Autonomous food delivery company Starship Technologies hit 1 million deliveries this month, and has doubled the size of its robot fleet.


Starship Technologies, the autonomous delivery company that sends little six-wheeled robots to people’s doorsteps with groceries and takeout, has had an astonishing year.

Many believe that drug companies should already be updating their vaccines to target mutated versions of the Covid-19 spike protein. But can the patterns of mutations scientists are seeing popping up in Covid-19 around the world offer any clues about how the virus will continue to evolve?

“It is hard to speculate, but it is interesting that all of a sudden there does seem to be a lot of mutations appearing that could be associated with immune escape or immune recognition,” says Brendan Larsen, a PhD student working with Worobey in Arizona. He recently identified a new variant of Covid-19 circulating in Arizona that has the H69/V70 deletion seen in several other versions of the virus. While still only spreading at a relatively low level there and in other states of the US, it suggests that this particular mutation is recurring independently around the world.


Every time the coronavirus passes from person to person it picks up tiny changes to its genetic code, but scientists are starting to notice patterns in how the virus is mutating.

If the Institute for Print and Media Technology at Chemnitz University of Technology has its way, many loudspeakers of the future will not only be as thin as paper, but will also sound impressive. This is a reality in the laboratories of the Chemnitz researchers, who back in 2015 developed the multiple award-winning T-Book—a large-format illustrated book equipped with printed electronics. If you turn a page, it begins to sound through a speaker invisibly located inside the sheet of paper. “The T-Book was and is a milestone in the development of printed electronics, but development is continuing all the time,” says Prof. Dr. Arved C. Hübler, under whose leadership this technology trend, which is becoming increasingly important worldwide, has been driven forward for more than 20 years.

“Considering the whole industry is still in its preliminary stage, BSN has a long way to go,” Liu said. “It’s expensive to build a blockchain. Different platforms have different structures. Data are not interchangeable. Relevant projects are hard to promote. These problems have yet to be addressed by BSN.”


Last year was a big year for blockchain projects in China after President Xi Jinping called for further development of the technology at the end of 2019, but the country continues to shun cryptocurrencies like bitcoin.
