François Kouamé, preso número 67, muestra con orgullo su cerda y sus cuatro cerditos. Con botas de goma, camina frente a dos nuevos tractores y se encamina feliz hacia un campo donde pronto comenzarán a crecer plantas de mandioca (yuca) y maíz. “Mira esos brotes, ¡es mucho trabajo!”, comentó en...

Exactly how animals separate the smells of objects of interest, such as food sources or the scent of predators, from background information has remained largely unknown. Even the extent to which animals can make such distinctions, and how differences between scents might affect the process were...

Rapid warming of the Atlantic Ocean, likely caused by global warming, has turbocharged Pacific Equatorial trade winds. This has caused eastern tropical Pacific cooling, amplified the Californian drought, accelerated sea level rise three times faster than the global average in the Western Pacific...

Researchers have developed a simple and versatile method for making artificial anti-cancer molecules that mimic the properties of one of the body’s natural defense systems. The chemists have been able to produce molecules that have a similar structure to peptides which are naturally produced in the...

In the August 2014 issue of LITHOSPHERE, Steve Israel of the Yukon Geological Survey and colleagues provide conclusions regarding the North American Cordillera that they say "are provocative in that they blur the definition of tectonic terranes, showing that many observations of early geologists can be attributed to evolving...

Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface. The new observations of the small-scale extremely hot temperatures are consistent with only one current theory: something called nanoflares -- a...
