The Kilonova-Chasing Gravitational-Wave Optical Transient Observer is about to be watching the whole sky
Lately, there has been a flood of interest in gravitational waves. After the first official detection at LIGO / Virgo in 2015, data has been coming in showing how common these once theoretical phenomena actually are. Usually they are caused by unimag.....»»
High-refractive-index-modulation nanocomposites for augmented reality displays
Holographic optical elements (HOEs) are essential in augmented reality (AR) displays, providing benefits such as design flexibility and improved optical efficiency. However, current materials' limited refractive index modulation hampers performance,.....»»

Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»
Five lessons from ancient civilizations for keeping homes cool in hot, dry climates
Modern buildings tend to take electricity and air conditioning for granted. They often have glass facades and windows that can't be opened. And when the power goes out for days in the middle of a heat wave, as the Houston area experienced in July 202.....»»
Webb discovers six new "rogue worlds" that provide clues to star formation
Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out......»»
85% of the matter in the universe is missing: But scientists are getting closer to finding it
Most of the matter in the universe is missing. Scientists believe around 85% of the matter in the cosmos is made of invisible dark matter, which has only been detected indirectly by its gravitational effects on its surroundings......»»
Spin-controlled generation of a complete polarization set with randomly interleaved plasmonic metasurfaces
Optical metasurfaces are finely crafted two-dimensional artificial nanostructures composed of meticulously designed arrays of ultrathin artificial atoms. These surfaces possess capabilities beyond natural materials, enabling multifunctional control o.....»»
Advances in optical micronanofiber-enabled tactile sensors and soft actuators
A perfect combination of fiber optics and micro/nanotechnology, optical micro/nanofiber (MNF) is a new type of micro/nano-waveguide structure developed in recent years......»»
Air conditioning poses a climate conundrum
This week, much of the US is suffering from yet another heat wave. So far this year, 15 countries have set records for high heat. Last July, the average global temperature, factoring in heat waves in multiple regions around the world, was likely the.....»»
Like people, vultures get set in their ways and have fewer friends as they age
If you'd rather be watching TV on your couch than dancing at the club, you might have something in common with aging griffon vultures. New research shows that young griffon vultures move frequently between sleeping sites in different locations and in.....»»
New Sisyphus cooling technique could enhance precision of atomic clocks
Researchers in the Neutral Atom Optical Clocks Group at the National Institute of Standards and Technology (NIST), University of Colorado and Pennsylvania State University recently devised a new sub-recoil Sisyphus cooling technique that could help t.....»»
During a heat wave, "stay indoors" can bring hazards, too
With Chicago and much of the Midwest facing what may be the hottest days of the summer this week, many are cranking up the air conditioning and heeding the advice of officials to stay inside......»»
Kelvin wave research may lead to more accurate forecasting of active hurricane periods
More accurately predicting periods of increased hurricane activity weeks in advance may become possible due to new research published this month published in the journal Monthly Weather Review......»»
Researchers propose inexpensive 2.2-kilometer telescope that could make exoplanet movies
Can a kilometer-scale telescope help conduct more efficient science, and specifically for the field of optical interferometry? This is what a study recently posted to the preprint server arXiv hopes to address......»»
