Millions of vultures vanished after a cattle drug, followed by 500,000 human deaths
For generations, vultures were part of the everyday landscape, clearing livestock carcasses before they could linger. In the 1990s, diclofenac caused their numbers to collapse from around 50 million. Their disappearance was linked to rising stray dog numbers, water contamination and an estimated 500,000 additional human deaths between 2000 and 2005.
Three African wild dog brothers travelled 4,126 km; the longest recorded African mammal dispersal
A trio of African wild dog brothers undertook a remarkable odyssey covering 4,126 kilometers across Zambia. This unprecedented trek marks the longest documented dispersal by a mammal in Africa. Their journey through various terrains, including natural reserves and areas impacted by humans, highlights the crucial need for habitat connectivity beyond national park borders, revealing pressing conservation issues faced by species that require large ranges.
In 1986, captive-bred bearded vultures returned to the Alps; by 2021, 344 lived there wild-born
Bearded vultures have returned to the Alps after decades of absence. A reintroduction program successfully established a self-sustaining population by 2021. Wild-hatched birds increasingly drove this population growth and recovery. However, recovery has been uneven across the Alpine range. Ongoing threats and survival differences still shape the species' future.
Colorado buys 2,100-acre ranch to help save lesser prairie-chickens from decline
Colorado’s lesser prairie-chicken population has fallen from more than 80,000 birds in 1975 to only 89 breeding males in 2024. The Southern Plains Land Trust has acquired nearly 2,100 acres for just under $2 million to restore grassland habitat. The property, near an active breeding site, will be restored with Colorado Parks and Wildlife to support the species’ recovery.
In 2013, St Agnes and Gugh began rat eradication; 12 yrs later, Manx shearwater sites hit record 225
A rat eradication project on St Agnes and Gugh in the Isles of Scilly began in 2013 after invasive brown rats were found to be threatening nesting seabirds. The islands have remained rat-free since the operation, while Manx shearwater breeding numbers have increased from 22 pairs before eradication to 225 apparently occupied breeding sites recorded in 2025.
Former Australian miner spotted Saturn ripple in 2024; two years later, co-authored 10-sided wave
An Australian amateur astronomer made a groundbreaking observation in their backyard, discovering a colossal ten-sided atmospheric wave. This unique finding corroborated the existence of a decagon around Saturn's south pole, as confirmed by years of data from the Hubble Space Telescope. The decagon, intertwined with fierce jet streams, spans numerous atmospheric levels, shedding light on the circulatory processes within the atmospheres of these gas giants.
Britain’s butterfly boom comes with a warning for next year
Britain experienced a significant butterfly boom during the record heat of summer 2026. Over 100,000 volunteers counted nearly 1.4 million butterflies and moths across the nation. Painted ladies, a migratory species, saw their numbers surge by 335 percent this season. Experts warn this boom could lead to a population crash for caterpillars next year. Drought conditions that benefited adult butterflies harmed their offspring and food sources.
Greenland, Antarctica have lost 11,309 billion tonnes of ice since 1979, raising sea levels by 31.4 mm
Greenland and Antarctica have lost 11,309 billion tonnes of ice since 1979, raising global sea levels by 31.4 millimetres, a new assessment finds. Faster-flowing glaciers accounted for 84% of the loss, while surface melting contributed 16%. Scientists say the findings highlight the long-term impact of warming oceans on polar ice sheets.
Cow Creek Wildfire: Florida forest rebounds with flowers and pollinators; shows fire-shaped ecology
After a recent wildfire, Florida's Goethe State Forest has experienced a vibrant resurgence of wildflowers and grasses. These native plants, adapted to thrive post-fire, regrow vigorously from their roots. This rejuvenation not only revives the landscape but also offers new food and nesting opportunities for returning insects, highlighting a powerful, enduring cycle of fire-induced renewal in Florida’s rich ecosystem.
Large Blue Comeback: extinct UK butterfly surges 1,866%; ecosystem fix drives recovery
After being declared extinct in Britain, the large blue butterfly has made a remarkable return, flourishing across thirty-three different sites. Since 1983, its population has soared by an astounding 1,866%. This resurgence showcases a delicate ecological interplay with specific food plants and ants. Thanks to focused conservation efforts in habitat restoration and understanding its life cycle, the large blue stands as a powerful symbol of successful species recovery.
Japan village turns 40,000 tonnes of discarded scallop shells into stronger safety helmets
In Sarufutsu village, the burgeoning problem of scallop shell waste has taken center stage. A plastic manufacturing firm has crafted a groundbreaking material known as Shellstic using these shells. This eco-conscious innovation leads to the creation of Shellmet - an exceptionally durable helmet for fishermen, outperforming standard plastic versions. Such developments offer a promising approach to resolving industrial waste concerns sustainably.
