Astronomers detect ancient lonely quasars with murky origins
A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of energy, making quasars some of the brightest object.....»»
Observations explore the nature of transitional millisecond pulsar PSR J1023+0038
Using the Gran Telescopio Canarias (GTC), astronomers from Italy and Spain have carried out high-temporal-resolution optical spectroscopic observations of a transitional millisecond pulsar designated PSR J1023+0038. Results of the observational campa.....»»
Geologists discover mysterious subduction zone beneath Pacific, reshaping understanding of Earth"s interior
University of Maryland scientists uncovered evidence of an ancient seafloor that sank deep into Earth during the age of dinosaurs, challenging existing theories about Earth's interior structure. Located in the East Pacific Rise (a tectonic plate boun.....»»
Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb
Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimp.....»»
Apple patent describes using AirPods to detect heart disease, likely next year
9to5Mac recently discovered evidence in iOS 18 that Apple is testing using future AirPods models to measure heartbeat, with our sources indicating that the feature will be implemented in both AirPods Pro 3 and the next generation of Powerbeats Pro......»»
Dynasty Warriors: Origins makes bold changes, and they’re already paying off
We just got our first taste of Dynasty Warriors: Origins, which feels just as thrilling as the franchise ever has, even with a few new changes......»»
Hubble finds that a black hole beam promotes stellar eruptions
In a surprise finding, astronomers using the NASA/ESA Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called.....»»
Simultaneous detection of uranium isotopes and fluorine advances nuclear nonproliferation monitoring
Combining two techniques, analytical chemists at the Department of Energy's Oak Ridge National Laboratory have become the first to detect fluorine and different isotopes of uranium in a single particle at the same time. Because fluorine is essential.....»»
How old is beer?
Humans are no strangers to kicking back with a cool pint of beer. The Ancient Egyptians, for example, had a hankering for beer that was a little bit tart, almost like a modern-day gose, a lemony beer from Germany. Homer, the Ancient Greek poet, spoke.....»»
‘That’s weird’: This galaxy could help astronomers understand the earliest stars
Astronomers using the James Webb Space Telescope have spotted a weird galaxy that originated just a billion years after the Big Bang......»»
Frozen in time: Rock fossils hint at Mars"s ancient climate
Long ago, flowing wind and water shaped Mars's malleable sand and sediment into dunes, ripples and other landscape patterns, called bedforms. Over billions of years, some of these landforms hardened into rock—scientists then call them paleo-bedform.....»»
Study shows that ancient reef-building stromatoporoids dodged extinction—at least temporarily
Will modern coral reefs go extinct? The answer is uncertain, but some of their ancient counterparts managed to dodge a bullet—for a while, at least......»»
Medicinal tree successfully grown from 1,000-year-old seed found in cave
An international team of botanists, agriculturists and historians has successfully grown a mature tree from an ancient seed found in a cave in Israel. In their paper, published in the journal Communications Biology, the group describes where the seed.....»»
New evolutionary model revises the origins of biodiversity
An international team of scientists has made a discovery that could reshape our understanding of how global biodiversity evolved. By reconstructing the evolution of species over the past 45 million years, researchers found that the geographic origins.....»»
Afar mantle plume study offers new insight into deep Earth processes
Sophisticated analysis of tiny bubbles of ancient gas trapped in volcanic rocks, combined with new geophysical modeling, has cast new light on long-held assumptions about the deep Earth......»»
Ancient DNA helps uncover the Iberian lynx"s potential secret weapon against extinction
Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a "genetic database" to fall back on to ad.....»»
1,000-year-old textiles reveal cultural resilience in the ancient Andes
Archaeologists have analyzed textiles from the ancient city of Huacas de Moche, Peru, showing how the population's cultural traditions survived in the face of external influence......»»
Astronomers catch a glimpse of a uniquely inflated and asymmetric exoplanet
An international group of researchers including University of Arizona astronomers, using NASA's James Webb Space Telescope, has observed the atmosphere of a hot and uniquely inflated exoplanet. The exoplanet, which is the size of Jupiter but only a t.....»»
Enigmatic archaeological site in Madagascar may have been built by people with Zoroastrian origins, research suggests
At the turn of the first millennium AD, an unknown group of people lived in the inland Isalo massif of southern Madagascar. Here, they built vast terraces and carved large stone chambers and small hollow rock niches. The architecture is unlike anythi.....»»
Observations confirm that early-universe quasar neighborhoods are densely populated with companion galaxies
Quasars are the most luminous objects in the universe and are powered by material accreting onto supermassive black holes at the centers of galaxies......»»
High-resolution images of the sun show how flares impact the solar atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from ex.....»»
