Whenever I come across something cool in science (primarily in physics, biology, chemistry, astronomy), I will post it here. On a weekly basis, I read maybe a hundred articles on average so I can definitely post something cool, interesting, and possibly inspiring when I come across it. I am what you would call a science nerd! ;)
Feel free to post your own stuff and discuss anything science related. If you have any questions, don't hesitate.

SpaceX falcon9 rocket launch with on-board camera. It is a timelapse so speeds through it in 30 seconds. This is truly awesome to be able to reuse rockets. In past and presently, you can only use a rocket once before you have to trash it. SpaceX's falcon 9 rockets are reusable so you just have to refuel them, and they are ready to go.
The skeptical side of me says they need to show us the launch, refuel, and relaunch from start to finish. If it is as they say, it is expected cost of payload cost to drop from presently approximately $10,000 per pound to maybe $2,500-$3,000, which is MASSIVE savings!

Mars Rover stopping to take a selfie for his human buddies at home. How cute! More picture of Curiosity's backyard:

Huge advancement in medical science if we are able to successfully edit our DNA. Maybe thousands of diseases can be cured/treated with this technology. It will be very expensive and obviously has potential risks as your body develops immunity. You get 1 shot before you have to re-do it, and that could be very expensive if not impossible for certain complex diseases. www.nature.com/news/first-crispr-clinical-trial-gets-green-light-from-us-panel-1.20137

There is enough DNA in an average person’s body to stretch from the sun to Pluto and back — 17 times

The average person walks the equivalent of five times around the world in a lifetime.

Baby? We literally go through the evolutionary scale as our bodies develop. At one stage early on, we basically develop something that resembles gills. This is one of our many evidences for the mechanism of evolution in action. Our DNA has wrapped around itself over many millenia depending on the complexity of the organism it emanates from. I will find images tomorrow of the development cycle of a human baby. Been a while since I took biology

Lampz ready for some science lesson?? It is not really gills but resembles it. All it means is they share common ancestors. Creationists erroneously believe this means monkey turned into humans and wonder why are there still monkeys, but they don't understand the basics of evolution. The old species doesn't turn into new species like in Pokemon They just share common ancestor, which probably died out over time and diverged out into 2 different sub-species. Over millions of years, sub-species diverge out into 2 different species. Takes millions of years and tons & tons of generations before discernible changes even occur. Biologists incorrectly thought 100yrs ago that as an animal got more complex through evolution, the animal would just add a new stage during development to get more complex. It was proved to be wrong through further research. Even though there are many many similarities in the development cycle, it is not this straight forward like the image below shows. That image is faulty. Instead, Biologists now look at 'comparative embryology'.. as you can see, all babies are very similar in early stages of development. As they develop further, they become more and more complex, which is when their resemblances stop after early stage. These patterns show they share common ancestor somewhere in the past whatever number of millions of years ago.

Hyperloop explained. This future transport system will be significantly more fuel efficient than planes, significantly less pollution, and faster on average than most planes. There is also no waiting, air traffic to consider, and probably safer too.

“The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries... The size and age of the Cosmos are beyond ordinary human understanding. Lost somewhere between immensity and eternity is our tiny planetary home. In a cosmic perspective, most human concerns seem insignificant, even petty. And yet our species is young and curious and brave and shows much promise. In the last few millennia we have made the most astonishing and unexpected discoveries about the Cosmos and our place within it, explorations that are exhilarating to consider. They remind us that humans have evolved to wonder, that understanding is a joy, that knowledge is prerequisite to survival. I believe our future depends on how well we know this Cosmos in which we float like a mote of dust in the morning sky.” -Carl Sagan, astronomer

That is huge! We still need to figure out what to do with greenhouse gases like methane. Most of methane comes from overbreeding of animals like cows and pigs for meat. Maybe it is time to consume less meat on global basis. Methane is much more dangerous per tonne than co2, but there is obviously much more of co2. It is a good start to begin dropping the CO2 levels back to normal. Good find, buddy!
