Sources: Coronavirus pandemic may have started in Chinese laboratory 2020/04/15 Fox News
Sources believe coronavirus outbreak originated in Wuhan lab as part of China’s efforts to compete with US Bret Baier By Bret Baier, Gregg Re | Fox News There is increasing confidence that the COVID-19 outbreak likely originated in a Wuhan laboratory, though not as a bioweapon but as part of China’s attempt to demonstrate that its efforts to identify and combat viruses are equal to or greater than the capabilities of the United States, multiple sources who have been briefed on the details of early actions by China’s government and seen relevant materials tell Fox News.

Spintronics is about the coupled electron spin and charge transport in condensed-matter structures and devices. (Spin caloritronics Gerrit E. W. Bauer, Eiji Saitoh & Bart J. van Wees Nature Materials volume 11, pages391–399(2012) Published: 23 April 2012 )
内田氏が所属する東北大学の研究室は、温度差や音波を「スピン流」(スピンの流れ)に変換する技術を次々と開発してきた。スピン流に変換した後に、微小電力に変換して取り出す技術も確立している。 2008年には磁性体に温度差をつけるとスピン流が生じる「スピンゼーベック効果」を発見し、2010年に絶縁体でもスピンゼーベック効果が生じることを明らかにした。これにより「spin caloritronics」という新たな研究分野が誕生し、東北大学はNECと共同で新たな熱電変換素子の実現に取り組むことになった。(熱や音、光のエネルギーを、1つの素子で微小電力へ スピン流を使って東北大学が実現 河合 基伸 2015.01.28 日経 x TECH)

Magnetic Skyrmion as a Spintronic Deep Learning Spiking Neuron Processor IEEE Transactions on Magnetics Volume: 54 , Issue: 8 , Aug. 2018 DOI: 10.1109/TMAG. In this paper, the design of skyrmion-based devices to emulate biological synapses and neurons is explored, and skyrmionic synapse-based crossbar architectures driving skyrmionic neurons are proposed. We perform a systematic device-circuit-architecture co-design for digit recognition with the MNIST handwritten digits dataset to evaluate the feasibility of our proposal.
For approximately 2 decades, “therapeutic angiogenesis” has been studied as an investigational approach to treat patients with symptomatic PAD. Despite literally hundreds of positivepreclinical studies, results from human clinical studies thus far have been disappointing. (Therapeutic Angiogenesis for Peripheral Artery Disease Lessons Learned in Translational Science JACC Basic Transl Sci. 2017 Oct; 2(5): 503–512.)
The results of this review do not support the use of therapy with the growth factors FGF, HGF or VEGF in people with PAD of the lower extremities to prevent death or major limb amputation or to improve walking ability. However, … (Growth factors for angiogenesis in peripheral arterial disease 08 June 2017 cochranelibrary.com)
In this Review, data from phase II and III clinical trials of therapeutic angiogenesis in patients with PAD will be presented and discussed. Potential explanations for the limited success of therapeutic angiogenesis in humans will be viewed in the context of advances in our understanding of the complex mechanisms underlying angiogenesis and vascular remodelling.

Therapeutic angiogenesis is an application of biotechnology to stimulate new vessel formation via local administration of pro-angiogenic growth factors in the form of recombinant protein or gene therapy, or by implantation of endothelial progenitor cells that will synthesize multiple angiogenic cytokines. Numerous experimental and clinical studies have sought to establish ‘proof of concept’ for therapeutic angiogenesis in PAD and myocardial ischaemia using different treatment modalities, but the results have been inconsistent.
