Researchers from Sloan and the Media Lab examined why false news spreads on Twitter more quickly than factual information. “Twitter bots amplified true stories as much as they amplified false ones,” writes Robinson Meyer for The Atlantic. “Fake news prospers, the authors write, ‘because humans, not robots, are more likely to spread it.’”

Prof. Linda Griffith has developed ten miniature models of human organs “to create the closest we’ve come yet to a human-on-a-chip,” writes Jessica Hamzelou for New Scientist. “This is still only a minimal representation of a human,” said Griffith, but this kind of system could eventually eliminate the need for animal testing.

A study led by graduate student Hilary Richardson provides evidence that by age 3, children “have begun developing brain networks used to understand the beliefs and feelings of others,” writes Laney Ruckstuhl for The Boston Globe. “Richardson said researchers previously believed the networks used in theory of mind reasoning were not developed until at least age 4,” explains Ruckstuhl.

New research from visiting scientist Judah Cohen suggests that “severe winter weather in the United States is often tied to (relatively) high heat in the North Pole,” writes Eleanor Cummins for Popular Science. “If the Arctic is cold, that favors less severe winter in the eastern U.S.,”said Cohen. “When the Arctic is warm, it’s the opposite relationship.”
