Tropical rainforest birds are disappearing even in undisturbed forests – researchers fear a new “silent spring”
Long-term monitoring data in Brazil, Panama and Ecuador indicate a sharp decline in birds, especially insectivorous species, and it is possible that the climate crisis and the decline in insect numbers are destabilizing tropical forest ecosystems.

Between flood and drought: The metric that can better explain what's happening to water in the era of climate change
Climatic tipping points are critical thresholds in Earth's systems – such as the oceans, ice sheets and forests – where warming can push the climate to a new state. Once the threshold is crossed, the changes are difficult to reverse and can set off a chain reaction that affects ecosystems, extreme weather events and the global climate. Credit: ESA

Computing and technology

The subtle scent left behind by ancient Egyptian mummies may hold much more information than previously thought. By analyzing volatile chemical compounds emitted into the air from mummified remains, researchers have been able to uncover new details about how embalming methods evolved over more than two millennia.

Society and history

A historian has discovered that a 16th-century printed edition of the Almagest — an ancient and influential astronomical treatise — includes numerous handwritten footnotes by Galileo Galilei, the astronomer who later challenged the geocentric view of the universe presented in that treatise.

A copy of Ptolemy's Almagest with notes in Galileo's handwriting was discovered in Florence.
