Most students use AI—but their attitudes toward it are ambivalent. On the one hand, they see it as helpful for working more efficiently, broadening their knowledge, and overcoming writing difficulties. On the other, they worry about becoming overly dependent on it and losing
RNA is the means of translating the genetic code embedded in DNA into proteins, which serve as enzymes, transporters, signaling molecules, receptors, structural components, regulators, and gene-expression controllers, among many other roles. Yet one gene is not limited to
The 2026 Atlantic hurricane season starts June 1, and while a developing El Niño might result in a tamer season than in the past few years, all it takes is one big storm hitting a populated area to make it a bad hurricane season.
Some birds sing to attract a mate. Others dance or display colorful feathers. But in the moonlit forests and shrublands of northern Argentina, one bird courts romance by snapping its wrists together, producing a sharp clapping sound scientists have puzzled over for decades.
Researchers at Bar-Ilan University have successfully restored youthful patterns of DNA organization in the livers of old mice, reversing key molecular features associated with aging. The study, published in Nature Communications, identifies the protein SIRT6 as a powerful

In the HiPEQ project, a consortium of industry and research partners has developed new laser-based approaches to enable miniaturized, robust beam sources for quantum technology. Among others, the consortium also used lasers to grow novel optical insulator crystals. The project
Governments around the world conserve plants and animals in part by setting aside land. Whether as wilderness reserves or as resource management zones that allow industrial activities such as logging, 17.4% of the planet's land offers some measure of protection. These protected
A review paper led by researchers from the University of St Andrews highlights the transformative potential in the use of radar in polar research to predict future sea levels.
Today's computers store information using only two values: 0 and 1. But as electronic devices become smaller and reach their limits, scientists are searching for new ways to pack more information into the same space. One idea is to use magnetism. In some materials, atoms behave
Cows eat grass...everyone knows that. But climate change is forcing producers and scientists to rethink some of our long-held assumptions about livestock nutrition. Crop costs are climbing. Traditional pastures are under pressure. And researchers are casting a wider net for
Service quality improvement requires a holistic approach to analyzing customer reviews and identifying relevant, actionable issues. Researchers from South Korea have addressed this by developing a model that integrates service-specific aspects and customer actions, which are
Is the next generation of college graduates justified in jeering at the coming industrial revolution? The post Commencement Boos for AI Platitudes appeared first on Nautilus .
A team at the University of Vienna, led by chemist Nuno Maulide, has developed a new method for controlling chemical reactions in a more targeted and efficient manner. At the heart of this is the concept of "cation sampling": specially selected groups (ketones), in a sense,
Rates of violence against women have remained largely unchanged in California for nearly two decades, with Black and multiracial women facing the highest risks, a sweeping new analysis by UC Berkeley public health researchers has found.
Parasitic nematodes (commonly known as roundworms) are a large, diverse and poorly studied group of disease-causing organisms that severely impact the health of humans and animals. They infect almost one-quarter of the global population and significantly impair child growth and
Researchers at the University of California, Los Angeles (UCLA) have developed a novel image projection system that delivers super-resolution images over an extended depth of field. By combining a neural network-based digital encoder with a passive all-optical diffractive
Florida State University chemists have synthesized new molecules derived from bacteria found in a Pacific Ocean sea sponge, a breakthrough for the future of drug development, particularly for rare forms of cancer.
In a new study, researchers show how so‑called TriPcides can target the bacterium Staphylococcus aureus, including antibiotic‑resistant strains such as MRSA. The compounds disrupt the bacteria's ability to cause infection and can also kill dormant bacterial cells, which are
Why do so many corporate renewal efforts fail, despite following current best practices?
March was a scorching 9.35 degrees Fahrenheit hotter than the 20th-century average for the month, capping the hottest 12-month stretch for the U.S. since records began in 1895
More than half the world's population now lives in cities that are often much hotter than their rural surroundings. Roads, buildings and paved surfaces absorb and store heat during the day, then release it slowly after sunset. This is known as the urban heat island effect.
An international team of scientists has developed a new analysis of how sound waves behave, revealing surprising effects that have largely been overlooked for decades. In the new paper in Scientific Reports, which was led by researchers from City St George's, University of
Cellular membranes not only constitute a barrier, but they also accommodate a plethora of different molecules for sensing and ensuring cellular function. These molecules often cluster together, forming condensates embedded in the membrane. A team of physicists from MPI-DS
Scientists at Children's Medical Center Research Institute at UT Southwestern (CRI) have discovered that large pieces of DNA can transfer directly between human cells, and the DNA can persist and change how the recipient cell functions. The findings, published in Cell,

Quantum technologies promise powerful new kinds of computers, giving scientists new tools to mimic and explore nature at its tiniest scales. At those levels, everything in nature—from atoms and electrons to light itself—follows the strange rules of quantum mechanics. But the
We often assume that how we respond to a rude comment says something stable about us: our personality, our culture, even the language we are speaking. If someone reacts calmly, we presume they are a patient person. If they snap back, we might assume they are short-tempered.
What happens when a scientific problem seems too complex to solve precisely, yet understanding it could reshape how researchers design new materials and medicines? For decades, much of the polymer science community has relied on a "good enough" approach to a stubborn problem:

You skip the pesticides, you remove weeds by hand, you choose heirloom seeds. Organic methods give you comfort in knowing that your vegetables are grown without excessive chemicals.
For decades, historians have generally agreed that the progress of small villages as they evolved into cities came at the price of widening inequality. A small group of leaders, kings and priests, would inevitably seize control of the wealth and the gap between rich and poor
Scientists at VIB and Vrije Universiteit Brussel have uncovered a previously unknown mechanism that helps a widely used biological pesticide become more effective. The study, published in Nature Communications, reveals how bacteria produce ultra-strong protein fibers that form
