Why we need to return Martian rock samples to Earth to test for signs of life

youtube.com/watch?v=tI9jiMUoXb…

This video turned out to be more interesting than I thought. And also kinda sad to see how current politics is negatively impacting science missions.

Thumbnail of the video from YouTube. You can see Becky on the left looking straight at you, holding her hand under her chin with a thinking expression on her face. On the right you see a Mars rover, with the background of a martian landscape covering the entire picture. The text on top reads "Can Mars rovers detect life on Earth?!" with the word Earth underlined.

Is water wet?

bbc.co.uk/programmes/w3ct5rjk

> The wetness of water seems obvious - but dive into the science and it's not so clear cut. We take a closer look at what wetness really is.

Answering this question turned out to be more interesting than I thought.

Perhaps there is something else happening on the 20th of every month giving her a que that it's that time, perhaps something she noticed on the day of her brother's passing so it reminds her of him. Either way, it's still pretty smart to be able to relate the memory of someone's death to something like that.... I'm sorry she passed away....

The Palestinian Buddhist Arrested by ICE

youtube.com/watch?v=FOCjZZhy4M…

It really makes me feel better to see interviews like this one, to see there are people out there trying to make a difference and their honesty about it all. And you should definitely raise your voice for people like Mohsen because what is being done to him is unjust and illegal.

Not the kind of videos that the YouTube algorithm likes to promote so I'm sharing it here....

They Didn't Make Dire Wolves, They Made Something…Else

I feel like this video is an important one to share. I'm glad he also shed some light on the importance of publicly funded research, people don't seem to realize just how much of the science that comes out of private companies are built on studies from academia.

Why Democracy Is Mathematically Impossible

youtube.com/watch?v=qf7ws2DF-z…

When we're talking about the flaws of democracy I think this is a big one, when our entire system of electing leaders has such fundamental flaws this will affect all aspects of politics.

Throughline: The Ghost in Your Phone

npr.org/2024/04/25/1198908739/…

It's hot. A mother works outside, a baby strapped to her back. The two of them breathe in toxic dust, day after day. And they're just two of thousands, cramped so close together it's hard to move, all facing down the mountain of cobalt stone. Cobalt mining is one of the world's most dangerous jobs. And it's also one of the most essential: cobalt is what powers the batteries in your smartphone, your laptop, the electric car you felt good about buying. More than three-quarters of the world's cobalt supply lies in the Democratic Republic of Congo, whose abundant resources have drawn greed and grifters for centuries. Today on the show: the fight for control of those resources, and for the dignity of the people who produce them.

Stuff You Should Know: Atomic Clocks, Ahoy!

> The only thing more complicated than an atomic clock is researching how they work and then figuring out how to explain it to other people. But believe us, they are fascinating. Even if you don’t care about clocks or atoms you’ll still like this episode.

This was a fun one to listen to.

99% Invisible: The Lost Subways of North America

99percentinvisible.org/episode…

Los Angeles actually used to have a massive electric railway system in the early 1900s, called the Red Car. Jake Berman, the author of The Lost Subways of North America, tells us about how, time after time, when North American cities seemed just inches away from having a robust, utopian future of fast, reliable, and convenient public transportation systems, something gets in the way. That thing is sometimes dysfunctional local politics, sometimes it’s bureaucracy. Sometimes it’s the way our infrastructure favors cars over mass transit, and too often, it’s racism.

99% Invisible: Towers of Silence

99percentinvisible.org/episode…

Situated right in downtown Mumbai, India is an area of about 55 acres of dense, overgrown forest. In one of the most populous cities in the world, this is a place where peacocks roam freely -- a space out of time. This forest is protected by a religious community. It has survived in a relatively undeveloped state in the middle of this gargantuan city. Importantly, it’s also home to an ancient tradition in crisis -- one that is central to the lives (and deaths) of a particular population.

There’s a certain point in this forest beyond which almost no one can step -- only special caretakers of these grounds can go any further. They go by many names: khandia, nassassalar, pallbearer, corpse bearer. Their work here is holy. They carry dead bodies to their final resting place – atop stone structures that stand gray against the lush green. These buildings are called Towers of Silence.
