Thursday, June 11th

Gorgeous morning in the library to review for my last final of the year. Class is machine learning, and my brain is swimming in algorithms.

Hope everyone has a great end of the week and enjoys the weather wherever you are!

this blog is me trying to motivate myself to be a better uni student. my time management is shit and i have a hard time studying and not just scrambling to do homework. i know how to do better. i know i can do better. do better with me.

The Medical Foam That Works like Fix-A-Flat But For Humans.

It is called ResQFoam, which was specifically created for battlefield injuries and sought to stop non-compressible abdominal hemorrhage, the leading cause of potentially preventable death in combat. The first human use was for a 34-year-old man in Alabama with severe shock after a motor vehicle crash. He had no detectable blood pressure, a weak pulse, & life-threatening abdominal bleeding. After the foam was deployed in his abdomen, his blood pressure improved & he survived surgery & was discharged. ResQFoam is a two-part, rapidly expanding polyurethane foam to treat non-compressible abdominal hemorrhage—the kind of internal bleeding you cannot stop with pressure or tourniquets.

It is made of 2 liquid polyurethane precursors, an isocyanate component, methylene diphenyl diisocyanate or toluene diisocyanate, that reacts with a polyol component such as polypropylene glycol that reacts to form the expanding, rigid polyurethane that expands inside the abdomen & stops internal bleeding. It takes just seconds for the foam to expand several times its original volume. The foam expands around organs, conforming to their shapes. It displaces pooled blood, stabilizes clots, & doesn't absorb blood & collapse. This buys critical time—often 1-3 hours—for transport to surgery. Survival jumps from 10% to 100% at 1 hour in severe liver injury.

In the OR, surgeons make an incision & remove the foam as a solid mass, & then surgeons repair the underlying injuries. Up to 50% of abdominal trauma deaths are preventable with timely bleeding control because patients can lose 1.6 quarts (1.5 L) of blood in 10 minutes. ResQFoam bridges the gap between injury & surgery.

Four astronauts, four bone marrows, one lunar testbed.

The 4 Artemis astronauts are taking their bone marrow, made from their cells, on a handful of chips the size of a USB thumb drive, known as "organ chips." They are completely functional as living bone marrow. While out in deep space, the astronauts will be showered by intense radiation—not just from our Sun, but from the rest of the cosmos. The bone marrow organ chips will provide a precise measure of how that radiation impacts a fundamental part of biology. Bone marrow is the body's blood cell factory, producing red blood cells, white blood cells, & platelets. The bone marrow produces hundreds of billions of cells every day. That's on the order of the number of stars in the Milky Way. Because these systems are highly sensitive to radiation, marrow acts as an early warning "bellwether" for health risks in deep space. The experiment is being called AVATAR for "A Virtual Astronaut Tissue Analog Response."

We already know spaceflight does strange things to the human body. Without gravity, load-bearing bones like your legs & spine do less work, which reduces density. Muscles lose mass. Neurological networks become befuddled by the lack of clear orientation. & floating about. The backs of their eyes can swell up. Their heart starts beating out of sync, & their ability to process oxygen drops. It becomes harder to go to the bathroom, & the immune system weakens, allowing dormant conditions to come to the fore or opportunistic, hitchhiking microbes to attack them more effectively. A few experiments aboard the Artemis II will chronicle changes to their immune system & their ability to perform both as individuals & as a team.

Organ chips are not new. These are collections of cell types through which fluids can flow, simulating a living creature or person. If it's a lung on a chip, it literally breathes. If it's a heart, it functions with the same electrical output that a heart tissue would. This is the first time that we're going to have a crew with their matched organ chips. This experiment will help identify health risks to the blood & immune systems during long missions. It will establish countermeasures such as drugs, shielding strategies, & mission protocols. It'll create personalized medical kits catered to each astronaut's biological vulnerabilities. You can't just send every type of medicine into space, not least because small increases in mass equate to large increases in launch costs. After the mission, scientists will perform single-cell RNA sequencing to see how blood-cell development changed at the genetic level.

Thanks to Wiseman, Glover, Koch & Hansen, we'll know a lot more than we ever did before. We could even send organ chips on missions ahead of time, made from crew members, to understand what biological, genetic & physical changes might happen. If AVATAR succeeds, it won't just be NASA's triumph. It'll be important to everyone. The same data can improve biomedical technology, develop personalized medicine and drug response prediction, comprehend aging and immune decline, and advance cancer treatment on Earth. It'll also be important to scientists, engineers & even bougie tourists with dreams of bouncing across the Moon.

[titistem]

Things included in my report that had to be fixed before turning it in, that 3 project members had already okayed!

More than half of the figures missing a caption and number,

Those that did have a number were wrongly numbered,

three dots for someone to later add info to that was still not added.

No periods at the end of a sentence

Incoherent sentences like in general

And the worst results known to mankind

i dont think we’re gonna pass this one folks

Painless skin patch offers new way to monitor immune health

Researchers at The Jackson Laboratory (JAX), in collaboration with the Massachusetts Institute of Technology (MIT), have developed the first bandage-like microneedle patch that can sample the body’s immune responses painlessly from the skin. The device detects inflammatory signals within minutes and collects specialized immune cells within hours without the need for blood draws or surgical…
