Q&A: Researcher discusses how gravitational waves hint at dark matter and Big Bang mysteries
Gravitational waves, ripples in space-time predicted by Einstein almost a century ago, were detected for the first time in 2015. A new study led by Yanou Cui, an associate professor of physics and astronomy at the University of California, Riverside,.....»»
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.....»»

HomeKit Weekly: Why aren’t we seeing new HomeKit Secure Video cameras?
HomeKit has become a powerful platform, with Apple consistently enhancing its features while staying true to its privacy-first approach. They’ve even contributed to the Matter standard, expanding what the Home app can do. But there’s a big proble.....»»
Why are black holes stable against their own gravity?
Neutron stars are timelike matter with a maximum mass of about 2.34 solar masses in quantum chromodynamics (the strong color force). Black holes are spacelike matter that have no maximum mass, but a minimum mass of 2.35 solar masses. Indeed, black ho.....»»
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.....»»
Unlocking oceanic mysteries: Satellites shed light on aerosol layer height
Aerosol layer height (ALH) is a key parameter for assessing aerosol impacts on weather, climate, and atmospheric correction. Accurate ALH retrieval improves the understanding of aerosol-cloud interactions and aids in surface air quality monitoring......»»
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.....»»
The Moon had volcanic activity much more recently than we knew
Eruptions seem to have continued long after widespread volcanism had ended. Enlarge / The eruptions that produced the dark mare on the lunar surface ended billions of years ago. (credit: NASA/GSFC/Arizona State University).....»»
Tidal wetlands study offers improved predictions of methane gas emissions
An international study led by UAB researcher Ariane Arias-Ortiz, and published in Global Change Biology, has analyzed methane gas fluxes in more than 100 tidal wetlands and marshes in the U.S......»»

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......»»
Researcher helps develop new technique to explore oceanic microbes
When Southern Methodist University (SMU) researcher Alexander Chase was a young boy, the sheer diversity of plants in Earth's tropical rainforests fascinated him. He found himself wondering what new species were out there, waiting to be unearthed. Th.....»»
Poor people are business owners, too—but myths around poverty and entrepreneurship hold them back, says researcher
Nearly 1 in 5 people in the world lives in poverty. Even in many developed countries such as the U.S., poverty rates exceed 12%. In an age of breathtaking technological progress and dynamic social change, poverty remains stubbornly persistent......»»
New method captures the stochastic dynamics in coherent X-ray imaging at the nanoscale
Coherent X-ray imaging has emerged as a powerful tool for studying both nanoscale structures and dynamics in condensed matter and biological systems. The nanometric resolution together with chemical sensitivity and spectral information render X-ray i.....»»
City light pollution is shrinking spiders" brains, new study finds
