Massive merger: Study reveals evidence for origin of supermassive black hole at galaxy"s center
The origins of aptly named supermassive black holes—which can weigh in at more than a million times the mass of the sun and reside in the center of most galaxies—remain one of the great mysteries of the cosmos......»»
Plasmonic modulators could enable high-capacity space communication
Researchers have achieved data rates as high as 424Gbit/s across a 53-km turbulent free-space optical link using plasmonic modulators—devices that use special light waves called surface plasmon polaritons to control and change optical signals. The.....»»
AI helps distinguish dark matter from cosmic noise
Dark matter is the invisible force holding the universe together—or so we think. It makes up about 85% of all matter and around 27% of the universe's contents, but since we can't see it directly, we have to study its gravitational effects on galaxi.....»»
Gravitational waves unveil previously unseen properties of neutron stars
A better understanding of the inner workings of neutron stars will lead to a greater knowledge of the dynamics that underpin the workings of the universe and also could help drive future technology, said the University of Illinois Urbana-Champaign ph.....»»
Eclipses create atmospheric gravity waves, student teams confirm
Student teams from three U.S. universities became the first to measure what scientists have long predicted: eclipses can generate ripples in Earth's atmosphere called atmospheric gravity waves. The waves' telltale signature emerged in data captured d.....»»
Researchers prove 120-million-year-old volcanism on moon
Extensive geologic evidence of ancient volcanic activity can be found on the moon, but how long this volcanism persisted has been unclear. However, Prof. Li Qiuli's Lab at the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IG.....»»

Heat waves and droughts cause billions of dollars in global economic losses, research finds
Severe weather costs the global economy billions of dollars a year, highlighting the costs of climate change and the value of mitigating extreme weather, according to a new analysis of weather and economic data......»»
Nanostructures enable on-chip lightwave-electronic frequency mixer
Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard clearly on the other end. The process enabling this shif.....»»
Scientists demonstrate octave-spanning soliton frequency combs on thin-film lithium niobate
The invention of optical frequency combs revolutionized frequency metrology and time-keeping. Miniaturization of such combs onto photonic chips, primarily leveraging the microresonator Kerr soliton frequency comb, expands on these functionalities by.....»»
How gravitational waves could help detect Star Trek-style warp drive spaceships
How much do we really know about what else is out there in the universe?.....»»
Study finds program boosts cognitive engagement of students with language and attention difficulties
A new study has found high school students with disabilities impacting language and information processing were able to better comprehend content when teachers adopted evidence-based strategies to increase the accessibility of classroom teaching......»»
Scientists demonstrate giant THz Kerr effect via stimulated phonon polaritons
Terahertz (THz) waves and THz technologies have gradually opened a new style for communications, cloud-based storage/computing, information contest, and medical tools. With the advancement of THz technologies, studies on THz nonlinear optics have eme.....»»
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.....»»
DEI policies work best when they are designed to include everyone and are backed by evidence, says researcher
As the U.S. becomes increasingly polarized, diversity, equity and inclusion—also known as DEI—efforts have been touted as a way to bridge social divides and promote a sense of belonging for everyone, especially for those who have been traditional.....»»
Seismic echoes reveal a mysterious "donut" inside Earth"s core
About 2,890 kilometers beneath our feet lies a gigantic ball of liquid metal: our planet's core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound to "see" the shape and structure of the core......»»
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......»»
Students Find New Evidence of the Impossibility of Complete Disorder
A new mathematic proof marks the first progress in decades on a problem about how order emerges......»»
