In each case, climate change has a different ...

Mar. 12, 2025 — Large, undisturbed forests are better for harboring biodiversity than fragmented landscapes, according to recent research. Ecologists agree that habitat loss and the fragmentation of forests reduces biodiversity in the remaining fragments. But ecologists don't agree whether it's better to focus on preserving many smaller, fragmented tracts of land or larger, continuous landscapes. The study comes ...

Mar. 12, 2025 — Challenging the long-standing belief that fibroblasts produce skin collagen, researchers have investigated collagen formation in the 'glass-skinned' amphibian axolotl and other vertebrates. They discovered that keratinocytes, the surface cells of the skin, are responsible for producing collagen, which is then transferred deeper to form the dermis. ...

Mar. 10, 2025 — Research has shown that adults instinctively think of men when asked to think of a person -- they describe the most 'typical' person they can imagine as male and assume storybook characters without a specified gender are men. A new study by psychology researchers shows that the way parents talk to their children may contribute to these ...

Mar. 10, 2025 — Researchers suggest that many metamorphic proteins have an 'underlying temperature dependence.' If confirmed, this would mean that temperature -- and cold temperature in particular -- plays a fundamental role in setting off shapeshifting in metamorphic ...

Mar. 12, 2025 — As a child, did it ever occur to you that your perception of color differed from that of others? It's quite common to have this thought, but it turns out that the human color experience may be more universal than we previously believed. In psychology and neuroscience, the relationship between subjective experience, such as how we perceive color, and physical brain activity has remained an ...
