Astronomers carry out largest ever cosmological computer simulation
An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as planets, stars and galaxies), giving us a glimpse into how our uni.....»»
New report details what happened to the Arecibo Observatory
In 1963, the Arecibo Observatory became operational on the island of Puerto Rico. Measuring 305 meters (~1000 ft) in diameter, Arecibo's spherical reflector dish was the largest radio telescope in the world at the time—a record it maintained until.....»»
Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
Astronomers use JWST and ALMA to explore the structure of a giant spiral galaxy
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational campaign, published Oc.....»»
AI-driven mobile robots team up to tackle chemical synthesis
Researchers at the University of Liverpool have developed AI-driven mobile robots that can carry out chemical synthesis research with extraordinary efficiency......»»
Anthropic’s Haiku 3.5 surprises experts with an “intelligence” price increase
Anthropic’s smallest AI model now beats its older largest LLM, Opus, at some tasks. On Monday, Anthropic launched the latest version of its smallest AI model, Claude 3.5 Haiku,.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
The M4 Mac mini could be the best offer Apple has ever made PC switchers
The M4 Mac mini arrives this Friday. The tiny, redesigned computer packs a lot of power, and with a low . All of which makes me think: this may be the best offering Apple has ever had for PC switchers. Here’s why. more….....»»
Defibrillation devices can still save lives using 1,000 times less electricity, optimized model finds
In a paper published in Chaos, researchers from Sergio Arboleda University in Bogotá, Colombia, and the Georgia Institute of Technology in Atlanta used an electrophysiological computer model of the heart's electrical circuits to examine the effect o.....»»
Globular cluster Gran 5 hosts two stellar populations, study finds
Using the Gemini-South telescope, astronomers have performed high-resolution near-infrared spectroscopy of stars in a Galactic globular cluster known as Gran 5. They found that this cluster harbors two stellar populations with different metallicities.....»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
Unlocking next-gen chip efficiency: Researchers confirm thermal insights for tiny circuits
In a leap toward more powerful and efficient computer chips, researchers at the University of Virginia have confirmed a key principle governing heat flow in thin metal films—a critical component in the race to design faster, smaller and more effici.....»»
Dams have taken half the water from Australia"s second biggest river—and climate change will make it even worse
The largest wetland on Australia's second longest river, the Murrumbidgee in the southern Murray-Darling Basin, is drying up. This is bad news for the plants, animals and people who rely on the vast Lowbidgee Floodplain. So it's important to understa.....»»
Computer modeling research reveals the changing history of a global ice sheet
Imagine that a massive ice sheet covered Canada and oozed down over a large part of the northern United States, like icing spilling down the side of a cake. That was the situation somewhere between 19,000 and 26,000 years ago. The ice sheet covered l.....»»
Observations detect hundreds of possible supergiant stars in two nearby galaxies
Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in a research paper published O.....»»
Fossil of huge terror bird offers new information about wildlife in South America 12 million years ago
Researchers including a Johns Hopkins University evolutionary biologist report they have analyzed a fossil of an extinct giant meat-eating bird—which they say could be the largest known member of its kind—providing new information about animal li.....»»

Learning more about supernovae through stardust
Most of the diverse elements in the universe come from supernovae. We are, quite literally, made of the dust of those long-dead stars and other astrophysical processes. But the details of how it all comes about are something astronomers strive to und.....»»

California"s Salton Sea receding at greater rate according to balloon mapping study
The Salton Sea, California's largest lake by surface area, is experiencing an increasing rate of shoreline retreat following a policy change that shifted more water from the Colorado River to San Diego, according to a newly published study. The resul.....»»
