I'm not saying its aliens, and I figure it's for some mundane purpose such as trapping seafood, but I enjoyed watching this helicopter-shot video of mysterious beach circles near Isla Aguada in Mexico. Nothing similar is evident on Google Earth. I'm not saying it's aliens. Read the rest

Ship's captains and outside monitoring firms have reported waves of GPS jamming around Shanghai's ports, on a scale and of a severity never seen before: the jamming causes ships' locations to be incorrectly displayed and to jump around; the observations were confirmed via an anonymized (sic) data-set from a short-hire bike firm, whose bikes are also mysteriously appearing and disappearing at locations all through the region. The spoofing has created a massive local shipping hazard and has led to spectacular shipwrecks. Read the rest

This NASA photo taken from the International Space Station shows crop circles in southwest Egypt's Sahara Desert. The crops thrive in the middle of the desert thanks to either secret alien technology or the amazing underground Nubian Sandstone Aquifer System that covers two million square kilometers. From the NASA Earth Observatory:

The crop circles are a result of center-pivot irrigation, an efficient method for water conservation in agriculture. Groundwater from the Nubian aquifer is drawn up from wells in the center of the circles, and it is sprayed or dripped out of long, rotating pipes that pivot around the center.

Most of the crops pictured here are likely potatoes (darker green circles), wheat (lighter brown circles), or medicinal and aromatic plants such as chamomile. The light, tan-colored crop circles likely have undergone controlled burning to remove excess plant matter and essentially clean up the land for the next crop.
