Ah, summer, the time to neglect thinking and just build crap.  So, much as with the DIY Clean Room, I started gathering bits to make the DIY Vacuum chamber.

I'm building a vacuum chamber to make sure that my satellite doesn't go kablooey when it hits space. Vacuum is a nasty environment.  We have no pressure, we have outgassing, and (least we not forget) we have the simple removal of air.

Princeton scientists say they may have discovered the oldest fossils of animal bodies; sponge-like creatures that were living in ocean reefs 650 million years ago. The shelly fossils, found beneath a 635 million-year-old glacial deposit in South Australia, would represent the earliest evidence of animal body forms in the current fossil record by at least 70 million years.

Is attention deficit hyperactivity disorder (ADHD) too often confused with immaturity or just young age?  It may be, according to new research by a Michigan State University economist published in the Journal of Health Economics.

ADHD is the most commonly diagnosed behavioral disorder for kids in the United States, with at least 4.5 million diagnoses among children under age 18, according to the Centers for Disease Control and Prevention.

Science has a long history of being multinational and has long been a way to bridge cultures and balance the public good with private gain.    Science, being about excellence, has zero interest in race, creed or religion.  Maybe it has too much concern with politics and policies in some corners but even that is a minor blemish.  The fact is, cooperation works.

Cooperation comes naturally to science, as the big problems science is being called upon to address, like the future of energy, climate change and new pandemics, respect no boundaries. The days of science as a solitary thing are good.  Modern science at its best is now a group effort, inclusive and open.  Social even.
