Since the 1960s, antioxidant supplements have been promoted as a miracle cure and that has never been true - preventing oxidation too much would be as bad as not preventing enough - but luckily few supplements make coenzyme Q bioavailable at all. Evolution created a way for the energy factories of our cells, mitochondria, to be thrown out of balance by pills.

Yet they can be thrown out of balance by nature. Coenzyme Q is entirely natural, and a lack of it leads to mitochondrial diseases like Leigh syndrome. But short of experimentally replacing mitochondrial DNA, it is hard to modify. For anything to change it must pass through the watery cell interior called cytoplasm to the surface of the cells in order to neutralize oxidized lipid species. 

The booster dose of either the BNT162b2 mRNA (Fosun-BioNTech, equivalent to Pfizer-BioNTech outside China) or CoronaVac (Sinovac) COVID-19 vaccine was correlated to a 90 percent reduction in death in people with multiple co-morbidities compared to 2 doses, according to a new study.

Reducing the risk of transfusion-transmitted HIV from blood donations is important for public health and the U.S. currently uses time-based deferrals to assess donor eligibility. Now the FDA is proposing individual risk-based questions to reduce the risk of transfusion-transmitted HIV similar to policies in place in countries like the United Kingdom and Canada.

Blood donations are important and FDA believes the implementation of the proposed individual risk-based questions will not compromise the safety or availability of the blood supply. The new draft recommendations are based on data from other countries with similar HIV epidemiology that have instituted this approach, as well as ongoing surveillance of the U.S. blood supply.

Food is not medicine, anyone claiming it is medicine is selling you something, like a diet plan, but nutrients can impact cancer cells.

How that applies consistently is unknown so a new tool hopes to create an exploratory method using mice. Mice don't translate well to humans, they are not little people, but they can exclude effects in humans and that has value also. 

Sudden infant death syndrome (SIDS) is a diagnosis of exclusion, a general term for death during the first year of life that lacks an obvious cause.

Though it is a leading cause of death, its etiology is complex and remains largely unknown so assumptions are things like sleeping in a dangerous position, a general failure during the critical development period, or an unknown underlying biological vulnerability.

Many parents say they are worried about the negative effects of screen time on children. Too much of anything can have negative effects, from books to music to TV, but the solution is to impose diversity so they eventually enjoy different activities.

The screen time problem got even worse due to government lockdowns imposed during the COVID-19 pandemic. Rather than wear masks in a park, it generally led to more screen time and less outdoor time for children.
