Readers' Comments

What are your favorite new words from 2010?
Vuvuzela is a great word, one of the best to enter American popular culture in 2010, though it sounds nothing like an actual vuvuzela. A vuvuzela sounds like a long, droning moan, a sound full of garbage and tennis balls.
The vuvuzela’s long, plastic barrel provided Americans with the junk shot of sounds this year, the sort of noise you could hear even through a containment dome placed over a gushing underwater oil well owned by BP. (Though if you take a vuvuzela to the airport, you’re going to get an enhanced pat-down, sure as we could be entering adouble-dip recession.)
Close your eyes while someone blows a vuvuzela and you can see all this clearly, as if it were playing on a spill-camover your Web browser at work. Open them and it’s just a World Cup game highlight (speaking of great words: Uruguay vs. Ghana).
And the oil kept coming, all summer long, and with it new words — top killstatic kill, bottom kill — that meant failure, until at bottom they didn’t. (There may be put-backs for mortgage bonds. It doesn’t work so well with oil.)
Everyone was glad that the fish kill wasn’t as bad as it might have been. Dispersants may have worked. But the blowout preventer did not.
Refudiate is almost a better word than vuvuzela, because it’s not so much a real word as a neologism, one much of America attributes to Sarah Palin, the former governor of Alaska, who used it in a Twitter message in July. (She took a real shellacking for that.) The Oxford University Press called it the word of the year.
But refudiate was not Ms. Palin’s word first, even if she unpacked the portmanteau all by her lonesome. David Segal of The New York Times had it in print in late June, in an article about people who sell marijuana for a living. They are not easy to interview.
“Simple yes-or-no questions yield 10-minute soliloquies,” he wrote. “Words are coined on the spot, like ‘refudiate,’ and regular words are used in ways that make sense only in context.”
It’s like a halfalogue, talking to those guys.
Speaking of, did you see “Inception”? (Can Ms. Palin refudiate a claim that she took the word refudiate from a sleeping marijuana salesman?) Did you i-dose on Justin Bieber videos (I’m a Belieber!) or contemplate becoming one of the Hollywood star whackerswho sent Randy Quaid around a bend and up to Canada to seek asylum? Did you weep along with HungryBear’s double rainbow on YouTube, then seek double rainbows yourself?
Most important of all, did you stand for or against the ground zero mosque near the ground zero Century 21, some blocks away from ground zero itself but almost directly next door to a bar?
G.Z.M. was a big word for 2010, until it was not. On that subject, there wasquantitative easing as soon as the midterm elections were over.

The Words That Made the Year

The old and new puns, slang and jargon that we lived with this year. Compiled by Grant Barrett.
Pop Culture
belieber: A fan of Justin Bieberthe Canadian pop singer who also spawned ...
the Justin Bieber: A haircut also known as the flip and switch, the flow, or the twitch. Now driving parents crazy everywhere.
G.T.L.: For “gym, tan, laundry,” the life philosophy of the Situation, otherwise known as Mike Sorrentino of the reality TV program “Jersey Shore.” You laugh, but it’s worked for him.
i-dosing: A supposed digital drug. Certain soundwaves, the claim goes, give listeners a high. Skeptics abound, watchful parents are everywhere.
star whacker: The latest in celeb coinage. In October, the actor Randy Quaid and his wife, Evi, begged for asylum in Canada, claiming fear of star whackers, people who had already killed other famous people and were out to get them, too.
Communicating
coffice: In South Korea, a coffee shop habitually used as an office by customers, who mooch its space, electricity, Wi-Fi and other resources. Presumably, they pay for the coffee.
halfalogue: Half of a conversation, like an overheard phone call. The term was coined in the research paper “Overheard Cell-Phone Conversations: When Less Speech is More Distracting” in the journal Psychological Science.
sofalize: A British marketing term created for people who prefer to stay home and communicate with others electronically.
mansplainer: A man compelled to explain or give an opinion about everything — especially to a woman. He speaks, often condescendingly, even if he doesn’t know what he’s talking about or even if it’s none of his business. Old term: a boor.
social graph: The structure of personal networks, who people know and how they know them, especially online. The term probably came from the internal lingo at Facebook, but it has spread widely among technology companies.
Politics
demon sheep: The political ad that captured critics everywhere for being “baaad,” as The Wall Street Journal put it. The Senate campaign of Carly Fiorina used and retired the ad, but other campaigns quickly created their own parodies.
mama grizzly: Coined by Sarah Palin, “mama grizzly” is the conservative woman’s battle cry, referring to mothers who ferociously defend their children or policies that benefit them. Often used with humor. In her new book, Ms. Palin wrote that it’s “bear propaganda” to insist that these bears are cute and cuddly.
poutrage: False outrage, usually put on for personal, financial or political gain.
refudiate: Another Palinism, this time a blend of refute and repudiate. Now used with an eyebrow raised.
shellacking: President Obama’s preferred way to describe what happened to Democrats in the midterm elections. Some might call it a knock-down punch.
Travel
cuddle class: Economy-class airplane seats that unfold into a bed or couch, as proposed by Air New Zealand, which calls them “Skycouch” seats.
porno scanner: A full-body security scanner that provoked outrage at airports and on blogs. Also called strip-search scanners and, more politely, by the Transportation Security Administration, advanced imaging technology.
enhanced pat-down: Frisking in which security workers slide the palms of their handsdown a person’s body in a search for contraband or weapons.
Economy
double-dip recession: What economists talked about, and what every Obama administration official feared.
flash crash: The mystery of the financial markets this year: a May 6 market drop of almost 1,000 points.
peak water: Like “peak oil,” a theory that humans may have used the water easiest to obtain, and that scarcity may be on the rise.
QE2: Not the ocean liner, but the abbreviation for the Fed’s latest round of quantitative easing, its purchase of Treasury bonds. The term is usually used by critics derisively, and often in combination with another disaster, the sinking of the Titanic.
robo-signer and put-back: Even for people who never read their mortgage documents, these terms became inescapable as the foreclosure crisis hit. For the record, arobo-signer approves mortgage foreclosure notices without verifying its contents. A put-back is a mortgage sold back to an institutional seller because of problems with documentation.
The Oil Spill
containment dome: After the April 20 explosion on the Deepwater Horizon, everyone became an engineer. The containment dome? Yes, that seals the leak.
junk shot: Plugging the leak with old tires, golf balls and other debris.
static kill: Sealing the well by pumping in a synthetic mud from the top.
bottom kill: The same technique, only many thousands of feet further down the well through a relief well. How we got this education: the 24-hour spillcam that broadcast the leak.
Things
inception: Popularized by the movie “Inception,” the word expanded from its usual meaning and now refers to ideas planted in the dreams of other people.
double rainbow: A phrase from the hugely popular YouTube video by Paul Vasquez, featuring his breathless amazement at the sight of two rainbows at Yosemite National Park. It spawned parodies, television commercials, dance mixes, Auto-Tune versions, parties and Halloween costumes, and is now used to refer — ironically and not — to something amazing.
E.V.: An electric vehicle. While the term has been around for decades, there are now more cars like the Nissan Leaf and the Chevy Volt, which makes it more than an environmentalist’s pipeless dream.
G.Z.M.: An acronym for ground zero mosque — the shorthand term for a controversial Muslim community center proposed near the site where the World Trade Center was attacked.
vuvuzela: The South African plastic trumpet that invaded, like locusts, the World Cup matches in Johannesburg. Television viewers, as well as participants, couldn’t escape the buzzzzz.
Weird: Western, educated, industrialized, rich and democratic, an acronym and criticism of the typical subjects in studies by behavioral scientists. That is, they tend to be the easiest to recruit: undergraduates.

    La novedad tecnológica de este 2010 fue, sin duda, el iPad. Este dispositivo de la marca Apple reporta alrededor de 5 millones de unidades vendidas. Pese a ello, existen numerosas críticas en torno a su funcionamiento.
    Si bien la empresa dirigida por Steve Jobs ya trabaja en sus mejoras, conviene conocer las principales carencias de la actual versión. Las siguientes son las diez más incómodas, de acuerdo con el sitio electrónico Ondekoleji.com y un informe publicado por EL UNIVERSAL.
    1. Carece de Adobe Flash. Este programa es indispensable para ejecutar numerosas páginas de internet, especialmente aquellas que contienen animaciones y videos.
    2. Carece de un procesador multitareas. Esto impide la realización de dos o más tareas simultáneas. Quiere decir que no es posible abrir una página de internet mientras se chatea en Messenger.
    3. Carece de cámara web. Pese a ser un gadget ideado para llevar a cabo transmisiones en vivo y videoconferencias, le hace falta una cámara web. Esto es aun más notorio porque algunos dispositivos de la competencia sí cuentan con cámara.
    4. Carece de puertos USB. Esto lo hace incompatible con una infinidad de dispositivos y herramientas tecnológicas. Lo vuelve simplemente un circuito cerrado.
    5. Carece de títulos en español. La tienda de libros electrónicos iBooks no ofrece contenidos en español. De hecho, no se dicho nada respecto a la posibilidad de ofrecerlos, pues ni siquiera existen negociaciones con las editoriales de esta lengua.
    6. Sus aplicaciones están restringidas y son caras. A diferencia de otros dispositivos, el iPad no permite descargar aplicaciones de sitio que no estén autorizados por su fabricante, Apple. Además, sus aplicaciones permitidas tienen precios altos.
    7. Reproduce videos con una baja calidad. No reproduce video HD de 720p, ya que su resolución todavía es baja: 1024×768. Tampoco dispone de salida de video, ni de HDMI.
    8. Posee poca memoria RAM. Tiene 256 MB de RAM, lo que llega a convertirse en un problema al abrir varias ventanas en la red.
    9. Impide una lectura cómoda. Es muy complicado encontrar algún ángulo en que su pantalla deje de emitir reflejos que vuelvan incómoda la lectura.
    10. Carece de métodos de suscripción. De acuerdo con algunos desarrolladores, Apple aún no tiene un sistema de suscripción para los medios, por lo que se deben descargar ejemplar por ejemplar. Los usuarios deben llevar a cabo los propios sistemas de suscripciones o utilizar un servidor local.

'Father of the Internet in Japan' predicts the future of networked devices and tells us why Japan must deregulate online healthcare


By EJOVI NUWERE
Special to The Japan Times
In 1990, Jun Murai, at the time an associate professor at Keio University in Tokyo, made a prediction in an article in the Asahi Shimbun newspaper. When asked what the future of computer systems would look like, he described a world where, on one level there would be a network, on a second level computers and on a third, outer layer the human brain — all interconnected and communicating but being powered by the human mind. Murai's comments made such an impact that among the people who began to contact him he received an odd visit from one woman who said she now knew the source of the voice she heard in her head!

She had clearly been imagining things, but Murai — who was the first person in Japan to connect a computer to what we now know as the Internet (earning him the moniker "father of the Internet in Japan") — is likely to be the best person to talk to should such a situation arise.
At the Internet of Things 2010 Conference, held in Tokyo last week, Murai — who is now Dean, Faculty of Environment and Information Studies at Keio — sat down with The Japan Times to give his prediction for the next 20 years of the Internet.
"We are still not completely achieving what I predicted," he said, "brain connectivity is not here." But the conference — which focussed on networking and the interconnection of the everyday objects with which we live — may be bringing us closer. According to Murai it is the connection among all the activities within society that is important; A world where our television, our phone and pacemaker are all communicating with each other.
While the technology for device networking is already well in place, the usage of the information we can extract from these devices is still in the very early stages. "The information is there, even if you are not using it," said Murai. "One lit cigarette can be detected from space; the cigarette has no communication device in it but it can be detected by networked sensors." A large focus of the conference, and of Murai's research, is how can we utilize that kind of data. As he sees it, exploring new ways of harnessing this vast information network will be what drives the Internet in the next 10 to 20 years.
"We have many sensors around us gathering data, and a single computer cannot process it all," explained Murai. He believes we are leaving an Internet space represented by users "proactively generating, activating, and requesting the data" and moving into a more passive relationship with the network — one in which data will be "collected and processed from all things around us without our interaction."
To grasp the kind of world that Murai envisions, you have to look no further than the Nike+iPod sensors some runners use in their sneakers. These silently gather data on jogging patterns, which can be uploaded over wireless home networks to Nike's website without the user having to do anything. It is a world where data is gathered, processed and presented as you go about your normal life. "The way we compute the data will be the future of the Internet. And in this there are a infinite number of possibilities," Murai said.
Wireless communication and sensor technology have been around for some time but are rapidly increasing as more devices are able to communicate with each other. Some of the leading technology in this area has come from the transportation and automobile industry. "Did you know that KDDI mobile (au) was originally a division of Toyota before the mobile phone industry was even developed?" asks Murai.
The sensor technology within cars is some of the most advanced technology many people own. With the growth of electric vehicles, plugging your car into your home power source will also mean syncing it to your network, much as you sync your iPod. "You bring your car into the garage, connect it to your home network and it can be a control point, because the vehicle can be a storage device for electric power and also for data." Data that is gathered silently as we go about the course of day.
Today it is possible to browse Yahoo! maps on your TV and to produce a perfect driving route with your car-navigation system based on real-time traffic data in Tokyo. Soon, using the Internet of Things, your TV will download historical traffic data from your car and crunch that information with data gathered from 200 other cars in your city to generate the ideal traffic route and show you on your TV before syncing it to your car in the morning.
This kind of networked computation means solving complex problems faster than was ever possible before, and this will have all kinds of benefits. According to Murai, one area that will see a lot of change over the next 10 years due to the Internet of Things will be medical and health care.
At the moment we are able to improve health care through the analysis of DNA and molecular data. In the future we will have connected devices and the data they generate will help pinpoint the causes of disease. "There are always reasons why we have a sickness, but it's still mysterious why someone has cancer or has a specific disease." Using connected devices we can gather and compute all kinds of geographic, agricultural and environmental data. Which in turn may help us identify specific causes of disease. "We currently have an infinite number of possible causes, but in utilizing the data collected to find the similarities and the relationship between cause and result, that's going to be instantly effective in terms of medical care," Murai predicted.
"A serious issue in Japan is our aging society, with elderly people alone at home," Murai noted. "Even if they are living with family members, those family members have to go out to work, so the elderly remain alone at home — this is why the home networked environment is important." While this isn't specific to Japan, it will be one of the major issues facing the country in the next 10 to 20 years, he said.
Murai argues this will be driven by commercial investment as well as strategic deregulation. Companies will find advances in this area to be very profitable. People will pay a lot to stay in good health. Yet despite the obvious need for the embrace of such technology in Japan, there are still obstacles. Murai believes the most serious issue is government deregulation of health care and pharmaceuticals in relation to the Internet. "Any medical or professional care made remotely over the network is prohibited. That's a difficult problem for Japan," he said.
"Elderly people in the countryside can not order medicine online, so they have to go in person or get someone to help." But now we have the concept of the Internet of Things combined with fast fiber-optic connections to the home, why shouldn't a doctor be able to check up on a patient via a video-streaming channel broadcast to your home TV? Murai argues that with such abundant technology we have to look closely at issues such as caring for Japan's aging society. "We have to combine the Internet of Things and advanced technology with solutions for the future of society," he insists.

Los gérmenes intestinales pueden ser la causa de alergias y obesidad en países industrializados

Los gérmenes intestinales pueden ser la causa de alergias y obesidad en países industrializados

Un estudio compara las bacterias intestinales de niños europeos y africanos para explicar las diferencias en la prevalencia de algunas enfermedades.

Los gérmenes que habitan en los intestinos podrían ser los causantes de la mayoría de las alergias, problemas estomacales e, incluso, obesidad entre los niños que viven en los países ricos industrializados, según un estudio de la Universidad de Florencia y publicado en Proceedings of the National Academy of Sciences (PNAS).
El equipo comparó las bacterias intestinales de niños europeos con las de habitantes de Burkina Faso y halló suficientes diferencias como para explicar las disparidades en la enfermedad crónica y la obesidad. Los resultados sugieren que "la dieta tiene un papel dominante sobre otras posibles variables, como la etnia, salubridad, higiene, geografía y clima, a la hora de conformar la flora y fauna intestinales", señala Paolo Lionetti, uno de los investigadores.
El experto indica que se puede plantear la hipótesis de que "la reducción en riqueza que observamos en los chicos de Burkina Faso comparados con los de la Unión Europea, podría indicar cómo el consumo de azúcar, grasa animal y alimentos de altas calorías en los países industrializados está limitando rápidamente el potencial adaptativo de la flora y la fauna intestinales".
El estudio se ha basado en una serie de evidencias acerca de que la salud de los humanos depende fuertemente de los billones de microorganismos que habitan en nuestros cuerpos. Sólo una fracción de esos microorganismos causa directamente enfermedades, mientras que la gran mayoría ayuda a digerir los alimentos, afecta a otras bacterias e influiría en cientos de funciones biológicas.
Control de las enfermedades infecciosas, pero aumento de las alergias
"Los países desarrollados occidentales controlaron con éxito las enfermedades infecciosas durante la segunda mitad del siglo pasado, mejorando la sanidad y usando antibióticos y vacunas", ha afirmado el investigador. Sin embargo, "al mismo tiempo, se ha observado un aumento en nuevas enfermedades, como los desórdenes alérgicos y autoinmunes y la enfermedad inflamatoria intestinal, en adultos y niños", ha añadido.
Lionetti y su equipo estudiaron el ADN de las bacterias intestinales de niños de Burkina Faso, que reciben lactancia materna hasta los dos años y consumen una dieta rica en cereales, legumbres y vegetales, con poca carne. La dieta occidental, en cambio, se basa en un elevado consumo de carne, cereales procesados, azúcar y grasa.
De este modo, el equipo italiano halló que los niños africanos tenían muchas bacterias que los ayudaban a procesar la fibra, mientras que los europeos, no tantas. Las tasas son muy similares a las de otros estudios que compararon las bacterias intestinales de personas delgadas y obesas.
Además, los investigadores han afirmado que los hallazgos respaldarían "el desarrollo de productos probióticos para ayudar a restaurar el equilibrio ancestral y mantener a los seres humanos delgados y saludables".

El desequilibrio bacteriano intestinal está relacionado con la obesidad

El desequilibrio bacteriano intestinal está relacionado con la obesidad

Un inadecuado equilibrio de determinadas bacterias puede favorecer la acumulación de grasas y la inflamación del tejido adiposo.

Profesor Manuel Serrano Ríos.
Un inadecuado equilibrio bacteriano en el intestino puede favorecer la acumulación de grasas y la inflamación del tejido adiposo. Por el contrario, el adecuado equilibrio de ciertas bacterias (bifidobacterias) reduce la inflamación del tejido adiposo.
Así lo afirmó el profesor Manuel Serrano Ríos, Académico de la Real Academia Nacional de Medicina (RANM) y presidente del Instituto Danone, en la sesión que cerraba el ciclo de conferencias sobre nutrición organizadas por este Instituto en la RANM. El profesor afirmó que las bacterias del intestino tienen una función metabólica, muy conocida en el caso de los rumiantes -que no conseguirían transformar la fibra vegetal en proteína cárnica sin ellas- pero que también se ha demostrado que ayudan al organismo humano a ahorrar energía, permitiendo un mayor aprovechamiento de los nutrientes.
En la misma sesión, el Dr. Francisco Guarner, de la Unidad de Investigación de Aparato Digestivo del Hospital Vall d'Hebron de Barcelona y Miembro del Consejo Científico del Instituto Danone,
Diversos estudios han analizado la microbiota humana concluyendo que existe una relación entre obesidad y una diversidad bacteriana reducida en el organismo, por lo que abre una futura vía de control y seguimiento de pacientes obesos en el futuro. Los mecanismos mediante los que se actuaría sería mediante la administración de prebióticos y probióticos.
De hecho, la investigación sobre probióticos es una rama de la medicina que ha vivido un gran aumento de publicaciones en los últimos años y en la que se ponen grandes esperanzas no solo por sus propiedades beneficiosas ante ciertas patologías del aparato digestivo, sino también de las vías respiratorias, del sistema inmunitario, de infecciones vaginales, ciertas dermatitis, o del cáncer de colon.

Asocian el colesterol HDL con un menor riesgo de Alzheimer en mayores

Asocian el colesterol HDL con un menor riesgo de Alzheimer en mayores

Un estudio norteamericano con personas mayores de 64 años relaciona los niveles más elevados de HDL en plasma con un menor riesgo de desarrollar esta enfermedad.

Los niveles elevados de lipoproteínas de alta densidad (HDL), parecen estar asociados con un menor riesgo de Alzheimer en personas mayores, según un estudio de la Universidad de Columbia en Nueva York, Estados Unidos, que se publica en la revistaArchives of Neurology.
Los autores recuerdan que los niveles elevados de colesterol y triglicéridos, lo que se conoce como dislipidemia, y la enfermedad de Alzheimer de inicio avanzado son muy frecuentes en las sociedades occidentales.
Los investigadores, dirigidos por Christiane Reitz, estudiaron a 1.130 adultos para examinar la asociación entre los niveles de lípidos en la sangre y la enfermedad de Alzheimer. El estudio incluyó una muestra de residentes de Manhattan en Nueva York de 65 años o más sin antecedentes de demencia o deterioro cognitivo y se definieron los niveles más elevados de HDL como 55 mg por dl o más.
Los resultados mostraron que la edad media de los individuos cuando comenzaba la enfermedad era de 83 años. Los niveles más elevados de HDL en plasma se asociaron con un menor riesgo de presentar enfermedad de Alzheimer, incluso después de tener en cuenta factores de riesgo vasculares y tratamientos para reducir los lípidos.
Los autores concluyen que los mayores niveles de colesterol HDL se asociaron con un menor riesgo de enfermedad de Alzheimer e indican las características de la población de estudio, urbana y multiétnica con una alta prevalencia de factores de riesgo, por lo que los resultados no pueden generalizarse a individuos más jóvenes o con menos enfermedades.
