New Deep #Sea Creatures ‘Challenge Current Models of Life’
#Scientists have discovered #chemosynthetic #animals, which don’t rely on Sun to live, nearly 6mi under the #ocean surface—deeper than any found to date.
Chemicals like #methane and #hydrogensulfide leak out of so-called “seeps” in these active zones, which can be metabolized by chemosynthetic microbes that form the basis of diverse #ecosystems that live completely off the bio-solar grid.

#NaturalGas is composed mostly of #climate-warming #methane but also contains other gases such as #HydrogenSulfide, which is #deadly at high concentrations. #Gas escapes as wells are drilled & before infrastructure is in place to capture it. It also can be intentionally released if pressure in the system poses a safety risk or if capturing & transporting it to be sold is not profitable.

[I have long been fascinated by this ‘accidental waterbody’, from its creation all the way through the extreme pollution issues as it evaporates – and the lithium under it – a heck of a history, culturally, demographically, hydrologically, contaminants, public health, agriculturally and so much more…]

The reason I'm wondering about hydrogen sulfide is because it induces torpor.
I did some searching and found a study suggesting similarities between H2S and donepezil -"Exogenous H2S up-regulates the expression of ADAM10 and ADAM17 and sAPPα, and effectively reduce the production of Aβ40, Aβ42 and sAPPβ in vitro in PC12. The PI3-K or JNK signal pathway may be involved in the regulation. Donepezil has similar effects as H2S, which involves PI3-K, JNK or p38 MAPK signaling."
https://doi.org/10.1016/j.niox.2012.08.012So now I'm wondering why donepezil isn't disease modifying in Alzheimer's. However, I found this -
Donepezil delays progression to AD in MCI subjects with depressive symptoms

.@sonal_nd @ShouGroup &co show that a novel #sulfide assimilation pathway involving HSU1 allows the #yeast MET17 auxotroph to overcome its metabolic defect, but only at high cell densities when #HydrogenSulfide gas can accumulate #PLOSBiology https://plos.io/4aekoGa

Thiol reductive stress activates the hypoxia response pathway
Unbiased genetic screens by Jogender Singh and coworkers at IISER Mohali show that #thiol #antioxidant #DTT affects not only the ER, but also leads to #hydrogensulfide production and #hypoxia responses

Meet the #sargassum belt, a 5,000-mile-long snake of #seaweed circling #Florida
Key points:
- Sargassum can contain heavy metals, including arsenic. It has fairly high concentrations of the toxin, that, through leaching, that could impact groundwater.
- Humans are altering the nitrogen cycle. We're using more fertilizer, burning biomass, cutting down forests and increasing wastewater from cities, all of which sends ammonium, nitrate and phosphate down major river systems

"In the open sea, healthy patches of sargassum can soak up carbon dioxide and serve as a critical habitat for fish, crabs, shrimp, turtles and birds.
"But if sargassum moves closer to the coast, the #seaweed can wreak havoc on local #ecosystems, smothering #coral reefs and altering the water's pH balance. Once ashore, clumps of sargassum can choke local economies by closing tourism sites, cutting off marinas and constricting fishing yields.
"Sargassum begins to rot after about 48 hours on land, releasing irritants like #hydrogensulfide, a hazard to anyone with respiratory issues like asthma. Oh, and the resulting smell resembles manure or rotten eggs — not a great spring break aroma.
"It used to be that sargassum rafts were disparate, sporadic bodies, causing little disruption to beach-going.
"But scientists noticed a change in sargassum levels in 2011, when masses of the seaweed multiplied, gaining in density and size, becoming so big they were captured on satellite images.
"Today, the patches comprise a 5,500-mile-long, 10 million-ton belt that circulates annually, starting near West Africa and snaking through the Gulf of Mexico back into the Atlantic."
