Then, after a series of defeats in Egypt, Napoleon returned to France in 1799 and left many of the scientists stranded. At the time of Napoleon's invasion, travelers had long known of Alexandria, Cairo, and other parts of Lower Egypt. Just 21 and a botanist by training when he arrived in Egypt, Savigny collected invertebrates like worms, bees, spiders, snails, and flies. The Rosetta Stone helped Champollion discover how to decipher hieroglyphsFor centuries, no one could read hieroglyphs, the pictorial writing that covered many Egyptian monuments. When the French found the Rosetta Stone during their invasion, they knew it could serve as a kind of translation key.

REUTERS/Amr Abdallah DalshSAQQARA, Egypt, May 27 (Reuters) - Egypt unearthed human and animal mummification workshops as well as two tombs in the ancient burial ground of Saqqara, officials said on Saturday, marking the latest in a string of discoveries that the country hopes can help revive its vital tourism industry. Mostafa Waziri, the head of Egypt's Supreme Council of Antiquities, told reporters that the two large "embalming workshops" date back to the 30th dynasty (380-343 BC) and the Ptolemaic (305-30 BC) eras. "We found embalming workshops, one for humans and one for animals. We found all the tools that they used (in mummification) in ancient times," Waziri said. Both workshops featured stone beds, clay pots, ritual vessels, natron salt, which is one of the main ingredients for mummification, and linens among other mummification instruments.
Sodium-ion batteries have been around for decades, but large-scale development of the technology was abandoned in favor of lithium-ion batteries. Sodium-ion batteries can't provide the type of range for electric vehicles offered by lithium-ion batteries, but they do present some unique advantages. For instance, the materials used in sodium-ion batteries tend to be cheaper than those in lithium-ion batteries. "There's no cobalt, there's no copper, there's no lithium, there's no graphite, which is really primarily controlled by China today." Natron Energy, based in Silicon Valley, is also working to commercialize sodium-ion battery technology.

CNBC spoke to two such companies, Natron Energy and Faradion, that are looking to commercialize the technology.
