AI makes rewilding look tame—and misses its messy reality
Humans have always imagined the natural world. From Ice Age cave paintings to the modern day, we depict the animals and landscapes we value—and ignore those we don't.

Insects in the tropics are already near their heat limits. Climate change could push many beyond survival
Insects make up to 90% of all animal species on the planet, and most of them can be found in the tropics, the regions around the equator. Yet we still know surprisingly little about how these species will cope with rising temperatures driven by climate change.

Two's company: Scientists identify new class of star remnants
In about 5 to 8 billion years, our sun is expected to evolve into a white dwarf—an extremely dense, Earth-sized stellar remnant that has exhausted its fuel and shed its outer layer. But while our sun is a solitary star, research over the past 15 years has demonstrated that binary or multi-star systems are far more common than astronomers once thought. When a dense and compact remnant like a white dwarf is involved in a binary system, it often "snatches away" material from its companion star. This process, called accretion, usually emits X-rays in what is considered a "signature" signal.

Thermal justice: New report examines threat of extreme heat, suggests culturally informed policies
Extreme heat kills more people in the U.S. each year than hurricanes, floods, and tornadoes combined. But how can we address a seemingly natural force? Heat can often seem solely weather-related, with policies trying to find a solution through temperature metrics, cooling technologies, and alerts. However, a new report from the Vanderbilt Cultural Contexts of Health and Wellbeing Initiative (VU-CCH) suggests that extreme heat is not just a climate issue, but also a social one.

Humans' closest invertebrate ancestors date back much further than thought
Animal life is extraordinarily diverse and complex, having colonized almost all environments on Earth—from hostile hydrothermal vents in the deep sea to the skies across our continents. But the planet was not always teeming with complex animal life. For the first 3.7 billion years after it originated, life was small, simple and largely confined to the oceans. This microbe-dominated world was a tumultuous place, with several major swings in its climate.

A simple ECG test could flag racehorses at risk of exercise arrhythmias
A quick heart trace taken during a warm-up trot could identify racehorses at risk of cardiac arrhythmias during high-intensity exercise, according to a new study led by the University of Surrey. The screening method analyzes short, routine electrocardiogram (ECG) recordings that could be used to help prevent cardiac events in otherwise healthy horses, where no obvious signs of arrhythmia have been detected.

How we came to be: Scientists get first look at the evolution of early complex animals
Newly discovered fossils have given scientists their first real glimpse of when Earth made a crucial transition from plants and unrecognizably simple animals to the complex creatures that took over the world and would eventually lead to us.
