Scientists have identified traces of original collagen in an Edmontosaurus fossil from South Dakota. The finding, published in 2025, challenges the belief that all biological material is lost during fossilization.

New technologies are allowing researchers to peer into the nanoscale workings of the human immune system. Immunologist Daniel Davis highlighted these advances at WIRED Health. The insights could transform approaches to diseases like cancer.

Researchers at the University of Queensland have discovered that many scorpion species strengthen their claws and stingers using blends of iron, zinc, and manganese. The metals concentrate in the tips and cutting edges, making these weapons tougher, similar to a steel-capped boot. The findings come from examining 18 species worldwide.

Researchers led by Dr. Alireza Zamani of the University of Turku have identified four previously unknown tarantula species in the Arabian Peninsula and the Horn of Africa. These spiders are so distinct that they required a new genus, Satyrex, named after a mythological figure and Latin for king. Males feature the longest palps recorded in tarantulas, possibly to safely mate with aggressive females.

Researchers at the University of York have identified a protein called ESB2 that acts as a molecular shredder, enabling the African trypanosome parasite to evade the human immune system. The parasite, which causes sleeping sickness, uses ESB2 to precisely edit its genetic instructions in real time. This breakthrough solves a 40-year mystery in the parasite's biology.
