Microbiomes Explained Simply

As many of you know, my science training centered around biology and more specifically, microbiology. Microorganisms fascinated me the first time I looked in a microscope and my interest continues today in the form of microbiome research and the even smaller natural realms of nanoscience and nanotechnology. 

So you can imagine my excitement to find a new video,  The Hidden World of Microbiomes, by scientist, founder of PhD Comics, and illustrator, Jorge Cham, Ph.D. If you have never seen Jorge's science cartoons and videos, you are in for a science treat. They are simple to understand, brief, and fun!

I'll be revisiting my favorite videos/animations about science and exploration during these hot summer days on the YouTube PhD TV channel. Stay cool and Go Science!

Asteroid Day

I was out-of-town for the celebration, but just to catch up, June 30th was designated as Asteroid Day. It was created in 2015 to "bring together scientists, artists and concerned citizens to raise awareness of the hazards of asteroid impacts and build support for solutions that might avert disaster from the skies."

Museums and science centers around the globe host a ton of events and use the associated publicity to highlight STEM (science, technology, engineering, and mathematics) and art events concerning the Earth and environment.

The June date aligns with the 40 meter wide asteroid that hit Tunguska, Siberia in 1908 and leveled 2,000 km of forest. The energy released has been estimated at 185 times that of the atomic bomb at Hiroshima. Not trivial, but by comparison Krakatoa's 1883 eruptions (4 over four hours) were so loud, they could be heard 3,000 miles away in Perth, Australia. The final blast was 10,000 times more powerful than the one unleashed by the atom bomb dropped on Hiroshima. 

So, fingers crossed, only asteroids of the smaller, gentler kind will feel the gravitational tug to visit Earth anytime soon. In the meantime, we will keep working on ways to dissuade them and their larger cousins. Go science!
