Researchers from the University of Exeter created an experiment to help further their research into the transmission of lungworm from snails to dogs. They tagged hundreds of snails with LEDs and UV paint and tracked their movement at night.
Oldest Globe with New World Discovered on Ostrich Egg
A globe engraved on an ostrich egg, dated from 1504, has emerged as most likely the oldest known globe to include the New World. A photo released from the Wisconsin Historical Museum shows a 1513 map of the world (picture 2), considered one of the earliest printed maps to show the New World is dated 9 years later than the “ostrich egg globe.”.
The “egg globe” shows a scattering of islands in North America’s position, 12 years after Columbus’s first voyage, the area was still largely unknown. Europe, North Africa and the Middle East are meticulously engraved on the egg globe.
On the globe’s depiction of the Western Hemisphere, the large land mass is South America, better known at the time from the voyages of the earliest European explorers than North America. On the globe, the New World bears three labels: “TERRA DE BRAZIL,” “MVNDVS NOVVS” and “TERRA SANCTAE CRVCIS.”
The globe, when pictured other ostrich eggs, is about the size of a grapefruit. The globe is actually the connected bottom halves of two eggs, which explains why the “globe” egg in not oval-shaped like the other ostrich eggs.
Stefaan Missinne, a collector who wrote an analysis of the “ostrich egg globe” for the Washington Map Society, speculates that the globe may have connections to Leonardo da Vinci’s workshop. But the maker remains unknown.
Frilled Shark (Chlamydoselachus anguineus)
The frilled shark is a primitive species that is seldom encountered alive.
The shark’s long, flexible jaw is able to to gape extremely wide, allowing the fish to swallow prey over half its size. Rows of sharp teeth prevent captured prey from escaping.
The frilled shark has a speculated gestation period of 3.5 years, the longest of any vertebrate.
Cuttlefish? More like cutiefish.
They are the cutest animal alive..

SAM DROEGE | USGS Bee Inventory and Monitoring
Sam Droege - The USGS Native Bee Inventory and Monitoring Program designs and develops large and small scale surveys for native bees. As part of that program we also develop identification tools and keys for native bee species. One aspect of creating those tools is creating accurate and detailed pictures of native bees and the plants and insects they interact with. Photos were taken with a system developed by Dr. Anthony G Gutierrez and taken by Brooke Alexander, Sue Boo, Heagan Ahmed and Sierra Williams.
Carrying Earthly greetings on a gold plated phonograph record and still-operational scientific instruments, NASA’s Voyager 1 has traveled farther from Earth than any other human-made object. And now, these researchers say, it has begun the first exploration of our galaxy beyond the Sun’s influence.
