Megan Amram brings the sadlaughs on women and science

By on 3 Aug 2015commentsShare

Comedian, author, and self-advertised Harvard graduate Megan Amram is at it again — on her quest to bring science to us hot hobos, also known as women, she is launching a video series on “sexy science.” In the first episode of Experimenting with Megan Amram, Amram builds a (biological) potato clock and, more saliently, interviews engineer and Caltech aeronautics professor Beverley McKeon. Topics include: What’s it like to be the first female director of the Graduate Aerospace Laboratories at the California Institute of Technology? and, Do they have Miami in England? What about Beyoncé?

The bigger question in all this is: Is something like fluid dynamics easier for women to understand when framed as a discussion on air-drying your nails? Probably not! If anything, Amram’s antics draw attention to the clarity and confidence of her expert guest, and serve as a refutation of the perniciously prevalent idea that women can’t understand science and are really just around to look good.

Wind power could get its tax breaks back

Wind power could get its tax breaks back

By on 22 Jul 2015commentsShare

The GOP-controlled Senate Finance Committee did right by the clean energy industry yesterday when, as part of a big package of tax break extensions, it cleared the way for the renewal of a key tax credit that supports wind power.

The wind credit was effectively killed last year when an entire $85 billion package of tax breaks failed to make it through the Senate — in part because of GOP opposition to this particular wind energy credit.

In yesterday’s Senate Finance Committee vote, the tax credit package was approved by a vote of 23-3. GOP Sen. Pat Toomey (Penn.) was one of the naysayers on the wind credit, arguing that the it meddles with the energy economy. “We are simply picking winners and losers,” he said during a debate last year on the topic. (Fossil fuel companies get many more billions in tax credits and deductions, but whatever.)

Republican Sen. Chuck Grassley of Iowa, however, pushed for the wind credit extension. Iowa produces quite a bit of wind power. “I’ve worked to provide as much certainty as possible to grow the domestic wind industry,” Grassley wrote in a letter to the committee chair earlier this month. “I know firsthand the boom and bust cycle that exists for renewable energy producers when Congress fails to extend these critically important tax incentives.”

Tax breaks like these, which legislators don’t want to make permanent but also don’t want to eliminate altogether, often get renewed en masse in a vote that proves controversial every year. It creates quite a bit of uncertainty for affected industries; investors, for example, are more hesitant about putting their money into wind energy when they aren’t sure how taxes will affect wind producers’ bottom lines.

The package also includes tax credits for a range of industries, including some for big banks and one for Broadway musical producers. The credits would be assured through 2016, when the fight to renew them would begin again.

What’s next for this package of tax breaks isn’t clear. The full Senate has to vote on the package approved by the Senate Finance Committee. The House is considering a similar bill, but may end up doing it’s own thing: The Republican majority there wants to make some breaks permanent, but the wind energy tax credit, opposed by many conservatives, likely won’t be one of those. So who knows if the wind credit will ever make it into law again. Regardless: Progress!

This is likely when people started eating chicken

This is likely when people started eating chicken

By on 21 Jul 2015commentsShare

It’s meat month here at Grist, and we’re talking about everything from the sustainability of meat to the morality of meat to the butchering of meat to the future of meat (stay tuned). But have you ever wondered who was the first to gnaw on a juicy chicken leg and declare the inaugural “Tastes like chicken!”?

Well today, NPR reports that those culinary geniuses might have lived sometime between 400 and 200 B.C. in what is now an archaeological site called Maresha. Here’s more from NPR:

“The site is located on a trade route between Jerusalem and Egypt,” says Lee Perry-Gal, a doctoral student in the department of archaeology at the University of Haifa. As a result, it was a meeting place of cultures, “like New York City,” she says.

Not too long ago, the archaeologists unearthed something unusual: a collection of chicken bones.

“This was very, very surprising,” says Perry-Gal.

The surprising thing was not that chickens lived here. There’s evidence that humans have kept chickens around for thousands of years, starting in Southeast Asia and China.

But those older sites contained just a few scattered chicken bones. People were raising those chickens for cockfighting, or for special ceremonies. The birds apparently weren’t considered much of a food.

In Maresha, however, the archaeologists found thousands of well-preserved chicken bones, many of which had knife marks on them, and most of which came from female chickens. All of that, the researchers report in the Proceedings of the National Academy of Sciences, indicates that these people were raising chickens for food, not cockfighting.

It’s less clear, however, why these people decided to pick up that juicy leg. Here’s more from NPR:

Perry-Gal thinks that part of it must have been a shift in the way people thought about food. “This is a matter of culture,” she says. “You have to decide that you are eating chicken from now on.”

In the history of human cuisine, Maresha may mark a turning point.

Barely a century later, the Romans starting spreading the chicken-eating habit across their empire. “From this point on, we see chicken everywhere in Europe,” Perry-Gal says. “We see a bigger and bigger percent of chicken. It’s like a new cellphone. We see it everywhere.”

Now that we find ourselves buried up to our faces in chicken (and cellphones), perhaps we can take comfort in knowing that such drastic shifts are possible. Perhaps we can just decide that we’re not gonna raise animals in horrific conditions just so we can have our all-you-can-eat buffets and cheap burgers. Perhaps we can just decide that we’ll start eating insects or lab-grown meat or weird veggie-based imitation meat simply because it’s better for the planet. Now, before you call me a dewy-eyed optimist (I’m not — I think we’re pretty much all going to hell in a handbasket), stick around for the end of meat month, when we dive into all of these futuristic meat alternatives and assess their feasibility.

Big trouble ahead for ocean’s tiny microbes

Big trouble ahead for ocean’s tiny microbes

By on 20 Jul 2015commentsShare

It’s never good when a scientist says “I try not to be an alarmist, but …”

Unfortunately, that’s exactly what MIT’s Stephanie Dutkiewicz recently said about how ocean acidification and warming waters could massively disrupt the world’s phytoplankton populations, aka the base of the entire marine food web.

For a refresher on ocean acidification, check out this short Grist video featuring our office beta fish and a soda maker. Otherwise, here’s the gist: As the ocean absorbs CO2, it becomes more acidic. In the last 200 years or so, the ocean’s acidity has increased by about 30 percent, and scientists expect it to go up way more by the end of the century.

So Dutkiewicz, an oceanographer, and her colleagues wanted to know what exactly that would mean for all those cute little micro-plants floating around out there, and today, in a paper published online in the journal Nature Climate Change, they deliver the sobering news: Ocean acidification will likely kill off some phytoplankton species and let others thrive, while warming waters will likely cause mass phytoplankton migrations toward the poles. In short: The base of the marine food web could be in for some serious upheaval in the coming decades. Here’s more from MIT News:

“I’ve always been a total believer in climate change, and I try not to be an alarmist, because it’s not good for anyone,” says Dutkiewicz, who is the paper’s lead author. “But I was actually quite shocked by the results. The fact that there are so many different possible changes, that different phytoplankton respond differently, means there might be some quite traumatic changes in the communities over the course of the 21st century. A whole rearrangement of the communities means something to both the food web further up, but also for things like cycling of carbon.”

To get these results, Dutkiewicz and her colleagues studied 154 published experiments on how different types of phytoplankton respond to different acidity levels. They categorized certain species as “winners” and “losers” and then fed that information into a global ocean circulation model. Dutkiewicz told MIT News that more experiments need to be done on how multiple species interact under different acidity levels, but so far, things aren’t looking good:

“Generally, a polar bear eats things that start feeding on a diatom, and is probably not fed by something that feeds on Prochlorococcus, for example,” Dutkiewicz says. “The whole food chain is going to be different.”

On the plus side, we don’t like polar bears anymore, so perhaps this is all for the best.

John Oliver wants America to clean its plate

John Oliver wants America to clean its plate

By on 20 Jul 2015commentsShare

As Last Week Tonight host John Oliver suggests in the video above, what is more American than food waste? From farm to table to dump, Americans toss out up to a whopping 40 percent of it.

“Food waste is like the band Rascal Flatts,” jokes Oliver. “It can fill a surprising number of stadiums, even though many people consider it complete garbage.” It’s garbage for the climate too: Annual greenhouse gas emissions due to food waste add up to about twice the annual emissions of India.

Much of the dumping can be pinned to arbitrary sell-by dates and aesthetic criteria formally and informally governing the food that makes it to market. The Canadian regulatory text on apples, for example, runs upwards of 30 pages and covers everything from apple shape and firmness to hail injury and sunburn (which is apparently a thing that can happen to apples). Revising regulations like these and getting ugly produce onto the shelves could be a good first step toward curbing the waste trend.

There’s probably a food for thought joke to be made, but I’ll spare you.
