Scientists stunned as JWST finds ice clouds on a giant alien planet
Astronomers using the James Webb Space Telescope have detected water-ice clouds on Epsilon Indi Ab, a Jupiter-like exoplanet roughly 12 light-years away — a discovery that defied existing predictions. The clouds appear to be suppressing ammonia levels in the atmosphere, upending models scientists had relied on to understand giant planet chemistry. The finding underscores how little we know about the atmospheric dynamics of worlds beyond our solar system.

Global appetite for beef is driving Amazon deforestation, new study finds
Global demand for beef is fueling Amazon deforestation at scale, with a new international study directly linking consumer purchasing habits to land clearing in Brazil. The research exposes how sprawling, opaque supply chains make it easy for responsibility to be diffused across borders, undermining existing regulatory efforts. The findings suggest that without tackling demand at the consumer level, deforestation policies targeting producers alone will continue to fall short.

Discovery of new polymer class provides compostable alternative to conventional thermoplastics
Researchers at the University of Bayreuth have identified a new class of polymers that are fully biodegradable, recyclable, and more sustainably processed than conventional thermoplastics. The breakthrough, published in the journal *Small*, offers a promising material alternative at a time when microplastic pollution continues to strain ecosystems globally. If scalable, this discovery could reshape how industries approach plastic production and end-of-life disposal.

Cities and countries warming fast, new climate stripes show
Global temperatures are rising at a striking pace, and newly updated climate stripes make that reality impossible to ignore. The graphics, released for Earth Day, now incorporate 2025 data and map warming trends across individual cities and countries worldwide. The visual tool puts a sharp, local face on a global crisis, showing residents exactly how dramatically their own region has changed.

Two common drugs may reverse fatty liver disease, study finds
Researchers have found that combining two existing drugs can dramatically reduce liver fat associated with fatty liver disease, with lower combined doses proving as effective as higher individual doses. The treatment also showed potential cardiovascular benefits in animal models, raising hopes for a dual-purpose therapy. The findings represent a significant step forward for a condition that affects millions yet often goes undetected until serious damage occurs.
