While many Internet users may understand that algorithms affect their social media feeds, few realize that algorithms also personalize their online shopping experiences. Researcher ...read more
Dendrochronologist Henri Grissino-Mayer and colleagues study the tree rings in the Karr-Koussevitzky double bass. Their analysis ultimately determined that the instrument was built much later than previously thought. (Credit: Henri Grissino-Mayer)
Modern science is full of surprising analytical techniques that can be used in a wide variety of remarkable circumstances.
My favorite technique is dendrochronology—the study of “tree time.” By assigning calendar-year dates to growt ...read more

It’s a familiar scene that played out most recently at the London marathon: An exhausted runner staggers and falls in the home stretch, unable to will their legs forward another step. It’s an extreme example of a phenomenon endurance athletes come to know intimately, often called “hitting the wall,” or sometimes by the more offbeat term “bonking.”
The proverbial wall appears when our bodies have run out of store ...read more

The first draft tea tree genome is revealing how the world’s most popular beverage developed its unique flavors and soothing properties.
Despite the wide variety of teas that adorn store shelves today, there is just one species of plant that produces tea leaves. Two varieties of Camellia sinensis, a type of evergreen shrub, are responsible for everything from Masala chai to oolong teas, with small variations in the way the leaves ar ...read more
