POPSConcrete that literally eats pollution. If it works, then this could be a big breakthrough indeed. However, it's not like cities are going to start re-paving roads that don't need it, or demoing & rebuilding building, (or even just repainting them with this solution)... The cost would be prohibitive. So that 50% savings (just off of 15% of concrete surfaces) is a LONG way away. Plus, this definitely doesn't curb the need for changing the way we pollute...

POPSWhy Are Humans Different From All Other Apes? It’s the Cooking, Stupid This is a fascinating and quite fresh view on a possibly groundbreaking view on the evolution of the human specie. “Cooked food does many familiar things,” he observes. “It makes our food safer, creates rich and delicious tastes and reduces spoilage. Heating can allow us to open, cut or mash tough foods. But none of these advantages is as important as a little-appreciated aspect: cooking increases the amount of energy our bodies obtain from food.” (emphasis mine)

POPSCULTURAL EVOLUTION We are finally starting to understand the patterns of culture change and the role of natural selection in shaping them. And since everything from weapons of mass destruction to global heating are the results of changes in human culture over time, acquiring a fundamental understanding of cultural evolution just might be the key to saving civilization from itself.

POPS21 Excuses for not Having Sex — You can’t stop thinking about all the stuff you have to do tomorrow, and what you really want to do is find a pencil and a piece of paper. — You have your teeth-whitening equipment in. — You are bloody tired. — You have hiccups. — He hasn’t shaved. — You think the heating might still be on. It is unbelievably hot. — It is too cold to risk the duvet moving at all.

POPSThe End of Everything End of Cosmology – 3 trillion years from now. End of Stars – 100 trillion years from now. The End of Regular Matter – 10 to the power of 30 years from now. End of Black Holes – 10 to the power of 100 years from now. The End of Everything – 10 to the power of 100 years and beyond. Perhaps there will be another Big Bang someday. Perhaps the Universe is cyclical and the whole process will start up again. Perhaps it won't, and this bleak future of a cold, dead Universe is all that awaits us. It's not happy, but it's awe inspiring to consider the long future ahead, and helps us appreciate the vibrant age we live in today.

POPSLet's get real about alternative energy The public discussion of energy options tends to be emotional, polarized, mistrustful and destructive. I hope that focusing attention on the numbers may make it possible to develop honest and constructive conversations about energy.

POPSNanotechnology: Entirely New Way Of Storing Gas Created The transition happens quickly and is controlled simply by heating the material to close the nanovalves, then adding water to the substance to re-open them and release the trapped gas. The paper includes video footage of the process taking place under a microscope, showing gas bubbles escaping from the crystals with the introduction of water. "The process is highly controllable and because we're not breaking any strong chemical bonds, the material is completely recyclable and can be used indefinitely," Shimizu said.
