Gravity from positivity: Single massive spin-3/2 particle makes gravity logically inevitable, study claims‎

Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles are enough: causality, the fact that no signal can travel faster than light, and unitarity, the requirement that probabilities are conserved in quantum mechanics. The structure of supergravity is not assumed: it bootstraps itself.

How can science support and enable the High Seas Treaty?‎

The Biodiversity Beyond National Jurisdiction (BBNJ) agreement—often known as the High Seas Treaty—came into force in January 2026 following almost two decades of negotiations. Its key objectives are the conservation and sustainable use of marine biological diversity in areas that lie outside any single country's jurisdiction, remote areas that make up roughly two-thirds of the global ocean—areas that remain largely unexplored but hold as yet unquantified levels of valuable biodiversity and resources.

Underground lab clears crucial hurdle for dark matter hunt‎

Australia's bid to detect elusive dark matter has taken a major step forward, with new research confirming that cosmic radiation levels deep inside the Stawell Underground Physics Laboratory (SUPL) are low enough to support the world-class experiment that will commence later this year.

DNA-binding protein blocks virulence cascade in a diarrhea pathogen outside hosts, study finds‎

Some pathogens use temperature as a trigger and activate virulence only after entering the warmer environment of a host. A research team from Ruhr University Bochum, Germany, and the University of Münster, Germany, investigated how a diarrheal pathogen suppresses its virulence outside of the human body. Their study focused on the DNA-binding protein Fis, which is more abundant at cooler ambient temperatures of about 25°C.

Ocean Discovery League launches global strategy to double deep seafloor observations‎

Ocean Discovery League (ODL) has launched the Global Deep Sea Exploration Goals, an ambitious international effort to visually explore 10,000 strategically selected locations across the deep seafloor. When completed, this initiative will nearly double the number of unique seafloor locations ever visually observed and produce the first globally representative visual dataset of the deep ocean floor.

Software package makes gene regulation easier to study—and tweak‎

Understanding how genes are switched on and off in specific cell types remains one of biology's central challenges. While AI has made major progress in decoding the regulatory logic of DNA, applying these approaches across datasets, tissues, and species has remained difficult. In a new study published in Nature Methods, a research team led by Prof. Stein Aerts (VIB & KU Leuven) presents CREsted, a software package that enables both the analysis and design of gene regulatory elements in a systematic and scalable way.

Wildfires accelerate winter snowmelt in Oregon's western Cascades, study finds‎

The Pacific Northwest has seen below-normal snow this season—and new research from Portland State University suggests that the region's snowmelt-dependent water resources could face growing challenges in the years ahead as forest fires and winter rainstorms become more frequent.

AI turns electron microscopy into materials insights in minutes‎

An electron microscopy image can capture atoms arranged in a crystal lattice or defects threading through a semiconductor material, but turning that image into materials insight can take weeks of careful analysis. Now, an autonomous artificial intelligence platform developed at Cornell can do that work in minutes.

Watering smarter, not more: A modern-day robotic divining rod‎

Advanced technology can help farmers get to the root of a growing problem—overwatering in an era of increasing drought and water scarcity. A new UC Riverside system can map soil moisture tree by tree, so growers water only where and when it's needed.

World's oldest tortoise very much alive despite death rumors‎

Reports of the death of the world's oldest living land animal—a nearly 200-year-old tortoise—were greatly exaggerated.
