SF startup Navier hopes to disrupt transportation with futuristic water taxis that would cruise on the bay. A possible alternative to BART, ferries and traffic.
The machine, which weighs only 22 lb (10 kg), is a single-piston-linear-engine, that runs exclusively on hydrogen. As it has only 20 components and one moving part, the engine is also much cheaper to produce and maintain than traditional engines.
Cryonicists hope that modern technology will one day bring frozen bodies back from the dead. But how realistic is a second life after a deep freeze?
A few hours ago, the Fuego volcano erupted in Guatemala.
An orange alert has been declared.
The eruption resulted in the formation of ash columns over 5 km high.
Lava flows began to descend from the crater.
Abundant volcanic ash fell on nearby villages.
The evacuation of residents and the blocking of roads begins.
It is expected that the activity of the volcano will continue for at least another 24 hours.
Fuego is one of the most active volcanoes in the country.
It is located 40 km from the capital of Guatemala.

All that glitters isn’t usually gold, and the same is true for 183 million-year-old fossils found in the Posidonia Shale. Moreover, while the researchers used to think the shiny gold coating on the fossils was fool’s gold, new research has revealed a more surprising answer.
The Posidonia Shale in southwest Germany is the source of many of these golden-hued fossils, particularly those of soft-bodied sea life such as squid and ichthyosaur embryos that were around in the early Jurassic. These geological deposits containing soft-bodied preserves are known as Konservat-Lagerstätten and are extremely rare.
Previously it was thought that anoxic conditions helped to fossilize these specimens. While pyrite, also known as fool’s gold, was thought to be the source of this shine, a closer inspection has revealed more about the conditions in which these fossils were formed.
After decades of frustration, researchers have finally determined how an airborne scent molecule links to a human smell receptor.
