Norwegian explorer Roald Amundsen became the first man to reach the South Pole in December of 1911. More than 100 years later, an international team of scientists led by Joe McConnell of Nevada's Desert Research Institute (DRI) have proven that air pollution from industrial activities arrived long before. Using data from 16 ice cores collected from widely spaced locations around the Antarctic continent, including the South Pole, McConnell's team created the most accurate and precise reconstruction to date of lead pollution over the Earth's southernmost continent.

Una nueva investigación revela que las granjas eólicas marinas son particularmente útiles para las focas, ya que parece que actúan como arrecifes artificiales, atrayendo a grandes grupos de peces.
El estudio realizado por investigadores de la Universidad de St. Andrews en Escocia fue publicado este mes en la revista Current Biology. Los cientÃficos de la investigación dieron seguimiento a un grupo de focas en el mar del Norte con el uso de dispositivos GPS. El propósito del estudio fue...

A los astrofÃsicos les encanta buscar razones por las cuales las teorÃas actuales son correctas. Cuando se obtienen los datos que no se ajustan a la teorÃa actual, se ha iniciado la carrera para llegar a una explicación!
El Universo es un lugar muy grande, lleno de incógnitas y los astrónomos que utilizan el Observatorio de Rayos X Chandra de la NASA, acaban de encontrar una nueva.

Outside the northern Guatemalan town of Olopa, near the Honduran border, farmer Edwin Fernando Diaz Viera stands in the middle of his tiny coffee field. He says it was his lifelong dream to own a farm here. The area is renowned for producing some of the world's richest Arabica, the smooth-tasting beans beloved by specialty coffee brewers.
"My farm was beautiful, it was big," he says.
But then, a plant fungus called coffee rust, or roya in Spanish, hit his crop.
"Coffee rust appeared and wiped out everything," he says.

Astro Physicists love to look for reasons current theories are correct. When data are obtained that do not fit a current theory, the race is on to come up with an explanation!
The Universe is a big place, full of unknowns. Astronomers using NASA's Chandra X-ray Observatory have just catalogued a new one.
"I couldn't believe my eyes," says Esra Bulbul of the Harvard Center for Astrophysics. "What we found, at first glance, could not be explained by known physics."

Istanbul, Turkey recently unveiled awesome new machines that help both the environment and needy animals. Each time a person recycles a plastic bottle in the designated receptacle, pet food is ejected into a bowl at the bottom so hungry stray animals have something to eat.
So far, the machines have been a hit with residents. People who would normally toss bottles in a trash can might wait to carry the plastic a bit longer to dispose of it in the recycling bin now that they know they can assist animals. It’s a win-win scenario that doubles Turkish people's incentive to do the right thing.
