Follow-up experiments could add impurities to the ice. “We’ve done the experiments with pure ice,” Dr. Salzmann said. “The next question is, what will happen if we start mixing in other things?”Quote:

-109wind chill on mt washington
https://www.wmur.com/amp/article/met...ngton/42763378
Was just about to ask the collective, why does Mt Washington get so fucking cold when other, seemingly more rugged, places don’t touch those kinds of temps.Quote:

It does have the highest windspeed recorded on earth - and that was before the anenometer broke. That kinda tends to increase your wind chill number.
Very cool. Thanks guys.
Apparently it’s so cold in NE that trees are just spontaneously exploding which is both very cool and terrifying
Haven't seen (or heard!) any exploding trees but the harbor froze overnight, which I've never seen before.
Taking the dog for a short poop walk in the woods sounded like a firing range between the severe cold and strong winds making the trees "Pop" really loudly. The fast dive from near freezing to severe cold probably added to the effect.Quote:

Moore’s Law and the importance of investment in science
By the 50th anniversary of Moore’s Law in 2015, Intel estimated that the pace of innovation engendered by Moore’s Law had ushered in some $3 trillion in additional value to the U.S. gross domestic product over the prior 20 years. Moore’s Law had become the cornerstone of the semiconductor industry, and of the constantly evolving technologies that depend on it.
Critical to that engine of growth had been U.S. investment in basic research and STEM education, ten percent of the U.S. Federal Budget in 1968. By 2015, however, that had been reduced to a mere four percent. To Gordon, investment in discovery-driven science was another key impetus behind creating the Gordon and Betty Moore Foundation in 2000, especially in the context of a widening funding gap for something he recognized as critical to human progress.

A fascinating exploration of the origins of eukaryotic life, which for us dirty monkeys might be the second most important event in evolution after the origin of life itself.
https://www.science.org/doi/10.1126/sciadv.ade4973
An anaerobic excavate root raises interesting questions regarding the nature of the last eukaryote common ancestor (LECA) and the origin of mitochondria. If LECA had a respiratory-competent mitochondrion, as is widely held, then an early ancestor of each of the three anaerobic excavate lineages would have had to migrate independently to a low-oxygen environment. Meanwhile, each lineage would also have had to retain at least one fully mitochondriate branch that remained extant long enough to give rise to the next surviving split in the tree. However, there is now no evidence of any aerobic branch in any of the three anaerobic excavate groups. Each anaerobic excavate lineage would also have had to independently reduce their mitochondrion to nonrespiring hydrogenosomes or mitosomes [mitochondria-related organelles (MROs); (31)]. The latter at least is not, together, unlikely as multiple examples of such reductions have been documented in other eukaryotes (5, 32). However, a theoretically simpler explanation would be that the LECA simply had an MRO, most likely a hydrogenosome (33), and that mitochondrial respiration arose later, sometime after the divergence of Preaxostyla and before the emergence of Discoba (Fig. 3). This would suggest that aerobic mitochondria arose by a separate endosymbiosis from that which gave rise to hydrogenosomes.
...
Excluding taxa from the euArc tree means that we cannot rule out the possibility that one or more of these taxa, or other yet-undiscovered taxa, may represent earlier branches, given that much eukaryote diversity remains unknown (3, 7). However, no addition of taxa will change the fundamental relationship described here, i.e., that the earliest branches of extant eukaryotes include multiple anaerobic lineages with predominantly excavate morphology. The implications of this are profound. For example, eukaryotic cellular and molecular complexity probably predate mitochondrial respiration. Modern eukaryotes could also have arisen before the great oxygen event (4), which is consistent with recent molecular dating (5, 39).
I'm sorry, but I was around at the time and that's not what haopened.

"Researchers at Baylor College of Medicine have discovered a crucial regulator of the anti-cancer immune response that could change the game in the fight against cancer. Published in the Proceedings of the National Academy of Sciences, the study shows that in animal models of breast and prostate cancer, eliminating the gene SRC-3, specifically in a type of immune cell called regulatory T cells (Tregs), triggered a lifelong anti-cancer response that eradicated the tumor without the typical side effects observed with other therapies.
Furthermore, transferring Tregs without SRC-3 to animals carrying breast cancer tumors also resulted in long-term elimination of the tumor without negative side effects. The findings encourage pursuing further investigations to determine the value of this approach to treat the human disease."
^^^ I met Bert O' Malley when I interviewed for grad school at Baylor, thirty-plus years ago.
I requested to meet with him.
His office was rather ornate, with green carpeting and fancy furniture, I seem to recall.
He didn't really want to talk to me, just gave me a lecture at his white board about his lab's then current work on steroid hormone receptors. Nonetheless, I was very interested in going to Baylor and joining his lab.
But following my next visits to UCSD and Rockefeller, I pretty much forgot about BCM.

If you remove that check in the tumor microenvironment, that's great because over-abundance and/or over-activation of Tregs is associated with immune suppression in tumors. However if you do that systemically, you'll have aberrant CD8 T-cell activity. Mice aren't good for modeling that kind of thing.Quote:

So there are ripples in the space-time continuum. Ehh, we knew that, right?
That thread I linked above has a good update about the findings.
Apparently it confirms a lot of gravitational wave stuff that was only theorized, and hints to the existence of many more super-massive black holes than we first thought.
I think the real excitement is about the method and where it can go I. The future, some of which is discussed in that thread.
