Mesa Verde’s ‘Mummy Lake’ Was Built to Hold Rituals, Not Water, Study Says

by Blake de Pastino in Western Digs

A grand, sandstone-walled pit in Mesa Verde National Park has for decades been seen as an achievement of prehistoric hydrology, part of a system of cisterns and canals used by Ancestral Puebloans to harvest rainwater on the arid plateau as much as 1,100 years ago.

Strange Insects Taste

by Mark Lasbury in As Many Exceptions As Rules

New research is describing the ways that arthropods use gustatory receptors. Drosophila use a muscular reflex to extend or retract the proboscis, based on the sweet or bitter taste they experience. In silica studies are showing that female behaviors are driving gene duplication and evolution of taste receptor genes, while specific taste receptors are responsible for male female interactions in fruit fly courtship rituals.

Lithium-Ion Batteries Get A Boost

by Whitney Campbell in Green Screen

After lithium-ion batteries were introduced to the public in the early 1990s, they've charged all kinds of products, from handheld cell phones to jumbo airplanes. But as their prevalence has grown, so have concerns with their safety.

In January 2013, airlines had to ground their fleets of Boeing Dreamliners due to fires linked to the "thermal runaway" of lithium-ion batteries. Likewise, lithium-ion-powered cars, such as the Tesla Model S, have caught fire "20 or so [times]........ Read more »

A Parched Future: Global Land and Water Grabbing

by Jalees Rehman in Fragments of Truth

Land grabbing refers to the large-scale acquisition of comparatively inexpensive agricultural land in foreign countries by foreign governments or corporations. In most cases, the acquired land is located in under-developed countries in Africa, Asia or South America, while the grabbers are investment funds based in Europe, North America and the Middle East. The acquisition can take the form of an outright purchase or a long-term-lease, ranging from 25 to 99 years, that gives the grabbing entity e........ Read more »
