A 2015 study tested eight commercial mosquito repellents, two fragrances and a vitamin B patch by releasing mosquitoes into a sealed chamber with a treated hand. The study found that after four hours, the most effective were products containing DEET, as well as one “natural” DEET-free spray… a product containing lemon eucalyptus oil was about as effective and as long lasting as products containing DEET.

France is paving more than 600 miles of road with solar (Smithsonian)
Last week, France’s minister of Ecology and Energy announced that the country will pave 621 miles of road with solar panels over the next five years, with the goal of providing cheap, renewable energy to five million people. Called "the Wattway," the roads will be built in collaboration with the French road-building company Colas and the National Institute of Solar Energy. The company spent the last five years developing solar panels that are only about a quarter of an inch thick and are hardy enough to stand up to heavy highway traffic without breaking or making the roads more slippery...they can be installed directly on top of existing roadways, making them relatively cheap and easy to install without having to tear up any infrastructure.
The announcement comes just weeks after a woman sued Twitter, saying the platform knowingly let ISIS use the network "to spread propaganda, raise money and attract recruits."

New research shows that large earthquakes on one fault could jump to another causing widespread damage. / That finding isn't new, but the researchers who published the paper said they found a quake where the first temblor sparked another more than 30 miles away. University of California Riverside researcher Gareth Funning said this cascading effect could mean more widespread damage when a large quake hits.
