The SARS-CoV-2 spike protein disrupts the cooperative function of human cardiac pericytes - endothelial cells through CD147 receptor-mediated signalling: a potential non-infective mechanism of COVID-19 microvascular diseaseScience & Medicine Blogs Dec 21, 2020 by bioRxiv Background Severe coronavirus disease 2019 (COVID-19) manifests as a life-threatening microvascular syndrome. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses primarily the capsid spike (S) protein to engage with its receptors and infect host cells. To date, it is still not known if the S protein alone, without the other viral elements, is able to trigger vascular cell signalling and provoke cell dysfunction. tags: #covid-19 #covid #endothelial #pericytes #cd147-receptor #receptor-mediated-signalling #microvascular #cytokines #s-protein |

| MIT just made aluminum 5x stronger with 3D printing |
|
MIT researchers have designed a printable aluminum alloy that's five times stronger than cast aluminum and holds up at extreme temperatures. Machine learning helped them zero in on the ideal recipe in a fraction of the time traditional methods would take. When 3D printed, the alloy forms a tightly packed internal structure that gives it exceptional strength. |

| How giant concrete balls on ocean floors could store renewable energy |
|
In an effort to reduce the use of precious land to build renewable energy storage facilities, the Fraunhofer Institute has been cooking up a wild but plausible idea: dropping concrete storage spheres down to the depths of our oceans. |

| Scientists discover caves carved by water on Mars that may have once harbored life |
|
If there is, or ever has been, life on Mars, the chances are it would exist in caves protected from the severe dust storms, extreme temperatures, and high radiation present on its surface. One place to focus our attention could be eight possible cave sites (called skylights) recently discovered by Chenyu Ding at Shenzhen University in China, and colleagues. |

| Using air to deflect lasers |
|
Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, reports an interdisciplinary research team in the journal Nature Photonics. |
