Friends Don’t Let Friends Walk and Text
After 23 pedestrian accidents, including three fatalities, the town of Fort Lee, New Jersey is imposing a fine on people who engage in “dangerous walking”, which includes texting while crossing the street.

Earliest Record of Pollination Dates Back to the Dinosaur Era
In Northern Spain, scientists have uncovered the remains of 100 million year old insects dusted with pollen grains, making this find the earliest known evidence for pollination. This discovery is “the only one from the age of the dinosaurs” and sheds light on “the great evolutionary success story” that is the co-evolution of flowering plants and insects, according to study researcher Carmen Soriano. 

How to Watch SpaceX’s Historic Launch to the ISS
This Saturday, May 19th, SpaceX is scheduled to launch its unmanned Dragon capsule to the International Space Station. This historic mission marks the first time a commercially built spacecraft will make contact with an orbiting outpost. Both SpaceX and NASA will stream live footage of the launch on their websites, as well as live coverage of its flyby, docking, and entry to the ISS on flight days 3, 4, and 5. 

All of Earth’s Water in a Single Drop
The top image is an illustration of what all the Earth’s water would look like if it was condensed into one drop. It looks tiny, but the drop in the image has a diameter of about 860 miles, and a volume of 332.5 million cubic miles.  However, 96% of the Earth’s water is saline water, which is undrinkable, and this picture is a good reminder of how precious a resource water is.
