Picky Eaters: Bumble Bees prefer plans with nutrient-rich pollen – The protein to lipid ratio makes a difference to bumble bees!

Ocean Acidification and Chemical Signaling – How ocean acidification impacts chemical signally of shell fish…an infographic about research on peptides that are involved in detecting predators, homing, and reproduction.

How one of history’s bloodiest wars eventually saved lives – By the end of World War I, combatant deaths has reached 10 million. Twice as many were injured. Post-traumatic stress disorder was recognized for the first time – called ‘shell shock.’ Blood transfusion, oxygen and treatment on the front lines became the norm. See some of the devices developed and used during that time period in this post or at the Wooded exhibition at London’s Science Museum.

Floating Solar: A Win-Win for Drought Stricken Lakes in the US – Will this idea become reality? It seems that in places where water is scarce that reducing evaporation and producing power at the same time would be a positive thing.

Humans artificially drive evolution of new species – Human drive extinction but also speed up evolution of new species as well. For example – a common house mosquito has evolved into a new species that thrives in subterranean environments – like subway stations; it can no longer interbreed with its above ground ancestor species.

Beyond Sightseeing: You’ll Love the Sound of America’s Best Parks – A project to record the (non-human) sounds of national parks.

Vanishing Act: Why Insects are declining and why it matters – Another example of the importance of biodiversity to our future…and the future of the planet.
