The Earth’s Evaporating Aquifers — By Robinson Meyer | The Atlantic
Posted by Odette Bohr Dienel in category: water
“Many—if not most—of the Earth’s aquifers are in trouble. … That’s the finding of a group of NASA scientists, who published their study of global groundwater this week in the journal Water Resources Research. Water levels in 21 of the world’s 37 largest known aquifers, they report, are trending negative.”

“In Motion” Levitation Is Possible And No Longer Just a Myth — Eamon Kunze WT Vox
Posted by Seb in categories: anti-gravity, tractor beam
Levitation and the defiance of gravity is possible. If until now levitation was just a magic act or circus “reality” or, tractor beam technology existed just in sci-fi movies, recently, a team of Japanese researchers have demonstrated the first technology that not only brings the mythology of levitation to life but leap frogs it to create a tractor beam, lifting and moving objects across 3 dimensions using sound alone.
The essence of levitation technology is the countervailing of gravity. By stoping gravity, levitation is possible. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes. The acoustic axis of the ultrasound beam in conventional studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers.

The mTOR Story Part 1 — What Makes This Important Pro-Aging Molecule Active?
Posted by Maria Konovalenko in categories: biotech/medical, life extension
I have mentioned mTOR as one of the main aging genes on multiple occasions. It’s about time I tell you what it is, what it does and why it is so important in aging.
mTOR has a little m in front of TOR, which means I am speaking about mammals. It technically means «mechanistic» TOR, but think of it as the molecule that mice and all of us have, whereas in worms is it just TOR.
mTOR gene produces one mTOR protein that can act in two pretty different ways. mTOR does so, because it forms two complexes with other molecules. These complexes are called mTORC1 and mTORC2. Yeah, I know, it’s a lot of letters, but C1 and C2 stand for «complex 1» and «complex 2», so it kinda makes sense.

The Math That Shows Humans Could Live Ten Times Longer — Brian Merchant | Motherboard
Posted by Seb in categories: health, life extension
“When resources are scarce, a species as a whole has a better shot at surviving if its populations are organizing themselves to promote long term survival with shorter individual lifespans. They are evolving to combat overpopulation and overconsumption, basically…humans could be living a lot longer than they do now—we have, after all, inherited a lifespan from times when our forebears were eking out an existence as scrappy hunter gatherers” Read more

New Milky Way Galaxy Map Is The Most Accurate Ever Created By Jacqueline Howard | Huffington Post
Posted by Odette Bohr Dienel in categories: astronomy, science, space
“[W]ith the help of a new mapping method, scientists have created what they’re calling the most accurate map of the Milky Way. It confirms our galaxy is a four-armed spiral and shows in unprecedented detail a series of star clusters at the galaxy’s edge.”
