Identical twins are on trial. Can DNA testing tell them apart? In a French criminal trial, conventional DNA analysis couldn’t distinguish between twin brothers, but emerging scientific methods could help in such cases

An excerpt of an article about pie-making machines from the September 30, 1905 issue of Scientific American A photo printed in the September 30, 1905 issue of Scientific American that shows 3 people using a pie-making machine An excerpt from the pie-making machine article from the September 30, 1905 issue of Scientific American.

In 1905, Scientific American dismissed the pie-making machine because the pies were “too perfect.” 🥧

This Pi Day, we’ll concede they may have been a little…irrational about pie machines, but never about the mathematical constant π. #PiDay

Winter is back for those of us in the Northeast, who are probably getting pretty sick of the cold at this point. But here's the thing--it wasn't actually that cold, historically speaking. And uh, sorry to the folks out West 🧪

I had a lot of fun working on this piece for @sciam.bsky.social about the wacky places that pi arises in random values. And as always, so grateful to @unamandita.bsky.social for her gorgeous graphics.
