Secret Lives of Neutrinos

   2021    Science
Our world, our solar system, our universe, none of it would exist without a ghostly particle called the neutrino. They are our early warning system whenever there's trouble in the universe. Neutrinos trigger star-killing explosions, supernovas. Neutrinos can answer so many questions, from why do we exist to how was the universe created. Neutrinos can be the very reason that we exist at all. The more we understand these elusive particles, the more we can gain insight into how the universe works.

Seasonal Worlds

   2022    Nature
Will explore the strategy, deception and feats of engineering plants use to thrive in the changing weather of different seasons. In the face of conditions ranging from ice and snow to raging fires, survival is often a question of perfect timing - particularly when contending with intense competition and surprising predators.
In this episode, David Attenborough travels to Finland to show one of the most extreme examples of seasonal plant life in the Arctic Circle. He also travels to California to see how climate change is affecting giant sequoias. These ancient trees like all other seasonal plants depend on the predictability of the seasons and our current changing climate threatens their survival.

The Homeless

   2022    History
The Chicago Tribune in late June of '42 reports the mass killing of Jews. Like many other newspapers, the Tribune puts it on page 6 or 7 in a tiny, little article. You either missed it, or if you saw it, you would say the editors don't think this is true. If they thought this was true, this would be on the front pages. Only a few of papers did put the story on the front page, including the Pittsburgh Courier.
The dominant idea in the American government is any act of rescue will be a diversion from the war effort. Both could've been done at the same time. In spite of that, a group of government officials supports and finances rescue operations. Allied soldiers begin to liberate concentration camps and find mass graves. The public sees the sheer scale of the Holocaust.
