A single atom can change the directional profile of the light emitted in scanning tunneling microscopes
Researchers from Madrid explain a phenomenon that allows the direction of light emission to be controlled at the atomic scale. The paper provides a detailed explanation of how the profile of the light collected in a scanning tunneling microscope (STM.....»»
Scientists discover all-optical nuclear magnetic resonance analog with quantum fluids of light
Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir an exciton-polariton condensate, which emits a linearly polarized light with a polarization a.....»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
Multi-layered site in Tajikistan"s Zeravshan Valley uncovered, offering new insights into human expansion
In an important discovery, archaeologists from the Hebrew University of Jerusalem and the National Academy of Sciences of Tajikistan have uncovered a multi-layered archaeological site in the Zeravshan Valley, central Tajikistan, shedding rare light o.....»»
Report reveals challenges facing transnational families
A new report from the University of Reading brings to light the unique and often overlooked challenges faced by families living across national borders......»»
Green shoots spring from ashes in Brazil"s fire-resistant savanna
The huge wildfires that ripped through Brazil recently did not spare its vast tropical savanna, but green shoots are already emerging from the ashes there, proof of the vast grasslands' rare gift for fire resistance......»»
New digital light manufacturing approach resolves common problems associated with 3D printing
A team of materials scientists, medical researchers and engineers affiliated with a large number of institutions across Australia has developed a new way to conduct digital light manufacturing that overcomes problems with current methods. In their pa.....»»
There Are Three Types of Twilight
At dusk and dawn, the sky dances with three phases of in-between light.....»»
Cloud-inspired method of guiding light: Waveguiding mechanism could provide new ways to look inside the human body
Scientists have taken inspiration from the way sunlight passes through clouds to discover an entirely new way of controlling and guiding light......»»
Chiral molecular self-assemblies that absorb light boost singlet fission process, research demonstrates
In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process wher.....»»
Astronomers predict the orbits of potentially hazardous comets from meteor showers
Comets have long been seen as omens and portents, and it's easy to understand why. They first appear as faint smudges of light in the sky, sometimes fading soon after and sometimes becoming brighter than the planets, with a long, glowing tail. They h.....»»
A new paradigm for control of quantum emitters—modulating and encoding quantum photonic info on a single light stream
A U.S. Naval Research Laboratory (NRL) multi-disciplinary team developed a new paradigm for the control of quantum emitters, providing a new method for modulating and encoding quantum photonic information on a single photon light stream......»»
New method successfully recycles carbon fiber composite into reusable materials
USC researchers have developed a new process to upcycle the composite materials appearing in automobile panels and light rail vehicles, addressing a current environmental challenge in the transportation and energy sectors. The study recently appeared.....»»

Destructive weed, found in New York state, resists common herbicides
The invasive pigweed Palmer amaranth, first found in New York soybean fields in 2019, has been dubbed the "spotted lanternfly of weeds" for its ability to spread quickly and wreak havoc on crops. Now a new study sheds light on how formidable an oppon.....»»
A novel state of thorium opens the possibility for a nuclear clock
Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so in principle it should be less susceptible to outside noise (in the form of light). A nucleus, for high-atomic number atoms,.....»»
Scientists develop starch nanocomposite films that pave the way for green electronics
Queen Mary University of London researchers have developed new nanocomposite films using starch instead of petroleum-based materials, marking a significant advancement in the field of sustainable electronics......»»
Accelerating 3D nanofabrication using a sensitive cationic photoresist
Two-photon laser direct writing lithography or TPL is a cutting-edge technique used for creating nanoscale structures. It works by leveraging specific materials known as photoresists, which change their chemical properties when exposed to light. Thes.....»»
NASA to launch solar coronagraph to Space Station
NASA's Coronal Diagnostic Experiment (CODEX) is ready to launch to the International Space Station to reveal new details about the solar wind including its origin and its evolution......»»
Optical amplifier and record-sensitive receiver pave the way for faster space communication
In space exploration, long-distance optical links can now be used to transmit images, films and data from space probes to Earth using light. But in order for the signals to reach all the way and not be disturbed along the way, hypersensitive receiver.....»»
