Documentaries I Like: Frontline

Frontline screenshotFrontline is a PBS documentary series that has consistently offered the best reporting on a huge range of topics for over 25 years. Since 1983, Frontline has produced more than 480 documentaries on everything from politics to religion to personal finance. I can enthusiastically say Frontline produces documentaries I like, though I will caution that their war coverage in recent years has been so grim that it's often hard to watch.

Starting in 1995, Frontline took much of its programming online, producing in-depth websites as companion pieces to the televised documentaries. You can watch tons of Frontline programs in high-quality streaming video online -- for free! (Go PBS.) Go check out the Frontline archives, or pick one of my favorites:

A Class Divided (1985)

One day in 1968, Jane Elliott, a teacher in a small, all-white Iowa town, divided her third-grade class into blue-eyed and brown-eyed groups and gave them a daring lesson in discrimination. This is the story of that lesson, its lasting impact on the children, and its enduring power thirty years later.

HEAT (2008)

A global investigation into one of the greatest crises that mankind has ever faced -- Can we roll back global warming?

Melting glaciers, rising sea levels, fires, floods and droughts. On the eve of a historic election, award-winning producer and correspondent Martin Smith investigates how the world's largest corporations and governments are responding to Earth's looming environmental disaster.

"I have reported on the Cold War, the breakup of the Soviet Union, the rise of Al Qaeda, and the wars in Iraq and Afghanistan," says Smith. "But nothing matches climate change in scope and severity."

Secret History of the Credit Card (2004)

In "Secret History of the Credit Card," FRONTLINE and The New York Times join forces to investigate an industry few Americans fully understand. In this one-hour report, correspondent Lowell Bergman uncovers the techniques used by the industry to earn record profits and get consumers to take on more debt.

"The almost magical convenience of plastic money is critical to our famously compulsive consumer economy," Bergman says. "With more than 641 million credit cards in circulation and accounting for an estimated $1.5 trillion of consumer spending, the U.S. economy has clearly gone plastic."

How a Particle Accelerator Is Helping to Unearth Long-Lost Pieces of Art

A particle accelerator is revealing the people in 150-year-old photographs whose features had been lost to time, Science News reports.

For the first time, Madalena Kozachuk, a Ph.D. candidate at Canada’s Western University, and a team of scientists used an accelerator called a synchrotron to scan daguerreotypes, an ancestor of modern photography.

Invented by French painter and physicist Louis Daguerre, daguerreotypes were popular from around the 1840s to the 1860s. They were created by exposing an iodized silver-coated copper plate to a camera (the iodine helped make the plate's surface light-sensitive). Subjects had to sit in front of the camera for 20 to 30 minutes to set the portrait, down from the eight hours it took before Daguerre perfected his method. Photographers could then develop and fix the image with a combination of mercury and table salt.

Because they’re made of metal, though, daguerreotypes are prone to tarnish. Scientists can sometimes recover historical daguerreotypes by analyzing samples taken from their surface, but such attempts are often both destructive and futile, Kozachuk wrote in a study published in Scientific Reports.

Kozachuk found that using a particle accelerator is a less invasive and more accurate method. While some scientists have used X-ray imaging machines to digitally scan other historical objects, such instruments are too large to scan daguerreotypes. Reading the subtle variations on a daguerreotype surface requires a micron-level beam that only a particle accelerator can currently produce. By tracing the pattern of mercury deposits in the tarnished plate, the researchers were able to reveal the obscured image and create a digital photo of what the daguerrotype looked like when it was first made.

“When the image became apparent, it was jaw-dropping,” Kozachuk told Science News. “I squealed when the first face popped up.”

Scanning one square centimeter of each 8-by-7 centimeter plate took about eight hours. The technique, though time-intensive, may allow museums and collectors to restore old daguerreotypes with minimal damage.

“The ability to recover lost images will enable museums to expand their understanding of daguerreotype collections, as severely degraded plates would not otherwise have been able to be studied or viewed by interested scholars,” Kozachuk wrote.

This Scientist's Idea of the 'Perfect' Human Body Is Kind of Terrifying

The perfect human body has the legs of an ostrich, the heart of a dog, and the eyes of an octopus, according to anatomist Alice Roberts. And it’s utterly terrifying.

With the help of anatomical artist Scott Eaton and special effects designer Sangeet Prabhaker, Roberts created a life-size replica of herself that fixes many design flaws inherent to the human body, Motherboard reports. Roberts unveiled the sculpture on April 23 at the Science Museum in London. On June 13, the BBC released a documentary about the project.

Among the flaws Roberts’s sculpture corrects are humans’ inferior ears, spine, and lungs. Roberts borrowed anatomy from reptiles, birds, and other mammals to create a Frankenstein-esque creature straight from the island of Dr. Moreau.

The sculpture has legs like an ostrich because, as Roberts says on her website, the human knee is complex and prone to failure. Like humans, ostriches are bipedal, but they are far better runners. Bird-like lungs that keep air flowing in one direction, not two, make running and other aerobic activities easier for the perfect human to manage. And a chimpanzee’s sturdier spine and a dog’s heart (which has more connected arteries, leading to lower heart attack risk) make Roberts’s alternate self more resistant to injury and disease.

Roberts’s ideal human body also has skin like a frog that can change shades based on the environment, and large, bat-like ears that amplify sound. Roberts also fixed humans’ backwards retina, which produces a natural blind spot, by borrowing from octopus eye anatomy.

Perhaps most disturbing of all is the baby head poking out of the sculpture’s marsupial pouch. Roberts says marsupial pregnancy would be far easier on the human body and more convenient for parents on the go.

“This could be a human fit for the future,” Roberts says at the end of a trailer for her BBC documentary.
