Science, Spoken

This story begins thousands of feet up in the air with migratory birds, and ends with a robotic fish swimming through the water below. To prepare for their journeys, birds fatten up big time, perhaps doubling their weight, essentially turning themselves into feathered batteries. Over many days and many miles, they burn that energy reserve to power their wings and keep themselves from starving and freezing. Eventually they reach their destinations emaciated.

The flooding that devastated the Midwest this spring damaged infrastructure and prevented farmers from getting crops planted on time. Though scientists can’t say if one storm or one wet season is the result of climate change, so far this year’s heavy rains are a perfect illustration of what scientific models of climate change predict for the region. And it’s only going to get more intense.

I was fairly impressed with the first episode of Savage Builds, which is now airing on the Discovery Channel. It's basically a show that lets Adam Savage (from MythBusters) do whatever he wants. In this case, he attempts to build an actual real-life Iron Man suit. SPOILER ALERT: He mostly succeeds. This is accomplished by printing out Iron Man armor pieces in titanium and then adding the jet suit from Gravity Industries on top of that. Yes, there is a real-life flying suit.

Eleanor Lutz has a running list of scientific topics she wants to find data sets for. It’s not her job exactly. A biologist with wide-ranging curiosity, Lutz moonlights as a data-driven illustrator who transforms public data sets into arrestingly beautiful visual objects. She’s made digital trading cards of animated viruses (who knew HPV could be so mesmerizing), and infographics on plant species that have evolved to withstand forest fires.

Later this month, a small satellite will hitch a ride on a SpaceX Falcon Heavy rocket for the world’s first demonstration of “green” satellite propellant in space. The satellite is fueled by AFM-315, which the Air Force first developed more than 20 years ago as an alternative to the typical satellite juice of choice, hydrazine.

The image is hard to look at now without crying: a thick red scar, carved across Gabriele Grunewald’s midriff as she flies around the track. At first it looks like it shouldn’t be there; perhaps it’s just an out-of-place shadow. But soon it becomes obvious what it truly is: a symbol of perseverance and pain.

It’s hard to feel sorry for the California utility PG&E, considering that officials blamed its equipment for starting nearly every major fire in the state in 2017. Last year, it was responsible for igniting the Camp Fire, which killed 85 and destroyed almost 20,000 structures. The problem is typically wind, which jostles electric lines, raining sparks onto parched vegetation below. So just cut the power when it’s particularly hot and dry and windy, right? If only it were so easy.

It's amazing that we can get electrical power just from the wind, but that's exactly what happens with a wind farm. It's a collection of wind turbines in a particular location with abundant wind. And as with many things, bigger is better. The Hornsea Wind Farm, for example, is being built 75 miles off the coast of Yorkshire, England, and upon completion it is expected to be the biggest offshore wind farm in the world.

In 1961—the year before he became the anchorman for CBS News—Walter Cronkite visited Camp Century, an unusual military compound on the Greenland ice sheet. Carved under the snow and ice, Camp Century had a main street and prefab housing for 250 soldiers and scientists—all powered by a pint-sized nuclear reactor.

So you have $52 million burning a hole in your pocket and just can’t decide what to do with it. Buy a private island? Too cliche. A new McLaren? You have enough of those. Pay off college administrators? Your kids have already graduated.
