Oxford University researchers have started testing inhaled versions of their COVID-19 vaccines compared to those given by intramuscular injection (Associated Press, Sept 14, 2020). An inhaled vaccine could be more effective than those given by injection because it may cause a stronger local immunity in the throat and nose, which are the primary entryways for the virus.
A positive outcome of the many COVID-19 restrictions has been a huge boom in bicycling. If you are a regular cyclist or are new to the sport, be proud. Humans riding on bicycles are more energy-efficient than any other form of transportation and any other animal. Vance Tucker of Duke University compared bicyclists to people and animals running, birds flying and fish swimming, as well as to people in motor-powered cars, boats, trains and planes
Extensive research by Dr. Ajit Varki at UC/San Diego suggest that 2-3 million years ago, our pre-human ancestors had a single genetic mutation that could explain why humans can outrun their primate relatives.
Many of you think that Jonas Salk and Albert Sabin stopped the polio epidemics with their killed polio Salk vaccine or the live and weakened Sabin polio vaccines. However, you don’t see polio anymore primarily because of Joseph Melnick, who supervised the field trials of the vaccines and made sure that most of the entire American population was vaccinated against polio.
Vitamin D deficiency increases risk for becoming infected with COVID-19, and for complications and death from the disease.
A study of 500 patients showed that those who had low blood levels of hydroxy vitamin D were twice as likely as those with normal levels to develop COVID-19.
A recent review of 22 scientific studies shows that adding a resistance program such as lifting weights to endurance sports such as running or cycling can increase muscle size and strength, with greater benefit from low volume, high-resistance weight lifting than high volume, lower-resistance exercise.
Chadwick Boseman was a movie actor who brilliantly portrayed baseball player Jackie Robinson (2013), singer James Brown (2014), and Supreme Court Justice Thurgood Marshall (2017). In 2016, at age 40, he was diagnosed with colon cancer and never told the public about his serious diagnosis.
In the largest study so far of accelerometer-measured physical activity, 96,476 healthy men and women in Great Britain (mean age 62 years) wore wrist accelerometers for one week and were then followed for an average of 3.1 years. The people who were more active had a lower risk of dying, and adding intensity to their exercise increased that protection.
A study of 20 healthy, normal-weight people found that changing their evening meal from 6PM to 10PM significantly increased their markers for becoming obese and developing diabetes.
Fuller Albright discovered more new diseases and their causes than any other person in the history of medicine. He founded modern endocrinology, the study...
