Top Cleric at Iran’s Southern Khorasan Province, Alireza Ebadi: Humanity Must Fight the “Two-Legged Viruses” of Western Liberalism, Which Are Even Worse than the Coronavirus

Posted by in categories: biotech/medical, electronics

Islamic religious scientist points out a hidden existential threat, worse even than the SARS-CoV-2 virus: two-legged viruses that spread liberal democracy.

Iranian scholar Alireza Ebadi, Supreme Leader Ayatollah Ali Khamenei’s representative in the Southern Khorasan Province, said in a lecture that aired on Khorasan Jonoobi TV (Iran) on April 10, 2020 that the “virus” of Western liberal democracy is even worse than the coronavirus since it has caused the deaths and displacement of millions of people, two world wars, coups in various countries such as Iraq, the spread of cholera in Yemen, and Western intervention in Syria, Afghanistan, India, Pakistan, and elsewhere. Ebadi expressed hope that once humanity defeats the “pest” of the coronavirus, it will “make sure the greatest pests of all do not escape.” He added: “May God [save] humanity from [the] two-legged viruses.”

New DisplayPort spec enables 16K video over USB-C

Posted by in categories: computing, electronics

DisplayPort Alt Mode 2.0 is a new standard from the Video Electronics Standards Association that allows USB 4 to offer all the bells and whistles of the DisplayPort 2.0 standard as well as transmitting USB data. That means support for 8K displays at 60Hz with HDR, 4K displays at 144Hz with HDR, or even 16K (15360×8460) displays at 60Hz with compression. It’s a big step towards USB Type-C becoming a true jack-of-all trades connector.

The USB 4 spec can already transmit DisplayPort data, but AnandTech reports that the new standard remaps USB-C’s high speed data pins to unlock more bandwidth for video. USB 4 is bidirectional, meaning it can carry up to 40Gbps of data in either direction. However, video doesn’t need to go both ways — you only really need data to pass from your laptop to your monitor (for example). This alt mode means that all that bandwidth can be used to just send video one way, meaning you get a maximum raw bandwidth of up to 80Gbps.

Las Vegas’ Venetian Resort will utilize thermal cameras, medics when it reopens

Posted by in categories: electronics, security

Thermal cameras sound like a great idea for folks who are looking for a false sense of security and/or lack a basic understanding of what being an asymptomatic carrier means…

When the Venetian Resort reopens following the lifting of Las Vegas’ stay-at-home order, it will empoy thermal screening and full-time medics.

Researchers discover ferroelectricity at the atomic scale

Posted by in categories: electronics, materials

As electronic devices become progressively smaller, the technology that powers them needs to get smaller and thinner.

One of the key challenges scientists face in developing this technology is finding materials that can perform well at an ultrathin size. But now, Berkeley researchers think they may have the answer.

Led by Sayeef Salahuddin, professor of electrical engineering and computer sciences, and graduate student Suraj Cheema, a team of researchers has managed to grow onto silicon an ultrathin material that demonstrates a unique electrical property called ferroelectricity. The duo’s findings were published in the April 22 issue of Nature.

Glutamine Attenuates Acute Lung Injury Caused by Acid Aspiration

Posted by in categories: biotech/medical, electronics

Inadequate ventilator settings may cause overwhelming inflammatory responses associated with ventilator-induced lung injury (VILI) in patients with acute respiratory distress syndrome (ARDS). Here, we examined potential benefits of glutamine (GLN) on a two-hit model for VILI after acid aspiration-induced lung injury in rats. Rats were intratracheally challenged with hydrochloric acid as a first hit to induce lung inflammation, then randomly received intravenous GLN or lactated Ringer’s solution (vehicle control) thirty min before different ventilator strategies. Rats were then randomized to receive mechanical ventilation as a second hit with a high tidal volume (TV) of 15 mL/kg and zero positive end-expiratory pressure (PEEP) or a low TV of 6 mL/kg with PEEP of 5 cm H2O. We evaluated lung oxygenation, inflammation, mechanics, and histology. After ventilator use for 4 h, high TV resulted in greater lung injury physiologic and biologic indices. Compared with vehicle treated rats, GLN administration attenuated lung injury, with improved oxygenation and static compliance, and decreased respiratory elastance, lung edema, extended lung destruction (lung injury scores and lung histology), neutrophil recruitment in the lung, and cytokine production. Thus, GLN administration improved the physiologic and biologic profiles of this experimental model of VILI based on the two-hit theory.

Keywords: acid aspiration, ARDS, glutamine, ventilator-induced lung injury.

Acute respiratory distress syndrome (ARDS) is a catastrophic syndrome among critically ill patients. One of its major causes is acid aspiration as an initial pneumonitis that may be complicated by subsequent bacterial pneumonia after inhaling low pH gastric fluid [1, 2, 3, 4]. Gastric fluid aspiration frequently occurs in trauma or critical patients with head trauma, alcohol or cerebrovascular accidents, and is also a complication of general anesthesia that occurs in 1 in 2000–3000 cases when anesthetics are used [3, 4].

Synchrotron X-ray sheds light on some of the world’s oldest dinosaur eggs

Posted by in category: electronics

An international team of scientists led by the University of the Witwatersrand in South Africa, has been able to reconstruct, in the smallest details, the skulls of some of the world’s oldest known dinosaur embryos in 3D, using powerful and non-destructive synchrotron techniques at the ESRF, the European Synchrotron in France. They found that the skulls develop in the same order as those of today’s crocodiles, chickens, turtles and lizards. The findings are published today in Scientific Reports.

University of the Witwatersrand scientists publish 3D reconstructions of the ~2cm-long skulls of some of the world’s oldest dinosaur embryos in an article in Scientific Reports. The embryos, found in 1976 in Golden Gate Highlands National Park (Free State Province, South Africa) belong to South Africa’s iconic dinosaur Massospondylus carinatus, a 5-meter long herbivore that nested in the Free State region 200 million years ago.

The scientific usefulness of the embryos was previously limited by their extremely fragile nature and tiny size. In 2015, scientists Kimi Chapelle and Jonah Choiniere, from the University of Witwatersrand, brought them to the European Synchrotron (ESRF) in Grenoble, France for scanning. At the ESRF, an 844 metre-ring of electrons travelling at the speed of light emits high-powered X-ray beams that can be used to non-destructively scan matter, including fossils. The embryos were scanned at an unprecedented level of detail — at the resolution of an individual bone cell. With these data in hand, and after nearly 3 years of data processing at Wits’ laboratory, the team was able to reconstruct a 3D model of the baby dinosaur skull. “No lab CT scanner in the world can generate these kinds of data,” said Vincent Fernandez, one of the co-authors and scientist at the Natural History Museum in London (UK).

Suppression of NLRP3 Inflammasome

Posted by in categories: biotech/medical, electronics

This is a good one pass it on

This study aimed to explore whether the therapeutic effects of EPO rely on the suppression of the NLRP3 inflammasome and the specific mechanisms in an LPS-induced ALI mouse model. ALI was induced in C57BL/6 mice by intraperitoneal (i.p.) injection of LPS (15 mg/kg). EPO was administered intraperitoneally at 5 U/g after LPS challenge. The mice were sacrificed 8 h later. Our findings indicated that application of EPO markedly diminished LPS-induced lung injury by restoring histopathological changes, lessened lung wet/dry (W/D) ratio, protein concentrations in bronchoalveolar lavage fluid (BALF) and myeloperoxidase (MPO) levels. Meanwhile, EPO evidently decreased interleukin-1β (IL-1β) and interleukin-18 (IL-18) secretion, the expression of NLRP3 inflammasome components including pro-IL-1β, NLRP3, and cleaved caspase-1 as well as phosphorylation of nuclear factor-κB (NF-κB) p65, which may be associated with activation of EPO receptor (EPOR), phosphorylation of Janus-tyrosine kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3)

Taken together, this study indicates that EPO can effectively attenuate LPS-induced lung injury in mice by suppressing the NLRP3 inflammasome, which is dependent upon activation of EPOR/JAK2/STAT3 signaling and inhibition of the NF-κB pathway.
