This Week in Science:

The big science stories this week included . . .

• Researchers training an A.I. to scan people’s brain activity, and translate it into text. With the goal of helping people like stoke victims communicate again.
• A recent brain-scan study could explain why people see a “light at the end of the tunnel” when they die. They found there’s a surge of brain activity in the last few minutes of life, and it’s possible it could cause visualizations and moments of consciousness.

And in booze news . . .

• The yeast used to make lagers, might have been created by mistake in a basement in Germany 400 years ago. They think white ale yeast mixed with brown beer yeast in a basement in Germany between 1602 and 1615. Now four centuries later, lagers account for 90% of beer sales worldwide.
• And experts in “fluid dynamics” finally figured out the physics behind champagne bubbles, and why they tend to rise in straight single-file lines, while bubbles in beer don’t. We could explain, but it’s complicated, so watch this video instead.
