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,
Many people are migrating within countries across South Asia to cope with extreme weather. In Bangladesh, Bhutan, India and Nepal, people often move from rural homes to urban metropolises when their homes and livelihoods become damaged or threatened by cyclones and storms,
Gold nanoparticles, which are about one-thousandth the width of a human hair, can convert light they receive from a laser into heat. This capacity, known in medicine as photothermal therapy, is effective at destroying cancer cells without harming the surrounding healthy tissue.

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:
How well do language models understand Meenzerisch, the dialect spoken in the German city of Mainz? A research team led by Johannes Gutenberg University Mainz (JGU) has now investigated this question for the first time. Meenzerisch still shapes regional language culture today
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
Economists have identified—and resolved—a seeming paradox regarding how competition from China affects the price and volume of products that are exported from other countries into the United States. The findings shed new light on the complex dynamics of international trade and
The practice of freediving is teaching physiologists how humans stretch their physical and mental limits, which in turn may improve treatments for lung and heart ailments.
A new European-led telescope could map the dusty, hidden half of the universe, all without using fossil fuels. If you have ever seen the Milky Way in the night sky, you probably noticed that it looks cloudy. That is because towards the center of our galaxy, and of most
When I first became co-director of an archaeological project at Jebel Barkal in northern Sudan in 2018, I was amazed by the site's pyramids, temples and palaces. It had been an urban center in the ancient empire of Kush, which dominated the Nile Valley off and on for more than
Formula 1 auto racing is one of the most energy-intensive and logistically complex sports on the planet. The events involve cars, of course, but also long-haul freight, international travel, temporary event infrastructure, and a global calendar that keeps people and equipment
A large-scale analysis of Grokipedia, the world's first AI-written encyclopedia, has found that while many Grokipedia articles closely resemble their Wikipedia counterparts, a substantial subset diverged markedly in style, sourcing and political leaning.
