Many industries use heat-intensive processes that generally require the burning of fossil fuels, but a surprising green fuel alternative is emerging in the form of metal powders. Ground very fine, cheap iron powder burns readily at high temperatures, releasing energy as it oxidizes in a process that emits no carbon and produces easily collectable rust, or iron oxide, as its only emission.

COVID-19: Disruption to vaccine rollout as people trek for miles in snow for jabs - and others told to stay at home | UK News | Sky News

The disruption to the vaccine rollout comes after parts of the North saw snowfall overnight and more is forecast later today.
But, of course, the government planned in advance for the bad weather. Didn't they? Doesn't look like it. The UK pays an obscene amount for the upkeep of military forces. Can they not be deployed to affected areas?

On another D* thread, someone questioned the slow rollout of the vaccine. I said that, here in the UK, I can't tell the difference between the Tory government's gross incompetence on the one hand, and deliberate pursuit of a herd immunity strategy on the other.

Covid: Large trial of new treatment begins in UK | BBC News

A large-scale trial of a new treatment it is hoped will help stop Covid-19 patients from developing severe illness has begun in the UK.
Inhaling nebulised interferon beta stimulates the immune system cut the odds of a Covid-19 patient in hospital developing severe disease - such as requiring ventilation - by almost 80%.

You May Soon Be Able to Measure Blood Pressure From Your Finger

Wearable devices have become more sophisticated in recent years, with the ability to track everything from abnormal heart rates and atrial fibrillation to stress and even blood oxygen levels. However, monitoring blood pressure is a challenge for a wrist-worn device. Wearable components maker Valencell says it’s figured out how to measure blood pressure using photoplethysmography (PPG) heart rate sensors from your finger or wrist.
Apple has already filed its own patent on measuring blood pressure with an Apple Watch. It will be interesting to see how quickly this technology comes to market.

The Pandemic Could Disrupt Decades of Decline in Cancer Mortality | Gizmodo

A new report released Tuesday by the American Cancer Society provides some good news: Americans who had cancer in 2018 were less likely to die from it than they were a year earlier, continuing a steady decline in cancer mortality over the past 30 years. As hopeful as this trend is, though, there are still lower survival rates in different parts of the country and among Black Americans. Experts also worry that the covid-19 pandemic will end up erasing some of this progress.

Doctors found another strange coronavirus symptom no one can explain | BGR

Some of the people infected with the novel coronavirus who survive COVID-19 will then experience persistent symptoms for weeks or even months after the illness, in what’s known as “Long COVID.”
Doctors are still trying to understand the lingering symptoms, with the Westchester Medical Center in New York running a treatment and study program for long haulers.
Now, a new report explains another strange coronavirus symptom that can appear with Long COVID: Some people have experienced skin peeling off their hands and a strange purple discoloration in their fingers.

Here’s What to Know About the Universal Flu Vaccines Being Studied | weather.com

One main reason humans need to get a flu vaccine annually; flu strains mutate regularly so vaccines need to be slightly altered every year. During past flu seasons, the CDC has noted a vaccine effectiveness range between 40-60%, and a reduced the risk of flu-related illness by 40-60% within the overall population.

There are, however, several “universal” flu vaccines currently being studied that aim to make annual flu vaccinations a thing of the past.

New Research Shows How Covid-19 Can Trigger Brain Damage | Gizmodo

New research out today looks to bring us closer to understanding how covid-19 can cause brain damage. The study suggests that while the viral infection may not directly reach the brain in most cases, it can spark the sort of destructive inflammation that’s seen with other neurological conditions, like stroke.

Alzheimer's: the 'switch-on moment' discovered | The Conversation

The past three decades saw a dramatic improvement in our understanding of what brings about Alzheimer’s disease. Two proteins are thought to be responsible: amyloid and tau. The most widely accepted theory is that a critical level of amyloid in the brain triggers the build-up of the more toxic tau protein. This has led to several studies testing drugs and vaccines that remove amyloid and tau to see if they can improve or even prevent dementia. Results have been disappointing.
But the hunt is on for new tests.

Millions of people, including many members of my family are alive today because of they were vaccinated in childhood.

The lunacy and selfishness of the keyboard warriors and their anti science, anti fact crusade against vaccines has killed more people in the recent years than the vaccines have caused harm in the past half a century.

Covid Pandemic: Microbiomes Could Be Key to Stopping Spread of Future Viruses - Bloomberg

In the Western world, humans spend 90% of their time indoors. The average American spends even more than that—93%—inside buildings or cars. For years scientists have sounded the alarm that our disconnect from the outdoors is linked to a host of chronic health problems, including allergies, asthma, depression, irritable bowel syndrome, and obesity. More recently, experts in various fields have begun studying why buildings, even those designed to be as germ-free as possible, are vectors for disease, not the least Covid-19.

Biomarker of Alzheimer's found to be regulated by sleep cycles | New Atlas

Scientists at Washington University School of Medicine (WUSM) in St. Louis have spent some years investigating the links between circadian rhythm and Alzheimer’s, and have recently been making some real inroads. Following a 2018 study demonstrating how disrupted sleep can accelerate the buildup of toxic plaques associated with the disease, the team has now identified a protein implicated in the progression of the disease that appears highly regulated by the circadian rhythm, helping them join the dots and providing a potential new therapeutic target.

Syzygy, anyone?


Wikipedia defines a syzygy as "a roughly straight-line configuration of three or more celestial bodies in a gravitational system". On the 21st of December, as viewed from Earth, Jupiter and Saturn "will appear closer to one another and brighter than they have in 800 years in an event known as a “great conjunction”.

When they appear this close together, it's because they're in a Saturn-Jupiter-Earth straight line - a syzygy. Interestingly, if you're on Saturn (or, in fact, in orbit, as it's a gas giant), Jupiter and Earth will appear close together. If you're near Jupiter, nothing special appears to be happening - you'd have to be on one side of Jupiter to see Saturn and on the other to see Earth.

So, there you have it. We're going to be part of a syzygy. And I'm sure I can't be the only person to use this term in relation to the coming "great conjunction", though I haven't seen it elsewhere.

A palm oil alternative could help save rainforests | BBC News

There's an ugly truth to the beauty products we slap on our faces and an unsavoury truth to the foods we eat: many are made with palm oil, which is responsible for the rapid deforestation of some of the world's most biodiverse forests, destroying the habitat of already endangered species like the orangutan, pygmy elephant and Sumatran rhino.
But now the biotech industry says it has come up with a solution - a synthetic alternative that doesn't involve burning down or clearing any rainforest. It says this could eventually replace natural palm oil in everything from shampoos, soaps, detergents and lipsticks, to food products like packaged bread, biscuits, margarine, ice cream and chocolate.

'Autoantibodies' may be driving severe Covid cases, study shows | Science | The Guardian

Dramatic levels of “friendly fire” from the immune system may drive severe Covid-19 disease and leave patients with “long Covid” – when medical problems persist for a significant time after the virus has been beaten – scientists have said.
Researchers at Yale University found that Covid-19 patients had large numbers of misguided antibodies in their blood that targeted the organs, tissues and the immune system itself, rather than fighting off the invading virus.

Drug Reverses Age-Related Mental Decline Within Days | UC San Francisco

Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study by UC San Francisco scientists. The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after traumatic brain injury (TBI), reverse cognitive impairments in Down Syndrome, prevent noise-related hearing loss, fight certain types of prostate cancer, and even enhance cognition in healthy animals.
