Motion picture animation and video games are impressively lifelike nowadays, capturing a wisp of hair falling across a heroine’s eyes or a canvas sail snapping crisply in the wind. Collaborators from the University of California, Los Angeles (UCLA) and Carnegie Mellon University have adapted this sophisticated computer graphics technology to simulate the movements of soft, limbed robots for the first time.
Star Trek fans get hyped as scientists at NASA’s Johnson Space Center have just unveiled a design for a warp drive ship. NASA scientist and Advanced Propulsion Team Lead Harold White revealed that he was investigating if a warp drive ship could travel faster than light and if so, how can we build one.
In 1994, physicist Miguel Alcubierre proposed a method of warping space-time in his paper titled, “The Warp Drive: Hyper-Fast Travel Within General Relativity,” The idea is not to propel the ship faster than light, but to expand space time behind it, which subsequently would contract space time at the front of the ship. This decreases the time it takes to travel a distance enormously and the method is said to be valid within Einsten’s General Relativity.
CORONAVIRUS cases in Germany have almost trebled in the past 24 hours sparking fears of a second wave of COVID-19 infections.

Next-generation VTOL concepts are rising to meet the future needs of a modern-day battlefield.
Vertical take-off and landing (VTOL) concepts for unmanned aerial systems (UAS) certainly aren’t new. Their reconnaissance and intelligence-gathering roles date back to the 1950s, and there’s been a gradual path toward technological advancements in the decades since.
#Roobert33 In this experiment it’s noted that one half of an aluminum anodized copper globe is connected to an electrical wire in a DC current pole. At the center of the container there is an electrically isolated brass bolt from the container and connected to another pole of the DC current. At the base of the wooden support there is a large loudspeaker magnet that generates a magnetic attraction. Inside the container liquid mercury is poured in a weight of just over 1 Kg. When current flows through the two conductors, it generates a strong magnetic field that supports the system. This favorable condition rotates the liquid mercury as it’s an electric conductive metal. This experiment is known as the “Lorentz Force”. The operating voltage is 2V DC controlled by a DC inverter. The speed of rotation of mercury depends on the voltage being given. Increasing the tension the mercury takes off outside the bowl. *The system doesn’t work in alternating current. https://www.youtube.com/watch?v=au4hbUm4mMo

Anyons don’t fit into either of the two known particle kingdoms. To find them, physicists had to erase the third dimension.
A new VTOL capability for the Blackjack drone will scrap the launcher and make the system more expeditionary.
The French Armament General Directorate (DGA) announces that the Camcopter S100 VTOL UAV is now fully integrated with French Navy Mistral-class LHD Dixmude, stressing that for the first time in Europe, a rotary wing UAV is fully operational and connected to the combat system of a warship.
Researchers at the US Department of Energy (DOE)’s Oak Ridge National Laboratory (ORNL) are developing a nuclear reactor core using 3D printing.
As part of its Transformational Challenge Reactor (TCR) Demonstration Program, which aims to build an additively manufactured microreactor, ORNL has refined its design of the reactor core, while also scaling up the additive manufacturing process necessary to build it. Additionally, the researchers have established qualification methods to confirm the consistency and reliability of the 3D printed components used in creating the core.
“The nuclear industry is still constrained in thinking about the way we design, build and deploy nuclear energy technology,” comments ORNL Director Thomas Zacharia.
