The Sound of a Ghost

By: Craig Childs | October 28, 2016

gothic-1662756_1280 The title of this post is not metaphorical nor is it a misleading hook. I’ve got a sound on tape. It could be a ghost. What is a ghost? Science says no such thing exists. But in these thinning days of autumn, even diehards might glance up startled. What was that?

If you want to skip this post and go straight to a spooky audio recording I picked up while covering a ghost hunting story, here it is:

However, I recommend you read this early Halloween entry first.

It starts with flashlights panning across Gothic effigies, lighting up figures in the walls above us. I wondered why the lights in the theater weren’t turned on, and now I knew. The shadows were stranger this way. You’d see things out of the corner of your eye, a face, a human body in a headdress with golden wings behind it, its face dark, eyes gleaming. Continue reading →

Killing in the Name of Science

By: Jessa Gamble | October 27, 2016

I open the lab door, flick on the light switch, and watch a herd of cockroaches scuttle for cover. It’s seven in the evening, when most of the university’s workers have left for the night. Even so, after I lift each rat from its cage, I place it in an unmarked black box, its temporary home for the journey from the sub-basement to the surgery room upstairs. Should anyone see me wheeling the box down the hall, they won’t be able to guess what’s inside. In fact, most people don’t know that my lab exists.

All is quiet in the surgery room except for the rustle of the nine rats. My fingers are sweating. Suddenly, I’m tired. I just want to go home. Swearing to myself, I move aside a jar of sterilized scalpels and reach for a Metallica CD. Gradually, the music hardens my mind as I mix chemicals behind a plastic shield. I can’t allow myself to think.

The first black box has an ID tag that reads JSmPFC1. Two months ago I injected a neurotoxin into this rat’s medial prefrontal cortex. I’ve finished testing the animal for learning problems, and now I have to check that I damaged exactly the right part of its brain. This requires a very specific procedure. I mark an X beside the ID number and open the box. His whiskers twitch inquisitively. He’s accustomed to my smell, and not so likely to bite as he was when he first arrived here as a 200 gram youngin’ from the breeding colonies.

The Eternal Toil of the Motor Protein

By: Cassandra Willyard | October 26, 2016

A few days ago, I stumbled across this particularly arresting GIF while scrolling through my Facebook feed. The animation shows a stringy figure with huge feet lugging a rippling green sphere along a ribbed beam. “Look at that little guy plodding along,” I thought. “That looks like hard work.”

Here’s the thing: That “little guy” is a motor protein called kinesin. His feet are actually heads. And he isn’t simply plodding. Kinesin is propelled down structures inside the cell called microtubules (that beam in the GIF) as its heads bind and release. Humans plod. Kinesin is driven by chemistry. Continue reading →

A Wolf Dies

“The Silver Lake Wolves” sounds like the title of a young adult novel, or possibly an indie rock band with lots of close harmony and beards. Actually, it was the name given by the Oregon Department of Fish and Wildlife (ODFW) and the US Fish and Wildlife Service (FWS) to a small family of wolves living near Silver Lake, Oregon, about 75 miles northeast of where I live in Klamath Falls. The family consisted of a male, known as OR 3, a female, known as OR 28, and a single pup. Earlier this month, someone killed OR 28. Because she lived in the western two-thirds of Oregon, she was protected by the Endangered Species Act. Killing her was a federal crime.

I’ve been covering wolves as a journalist for a few years now, and I’m endlessly fascinated by the complex ways we humans see them, relate to them, and interact with them. One clear tension is between seeing each wolf as an individual animal and looking at large numbers of wolves as a population. And the death of a single wolf in a small population tugs hard on that tension. Continue reading →

New Person of LWON: Emma Marris

By: Michelle Nijhuis | October 24, 2016

We’re so pleased that Emma Marris — author, journalist, interesting thinker, and LWON guest poster — has agreed to join us as a regular contributor. Emma is the author of Rambunctious Garden: Saving Nature in a Post-Wild World, and she’s written for National Geographic, Nature, Slate, and other publications. She recently gave an excellent TED talk that you really should watch, and won an NASW Science-in-Society Award for her Orion essay “Handle With Care.” She can also tell you exactly how to dress for the Peruvian rainforest.

Emma and her family live in southern Oregon, close to some of North America’s most rambunctious gardens. I’ve been lucky enough to camp out in a few of them with her, so I know she’s superfine company in the woods: smart, witty, thoughtful, and always fun to argue with. Please welcome Emma to our virtual campfire, and look for her first post tomorrow.

Redux: The Other Signs of Fall

By: Helen Fields | October 24, 2016

The other day I saw the fall crocuses and remembered that time last year when I learned that fall crocuses exist. Read on for my other signs of fall. What are yours?

The "most normal looking picture we managed" says my college friend Cameron, on Robert's first day of second grade and Max's first day of kindergarten. (The chicken has completed her formal education.) — “The most normal looking picture we managed” from college friend Cameron on Robert’s first day of second grade and Max’s first day of kindergarten. (Gladys the chicken has completed her formal education.)

The equinox is past. At last, fall has come to the northern hemisphere.

Some of the ways the new season shows up are obvious. The sunset creeps earlier and earlier as we race toward the winter solstice. The air cools. Pumpkin spice is in every product imaginable.

Others are subtler. There’s the spooky Halloween decoration store that opened near my office, and the equally scary specter of potential government shutdown.

Here are some of the nicest ways that the world has let me know we’re tilting away from the sun.

The Last Word

By: Jessa Gamble | October 21, 2016

$lyapunov-fractal$ October 17-21, 2016

Craig opened the week with a brave personal and scientific exploration of sexual assault’s effects on the brain and the psyche.

Revelations about Trump’s history with women warrants a revisit to Christie’s post on why harassment goes unreported.

Michelle plays detective in the extinction of an Australasian rodent. She finds that sometimes climate change as a cause of extinction is also an excuse that hides more proximal human causation.

Time travel is a recent thing to think about, says James Gleick, who has just spent more than four years writing a book about it. The idea of it, he concludes, is ultimately about eluding death.

Guest Brooke Borel, editor of a book on fact-checking, still finds herself tweeting first and asking questions later. Let her save you from the mistakes she has made.
