Why AI language models choke on too much text
Compute costs scale with the square of the input size. That's not great. Large language models represent text using tokens, each of which is a few characters. Short words are repr.....»»
Simulations of hominin Lucy help show how long distance running evolved in modern humans
A team of natural scientists, musculoskeletal specialists, and evolutionary biologists affiliated with several institutions in the U.K., working with a colleague from the Netherlands, has found via simulations, that the famous early hominin Lucy, cou.....»»
Latest gravitational wave observations conflict with expectations from stellar models
Almost 300 binary mergers have been detected so far, indicated by their passing gravitational waves. These measurements from the world's gravitational wave observatories put constraints on the masses and spins of the merging objects such as black hol.....»»
Growing safer spuds: Removing toxins from potatoes
Scientists have discovered a way to remove toxic compounds from potatoes, making them safer to eat and easier to store. The breakthrough could cut food waste and enhance crop farming in space and other extreme environments......»»
Gateway: Wired for deep space
A maze of cables and sensors snakes through a major piece of Gateway, humanity's first space station around the moon, during a key testing phase earlier this year to ensure the lunar-orbiting science lab can withstand the harsh conditions of deep spa.....»»
Chang"e-6 farside basalts reveal a reinforced lunar dynamo
The evolution of the lunar dynamo is crucial for understanding the moon's deep interior structure, thermal history, and surface environment. A study by Chinese scientists conducted paleomagnetic analyses on basalts returned by the Chang'e-6 mission a.....»»
Miniature sensor that detects toxic gas shows promising results in the lab
A team of scientists at UNSW Sydney have developed a highly sensitive miniature sensor that is able to detect low levels of the toxic gas nitrogen dioxide (NO2). The tiny, flexible sensor can detect the harmful gas in real-time without requiring an e.....»»
Russia-Ukraine War"s unexpected casualties: Hungry people in distant nations
The war in Ukraine is causing hunger thousands of miles from the battlefields, according to a study in Communications Earth & Environment. Nearly three years of war in the "breadbasket of the world" has left croplands destroyed and forced laborers wh.....»»
Apple stops signing iOS 18.1.1, blocking downgrade from 18.2
Apple on Thursday stopped signing iOS 18.1.1, preventing users from downgrading to this version of the operating system if their iPhone or iPad is already running a newer version. The move comes a week after the release of iOS 18.2, which introduced.....»»
Clever trick to cook young stars detected for first time—astronomers highlight magnetic fields as the missing ingredient
The missing ingredient for cooking up stars in the same way you might steam your Christmas pudding has been spotted for the first time by astronomers. Much like a pressure cooker has a weight on top of its lid to keep the pressure in and get your fes.....»»
Not to be outdone by OpenAI, Google releases its own “reasoning” AI model
Gemini 2.0 Flash Thinking is Google's take on so-called AI reasoning models. It's been a really busy month for Google as it apparently endeavors to outshine OpenAI with a blitz of.....»»
Study reveals flies more vulnerable than bees to climate change
Despite their reputation as buzzing nuisances, flies serve a critical role as some of the Earth's most prolific pollinators—and new research led by Penn State scientists suggests they are increasingly at risk due to rising global temperatures......»»
Environmental groups challenge update to California"s low-carbon transportation rules
A coalition of environmental groups challenged California's leading climate regulator on Wednesday, alleging that a recent update to a leading climate program will create additional pollution in the state's San Joaquin Valley......»»
Plasma heating efficiency in fusion devices boosted by metal screens
Heating plasma to the ultra-high temperatures needed for fusion reactions requires more than turning the dial on a thermostat. Scientists consider multiple methods, one of which involves injecting electromagnetic waves into the plasma, the same proce.....»»
Newly identified mysterious fossil seed reveals Ice Age climate patterns
La Brea Tar Pits scientists have identified a previously unknown juniper species as Juniperus scopulorum, commonly known as the Rocky Mountain Juniper. The successful identification, along with the first-ever radiocarbon dating of these fossil plants.....»»
Scientists achieve collective quantum behavior in macroscopic oscillators
Quantum technologies are radically transforming our understanding of the universe. One emerging technology is macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in telecommunications. In the q.....»»
Molecular tool demonstrates how bad eggs are identified for destruction by reproductive system
The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs with chromosomal abnormalities. For years, cell biologists have sought to uncover the mechanisms behind this system, relying on.....»»
Need to accurately measure time in space? Use a COMPASSO
Telling time in space is difficult, but it is absolutely critical for applications ranging from testing relativity to navigating down the road. Atomic clocks, such as those used on the Global Navigation Satellite System network, are accurate, but onl.....»»
Climate change could trigger more earthquakes, study suggests
A recent Colorado State University study published in the journal Geology demonstrates that climate change can affect the frequency of earthquakes, adding to a small but growing body of evidence showing that climate can alter the seismic cycle......»»
Apollo lunar mission samples reveal origins of lunar water and its connection to Earth"s early history
A team of international scientists has unveiled groundbreaking research on the origins of lunar water, offering insights that could reshape our understanding of the Earth-moon system and the broader solar system. Published in the journal Proceedings.....»»
