If it Swims Like a Duck and Quacks Like a Duck Could Be a Hybrid of Two Duck Species

A duck is a duck, right? Well, yes, but when one duck mates with a duck of another species, there’s the risk that one of the original species could cease to exist. And then that duck is a duck no more.

This is not philosophical, as much as it is based on very real study that assesses the rate at which mallard and Mottled Ducks are combining into a hybrid species in the US. And whether or not this is a bad thing?

If This Wasp Stings You, ‘Just Lie Down and Start Screaming’

No kidding, the quote in this title is in a peer reviewed published paper. The tarantula wasp lives in the US, and apparently it’s sting is so painful it will end your happiness for the near future.

“There are some vivid descriptions of people getting stung by these things,” says invertebrate biologist Ben Hutchins of Texas Parks and Wildlife, “and their recommendation—and this was actually in a peer-reviewed journal—was to just lie down and start screaming, because few if any people could maintain verbal and physical coordination after getting stung by one of these things. You’re likely to just run off and hurt yourself. So just lie down and start yelling.”

That looks like a tall glass of NOPE!

Your butt is glowing: the most beautiful deathtrap of the glow worm

Glowworms (found primarily in New Zealand and Australia) live on the ceilings of caves and spin threads of silk covered with a sticky mucus. They cause these strings to glow, but triggering a chemical reaction with their butts. Which is kind of awesome.
After 6 to 12 months of eating whatever they can ensnare, the larvae transform into adults, which lack mouths and never eat. Their only job, in the final few days of their lives, is to mate and create the next generation of glowing-bottomed, trap making juveniles.Finally:

“And if you give them good vibrations, they’ll, er, get the excitations. There are some tours in New Zealand, Merritt tells me, where guides will deliberately hit the water or cave walls with an inflated inner tube; in response, the field of living stars will double in brightness. Merritt can achieve the same effect in his lab by pressing a vibrating cellphone against the aquarium where his captive glowworms live. “They really brighten up intensively if they detect vibration,” he says. “I’m not sure of the function.””

Birds Beware: Of the Praying Mantis?

“Tom Vaughan, a photographer then living in Colorado’s Mancos Valley, kept a hummingbird feeder outside his house. One morning, he stepped through the portico door and noticed a black-chinned hummingbird dangling from the side of the red plastic feeder like a stray Christmas ornament.

At first, Mr. Vaughan thought he knew what was going on. “I’d previously seen a hummingbird in a state of torpor,” he said, “when it was hanging straight down by its feet, regenerating its batteries, before dropping down and flying off.”

On closer inspection, Mr. Vaughan saw that the hummingbird was hanging not by its feet but by its head. And forget about jumping its batteries: the bird was in the grip of a three-inch-long green praying mantis.

The mantis was clinging with its back legs to the rim of the feeder, holding its feathered catch in its powerful, seemingly reverent front legs, and methodically chewing through the hummingbird’s skull to get at the nutritious brain tissue within.

“It was staring at me as it fed,” Mr. Vaughan said. “Of course, I took a picture of it.” Startled by the clicking shutter, the mantis dropped its partially decapitated meal, crawled under the feeder — and began menacing two hummingbirds on the other side.”

LGBTQ+ issues in STEM diversity: Diverse science = better science

Why does this matter? Because, to stay competitive in the world economy, America needs more scientists and engineers—and evidence shows that diversity may lead to better science.

Evidence suggests that diverse teams encourage more innovation and creativity, and may lead to better science. A 2014 article in Scientific American on “How Diversity Makes Us Smarter” notes that “simply interacting with individuals who are different forces group members to prepare better, to anticipate alternative viewpoints, and to expect that reaching consensus will take effort.”

And yet, the lack of data on LGBTQ+ careers in science leads to a silence that is discouraging from those same groups we are trying to incorporate.

The other side: I Love Being a Professor

Everyone I know is leaving academia. It started a few years ago with great postdocs taking alternative academic positions (head of an NSF institute, lead of a nature preserve, etc.), and has now progressed into most of my friends moving to industry (data science, start ups and biology industry).

So it’s really refreshing to read a post about someone who flat out loves their job. Maybe there is still hope?

The Sprint Towards the Finish Line

The last few entries in this series have been about how difficult graduate school is. The recent piece by 

“But with all of this attention paid to the “being miserable” part of grad school experience, we stopped talking about the things we need to talk about more. So here goes. Grad students, you are extremely worthy and accomplished. Getting into grad school demands hard work, dedication, stubbornness, and sheer skill. You’re here because someone saw something in you, and decided to help you nurture it. You may not know what this someone saw in you; this someone may not know it either. But it’s here. Your mental health matters.”

This week’s advice is about the hardest part of graduate school, the final sprint. In the American PhD, the last year, and especially, the last few months, are by far the hardest*. So here are some tips/things to think about to get through:

  1. The main thing is keeping “the main thing” the MAIN thing. This is catchy and easy to remember. It is also a nice way to say, “stop procrastinating”. Do you really think that alphabetizing your students’ test scores is a good use of your time? Or writing four different versions of that quiz for your students? I hate to tell you this, but you’re avoiding writing/finishing your dissertation. Those things seem important, but that’s because you are blinded by your need to do anything except the main thing. Keep that main thing the main thing.
  2. Remember, it doesn’t have to be perfect, it just has to be finished. This is the biggest misconception, as graduate students tend to be perfectionists.  The belief is that the submitted thesis/dissertation is the height of perfection. NO. Perfect is for Michaelangelo and the Sistene Chapel (and x-rays tell us a lot about the layers underneath the final paintings of a lot of masters). What the thesis/dissertation needs to be is finished. Stop spending your time crafting perfect sentences and perfect figures. Make sure they are good enough, and then move on. As much as you think it’s critical to make sure that last little bit of the figure looks so perfect your advisor will cry, that extra time you are spending is actually procrastinating.
  3. Communicate with your committee as much as they are willing. Yes, they are super busy with important jobs. Spoiler alert: one of those jobs is helping you finish. The last thing you want when you walk into your defense is a surprise. SURPRISE that one of your committee members doesn’t like any of your analyses. SURPRISE that another one thinks the entire dissertation needs to be rewritten. SURPRISE that one of your committee members is going to grill you during your defense. Each of these are real situations that people I know have experienced.  Each of these likely could have been alleviated by talking to their committee members ahead of time. Make sure you and your advisors are all on the same page, and address any concerns they have with your dissertation BEFORE you are in the room.
  4. Just keep swimming. I must have said this a million times towards the end. Yes, it’s a saying from Finding Nemo (an excellent movie for any biologist) and yes, it’s a kids movie (my previous statement stands). But it really does help; you just have to keep your head down and keep going. It’s tiring and exhausting but you’ll get there!
  5. Support each other. This one seems obvious, but it’s worth saying. This may be the final sprint, but remember you wouldn’t have gotten here without support, and you’re unlikely to finish without it. Make dinner for someone who’s close to the end, or take care of laundry, or be a shoulder to lean on. And when you’re close, don’t be afraid to ask for help. Team effort all the way.

So good luck, and remember, it gets better. No, but seriously, after you finish tipping the celebratory drink and sleep a lot (this was the best part  -. I left my “congratulations you finished” party early so I could sleep soundly for the first time in months), the “post PhD” life is way better than the “pre PhD” life. It really does get better!

*One of the interesting thing about living abroad is noticing the difference between earning a PhD in America and earning one in Europe.  I’ve recently talked my colleague here to describe the difference, and here I’m explicitly talking about the end of the American PhD (the European one has a different and more drawn out ending).
