Hints emerge of a four-quark particle
Previously observed only in twos, threes, and perhaps in fives, quarks and antiquarks in a newfound particle may have glommed together to form a never-before-seen foursome.

Discovery of Insulin
In 1923, the Nobel Prize in Medicine went to Frederick Banting and J.J.R. Macleod for their part in the discovery of insulin. This site documents that discovery and the initial development of insulin to alleviate suffering from diabetes. Part of the University of Toronto Libraries’ digital collection, the site features more than 7,000 images, reproducing […]

This article speculated on the evolutionary origins of thermogenesis and observed how it predominates in ancient lineages of flowering plants like magnolias and water lilies. But thermogenesis goes back much farther than this, for it also occurs in cycads, nonflowering plants that arose in the Paleozoic. The male cones of some cycads, when mature, may […]

This article describes attempts to use ketones as a substitute for glucose when it’s unavailable to the brain because converted fats can’t penetrate the brain. Wouldn’t it be simpler to feed or inject glucose directly? Oliver H. WinnCorona del Mar, Calif. The researchers who conducted the study say that giving glucose might help in some […]

Doppler Toppler: Experiment upends normal frequency shift
The expected drop in frequency of a signal from a receding source—the Doppler effect—becomes a frequency increase when a high-current electric pulse creates extraordinary electromagnetic conditions in a web of electrical components.
