Liquid Metal Brings Soft Robotics One Step Closer to Terminator 2

In 1991, Terminator 2 introduced us to a “soft” robot made from then-futuristic shape-shifting technology arrived from the future — seemingly impervious to all weapons.
The special effects were stunning; the morphing metal shone like chrome and flowed like water. Bullets passed through the self-healing material as if it were butter.
Fast-forward to March 2018. Researchers at the University of Sussex in England have applied electrical charges to “liquid metal” allowing them to manipulate the material into 2-D shapes — so far, simple numbers and letters.
A computer controls the electrical activity so that the metal is programmable and dynamic. Simple, but with far-reaching implications for the soft robotics field.
Professor Sriram Subramanian, project head, said,“Liquid metal technologies are an extremely promising class of materials for deformable applications. One of our long-term visions is a programmable liquid metal that changes the physical shape, appearance and functionality of any object through digital control to create intelligent, dexterous and useful objects that exceed the functionality of any current display or robot.”
While a liquid metal terminator androids are a good ways off, researchers are considering possibilities like re-programmable circuit boards and conductive ink.
“The compelling evidence of detailed 2D control of liquid metals excites us to explore more potential applications in computer graphics, smart electronics, soft robotics and flexible displays,” said Research Associate Yutaka Tokuda.
Government Admits Oumuamua Wasn't First Interstellar Object

The U.S. military confirmed the first interstellar object to hit Earth was years before Oumuamua and corroborates research done by a famous astronomer.
We’ve reported before about Oumuamua, the first interstellar object to enter our solar system in 2017, and Harvard professor Avi Loeb’s book arguing Oumuamua might be extraterrestrial. Whatever it was, its existence was remarkable as the first interstellar object to enter our solar system.
But now, we are learning that Oumuamua was the second interstellar object to enter our solar system, and this discovery was made by none other than Avi Loeb.
In 2019, Loeb, working with his student Amir Siraj, combed through the database of meteors looking for other interstellar objects. When they found evidence of a fast-moving meteor that hit the Earth, they wrote a paper arguing it was interstellar too and preceded Oumuamua by almost four years.
“The referees of the paper that we wrote rejected the paper, and argued that it should not be published,” Loeb said. “Because they don’t trust the government and perhaps the uncertainties that are often quantified in the scientific literature as ‘error bars,’ which they are just the level of uncertainty in the measurements (that) are unknown.”
