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 keep global warming below the 1.5–2 degrees Celsius targets set by the Paris Agreement. Because of this, researchers are exploring climate intervention strategies as possible additions to emissions cuts. [...]
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 in 3D with near-atomic resolution. [...]
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 against a rare and often deadly fungal infection called mucormycosis. The study is published in Nature. [...]
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 biology. [...]
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 be found. [...]
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 historically been represented in science—including many people of color, LGBTQ+ and first-generation scientists—identity is intertwined with how they engage in and share their work. [...]
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. [...]
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 the universe worked at its most fundamental level. [...]
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. [...]
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 unattainable. [...]
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 Duke-NUS Medical School discovered how exercise helps aging muscles regain their ability for self-repair. [...]
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. [...]
President Donald Trump's administration is finalizing its repeal of a foundational scientific determination that underpins the US government's authority to regulate greenhouse gas emissions, with an announcement expected in the coming weeks. [...]
The world's first legally binding agreement to protect marine life in international waters took effect Saturday, marking a historic moment for ocean conservation after nearly two decades of negotiations. [...]
NASA's giant new moon rocket headed to the launch pad Saturday in preparation for astronauts' first lunar fly-around in more than half a century. [...]
Scientists at the University of Illinois Urbana-Champaign can now differentiate between human-derived and hydrological contributions of riverine nitrogen pollution in the Upper Mississippi River Basin. The advancement, published in Environmental Science and Technology, sets the stage for more nuanced policy and management of nitrate and nitrite, the nutrients that degrade drinking water quality and cause oxygen-starved "dead zones" in the Gulf each year. [...]
A new study shows that increasing production on farms and reducing emissions can go hand-in-hand, with researchers finding that improved farm productivity has been the driving force in keeping greenhouse gas emissions from agriculture in check. [...]
