Programmable liquid metal could bring the villain from Terminator 2 to life
Scientists are developing liquid metal or "electric blood" that can move and form 2D shapes. This may revolutionize the field of soft robotics.
U.K. researchers have developed a liquid metal that can move and even form 2D shapes. Remember the T-1000 from Terminator 2, one of the most badass villains ever to grace the big screen? It could someday walk the Earth. Not presently though. The U.K. model can’t make 3D shapes, yet. Such technology, however, is poised to revolutionize certain industries.
Researchers at the University of Sussex and Swansea University, both in the U.K., developed this programmable liquid metal. These scientists were able to form it into a variety of shapes including several letters of the alphabet and a heart. So how does it work? Using electrical fields controlled by a computer, scientists were able to shape the liquid or make it move. Yutaka Tokuda is a research associate who worked on the project. He said in a press release:
This is a new class of programmable materials in a liquid state which can dynamically transform from a simple droplet shape to many other complex geometry in a controllable manner. While this work is in its early stages, 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. The electric fields used to shape the liquid are created by a computer, meaning that the position and shape of the liquid metal can be programmed and controlled dynamically.
Step inside the unlikely friendship of a former ACLU president and an ultra-conservative Supreme Court Justice.
- Former president of the ACLU Nadine Strossen and Supreme Court Justice Antonin Scalia were unlikely friends. They debated each other at events all over the world, and because of that developed a deep and rewarding friendship – despite their immense differences.
- Scalia, a famous conservative, was invited to circles that were not his "home territory", such as the ACLU, to debate his views. Here, Strossen expresses her gratitude and respect for his commitment to the exchange of ideas.
- "It's really sad that people seem to think that if you disagree with somebody on some issues you can't be mutually respectful, you can't enjoy each other's company, you can't learn from each other and grow in yourself," says Strossen.

Learn how to redesign your job for maximum reward.
- Broaching the question "What is my purpose?" is daunting – it's a grandiose idea, but research can make it a little more approachable if work is where you find your meaning. It turns out you can redesign your job to have maximum purpose.
- There are 3 ways people find meaning at work, what Aaron Hurst calls the three elevations of impact. About a third of the population finds meaning at an individual level, from seeing the direct impact of their work on other people. Another third of people find their purpose at an organizational level. And the last third of people find meaning at a social level.
- "What's interesting about these three elevations of impact is they enable us to find meaning in any job if we approach it the right way. And it shows how accessible purpose can be when we take responsibility for it in our work," says Hurst.
Erik Verlinde has been compared to Einstein for completely rethinking the nature of gravity.
- The Dutch physicist Erik Verlinde's hypothesis describes gravity as an "emergent" force not fundamental.
- The scientist thinks his ideas describe the universe better than existing models, without resorting to "dark matter".
- While some question his previous papers, Verlinde is reworking his ideas as a full-fledged theory.
TuSimple, an autonomous trucking company, has also engaged in test programs with the United States Postal Service and Amazon.

- This week, UPS announced that it's working with autonomous trucking startup TuSimple on a pilot project to deliver cargo in Arizona using self-driving trucks.
- UPS has also acquired a minority stake in TuSimple.
- TuSimple hopes its trucks will be fully autonomous — without a human driver — by late 2020, though regulatory questions remain.
