Here on Earth, we pay quite a lot of attention to the sun. It’s visible to us, after all, and central to our lives. But it is only one of the billions of stars in our galaxy, the Milky Way. It’s also quite small compared to other stars – most are at least eight times more massive.

These massive stars influence the structure, shape and chemical content of a galaxy. And when they have exhausted their hydrogen gas fuel and die, they do so in an explosive event called a supernova. This explosion is sometimes so strong that it triggers the formation of new stars out of materials in the dead star’s surroundings.

But there’s an important gap in our knowledge: astronomers don’t yet fully understand how those original massive stars themselves are initially formed. So far, observations have only yielded some pieces of the puzzle.

A Kenya Airways passenger who arrived from Guangzhou with flu-like symptoms has been quarantined at the Kenyatta National Hospital (KNH) over fears of the coronavirus.

A statement from Kenya Airways confirmed that the Kenyan passenger had travelled to Nairobi from Guangzhou on Tuesday.

“Decision to quarantine the passenger was reached by the Kenya Government port health authorities stationed at JKIA,” the statement reads.

The new Advanced Manufacturing Laboratory was unveiled to the public last week at its official dedication. Media, government representatives and industry partners got the chance to see all the AML has to offer and learn how they can partner with LLNL to advance American manufacturing.

Editor’s note: Geoff Woollacott is Senior Strategy Consultant and Principal Analyst at Technology Business Research. IBM and NC State are coperating on quantum computing development.

HAMPTON, N.H. – JPMorgan Chase announced on Jan. 22 the hiring of Marco Pistoia from IBM. A 24-year IBM employee with numerous patents to his credit, Pistoia most recently led an IBM team responsible for quantum computing algorithms. Algorithm development will be key to developing soundly engineered quantum computing systems that can deliver the business outcomes enterprises seek at a faster and more accurate pace than current classical computing systems.

A senior hire into a flagship enterprise in the financial services industry is the proverbial canary in the coal mine, as TBR believes such actions suggest our prediction of quantum achieving economic advantage by 2021 remains on target. Quantum executives discuss the three pillars of quantum commercialization as being:

Estimates of the clock and TMRCA for 2019-nCoV based on 27 genomes.

Following up on the analyses provided by Andrew Rambaut this is a brief report estimating the evolutionary rate and timing of the epidemic (date of the most recent ancestor (MRCA)) based on 27 publicly shared n2019-nCoV genome sequences. Compared to earlier analyses where several parameters had to be fixed, there is now enough information content in the sequences to obtain reasonable estimates of the clock and TMRCA without fixing parameters.
