A description of gravity compatible with the principles of quantum mechanics has long been a widely pursued goal in physics. Existing theories of this ‘quantum gravity’ often involve mathematical corrections to Heisenberg’s Uncertainty Principle (HUP), which quantifies the inherent limits in the accuracy of any quantum measurement. These corrections arise when gravitational interactions are considered, leading to a ‘Generalized Uncertainty Principle’…

UAE’s Hope mission to Mars arrives today: How to watch
The Emirates Mars Mission “Hope” is a United Arab Emirates Space Agency uncrewed mission to Mars. It’s slated to enter Mars orbit on February 9, 2021. It’ll be followed on February 10 by China’s Tianwen-1 mission and, on February 18, by NASA’s Perseverance mission. Source: https://earthsky.org/space/missions-to-mars-uae-hope-china-tianwen-1…
IBM Quantum Computers Now Finish Some Tasks In Hours, Not Months
IBM has found a way to combine a new program execution environment, Qiskit, with a balance of “classical” and quantum computing to deliver a 100 times speedup for tasks that depend on iterative circuit execution. Computations that take months now will take mere hours, IBM said. Engadget reports: Qiskit by itself allows more circuits to run at a “much faster” rate,…
The Future of Jobs is Here: 10 Courses to Take in 2021
By Betty Vandenbosch, Chief Content Officer, Coursera As the new year unfolds, many challenges from 2020 persist: the pandemic continues to affect economies around the world and unemployment rates are still high. As we prepare to take advantage of new opportunities in 2021, professional development is top of mind for many. How can I gain […]

Get inspiration and advice from Paulina’s story—and see how she’s using AI to improve healthcare in Ghana!
Meet Paulina, a final-year medical student exploring how artificial intelligence (AI) can be used to solve healthcare delivery problems in West Africa. Read on to see how she’s using what she’s learned from her courses to not only expand educational opportunities in her community, but tackle community health projects through programming and data analysis. I […]

New Study: A Zero-Emissions America is Now Pretty Cheap
“Until recently, it was unclear whether variable renewable energy, nuclear, or fossil fuel with carbon capture and storage would become the main form of generation in a decarbonized electricity system,” argues a recently-published analysis titled Carbon-Neutral Pathways for the United States. “The cost decline of variable renewable energy over the last few years, however, has definitively changed the situation.” Ars Technica…
JADES will go deeper than the Hubble Deep Fields
Astronomers announced this month that a new deep-field survey called JADES will be carried out with the James Webb Space Telescope, Hubble’s much-anticipated successor. The Webb is due to launch later this year. Source: https://earthsky.org/space/jades-deep-field-surveys-epoch-of-1st-galaxies…
What’s the weather like on Titan?
Most of the planets in our solar system have some sort of atmosphere and many have dynamic weather systems. But only one moon in the solar system, Saturn’s large moon Titan, can say the same. Source: https://earthsky.org/space/titan-saturns-moon-weather-seasons-methane-rain-storms…
Reddit Joins With Ethereum Foundation To Build Scaling Tools
Reddit is growing its role in the Ethereum ecosystem, with the goal of building out scaling tools for the blockchain network. From a report: The social media platform announced this week that it was expanding its work with the Ethereum Foundation to provide development resources to scaling tools. In the announcement, posted to the Ethereum subreddit, Reddit employee u/jarins said the…
A benchmark for single-electron circuits
Manipulating individual electrons with the goal of employing quantum effects offers new possibilities and greater precision in electronics. However, these single-electron circuits are governed by the laws of quantum mechanics, meaning that deviations from error-free operation still occur—albeit (in the best possible scenario) only very rarely. Thus, insights into both the physical origin and the metrological aspects of this fundamental uncertainty…
