<p>Link to the original study below, free to access [0]. The key data appear to be this:<p>>At baseline, 184 (14%) of 1280 children with successful FEV1 measurement in London had a clinically low FEV1 (pre-bronchodilator FEV1 <80% of predicted value) compared with 126 (9%) of 1339 children in Luton (appendix p 8). At the end of the study, these values had dropped to 51 (9%) of 585 children in London and 41 (7%) of 606 children in Luton (appendix p 8).<p>So the proportion of children with low lung function dropped from 14% to 9% in London, and from 9% to 7% at the comparator site in Luton. It's not <i>that</i> much different, though any improvement is obviously welcome.<p><a href="https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(26)00163-5/fulltext" rel="nofollow">https://www.thelancet.com/journals/lanpub/article/PIIS2468-2...</a></p>

<p>That's the source of emission by the cow or steer. Industrial processing of the dung produces vastly more.<p>Table 3 in this source [0] shows enteric vs manure methane emissions are 158 vs 137 kg CH4/yr for dairy cows, who are mostly fed in feedlots, and 58 vs 2.4 for meat and other cattle, in the US and Canada. So the CH4 emissions range 65-fold from 2.4 to 158 depending on how the cattle are farmed.<p>[0] Revised methane emissions factors and spatially distributed annual carbon fluxes for global livestock.  <a href="https://pmc.ncbi.nlm.nih.gov/articles/pmid/28959823/" rel="nofollow">https://pmc.ncbi.nlm.nih.gov/articles/pmid/28959823/</a></p>

<p>Animal-emitted CO2 isn't the problem, but methane.<p>The CO2 captured by plants and eaten by livestock gets converted in part to methane, a more more potent greenhouse gas. This does eventually degrade back to the original CO2, but on a scale of decades, it's currently too slow to prevent accumulation of methane.</p>

<p>Stockyards are the worst offenders. This is due to how the dung is processed, which releases a lot of methane. Grass-fed cattle have much lower net emissions of greenhouse gasses.</p>

<p>It isn't the "cow farts" that produce most methane, but rather the anaerobic processing of cow dung emanating from feed lots, dairy operations, etc.<p>Grass-fed beef cattle whose dung is "recycled" in a more natural way in the fields produce the same emissions as would wild ruminants such as antelope, bison, etc.<p>The biodiversity problem in the above refers mostly to new land clearances intended for farming, including for feedstock. This is minor in N. America and Europe, mostly as the clearances were done decades or over a century ago.</p>

<p>Agreed. The audience here tends towards functional/technical writing rather than expressive writing.<p>On the other hand, should an article about typography be posted, then there will be many comments regarding the nuances of serifs, kerning, spacing and ligatures. Ignoring of course that none of these change the facts/data being communicated!</p>

<p>Browsing that site, The SETI Institute appears to have expanded beyond its original goal of finding extraterrestrial intelligence into astrobiology and more. Perhaps the first attempts at detecting alien radio signals hoped too much?<p>I have little doubt that, given the infinite size of the universe, that extraterrestrial intelligence (of some sort) exists, the question is whether we will ever detect it... It perhaps even exists as close to us as Europa, should we attempt a landing there...</p>

<p>>I can't imagine that the same factors aren't at play in the scientific research community<p>I can't speak for the entire scientific research community, but I can say that for basic biomedical research (not clinical research), LLMs are mostly ignored. They simply don't have the ability to parse most raw wet lab data.<p>This obviously has not stopped the creation of a legion of startups, new Asst Profs, etc, claiming that they are using "AI" to crack new frontiers. In practice, the most effective of these use machine learning, rather than LLMs.</p>

<p>>“We can do neuroscience on A.I. systems in a way that we kind of can’t with humans,” Mr. Long said, in that they “don’t have skulls.” The three jobs Eleos was hiring for would all be machine-learning research scientists who could design and perform experiments.<p>This is pretty interesting! I wouldn't know how easy such "surgery" on LLMs would be to do, if if they do have "knowledge" or "consciousness" as their proponents claim, there could be some profound outcomes from this.</p>

<p>You will notice that the criticism this judgement receives if not for finding Song guilty, even if the sentence is inordinately long for a non-lethal crime with minor wider repercussions.<p>The criticism this judgement receives is the fact that the prosecutors and judge drew these lines of association into a "terrorist organization" so much that even merely possessing literature tangentially related to this non-existent "organization" was deemed a crime worthy of 30 years imprisonment. This is the sort of thinking that sent people to the Soviet Gulags.</p>
