"Isn't it weird that [thing humans commonly eat] is poisonous to literally every domesticated animal" I mean, there's a pretty good chance that [thing humans commonly eat] is at least mildly poisonous to humans, too. One of our quirks as a species is that we think our food is bland if it doesn't have enough poison in it.

Science hasn’t come up with a new way to be gay since the discovery of nonbinary identities over a decade ago. Worrisome.

The discovery represents a potential new way to recruit the immune system to fight treatment-resistant cancers using an iteration of mRNA technology and lipid nanoparticles, similar to COVID-19 vaccines, but with two key differences: use of a patient’s own tumor cells to create a personalized vaccine, and a newly engineered complex delivery mechanism within the vaccine.

Within 48 hours, the four human study participants showed remarkable results: their immune systems went into turbo cancer-destroying mode. And without surgery, radiation, or dangerous chemotherapy.

Folks, we may have a cure for cancer within your lifetime.

a post-doc was doing a guest seminar at my institute and at the beginning of his presentation he was explaining why he chose birds for his evolutionary analysis - so he said "well first of all, because birds are the best and most interesting animals and it's fun to study them" and a few professors in the room gave him a very serious nod

the twitter communists currently are getting mad because some random undergrads made an edible burrito tape bc they should instead be doing medical research

I think one fun side effect of studying uni level math is that simultaneously the complex numbers start seeming simpler than you thought but at the same time the real numbers are *way* more fucked up than you thought

"Milky Way black hole"

The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the center of our Galaxy: how it looks in polarized light.

This is the first time astronomers have been able to measure polarization, a signature of magnetic fields, this close to the edge of Sagittarius A*.

This image shows the polarized view of the Milky Way black hole. The lines mark the orientation of polarization, which is related to the magnetic field around the shadow of the black hole. Image

HOW WAS OUR SOLAR SYSTEM CREATED??

Blog#396

Saturday, April 27th, 2024.

Welcome back,

Here we are, 4.5 billion years into the lifetime of our sun, with an array of planets and smaller objects orbiting around it. How did all the planets form, and why did they end up in the orbits that they did?

The formation of the solar system is a challenging puzzle for modern astronomy and a terrific tale of extreme forces operating over immense timescales. Let's dig in.

I can't help but start with: In the beginning, there was nothing. But it wasn't quite nothing. All stars form from the collapse of nebulae, which are loose clouds of gas and dust, and our sun — and solar system — are no different. Astronomers call it the "pre-solar nebula" and of course it isn't around today, but we've seen enough solar systems forming throughout the galaxy to get the general picture.

But a nebula on its own won't collapse into a solar system without something to set it in motion. In our case, we can thank a nearby supernova explosion, whose shockwave ripped through the pre-solar nebula, causing it to begin its contraction.

We can tell that such a supernova went off nearby, because supernovae release great quantities of certain radioactive elements — elements that aren't normally found inside nebulae – but which we can see in our solar system today.

Once underway, the transition from nebula to solar system was irreversible. Over the course of millions of years, the nebula contracted and cooled, eventually reaching the point where a proto-sun was surrounded by a thin, rapidly rotating disk of gas and dust.

And then the fun began.

Four and a half billion years ago, our sun wasn't quite the shining star that it is today. It was compact and very, very hot, but it hadn't reached the critical densities and temperatures needed to sustain nuclear fusion in its core.

But while it was still in this embryonic stage, the planets began their slow waltzing formation.
