You may know Leonardo da Vinci best for masterpieces like the “Mona Lisa” or his oft-reproduced “Vitruvian Man” drawing, but the famous artist’s interests didn’t end with art. A true Renaissance man, da Vinci studied engineering, science and just about anything that caught his eye — filling more than 7,000 notebook pages with lists and observations over the course of his life. “Leonardo was curious to know everything there was to know about everything you could know about creation, including how we fit into it,” says biographer Walter Isaacson.

In a long-ago neutron star collision, scientists find a cosmic goldmine

Nov 6, 2017

Around 130 million years ago, two neutron stars — those strange, compacted cores of dead stars — smashed into one another. The resulting “kilonova” explosion sent ripples through space-time and hurtled heavy metals like platinum and gold into space. Now, astronomers have detected the signals from that long-ago collision, in the form of gravitational waves and electromagnetic signals.

The United States’ newly revived National Space Council recently met for the first time, and in a speech before the council — tasked with setting the country’s space agenda — Vice President Mike Pence called for a return to the moon and the development of a base there.

It’s been more than 50 years since Dr. Jane Goodall first traveled to Gombe, Tanzania, as an amateur scientist and began amassing observations that would change the way we understand chimpanzees and even humans. Now a new documentary, “JANE,” reconstructs Goodall’s time in the Gombe forest, drawing on a trove of recently discovered archival footage.

We’ve all heard adults cooing to babies in “baby talk” — that high-pitched, singsong cadence we tend to slip into around infants. The overall effect of baby talk may sound unnatural, but as Princeton neuroscientist Elise Piazza explains, the exaggerated high pitch, repetition, rhythm and even the pauses in baby talk can give babies important acoustical information about how language works.
