Hat tip - this deserves some io9 followup, in addition to the sweet potatoes!
i’ve been meaning to check this out! thanks!
totally. i’m still musing writing an article about sweet potatoes, all of which (edible varieties) were naturally transformed by agrobacterium sometime in their history. aka natural gmos containing foreign DNA. :)
Rennet enzymes are naturally made by calf stomach cells, not bacteria, though there’s guaranteed to be microbes, and microbial enzymes, in such rennet. FPC, on the other hand, is made of the pure calf chymosin enzyme.
awesome link, thank you! (that’s why i called the nomad story “popular legend”... :) )
it’s worth noting that the prof featured in that article fails to address how rennet came into use. not that the nomad legend has any evidence to back it up. but it would great to discover how rennet became the go-to milk coagulating… Read more
impressive! the yields do vary. i think i gleaned 20k from stats in the US taken from 2003-2007. i also read that the record is about 50,000lbs in one year. inbreeding can do wonders, eh?
i also had a ‘no matter how you slice it’ in the first draft :P
If you’re interested, I wrote this article last year to explain the science of GMOs. There’s a nifty timeline of genetic engineering as well as an infographic comparing different methods of genetic modification, including the kind that occurs in nature. Tl;dr: transforming bacteria or fungi with a plasmid (circular… Read more
AFAIK, the “90%” stat reflects the volume of the largely hidden iceberg that is budget/fast-food/industrial cheese consumption, and not cheese-lover consumption. If you go to a cheese specialty shop, or even a cheese counter in places like Whole Foods (or, my favorite, Berkeley Bowl here in California), you’ll… Read more
This is a key question. Like ScienceGal said, the short answer is yes. But w/regard to this study, there are a few details worth mentioning.
In this study, the authors were able to definitively characterize these structures as lymphatic vessels but only in mice - they used a variety of techniques to show that the… Read more
Rarely doesn’t mean never, but nuance was never a forte of the anti-GMO movement :)
Yup! Genes function in the context of the chromosomes on which they reside, which is why looking at gene sequence alone isn’t enough to explain many biological phenomena. I don’t think it would be wrong to say that “chromosome architecture” encompasses both the location of genes on chromosomes, and those genes’… Read more
Beta testing indeed! I wonder when we’ll find the next muntjac.
I do (deeply) regret using that phrase but that's about it. As a neuroscientist I think it is important to remind people that these drugs affect the brain in identical ways to certain street drugs. The idea that we shouldn't criticize biological psychiatry for fear it will push people away from it is ludicrous;… Read more
imipramine was the first TCA, iproniazid the first MAOI. i would guess most doctors have their patients’ best interests in mind when prescribing these drugs, but it’s too bad that results in so many patients getting scrips for these drugs with nary a follow-up (http://www.cdc.gov/nchs/data/data…). i have a hard time… Read more
This is an honest question: in the original version, where did I ever make that overstatement? The article is about the chemical imbalance theory. Psychiatrists who convince patients to take drugs using science that doesn’t exist are toeing an ethical line - up to you to judge whether a white lie is acceptable in… Read more
Should I refrain from criticizing prescription of a drug simply because someone benefits from it? Two sides to the coin of drugs in psychiatry. Look around - people for whom anti depressants failed are happy with my piece, people who rely on those drugs are offended. Which is strange considering how I acknowledge both… Read more
i think articles that delve so deeply into history and science tend to be too long for internet-swamped attention spans, unfortunately.
