three-dimensional polymer microstructures with cavities in the nano range. In Advanced Materials, the scientists involved in the joint Cluster of Excellence 3D Matter Made to Order report how porosity can be controlled during printing and how this affects light scattering properties of the microstructures.

Researchers at the Microsoft Quantum Materials Lab and the University of Copenhagen, working closely together, have succeeded in realizing an important and promising material for use in a future quantum computer. For this end, the researchers have to create materials that hold the delicate quantum information and protect it from decoherence.
Using the X-ray laser European XFEL, a research team has investigated how water heats up under extreme conditions. In the process, the scientists were able to observe water that remained liquid even at temperatures of more than 170 degrees Celsius. The investigation revealed an anomalous dynamic behaviour of water under these conditions. The results of the study, which are published in the Proceedings of the National Academy of Sciences (PNAS), are of fundamental importance for the planning and analysis of investigations of sensitive samples using X-ray lasers.
Researchers from the Moscow Institute of Physics and Technology and King's College London cleared the obstacle that had prevented the creation of electrically driven nanolasers for integrated circuits. The approach, reported in a recent paper in Nanophotonics, enables coherent light source design on the scale not only hundreds of times smaller than the thickness of a human hair but even smaller than the wavelength of light emitted by the laser. This lays the foundation for ultrafast optical data transfer in the manycore microprocessors expected to emerge in the near future.
3D printing has driven innovations in fields ranging from art to aerospace to medicine. However, the high-energy ultraviolet (UV) light used in most 3D printers to cure liquid resins into solid objects limits the technique's applications. Visible-light curing, which would be more appropriate for some uses, such as tissue engineering and soft robotics, is slow. Now, researchers reporting in ACS Central Science have developed photopolymer resins that boost the speed of visible-light curing.
Optical signals produced by laser sources are extensively used in fiber-optic communications, which work by pulsing information packaged as light through cables, even at great distances, from a transmitter to a receiver. Through this technology it is possible to transmit telephone conversations, internet messages and cable television images. The great advantage of this technology over electrical signal transmission is its bandwidth -- namely, the amount of information that can be broadcast.
Before autonomous vehicles participate in road traffic, they must demonstrate conclusively that they do not pose a danger to others. New software developed at the Technical University of Munich (TUM) prevents accidents by predicting different variants of a traffic situation every millisecond.
UTICA, NY -- Researchers from the? Masonic Medical Research Institute (MMRI), the Precision Cardiology Lab (PCL) of the Broad Institute at MIT and Harvard, Bayer USA, Massachusetts General Hospital, and University of Pennsylvania collaborated to uncover some pressing questions about the biology of the heart. While understanding the mechanisms causal to human heart disease remain active areas of research for many scientists, important knowledge gaps about its composition and function remain unknown.
ITHACA, N.Y. - When stars like our sun die, all that remains is an exposed core - a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its star, according to Cornell University researchers.
In a study published in the Astrophysical Journal Letters, they show how NASA's upcoming James Webb Space Telescope could find signatures of life on Earth-like planets orbiting white dwarfs.
The concentration of mercury in fish in Alaska's Yukon River may exceed EPA mercury criterion by 2050 if greenhouse gas emissions that cause global warming are not constrained, according to new scientific research led by the National Snow and Ice Data Center's (NSIDC) Kevin Schaefer. This first of its kind research estimates potential releases of mercury from thawing permafrost in high and low emissions scenarios.
HOUSTON - (Sept. 16, 2020) - A simpler and more efficient way to predict performance will lead to better batteries, according to Rice University engineers.
That their method is 100,000 times faster than current modeling techniques is a nice bonus.
The analytical model developed by materials scientist Ming Tang and graduate student Fan Wang of Rice University's Brown School of Engineering doesn't require complex numerical simulation to guide the selection and design of battery components and how they interact.
A team of researchers from North Carolina State University has demonstrated a way to use low-energy, visible light to produce polymer gel objects from pure monomer solutions. The work not only poses a potential solution to current challenges in producing these materials, it also sheds further light on the ways in which low energy photons can combine to produce high energy excited states.
