This could lead to artificial gravity like we see on star trek.
Many physicists said that gravitons exist but some believe that it is impossible to observe it in the natural world. Recent studies suggest that gravitons create ‘noise’ making them easier to spot.

LEDs have come a long ways. From the early 70s when a bulky LED watch cost thousands of dollars to LG’s announcement last month that it had created an OLED TV as thin as a magazine, these glowing little bits of magic have become wonderfully cheap and impossibly small. But guess what: they’re about to get much smaller.
A team scientists from the University of Washington just built the world’s thinnest possible LED for use as a light source in electronics. It’s just three atoms thick. No, not three millimeters. Not three nanometers. Three atoms.
“These are 10,000 times smaller than the thickness of a human hair, yet the light they emit can be seen by standard measurement equipment,” said Jason Ross, a UW materials scientist and graduate student who helped with the research. “This is a huge leap of miniaturization of technology, and because it’s a semiconductor, you can do almost everything with it that is possible with existing, three-dimensional silicon technologies.”

Ira Pastor, ideaXme life sciences ambassador interviews Craig Fugate Chief Emergency Management Officer of One Concern and former administrator of the Federal Emergency Management Agency (FEMA).
The international context of this interview: In choosing our leaders it is becoming increasingly important to select people who can both anticipate and address and where possible avoid large scale disasters. Here, Craig Fugate discusses evaluating past disasters, planning for future events and reacting to the “unexpected” — “think big and move fast”.

SpaceX is preparing to conduct a national security mission for the United States Space Force. The aerospace company is tasked to deploy the military’s fourth new-generation series Global Positioning System satellite, known as GPS-III Space Vehicle 04. On October 2nd, SpaceX attempted to launch the satellite to orbit but at around two seconds before the 9:43 p.m. EDT liftoff time, launch controllers aborted the launch at Cape Canaveral Air Force Station’s Launch Complex 40.
During the Live broadcast of the launch attempt the Principal Integration Engineer at SpaceX John Insprucker said the next launch opportunity for this mission is on Saturday, October 3rd at 9:39 p.m. EDT. but the rocket did not attempt a second launch because SpaceX found issues on one of the Falcon 9 rocket’s nine Merlin 1D engines. According to SpaceX founder and Chief Executive Officer Elon Musk, the Falcon 9 rocket carrying the GPS-III satellite experienced an “unexpected pressure rise in the turbomachinery gas generator,” he wrote. “… We’re doing a broad review of launch site, propulsion, structures, avionics, range & regulatory constraints this weekend. I will also be at the Cape next week to review hardware in person,” he said early October.
SpaceX’s Vice President of build and flight reliability, Hans Koenigsmann, said during a news conference on October 28th that SpaceX engineers worked alongside the U.S. Space Force and NASA to perform a deep investigation into the issue. They came to the conclusion that the Falcon 9 engine issue was due to a residue of a “masking lacquer” designed to protect sensitive parts during anti-corrosion anodizing treatment. Koenigsmann told reporters the SpaceX vendor that performed the lacquer coating treatment failed to remove all of the lacquer afterward, causing a blockage of small vent holes for Merlin engine valves. “It’s not necessarily bad,” he said, “In most cases, it rattles the engine, and it may cause a little bit of damage to the engine. In extreme cases, it may cause more damage to the engine.” SpaceX officials announced they would fix the issue by replacing the engine. Now, SpaceX targets to deploy GPS-III Space Vehicle 04 satellite atop the Falcon 9 no earlier than Thursday, November 5th at 6:24 p.m. EDT [date is subject to change]. This mission is important for the United States because the GPS-III satellite is designed to upgrade the satellite constellation that actively provides navigation services to over 4 billion users.
As progress in traditional computing slows, new forms of computing are coming to the forefront. At Penn State, a team of engineers is attempting to pioneer a type of computing that mimics the efficiency of the brain’s neural networks while exploiting the brain’s analog nature.
Modern computing is digital, made up of two states, on-off or one and zero. An analog computer, like the brain, has many possible states. It is the difference between flipping a light switch on or off and turning a dimmer switch to varying amounts of lighting.
Neuromorphic or brain-inspired computing has been studied for more than 40 years, according to Saptarshi Das, the team leader and Penn State assistant professor of engineering science and mechanics. What’s new is that as the limits of digital computing have been reached, the need for high-speed image processing, for instance for self-driving cars, has grown. The rise of big data, which requires types of pattern recognition for which the brain architecture is particularly well suited, is another driver in the pursuit of neuromorphic computing.
Virgin Hyperloop, the transportation company owned by business magnate Richard Branson, has ambitious plans to build a vacuum tube transportation system that travels over 600 miles per hour.
But before it does so, the company has made the reasonable decision to figure out what traveling that quickly might to do the brain. To wit, scientists at West Virginia’s Rockefeller Neurosciences Institute (RNI) will find out what to expect when launching passengers at 78 percent the speed of sound.
Hold on to your brains!
This is the episode for anyone who has wondered about the fundamental structure of the universe and its extremely distant future — a time which is so distant that for all practical purposes, it’s almost synonymous with eternity. Black Holes, Fundamental Physics, and the meaning behind the cosmological catchphrase — Turtles All the Way Down. Please listen.
What happens when all the stars in our cosmos’ galaxies burn out; with little or no hydrogen gas left to fuel star formation; and everything pretty much turns to toast? It will presage an age of black holes where extremely low temperatures and fundamental particle decay will alleviate life as we know it. This universal endgame in an almost infinite far future may actually be a Dark Age where little or nothing can happen. And if it does, only on the longest timescales. Yale University astrophysicist Gregory Laughlin and I discuss these and other issues in this cosmological “turtles all the way down” episode of the podcast.
Space — The final frontier, and for Soviet cosmonaut, Sergei Krikalev, it nearly was his final frontier! Check out today’s new video where a soviet astronaut was on a space mission, meanwhile the USSR crumbled,… More making him the last citizen of the Soviet Union. How did Sergei finally get home, and what home would he be coming back to? Check out this epic new space story to find out!
