Trapping light with disorder
Like a pinball game in the hands of a good player, a collection of obstacles randomly positioned can be sufficient to trap light without the need for an optical cavity. By adding amplification, at no cost, a mirrorless laser—often dubbed "random la.....»»
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,.....»»
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.....»»
Scientist on personal mission to improve global water safety makes groundbreaking discovery
A study published in Environmental Science & Technology Letters and led by the University of Bristol sheds new light on how arsenic can be made less dangerous to humans has the potential to dramatically improve water and food safety, especially in th.....»»
Tracking a disappearing mantle plume in ancient Samoa: Researchers shed light on a 30-million-year gap
When plumes of magma well up through Earth's lithosphere, they create volcanoes, islands, seamounts, and other features on the surface. Telltale hot spot tracks form as tectonic plates move over these plumes, marking plume locations and the movement.....»»
Seeing a black hole"s jet in a new light: A look at high-energy particles being blasted across space
Research led by the University of Michigan has pored over more than two decades' worth of data from NASA's Chandra X-Ray Observatory to show there's new knotty science to discover around black holes......»»
Largest-Ever Pair of Black Hole Jets Stretches 23 Million Light-Years
Supermassive black holes can expel jets of material so vast and powerful that they may shape the large-scale structure of the cosmos.....»»

HomeKit Weekly: THIRDREALITY Smart Color Night Light is the perfect HomeKit accessory for a child’s room or hallway
The ideal HomeKit accessories run themselves. Turning off and on lights from an app is a nice feature, but it’s a similar level of effort to using a light switch. The real magic is when you can “set it and forget it.” The is the perfect exampl.....»»
Study: DNA corroborates “Well-man” tale from Norse saga
The "Well-man" likely had blue eyes, blond or light-brown hair, and hailed from southern Norway. A 12th-century Norse saga tells of an invading army from the south razing a castl.....»»
Optical technique that uses orbital angular momentum could transform medical diagnostics
An Aston University researcher has developed a new technique using light that could revolutionize non-invasive medical diagnostics and optical communication. The research showcases how a type of light called the orbital angular momentum (OAM) can be.....»»
New deep ultraviolet micro-LED array advances maskless photolithography
A team led by Prof. Sun Haiding from the University of Science and Technology of China (USTC) developed a vertically integrated micro-scale light-emitting diode (micro-LED) array which was then applied in deep ultraviolet (DUV) maskless photolithogra.....»»
Novel light source enables better temporal resolution of UV-induced molecular dynamics
The Attosecond Science group at the Center for Free-Electron Laser Science has developed a novel light source capable of producing extremely short pulses for the investigation of UV-induced molecular dynamics with unprecedented temporal resolution. S.....»»
Search results for dark photon leptonic decays manage to exclude new regions
Dark photons are hypothetical particles that resemble light particles (i.e., photons), but interact weakly with normal matter, which would make them impossible or very difficult to detect using conventional experimental methods. These particles are d.....»»
On the way to light-controlled medicine: Researchers elucidate the structure of specific photoreceptors
Researchers in biology and medicine have long dreamed of controlling the activities of cells without, for example, having to use chemicals. After all, in a structure as complex as an entire organism, unwanted side-effects can often arise......»»
