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."

🦂🧪 #Scorpions incorporate #metals like #zinc and #manganese into the tips of their stingers and the edges of their pincers.

This #biomineralization process makes their #anatomy more resistant to wear and breakage during #hunting. Scientists found that the specific placement of these #minerals depends on the physical needs of different scorpion species.

#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."
