A net to protect against the world's deadliest animal—the mosquito

When people talk about the world's deadliest animal, many think of sharks, alligators or lions. But in reality, it is a small, unassuming—yet all the more annoying—insect: the mosquito. Worldwide, more than 700,000 people die each year from diseases transmitted by mosquito bites. The shark, by contrast, is responsible for only 10 human deaths per year.

Global fossil fuel emissions set to fall in 2026, but total CO2 keeps rising

Global fossil fuel emissions are projected to fall in 2026 as renewable energy and electric vehicles gain ground, but rising emissions from deforestation threaten to push total CO2 emissions to a new record. Scientists warn that the world's remaining carbon budget for limiting warming to 1.5°C could be exhausted in less than four years, even as a lasting decline in emissions appears increasingly within reach.

Tree-rich landscapes help birds and bats nearly double cacao yields in Peru

Tropical farmers are often expected to choose between high crop yields and protecting wildlife. However, an international team of researchers led by the University of Vienna, in collaboration with the universities of Göttingen and Würzburg in Germany and Bioversity International in Peru, shows that biodiversity conservation reinforces cacao production in agroforests via associated ecosystem services, such as natural pest control. The new study, published in Communications Earth & Environment, provides important evidence for sustainable farm and landscape management in one of the world's most biodiverse regions.

Some regions may already be living in a 1.5°C warmer world

Regions worldwide may have already experienced around 90%–94% of the warming expected when the global average reaches 1.5°C above preindustrial levels, and 65%–76% of that expected at 2°C of warming. The findings, published in Nature Climate Change, suggest that regional warming in 2025 was statistically indistinguishable from the levels expected in a 1.5°C warmer world, underlining the immediate need for adaptation across all regions.

Not a 'night owl' yet: Extraordinary bird fossil from Messel Pit suggests species still hunted by day

An exceptionally well-preserved, approximately 47-million-year-old owl fossil from the UNESCO World Heritage Site Messel provides new clues as to when owls became nocturnal. The newly described species Masillastrix blattophaga was likely still diurnal—as indicated by an iridescent cockroach in its stomach, as well as the structure of its feathers and wing bones. In their new study, published in the journal Current Biology, the Senckenberg researchers speculate that nocturnal behavior in owls only developed between the middle and late Eocene, some 47 to 34 million years ago.

The hidden ways insects support animal life—from habitat to health—go way beyond being food

There are at least 14 million insect species on Earth, and they play highly diverse roles in sustaining the natural world. Insects provide many well-known benefits—what scientists often call "ecosystem services." For example, you can thank a bee or a hoverfly for pollinating wildflowers and agricultural crops, or credit dung beetles for decomposing manure and other waste materials.

Thunderstruck: what does the future hold for lightning?

Humans have always been awed by the power and beauty of lightning. How does the experience and understanding of it change in a warming world? In a rock shelter in Kakadu national park in the north of Australia is an image of a being the Bininj people call Namarrkon . His flesh bleached away to reveal the bones beneath, he wears stone axes on his head, elbows and knees, and wields a great band of lightning that runs from his ankles up, over his head. Namarrkon’s journey from the Arafura Sea to the Arnhem Land escarpment helped shape the landscape, according to the dreamtime stories of the Bininj. And in the great storms that arc and rumble across the landscape during the buildup and the wet season, it is Namarrkon who splits the clouds with his stone axes to create the thunder and lightning and release the life-giving rain.

New method measures microplastics in the air using an uncrewed aerial system

Microplastics have been found in our bodies and the food we eat—and even in remote environments around the world, including seawater and ice in the Arctic. Despite their prevalence, little is known about how they move through the atmosphere. New CIRES-led research, which demonstrates a new method for sampling microplastics in the atmosphere using an uncrewed aerial system (UAS), aims to change that. The findings are published in the journal Scientific Reports.

High-precision timeline helps clarify an ancient magma surge in the North Cascades

Where oceanic crust subducts beneath continental crust, belts of volcanoes known as continental arcs can form. Located around the world, these arcs may undergo episodic magma flare-ups—dramatic surges in the flow of magma into the continental crust at rates up to 20 times higher than normal. However, what triggers these extreme surges, which last tens of millions of years, can be unclear.
