Quantum Supremacy Achieved ?

Quantum computers has been on news a lot lately. Scientists claim to have achieved “quantum supremacy”, a breakthrough that could change computing history. But has that breakthrough really happened or not? Google Confirms Achieving Quantum Supremacy https://gizmodo.com/google-confirms-achieving-quantum-supremacy-1839288099 Google scientists confirmed in a blog post that their quantum computer had needed just 200 seconds to solve

A Carbon Nanotube Microprocessor Mature Enough To Say Hello IEEE Spectrum – IEEE Spectrum

There has been for several years talking that nanotube transistors are coming to use and they can be better than traditional transistors made of silicon. I see this news as a major milestone. IEEE Spectrum writes: https://spectrum.ieee.org/nanoclast/semiconductors/processors/modern-microprocessor-built-using-carbon-nanotubes Engineers at MIT and Analog Devices have created the first fully-programmable 16-bit carbon nanotube microprocessor RV16X-NANO. It’s the

Turns out the science saying screen time is bad isn’t science | TechCrunch

https://techcrunch.com/2019/01/14/turns-out-the-science-saying-screen-time-is-bad-isnt-science/ Is screen time good or bad? Hard to sau for sure. A new study is making waves in the worlds of tech and psychology by questioning the basis of thousands of papers and analyses with conflicting conclusions on the effect of screen time on well-being. There seems to be a lot bad science.

Amoeba finds approximate solutions to NP-hard problem in linear time

https://phys.org/news/2018-12-amoeba-approximate-solutions-np-hard-problem.html This is intresting finding that Researchers have demonstrated that an amoeba (a single-celled organism) has unique computing abilities. The researchers found that an amoeba can find reasonable (nearly optimal) solutions to the TSP in an amount of time that grows only linearly as the number of cities increases. Traveling Salesman Problem (TSP) is an
