El nopal, el mejor purificador de agua en el mundo

La perfección tecnorgánica del cactus conocido como nopal (Opuntia ficus-indica) ha demostrado ser un filtro altamente eficiente para limpiar el agua y purificar sus toxinas. Es además un recurso accesible, natural y muy efectivo.

Al menos desde principios del siglo XIX, si no es que desde muchos años antes, las comunidades indígenas en México han utilizado al cactus conocido como nopal(Opuntia ficus-indica) para purificar el agua que beben. Resulta que ahora, 200 años después, estudios científicos han demostrado que la baba o goma de esta cactácea podría ser el más natural y eficiente purificador de toxinas en el agua.

Frente a la necesidad de hallar métodos prácticos de purificación de agua, considerando que la mayoría de los mecanismos empleados por las sociedades “desarrolladas” son insuficientes por la complejidad de su uso y mantenimiento, investigadores de la Universidad del Sur de Florida en Tampa, realizaron pruebas con muestras de agua combinada con grandes cantidades de sedimento y altos niveles de bacterias Bacillus cereus. El resultado fue que al ser filtrada a través de la baba o goma del nopal, las partículas del sedimento se unieron precipitándose al fondo del recipiente y las bacterias se combinaron y fijaron, eliminando más de un 98% de ellas.

[2020-02-13] Voting App Flaws Could Have Let Hackers Manipulate Results | WIRED

New research from MIT shows that the Voatz app appears to have some glaring security holes.

West Virginia and Oregon have both recently deployed a mobile voting app called Voatz to facilitate absentee voting. But Voatz now turns out to have major security flaws, according to researchers from the Massachusetts Institute of Technology—including vulnerabilities that could let a hacker manipulate results.

The newly unearthed bugs could allow an attacker to reveal someone’s votes, block votes from being submitted, or even manipulate them. The findings, first reported in The New York Times, come as the United States is grappling with broad election security issues and debating whether mobile voting can safely expand accessibility. Security experts have long warned that it’s virtually impossible to guarantee safe mobile voting, while Voatz and other companies argue that technologies like biometric authentication and blockchain will make the process secure. Apparently note quite yet, though.

“Given the severity of failings discussed in this paper, the lack of transparency, the risks to voter privacy, and the trivial nature of the attacks, we suggest that any near-future plans to use this app for high-stakes elections be abandoned,” wrote MIT researchers Michael Specter, James Koppel, and Daniel Weitzner.

Voatz is changing how people vote. Available by invitation on iPhone and Android.

Voatz is on a mission to make voting safer and more accessible. All citizens have a right to vote regardless of their circumstance.

[2020-01-22] AI in the court: Are robot judges next? | ZDNet

As in many other industries, AI carries great promise as well as risks for the legal industry. In the court system, though, the stakes are unusually high. Using a predictive algorithm to determine your child custody terms isn’t quite the same as Netflix suggesting which movie you should watch next.

Even so, AI and automation are already playing a large part in the US legal system. At a conference in Portland, Oregon last week, hosted by the Legal Services Corporation, legal professionals from around the country gathered to collectively pause and consider how they’re modernizing their systems — and to what extent they should be using AI.
