What do you know about the genius Sthephen Hawking? Very little is understood about Hawking in America or Canada,” says Anthony McCarten, the film’s screenwriter. “Nine of 10 people think he’s American. Most people think he was born disabled. They don’t know he was married and has three kids. There’s a lot of news to break with this film.”
The theory of everything is a movie based in the book of his ex wife travelling to infinitive: my life with Stephen.
In this story is showed not just when he falls in love, there is also something of his terriblee disease, and his most amazing accoplishments.
McCarrten, promises the movie is an excellent work, and says that when Hawking saw the completed film for the first time, he was crying.
If we want to learn more, we can begin to consider go to watch it!

Unrecognized marine microbes consume up to 90 percent of the methane in the deep sea that would otherwise escape.
Methane emissions from the oceans are largely controlled by a specific group of microorganisms, they can consume up to 90% of the methane that is generated in the deep-sea. When this methane is exploted, is generated the precipitation of authigenic carbonates.
Recently, a group of researchers have discovered a previously-unrecognized biological sink for a potent greenhouse gas: methane-breathing microbes living within rocky mounds on the seafloor. By using methane, these rock-dwelling microbes remove large amounts of the greenhouse gas from the ocean before they escape into the atmosphere. The findings were published in Nature Communications this week.
Methane-consuming microorganisms are known to live near cold seeps -- ocean floor areas where methane seepage naturally occurs -- as well as in thin layers of sediment on the surface of huge, rocky outcroppings of calcium carbonate surrounding seep sites. These tall structures are better known as foundations for coral and sponges and homes for rockfishes, clams, and crabs. Finding active methane-consuming microbes in the interior of carbonate rocks extends their known habitat and introduces a new ecological niche for key methane consumers.
"Methane is a much more powerful greenhouse gas than carbon dioxide, so tracing its flow through the environment is really a priority for climate models and for understanding the carbon cycle," Caltech’s Victoria Orphan says in a university statement. Her team previously found that two microorganisms that survive without oxygen work together to consume methane using sulfate from seawater: single-celled creatures called anaerobic methanotrophs and their bacteria partners. Until now, this two-microbe system has only been observed oxidizing methane at seeps.
“No one had really examined these rocks as living habitats before,” Andrew Thurber of Oregon State says in a news release. They were just assumed to be inactive, serving as passive recorders of methane oxidation over time. “This goes to show how the global methane process is still rather poorly understood.”
Using manned and robotic submersibles, the team collected rock samples from active cold seeps as well as carbonate mounds that appeared to be dormant at three sites: the tectonic plate boundary near Costa Rica (right), Eel River basin off the coast of northwestern California, and Hydrate Ridge off the Oregon coast (above). The rocks range in depth from 600 to 800 meters below the surface and in size from small pebbles to carbonate pavements stretching for dozens of kilometers.
Back at the surface, the carbonates were cracked, and a series of tests confirmed that the rocks did indeed host anaerobic methanotrophs and sulfate-reducing bacteria. Genetic analysis showed how they were related to methane-munchers previously characterized in seafloor sediment.
"The carbonate-based microbes breathed methane at roughly one-third the rate of those gathered from sediments near active seep sites," Caltech’s Jeffrey Marlow explains. The team used radiolabeled carbon-14 methane tracer gas to quantify the rates of methane consumption. "However, because there are likely many more microbes living in carbonate mounds than in sediments, their contributions to methane removal from the environment may be more significant."
|Carbonate rocks can rise more than a hundred meters above the seafloor at methane seep sites like this one at Hydrate Ridge, Oregon.|

Best wishes to Ms. Lilia Ernestina Montañez Hernández, who is leaving to Cuernavaca, Morelos, Mexico for her research stay at Instituto de Biotecnología de la UNAM. She will work there under the guidance of Dr. Ricardo Oropeza Navarro, who is her Co-Director of thesis. Hope her stay for about six moths at IBT will aid her to complete part of her Masters thesis. We are also positively hopeful that her stay will be purposeful, productive and beneficial to her both in terms of personal and professional aspects. Further, her stay will help other members of lab to learn from her and motivate them to aspire for national and International exhange programs to improve themselves. We are thankful to CONACyT for the beca mixta awarded to her and to Dr. Ricardo Oropeza for receiving and extending support to her and to our lab.

I am a fan of this TED-Ed videos, every time I watch one I have to suppress the urge to post it, but this one in particular made me think a lot. If the ocean is so big, how serious is the acidification?
My vision is pretty limited, but ever since I read about ocean acidification, I can't avoid skepticism.

Después de pasar las fiestas navideñas en compañía de los seres queridos y dejando atrás el año que termina, con cosas buenas y malas, nunca es tarde para un nuevo comienzo.
Nunca es tarde para cambiar la perspectiva de nuestra vida, cambiar nuestra mentalidad y así buscar un mejor desempeño en nuestras actividades, ya sean laborales, escolares, familiares, en cualquier ámbito; y así devolverle al mundo un poco de lo mucho que nos regala. Enfoquemonos en construir un buen futuro haciendo las cosas bien en el presente, pues como dijo alguna vez Jorge Luis Borges: "Modificar el pasado no es modificar un solo hecho, es anular sus consecuencias, que tienden a ser infinitas".
Como lo hace la naturaleza, hay que adaptarse a los cambios que surgen día con día en nuestro entorno, y la única manera de hacerlo es por medio de la evolución, aquella que desde hace miles de años permitió el perfeccionamiento de los seres vivos y que hoy en día nos mantiene en constante transformación.
Por eso iniciemos este año con una actitud positiva y no dejemos para mañana lo que podemos hacer hoy.
