Light pollution is taking the sparkle out of glow-worm mating
The invention of electric light has extended our lives deeper into the night: street lamps help us travel more safely outdoors, while lighting indoors lets us work and play for longer. Entire stadiums are drenched in light so that people can watch sp.....»»
Scientists observe "negative time" in quantum experiments
Scientists have long known that light can sometimes appear to exit a material before entering it—an effect dismissed as an illusion caused by how waves are distorted by matter......»»
Wireless antennas harness light to decode cellular communication signals
Monitoring electrical signals in biological systems helps scientists understand how cells communicate, which can aid in the diagnosis and treatment of conditions like arrhythmia and Alzheimer's......»»
New electron microscopy technique reveals complex spin structures at femtosecond timescales
Plasmons are collective oscillations of electrons in a solid and are important for a wide range of applications, such as sensing, catalysis, and light harvesting. Plasmonic waves that travel along the surface of a metal, called surface plasmon polari.....»»
Advancing light control: New opportunities for metasurfaces in optoelectronics
A global review of advancements in integrating metasurfaces—thin planar arrays of nanostructures—into optoelectronic devices highlights their potential to transform technologies such as light emitting diodes (LEDs), lasers, optical modulators, an.....»»

EPA investigating taconite mine for pollution that threatens wild rice
In a novel attempt to enforce a longstanding Minnesota rule protecting wild rice, the EPA is investigating U.S. Steel's taconite mine, Keetac, for repeatedly releasing a rice-killing pollutant into surface waters......»»
Compact on-chip polarimeter measures light polarization with high accuracy
Reliably measuring the polarization state of light is crucial for various technological applications, ranging from optical communication to biomedical imaging. Yet conventional polarimeters are made of bulky components, which makes them difficult to.....»»
Environmental groups challenge update to California"s low-carbon transportation rules
A coalition of environmental groups challenged California's leading climate regulator on Wednesday, alleging that a recent update to a leading climate program will create additional pollution in the state's San Joaquin Valley......»»
How to solve the Three Eyed Gate puzzle in Indiana Jones and the Great Circle
Even Indy doesn't like light puzzles in Indiana Jones and the Great Circle. The three eyed gate puzzle is mandatory, though, so we will help you solve it......»»
The New Glenn rocket’s seven powerful engines may light up as soon as today
"Maybe, maybe, maybe today, maybe soon. I think it's very soon." In a widely anticipated test, Blue Origin may ignite the seven main engines on its New Glenn rocket as soon as Thu.....»»
Prototype sunscreen uses TiO₂ nanoparticles to cool skin while blocking UV rays
Wearing sunscreen is important to protect your skin from the harmful effects of UV radiation but doesn't cool people off. However, a new formula, described in Nano Letters, protects against both UV light and heat from the sun using radiative cooling......»»
Scientists recreate molecular timers to control nanomachine activation rates
Living organisms monitor time—and react to it—in many different ways, from detecting light and sound in microseconds to responding physiologically in pre-programmed ways, via their daily sleep cycle, monthly menstrual cycle, or to changes in the.....»»
Optical spring enables programmable defect mode in new mechanical crystal
Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these crystals (i.e., intentional.....»»
SpaceX gets green light for seventh Starship test, but when is it?
The FAA has given the nod to SpaceX to conduct its seventh Starship test from its Starbase site in Texas......»»
Distant blazar discovery supports rapid black hole formation in the early universe
Astronomers have discovered an important piece of the puzzle of how supermassive black holes were able to grow so quickly in the early universe: a special kind of active galactic nucleus so distant that its light has taken more than 12.9 billion year.....»»
Antineutrino detection gets a boost with novel plastic scintillator
How do you find and measure nuclear particles, like antineutrinos, that travel near the speed of light?.....»»
Dying Light: The Beast: release date window, trailers, gameplay, and more
The next chapter in the Dying Light universe isn't called Dying Light 3, but Dying Light: The Beast. Try not to get bit as we run through everything we know......»»
Scientists provide insights into photosystem II under low-light conditions
In higher plants and green algae, photosystem II (PSII) usually combines with light harvesting complex II (LHCII) to form the PSII-LHCII supercomplex. Under low-light conditions, the PSII-LHCII supercomplexes are organized laterally into higher-order.....»»
Layer by layer: How simulations help manufacturing of modern displays
Modern materials must be recyclable and sustainable. Consumer electronics is no exception, with organic light-emitting diodes (OLEDs) taking over modern televisions and portable device displays. However, the development of suitable materials—from t.....»»
