— However, observations do not fall into territory of harm, according to exercise physiologistsSmall physiological changes can result from wearing an N95 mask all day, including during light exercise, a small trial found. Whether this has practical implications for mask users is unclear, however, as exercise physiologists said they were not convinced by the data. Compared with unmasked controls, 15 young healthy volunteers randomized to wear an N95 mask for 14 hours (from 8 a.m. to 10 p.m.) in a metabolic chamber had a reduced respiration rate and lower oxygen saturation by pulse oximetry within the first hour, while...

t was all part of the People’s Liberation Army’s (PLA) biowarfare plan against the United States. The design of COVID-19 was based on a number of bioweapon features, in particular, highly contagious, low lethality, and a high rate of asymptomatic transmission. Another important feature of a PLA bioweapon, not mentioned on that list, is disguising its origin. That is, the capability of avoiding responsibility for a biowarfare attack by designing a virus that could be blamed on a natural outbreak. Changjun Wang, a high ranking officer in the PLA’s Eastern Theater Command headquartered in Nanjing, was responsible for the isolation...

Peter Ben Emerek of the World Health Organization (WHO) proclaims it “extremely unlikely” that the coronavirus causing COVID-19 leaked from China’s Wuhan Institute of Virology (WIV). According to the WHO, the issue warrants no further study. But evidence is emerging that the Wuhan lab deliberately engineered the virus. The story begins in Canada. This month Canada removed Dr. Xiangguo Qiu, a virologist from Tianjin, China, and her husband, Keding Cheng, from the nation’s Public Health Agency because, as Karen Pauls of the Canadian Broadcasting Corporation (CBC) reported on February 6, the pair had previously been removed from Canada’s National Microbiology...

Just like a comic book super hero, you could say that the enzyme superoxide dismutase (SOD1) has a secret identity. Since its discovery in 1969, scientists believed SOD1's only role was to protect living cells against damage from free radicals. Now, researchers at the Johns Hopkins Bloomberg School of Public Health have discovered that SOD1 protects cells by regulating cell energy and metabolism. The results of their research were published January 17, 2013, in the journal Cell. Transforming oxygen to energy for growth is key to life for all living cells, which happens either through respiration or fermentation. When oxygen...
