In a study published today in the journal Nature Climate Change, scientists from three universities demonstrate that buying a product made in China causes significantly higher carbon dioxide emissions than purchasing the same product made elsewhere. The study, titled "Targeted opportunities to address the climate–trade dilemma in China," is available here.

"The amazing increase in Chinese manufacturing over the past 15 years has driven the world economy to new heights and supplied consumers in developed countries with tremendous quantities of lower-cost goods," said co-author Steven J. Davis, UCI assistant professor of Earth system science. "But all of this has come at substantial cost to the environment."

When you think of the world’s greatest athletes, names like Usain Bolt generally spring to mind, but scientists have discovered the best athletes could well be found in the water, covered in scales.

It turns out that fish are far more effective at delivering oxygen throughout their body than almost any other animal, giving them the athletic edge over other species.

Los hoteles de todo el mundo están invitando cada vez más a los huéspedes a adoptar prácticas verdes. Sin embargo, mientras que los huéspedes piensan que están apoyando el medio ambiente apagando las luces y reusando toallas, pueden de hecho ser víctimas de "lavado verde", la práctica engañosa de una empresa que promueve programas de medio ambiente, mientras que obtiene beneficios extraordinarios.

Traffic noise is just another inconvenience for many of us. But for wildlife, noise from honking, and zooming vehicles can often be an insidious threat: it can degrade habitats without leaving any physical evidence of change, warns a recent study published in the Proceedings of the National Academy of Sciences.

Road noise — even in moderate levels — pushes migrating birds away from their stopover habitats, researchers from Boise State University in Idaho found. Those that stay back become weak.

“I was initially surprised that even moderate road noise — comparable to a suburban setting — would have such a wide-ranging impact on migrating birds,” William Laurance, a professor at James Cook University in Cairns, Australia, who was not involved in the study, told Mongabay. “On reflection, however, I guess such migrators have to be hyper-vigilent about noise, as they’re constantly moving to new areas where unseen predators could be lurking.”

¿Se imagina usted un medicamento que hiciera más fácil aprender un idioma, agudizar su memoria y ayudar a las personas con demencia y enfermedad de Alzheimer reprogramando el cerebro manteniendo las neuronas vivas?

Las personas con una demencia como la enfermedad de Alzheimer pierden la memoria cuando las células del cerebro se encogen y mueren porque las conexiones ya no pueden transferir la información.
