Touching thermal-paper receipts could extend BPA retention in the body

When people handle receipts printed on thermal paper containing the endocrine disruptor bisphenol A (BPA), the toxic chemical could linger in the body for a week or more. Jonathan W. Martin of Stockholm University and Jiaying Liu of the University of Alberta asked six male volunteers to handle paper containing isotopically labeled BPA for five minutes. The volunteers then put on nitrile gloves, wore them for two hours, removed them, and washed their hands with soap. Afterward, the researchers measured the labeled BPA and its metabolites in the volunteers’ urine regularly for two days and then once again a week later. The study only traced the isotopically labeled (deuterated) BPA and its metabolites, so any additional BPA exposure from other sources was not monitored.

Largest prime number discovered: with more than 23m digits
Known simply as M77232917, the figure is arrived at by calculating two to the power of 77,232,917 and subtracting one, leaving a gargantuan string of 23,249,425 digits. The result is nearly one million digits longer than the previous record holder discovered in January 2016. The number belongs to a rare group of so-called Mersenne prime numbers, named after the 17th century French monk Marin Mersenne. Like any prime number, a Mersenne prime is divisible only by itself and one, but is derived by multiplying twos together over and over before taking away one. The previous record-holding number was the 49th Mersenne prime ever found, making the new one the 50th.

We raise girls to cater to the fragile egos of men. We teach girls do shrink themselves, to make themselves smaller. We tell girls ‘You can have ambition, but not too much’. ‘You should aim to be successful, but not too successful, otherwise you will threaten the man’. (…) We teach girls shame – ‘Close your legs, cover yourself!’. We make them feel as though by being born female, they’re already guilty of something. And so, girls grow up to be women who cannot see they have desire. They grow up to be women who silence themselves. They grow up to be women who cannot say what they truly think. And they grow up – and this is the worst thing we do to girls – to be women who turn pretense into an art form.
