A NASA rover streaked through the orange Martian sky and landed on the planet Thursday, accomplishing the riskiest step yet in an epic quest to bring back rocks that could answer whether life ever existed on Mars.

Researchers construct the smallest microchips yet using graphene nano-origami
Physicists from the University of Sussex have created what they called the tiniest microchips yet. The little microchips are made using graphene and other 2D materials and a form of “nano-origami.” The technique used in creating the tiny microchips marks the first time any researchers have been able to do this.
Researchers succeeded in making the tiny microchips by creating kinks in the structure of graphene to make the nanomaterial behave like a transistor. In their study, the team showed that when a graphene strip is crinkled in a specific way, it behaves like a microchip only about 100 times smaller than a conventional microchip. New construction methods are needed for microchips because traditional semiconducting technology is at the limit of what it can do.
The researchers believe that using the materials in their technique will make computer chips smaller and faster. The technology is dubbed “straintronics” and uses nanomaterials rather than electronics, allowing space for more chips inside a given device. The researchers believe everything we want to do with computers to speeding them up can be done by crinkling graphene.
Space Engine – the universe simulator
SpaceEngine is a realistic virtual Universe you can explore on your computer. You can travel from star to star, from galaxy to galaxy, landing on any planet, moon, or asteroid with the ability to explore its alien landscape. You can alter the speed of time and observe any celestial phenomena you please. All transitions are completely seamless, and this virtual universe has a size of billions of light-years across and contains trillions upon trillions of planetary systems. The procedural generation is based on real scientific knowledge, so SpaceEngine depicts the universe the way it is thought to be by modern science. Real celestial objects are also present if you want to visit them, including the planets and moons of our Solar system, thousands of nearby stars with newly discovered exoplanets, and thousands of galaxies that are currently known.


Native elders of the Arctic alert NASA – “Moon, Sun, and planet Earth are changing as we speak”
All of the Eskimos met at the Copenhagen Global Warming Summit and together they asked for NASA’s focus. In the end, they managed to get the publicity they wanted, and with it, they carried out a deadly premonition. They claimed that the atmospheric patterns of the earth are increasingly shifting, being changed by emissions to the extent where we’re not going to have much longer on this planet if we don’t change our way. The Sun is no longer rising from where it is meant to or so they say, and they state that the day no longer seems usual.

Supercomputer turns back cosmic clock
Astronomers have tested a method for reconstructing the state of the early universe by applying it to 4000 simulated universes using the ATERUI II supercomputer at the National Astronomical Observatory of Japan (NAOJ). They found that together with new observations, the method can set better constraints on inflation, one of the most enigmatic events in the history of the universe. The method can shorten the observation time required to distinguish between various inflation theories.
