Life amid acidity near a smoldering part of the Arctic
by Rosin Cerate in Rosin Cerate
Way, way up in northwestern Canada (on the lower east side of Cape Bathurst, Northwest Territories), where the mainland meets the Arctic Ocean, a 30 km stretch of seacoast has been smoldering away for hundreds if not thousands of years.The Smoking Hills, named by the explorer John Franklin during one of his early 19th century expeditions to the Canadian Arctic, consist of shale bedrock covered by several meters worth of soil and loose rocks deposited by ancient glaciers and rivers. The land fall........ Read more »

Baby Giant Squids
by Dr. M in Deep Sea News
We know almost nothing about Giant Squids with mantles lengths less than 1000 mm (~40 inches). Very young squids are even more enigmatic than adults. A recent study reports the collection of three very young Giant Squids off the Japanese coast. The three young measured 140.8, 332, and 332 mm (5.5 and 13 inches). The heaviest of […]... Read more »

I Pity the Species That Doesn’t Decorate

Mr. T made mohawks and fool pitying a life goal for many. Another life goal for many, thanks to first name Mr, middle name period, last name T, was decorating themselves with enough gold chains to crash a third-world economy. Although humans are the only species where decoration functions strongly in social interactions (see Beyonce), […]... Read more »

Missing link in the evolution of complex cells discovered
by Perikis Livas in Chilon
In a new study, published in Nature this week, a research team led from Uppsala University in Sweden presents the discovery of a new microbe that represents a missing link in the evolution of complex life. The study provides a new understanding of how, billions of years ago, the complex cell types that comprise plants, fungi, but also animals and humans, evolved from simple microbes.

Robot Discovers Two New Neighbors
by Perikis Livas in Chilon
Maunakea, Hawaii – A team of astronomers using ground-based telescopes in Hawaii, California, and Arizona recently discovered a planetary system orbiting a nearby star that is only 54 light-years away. All three planets orbit their star at a distance closer than Mercury orbits the sun, completing their orbits in just 5, 15, and 24 days. The paper is being published in the Astrophysical Journal....

Major Advance in Artificial Photosynthesis
by Perikis Livas in Chilon
A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels....
