Startship controlled by a 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.

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.

“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
