Usted puede no darse cuenta de ello, pero en este preciso instante, está gastando innecesariamente electricidad en su casa. No se sienta tan mal, de hecho, la mayoría de la gente está utilizando más electricidad de la que necesita. La casa está llena de aparatos electrónicos, y darle seguimiento a todos ellos puede ser una verdadera molestia. La mayoría de nosotros tendemos a no pensar en ello. Después de todo, ¿qué daño posiblemente se puede hacer por dejar las luces encendidas en una habitación o colocando el termostato un par de grados más frío? Bueno, más de lo que probablemente piensa.

A study by the British Geological Survey and the Environment Agency reveals that almost all the the oil and gas bearing shales in England and Wales underlie drinking water aquifers, raising fears that widespread water contamination could occur. The British Geological Survey (BGS) in partnership with The Environment Agency (EA) have published a map which show the depth to each shale gas and oil source rock below principal groundwater aquifers in England and Wales.

Scientists have speculated for centuries about comets. Why do the become visible on an irregular interval? Why does the tail always point away from our sun? What are comets made of? Are they balls of ice, or more like an asteroid? Now NASA may finally get some concrete answers with a current mission that will land on a comet later this year! Comet 67P/Churyumov-Gerasimenko is releasing the Earthly equivalent of two glasses of water into space every second. The observations were made by the Microwave Instrument for Rosetta Orbiter (MIRO), aboard the European Space Agency's Rosetta spacecraft on June 6, 2014. The detection of water vapor has implications not only for cometary science, but also for mission planning, as the Rosetta team prepares the spacecraft to become the first ever to orbit a comet (planned for August), and the first to deploy a lander to its surface (planned for November 11).

Según un nuevo estudio, el 99% de los residuos de plástico que entra en el océano no puede ser localizado. Si bien inicialmente escuchar que hay menos plástico en el océano de lo que creíamos suena como una gran noticia, en realidad es una perspectiva aterradora. Después de todo, si el plástico no se encuentra en el océano...¡¿a dónde va?!

Forget marsupials, the world's strangest group of mammals are actually those in the Afrotheria order. This superorder of mammals contains a motley crew that at first glance seems to have nothing in common: from the biggest land animals on the planet—elephant—to tiny, rodent sized mammals such as tenrecs, hyraxes, golden moles, and sengis. But there's more: the group even includes marine mammals, such as dugongs and manatees. Finally, they also include as a member the most evolutionary-distinct mammal on the planet: the aardvark. While these species may seem entirely unrelated—and many were long shuffled into other groups—decades of genetic and morphological research now point to them all springing from the same tree. Last week, though, scientists announced the newest, and arguably cutest, member of Atrotheria: the Etendeka round-eared sengi. Described in the most recent edition of the Journal of Mammology, the Etendeka round-eared sengi (Macroscelides micus) was discovered in the northwest corner of Namibia.

According to a new study, 99% of plastic waste that enters the ocean cannot be located. While initially hearing that there's less plastic in the ocean than we believed sounds like great news, it's actually a frightening prospect. After all, if the plastic isn't in the ocean ... where is it going?! A team from the University of Western Australia spent a couple of years sailing around the world in five vessels hoping to accurately record just how much plastic is actually in the ocean. Although researchers expected to discover millions of tons, they were surprised to calculate that they only calculated about 40,000 tons of plastic floating on the surface.
