Paul Krugman and the “Ersatz” Theory of Private Currencies
George SelginAlthough I ' ve devoted many essays here to exploding myths about historical private currencies, there ' s one I ' ve yet to directly challenge. That ' s the belief that such currencies only thrive in the absence of official alternatives. Otherwise, the argument goes, people would drop private currencies like so many hot rocks. Since this opinion assumes that private currencies are inevitably inferior to official ones, I hereby christen it the " ersatz " theory of private currency. Note that " currency " means circulating or (in today ' s digital context)peer-to-peer exchange media: nobody denies that other so...

The Macro View – Health, Economics, and Politics and the Big Picture. What I Am Watching Here And Abroad.
June 09, 2022 Edition-----The Russian war on Ukraine is now well over 100 days old. The destruction and deaths are just awful and the world is being seriously re-shaped. Where this ends is unknowable but unlikely to be good.In the US we are seeing almost daily mass shootings and no-one seems to know what to do. Just pathetic.In the UK the hangover is slowly lifting after the 4 day royal celebration.In OZ we are having an energy crisis which we hope we will find solutions for soon!-----Major Issues.------https://www.theaustralian.com.au/business/economics/australias-labor-government-faces-a-whole-new-economic-ball-game/news...

Decreased Ribosomal Biogenesis in Some Long-Lived Individuals
Ribosomes in a cell are where proteins are assembled according to a messenger RNA blueprint. Like all cellular components, ribosomes are regularly created and recycled. Reduced production of new ribosomes is a feature of calorie restriction, slowed aging accompanied by a lower output of new proteins. Further, genetic alterations that force a reduction in ribosomal biogenesis also modestly slow aging in animal studies, so it is thought that the pace of protein production is a relevant mechanism in the connection between cellular metabolism and aging. Researchers here extend this line of research into humans, looking at ribo...

The Top 10 Super-Creepy Medical Technologies
We are all for new technologies here, spending our days researching where the science of medicine goes. With that said, every now and then we see something so creepy that it freaks out even the seasoned team of The Medical Futurist.
So here we collected ten examples of either super creepy medical technologies or ingeniously evil uses of perfectly innocent technologies.
The blood drawing robots
First, this doesn’t really sound creepy. Drawing blood might not be our favourite thing, but nothing of a terror for most of us either. Vein scanners are around for a while, actually being a useful little tool ...

Spray Blocks SARS-CoV-2 Entry into Nasal Cells
Researchers at the University of British Columbia, and collaborators, created a nasal spray that can block the entry of SARS-CoV-2 into cells in the nasal cavity, potentially offering protection and treatment for COVID-19. Excitingly, in lab tests, t...

If You ’ ve Seen One Robot – Wait, What?
BY KIM BELLARD
If You’ve Seen One Robot – Wait, What?
We think we know robots, from the old school Robbie the Robot to the beloved R2-D2/C-3PO to the acrobatic Boston Dynamics robots or the very human-like Westworld ones. But you have to love those scientists: they keep coming up with new versions, ones that shatter our preconceptions. Two, in particular, caught my attention, in part because both expect to have health care applications, and in part because of how they’re described.
Hint: the marketing people are going to have some work to do on the names.

What Has A.I. In Medicine Ever Done For Us? At Least 50 Things!
Remember Monty Python’s brilliant Life of Brian movie scene where the Judean Jewish insurgent commando, planning the abduction of Pilate’s wife in return for all the horrors they had to endure from the Roman Empire, asks the rhetorical question: what have the Romans ever done for us? With the hype and overmarketing, not to speak about the fears around A.I, we asked the same question. What has A.I. in medicine ever done for us? Well, we found at least 50 things.
I have 50 responses to the pressing question on everyone’s mind who is interested in healthcare but tired of the hype or the doomsday scenarios around A.I....

We report that whereas microglia are characterized by marked gene-level alterations related to negative regulation of protein phosphorylation and phagocytic vesicles, astrocytes show activation of enzyme- or peptidase-inhibitor signaling after detectable changes in BBB permeability. We also identify several genes enriched in these pathways that are notably altered after BBB breakdown. Our data reveal that microglia and astrocytes play an active role in maintaining BBB stabilization and corralling infiltrating cells, and thus might potentially function in ameliorating the lesions and neurologic disabilities in CNS diseases....

The Macro View – Health, Economics, and Politics and the Big Picture. What I Am Watching Here And Abroad.
December 16 2021 Edition ----- On the global stage we are getting an increasing feeling that the old world order that resulted from the 2nd World War is breaking down with China and Russia both stirring up trouble. It all seems to be spinning out of control! – Climate Change also seems to be out of control with crazy weather all over! Tornadoes in the US a current example! Elsewhere the COVID seems to be coming back with a vengeance in the UK, Europe and the US – and Asia also getting worse. Christmas looks to be under threat a little. In OZ we are into the pre-Christmas slow down but with frenzied pre-election positio...

This study nicely illustrates the importance of the cellular metabolic state of myeloid cells: it highlights that not only the availability of glucose, but also its channeling into different pathways (glycolysis versus glycogen synthesis) contributes to maintaining proper myeloid function.

In conclusion, in less common and visible cardiovascular diseases, it is crucial to recognize substantial progress and achievement, given that penetration of such information into clinical practice and the patient community can be inconsistent. Diseases such as hypertrophic cardiomyopathy, pulmonary arterial hypertension, and ATTR cardiac amyloidosis, once linked to a uniformly adverse prognosis, are now associated with the opportunity for patients to experience satisfactory quality of life and extended longevity.

Digital Health Interests Of Pharma Giants Boehringer Ingelheim, Takeda, Astrazeneca, Amgen And Roche
With their extending reaches, resources and influence, pharmaceutical heavyweights have the potential to shape the digital health landscape to line up with their interests. And to have a better picture of where those interests lie, it is worth taking a look at what moves pharma giants are making in this sphere. With this in mind, we started a series of articles focusing on the digital health efforts of 14 global pharma companies.
The first article explored developments coming from Johnson & Johnson, Pfizer, Bayer and Novartis, while the second article investigated those coming from Merck, GlaxoSmithKline, AbbV...

Quantum Computing ’ s Sputnik Moment
By KIM BELLARD
General Mark A. Milley, chairman of the Joint Chiefs of Staff, recently expressed grave concern about China’s reported test of a hypersonic missile: “I don’t know if it’s quite a Sputnik moment, but I think it’s very close to that. It has all of our attention.” Maybe it should be, but General Milley may have missed the real 21st-century version of a Sputnik moment: China has claimed huge breakthroughs in quantum computing.
It’s inside baseball to those of us who are neither computer experts nor quantum physicists, but let’s put it this way: the countries/companies that domi...
