Fundación Antama presenta su guía de bolsillo: ‘Los cultivos MG en la Unión Europea’
Publicado por Alfredo L. Zamora en Noticias el 4 Dic, 2012 | 

 

Coincidiendo con el cumplimiento de los 15 años de siembra continuada de maíz modificado genéticamente en España, la Fundación Antama lanza su guía de bolsillo ‘Los cultivos modificados genéticamente en la Unión Europea’, un completo documento de referencia que pretende dar respuesta a las principales cuestiones que rodean la biotecnología agraria tanto a periodistas como a cualquier persona interesada en la materia.

La guía de bolsillo consta de 67 páginas en las que se ofrecen datos generales de la biotecnología agraria, su papel en la elaboración de alimentos y piensos, la normativa europea en torno a éstos, así como los retos mundiales ante los que esta tecnología juega un papel clave. La guía incluye también una sección en la que se da respuesta a las preguntas más frecuentes sobre estos cultivos y alimentos, tratando de solventar las controversias más comunes en torno a esta tecnología.

... y nosotros esperando que esta sociedad consumista intente derribar esa enorme barrera contra la alimentación-sana. Pues parece que no es posible, grandes multinacionales mantienen sus posturas en el gran ranking de los cultivos transgénicos, creyendo que es la única solución contra la excesiva demanda de productos alimenticios a nivel mundial, dejando de creer en bio-soluciones o al menos soluciones #sinresiduos. La carrera es larga y dura, no será fácil para nosotros, pero tan sólo nos bastará convencer a los más avispados, no somos tan ambiciosos, nos conformamos con muy poco. SL2 SONIA

Un video que explica un estudio publicado en Nature en el que se observa el efecto que causan los pesticidas en las abejas, las polinizadoras por excelencia en la naturaleza. La exposicón crónica a estos compuestos provoca cambios en las colmenas que lleva a un menor número de abejas en búsqueda de polen. Aunque los pesticidas provocan que el número de estas abejas aumente, también provoca que sean menos efectivas, por lo que limitan el crecimento de las colmenas y la polinización de otras flores.

 

Otros estudios han relacionado la desaparición de las abejas con la falta de alimentos en el futuro, debido a que se produciría una cantidad menor de vegetales, afectando a la cadena trófica desde la base.

DARPA shows off 1.8-gigapixel surveillance drone that can spot a terrorist from 20,000 feet above

DARPA shows off 1.8-gigapixel surveillance drone that can spot a terrorist from 20,000 feet above | Biosociedad | Scoop.it

DARPA and the US Army have taken the wraps off ARGUS-IS, a 1.8-gigapixel video surveillance platform that can resolve details as small as six inches from an altitude of 20,000 feet (6km). ARGUS is by far the highest-resolution surveillance platform in the world, and probably the highest-resolution camera in the world, period.

 

ARGUS, which would be attached to some kind of unmanned UAV (such as the Predator) and flown at an altitude of around 20,000 feet, can observe an area of 25 square kilometers (10sqmi) at any one time. If ARGUS was hovering over New York City, it could observe half of Manhattan. Two ARGUS-equipped drones, and the US could keep an eye on the entirety of Manhattan, 24/7.

 

It is the definition of “observe” in this case that will blow your mind, though. With an imaging unit that totals 1.8 billion pixels, ARGUS captures video (12 fps) that is detailed enough to pick out birds flying through the sky, or a lost toddler wandering around. These 1.8 gigapixels are provided via 368 smaller sensors, which DARPA/BAE says are just 5-megapixel smartphone camera sensors. These 368 sensors are focused on the ground via four image-stabilized telescopic lenses.

 

ARGUS’s insane resolution is only half of the story, though. It isn’t all that hard to strap a bunch of sensors together, after all. The hard bit, according to the Lawrence Livermore National Laboratory (LLNL), is the processing of all that image data. 1.8 billion pixels, at 12 fps, generates on the order of 600 gigabits per second. This equates to around 6 petabytes — or 6,000 terabytes — of video data per day. From what we can gather, some of the processing is done within ARGUS (or the drone that carries it), but most of the processing is done on the ground, in near-real-time, using a beefy supercomputer. We’re not entirely sure how such massive amounts of data are transmitted wirelessly, unless DARPA is waiting for its 100Gbps wireless tech to come to fruition.

 

The software, called Persistics after the concept of persistent ISR — intelligence, surveillance, and reconnaissance — is tasked with identifying objects on the ground, and then tracking them indefinitely. As you can see in the video, Persistics draws a colored box around humans, cars, and other objects of interest. These objects are then tracked by the software — and as you can imagine, tracking thousands of moving objects across a 10-square-mile zone is a fairly intensive task. The end user can view up to 65 tracking windows at one time.

Perfection Is Only Skin Deep: Everyone Has Many Flawed Genes (400 on average)

We all know that nobody's perfect. But now scientists have documented that fact on a genetic level. Researchers discovered that normal, healthy people are walking around with a surprisingly large number of mutations in their genes.

 

It's been well known that everyone has flaws in their DNA, though, for the most part, the defects are harmless. It's been less clear, however, just how many mistakes are lurking in someone's genes. "It's such an interesting question that people had been trying to make estimates from indirect approaches for a long time," says Chris Tyler-Smith of the Wellcome Trust Sanger Institute in Cambridge, England. "There were estimates that ranged from just a handful up to 100 or more serious disease-associated mutations."

 

But Tyler-Smith and his colleagues wanted to get a more precise, direct estimate. So they analyzed the DNA of 179 people from the United States, Japan, China and Nigeria who had volunteered to have their entire genetic blueprints deciphered through the 1,000 Genomes project. Now, in a paper appearing in the American Journal of Human Genetics, the researchers are reporting a big surprise.

"We found quite amazingly large numbers of deleterious and known disease-causing mutations," Tyler-Smith says. According to their analysis, the average person has around 400 defects in his or her genes, including at least a couple that are associated with disease.

 

The weird thing is, none of the people whose DNA was studied were severely sick. They all seemed perfectly happy and healthy. "It could be that in many cases the other copy of that gene or a similar gene within a multi-gene family takes over," Tyler-Smith says. "It's a bit surprising that people should be walking around apparently healthy yet we're seeing known disease-causing mutations in their genomes," he says. "But the answer was that these tended to be for mild and very often late-onset conditions. Things like heart disease, an increased risk of developing cancer."
