The Last Word On Nothing

Taking the Waste out of Wastewater

By: Helen Fields | November 17, 2015

In a fenced-off corner of Washington, D.C, down at the very tip, where the city’s diamond shape meets the Potomac river, is a giant feeding station for gulls.

Ok, that’s not its main function. If you have ever pooped in DC, or in parts of four surrounding counties, including Dulles International Airport, you have helped support the birds at the Blue Plains Advanced Wastewater Treatment Plant. It’s run by DC Water, an agency that loads visitors like me into a tour van that says “DRINK TAP” on the side. For historic reasons, D.C.’s drinking water is actually treated by the Army Corps of Engineers, not DC Water. But DC Water handles pretty much everything else about it, including what happens to it after it’s been used.

“Used water” is the term preferred by engineer Bill Brower, the program manager for DC Water’s Biosolids Program and the leader of a tour of Blue Plains arranged on Sunday for a local science writing organization. “Enriched water” is another amusing euphemism. You see, “waste water” makes it sound like trash, Brower says, when actually they can get a lot out of the stuff from our toilets. (And, the system being how it is, from our sinks, dishwashers, washing machines, and, in the old parts of town, even the water that runs off the streets.) Continue reading →

Guest Post: The Return of Persian Science

By: Ramin Skibba | November 16, 2015

Like many multiethnic and multicultural people, I’ve had difficulty coming to terms with my multifaceted yet fragmented identity. As a half-Iranian in the midst of Americans, I’ve lacked key cultural influences and a US-centric worldview, while in Iran I feel like an outsider at times.

I’ve had the wonderful opportunity to visit twice so far—once as a teenager and once more recently as a physicist. Each time, I’ve been very observant in the hopes of better understanding an important side of myself. I’ve explored its fascinatingly unique cities, including the massive capital, Tehran, and its huge bazaars; Esfahan, with its spectacular architecture and Jahan Square, a national landmark; and Shiraz, with its tombs of poet giants, Hafez and Saadi. I’ve also looked for signs of how the country appears to be changing as it becomes more open to the international community.

At the invitation of Sohrab Rahvar, physics professor at the University of Sharif, I gave two seminars, one there and another at the University of Tehran. I presented postdoctoral research I was doing at the Max Planck Institute for Astronomy in Heidelberg, Germany, investigating connections between observations of galaxies and theories of dark matter.

The Last Word

By: Jennifer S. Holland | November 14, 2015

November 9-13

This week, guest poster Soren Wheeler shares why the chaos and failure inherent in science should be embraced in science education.

In a dispatch from China, I offer a glimpse into the fieldwork that, despite the roaches, makes my heart go pitter-pat.

Craig Childs exposes a secret of the cracked and desolate Atacama Desert: It comes, gloriously, to life.

During this week of Veteran’s Day, Michelle Nijhuis asks us to remember another kind of soldier, the environmental activist serving, and often dying, to protect the wild.

And Rose Eveleth considers whether the Internet is like the lead plumbing of ancient Rome, a tremendously useful tool that betters lives while slowly poisoning its users.

The Internet Is a Series of Lead Tubes

By: Rose Eveleth | November 13, 2015

Like many of you, I suspect, I have a love hate relationship with the internet. I love the access it gives me to all sorts of information, and how it connects me with people I would have never been able to hear from before. I hate how it also contains spaces for people to easily gather to abuse and harass people. I have made great, deep friends on the internet, and I have also wanted to burn the whole thing down.

A few months ago I talked to Finn Brunton, a digital historian at NYU, for an episode of my podcast Meanwhile in the Future. The episode was all about why we might, voluntarily and collectively, decide to abandon the internet. It’s a fun one, and you should listen if that kind of weird future speculation intrigues you. But Brunton also said something that didn’t make it into the podcast, but that I think about a lot now. It was an analogy for the internet, and how future us might think about our current internet world. Maybe, he said, the internet is like lead pipes in Rome.

Lives on the Line

By: Michelle Nijhuis | November 12, 2015

Last Saturday, in the Preah Vihear forest reserve in northern Cambodia, forest ranger Sieng Darong and police officer Sab Yoh confiscated some chainsaws from an illegal logging site. For them, it was routine work. Both had patrolled Cambodian forests for years, and were familiar with the country’s epidemic of illegal logging and wildlife poaching.

That night, they set up camp with two colleagues, planning to continue their patrol the following day. While they slept, an intruder armed with a high-powered weapon killed them both. Darong, 47, was survived by his wife and two daughters; Yoh, 28, is survived by his wife and daughter. One of their colleagues escaped, and the other is wounded but recovering.

Life on Another Planet, The Atacama in Bloom

By: Craig Childs | November 11, 2015

Rain has been falling on the driest non-polar desert in the world, famous for parts of it not seeing a drop of rain for centuries. The Atacama Desert in South America is caught in the rain shadow of the Andes on one side, and cold dry air washing in from an Antarctica ocean current on the other. This year, el Niño is on. Warmer waters are pushing against the West Coast of South America allowing rain to come to a rainless place. Last March, seven years of rain in a place that averages less than 4 millimeters a year fell overnight. The result has been an explosion of wildflowers, their seeds waiting in the hard dry soils for this very moment.

In August even more rain fell and a second even wilder bloom followed. A barren country where you can walk for days without seeing an ant, a fly, or a blade of grass erupted in a gloriously obscene display of flora.

I know the place in its other state: death. I went there for the desolation. I was writing about projections billions of years in the future when the sun begins to expand in one of its final acts. Naked under this searing light, oceans would boil away. The surface of the Atacama is all that remained, a barren floor of salt pillars lifeless pans. It was my end of the world. Continue reading →

A Squee from the Field: Why I Love my Job

By: Jennifer S. Holland | November 10, 2015

Sometimes, while out on the job, I have to pinch myself and think, ‘hold on to this moment.’ Because the moments that make up my workday can be truly fabulous.

Here’s what last week’s pinch was for: I was squatting on the ground at the Bifengxia panda base in central China, on a cloudy but pleasantly warm October morning, snapping pictures of some of the 18 tiny panda cubs that were lurching around in the grass. How tempting to reach a hand into that panda pile, but I held back, as I hadn’t gotten permission to pet them. Instead, I put my chin down low to the ground to watch the cubs at their level. One of them pulled itself toward me, checking me out with wide eyes and squeaking for attention as it would to its mother. It was, indeed, a very good moment.

At times like that, I don’t even try to keep my own squishy-happy-heart sounds to myself. The latest term I’ve heard for this feeling and the noise that accompanies it is “squee” (thanks, Facebook), and on panda-kindergarten day I was squeeing all over the place. (Not as messy as it sounds.) In fact, I’d say it was totally within my job description, right then, to squee. Continue reading →

Guest Post: Science Fail

By: Soren Wheeler | November 9, 2015

When I was in 4th grade, my teacher gave everyone in class an ice cube. Our task, she said, was to keep it from melting for as long as possible. In a room full of 10 year olds, that task turned into a heated competition. But I wasn’t worried. I’d had a stroke of insight: I knew the ice cube needed to stay cold, and it just so happened there was a sink in the back of the classroom with a limitless supply of cold water.

So I ran back to the sink, held my ice cube under the cold running water … and … watched in horror as it melted away in a matter of minutes. In fact, my ice cube was the first to melt. Even the kid who had just left his on the desk in front of him outlasted me. Continue reading →
