Cold War spy satellite imagery reveals Ancient Roman forts      (via sciencedaily.com)     Original source 

A new study analyzing declassified Cold War satellite imagery reveals 396 previously undocumented Roman forts and reports that these forts were constructed from east to west, spanning from what is now western Syria to northwestern Iraq. The analysis refutes Father Antoine Poidebard's claim that the forts were located along a north-south axis.

Engineers develop breakthrough 'robot skin'      (via sciencedaily.com)     Original source 

Smart, stretchable and highly sensitive, a new soft sensor opens the door to a wide range of applications in robotics and prosthetics. When applied to the surface of a prosthetic arm or a robotic limb, the sensor skin provides touch sensitivity and dexterity, enabling tasks that can be difficult for machines such as picking up a piece of soft fruit. The sensor is also soft to the touch, like human skin, which helps make human interactions safer and more lifelike.

Raining cats and dogs: Global precipitation patterns a driver for animal diversity      (via sciencedaily.com)     Original source 

A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.

Fungal evolution discovered: Mycena can now invade living hosts      (via sciencedaily.com)     Original source 

Biologists have long known mushrooms of the genus Mycena, commonly known as bonnet mushrooms, as fungi that live off of dead trees and plants. New research demonstrates that bonnets can also find their ways into young, healthy trees and plants, where they try to cooperate. In doing so, they have made an evolutionary leap which challenges our understanding of the ecological roles of fungi.

Mummified mice discovered atop sky-high Andean volcanoes      (via sciencedaily.com)     Original source 

Scientists have uncovered 13 mummified cadavers of mice from the summits of Andean volcanoes that stretch nearly 4 miles above sea level. Analyses of the mummies, combined with the capture of live specimens, suggest that the mice scaled the Mars-like peaks on their own -- and are somehow managing to live on them.

The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs.

The encounter between Neanderthals and Sapiens as told by their genomes      (via sciencedaily.com)     Original source 

About 40,000 years ago, Neanderthals, who had lived for hundreds of thousands of years in the western part of the Eurasian continent, gave way to Homo sapiens, who had arrived from Africa. This replacement was not sudden, and the two species coexisted for a few millennia, resulting in the integration of Neanderthal DNA into the genome of Sapiens. Researchers have analyzed the distribution of the portion of DNA inherited from Neanderthals in the genomes of humans (Homo sapiens) over the last 40,000 years. These statistical analyses revealed subtle variations in time and geographical space.

Evolutionary secrets of 'Old Tom' and the killer whales of Eden revealed by genetic study      (via sciencedaily.com)     Original source 

Evolutionary biologists have for the first time decoded the genetic lineage of a famous killer whale and a pod that once worked alongside whale hunters off the coast of Australia. In the Australian tradition of claiming New Zealand's celebrities as its own, Old Tom, the leader of a pod of killer whales that famously helped whalers hunt baleen whales in the 20th century, has ancestral links to modern-day killer whales in New Zealand, according to new DNA research. Old Tom also shared a common ancestor with killer whales from Australasia, the North Pacific, and North Atlantic Oceans, but is most similar to modern New Zealand killer whales. However, most of Tom's DNA code is not found in other killer whales globally suggesting that the killer whales of Eden may have become extinct locally.
