- Study reveals there is a general mechanism deep in the human brain that alerts us almost instantaneously when we make an error. The neurons involved in this, retain specific details related to the event, making it possible for the brain to access that information, and quickly correct the mistake https://www.caltech.edu/about/news/to-err-is-human 45 comments science

- In 1965, 4 years before the Moon landing, the Mariner 4 Mars flyby crushed fantasies but began Mars exploration. Many hoped for pictures of life on Mars. Mariner 4 revealed a desert covered with craters much like the Moon. The photos captured a curious world’s attention, and showed we are alone. https://www.caltech.edu/about/news/alone-darkness-mariner-4-mars-50-years-later-47324 350 comments space

- Hidden donors (those who donate less than $200) play a significant role in political campaigns, new study shows. Small donations made up 33% of total funds for Bernie Sanders’ presidential campaign in 2016. The hidden donors tended to be students, females and racial/ethnic minorities. https://www.caltech.edu/about/news/hidden-donors-play-significant-role-political-campaigns 92 comments science

- Choice overload happens when the brain, faced with an overwhelming number of similar options, struggles to make a decision. A new Caltech study reveals the parts of the brain responsible for it, and how many options the brain actually prefers when it is making a choice - somewhere between 8 and 15. http://www.caltech.edu/news/scientists-uncover-why-you-cant-decide-what-order-lunch-83881 175 comments science
