Online and undercover: Saving trafficked wildlife in Thailand‎

Nawee Changpirom has spent years working to rescue trafficked wildlife in Thailand, but even he can sometimes hardly believe the creatures he has found: leopards, hornbills and, once, an anteater.

Coyote density is 9 times higher in Seattle than in Washington's wildlands‎

Once coyotes get a taste for city living, the call of the wild fades to a whisper. Food is abundant and predators are few. Research indicates that coyotes enjoy the benefits of urban areas enough to put up with all the people, and Seattle is no exception.

Global heat stuck on high. Scientists say August was Earth's hottest month they've measured.‎

Earth cooked to its hottest month on record in August, blowing far past a key climate threshold, due to the dangerous double whammy of human-caused climate change and a supersized El Niño, according to the European climate service Copernicus.

Anthropic researcher resigns with warning about the dangers of AI development‎

An Anthropic researcher said he is resigning from the company over concerns the artificial intelligence firm and its competitors are not acting responsibly in AI development, echoing concerns raised inside and outside of the industry about the technology's potential to elude human control.

A stronger-than-normal El Nino alarms scientists over Galápagos wildlife and forests‎

The prediction that this season's El Niño phenomenon will be stronger than normal has alarmed the Ecuadorian scientific community, which has warned of its impact on the flora and fauna of the Galapagos Islands, home to the highest concentration of species not found elsewhere on Earth.

Timing 1080 drops to prevent predators bouncing back‎

While aerial 1080 drops sharply reduce numbers of rats and stoats, the predators—especially ship rats—can rebound to higher numbers within a few years. Studying 24 years of small-mammal tracking records across New Zealand's public conservation land, researchers found that the timing of these rebounds varies between regions.

Can AI tame torrential rain by 2050? The next frontier of weather control and forecasting‎

Japan has been experiencing increasingly severe damage from torrential rainfall triggered by typhoons and stationary linear rain bands. In response, an ambitious and unconventional idea is taking shape: artificially inducing heavy rainfall over the ocean to reduce extreme downpours on land.

AI and big data can help logistics companies navigate supply-chain disruptions‎

Artificial intelligence and big-data capacity might help logistics companies withstand supply-chain disruptions by making them more agile and resilient, according to research in the International Journal of Business Performance and Supply Chain Modelling. The results are based on an analysis of responses from almost 300 logistics professionals in Indonesia.

Four in five researchers report harmful interactions during geoscience fieldwork. A new survey suggests a path forward.‎

Fieldwork is a vital part of geoscience research, allowing scientists and students to directly observe, interact with and collect data about Earth processes that cannot be replicated in the lab.

X-ray photoelectron spectroscopy reveals the surface chemistry of bio-based hybrid materials‎

Just a few atomic layers at the surface can strongly influence how effectively a material binds pollutants from water or how efficiently a photocatalyst responds to light. Researchers at the Fraunhofer Institute for Applied Polymer Research IAP use X-ray photoelectron spectroscopy (XPS) to investigate the chemical states and interactions at the surfaces and interfaces of bio-based carbon materials and organic-inorganic hybrid materials. Their insights can support the targeted development of functional materials for future industrial applications.
