Question #1: Beef and Climate Change ()
You have talked about the destruction of habitats and how biodiversity is going down because of this. Isn't one of the biggest contributors the demand for meat, and especially beef, because many acres of rain forest get burned down to plant soy and corn to feed livestock? Wouldn't phasing out meat consumption be the "low-hanging fruit" regarding biodiversity and climate change? I think grass-fed cattle is carbon neutral, but what percentage of all the beef consumed is that? We can talk a lot about the missing political will to change things or about greedy corporations, but in my opinion it has to start with the consumer.

Theme: Magnetism
Item #1: Scientists have defied a 178 year old theory by developing a technology for remotely canceling magnetic fields.[6]
Item #2: Astronomers observing distant galaxies have found evidence that the source of mysterious large-scale magnetic fields is likely dark matter.[7]
Item #3: Researchers have demonstrated a magnetic switch that uses 6 picosecond (ps) electric pulses, about 100 times faster than current devices.[8]

Skeptical Quote of the Week ()
Science is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything. It has two rules. First: there are no sacred truths. All assumptions must be critically examined; arguments from authority are worthless. Second: whatever is inconsistent with the facts must be discarded or revised. ... The obvious is sometimes false; the unexpected is sometimes true.
