Double, double toil and trouble;

Reaction stir and oil bubble.

hey, your blog is super great and you seem like a beautiful human being. i find you to be super inspiring! i know you get a lot of these questions, but is it okay to punch boys who tell me that i "can't can't be an engineer because I'm a girl"?

Not that I’m advocating violence, but if hypothetically you were to punch a shitty dude for being sexist, you should aim for the solar plexus or the stomach, not the face, because you’re less likely to hurt your hand and you’ll do more damage. Hypothetically of course. 

At Biotech Party, Gender Diversity Means Cocktail Waitresses

Outside the Exploratorium, an airy event space on San Francisco’s waterfront, a long line of mostly male biotechnology investors and executives waited to get into a party.

The ballrooms of the Westin St. Francis hotel were packed with rows of men in blue and gray suits. Outside the hotel, where attendees gather for coffee, was about the same -- of 47 people sitting on one side of the square outside the conference hotel, two were women. Of those, one was in media relations. There was no line for the women’s bathroom.

LifeSci’s McDonald says it’s just reality that the industry and its investors skew male. That’s why he hired the models.

“When you think about going to a party, when you don’t have any models, it’s going to be 90/10, or even greater, male-to-female,” he said. “Adding in some females changes the dynamic quite a bit.”

Sighing is actually a life-saving reflex, and scientists have found the switch that controls it

Here's why we all need to be sighing 12 times an hour.

Remember all those times your parents told you it was rude to sigh? Well, you can discount that advice entirely, because sighing’s actually a crucial reflex that keeps our lungs healthy, and researchers have just uncovered the switch in our brain that controls it.

The team identified two tiny clusters of neurons in the brain stem that automatically turn normal breaths into sighs when our lungs need some extra help - and they do this roughly every 5 minutes (or 12 times an hour), regardless of whether or not you’re thinking about something depressing.

“Unlike a pacemaker that regulates only how fast we breathe, the brain’s breathing centre also controls the type of breath we take,” said one of the researchers, Mark Krasnow, from Stanford University School of Medicine.

This beautifully diverse group of sea slugs can be found in oceans worldwide, but its greatest variety is located in the magical habitat of warm, shallow reefs. It’s name comes from the Latin for “naked” (nudus), but it’s often informally called a “sea slug.” Today, a profile of a group of marine gastropods called Nudibranchia.

Unlike other mollusks (think snails), most nudibranchs have lost their shells, evolving other mechanisms for protection. For example, some are able to ingest and retain poisons found in prey, later secreting them for defense.

All known nudibranchs are carnivorous, feeding on a variety of sea life including sponges, other sea slugs, and barnacles. One species, Glaucus atlanticus, is known to prey on the Portuguese man o’ war!

Hermaphroditic, nudibranchs have a set of reproductive organs for both sexes, which means any creature can mate with another. That said, a nudibranch can’t fertilize itself.

According to National Geographic, “some nudibranchs are solar-powered, storing algae in their outer tissues and living off the sugars produced by the algae’s photosynthesis.”

The creature has very simple eyes (able to distinguish little more beyond light and dark), but have cephalic (head) tentacles that are sensitive to touch, taste, and smell. Its gills are uncovered, located behind their heart, and protrude in plumes on their back, making for a large surface area that grants more efficient oxygen exchange.
