Researchers have found what can cause Lupus in children. From the article:

Sometimes a single mutation in our genetic make-up is enough to cause disease. This is also the case with the autoimmune disease lupus. Lupus causes severe inflammation throughout the body and can have a serious impact on the lives of those affected. Researchers at the Max Planck Institute for Infection Biology in Berlin have now discovered a mechanism that can trigger lupus in children. This mechanism regulates the amount of a specific immune receptor that normally recognizes the genetic material of pathogens. If this mechanism is disrupted, receptors accumulate in the immune cells leading to the recognition of the body's own genetic material. As a result, the immune system turns against its own body and causes the systemic inflammation of lupus.

Our long national nightmare is over. Researchers have determined an enzyme is responsible for making our urine yellow.

From the article:

Gut microbes encode the enzyme bilirubin reductase that converts bilirubin into a colorless byproduct called urobilinogen," explained Hall, who has a joint appointment in the University of Maryland Institute for Advanced Computer Studies. "Urobilinogen then spontaneously degrades into a molecule called urobilin, which is responsible for the yellow color we are all familiar with.

Well this is some good news. Via the article:

We saw various abnormalities in the muscle tissue of the patients. At the cellular level, we saw that the mitochondria of the muscle, also known as the energy factories of the cell, function less well and that they produce less energy," says Rob Wüst, Assistant Professor at Department of Human Movement Sciences at the VU University. "So, the cause of the fatigue is really biological. The brain needs energy to think. Muscles need energy to move. This discovery means we can now start to research an appropriate treatment for those with long-COVID

WELL deserved I might add.

Well I shall not lie, this is disturbing.

It was a fairly regular day on the ward for Canberra hospital infectious diseases physician Dr Sanjaya Senanayake, until a neurosurgeon colleague called him and said: “Oh my God, you wouldn’t believe what I just found in this lady’s brain – and it’s alive and wriggling.”

The neurosurgeon, Dr Hari Priya Bandi, had pulled an 8cm-long parasitic roundworm from her patient, prompting her to call on Senanayake and other hospital colleagues for advice about what to do next.
