“Alien Invasion” −99% of the Microbes Inside the Human Body are Unknown to Science
Posted by Genevieve Klien in categories: biotech/medical, genetics, science
“There was something else, too – something weirder. Of all the non-human DNA fragments the team gathered, 99 percent of them failed to match anything in existing genetic databases the researchers examined. We found a whole new class of human-infecting ones that are closer to the animal class than to the previously known human ones, so quite divergent on the evolutionary scale.”
A landmark Stanford 2017 study indicates that more than 99 percent of the microbes inside us are unknown to science. The survey of DNA fragments circulating in the blood suggests the microbes living within us are vastly more diverse than previously known. In fact, 99 percent of that DNA has never been seen before.
A new survey of DNA fragments circulating in human blood suggests our bodies contain vastly more diverse microbes than anyone previously understood. What’s more, the overwhelming majority of those microbes have never been seen before, let alone classified and named, Stanford researchers reported in the Proceedings of the National Academy of Sciences.

The Wonders and Worries of ‘Extinct Animal’ Zoos
Posted by B.J. Murphy in categories: climatology, existential risks, sustainability
The future is both glorious and horrifying. As we continue to expand our technological footprint in the hopes of creating wonder, several issues remain fixed with a trajectory towards disaster. From climate change to the mass extinction of several animal species, there’s no doubt that we’re heading into ruin if we’re to keep this up.
As our technology continues to advance to the point of bringing the dead back to life, how will our own species react to a growing new population of animals that can die and live again?

This region runs ‘quality control’ for our brains
Posted by Genevieve Klien in category: neuroscience
Researchers have tended to overlook the cerebellum because of the difficulty in getting good scan data from the underside of the brain. That’s a mistake.

Your brain needs balance to pay attention
Posted by Genevieve Klien in category: neuroscience
When the brain gets ready to process something we see, some neurons prepare for work, while others remain in a resting state.

After states expanded Medicaid, fewer dialysis patients died
Posted by Genevieve Klien in category: biotech/medical
The adjusted absolute reduction in mortality in expansion states versus non-expansion states was 0.6 percentage points. Since end-stage renal disease affects more than 100,000 Americans each year, 0.6 percentage points equals hundreds of deaths annually, Trivedi says.
Better access to care
More research is necessary to determine exactly what caused the decrease in deaths, but the study suggests expanded insurance coverage, which provided better access to care, was the key factor in reducing mortality among this group. Medicaid expansion reduced the rate of end-stage renal disease patients without insurance by 4.2 percentage points, primarily through Medicaid coverage.

New light detector works a lot like gecko ears
Posted by Genevieve Klien in category: futurism
The way geckos’ ears work together to take in sound mirrors the way the detector works to map the angle of incoming light.

NASA: It was called “Little Joe,” because it was like rolling a two on each of the dice in a craps game
Posted by Genevieve Klien in categories: space, transportation
Four is the point Max Faget and Paul Pursur were trying to make in their quest to prove that harnessing that many modified Sergeant engines would make a $200,000 vehicle that would perform as well and with more flexibility, and would less cost than a $2.5 million Atlas or $1 million Redstone rocket.
Faget and Purser were two NASA space pioneers, whose aim was testing some of the Mercury components that would evolve into Apollo, including the escape and parachute systems and recovery methods, plus the performance of the space capsule under pressure at altitude.
Little Joe got off to an ignominious start when it blew its top one day at Wallops Island.
