A mysterious bar-shaped cloud of iron has been discovered inside the iconic Ring Nebula by a European team led by astronomers at University College London (UCL) and Cardiff University.
Opinion polarization is often considered as the primary driver of social friction, leading to exhaustive efforts to force a consensus. However, new research suggests a more pragmatic goal: reducing the friction of disagreement without necessarily eliminating the diversity of
Growing up in Greece, wildfires were a constant presence each summer. In 2007, I remember watching TV footage of fires ravaging the Peloponnese peninsula and island of Evia, destroying forests and homes, taking lives. The sight of helicopters and firefighting aircraft crossing
People shouldn't be afraid to say what they think, and new research from the University of Virginia bears that out.
As Earth warms due to climate change, oceans are heating up, becoming more acidic, and losing oxygen. These changes threaten marine life, food webs, and global fisheries. Scientists agree that cutting greenhouse gas emissions is essential, but current efforts are not enough to
A Purple Star Sapphire weighing 3,563 carats which is claimed to be the world's biggest of its kind was unveiled on Saturday in the Sri Lankan capital by the owners, who are ready to sell the precious stone which is estimated to be worth at least $300 million.
Indigenous communities have lived with changes to the climate for centuries. Their adaptations over those many years are based on their close observation of weather, water, soils and seasonal change, and they have been refined through generations of learning.
Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons that emerge allow researchers to reconstruct the internal architecture of a cell
Intrinsic water-use efficiency (iWUE) reflects how efficiently plants assimilate carbon relative to water loss at the leaf level. While widely studied using carbon isotope and gas-exchange measurements, most existing knowledge is derived from local observations.
UK inflation may be easing, but many households still find their weekly shop getting more expensive. One key reason is something not captured in headline prices: shrinkflation, where manufacturers reduce pack sizes without reducing the price.
Researchers at Colorado State University have determined how to use artificial intelligence to modify antibodies so they act as lightbulbs, enabling scientists to better see inside living cells to track errors in gene expression that can lead to cancer and other disorders.
Scientists at the Institute of Molecular Biology and Biotechnology (IMBB-FORTH) and the University of Crete, together with collaborators from Greece, Europe, the U.S., and India, have discovered a novel role of albumin, the most abundant protein in human blood, in protecting
Understanding human gene function in living organisms has long been hampered by fundamental differences between species. Although mice share most protein-coding genes with humans, their regulatory landscapes often diverge, limiting how accurately mouse models can mimic human
Curtin University researchers have demonstrated a new way to uncover the ancient history of Australia's landscapes, which could offer crucial insights into how our environment responds to geological processes and climate change and even where deposits of valuable minerals may
Low-income and ethnically diverse communities in post-industrial Northern English cities face up to 33% more air pollution than their neighbors in wealthier areas, according to new University of Sheffield research.

Lived experiences shape how science is conducted. This matters because who gets to speak for science steers which problems are prioritized, how evidence is translated into practice and who ultimately benefits from scientific advances. For researchers whose communities have not
Wearable health care devices—such as glucose monitors, ultrasound patches and blood-pressure monitors—can be invaluable for keeping patients safe.
Many natural compounds that act on the human body provide active ingredients for medicines or clues for developing them, and they play a crucial role in pharmaceutical research.
MicroRNAs, whose discovery was recognized with the 2025 Nobel Prize in Physiology or Medicine, are central regulators of gene expression, yet a fundamental question has remained unanswered: how cells choose between the two strands produced from each microRNA precursor.
Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” the team can produce ultra-fast surface waves that already play a hidden role in smartphones,
At first glance, some scientific research can seem, well, impractical. When physicists began exploring the strange, subatomic world of quantum mechanics a century ago, they weren't trying to build better medical tools or high-speed internet. They were simply curious about how
One intriguing method that could be used to form the qubits needed for quantum computers involves electrons hovering above liquid helium. But it wasn't clear how data in this form could be read easily.
Researchers from IMDEA Materials Institute have demonstrated improved and more affordable catalytic materials used to produce green hydrogen.
Our prehistoric human ancestors relied on deliberately modified and sharpened stone tools as early as 3.3 million years ago. The selection of rock type depended on how easily the material could be flaked to the desired shape and form.
New research looks at the effects of spaceflight on biological age The post Spaceflight Prematurely Ages Astronauts appeared first on Nautilus .
Thyme extract is packed with health-promoting compounds, but it is difficult to control and easy to waste. Researchers created a new technique that traps tiny amounts of the extract inside microscopic capsules, preventing evaporation and irritation. The method delivers
NASA rolled out the fully stacked Artemis II rocket and Orion capsule on Saturday, embarking on a four-mile journey to the launch pad
Researchers have turned artificial intelligence into a powerful new lens for understanding why cancer survival rates differ so dramatically around the world. By analyzing cancer data and health system information from 185 countries, the AI model highlights which factors, such
Horses can smell your fear. If you are experiencing this emotion while standing near a horse, they will be able to detect it through your scent alone, which changes their behavior and physiology. That's the conclusion of a new study published in the journal PLOS One.
Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation or required cryogenic cooling, making continuous room-temperature operation
Cancer is a leading cause of death in both humans and pets; studies suggest that between one-third and one-half of all dogs will develop cancer during their lifetime.
This week, a new analysis of Jupiter's atmosphere estimated that the gas giant has 1.5 times more oxygen than the sun. Researchers in Brazil identified a protein that allows pancreatic cancer to infiltrate nerves and spread early in the course of the disease. And scientists at
What will the climate of a given region be like in 20, 30 or 50 years? Climate analogs provide a robust methodological framework to address this question by identifying regions whose current climate matches the future climate of another area.
