This Week in Science: Coffee Grounds, Moon Landings, and Piano Lessons

It’s time for “Nerd News,” covering the most important news for your brain.

Here’s a quick rundown of this week in science . . .

1.  India became the fourth country to land a ship on the moon, and the first to land at the moon’s south pole.  That’s important if we ever want a base, because there could be reserves of frozen water there.

Meanwhile, Russia also tried, but their ship crashed into the moon on Saturday.  It was their first lunar mission in 47 years.  (Besides India, the other countries that have made it to the moon are the U.S., the Soviet Union, and China.)

2.  In other space news:  The Space Station had to fire its thrusters again yesterday to avoid more space junk floating around up there.  And a study found it would take a minimum of 22 people to run a colony on Mars.

3.  In coffee news:  Researchers in Australia found you can make concrete 30% stronger by adding some old coffee grounds into the mix.

4.  In music news:  A study found making your kids take piano lessons could keep their minds sharper in old age.  Actually, any kind of music lessons help.
