💁🏻♀️ TIL: ☄️🧂 A #meteorite that crashed through a #NewJersey home in 2024 contained preserved salts and organic compounds from its parent #asteroid, evidence of ancient brines interacting with #carbon #chemistry.
Researchers found amino acids and other #prebiotic #molecules in the rock. The findings offer new clues about how life’s building blocks may have been delivered to early #Earth.

💁🏻♀️ TIL: 🧈🔬 At #Drexel University, a #food scientist explains how #butter and #margarine differ at the molecular level and why that matters for your #cookies.
Butter’s saturated #fats stack tightly for flaky baked goods, while margarine’s unsaturated fats get chemically rearranged to melt more predictably. The difference comes down to fatty acid chain structure.

Some folks built this thing, and things happened, and now, here it is on your computer or smartphone. I know we're not in the Matrix because the Matrix couldn't be this weird. Real life is real ❤️

👃🧬 Scientists are using cryo-electron #microscopy to visualize how scent #molecules bind to receptors in the nose.
The structural details help explain how the #brain distinguishes between thousands of different odors based on molecular shape and #chemistry. The findings provide a clearer understanding of the biological process that allows us to experience the world through smell.

I’m carbon 🧪
I don’t like being alone, I need to form bonds, and my favorite way is with four hydrogens 🤝
That’s how I complete my life structure—stable, satisfied, and always forming connections in a perfect 3D shape called tetrahedral geometry 🤯
In chemistry, I don’t just exist… I bond to survive 🔬

Here is a problem that has been quietly gnawing at astronomers for decades.
The standard approach to detecting #life on other worlds involves scanning #exoplanet #atmospheres for #oxygen, #methane, and #ozone, whose presence is difficult to explain without #biology.
It's a clever idea, but it carries a hidden flaw. That entire shopping list was written by studying Earth. It is, inevitably, a search for life like us.
The list of ways that #chemistry alone can accidentally mimic these #biosignature gases is growing faster than the list of new ways to detect life.
Each new false positive scenario demands even more information about the #planet to rule it out, and there is a genuine question about whether that information can ever be gathered exhaustively.
But there is a solution.
#Assembly theory doesn't ask what #molecules are present in an #atmosphere. Instead, it asks how hard they were to make.
Every molecule can be assigned an assembly index, a minimum number of construction steps required to build it from basic #chemical building blocks.
Simple molecules are easy to assemble by chance, but truly complex ones, requiring many sequential steps, don't arise without something doing a great deal of deliberate selection.
That something would then be life itself.

Organic #molecules delivered from #extraterrestrial materials may have played a key role in supplying building blocks for #life on #Earth.
Now scientists report all five canonical #nucleobases—purines (#adenine and #guanine) and pyrimidines (#cytosine, #thymine and #uracil)—in samples returned from the C-type #asteroid (162173) #Ryugu.
Samples from Ryugu, #Bennu and #Orgueil, which have a similar mineralogy and elemental composition, show purine-to-pyrimidine ratios negatively correlating with #ammonia.
These observations indicate that the nucleobases in these samples may have formed via a shared pathway depending on the physicochemical environment of the respective parent bodies.
The detection of diverse nucleobases in asteroid and meteorite materials demonstrates their widespread presence throughout the Solar System and reinforces the hypothesis that carbonaceous asteroids contributed to the #prebiotic chemical inventory of early Earth.

"n a study published in Nature Astronomy today, a team of Japanese scientists has confirmed all five nucleobases are present in this pristine asteroid [Ryugu] material.
This means these ingredients for life may have been widespread throughout the Solar System in its early years."
