Caribbean Islands Reveal a “Lost Word” of Ancient Mammals

Although filled with tropical life today, the Caribbean islands have been a hotspot of mammal extinction since the end of the last glaciation, some 12,000 years ago. Since people also arrived after...

Synthetic Material Acts like an Insect Cloaking Device

Synthetic microspheres with nanoscale holes can absorb light from all directions across a wide range of frequencies, making them a candidate for antireflective coatings,...

Noise Pollution Found to Be Disruptive for Schooling Fish

Human activities, like spreading cities, transport and construction, generate a lot of noise that travels faster in water than in air. But cohesion and coordination...

Eyes That Lie: Protective Deception of Eyespots Confirmed

New evidence published recently in The American Naturalistshows that prey eyespots intimidate predators because they associate the eyelike appearance of eyespots with the threat...

Size Matters in Battle Against Extinction, Scientists Find

Researchers have found the Goldilocks zone for animals lies in being mid-sized, with apex predators over-hunted and small vertebrates like pollinators threatened by habitat...
