Phys.org / Toxic evolution: How wasps and frogs mimic pain molecules to deter predators

Certain species of wasps and frogs share a pain and inflammation peptide similar to one found in vertebrates to help defend against predators—a discovery that contributes to a shifting view of how evolution works, say researchers. ...

Phys.org / Plant cell structure could hold key to cancer therapies and improved crops

Can the bend of a banana give us insight into cancer? What does the shape of a rice grain have to do with infertility? The proteins that give plants their shape and structure are also involved in human disease. A team led ...

Phys.org / Why Large Hadron Collider predictions can miss the mark, and a new way to fix it

Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it's more difficult. This is something physicists from Poland and the UK are well aware of. To improve current simulations ...

Dialog / Amazon fish contaminated with toxic metals threaten riverine communities' health

For riverside communities along the Amazon, fish is not a menu choice—it is a lifeline. Millions of people in the Brazilian Amazon depend on fish as their primary source of protein, consuming it daily in quantities far ...

Phys.org / Microbial ancestor of complex life was more sophisticated than previously thought, studies suggest

Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged all multicellular (complex) ...

Phys.org / How evolution shapes color diversity in coral reef fish

Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and patterns? A study conducted ...

Dialog / Chemically tuning nanographene into topological spin chains and why the ends matter

When most people hear "polymer," they think of plastics. In our group, polymerization is a way to line up identical molecules like beads on a string and let quantum mechanics take over. Put magnetic building blocks in a one-dimensional ...
