Researchers found a record-breaking number of eastern Pacific leatherback turtle nests in Ecuador during the 2025-2026 nesting season, more than 1,000 miles from their usual grounds. The study suggests leatherbacks are adapting to warmer ocean conditions by seeking new nesting sites in cooler regions.
Researchers have identified complement factor B as a promising target for pancreatic cancer treatment. Inhibiting this enzyme suppresses cancer growth, induces cellular senescence, and remodels the tumor immune microenvironment. The combination of CFB inhibition with chemotherapy and immunotherapy showed the greatest tumor suppression.

A new treatment approach combining immunotherapy with targeted cancer drug enfortumab vedotin improves survival in patients with muscle-invasive bladder cancer. The treatment reduces the risk of death by 42% and cancer recurrence or progression by 49% in patients unable to receive standard chemotherapy.
Researchers at Yale University have identified a key feature of how methane-eating microbes work, revealing a new nanowire machinery that helps them transfer electrons. This discovery sheds new light on the role of these microbes in the global methane cycle, potentially opening new avenues for methane conversion technologies.
New research suggests powerful ultraviolet light, like a cosmic leaf blower, could sweep away gas and dust in early galaxies, allowing stars to form at high rates. The study, published in The Astrophysical Journal, provides insights into the formation of bright galaxies in the early universe.
A new framework called Dark-2DGS combines photometric stereo priors with 2D Gaussian Splatting to reconstruct high-fidelity geometry from dark data. The method achieves higher geometric accuracy and visual quality compared to existing research results.
A new study analyzed over 180 million water measurements from the French long-term monitoring program
The podcast, hosted by Dr Ross Jenkinson and Dr Sam Patrick, ventures beyond their own field to explore topics such as AI, alien life, and cancer. The series puts a spotlight on postdoctoral researchers whose role at the forefront of scientific discovery can often be less visible to the public.
A 53-million-year-old beetle fossil, named Cnopus twentyonepilotorum, has been discovered in the Oise amber of northern France. The beetle's external morphology has remained remarkably stable over time, despite significant evolutionary changes.
A study from Trinity College Dublin found no association between community water fluoridation and cognitive decline in older adults. Researchers tracked fluoride exposure over a lifetime and tested cognitive function, concluding that lifetime exposure to fluoridated water is not linked to poorer cognitive function.
Researchers at King's College London developed BloomCalma, a pH-balanced intimate care product, using AI-assisted formulation design to create a microbiome-friendly gel for skin comfort during pregnancy and postpartum. The product is designed to soothe and hydrate intimate skin and is compatible with its natural microbiome.
Researchers have identified potential protein biomarkers in feline urine that could help detect and classify kidney disease early in cats, leading to better diagnoses and treatments. The study found three subgroups of proteins that could be used to classify different types of the disease.
A new Helmholtz Investigator Group led by Dr. Rima Schüssler will perform high-precision mass measurements on heavy, highly charged ions to test quantum electrodynamics and the Standard Model of particle physics. The team plans to use a Penning trap mass spectrometer at the HITRAP facility, which decelerates heavy ions to the point whe...
Researchers used AI to predict cavity risk by analyzing social determinants, enabling targeted public health programs. Wealth, household density, and water source were strong predictors of cavity risk, with non-White populations and private dental insurance showing protective effects.
A 65-year study of Gatineau Park leaves reveals the effects of Cold War nuclear testing have only recently disappeared from the local biosphere. The leaves, which act as a bioarchive, show a sharp increase in radiocarbon levels in the 1960s, peaking in 1964, and a decline that began around 2021-2022.
