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.Metal Powders as Recyclable Fuel

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?

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.
This new tech could be game-changing for wearables.gizmodo.com
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.#science #medicine #health #cancer

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.”#science #medicine #health #Covid-19 #CoronaVirus #pandemic
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.

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

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.#science #medicine #health #Covid-19 #CoronaVirus #pandemic
U.S. government scientists studied the brains of 19 people who died after contracting covid-19.gizmodo.com
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.

It ignores a number of crucial facts.But it does show that a lot of younger, fitter people, the thousands who have protested in London, for example, seriously undervalue people who are older or less healthy.

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.#science #medicine #health #Covid-19 #CoronaVirus #pandemic
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.#science #medicine #health #dementia #Alzheimers

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.#science #environment #GlobalWarming #ClimateChange #ClimateCrisis #ClimateBreakdown #PalmOil
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.
Plantations for palm oil are blamed for rainforest destruction, but an artificial palm oil is close.www.bbc.co.uk

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.
