These are some fantastic pictures. It makes me wonder why billionaires even have homes. If I had an insane amount of money, I'd be all over the world!
The mysterious “Relámpago del Catatumbo” (Catatumbo lightning) is a unique natural phenomenon in the world. Located on the mouth of the Catatumbo river at Lake Maracaibo (Venezuela), the phenomenon is a cloud-to-cloud lightning that forms a voltage arc more than five kilometre high during 140 to 160 nights a year, 10 hours a night, and as many as 280 times an hour.
What life might look like
Studying the co-evolution of photosynthesis with its atmosphere means we were trying to determine whether plants are smart enough to work out where the best places are to get radiation for photosynthesis. If we can figure out that they are smart enough, and if we can figure out what rules they use to choose the pigments for photosynthesis, we wondered if we could apply those rules to other planets around other stars. Could we use them to predict where the photosynthetic pigments are going to be, and what color these plants are going to be? A colleague of mine, Nancy Kiang, and a bunch of her biologist friends went through all of the literature and found every pigment life uses for photosynthesis on this planet. And by pigment, I mean a particular type of molecule that’s specifically tuned to take in a particular type of light and turn that into food for the plant.
They were surprised to find that people developed digestive problems when taking an antibiotic. The drug killed the "good" bacteria in the intestines as well as the "bad" bacteria that made them sick.
