Something both the #Hopi and #Romans (and other cultures) shared -- using plant-based ashes in food and medicine!
#GladiatorGatorade? Ancient Athletes Had A Recovery Drink, Too
by Maria Godoy, October 27, 2014
Excerpt: "#PlantAshes were evidently consumed to fortify the body after physical exertion, and to promote better bone healing,' Fabian Kanz, a forensic anthropologist at the Medical University of Vienna who led the research, said in a statement. 'Things were similar then to what we do today."
"Evidence for this ancient dietary supplement comes from a second-century cemetery for gladiators in what was once the great Roman city of Ephesus, in modern-day Turkey. Kanz and his colleagues have been studying the remains buried there to unravel how these athletes lived. To figure out what they ate, the researchers examined the remains of 22 gladiators using stable carbon and nitrogen isotope ratio analysis.
"Carbon can tell us about the plants these people ate, while nitrogen offers hints of their animal protein consumption. The gladiators were eating a pretty varied diet, the analysis showed. Some went heavier on the #grains and #greens; some ate more meat.
"When the same tests were run on the remains of 31 regular folks from that era and region, they found the same sorts of variation. In other words, gladiators seemed to be eating the same way as everyone else.
"But the researchers also decided to look at the trace elements of strontium and calcium in those old bones. And that's where a huge difference jumped out. Compared with the regular Joes, the gladiators had a much larger ratio of strontium to calcium.
" 'This is strong evidence that the gladiators were consuming something high in calcium to replenish their calcium stores that other people weren't and that didn't show up in the isotopes,' says Kristina Killgrove, a biological anthropologist at the University of West Florida who studies imperial Rome through ancient bones.
"The researchers wondered: If the gladiators weren't eating more meat than their contemporaries, then where was this calcium boost coming from? A nearly 2,000-year-old encyclopedia offered a tantalizing clue.
"In his #NaturalisHistoria, published in the first century, #PlinyTheElder wrote: 'Your #hearth should be your #MedicineChest. Drink #lye made from its ashes, and you will be cured. One can see how gladiators after a combat are helped by drinking this.'
"Using ash in food and medicine wasn't limited to the Romans. The #Hopis used ash from burned plant leaves and pea pods to prepare #BlueCornmeal foods like #PikiBread and #BivilvikiDumplings. The ash provided essential elements like #calcium, #manganese, #copper and #iron."

#SodiumIonBatteries offer an alternative to tricky #lithium
Oct 26th 2023
Excerpt: "Fortunately, lithium is not the only game in town. As we report this week, a clutch of firms are making batteries based on sodium, lithium’s elemental cousin. Since sodium’s chemical properties are very similar to those of lithium, it too makes for good batteries. And sodium, which is found in the salt in #seawater, is thousands of times more abundant on Earth than lithium and cheaper to get at. Most of the companies using sodium to make batteries today are also Chinese. But pursuing the technology in the West might be a surer route to energy security than relying heavily on lithium.
"Besides its abundance, sodium has other advantages. The best lithium batteries use #cobalt and #nickel in their electrodes. Nickel, like lithium, is in short supply. #Mining it on land is #EnvironmentallyDestructive. Proposals to grab it from the #seabed instead have caused rows. A good deal of the world’s cobalt, meanwhile, is extracted from small mines in the #DemocraticRepublicOfCongo, where #ChildLabour is common and working conditions are dire. Sodium batteries, by contrast, can use #electrodes built from #iron and #manganese [and wood #lignin], which are plentiful and uncontroversial. Since the chemical components are cheap, a scaled-up industry should be able to produce batteries that cost less than their lithium counterparts.
"Sodium is not a perfect replacement for lithium. It is heavier, meaning sodium batteries will weigh more than lithium ones of an equivalent capacity. That is likely to rule them out in some cases where lightness is paramount. But for other applications, such as #GridStorage or #HomeBatteries, weight is irrelevant. Several Chinese carmakers are even beginning to put sodium batteries in #ElectricVehicles."

As #Norway Considers #DeepSeaMining, a Rich History of Ocean Conservation Decisions May Inform How the Country Acts
In the past, scientists, industry and government have worked together in surprising, tense and fruitful ways
by Christian Elliott, April 21, 2025
"At the #Arctic #MidOceanRidge off the Norwegian coast, molten rock rises from deep within the Earth between spreading tectonic plates. Black smoker vents sustain unique ecosystems in the dark. Endemic species of long, segmented bristle worms and tiny crustaceans graze on bacteria mats and flit among fields of chemosynthetic tube worms, growing thick as grass. Dense banks of sponges cling to the summits and slopes of underwater mountains. And among all this life, minerals build up slowly over millennia in the form of #sulfide deposits and #manganese crusts.
"Those minerals are the kind needed to fuel the global green energy transition—#copper, #zinc and #cobalt. In January 2024, Norway surprised the world with the announcement it planned to open its waters for exploratory deep-sea mining, the first nation to do so. If all went to plan, companies would be issued licenses to begin identifying mineral deposits as soon as #Spring2025. To some scientists who’d spent decades mapping and studying the geology and ecology of the Norwegian seabed and Arctic Mid-Ocean Ridge, the decision seemed premature—they still lacked critical data on the area targeted for mining. The government’s own Institute of Marine Research (IMR) accused it of extrapolating from a small area where data has already been collected to the much larger zone now targeted
“ 'Our advice has been we don’t have enough knowledge,' says Rebecca Ross, an #ecologist at IMR who works on Norway’s #Mareano deep-sea mapping initiative. She says the decision was based solely on the #geology of the area. Taking high-resolution scans of the seabed and sampling its geology is the first step when research ships enter a new area, but critical biological and ecological research is more difficult and tends to come later—which is the case on the ridge area targeted for mining. Ross says it’s certain that area contains vulnerable marine ecosystems that would be affected by the light and noise pollution and sediment plumes generated by mining. The IMR estimates closing the knowledge gap on the target area could take ten years.
"The same conflict, with a partial scientific understanding misinterpreted and used to justify resource extraction, is playing out in the #Pacific, where mining pilot projects are already underway in international waters. Years before, scientists funded by industry scouted the #seabed there, discovering both valuable minerals and new forms of life."
