Study finds water oversight failures at California dairies‎

A Stanford Law report reveals California's inadequate monitoring of dairies and feedlots, highlighting the need for stronger regulatory enforcement to protect groundwater quality and community health.

Largest known Mesozoic crocodyliform egg clutch discovered in Brazil‎

In a study published in the Journal of Vertebrate Paleontology, researchers Dr. Giovanna M. X. Paixão and her colleagues analyzed the fossilized remains of three Upper Cretaceous egg clutches. One of these clutches, totaling 47 eggs, is the largest known Mesozoic crocodyliform egg clutch ever found. The discovery indicates new evolutionary implications for one of the most diverse fossil crocodylomorph faunas, providing insight into their complex and successful reproductive habits and adaptations.

Material previously thought to be quantum is actually a new, non-quantum state of matter‎

Magnetic materials in a quantum spin liquid phase are of great interest in the pursuit of exotic state of matter and quantum computation. But in the quantum realm, things are not always what they seem. A study, published in Science Advances and co-led by Rice University's Pengcheng Dai, found that the material cerium magnesium hexalluminate (CeMgAl11O19) was not actually in a quantum spin liquid phase despite evidence suggesting it was.

What's inside neutron stars? New model could sharpen gravitational-wave 'tide' clues‎

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of any known objects, surpassed only by black holes. First observed in the 1960s, much of the internal composition of neutron stars is still unknown. Scientists are beginning to look to gravitational waves emitted by binary neutron‐star inspirals—pairs of mutually orbiting neutron stars—as possible sources of information about their interiors.

Villages: An underestimated habitat with potential for pollinators‎

When it comes to research on habitats for pollinating insects, villages have so far received relatively little attention. The project Summende Dörfer (Buzzing Villages), based at the Chair of Animal Ecology and Tropical Biology (Zoology III) at the Julius-Maximilians-Universität Würzburg (JMU), aims to change that. In the Würzburg region and the Rhön, researchers examined a total of 40 villages to investigate which habitats within village environments are particularly insect-friendly and species-rich—and where improvements could be made. The results have now been published in the journal Ecological Applications.

Many scientists now use AI but fail to disclose it, study finds‎

When scientists employ generative AI tools like ChatGPT to help with tasks such as editing and translation for their academic writing, many journals now ask them to disclose this assistance. The rules are intended to maintain transparency in scientific publishing. But many researchers are failing to acknowledge their reliance on these programs, according to a new report published in the journal PNAS. Yongyuan He and Yi Bu at the Department of Information Management, Peking University, analyzed more than 5.2 million papers published in 5,114 journals between 2021 and 2025.

Water-window X-rays without a synchrotron: How graphite flakes could shrink bioimaging tools‎

Researchers from Nanyang Technological University, Singapore (NTU Singapore) have found a new way to produce X-rays with wavelengths in what is called the "water window." This new method holds promise in making bioimaging X-ray machines smaller and more flexible to use.

Landowner trust and experience influence feral hog management, researchers find‎

Trust in others and prior experience with feral hogs were significant factors in whether landowners would commit effort and dollars to controlling the destructive animals, two studies have found.

Large area MoS₂ reduces energy loss in magnetic memory films‎

Scientists at the University of Manchester have discovered that placing magnetic films on atomically thin molybdenum disulfide (MoS₂) fundamentally changes how they lose energy, a finding that could bring 2D‑material spintronics a step closer to real devices. The team found that growing a widely used magnetic alloy, permalloy, on ultra‑thin MoS₂ alters the film's internal crystal structure, changing how and where energy is lost as magnetic spins move. By separating energy losses that occur at the surface of the film from those arising within its internal structure, the researchers provide new design insights for devices that use two‑dimensional (2D) materials to control magnetism more efficiently.

Simultaneously decoding the transcriptome, epigenome and 3D genome within a single cell‎

The origin of many diseases begins at the cellular level and involves multiple molecular interactions. However, previous methods have struggled to accurately observe changes in individual cells. Analyzing average values across thousands of cells made it challenging to detect the early signals of disease.
