The Silicon Quantum Electronics Workshop will have 200 researchers sharing insights and technology advancements about building the world’s first silicon quantum computer.

NSW university has set up a Quantum Computer Company

Silicon Quantum Computing Pty. Ltd. (SQC) is working to create and commercialize a quantum computer based on world-leading intellectual property acquired from the Australian Centre of Excellence for Quantum Computation and Communication Technology (CQC2T). We have set ourselves a bold ambition: to develop a 10-qubit quantum integrated circuit prototype in silicon by 2022.

PANC-1 human pancreatic cancer cells are characterized by their ability to proliferate aggressively under hypovascular and hypoxic conditions in the tumor microenvironment, displaying a remarkable tolerance to nutrition starvation. The antiausterity strategy is a new approach in anticancer drug discovery aiming at the identification of potent agents that inhibit preferentially the survival of tumor cells during a limited supply of nutrients and oxygen. The new 5,8′-coupled naphthyldihydroisoquinoline alkaloid ancistrolikokine E₃ (4), isolated from the Congolese liana Ancistrocladus likoko, showed potent preferential cytotoxicity against PANC-1 cells under nutrient-deprived conditions, with a PC₅₀ value of 2.5 μM, without exhibiting toxicity in normal, nutrient-rich medium. The compound was found to induce dramatic alterations in cell morphology, leading to cell death. Moreover, it inhibited significantly PANC-1 cell migration and colony formation in a concentration-dependent manner. This study on 4 provides the first live evidence of the effect of a naphthyldihydroisoquinoline alkaloid against PANC-1 cells in nutrient-deprived medium. Mechanistic investigations conducted suggest that compound 4 is a potent inhibitor of the activation of the Akt/mTOR pathway. Furthermore, it inhibited the expression levels of the key autophagy regulators Atg5, Atg12, Beclin-1, LC3-I, and LC3-II. The results demonstrated that ancistrolikokine E₃ (4) is a potent early-stage inhibitor of the autophagy pathway in PANC-1 human pancreatic cancer cells. Ancistrolikokine E₃ (4) and related naphthylisoquinoline alkaloids are promising potential lead compounds for anticancer drug development based on the antiausterity strategy.

The success of SpaceX Falcon Heavy on its first launch was not just luck. Although this will be confirmed in 2019 and 2020 based upon what happens with about five planned Falcon Heavy launches.

Before the Falcon Heavy flight Musk predicted a 50 percent to 70 percent chance of success because of concerns over the difficulty predicting how the vehicle would respond to extreme aerodynamic stresses and vibrations from the clustered engines.

Blue Origin has provided additional details relating to its New Glenn rocket this week via the release of its Payload User Guide that is designed to aid customers interested in launching their payloads on their launch vehicle with requirements and capabilities. Meanwhile, work is continuing on the company’s Cape Canaveral launch site and the refit of its booster landing ship.

Blue Origin is quietly preparing to head into the orbital launch market with its New Glenn rocket, named after the first American to orbit the Earth, John Glenn.

Ground control to major Jeff (Bezos).

Amazon Web Services (AWS), the company’s cloud computing arm, just announced a new offering aimed at satellite operators.

The news: At its annual re: Invent conference in Seattle this week, the web giant unveiled a service that lets owners of satellites rent time on Amazon-managed ground stations to send and receive data from orbit. The service, called AWS Ground Station, works in much the same way as Amazon’s well-established business for tapping computing capacity via the cloud.
