What Lit the Lamps That Let Humanity Measure the Universe
Type Ia supernovas are astronomers’ best tools for measuring cosmic distances. In a first, researchers recreated one on a supercomputer to learn how they form......»»
New models of Big Bang show that visible universe and invisible dark matter co-evolved
Physicists have long theorized that our universe may not be limited to what we can see. By observing gravitational forces on other galaxies, they've hypothesized the existence of "dark matter," which would be invisible to conventional forms of observ.....»»
House passes bill saying ByteDance must sell or spin off TikTok or face a ban
The US House of Representatives has passed a combination bill related to sanctions on other countries, such as Russia that includes language that could force the sale or divestiture of TikTok.Legislators have framed the measure in such a way as to do.....»»
Climate impacts set to cut 2050 global GDP by nearly a fifth
Climate change caused by CO2 emissions already in the atmosphere will shrink global GDP in 2050 by about $38 trillion, or almost a fifth, no matter how aggressively humanity cuts carbon pollution, researchers said Wednesday......»»
War never changes: A Fallout fan’s spoiler-laden review of the new TV series
The show preserved the themes, archetypes, chronology, and more for the games. Enlarge / The nukes went off in 2077 in Fallout's universe. The show tells us more about this event than we've learned from the games before. (credit:.....»»

Study reveals how humanity could unite to address global challenges
New research led by the University of Oxford has found that perceptions of globally shared life experiences and globally shared biology can strengthen psychological bonding with humanity at large, which can motivate prosocial action on a global scale.....»»
Scientists develop framework to measure plastic emissions and bolster U.N. efforts to reduce pollution
University of Toronto (U of T) scientists have developed a framework for measuring plastic pollution emissions akin to the global standard for measuring greenhouse gas emissions. The researchers say the approach will boost identification of the bigge.....»»
Future Apple Vision Pro could help the user get life-saving medical advice
Apple is developing technology for wearable devices like Apple Vision Pro that measure and monitor biometric data and location to provide tailored and potentially lifesaving advice.Apple wearables could provide medication reminders and guidance. An A.....»»
Why figuring out how potassium is destroyed in stars is important to understanding the universe
If you want to know where elements come from, look to the stars. Almost every element heavier than helium is formed through nuclear reactions in stars. But which stellar processes are responsible for these elements? Can we find patterns in how much o.....»»
Study uses thermodynamics to describe expansion of the universe
The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American astronomer Edwin Hubble (1889-1953) two years l.....»»
The Paradox That"s Supercharging Climate Change
Humanity needs to burn less fossil fuels. But that means fewer aerosols to help cool the planet—and a potential acceleration of global warming......»»
Saturday Citations: Listening to bird dreams, securing qubits, imagining impossible billiards
It's Saturday, which means that in a universe where the arrow of time moves backward, people have to go to work tomorrow. In such a hypothetical universe, Garfield hates Fridays—tough to imagine. This week, we looked at several hundred breaking sci.....»»
Physicists solve puzzle about ancient galaxy found by Webb telescope
Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That's because.....»»
Fast radio bursts: Research introduces a novel approach to characterize their behavior
Fast radio bursts (FRBs) represent the most intense radio explosions in the universe. Since the first discovery in 2007, FRBs have garnered significant attention, culminating in the 2023 Shaw Prize in Astronomy. With yet unknown origin, these extreme.....»»
NASA unveils probe bound for Jupiter"s possibly life-sustaining moon

Traces of DNA in the stomachs of predatory snails provide new insights into the ecology of placozoans
Placozoans are among the simplest animals and occur worldwide in coastal waters. It was previously assumed that the tiny creatures, which measure just a few millimeters, live either on hard surfaces—such as rocks, corals, and mangrove roots—or fl.....»»
ATLAS provides first measurement of the W-boson width at the LHC
The discovery of the Higgs boson in 2012 slotted in the final missing piece of the Standard Model puzzle. Yet, it left lingering questions. What lies beyond this framework? Where are the new phenomena that would solve the universe's remaining mysteri.....»»
Team is first ever to measure qubits with ultrasensitive thermal detectors, evading Heisenberg uncertainty principle
Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering......»»
If we want to visit more asteroids, we need to let the spacecraft think for themselves
Missions to asteroids have been on a tear recently. Visits by Rosetta, Osirix-REX, and Hayabusa2 have all visited small bodies and, in some cases, successfully returned samples to the Earth. But as humanity starts reaching out to asteroids, it will r.....»»
The sun was born when a dense gas cloud collapsed 4.6 billion years ago
While the upcoming total solar eclipse is a special moment to reflect on our place in the universe, scientists have been studying the birth of the sun and the formation of our solar system for a long time......»»
