Hello science fans,
I realize the current situation is unsettling so let me recommend Steven Pinker’s Enlightenment Now to put things in an historic and less grim perspective. Please continue supporting science and extending your circle of compassion.
On Saturday July 27th, 27 wonderful volunteers presented an all-day science event, the Billion Year Walk around Oakland’s Lake Merritt. With enough support, it will become an annual event. Check out some of the photos.
There was a live demonstration of photosynthesis at the Billion Year Walk and coincidentally, photosynthesis is in the news: cyanobacteria may have achieved oxygen-generating photosynthesis earlier than thought, possibly as early as 3.5 billion years ago. It was perhaps a billion years ago when a cyanobacterium was engulfed by a eukaryote, creating the first chloroplast.
NASA’s Transiting Exoplanet Survey Satellite (TESS) continues to locate planets in other star systems. (“Solar System” only refers to the collection of astronomical objects associated with our Sun, aka Sol.) One recently discovered planet, GJ 357 d, is potentially habitable and a ‘mere’ 31 light years away. GJ 357 d orbits its dim sun in only 51 of our days; meaning that i would be over 400 years old by that planet’s calendar!
Hmmm. ¿Why is it that we humans don’t live 400+ Earth years? There are far too many aspects to aging than i could list here, and a new detail has just been announced: senescent cells stop producing DNA to protect us from cancers. Here is a video on the research. ¿Will humans eventually enjoy healthy lives for hundreds of years? Don’t bet against it but perhaps extreme longevity may lead to overcrowding which could trigger famines and political unrest. It could also exacerbate the division between the Haves and the Have-Nots since only the wealthiest will be able to afford life-extension treatments – at least initially.
Set your alarm for 8:40 pm Tuesday. That will give you two minutes to get to a place where you can have a clear view of the sky to see the International Space Station pass over almost directly overhead. On board are Christina Koch (electrical engineer, U.S.), Alexey Ovchinin (pilot, Russia), Nick Hague (astronautical engineer, U.S.), Luca Parmitano (pilot, Italy), Alexander Skvortsov (pilot, Russia), Andrew Morgan (physician, U.S.). One of their projects is on creating living organs in zero G.
Fortunately for us, the explOratorium’s Museum of the Moon has been extended to September 2nd. Very impressive and enjoyable.
