One Voice in the Cosmic Fugue

   1980    Science
Sagan discusses the story of the Heike crab and artificial selection of crabs resembling samurai warriors, as an opening into a larger discussion of evolution through natural selection (and the pitfalls of intelligent design). Among the topics are the development of life on the Cosmic Calendar and the Cambrian explosion; the function of DNA in growth; genetic replication, repairs, and mutation; the common biochemistry of terrestrial organisms; the creation of the molecules of life in the Miller-Urey experiment; and speculation on alien life (such as life in Jupiter's clouds). In the Cosmos Update ten years later, Sagan remarks on RNA also controlling chemical reactions and reproducing itself and the different roles of comets (potentially carrying organic molecules or causing the Cretaceous–Paleogene extinction event).

Inside the Social Network: Facebook Difficult Year

   2019    Technology
Facebook is a company that has grown from nothing to be worth half a trillion dollars in just 15 years. Today nearly a third of all humans are using it, and yet we rarely get to see the people actually in charge of the biggest social network in the world.
The company has suffered a series of deepening scandals and intense media scrutiny. In 2018, their mission - to connect everyone on the planet - seemed to be going dramatically wrong. Data leaks, fake news and hacks on user security were threatening to destroy everything Mark Zuckerberg had built.
Yet throughout this difficult time, the company allowed the filmakers to follow key members of the team trying to fix the problems and secure the platform. This film goes behind the scenes and follows the teams inside Facebook. It tackles difficult questions, like how our data is used and what content should and shouldn’t be on the site, but also shows how Facebook works, what the teams are doing to secure it, and reveals a hidden technological playground, where some of the smartest engineers in the world are being hired to build systems and technology no one has built before.

A Winning Design

   2002    Nature
A Winning Design clarifies what makes a mammal different from reptiles and birds. No, it isn't egg-laying: both the platypus and the echidna are egg-laying mammals; it's their ability to adapt. And it's this adaptability that becomes the crux of the remainder of the series. From the tiniest bat to the massive blue whale, all mammals share the ability to nurture their young on milk and regulate their own temperatures.

Is Poverty Genetic

   2014    Culture
Are the wealthy just born in the right place at the right time? Are the poor victims of a system designed to keep them down? Or do physics and biology determine who is rich and who is poor? Throughout history, distribution of wealth is governed by hidden forces: DNA, environmental stress, patterns of human migration and even the laws of thermodynamics! Nature seems to demand winners and losers in life. But does this mean greed is king, and the rich can take what they want? Or is cooperation – between microorganisms, monkeys, and humans – more essential to survival of a species?

The DNA Switch

   2019    Medicine    HD
Destiny is beyond our control, our fate already set, perhaps from the onset of disease or being born with a special ability. You may think our lives are determined by the genes we're born with, but that is not the case. In the non-coding 98% of our DNA, we have countless switches to promote or suppress the physiological reactions of our bodies. Interestingly, we can change the states of these switches through our own efforts and even can affect the DNA conditions of our offspring before their birth.

The Imposter

       History
In 1994, a thirteen year old boy disappeared from San Antonio, Texas. Three and a half years later, he is found alive and well thousands of miles away in a village in southern Spain with a story of kidnapping and torture. His family is overjoyed to bring him home. But all is not quite as it seems.
The boy bears many of the same distinguishing marks he always had, but why does he now have a strange accent? Why does he look so different? Any why doesn't the family seem to notice these glaring inconsistencies? It's only when an investigator starts asking questions that this strange tale takes an even stranger turn.
