From simulation to strategy: Climate modeling motivates action at the top‎

New research by MIT Sloan School of Management finds that global leaders who participate in facilitated engagements using an interactive climate policy simulator, En-ROADS, demonstrated a stronger understanding of climate solutions, felt more personally connected to the issue, and were more likely to take climate-related action or advocate for change in their governments, businesses, organizations, or communities. Most reported that the interactive aspects of simulations enhanced learning compared to conventional, more passive approaches.

Study in search of a tropical spring is first to show some birds flip their breeding season in response to climate‎

In 2014, Felicity Newell joined the Florida Museum of Natural History as a doctoral student, then promptly left the country in search of a tropical spring. It's a concept she started thinking about while doing biological surveys in Honduras. There, a colleague told her about the work of Alexander Skutch, a renowned ornithologist who spent 20 years studying the breeding habits of birds in Costa Rica. Based on this work, he became "convinced that the birds … have a definite nesting season, and its beginning coincides with the return of spring."

From engineered fungal molecules to drug leads, chem-bio hybrid synthesis enables antiparasitic drug discovery‎

Amebiasis is a parasitic disease caused by the microscopic protozoan Entamoeba histolytica. Infection occurs through the ingestion of cysts from contaminated water or food. Worldwide, approximately 50 million symptomatic cases are estimated annually, mainly in tropical and subtropical regions.

Scientists may be overestimating amounts of microplastics in the environment, and the culprit is lab gloves‎

It seems like every day a new study finds tiny plastic particles called microplastics where they should not be: in our bodies and our food, water and air.

Study finds 60% of Australia's top-use pesticides are banned in the EU‎

Analysis of Australia's highest-volume pesticide use has revealed that the majority of products widely used in Australian agriculture are banned in other parts of the world, according to a new study. Researchers from Griffith's School of Environment and Science analyzed 45 pesticide products used in volumes of more than 100 metric tons per year, identified through the Australian Government's now archived Agricultural Chemical Usage Database.

Fieldoscopy reveals femtosecond optical switching in 15 nm indium tin oxide nanocrystals‎

Just as an antenna interacts with radio waves, light interacts with metallic nanostructures. Therefore, understanding how a structure influences field oscillations provides valuable insights into the structure's physical properties. An international research team, including scientists from the Max Planck Institute for the Science of Light (MPL), is investigating the changes in field oscillations that occur when light interacts with indium tin oxide (ITO) nanocrystals. This will deepen our understanding of how the interaction between light and these nanocrystals depends on time.

Birds of prey act as sentinels to warn of forever chemicals‎

A new paper investigates how raptors, or birds of prey like hawks and eagles, act as a sentinel species that can reveal the level of forever chemicals in the local environment. The forever chemicals, or PFAS, are especially high in species that eat fish. The review titled, "Raptors as Sentinels: Unveiling the Environmental and Health Risks of Pfas Contamination," published in Toxicology Mechanisms and Methods, provides a comprehensive analysis of the current scientific data on per- and polyfluoroalkyl substances (PFAS), a persistent environmental contaminant of global concern.

How labor movements may help rebalance power in the technology sector‎

Wide swaths of American workers are more meaningfully involved than in the past in organizing around and pushing back against artificial intelligence (AI) and data-driven technologies in the workplace, a Rutgers study has found. Rutgers researchers examined the 2023 contract for the labor union Screen Actors Guild-American Federation of Television and Radio Artists (SAG-AFTRA). Their research highlights strategies for workers to use to push back through forming workers collectives around technology, developing more people-centered policies and forging solidarities with transnational labor.

NASA's Artemis II mission will take an astronaut crew around the Moon: The long road to launch‎

NASA is once again shooting for the moon, for the first time since the 1970s. As soon as April 2026, NASA will launch its Artemis II mission, using the Space Launch System heavy lift rocket to send a crewed spacecraft, called Orion, into orbit. From there, the crew will circle around the moon over 10 days.

Direct confirmation of two baby planets forming around a young, sun-like star‎

As the number of exoplanet detections has breached 6,000 and continues to grow, scientists are finding a wide variety of different solar system architectures. Critical to understanding how these architectures take shape is finding young planets forming around very young stars. In 2025, a team of astronomers announced the discovery of a planet about five times more massive than Jupiter around a star that's very much a younger version of our sun.
