Managing conflict between baboons and people: What's worked, and what hasn't

Conflict between humans and baboons can tear communities apart. Shirley C. Strum has studied wild olive baboons in Kenya for more than 50 years. In that time she's come to understand the species intimately. In this article she argues that humans have taken from nature (without asking) for too long. And that now it's time for us to rethink this relationship.

Microencapsulated B-vitamins help dairy cows produce more milk with fewer emissions

A new international study led by McGill University in collaboration with Jefo Nutrition shows that supplementing dairy cow diets with microencapsulated B-vitamins can significantly reduce greenhouse gas emissions while increasing milk yield and quality. The use of the feed additive cut global warming potential, an internationally standardized measure of climate impact, by up to 18% across seven countries.

Small galaxies may buck the black hole trend, Chandra finds

Most smaller galaxies may not have supermassive black holes in their centers, according to a recent study using NASA's Chandra X-ray Observatory. This contrasts with the common idea that nearly every galaxy has one of these giant black holes within their cores, as NASA leads the world in exploring the secrets of how the universe works.

Hidden fuel for ocean microbes: Urea emerges as key energy source for marine ammonia oxidizers

Ammonia-oxidizing archaea (AOA) are some of the most abundant microorganisms in the ocean and play a key role in nitrogen cycling. Yet, despite their ubiquity, scientists have long puzzled over how these microbes can flourish in the nutrient-poor waters of the open ocean, where their main nitrogen and energy source, ammonium, is often vanishingly scarce.

Astronomers create first map of the sun's outer boundary

Astronomers have produced the first continuous, two-dimensional maps of the outer edge of the sun's atmosphere, a shifting, frothy boundary that marks where solar winds escape the sun's magnetic grasp. By combining the maps and close-up measurements, scientists from the Center for Astrophysics | Harvard & Smithsonian (CfA) showed that the boundary grows larger, rougher and spikier as the sun becomes more active. The findings could help scientists improve models showing how the sun affects Earth, and better predict atmospheric complexity for other stars.

Unraveling the Complexity of Cancer-Related Cognitive Impairment in Breast Cancer

Cancer-related cognitive impairment (CRCI) is an important clinical problem that affects many patients with cancer and includes difficulties in memory, attention, processing speed, and executive function. Studies including patient-reported outcomes (PROs) suggest that 50% to 75% of patients receiving chemotherapy experience CRCI. These problems negatively affect daily functioning and can persist for many years. Given that CRCI exists in the short and long term, better understanding of the effect of disease and various treatment combinations on CRCI and whether there are differential effects in the magnitude of CRCI by treatment regimen and the contributions of host factors is needed.

The JWST just identified a supernova from only 730 million years after the Big Bang

Supernovae aren't one of the JWST's main science themes, but the perceptive telescope is full of surprises. Recently, it pinpointed a single star in a galaxy when the universe was only about 730 million years old. It wasn't just any random star; this one was a supernova responsible for a gamma-ray burst (GRB) detected back in March, 2025.

A new reference brain could make the clonal raider ant a go-to model species for neuroscience

Every clonal raider ant lives a nearly identical life. Each new generation of these blind, queenless ants is born at the same time, eats the same things, lives in the same environment, and—as an asexually reproducing species—has the exact same genes. It's hard to find a more textbook example of a society where the individual matters less than the collective.

Simulations reveal protein 'dynamin' constricts cell membranes by loosening its grip

Dynamin is a protein that plays a central role in endocytosis—the process where cells internalize substances by wrapping them in cell membrane vesicles. For a vesicle to detach, the neck of the membrane must be constricted and cut. Dynamin assembles into a ring shape around this neck and uses the energy from hydrolyzing GTP to change its shape and sever the membrane.

Eco-friendly, photo-switchable smart adhesives use biomass-derived materials

Conventional petroleum-based adhesives rely heavily on the petrochemical industry and pose environmental risks due to harmful emissions and limited reusability. In a new study, researchers developed a novel photo-switchable smart adhesive based on materials derived from rose oil. It is both eco-friendly and highly reusable, while exhibiting great adhesion to a variety of surfaces. This innovative adhesive paves the way for more sustainable and smart material technologies.

How building with Lego can help teens talk about life's big questions

If you're thinking about buying Christmas presents for children, chances are a Lego set isn't too far from your mind. The endless creativity that Lego bricks present means they can be used for far more than following instructions to build the model on the front of the box. They are even used in academic research.

Climate change puts riverbed microbes under constant stress, study finds

From tiny streams to gigantic rivers like the Mississippi—microbes in sediments work tirelessly to maintain key biogeochemical cycles. However, as temperatures rise, they tend to operate frequently in stress mode. This is the conclusion of an international study led by the University of Duisburg-Essen, which analyzed DNA and mRNA from 20 North American rivers. The results, recently published in the journal Microbiome, confirm patterns that have also been observed for European rivers.

Media hype shapes rise and fall of the 'girlboss' entrepreneur narrative

The girlboss is a cultural phenomenon created—and then deconstructed—by media hype. A study titled "The Rise and Fall of the Girlboss: Gender, Social Expectations and Entrepreneurial Hype" reconstructs the rise and fall of women entrepreneurs in media narratives. It shows how media portrayals have shaped society's expectations of female managers and helped to determine both their success and their downfall.

From FIFA to the LA Clippers, carbon offset scandals are exposing the gap between promises and reality

If you go to a pro sports event today, there's a good chance the stadium or arena will be powered at least in part by renewable energy. The team likely takes steps to reduce energy and waste. Some even claim to have net-zero greenhouse gas emissions, meaning any emissions they still do produce they offset by paying for projects, such as tree-planting, that reduce greenhouse gases elsewhere.

How are humans changing the Arctic Ocean?

As part of the EU project ECOTIP, an international team of researchers, including the Helmholtz-Zentrum Hereon, has analyzed the sea off Greenland more comprehensively than ever before. The key question: How is the area developing in the face of climate change and environmental pollution? Most of the samples were examined in the Hereon laboratories.
