Investigating the impact of ultralight dark matter on gravitational wave signals
A recent study in Physical Review Letters explores the effects of ultralight dark matter in extreme-mass-ratio inspirals (EMRIs), which could be detected by future space-based gravitational wave detectors like LISA (Laser Interferometer Space Antenna.....»»
Ocean eddy currents funnel extreme heat and cold to the life-filled depths
On land, we're familiar with heat waves and cold snaps. But the deep sea also experiences prolonged periods of hot and cold......»»
Controlling sound waves with Klein tunneling improves acoustic signal filtration
In the context of sensory modalities, eyes work like tiny antennae, picking up light, electromagnetic waves traveling at blistering speeds. When humans look at the world, their eyes catch these waves and convert them into signals the brain reads as c.....»»
First results from the Axion Dark-Matter Birefringent Cavity experiment establish a new technique for axion search
Researchers at MIT recently published the first results of an experiment aimed at searching for axion dark matter by probing the axion-induced birefringence of electromagnetic waves. While these findings, published in Physical Review Letters, did not.....»»
Second exoplanet detected orbiting an early G-type star
Astronomers report the detection of a second exoplanet orbiting a G-type star known as TIC 393818343, located some 300 light years away. The newfound alien world is about three times less massive than Jupiter. The finding was detailed in a research p.....»»
NASA’s Europa Clipper Spacecraft Aims for Jupiter’s Most Intriguing Moon
For the first time, we are sending a spacecraft to explore an alien ocean world—a moon that might host life today.....»»
Global temperature analysis reveals deep ocean marine heat waves are underreported
While marine heat waves (MHWs) have been studied at the sea surface for more than a decade, new research published today in Nature has found 80% of MHWs below 100 meters are independent of surface events, highlighting a previously overlooked aspect o.....»»
Study suggests dolphins could be exposed to potentially harmful microplastics through inhalation
U.S. researchers have detected microplastic particles in air exhaled by wild bottlenose dolphins, suggesting that inhalation may be a relevant route of exposure to these potentially harmful contaminants. Miranda Dziobak of the College of Charleston i.....»»
Astronomer detects eclipses in a candidate cataclysmic variable system
Russian astronomer Valerij Kozhevnikov has performed photometric observations of a candidate cataclysmic variable known as LAMOST J035913.61+405035.0. He detected 14 eclipses of this system. The finding was reported in a paper published October 9 on.....»»
Dutch students warn space mission of noisy white dwarfs
The background noise of gravitational waves from orbiting white dwarf stars will be stronger than the noise from binary black holes. This is what two Dutch master's students and their supervisor predict in two papers in anticipation of the LISA space.....»»
Spin-wave reservoir chips can enhance edge computing
Reservoir computing (RC) has a few benefits over other artificial neural networks, including the reservoir that gives this technique its name. The reservoir functions mainly to nonlinearly transform input data more quickly and efficiently. Spin waves.....»»
Roku makes monitoring security cameras a little easier
Roku is updating its software for better notifications with its smart-home cameras, and it'll cycle thought them as motion is detected......»»
Astronomers detect very-high-energy gamma-ray emission surrounding distant pulsar
Using the Large High-Altitude Air Shower Observatory (LHAASO), an international team of astronomers have detected very-high-energy (VHE) gamma-rays around the pulsar PSR J0248+6021, which may be the pulsar's halo or a pulsar wind nebula. The finding.....»»
Global warming is happening, but not statistically "surging," new study finds
Given the number of record-setting heat waves around the world in recent years, an international team of researchers, including a Lancaster University statistician, investigated if the rate of global warming has increased significantly, or "surged,".....»»
LIGO team enhances gravitational wave detection with squeezed light
A team of researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO), in the U.S., has developed what they describe as a squeezed light system to improve detection sensitivity......»»
Saturday Citations: All that sparkles is plastic; woke tree diversity; the gravitational basin in which we reside
This week, astronomers considered whether dark energy varies over cosmic timescales. Via neutron analysis, physicists revealed that some Early Iron Age swords were altered recently by swindlers in order to be more historically exciting. And a profess.....»»
Researchers uncover role of plasma waves in mysterious heating of sun"s corona
There is a profound mystery in our sun. While the sun's surface temperature measures around 10,000 degrees Fahrenheit, its outer atmosphere, known as the solar corona, measures more like 2 million degrees Fahrenheit, about 200 times hotter......»»
First greenhouse gas plumes detected with NASA-designed instrument
The imaging spectrometer aboard the Carbon Mapper Coalition's Tanager-1 satellite has identified methane and carbon dioxide plumes in the United States and internationally......»»
Asteroid mining: A potential trillion-dollar industry
Earth's newest celestial neighbor has finally arrived. Astronomers using a powerful telescope in Sutherland, South Africa, first detected the 33-foot-long asteroid in August, reporting their discovery in Research Notes of the American Astronomical So.....»»
What yields per acre reveal about the impact of extreme weather
