In new research published in the journal Nature Climate Change, an international scientific team has identified a powerful internal mechanism that could enable some corals and their symbiotic algae to counter the adverse impact of a more acidic ocean.
As humans release ever-larger amounts of carbon dioxide into the atmosphere, besides warming the planet, the gas is also turning the world's oceans more acidic -- at rates thought to far exceed those seen during past major extinctions of life. This has prompted strong scientific interest in finding out which species are most vulnerable, and which can handle the changed conditions.

lights
Specialists of the Center for Research and Advanced Studies (CINVESTAV) developed a lighting design very low power consumption and high efficiency.
The researcher Cyrus Falcony Guajardo explained that this technology may have an energy saving of up to 90% over conventional incandescent bulbs with the same lighting capacity.
An expert group of the Physics Department of CINVESTAV raised Zacatenco Unit strives to find materials that convert light to allow the LED'so light emitting diodes (currently emit a bluish light) in white light emitting through a better balance visible light color.
Falcony Guajardo said LEDs emit light with high efficiency, but in very narrow color spectrum (infrared, red, blue, violet and ultraviolet).
How are you explained that emissions do not allow proper ambient lighting to the human eye, the challenge was to synthesize materials that expand the spectrum of light from such devices.
The investigator noted that this is equivalent to the white appearance match that used in fluorescent lamps called "saving or cold light", which are placed inside the glass tube used in the lamp, which in the case of LED's is incorporated in the encapsulation thereof.
He explained that this technology has an impact on high efficiency and energy savings and in reducing environmentally harmful effects (such as those arising from the use of mercury in fluorescent lamps currently on the market).
Another benefit is seen with this project, which was supported by the Institute of Science and Technology of the Federal District, is the contribution to reducing global warming.
Falcony Cyrus stated that there are two patents pending and over 10 research publications in journals.
