For decades, we were told to choose low-fat dairy. New research says otherwise

A new Canadian study led by University of Toronto professor Harvey Anderson adds to growing evidence that full-fat dairy can be part of a healthy diet. In the 12-week study, 74 adults consumed different amounts of dairy under varying dietary conditions. The researchers found that eating three servings of full-fat…

Scientists discover bacteria that lock toxic uranium into a stable form

Uranium, a radioactive heavy metal, is typically locked inside minerals in soil. However, mining and other environmental processes can change uranium into forms that dissolve in water. Once it becomes mobile in this way, it can spread through the environment and create problems because of its toxicity. Researchers at the…

Chemists set electrons free and break a decades-old chemistry barrier

Chemists depend on sophisticated molecules to develop life-saving drugs, produce advanced high-tech materials, and recreate processes found in living systems. One of the most useful tools for building these complicated structures is single-electron transfer, a technique that can activate molecules that would otherwise resist reacting and allow them to join…

Dinosaurs became giants — so why did they never become tiny?

Dinosaurs are often remembered for their enormous size. Tyrannosaurus rex was an imposing predator, while dinosaurs such as Apatosaurus reached truly massive proportions. Yet new research suggests that one of the most intriguing questions about dinosaur evolution lies at the opposite end of the size spectrum: Why did dinosaurs apparently…

Wine, beer, or spirits? Massive study finds a surprising health divide

Heavy alcohol use has consistently been tied to poorer health, no matter what type of alcohol a person drinks. At lower levels of consumption, however, the health effects may differ depending on the beverage, according to research presented at the American College of Cardiology’s Annual Scientific Session (ACC.26). The findings,…
