2019-10-11: Comet seen over northeast China

A suspected falling meteorite was caught on tape in many places in northeast China on October 11. The suspected meteorite fell in just a few seconds and illuminated the night sky:

Opportunity to evaluate an AI Tool : The Blue Dot Algorithm.

January 9, 2020

On January 9, the World Health Organization notified the public of a flu-like outbreak in China: a cluster of pneumonia cases had been reported in Wuhan, possibly from vendors’ exposure to live animals at the Huanan Seafood Market. The US Centers for Disease Control and Prevention had gotten the word out a few days earlier, on January 6.


But a Canadian health monitoring platform, the Blue Dot, had beaten them both to the punch, sending word of the outbreak to its customers on December 31, 2019.

Herpes viruses reactivated

“The herpes viruses were reactivated in more than half of the crew aboard Space Shuttle and International Space Station (ISS) missions.

“NASA astronauts endure weeks or even months exposed to microgravity and cosmic radiation – not to mention the extreme G forces of take-off and re-entry,” said senior author Dr. Satish K. Mehta of KBR Wyle at the Johnson Space Center.

“This physical challenge is compounded by more familiar stressors like social separation, confinement and an altered sleep-wake cycle.”

Mehta and colleagues monitor the physiological impact of spaceflight by analyzing saliva, blood and urine samples from the astronauts. What they found was problematic.

“During spaceflight there is a rise in secretion of stress hormones like cortisol and adrenaline, which are known to suppress the immune system. In keeping with this, we find that astronaut’s immune cells – particularly those that normally suppress and eliminate viruses – become less effective during spaceflight and sometimes for up to 60 days after.”

These circumstances could be further compounded by the stressful environment the astronauts find themselves in.

“To date, 47 out of 89 (53%) astronauts on short space shuttle flights, and 14 out of 23 (61%) on longer ISS missions shed herpes viruses in their saliva or urine samples,” reported Mehta.

“These frequencies – as well as the quantity – of viral shedding are markedly higher than in samples from before or after flight, or from matched healthy controls.”
