panic! at the lab

i write scribbles not lab reports

nine in the afternoon (nine in the evening? morning?) (oh it’s a 12 hr time point)

mad as grad students

high hopes (dissertation version)

protestants: god is not an absent father! talk to god like a friend! god is always with you! bring your problems to god, no matter how small! it’s not at all weird to call god “daddy!”

catholics: god is far too important to give a fuck about your lost keys or your algebra exam. please address your petty concerns to one of god’s ten thousand holy secretaries. if it’s really important, consider asking his mom.

“What’s that on the beach?!" 

Monterey Bay beachcombers and divers were treated to a huge bloom of salps this weekend! Salps are gelatinous filter-feeders that drift with and feed in the plankton. Wind and waves sometimes blow these open-ocean emissaries onshore by the thousands, a feast for fishes, invertebrates—and for the eyes of curious naturalists!

There were several species of salps in this weekend’s bloom, including these in the genus Salpa. Salps do not sting—in fact, they’re more closely related to fishes and people than they are to other "jellies”! The brown/orange orb is the salp’s gut. Pumping muscle bands push water from one end of the animal to the other through an internal plankton-pasta strainer.

Salps have an incredibly successful reproductive strategy, allowing them to explode in numbers when conditions are right. Ready? Here we go: Salps can be found as solos, or as a chain of dozens of individuals attached together. Same species, two different body morphs. The solos produce the chain asexually, and the individuals in the chain are all clones. 

OK, still with us? The next part is a doozy: A young chain is female, and each female clone produces another solo salp from an egg that is fertilized by older male chains. The older male chains are female chains that changed sex as they aged—this is called sequential hermaphroditism. This whole process allows salps to produce new generations at an incredible rate, to take advantage of fleeting oceanic conditions. Phew, we did it!

Salps are thought to have an outsized effect on the flow of nutrients in the ocean’s food web. Because their fecal pellets sink, salp poop delivers vital nutrition from the ocean surface to the deep seafloor, and helps take carbon from the atmosphere to the deep, which helps regulate the planet’s climate. Spent salps from these huge blooms become food for countless organisms throughout the water column. Certain deep sea communities may even depend on these ephemeral feasts to survive in the desert of the abyssal plain, according to research by our colleagues at the Monterey Bay Aquarium Research Institute (MBARI).

This weekend’s salp bloom is a jiggly reminder of the vast community of gelatinous drifters—the gelata—that drift in the open ocean, connecting the surface to the deep and adjusting the Earth’s energy flow, unseen by most until a chance encounter on the shore.

Sofia Ionescu (1920-2008) was a Romanian neurosurgeon, thought to be one of the first female neurosurgeons in the world.

She studied medicine in Bucharest, and in 1943 became part of the first team of Romanian neurosurgeons. She continued practicing the profession for almost five decades and received numerous awards for her lifesaving work.

I just read that bees don't have lungs how do their respiratory system works??

Correct. Insects do not have lungs they breathe through spiracles (tiny openings) that can open and close, as well as having filters to keep dust and other external contaminants out. 

The spiracles run across their abdomen connecting to tracheae  which is where oxygen exchange takes place (In mammals this happens in the blood), that then connect to tracheole. The air sacs expand and collapse so force the air in the spiracles and into the trachea and almost function in that they can reserve air in them so insects can conserve water.

Honey bees have 10 pairs of spiracles, 3 pairs on the thorax and 7 pairs on the abdomen. Bees can use and accelerate the passage of air in their bodies via their air sacs, contacting them and increasing their respiration rate.

This adaptive function of their respiratory system actually helps them to fly and the first few spiracles are used for air to exit while the others for air entering, they also have valves to prevent backflow. This also allows the bee to cool down or heat up if it needs to, which is why you’ll see bees abdomens wiggling while they’re resting. They’re forcing air in and out of their bodies in order to rapidly cool down or heat up, which is important for flight.

My favorite Female Scientist by Drziggystardust

Mathematician, philosopher, astronomer- Mostly known for her work in mathematics because she is the first well documented woman in the field. Her life and work were so important that many scholars agree that her brutal murder by religious zealots marks the end of the Classical Antiquity era, at the very least her death marked the downfall of intellectual life in Alexandria.
