SUNDAY - "Great Migrations," the Latest Mega Nature Documentary

Premiering Sunday, November 7, on the National Geographic Channel: Great Migrations. Set your DVRs -- the seven-part series is set to air at 8pm.

We live in a wonderful era for nature documentaries. In recent years we've seen mega documentaries like Planet Earth and Life capture headlines, and with good reason -- they featured stunning HD photography, huge budgets, and a compelling narrative. The latest mega nature documentary is Great Migrations from National Geographic, and it's a doozy. This seven-part series is narrated by Alec Baldwin and features shockingly impressive photography, often tackling subjects that are really hard to photograph -- like tiny baby crabs, butterflies, ants, birds, as well as your standard large-mammal fare. Here's a sneak peek:

What Makes National Geographic Unique?

When I was a kid, the National Geographic magazine and television specials meant three things to me:

1. Awesome photography.

2. Great educational content.

3. A certain raw quality. (Remember sneaking peeks at the magazines that showed semi-nude ladies, from cultures where that was the norm?)

I'm happy to report that all of these qualities are preserved in Great Migrations. The only downside to #3 is that the documentary shows the brutal reality of nature: you see animals killing and eating each other. A shark rips a seal in half, filling the water with blood. Any time you see a lion or a crocodile, you can bet some young or weak animal is about to be eaten -- and you're going to see teeth sink into its neck as it goes down in slow motion. There's even a (comparatively tame) segment in which bald eagles rip apart frozen fish, just when you think they're going to attack a flock of other birds. My point is, this is an unflinching view of nature -- and it raises questions for parents who want to watch the program with young kids. You can either take this as an opportunity to discuss life and death with the kids, or watch the program on your own first, and then bring them in when you're sure they can handle it.

It really is a "circle of life" issue. In order for predator species to survive, they have to eat prey. This documentary is about migrating animals, which serve as prey for predators. That's not news. What is interesting is that the presentation is pretty stark, and this presents parents an opportunity to sit down with the kids and talk about life and death. I was honestly surprised by the amount of violence shown onscreen -- it's not gratuitous, but it's real. That is what makes this a National Geographic documentary, though -- they don't tone it down to make nature cuddly and safe. They show you when a member of the herd doesn't make it, and then they show you the rest of the herd as it struggles for survival.

The Donaghy Probletunity

Alec Baldwin narrates Great Migrations, and he does it well. (When Oprah Winfrey narrated the US version of Life there were howls of protest and many viewers refused to watch until the UK version with Attenborough's narration was released on Blu-ray; I don't think anyone can complain about Baldwin's exquisite narration -- it feels right, it sounds right, and it gives the documentary an extra flavor.) But what kept creeping into my brain was Baldwin's character Jack Donaghy from 30 Rock. My mind kept flipping between listening to Alec Baldwin narrating the documentary...then Jack Donaghy narrating the documentary. After all, Donaghy is a TV executive on 30 Rock whose main feature is excessive gravitas, as expressed through his trademark Baldwin Voice.

Personally, I found this delightful. Your kids aren't going to get it, and if you haven't seen 30 Rock you're not going to get it either. But if you're a 30 Rock fan, you will experience this cognitive flip, and I found it hilarious to listen to Jack Donaghy narrating the migration of wildebeests, elephants, and so on. In this unexpected way, you get two documentaries in one -- the serious version and the wink-wink-nudge-nudge version that Jack Donaghy provides. It's up to you to decide which one you're watching.

And because I couldn't resist, here's a clip showing part of the monarch butterfly narration, as narrated by Jack Donaghy, Vice President of East Coast Television and Microwave Oven Programming for General Electric. (He makes sure to mention how the butterflies save energy...perhaps a hidden sales pitch for GE microwaves.)

How Did They Do That?

Watching Great Migrations, it's hard not to pause, wondering how in the world they managed to get certain shots. They film the migration of monarch butterflies (also covered by this NOVA special), and you many photographers had to sit there next to a milkweed plant in order to get those shots? (This is actually explained in a Behind the Scenes episode as well as at this behind-the-scenes site.)

Time-lapse and slow motion are used to great effect, causing a lot of "wow" moments (I actually used saucier language, but you get the point). Some of the most memorable shots are underwater, with the two standouts being a brief segment on bioluminescent plankton, and an extended segment about red crabs (which are land creatures, but spawn in the sea).

Here's a clip from the red crab sequence, which they battle, I kid you not, "yellow crazy ants":

And here's some of that underwater footage I was talking about, followed by adorable baby crabs swarming over land. This is a tiny web video -- imagine this in full HD on your awesome TV.

This is a rare documentary in which the sheer beauty of insects and crustaceans, and the power of National Geographic's photography, makes them more relatable than mammals.

Senior producer David Hamlin, who shot the red crab sequence, explained it like so:

The aerial footage of some of these migrations is spectacular, but there is some stunning underwater photography of red crabs releasing their eggs, and then those eggs hatching. Can you talk a bit about what that shoot was like?

We filmed the red crabs on Christmas Island (between Australia and Indonesia). Once a year, when the monsoons arrive, nearly 50 million crabs march across the forest to the ocean. It's an incredible migration - one of my personal favorites. Frankly, this was the one migration I couldn't' miss - I just had to see it for myself. The year we filmed the crabs, the rains that triggered the annual migration were not as plentiful as in past years, so the crabs suffered during their walk. Open ground is death to them because the sun and heat dry up their lungs and they die. For red crabs, every drop of rain is quite literally a breath of fresh air. Another challenge in their race to the water's edge is what's known as yellow crazy ants. These invasive ants spray acid into the crabs' eyes rendering them blind, so that the crab can't move and dies in the sun.

The males arrive at the beach first and dig holes for the females, and a week later the females join them and burrow into those holes to grow their brood of up to 100,000 eggs. Then, something miraculous happens. Even though the female crabs are buried underground, they somehow know which night the moon is the smallest, and the tide therefore lowest, and they emerge from the earth, head down to the shoreline and into the water to release their eggs. The water is usually blue but it turns black with the amount of eggs.

Normally, when this migration happens, the eggs get dispersed all over the place and more often than not, they get eaten by fish and scattered by storms. It is only on every few years that the circumstances are favorable and the eggs make it back to the shoreline.

We were profoundly lucky - and prepared. We were able to see them hatching, and watch them emerge as tiny shrimp-like creature called megalops. But the real miracle is when millions of these tiny crablings emerge from the sea and overrun the beaches as they begin their own lifetime migrating back and forth, from the sea to the forest. It's breathtaking.

He's not overstating it (and you can see behind the scenes footage about this particular segment here). The red crab segment is stunning, breathtaking, you name it -- the sheer redness of the crabs on land to the bizarre and brilliantly colorful underwater footage are typical of Great Migrations. This is a documentary that will make you want to buy a bigger TV.

The Coffee Table Book

There's also a companion book featuring still photographs from the series, with a striking zebra photo on the cover. (Did you know that zebra stripe patterns are unique to each zebra? That's a little something I learned from watching Great Migrations.) The book stands on its own, and I've had it on my coffee table for a few weeks. Flipping through it, you're reminded again of what makes National Geographic so great: photography. The book is in stores now.

A Step-by-Step Journey Through Your Body's Digestive System

We at Mental Floss write a lot about poop, but not as often about how our bodies produce the stuff in the first place. Humans eat between two and six pounds of food per day—and as TED-Ed’s latest video explains, this grub passes through an elaborate network of channels, organs, tissues, and nerves that’s commonly known as the human digestive system.

The digestive system is the unsung hero of our torso. Its 10 organs—which include the esophagus, liver, intestines, and stomach—contain over 20 specialized cell types, and the gastrointestinal track alone has an internal surface area of between 320 and 430 square feet. But the digestive process doesn’t begin and end with the esophagus—it starts in our mouths.

The body produces just over six cups of saliva per day, a process that begins when we start salivating over a tasty morsel. This clear substance contains starch-busting enzymes, which break the food we eat into a moist lump (a bolus) that will eventually become the stuff that comes out our other ends. In all, this journey lasts between 30 and 40 hours—and you can follow it step by step by watching TED-Ed’s video below.

Today's Wine Glasses Are Almost Seven Times Larger Than They Were in 1700

Holiday party season (a.k.a. hangover season) is in full swing. While you likely have no one to blame but yourself for drinking that second (or third) pour at the office soiree, your glassware isn't doing you any favors—especially if you live in the UK. Vino vessels in England are nearly seven times larger today than they were in 1700, according to a new study spotted by Live Science. These findings were recently published in the English medical journal The BMJ.

Researchers at the University of Cambridge measured more than 400 wineglasses from the past three centuries to gauge whether glass size affects how much we drink. They dug deep into the history of parties past, perusing both the collections of the Ashmolean Museum of Art and Archaeology at the University of Oxford and the Royal Household's assemblage of glassware (a new set is commissioned for each monarch). They also scoured a vintage catalog, a modern department store, and eBay for examples.

After measuring these cups, researchers concluded that the average wineglass in 1700 held just 2.2 fluid ounces. For comparison's sake, that's the size of a double shot at a bar. Glasses today hold an average of 15.2 fluid ounces, even though a standard single serving size of wine is just 5 ounces.

Advances in technology and manufacturing are partly to blame for this increase, as is the wine industry. Marketing campaigns promoted the beverage as it increasingly became more affordable and available for purchase, which in turn prompted aficionados to opt for larger pours. Perhaps not surprisingly, this bigger-is-better mindset was also compounded by American drinking habits: Extra-large wineglasses became popular in the U.S. in the 1990s, prompting overseas manufacturers to follow suit.

Wine consumption in both England and America has risen dramatically since the 1960s [PDF]. Cambridge researchers noted that their study doesn't necessarily prove that the rise of super-sized glassware has led to this increase. But their findings do fit a larger trend: previous studies have found that larger plate size can increase food consumption. This might be because they skew our sense of perception, making us think we're consuming less than we actually are. And in the case of wine, in particular, oversized glasses could also heighten our sensory enjoyment, as they might release more of the drink's aroma.

“We cannot infer that the increase in glass size and the rise in wine consumption in England are causally linked,” the study's authors wrote. “Nor can we infer that reducing glass size would cut drinking. Our observation of increasing size does, however, draw attention to wine glass size as an area to investigate further in the context of population health.”
