The Overpopulation Debate
2010 was the year good old-fashioned, blame-it-on-the-breeding-masses overpopulation theory re-entered the mainstream. There’s just too many Malthusians, says Tim Black.
In 2008, we had the hyper-intelligent, hyper-unreadable Stephen Hawking telling us there would literally be no room on the planet by 2600. And then of course, in April 2009, Sir David Attenborough came out as an adversary of procreation and promptly joined the Optimum Population Trust. "I’ve never seen a problem", he announced, "that wouldn’t be easier to solve with fewer people, or harder, and ultimately impossible, with more".

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.

- 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.
