An international team has described Foskeia pelendonum, a tiny Early Cretaceous ornithopod from Vegagete (Burgos, Spain), measuring barely half a meter long. Led by Paul-Emile Dieudonné (National University of Río Negro, Argentina), the study reveals an unexpectedly derived skull and positions Foskeia near the origin of the European herbivorous lineage Rhabdodontidae. The study is published in Papers in Palaeontology. [...]
Extracellular vesicles and particles are central to how cells communicate, especially in cancer, where they help shape metastasis and treatment resistance. However, most existing methods analyze vesicles in bulk, masking differences between individual cells. Some single-vesicle techniques offer particle-level detail but lose information about the cell that produced them. Other single-cell platforms face practical limits, such as short culture times or signal mixing between cells. These limitations make it difficult to study how individual cells behave over time. Based on these challenges, there is a clear need for technologies that can culture single cells long-term while isolating and analyzing the vesicles each cell produces. [...]
New research from the University of St Andrews has discovered a crucial piece in the puzzle of how all animals with a spine—including all mammals, fish, reptiles and amphibians—evolved. In a paper published in BMC Biology, researchers found an intriguing pattern of gene evolution which appears to be significant for the evolutionary origin and diversification of vertebrates. [...]
A recent satellite-based study has uncovered alarming declines in groundwater storage across High Mountain Asia (HMA), widely known as the "Asian Water Tower." This critical water source, which sustains agricultural irrigation, urban water supplies and ecological security for hundreds of millions of people in more than a dozen downstream countries, is depleting at a staggering rate of approximately 24.2 billion tons per year. [...]
Three years ago, Penn Vet researchers reported a major breakthrough in equine assisted reproduction. Katrin Hinrichs, Harry Werner Endowed Professor of Equine Medicine, and colleagues developed a technique that would allow successful conventional in vitro fertilization (IVF) with horses. In conventional IVF, the sperm does its job of finding and fertilizing a mare's egg, or an oocyte, in a Petri dish. Developing a method to motivate stallion sperm to do this—let alone do it consistently—had eluded researchers for decades. [...]
The oxygen reduction reaction (ORR) is a key process in fuel cells and metal-air batteries, technologies expected to play a central role in a low-carbon energy future. However, ORR proceeds slowly on most materials, limiting efficiency and increasing costs. Finding catalysts that can speed up this reaction is therefore a major challenge in reducing our energy footprint. [...]

A perspective in the Journal of the Royal Society Interface argues that advances in AI, sensing technologies and modeling are transforming the study of collective animal behavior, with implications reaching far beyond biology, from robotics to the dynamics of human crowds. [...]
The Barrow-in-Furness accent is very different from the rest of Lancashire and Cumbria because of an intense mixing and rapid population change in the late 1800s, says new research by Lancaster University, which used the voices of Victorian speakers to inform the study. [...]
Around 540 million years ago, Earth's biosphere underwent a pivotal transformation, shifting from a microbe-dominated world to one teeming with animal life, as nearly all major animal phyla appeared abruptly in the fossil record over a very short geological time interval. This landmark evolutionary event is known as the Cambrian Explosion. [...]
When it comes to global warming and climate change, we often hear news stories about tipping points where Earth's systems shift into a new and dangerous state. One such may have been reached in the year 2000 that caused tropical weather cycles to have a greater effect on autumn sea ice melt across the Laptev and East Siberian seas, according to a study published in Science Advances. [...]
In a study conducted by Dr. Mahdi Alirezazadeh and Dr. Hanan Bahranipoor, published in Archaeological Research in Asia, two exceptionally well-preserved fetal burials from Chaparabad, Iran, dating to the mid-5th millennium BC, were analyzed including burial L522.1, one of the most complete prehistoric infant burials in the Iranian plateau. Despite being buried only meters apart, the two fetal burials exhibit distinct burial treatments, offering insights into the variable burial practices of prehistoric cultures in southwestern Asia. [...]
Dangerous concentrations of algae such as "red tides" have been consistently emerging in locations around the world. A region in Southern Australia is experiencing a nine-month toxic algae bloom that spans thousands of miles and has caused thousands of deaths across marine species. Such harmful algal blooms (HABs) produce toxins that can force municipalities to close beaches and lakes due to public health risks. [...]
Ditches and canals are the underdog of the freshwater world. These human-made waterways are often forgotten, devalued, and perceived negatively—think "dull as ditchwater." But these unsung heroes have a hidden potential for climate change mitigation, if they're managed correctly. [...]
A new study finds that Canada could remove at least five times its annual carbon emissions with strategic planting of more than six million trees along the northern edge of the boreal forest. The paper, "Substantial carbon removal capacity of Taiga reforestation and afforestation at Canada's boreal edge," appears in Communications Earth & Environment. [...]
In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner crystal state remains sensitive to various experimental perturbations. Uncovering their internal structure and arrangement at the atomic scale has proven more challenging. [...]
Travel misery was set to continue Sunday as a powerful snowstorm blasted southern US states, bringing subzero temperatures to regions not accustomed to the deadly winter conditions. [...]

A report published today by the Williams Institute at UCLA School of Law shows that 53% of transgender youth between the ages of 13 and 17 in the U.S.—approximately 382,800 young people—live in 29 states with laws or policies that restrict their access to gender-affirming care, sports, bathrooms and facilities or restrict the use of gender-affirming pronouns in schools. [...]
Blue carbon refers to organic carbon captured and stored by the marine and vegetated coastal ecosystems such as mangrove forests, salt marshes, and seagrass meadows. These ecosystems act as powerful carbon sinks, sequestering carbon from the atmosphere efficiently like terrestrial forests. [...]
Across large parts of northern Tanzania, gully erosion—soil erosion caused by flowing water—is cutting deep scars through fertile farmland, grazing areas, roads and even villages. These gullies grow faster every year and what was once a slow environmental process has accelerated into a humanitarian threat. It has serious consequences for food and livelihood security, infrastructure and biodiversity. [...]
While most of us value honesty, we consider those who skew reality to avoid hurting others to be more moral. Despite that, we prefer to hear the harsh truth when the feedback concerns us, according to a study conducted by psychologists from SWPS University and the University of Wrocław. [...]
Community-engaged research often raises questions about who benefits from academic work and how knowledge moves between universities and the people most affected by the issues being studied. In his research and film projects, Kirk French, an assistant professor of anthropology and of film production and media studies at Penn State, works with communities as collaborators rather than subjects, shaping research questions, methods and outcomes alongside local partners.
