Heart inflammation after a COVID-19 vaccine is very rare but epidemiology exists to vreate exploratory between products and outcomes and a recent analysis showed incidence of myocarditis, pericarditis or myopericarditis is two- to threefold higher after a second dose of the Moderna Spikevax COVID-19 vaccine compared to the Pfizer BioNTech COVID-19 vaccine.

That's not a reason to avoid a vaccine, any more than you should stop eating salad if it has a regular pesticide rather than an organic one, but it may mean that it's beneficial to choose specific vaccines for certain populations.

A faint white dwarf star as well as the remains of its orbiting planetary system are over ten billion years old, according to a new estimate.

WDJ2147-4035 is the oldest dead star with an evolved planetary system found to-date.

A white dwarf is a star that has burnt up all of its fuel and shed its outer layers and is now undergoing a process of shrinking and cooling. During this process, any orbiting planets will be disrupted and in some cases destroyed, with their debris left to accrete onto the surface of the white dwarf.

Virtual Reality devices are advertised everywhere but have as much uptake as USDA nutrition guidelines or 3-D televisions. One reason is that it's a lot of money for something you can use for 20 minutes without fatigue. Another is VR sickness, a type of motion sickness which comes from users seeing “motion” through their headsets without actually moving. The symptoms include headaches, nausea, and sometimes vomiting. 

At about this time of the year I find myself teaching my students about the construction of V-A theory, which is a milestone in the construction of the Standard Model of particle physics. And in so doing I rejoice about having a chance to tell them the details of one of the most brilliant experiments of the twentieth century, one performed in 1957 by Maurice Goldhaber with his colleagues Grodzins and Sunjar, and which has become a cornerstone of the physics of weak interactions and of particle physics in general. 

Researchers from the U.S.

Neuroscience is still in its infancy, despite claims by people using fMRI to suggest links between lots of things, but a few things are established, like that fear 'resides' in the amygdala.

Linking that same part of the brain to obesity in mice, and therefore humans, in a new paper warrants more skepticism. Mice are, as famously stated when science was science, not tiny people. We do have things in common with mice, just like we share 60% of our DNA with bananas, but no one suggests their study on bananas has 'implications' for humans the way every trial lawyer running a grift and wanting to sue an agriculture company suggests about mouse models.

When the federal government took over health care during the Obama years, a lot of promises were made while the concern when legislation was passed without knowing which parts of three competing plans would be implemented boiled down to high cost to get a million people insured who couldn't get insurance.

It ended up being worse than projected. Individual plans shot up 300% in just a few years and may never be affordable again. There are two big reasons the system is flawed, and they are why up to 40% of people will abandon their political party if a candidate on the other side says they want to fix the high cost of health care.(1)

A recently published study in a high-profile medical journal appeared to call into question the efficacy of colonoscopy, a proven and widely utilized strategy for the screening and prevention of colorectal cancer.

A metabolite that converts white fat cells (sometimes called “bad” fat) to brown fat (“good” fat) cells could lead to treatment metabolic conditions like cardiovascular disease plus lifestyle-preventable things like type 2 diabetes.

Obesity is best treated by caloric reduction and energy intake but it wouldn't exist at all if everyone could maintain energy homeostasis that easily, and obesity is fast closing on smoking as the top lifestyle disease killer in the world. Regardless of why diseases happen, with health care controlled by government a leaky bucket has become a leaky water tower, so more ways to prevent disease will keep people out of emergency rooms - and that is where everyone goes because a doctor visit can't happen for a month.
