The World Health Organization (WHO) regards antimicrobial resistance, including antibiotic resistance, as one of the world's major health challenges. A new fundamental understanding of antibiotic resistance could therefore potentially have a far-reaching impact on global public health, animal health and the environment.
The origins of the earliest life on Earth, prior to the rise of oxygen and photosynthesis, remain a mystery. Graveyards in brine pools at the bottom of the Red Sea may hold some answers.
Exoplanets are exotic worlds orbiting distant stars far beyond our solar system. Ever since the first ones were discovered in the 1990s, astronomers have turned their attention to these distant worlds to understand more about them. Now, for the first time, scientists have detected radio signals coming directly from one of these planets, a massive gas giant named β Pictoris b.
The fall equinox is Tuesday, when light and darkness split the day evenly. It marks the beginning of fall for the Northern Hemisphere and the beginning of spring in the Southern Hemisphere.
How much can we really trust a measurement? And how much data do researchers need to collect to draw reliable conclusions? Mohammad Reza Seydi at Umeå University has developed and tested new statistical methods to provide better answers to those questions.
Recent heat waves in Europe have been intensified by the greenhouse gases emitted since nations committed to limiting global warming under the 2015 Paris Agreement, according to a Sep. 22 study published in Geophysical Research Letters.
The ongoing El Niño is breaching the "super" threshold as Earth crosses into unprecedented climate territory. El Niño, officially underway as of June 11, is a climate pattern that's injecting extra heat into our already-warming world, threatening disruptive weather across the globe and a humanitarian crisis in some regions.While El Niño is part of a natural multiyear climate cycle, scientists have noticed that it has been rapidly strengthening like never before, intensified by human-driven climate change, and putting stressed natural systems under extra strain.In a new update this week, the National Oceanic and Atmospheric Administration's (NOAA) Climate Prediction Center continues to foreca...
Researchers have developed an organoid-on-a-chip technology that verifies the efficacy of Parkinson's disease treatments in real time. The technology combines a stem cell–derived "mini-brain" with a nanoplasmonic sensor engineered to maximize light–matter interaction.
More and more details about 3I/ATLAS are filtering through the scientific process as time goes on. Our third known interstellar visitor attracted the attention of some of the world's most powerful observatories when it was discovered in July 2025, and some of those telescopes found something peculiar—the isotopes it contained appeared different. A new paper submitted to The Astrophysical Journal Letters (and available as a preprint on arXiv) by Kenji Furuya of the RIKEN Pioneering Research Institute in Japan and his co-authors shows that the isotopic discrepancy is likely due to the "low metallicity" of the stellar nursery in which 3I/ATLAS was born.
The newest “Dragon Hatchling” AI model is testing whether skipping words in intermediate reasoning could cut computational cost.
The president also said artificial intelligence should be rebranded as “super intelligence”
Scientists have identified a "sweet spot" in Earth's deep past when conditions were optimal for a proposed early stage of life to take hold — a phase known as the RNA World.The sweet spot was 4.33 billion years ago, although Earth may have become suitable for the RNA World as early as 4.4 billion years ago, given that extreme bombardment by asteroids, comets and other rocky leftovers of planet formation had largely stopped by then, the researchers reported in a study published Tuesday (Sept. 22) in the journal Nature Communications.The findings give a more precise estimate of the RNA World's onset than previous studies based on geochemical modeling, biomolecular analyses and simulations of e...
