Heavy metal toxicity found in Chinese port poses risk to seafood safety
Heavy metals naturally occur in the Earth’s crust, but human activities can increase their concentration in the environment, including domestic sewage and waste disposal, fumes from vehicle exhausts, fertilizer runoff, mining and fuel leaks from ships. These elements, such as arsenic, lead and mercury, can be highly toxic even in small amounts and bioaccumulate persistently, proving harmful to humans and wildlife. ⌘ Read more

Researchers observe a phase transition in a 1D chain of atoms using a quantum simulator
Phase transitions, shifts between different states of matter, are widely explored physical phenomena. So far, these transitions have primarily been studied in three-dimensional (3D) and two-dimensional (2D) systems, yet theories suggest that they could also occur in some one-dimensional (1D) systems. ⌘ Read more

Efforts to find alien life could be boosted by simple test that gets microbes moving
Finding life in outer space is one of the great endeavors of humankind. One approach is to find motile microorganisms that can move independently, an ability that is a solid hint for life. If movement is induced by a chemical and an organism moves in response, it is known as chemotaxis. ⌘ Read more
