Apple is buying a treasure in Pixelmator, and we hope it won"t get destroyed
If Apple's surprise acquisition of Mac developer Pixelmator passes the regulators, the future of its beloved apps may be bright — or there could be dark skies ahead.Dark Sky (left) was shut down, Apple Music Classical (right) came from an acquisiti.....»»
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,.....»»
Astronomers investigate the properties of open cluster NGC 2506
Astronomers from the University of Wisconsin–Madison and Harvard–Smithsonian Center for Astrophysics (CfA) have inspected a Galactic open cluster known as NGC 2506 as part of the WIYN Open Cluster Study. Results of the study, published October 14.....»»
Machine-learning analysis tracks the evolution of 16th-century European astronomical thought
A team of computer scientists, astronomers and historians in Berlin has used machine-learning applications to learn more about the evolutionary history of European astronomical thought in the 15th and 16th centuries. In their study published in the j.....»»
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.....»»
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.....»»
Solar-powered animal cells: Combining chloroplasts from algae with hamster cells
Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining chloroplasts (chlorophyll containing structures in.....»»
Study models dinoflagellate light in breaking waves
A new study led by Scripps Institution of Oceanography demonstrates, for the first time, how scientists can use computer simulations to quantify the light emitted by dinoflagellates when they flash in breaking waves and create stunning displays of bi.....»»
New extended and faint tidal tail discovered
By analyzing the data from the Dark Energy Camera Legacy Survey (DECaLS), astronomers have discovered a new tidal tail likely associated with the galaxy NGC 3785. The newly detected tidal tail is extremely extended and faint. The finding was reported.....»»
Innovative model offers new way for astronomers to analyze powerful space explosions
Astrophysical explosions are, to give a few examples, driven by the collapse of the iron core of a massive star (known as a core-collapse supernova), the consumption of spaghettified stellar remains by a massive black hole (known as a tidal disruptio.....»»
Astronomers discover one of the fastest-spinning stars in the universe
A new study by DTU Space researchers has revealed a neutron star that rotates around its axis at an extremely high speed. It spins 716 times per second, making it one of the fastest-spinning objects ever observed......»»
