Do Penguins Need Sweaters?

jumperpenguinI’m a lover of science and a devoted knitter. Science-related projects that appear on the internet and have to do with yarn find their way into my inbox. That means I am aware of the project in Glasgow to knit microbes for elementary schools. I am in love with that shawl that depicts the night sky in silver beads. The knitted version of a dissected rat with its innards showing? Yep, seen it. Also the frog.

Proof that I’m doing something right in my life: When my friends see a knitted piece of science, they think of me. Continue reading

The Last Word

This week, Christie told us that story she doesn’t tell. Then lots of other people flocked to the comments to tell theirs.

Guest poster Daniel O’Connell asked if there’s gold in them thar evolutionary hills.

Cameron wondered if deep-sea species will be soon be forced to have their own reality show.

Moose as invasive species? Yes, Jessa said, and there is only one apex predator who can take them down.

And Roberta mourned the remipede, a strange crustacean only discovered 35 years ago, but one that might not be around much longer.

 

A tiny cave creature, eyeless and deadly

Remipede

Joey Pakes was swimming in a cave in Mexico on July 4, 2008 when she spotted her first remipede. Pakes, a graduate student in biology at UC Berkeley, had seen pictures of these aquatic centipede-like creatures before. But when she encountered one in the wild, the experience was completely different. “They’re such graceful animals,” she recalls. “It stopped me and I felt a certain high… I coudn’t scream or go ‘Oh wow, look at this’ because I was underwater. So I was just really happy, and I just shared it with myself and watched it as long as I could. That was my Fourth of July.”

Remipedes are pale, leggy crustaceans, no more than a couple inches long, that dwell in caves filled with layers of saltwater and freshwater. Because these caves are completely dark, remipedes have no eyes. They often swim on their backs, paddling their many legs; their name comes from the Latin word for “oar-footed.”

Attack of the Killer Moose

“Did I ever tell you about the time I got charged by a moose?”

We were at the point in our camping trip where everyone was dusting off their close-encounters-with-wildlife stories.

“Now, Davis, don’t tell that story or we’re going to get into an argument,” warned his wife.

“She was downwind of the bear spray when I let it off,” explained Davis, not particularly apologetically.

Every Newfoundlander has a story or two about the danger of moose, the dominant ungulate on the island. There is roughly one moose for every three people there – the most intense moose density in the world – and the population continues to grow despite 22,000 being harvested yearly during hunting season.

Though bulls become curious and aggressive during rutting season in September, the biggest hazard is not of the charging, snorting variety. Continue reading

The story I won’t tell

BurgersWikiMedia

I was having lunch with a vegetarian friend recently, when I caught myself wanting to tell her the story. When you’re a vegetarian, a lot of people — friends, distant relatives, complete strangers — barrage you with the story. It starts like this: “Yeah, I tried going vegetarian once.” 

During my 13 years as a vegetarian, I heard every variation of the story, and they all followed the same arc. Due to some earnest concern like animal rights, the environmental consequences of meat production or the artery clogging properties of lard, the storytellers decided to give up meat. Things are fine for a while, until we reach the story’s conflict. The protagonists notice their muscles shriveling or curly, dark hair hair growing on the backs of their hands, or new bald spots appearing on the top of their heads. They can’t sleep or they sleep all the time, they find themselves deficient in vitamin woo, or they’re plagued by strange bowel movements (which they describe in graphic detail). Now the story’s hero must decide whether to stick to good intentions or resume the meat-eating. 

It’s never even close. The slab of beef that breaks the streak is the most mind-blowing thing that any human being has ever tasted, and the storyteller’s life is returned to balance once again. In closing, the protagonist will usually indulge in a bit of self-depreciation for being so naive as to attempt a life without bacon.

I’d heard more than a decade’s worth of these stories, and I’d always dismissed them as the desperate justifications of people who felt secretly guilty about eating slaughtered animals. I’d done the research and knew that vegetarian diets are perfectly healthy, so I’d always considered these tales a pile of bull honkey. Continue reading

Mare Incognitum

Lenox_Globe_(2)_BritannicaThis week, a great white shark named Lydia may be the first white shark seen crossing into the eastern Atlantic. Scientists tagged her a year ago in Florida; since then, she’s swum 19,000 miles and as of yesterday morning, she was about 1000 miles from the Irish coast.

White shark populations, along with those of many other shark species, are dwindling because of bycatch and other threats. The more we can learn about them, the better we can help protect them. But there’s a small part of me that wants to toss a fig leaf over Lydia’s sensor, so that something about her journey is still unknown. Continue reading

Guest Post: Put Your Money Where Darwin’s Mouth Is

DarwinStocks2

In the fourteen years that I’ve been teaching high school biology, I’ve been asked a lot of weird questions about evolution. But, until recently, I’ve not been asked whether Charles Darwin could make you rich. Is evolution good for business? In a recent debate, Bill Nye, the popular science educator, argued it is.

Actually, Nye first offered this argument against creationism in a Big Think interview from August, 2012 entitled, “Creationism Is Not Appropriate For Children”.  Nye claimed that evolution deniers promote a worldview that is not just ignorant and inaccurate, but positively harmful—especially for children. Since creationism interferes with the public’s understanding of a fundamental and well-established scientific fact, Nye argued, it undermines our economic competiveness. “We need scientifically literate voters and taxpayers for the future [and] we need engineers that can build stuff– solve problems.”

Eight days later, the Creation Museum published a video response.  Continue reading

This week, Ann’s love letter to the capital weather gang made me want to understand far more about the weather.

You can either be totally secure, or you can be plugged into a network. Pick one, says Abstruse Goose.

Helen says art about the Artic ice melt is beautiful and awful, which is not the same thing as depressing.

Richard’s first day in journalism is the day the Chicago Tribune releases 274,000 words of Watergate. There’s an unexpected cliffhanger.

So why did Harry say what he did? The answer lies in something none of you, dear LWON readers, ever knew about Kepler.
