Modified rice plant produces more grain, less methane

Apparently, the secret to better, more eco-friendly rice plant is another type of grain: barley. 

A team of scientists has created genetically modified rice that borrows a single gene from barley and found that the altered organism can generate up to 43 percent more grains per plant. Plus, its methane emission is down to 0.3 percent, a lot lower than regular rice's 10 percent emission observed during the scientists' experiments. Methane, as you might know, is one of the most potent greenhouse gases and is the second most prevalent in the US after carbon dioxide.

It's not 100 percent clear why the modified organism produces less greenhouse gas, but the scientists believe it could be because it stores more starch and sugar in its stems and grains than its roots. Regular rice has more starch and sugar in its roots, which tend to leak out and serve as food to microbes that turn them into methane. While this barley-rice organism sounds promising, the scientists still need to turn it into a variety farmers can easily cultivate, and that could take five to ten more years.

So this is basically / Asi que esto es basicamente... [SPANISH TEXT]

Si amigos, basicamente la idea del blog fue introducir a todos en el mundo de la tecnologia y hacer que esta no fuera tan "compleja" o "complicada" para todos. Ultimamente no hago reviews propios, ya que me tomo la molestia de elegir buenas noticias (que considero) para su placer informativo (bueno, las visitas me dicen que lo estoy haciendo bien) Pero, y si algun dia llegase a terminar todo? Regalar el dominio? Vender el blog? Nah, muchas veces me lo he preguntado pero... por algo senti el deseo de escribirles, desde mi misma mano y tecla, porque esto es lo que me apasiona: la tecnologia, la programacion, el llevar todo niveles superiores, exponenciar mi capacidad de analisis. De esto se trata todo, esto es basicamente el alma del blog: tecnologia. Actualmente me encuentro en otra ciudad, desde hace ya 1 mes. Las cosas han estado normales, pues dentro de lo que alguien podria definir de "normal". Gracias a Dios no me hace falta lo basico, desafortunad...

Child-friendly Galaxy Tab 3 Kids listed in Korean brochure

We're no experts in Korean back-to-school literature, but it looks as if one retailer has tipped Samsung's plans a little early. If the documents above are legitimate, then the company will launch a kiddie-focused Galaxy Tab in short order. The Galaxy Tab 3 Kids is said to be an 8.5-inch slate with a 1.2GHz dual-core CPU, a 1,024 x 600 WSVGA display, 8GB storage, 1GB RAM and Jelly Bean. The company has also seen fit to include 802.11 a/b/g/n WiFi, Bluetooth 3.0, a microSD card slot (no word on capacity) and a 4,000mAh battery. One thing that lends weight to the listing is that the device's model number is SM-T2105, which evleaks tersely described as a "Galaxy Tab for children" a month ago. There's more pictures over at the source, but not a single spec saying that this new device is resistant to jam-smeared fingers. Source: ENGADGET

The Ford Fiesta 2011 Was the Budget Hacker’s Dream (And No One Noticed)

The Ford Fiesta 2011 Was the Budget Hacker’s Dream (And No One Noticed) If you ever drove a Ford Fiesta 2011 SE and felt like it had hidden potential, you weren’t wrong — it was a software-defined vehicle before that was even a buzzword . While most saw it as a humble economy car, tinkerers and enthusiasts quickly discovered that the Fiesta was actually modular, reprogrammable, and surprisingly future-proof . With the right tools (and a bit of nerve), you could unlock features typically reserved for higher trims, all with minor hardware tweaks and some clever software work. Here’s a deep dive into the hidden arsenal of the 2011 Fiesta — and why it deserves a cult status among modders. The Secret Weapon: Shared Architecture Ford built the Fiesta using a highly modular electronic architecture . Many trims — from the base SE to the Titanium — shared the same PCM, wiring harnesses, and core modules . That meant you could: Add hardware from higher trims (like steering wheel...
