Summary

This week: Italian scientists found a body of liquid water on mars using radar; a new study suggests that while dogs do feel empathy for us, training them to be therapy dogs doesn’t make them care more, it makes them more obedient; and research shows that military training can result in traumatic brain injuries even outside of combat.

0:00.0	It's Friday, July 27th, 2018, and you're listening to Up to Date, our weekly recap of science in the news.
0:08.7	I'm And I'm Kishore Hary.
0:11.4	We're recording this on a Wednesday, and just today...
0:14.2	Wait, wait, wait. I just told them it's Friday, Kishore.
0:16.8	Oh, shit.
0:17.8	The cat is out of the bag.
0:20.0	Just this week, we found a new source of water on Mars.
0:25.5	And that's really exciting because it's not just any old source of water.
0:30.0	It's a whole lake of water.
0:32.1	And it's actually still in water form.
0:35.1	It's actually not ice, which is what we've typically found before.
0:39.4	This one comes in a in kind of a sideways direction. There is a orbiting spacecraft called
0:46.0	the Mars Express, and it's using radar to evaluate the Martian landscape. And it passed over
0:51.7	the spot where they got a weird reflection back. And so they
0:56.0	started to analyze it and the onboard the spacecraft. It actually does some image processing
1:03.0	before it sends it back to Earth. And they saw something weird, but they couldn't figure out
1:07.8	what it was. So they had to do another pass over that area again.
1:12.4	And they saw the weird thing again, but it didn't add up to anything they'd seen.
1:16.4	So finally, scientists had the spacecraft send the raw data.
1:21.3	And when they got the raw data, it was really clear that there was a reflection coming
1:25.5	off of this area that the radar pattern indicated that there is a reflection coming off of this area that the radar pattern indicated
1:29.3	that there is a submerged lake here. And what's really exciting about this is it's similar in
