The Perfect Burger? Try Liquid Nitrogen.
Any food is worthy of trying to achieve the ultimate version of it. Our version of the ultimate burger is a little tough to do at home because it involves liquid nitrogen and a deep fryer. We grind the hamburger, we put it in liquid nitrogen, and then we deep fry it to make a crispy crust after we cooked it sous-vide to make the inside even.
I think the real trick with making a great burger is to make sure you use a hot enough either flame or pan or barbecue to get the outside really crusty while keeping the inside medium rare. And that's easiest to do if you can cook the burgers very gently first at low temperature to get the inside medium rare, then briefly sear the hell out of it to make the outside crispy.
Nathan Myhrvold describes techniques for cooking the perfect burger, including dousing the patty in liquid nitrogen.

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.

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.
