El aire acondicionado se ha vuelto indispensable para muchas organizaciones, es vital para tener una temperatura ideal y así permitir que la gente tenga condiciones óptimas para trabajar y desarrollar de mejor manera su labor.

También se ha convertido en un elemento indispensable en la factura eléctrica, aunque lo veamos tan solo como un pequeños dispositivo para bajar un par de grados centígrados la temperatura,  no es tan sencillo, porque utiliza motores grandes los cuales consumen mucha energía para bajar ese “par de grados centígrados”; la gente de servicios generales sabe perfectamente el impacto económico que esto representa a la empresa, así que ¿por qué no echarle una mirada a las opciones para disminuir el consumo de electricidad?

The state of California is asking a basic question right now that people often fight over: What's a fair way to divide up something that's scarce and valuable? That "something," in this case, is water.

There's a lot at stake, including your very own nuts, fruit and vegetables, because most of the water that's up for grabs in California goes to farmers. This year, some farmers will get water, and others will not, simply based on when their land was first irrigated.

Consider, for instance, the case of Cannon Michael. He grows tomatoes and melons in California's Central Valley. And despite the drought, he'll still grow them this year.

University of Wisconsin-Madison researchers have announced a significant step forward in the development of materials that can ward off oil — a discovery that could lead to new protective coatings and better approaches to cleaning up oil spills. In a new paper in the journal Advanced Functional Materials, professor of chemical and biological engineering David Lynn and assistant scientist Uttam Manna describe new coatings that are extremely oil-repellant (or "superoleophobic") in underwater environments.

Every child's ability to succeed in school is influenced by lots of external factors: teacher quality, parenting, poverty, geography, to name a few. But far less attention has been paid to the power of a child's bedroom walls. Or, rather, the paint that's on them and the lead that may be in that paint. A new study published in the Harvard Educational Review suggests that efforts to reduce kids' lead exposure have led to tangible academic gains in Massachusetts.

Japan's latest plans for 'scientific whaling' in the Southern Ocean have fallen at the first hurdle, writes Tony Press. The IWC's expert panel says Japan's proposal contains 'insufficient information' on which to judge its validity, in particular the need for the 'lethal sampling' of over 3,996 Minke whales that is central to the research plan.
