1 in 4 Statisticians Say They Were Asked to Commit Scientific Fraud
As the saying goes, "There are three kinds of lies: lies, damned lies, and statistics." We know that's true because statisticians themselves just said so. A jaw-dropping study reveals that nearly 1 in 4 of them report being asked to remove or alter data to better support a hypothesis. That is called scientific fraud.

It’s raining PFAS: rainwater is unsafe to drink even in Antarctica and Tibet
Per- and polyfluoroalkyl substances (PFAS) are man-made hazardous chemicals that are spread globally in the atmosphere and as a result they can be found in the rainwater and snow in even the most remote locations on Earth. During the last 20 years, guideline values for PFAS in drinking water, surface waters and soils…

The baffling intelligence of a single cell: The story of E. coli chemotaxis
I want to tell the story of a beautiful phenomenon in biology. In some sense it’s the prototype of much of the activity of life. The phenomenon is the way in which an individual cell of E. coli forages for nutrients. This process, known as “chemotaxis”—the “chemo-” for chemical and the “taxis” from the Greek τάξις…
