Reply to AskScience AMA Series: I'm Birgül Akolpoglu, a doctoral researcher at the Max Planck Institute for Intelligent Systems in Germany. I work on microalgae and bacteria-based microrobots that could one day be used to deliver drugs and battle cancer! AMA! by AskScienceModerator
It appears that the U.S. CIA has been making contributions to universities for the study of extremophiles. Do you know wgat the use-case would be for them? They are at such depths and pressures that they might be a stepping stone organusm to study. If ghey could be coaxed to work in a more moderate context , then they might be able to assist in processing magnesium, iron, or rare earth minerals.

There are a couple of shops in Waltham. Food overlaps with Guate pepian foods.

And dodos don't have teeth as a DNA source.

Reply to comment by TownAfterTown in Would it be possible to calculate the total (historical) carbon footprint of a big festival, like Glastonbury? by AllThingsAreReady
Yes, it's a complex Fermi question. The most productive approach would be in using hedonic analysis to reduce the number of variables. https://corporatefinanceinstitute.com/resources/knowledge/other/hedonic-regression-method/

Reply to Is there an effect that is analogous to mechanical cavitation for electrical waves? by Sittes
One effect that is interesting is the precession of organic (kerosene) molecules in a proton procession magnetometer. Ever time a square wave cycle is imposed on the hydrocarbon using a wrapping coil the protons align the the coil. When the square wave amplitude drops to zero the protons return to align with the Earth's magnetic field. But they don't snap back immediately because they are spinning. Instead they proceed back, and the precession can be read on the same coil as an imposed decaying sine wave. The stronger the Earth's field, the faster the precession takes place. Using a crystal oscillator as a reference the Earth's field can be read to 1 part in 50,000 (lambdas). Submarines sometimes use these measurements of known magnetic fields to navigate through undersea mountain ranges.

The costal areas along Vietnam has much lower salinity due to the Monsoon rains. The corals don't like that so they disappesf. No corals, no fish. The coasts are mostly barren sand. Harvard is looking in to low-salinity corals, but it's still early in that research. Tuburtity is also a concern because the silica cuts the fishes gills.

That's just salt that came through a faulty wirmhole.
