Tiny, invisible gases long thought to be irrelevant in cloud formation may actually play a major role in determining whether clouds form—and possibly whether it rains. [...]
An enhanced version of Europe's Ariane 6 rocket will blast off Thursday to launch 32 satellites into orbit, forming part of the Amazon Leo network, which it hopes will rival Elon Musk's Starlink. [...]
The amount and accuracy of passing in the game of soccer—called football across much of the world—has climbed in recent years, according to new research. The average passing volume, pass accuracy, and the percentage of passes made rose in gameplay over the last five years, with the biggest changes occurring in women's competitions, according to an article posted to the arXiv preprint server from the Network Science Sports Institute, or NetSi Sport, a new research group out of Northeastern University's Network Science Institute. Gameplay has become faster and more intense, suggesting there is greater defensive pressure. [...]
Hunter-gatherers like the Hadza of Tanzania are famous for their egalitarianism. A resource redistribution experiment conducted with the Hadza suggests many tolerate inequality—as long as it benefits themselves. Published in PNAS Nexus, Duncan N.E. Stibbard-Hawkes, Kris M. Smith, and colleagues asked 117 Hadza adults to redistribute food resources between themselves and an unspecified campmate after receiving either advantageous or disadvantageous initial allocations. [...]
Accurate measurement of soil NO₃⁻-N is essential for precision fertilization and stable crop yields. Real-time monitoring of NO₃⁻-N has long been a challenge in agriculture. Conventional soil nutrient testing relies on time-consuming laboratory-based chemical analysis. Existing nitrogen monitoring technologies also have limitations regarding in situ deployment, temporal resolution, and continuous tracking. Furthermore, they are susceptible to interference from soil moisture, salinity, and complex field conditions. This makes them inadequate for the high-frequency, large-scale monitoring required by modern precision agriculture. [...]

The team included Professor Jongmin Kim of the Department of Life Sciences at POSTECH, along with graduate students Taeyang Heo, Dongwon Park, and Woosub Shin. [...]
When banks crowd a lending market, you can forget the traditional relationship of supply and demand, in which increased supply normally leads to lower prices. So finds new research from Cesare Fracassi, associate professor of finance at Texas McCombs. "Adverse Selection in Corporate Loan Markets" is published in The Journal of Finance. [...]
Researchers at the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo have developed a new inhalable form of tuberculosis (TB) treatment that could significantly reduce the burden of current therapy. Jessica L. Reynolds, Ph.D., associate professor of medicine in the Jacobs School, is senior author on the paper, titled "Repeated Pulmonary Dosing of β-Glucan-Chitosan-PLGA Nanoparticles Controls Mycobacterium Tuberculosis in Mice," published in Antimicrobial Agents and Chemotherapy. [...]
Building on their pioneering 2018 research into how some of the body's cells, such as neurons and cardiac tissue, communicate via ions that flow through cellular channels, chemists at the University of Massachusetts Amherst demonstrated a "leakiness" to a particularly mysterious type of channel, known as a "big potassium," or BK channel. This leakiness is key to further studies of the body's electrical infrastructure, which, when it goes haywire, can result in maladies like epilepsy and hypertension. [...]
From vaccines and diagnostics to emerging gene-based therapies, RNA molecules are now central to modern medicine. But as their use continues to grow, so does a fundamental challenge: producing RNA quickly, accurately and with the flexibility needed for next-generation biomedical applications. [...]
This stunning image from NASA's Hubble Space Telescope reveals a dramatic interplay of light and shadow in the Egg Nebula, sculpted by freshly ejected stardust. Located approximately 1,000 light-years away in the constellation Cygnus, the Egg Nebula features a central star obscured by a dense cloud of dust—like a "yolk" nestled within a dark, opaque "egg white." Only Hubble's sharpness can unveil the intricate details that hint at the processes shaping this enigmatic structure. [...]
Historically Black colleges and universities, often known as HBCUs, are well known for their deep roots in U.S. higher education and proven effectiveness at graduating Black students who go on to become professionally successful. [...]
Changes in the development finance world—especially the sharp drop in foreign aid and fewer cheap loans for low-income countries—have pushed taxation back into the spotlight. [...]
Do you know how you prefer to give and receive love? Do you need words of affirmation? Spending quality time? Acts of service? Gifts? Or physical touch? [...]
Cucumber is an economically important crop worldwide, ranking as the third most-produced vegetable after tomatoes and onions. Yet breeding improved varieties—plants that are more resilient, produce better-shaped fruit, or are less prone to hollowness—remains an enormous challenge. [...]
If the power goes out during a heat wave, there's nowhere more dangerous to be than where people spend most of their time—indoors. A new study led by researchers at The University of Texas at Austin is the first to assess the indoor heat vulnerability for each single-family home in an entire city. The research used Austin as its testbed, but the approach can be applied to most cities in the U.S. [...]
A recent study by researchers from Institute of Science Tokyo unveils the molecular mechanisms explaining why some "stealth" drug coatings fail to evade the immune system. Using single-molecule atomic force microscopy, the team measured how individual antibodies bind to poly (ethylene) glycol, showing that hydration and terminal chemistry strongly influence immune recognition. Their findings pave the way for novel drug coatings that stay effective longer by avoiding unwanted immune responses. [...]
Whether a smartphone battery lasts longer or a new drug can be developed to treat incurable diseases depends on how stably the atoms constituting the material are bonded. The core of molecular design lies in finding how to arrange these countless atoms to form the most stable molecule. Until now, this process has been as difficult as finding the lowest valley in a massive mountain range, requiring immense time and costs. Researchers at KAIST have developed a new technology that uses artificial intelligence (AI) to solve this process quickly and accurately. [...]
Growing up multiracial in the 1990s, Gabriel "Joey" Merrin regularly encountered demographic forms that forced an impossible choice: Pick one box. Deny the others. "That act of being forced to choose, to erase parts of myself from an official document, is at the core of this work," says Merrin, who is an assistant professor in the College of Arts and Sciences' Department of Human Development and Family Science. [...]
Pythons are a common sight across much of Asia, especially in the tropical jungles and wetlands of countries like Vietnam, Thailand and Indonesia. But one curious exception has been the main island of Taiwan, where there are none of these reptilian constrictors. So did they ever reach the island when sea levels were lower, or did they arrive and then vanish later? [...]
Every educator who teaches diversity might find this familiar. You mention "diversity, equity and inclusion" and the class responds in many different ways—some students are curious, others reflective, some unsure of what to expect next. [...]
If you're bilingual, moral choices can often feel more urgent and emotionally charged in one language yet distant and rational in another. This raises an intriguing question: does language merely shape how we express our thoughts, or can it also influence what we judge to be right or wrong? [...]
Most seals give birth to a pup around the same time each year, and wean them and send them on their way within 12 months in an annual cycle. [...]
As I walk into the classroom as a newly graduated teacher, I see children—each with unique abilities, interests and an eagerness to learn. This Ontario classroom was designed to be inclusive—a space where all students, regardless of their needs, can thrive. [...]
The global economy is bracing for major job disruption as artificial intelligence (AI) advances and spreads across industries.
