K2-141b. “Oceans Of Molten Lava And ‘Rocky Rain’ On The Most Extreme Planet Yet. It’s thought that K2-141b is a place where rock is vaporized and falls as a mineral “rocky rain” that replenishes an ocean of molten lava, and supersonic winds that rage over 3,100 mph/5,000 kmph. However, it’s those high temperatures on its day-side that create something bizarre; a cycle something like Earth’s water cycle, but with rock. It’s so hot that rock is thought to evaporate and precipitate. In short, it rains rock.” https://www.forbes.com/sites/jamiecartereurope/2020/11/06/weve-found-oceans-of-molten-lava-and-rocky-rain-on-the-most-extreme-planet-yet-say-scientists/?sh=573707fa4825 View in LinkedIn

JUST STAMP COLLECTING is a criticism that can be leveled at the descriptive nature of astronomy, which is accumulating basic information with spanking new tools in the absence of grand schemes and broad theories. This criticism has been leveled at biology for the same reasons. But it is a natural developmental stage of a data heavy science. With this in mind, we will look at a range of extreme planets and stars. View in LinkedIn

THE UNCERTAINTY PRINCIPLE. “Suppose you have an ice bucket containing H2O. You don't know whether the water is in the form of liquid or ice cubes, and you're not allowed to look into the bucket. So you try an experiment to find out. You grab a pair of tongs and stick them into the bucket, and out come ice cubes. But if you dip in a ladle, you get liquid water.” https://lnkd.in/g-p9M-4 View in LinkedIn

WASP-121b. Nine-hundred light-years from Earth, there's a football-shaped planet so hot that heavy metals boil through its atmosphere, venting into space. The planet is about 10 times hotter than any other known exoplanet, due to its proximity to its host star, which is hotter than the sun. This proximity also gives the planet its unique shape, because gravitational tidal forces in its atmosphere elongate the whole planet.” https://lnkd.in/d3b5Rts View in LinkedIn

WASP-189b temperatures “are enough to melt all rocks and metals, and even turn them into a gaseous form. It is not quite as hot as the surface of our Sun (6,000 degrees Celsius or 10,832 degrees Fahrenheit), it's basically as toasty as some small dwarf stars.” https://lnkd.in/dyZ3niw View in LinkedIn

CYBERNETICS. “The essence of computational science is the capacity to engineer circuits that transform information from one form into another on the basis of a set of rules. How might the lessons learned here apply to biology? Evolution selects those members of a genetically diverse population whose descendants proliferate rapidly and survive over many generations.” https://www.nature.com/articles/35011540 View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and ends this weekend on the theme of modular metabolism. The realization that many systems in biology are modular is relatively recent. Somewhere between computer programming and engineering the ideas of modular efficiencies seeped into biology, and their impact has been powerful. Nature benefits from modular design because living structures are the most complex structures in the universe, and any pathway that can make their construction — and inevitable modification during development or evolution — less difficult is an obvious energetic advantage.

MORE ENGINEERING DEVICES. “Coincidence detection systems require two or more events to occur simultaneously in order to activate an output. Amplifiers are built to minimize noise relative to signal, for instance by choosing appropriate time constants for the circuits. Parallel circuits (fail-safe systems) allow an electronic device to survive failures in one of the circuits.” https://www.nature.com/articles/35011540 View in LinkedIn
