Drone footage revealed constant violations of Mexico’s whale shark tourism rules, even when far fewer boats were on the water than regulations allow. The findings raise broader questions about whether popular wildlife encounters — from manta rays and sea turtles to whales and even elephants — are truly “ecotourism” and highlight the need for stronger monitoring and community-led stewardship.

Kyushu University researchers have created a novel “ACTG” naming system for human gene types, and launched the Joint Open Genome and Omics Platform 1.0 (JoGo 1.0), a global database cataloging 4.7 million gene types from more than 19,000 genes. Integrated with other public resources, the platform establishes a universal language for human gene types, empowering applications in fields such as disease research, drug development, and evolutionary biology.

A research team led by Prof. ZHU Min—member of the Chinese Academy of Sciences (CAS) and affiliated with the CAS Institute of Vertebrate Paleontology and Paleoanthropology (IVPP)—has identified a new species of fossil lungfish from Early Devonian deposits in Zhaotong, Yunnan Province. The findings, published recently in the journal Current Biology, help fill a long-standing gap in scientists' understanding of lungfishes' early evolutionary history.

Metabolic dysfunction-associated steatotic liver disease (MASLD), a spectrum of liver conditions ranging from simple steatosis to steatohepatitis (MASH), fibrosis, and cirrhosis, represents a global health epidemic with no approved pharmacotherapies.

 

The liver plays a central role in maintaining systemic energy homeostasis during fasting by mobilizing lipid reserves, a process often accompanied by transient hepatic steatosis. Dimethylarginine dimethylaminohydrolase 1 (DDAH1), a key enzyme metabolizing asymmetric dimethylarginine (ADMA), has been shown to protect against NAFLD under nutrient-overload conditions. However, its role in the physiological context of fasting remained elusive.

Why do some children develop a brain that is too small (microcephaly)? An international research team involving the German Primate Center – Leibniz Institute for Primate Research (DPZ), Hannover Medical School (MHH), and the Max Planck Institute of Molecular Cell Biology and Genetics has used human brain organoids to investigate how changes in important structural proteins in the cell lead to this severe developmental disorder (EMBO Reports).

Today, the Arabian Gulf is home to manatee-like marine mammals called dugongs that shape the seafloor as they graze on seagrasses. A newly described fossil site in Qatar reveals that ancient sea cows engineered aquatic ecosystems in a similar way more than 20 million years ago.

By testing for microbes in termite excrement, researchers can distinguish old droppings from fresh, and whether a colony is actively chewing its way through a home.
