The DART test was successful, it seems.
Bruce Willis should be proud.

Well aye, but a few years ago we landed on an asteroid and brought bits of it back to earth. ¯\_(ツ)_/¯

Well, it successfully impacted, which was impressive. How much it altered Dimorphos' orbit remains to be seen.

I'm still waiting for the imagery from the cubesat that DART deployed to watch its swandive, but ground-based telescopes have returned some pretty impressive images so far.

Nah he's too busy being pissed that Ben Affleck is banging his daughter.

They keep saying he has aphasia and that caused his dementia.
No ...doh.
He had a stroke that caused both aphasia and his other mental problems.

Quote:Purdue University chemists have discovered a mechanism for peptide-forming reactions to occur in water — something that has baffled scientists for decades.

“This is essentially the chemistry behind the origin of life,” said Graham Cooks. He is the Henry Bohn Hass Distinguished Professor of Analytical Chemistry in Purdue’s College of Science. “This is the first demonstration that primordial molecules, simple amino acids, spontaneously form peptides, the building blocks of life, in droplets of pure water. This is a dramatic discovery.”

This water-based chemistry, which leads to proteins and ultimately to life on Earth, could also lead to the faster development of medicines to treat humanity’s most debilitating diseases. The team’s discovery was published today (October 3, 2022) in the journal Proceedings of the National Academy of Sciences.

Scientists have theorized for decades that life on Earth began in the oceans. However, the chemistry behind this remained an enigma. Raw amino acids — something that meteorites delivered to early Earth daily — can react and latch together to form peptides. These are the building blocks of proteins and, eventually, life. Strangely, the process requires the loss of a water molecule, which seems exceedingly improbable in a wet, aqueous, or oceanic environment. For life to form, it required water. However, it also needed space away from the water.

Cooks, an expert in mass spectrometry and early Earth chemistry, and his research team have uncovered the answer to the riddle: “Water isn’t wet everywhere.” On the margins, where the water droplet meets the atmosphere, extremely quick reactions can take place, transforming abiotic amino acids into the building blocks of life. Therefore, fertile landscapes for life’s potential evolution were in places where sea spray flies into the air and waves pound the land, or where fresh water burbles down a slope.

The chemists have been using mass spectrometers to examine chemical reactions in droplets containing water for more than 10 years.

“The rates of reactions in droplets are anywhere from a hundred to a million times faster than the same chemicals reacting in bulk solution,” Cooks said.

The swift rates of these reactions make catalysts unnecessary, speeding up the reactions and, in the case of early Earth chemistry, making the evolution of life possible. Decades of scientific investigation have been focused on figuring out how this mechanism works. The secret of how life emerged on Earth can help scientists better understand why it happened and guide their search for life on other planets, or even moons.

So then, ... Tongue
It seems that a French researcher has discovered the origin of the Covid pandemic.
I wonder if she will get a Nobel ?

The James Webb telescope has seen 6 (massive) "objects" in the early universe which according to the present theories
should not have had time to form. Looks like the Standard Model will have to be altered.

Quote:Still, it might not be time to rewrite cosmology just yet: The researchers say it’s possible some of the objects could be obscured supermassive black holes, and that what appears to be starlight in the images could actually be gas and dust getting pulled in by their gravity Link.

It's a strange one alright, that's from February I'm surprised there's nothing else since the announcement.
