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. 

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.

Patients with myocarditis can experience chest pains, shortness of breath or an irregular heartbeat. In severe cases, the inflammation can lead to heart failure and death.

In some instances, primarily with teenage boys, myocarditis is one of the complications associated with mRNA COVID-19 vaccination. A new study shows that if it is likely to happen, it is a far worse risk actually getting the SARS-CoV-2 infection. 

It's become postmodernism to state that there isn't much difference between women and men but that is by people who conflate gender with biology. Scientifically, there are vast differences, to such an extent that there is worry about clinical trials because not enough women are included.

Some things that are considered potential stereotypes, men are slightly better at math, women are better at language, also get critical examination regarding differences in cognitive abilities and what the underlying brain mechanisms might be. 

It used to be common for physicians to give common-sense advice to patients; lose weight, drink less alcohol, stop smoking.

Such shaming may reflect an unequal power relationship, according to a paper in Humanities and Social Sciences Communications which also argues that such shame may create a barrier to accessing services, a fear of being judged, circumstances, coping behaviors, body, illnesses, along with other vulnerabilities.
