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?”

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.

[cat in january]

Couple reasons. It has a staffed weather station on top so we keep track of it all the time. Lots of places get colder. The wind is due to the Bernoulli effect of it cresting over its rounded mass

[ötzi]

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.

[BmillsSkier]

Very cool. Thanks guys.

Apparently it’s so cold in NE that trees are just spontaneously exploding which is both very cool and terrifying

[ötzi]

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.

great science link, 'science world': https://www.sciencenatures.com/ for articles/posts on new science finding and discoveries, they dont put up new stuff as often as they used to but still very good.

Gordon Moore has died. RIP

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).
