Engineers Create the Blackest Material Yet (phys.org) 176

schwit1 writes: Researchers have created the least reflective material ever made, using as inspiration the scales on the all-white cyphochilus beetle. The result was an extremely tiny nanoparticle rod resting on an equally tiny nanoparticle sphere (30 nm diameter) which was able to absorb approximately 98 to 99 percent of the light in the spectrum between 400 and 1,400nm, which meant it was able to absorb approximately 26 percent more light than any other known material — and it does so from all angles and polarizations.

Only 8% of the Universe's Habitable Worlds Have Formed So Far (sciencemag.org) 140

sciencehabit writes: According to a new study, 92% of Earth-like planets haven't been born yet. Science reports: "Using data from the Hubble Space Telescope, researchers estimated the rates of past star and planet formation in the universe, which is now about 13.8 billion years old. They then combined that information with data from previous surveys that estimated the amounts of hydrogen and helium left over from the big bang that still haven't collapsed to form stars. At the time our solar system formed about 4.6 billion years ago, only about 39% of the hydrogen and helium in our galaxy had collapsed into clouds that then evolved into stars, they say. That means that the remaining 61% is available to form future solar systems that may include Earth-like planets in their habitable zones, the researchers report online today in Monthly Notices of the Royal Astronomical Society. In the universe as a whole, the researchers suggest, only 8% of its original starmaking gases was locked up in stars by Earth's first birthday. The rest will, over the remaining trillions of years of the universe's lifetime, coalesce into stars whose solar systems will contain a myriad of Earth-like planets."

Old eproms stored there data with a series of fuses. When first programming the chip fuses would be selectively burnt out to store the program data. A program that burnt out the remaining fuses would brick the chip. Modern eproms have limited read write cycles. A program that rewrote the chips over and over again could brick a chip in a matter of seconds.

We have had combine harvesters for the last 70 years that can replace hundreds of farm laborers. We have automated factorys that can run at night after we turn the lights out. Despite all of these advances we work longer hours than peasants in the middle ages, and longer hours than hunter gatherers. Something tells me that a magic replicator will not create a leasured utopia. We have had the technology for a leasured utopia since the industrial revolution and probably since the birth of agraculture. If you think technology will bring about post scarcity your a fool, we have had the technology for post scarcity for the last 80 years.

Why don't they just use a splashdown? It seems that corrosion resistance is relativly easier to solve than landing a rocket on a platform thats swaying in the ocean. You could even have it splashdown in a freshwater lake or a barge half filled with fresh water. You would also save the weight penalty of landing gear.

I don't know why they just don't land the thing in the water. It seems like waterproofing and preventing corrosion is a lot easier to solve than the controll problem of landing on a barge. Unlike landing on the moon, landing on a barge you have to deal with wind gusts, currents, and waves. A splashdown would leave a larger margin of error and neglect the need for landing gear.
