UVC is the kind of UV that’s more energetic than the UV we get in sunlight. It’s shorter wavelength. Paradoxically, at around 222nm the light is so energetic it is stopped by almost anything — even the layer of dead cells or fluid on the surface of our eye. But for a naked virus floating in the air, UVC is deadly — it will damage all nucleic acids to the point where the viruses and bacteria are unable to replicate. In contrast, for our skin cells, photons of the far UVC wavelengths (200 -230nm) can’t penetrate far enough to cause any damage that matters.
Far-UV-C radiation: An emerging tool for pandemic control. Blatchley III, Brenner et al (2022)
The UVC coming off the sun is stopped by the ozone in the stratosphere, so it doesn’t reach us on the ground. The kind of UV that causes burns, cataracts and skin cancer is from longer wavelength UVB and UVA which can penetrate the surface and damage our DNA.
Could a New Ultraviolet Technology Fight the Spread of Coronavirus?

Sometimes Randomized Controlled Trials are not the golden trophies of science that some say they are. (Like yesterday’s Ivermectin study). While some say that nothing less than an RCT will do, actually, sometimes it’s just silly to do one. And all RCT’s will wallow on the rocks of confirmation bias if they try to study something people already know the answer to.
For a long time there were no RCT studies showing benefits from parachutes — yet people continued to use them. It wasn’t until 2018 that a paper was finally published, surprisingly showing that there was no statistical difference in jumping with or without one from an average altitude of 4,000m.
This satirical paper makes real points about the flaws of the hallowed RCT’s:
It’s easy to design an RCT to show the opposite of the truth. Reading the abstract of a paper is rarely enough. Reading a news headline, even less so. Details are everything. RCT’s are not random if the test subjects have opinions and can self-select themselves out of the experiment.
These authors are black-belt professionals at medico-lingo. Those that appreciate the wit will want to read the whole thing rather than just the snippets below […]
Late last week a large prospective “study” showed that ivermectin was useless so it got headline reporting at the Wall Street Journal, unlike the other 80 controlled studies the newspaper ignored. This study is not even a peer reviewed paper, nor is it even news — The TOGETHER Trial announced results way back in August last year, but haven’t officially published the paper yet.
It’s a case of PR now, details later.
Thanks to the FLCCC we know some of the reasons the trial was never likely to succeed. And given that several groups involved in the trial were also big clients of Pfizer, it was a very convenient failure. Bear in mind, “fail” is relative — despite all the handicaps below, the Relative Risk of dying of Covid with low dose ivermectin was still 0.82 (0.44-1.52). Meaning they found a 20% lower mortality rate, but it wasn’t statistically significant when done with a low, late dose in the wrong way, with the wrong type of trial, with the wrong type of participants.

Fascinating. Could one shot of radiation calm Covid infected lungs and stop the severe cytokine storm?
In a trial in the US, five very sick Covid patients with a median age of 90 were given a “low dose” (which is not so low) of 1.5 Grey (150 Rad) of Photon beam radiotherapy (in a front and back beam configuration.) It took only 10 – 15 minutes, and four of the five showed “rapid improvement” in 24 hours. Their oxygen levels and alertness improved. They were sent home from hospital 12 days later.
The good thing about this is that apparently most hospitals already have this equipment, so they could start helping people right away (assuming it works, which we don’t know yet).
Radiation isn’t anti-viral, it’s anti-inflammatory
In theory, the shot of radiation is not “killing the virus” but is changing the immune response — and may be able to stop the deadly cascade of the cytokine storm. It calms the immune system in at least three ways (see the chart).
Anti-inflammatory treatment for Covid-19.
The curious thing about this is that it is an old treatment, and an old idea. “Hormesis” is a phenomenon where low grade […]
Here’s a tantalizing bit of gene research. Scientists were able to switch off a central gene in the nucleus of a mouse cell. That in turn meant the mouse’s mitochondria started failing (I’m going to be talking a lot more about these fascinating bits of machinery in our cells). After two months, the poor lab mice were wrinkled, going bald and their organs were aging rapidly, but lo, after the gene in the nucleus was switched on again, the mitochondria were restored, and wow, all the hair and skin grew back to what it had been before.
Mitochondria have their own DNA loops.
Why get excited about mitochondria? These are tiny biological batteries we have inside every cell. The are the mini-factories burning sugar or fat, generating free radicals on a mass scale and churning out the chemical energy that is then used in most of the chemical reactions in our body. They are turning up in every second paper these days related to aging. These little organelles are so important and rule breaking they even have their own DNA loops with 37 genes — this is the only genetic material in us that is not part of the […]
Was that a half-truth or a lie by omission? Trick question…
Malcolm Kendrick reports on a new study that he says should “shake the foundations of medical research” but laments that it almost certainly won’t.
In the year 2000, the US National Heart Lung, and Blood Institute (NHLBI) insisted that all researchers register their “primary aim” and then later their “primary outcome” with clinicaltrials.gov. This one small change in the way medical studies were reported transformed the “success” rates in peer reviewed papers. Before 2000, fully 57% of studies found the success they said they were testing for, but after that, their success rate fell to to a dismal 8%. When people didn’t have to declare what their aim was, they could fish through their results to find some positive, perhaps tangential association, and report that as if they had been investigating that effect all along. The negative results became invisible. If a diet, drug or treatment showed no benefit at all, or turned up bad results, nobody had to know.

It’s not like climate science suffers from unpublished “negative results” — no, it’s more […]
Researchers at Harvard wondered if high risk heart patients were more likely to die if they turned up at the hospital during national cardiology meetings when most of the experts are not around. Instead, it turns out that mortality rates during the conferences fell from 70% to 60%. Oops.
Who do you want to see if you’re sick? In this situation, possibly not your specialist.
High-risk patients with certain acute heart conditions are more likely to survive than other similar patients if they are admitted to the hospital during national cardiology meetings, when many cardiologists are away from their regular practices.
Sixty percent of patients with cardiac arrest who were admitted to a teaching hospital during the days when cardiologists were at scientific meetings died within 30 days, compared to 70 percent of patients who were admitted on non-meeting days.
“That’s a tremendous reduction in mortality, better than most of the medical interventions that exist to treat these conditions,” said study senior author Anupam Jena, assistant professor of health care policy at HMS, internist at Massachusetts General Hospital and faculty research fellow at the National Bureau of Economic Research. There is substantial ambiguity in how medical care […]
The word revolution is overused and done to death. But in the case of medicine, we are in the midst of one. Here are three stories just out this week. It’s possibly none of these will end up being useful clinically, but the sheer volume of results like these mean that sooner or later getting a diagnoses of cancer will mean something very different. It’s time for good news stories. Let’s redirect the gravy train of pointless climate and renewables research. (Sell the ABC and use the money to double our medical research budget. How many lives might we change?*)
These are not instant miracles, but potential ones. The bladder cancer drug ultimately helped about a quarter of all patients. It was a small trial. Two patients of 68 appeared to reach the holy grail: to be tested free of cancer (though it doesn’t mean they are). The second news report talks about a small study targeting a similar mechanism to stop melanoma that only helps about 30% of patients — the study successfully predicted which ones. In both cases the idea is to stop the cancer from hiding from the immune system. Some cancer cells produce molecules called PD-1 […]
Something different to discuss – for the medical-revolution cynics among us. Cells from a human triple-negative breast cancer were implanted in mice under their mammary fat pads. Triple negative breast cancer is a nastier form of breast cancer which is harder to treat because these cells don’t respond to the usual anti-estrogenic drugs.
The mice were then allowed to eat only 70% as many calories as they would normally freely choose to eat. This is a particularly interesting study because it shows that calorie restriction inhibited the expression of certain micro RNAs even from foreign (non mouse) implanted breast cancer cells, and this apparently kept the cancer from spreading. Notably fatalities from cancers don’t usually come from the initial solid tumor but from the metastasized version, so this is potentially very useful.
The mechanism involves strengthening the matrix around the cancer cells. When these cancer cells have metastasized they produce more of these particular micro RNA’s which in turn appear to stop production of proteins that strengthen the extracellular matrix. In other words, the cancer cells probably use the micro RNA’s to degrade the cellular matrix around them in order to spread. The implications of this are both that the […]

This is another example of why I’m so passionate about getting research money out of dead-end efforts to change the weather and into medical research. The extraordinary news broke last week that the Mayo Clinic had used a genetically modified virus to cure treat one woman of metastasized and widely spread cancer – specifically myeloma. There are a lot of caveats, this research is quite risky, and it doesn’t apply to most people or most cancers, it is a proof of principle.
The potential for transformative medical breakthroughs is spectacular right now. Medicine is, after all, just an information game. The information is expensive but the material resources are dirt cheap — all the answers to the holy grail of the fountain of health are found in rearrangements of common elements — like the kind found in the dirt of a pot-plant. For the first time humanity has the tools to hunt and hammer out the information. If people knew what glittering marvels were within reach, they surely would want to channel our best and brightest and all our spare resources.
The main caveat here (a pretty big one) is that the trial had only […]
Three years ago I made the case for dumping renewables, and doubling medical research — and both occurred in last night’s budget. (Yes, I hear the cry that this is just more big-government funded bad-science, bear with me, I’ll get to that). First let me bask in the glory (wink).
I’m especially proud of the Op-Ed I wrote in The Weekend Australian in May 2011. Indeed it’s very much my driving mission — to redirect corrupted and wasteful tax funds towards better uses, and to help four year olds with cancer, and all the other variants of human pain.
It’s big biccies… The Abbott Government is setting up a 20 billion dollar medical research future fund, which is expected to distribute $1 billion to research annually by 2022-23. It’s being claimed it is the largest in the world (I am not entirely convinced, but nonetheless, it’s radically big). We currently spend about $800m a year on medical research, so this would really double it. (Spooky).
But I can feel the barbs of skeptical libertarians already — saying the money should have been used to pay off the debt or returned to the people who earned it — and I’m […]
Sometimes the consensus deniers are right, which is exactly why the term is so pointless and so profoundly unscientific.
The medical associations were unequivocal. Crash diets were a fad, unhealthy, and only slow sensible weight loss could work. So millions of people were fed expensive drugs for decades, monitored, and some even given risky bariatric surgery. Patients with Type II diabetes were expected to be treated for years, or possibly the rest of their lives. Nearly a tenth of the national health budget of the UK was spent managing diabetes. Fully 8% of the population have the condition in the US.
Now a new (albeit very very small) study cured diabetes in some cases in as little as a week with a diet that was thought to be bad.
In the trial the very low calorie diet was done for 8 weeks. Sticking to 600 calories a day is not easy (some reports say it was 800 cals). It’s about a quarter of what a normal guy would eat. But it shrinks fat in the pancreas and liver, and that seemingly returns insulin levels to normal. The really amazing thing is that the benefits turn out to stay around far […]
How much don’t we know? This week doctors announce that yes, really, there is a whole ligament in the human knee that we didn’t know about, and it’s not a small one tucked away but a mid-size one and “hidden” on the outside of the knee. They’ve named it the anterolateral ligament (ALL), and it does matter if it fails, people’s knees collapse suddenly. “Only” 97% of people have one. But how is this, it was first postulated by a surgeon in 1879, and took 134 years to find. For much of that time you might have been told there was a consensus on knee anatomy, and because thousands of doctors have done knee surgery and knee replacements are now de rigeur, you might have thought the science was settled.
Sorry about the graphic photo, but when I saw that headline, I thought this would be a tiny artifact. You need to see it to appreciate just how remarkable it is that this has been missed for so long. UPDATE: It’s so remarkable, I find Chrism comments below are useful #5, #8, #12, and quite possibly the ligament was known by another name, or associated with a different malady. Is […]
Here’s a topic close to my heart. Before I became involved in climate change and currencies, my hot topic-of-choice for years was medical research and health. In my honours degree I worked to get a tiny step closer to treating Duchenne Muscular Dystrophy. When I saw that The Australian Government was threatening to cut medical research, I wanted to put a razor fine point on just what muddy thinking costs us. This article I wrote is published in The Weekend Australian today. We can’t afford to get the decision wrong on climate change. We must fight the battles that matter, not build fortresses against imaginary foes.
Wasting money on climate change betrays sick Joanne Nova From: The Australian May 07, 2011 12:00AM
LOST opportunities are invisible but deadly. On climate change, the call to buy insurance by pricing carbon is a cop-out. Where is the cost-benefit analysis? We’re thinking of axing Australian medical research yet we’re supporting solar panel manufacturers in China. It doesn’t have to be this way.
All the money spent employing green police, subsidizing solar or researching how to pump carbon dioxide underground is money not spent on medical research. Opportunity cost is a killer. […]
