Galaxies bigger than ours appear less than a billion years after the Big Bang. Enlarge (credit: NASA, ESA, CSA, and STScI) How soon after the Big Bang could stars and galaxies start to form? It has been a difficult quest.....»»
Oil pollution in North Sea is "grossly underestimated," suggests new report
Growing up in Aberdeen, Scotland, the shadow of the Piper Alpha disaster loomed large over our community. The tragic explosion of the oil rig platform in 1988 claimed the lives of 167 people. Back then, I was blissfully unaware of the ecological rami.....»»
Precise locations of more than 1 million galaxies revealed
The Physics of the Accelerating Universe Survey (PAUS), an international collaboration across 14 institutions, has covered a sky area of 50 square degrees, similar to approximately 250 full moons......»»
Saturday Citations: Octopuses as shift supervisors for fish; universe confounds standard model; extremely old cheese
This week, biologists tracked down a mysterious group of orcas near Chile; Hubble spotted a black hole jet that causes stars along its trajectory to erupt; and researchers explained mysterious craters that began appearing in Siberian permafrost in th.....»»
New approach reveals details about aerosol properties from hard-to-sample areas in the atmosphere
The spatial distribution of ambient aerosol particles plays a huge role in aerosol–radiation–cloud interactions; however, not enough sampling has been done from the atmospheric boundary layer and lower free troposphere. This leaves large gaps in.....»»
How large language models are changing collective intelligence
Within teams, organizations, markets and online communities, ideas from a larger group can help to solve complex problems. Large language models (LLMs) are emerging as powerful tools to unlock even greater potential. Picture an online forum where tho.....»»
Advanced data shed light on gravitational basins of attraction that shape the movement of galaxies
A new study has mapped out the gravitational basins of attraction in the local universe, offering fresh insights into the large-scale cosmic structures that shape the movement of galaxies. The study has been published in Nature Astronomy......»»
Grocery stores that donate expiring food instead of price discounting or discarding make higher profits, says researcher
All major supermarkets and retailers that sell groceries, such as Kroger, Walmart and Costco, give large amounts of food to food banks and pantries. In 2022, retailers donated close to 2 billion pounds of food across the United States, which amounted.....»»

Scientists create model of holographic dark energy that is no longer unstable
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time but is impossible to.....»»
OpenAI drops nonprofit status in large-scale reorganization
OpenAI is reportedly planning to scrap the nonprofit structure of its core business in favor of a for-profit model that will be more attractive to investors......»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
Small firms may offer higher pay due to a lack of market power
Small companies may post higher wages for entry level positions than large companies—potentially attracting better talent, even though the larger companies have more influence on the market, according to new Cornell research......»»
A versatile approach to realize quantum-enhanced metrology with large Fock states
The collecting of highly precise measurements can enable research developments and technological advancements in numerous fields. In physics, high-precision measurements can unveil new phenomena and experimentally validate theories......»»
Can the "hard steps" in the evolutionary history of human intelligence be recast with geological thresholds?
What took so long for humans to appear on Earth? The Earth is 4.6 billion years old, and life began about 4 billion years ago, yet humans—the only intelligent, technological species we know of in the universe—have existed only for the last 200,0.....»»
Walking on the Moon in Cologne: Europe"s lunar life simulator

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.....»»
Microchip can save millions of liters of milk from going down the drain
Large amounts of the food we produce do not end up in our stomachs, but in landfills, sewers, or elsewhere. According to the UN, in 2022, this was the fate of 1.05 billion tons of food, which ended up as food waste—corresponding to approximately 13.....»»
