\nToday is American pi day. Using the American convention of representing today's date as 03.14.07, it's easy to see why mathematicians are so excited about today's date, which very much resembles a quick approximation of the value of pi, or 3.14159. (One can only imagine the lack of decorum that must have prevailed back in 1915, when the date was a perfect 03.14.15). Yahoo! News has the details:
"[This is a story] about a curious group of people with an almost religious zeal for a\nmind-numbing string of numbers. Actually one number, made up of a chain\nthat is known — so far — to be more than one trillion digits long. They\nare the acolytes of the church of pi.\n\n
And once a year many of them gather to talk about pi, rhapsodize\nabout it, eat pi-themed foods (actual pie, sure, but so much more),\nhave pi recitation contests and, just maybe, feel a little less\nsheepish about their unusual passion.\n\n
That day falls on Wednesday this year: March 14. Or 3.14. Obviously."

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
