Éxitos de ayer: Alive - P.O.D. + VIDEO

“Alive” es el título de la canción del grupo estadounidense de metal cristiano P.O.D.. Fue lanzado el 7 de julio de 2011 como el primer sencillo de su éxitoso álbum Satellite. En 2002, la canción fue nominada al Premio Grammy a la mejor interpretación de hard rock y su video musical fue nominado en varias categorías en los MTV Video Music Awards de 2002. Con esta canción la banda comenzó a darse a conocer mundialmente como una de las mejores bandas de rock cristiano. La letra habla sobre como la gente vive la vida como la quiere vivir pero sin abrir los ojos y detenerse para agradecer por seguir vivos. 


La canción ingresó en las listas justo antes de los atentados del 11 de septiembre de 2001 y adquirieron un significado especial para el público estadounidense gracias a su mensaje positivo.2 El guitarrista Marcos Curiel expresó en una entrevista concedida en 2008, la importancia de la canción: "Hay demasiadas cosas negativas que suceden en nuestra vida cotidiana. Cuando escuchen algo que le puede dar una sensación de optimismo como "Alive" o "Youth of the Nation" nos sentimos realizados con nuestro trabajo como artista. Tratamos de ser relevante para la gente."


Por su parte, el cantante Sonny Sandoval afirmó: "En un principio, no teníamos un nombre para esta canción. En un tiempo pensamos titularlo como "Beautiful" (Bello), porque es lo que nos hizo sentir al componerla. Porque queríamos que la gente al escucharla dijera: "Hey! me hace sentir bien". "No sé cuántas veces hemos grabado el coro, porque fue como decir "Tenemos que ir a un nivel superior, hay que dar lo mejor".

Video Musical




Fue dirigido por Francis Lawrence, con efectos especiales de Pixel Envy. Fue estrenado el 20 de agosto de 2001 por las cadenas televisivas de música.5 En él, muestra una colisión de un automóvil con un autobús en un cruce de carreteras en el Valle de San Fernando rodado a mediados de 2001. Lawrence tuvo esta idea hace años, pero no logró que lo difundan entre otros grupos. Durante la filmación del video, Lawrence dijo: "Me alegro de no haber compartido la idea con otros grupos, porque con éste fue perfecto". El desarrollo del video durante el rodaje se centra en un día libre en la vida de un adolescente.


Lawrence también ha cambiado algunas escenas de su concepto original: el niño sale ileso de su automóvil destruido en cambio no aparece en absoluto, y abraza a su novia en un túnel del tren en lugar de una escena de sexo en una habitación como Lawrence había previsto anteriormente. Todos los efectos especiales y el trabajo detrás de "Alive" se detallan en un artículo retrospectivo en MTV en agosto de 2002.



A pesar de que no ha ganado ningun premio, "Alive" fue uno de los más nominados en la ceremonia de los MTV Video Music Awards de 2002. Sin embargo, ganó otros dos premios, además de las cinco nominaciones "VMA".



La letra de la canción:


Everyday is a new day

I'm thankful for every breath I take
I won't take it for granted
So I learn from my mistakes

It's beyond my control

Sometimes it's best to let go
Whatever happens in this lifetime
So I trust in love
You have given me peace of mind

I, I feel so alive

For the very first time
I can't deny you
I feel so alive
I, I feel so alive
For the very first time
An' I think I can fly

Sunshine upon my face

A new song for me to sing
Tell the world how I feel inside
Even though it might cost me everything

Now that I know this

So beyond, I can't hold this
I can never turn my back away
Now that I see you
I can never look away

I, I feel so alive

For the very first time
I can't deny you
I feel so alive
I, I feel so alive
For the very first time
An' I think I can fly

An' now that I know you

I could never turn my back away
An' now that I see you
I could never look away
An' now that I know you
I could never turn my back away
An' now that I see you
I believe no matter what they say

I, I feel so alive

For the very first time
I can't deny you
I feel so alive
I, I feel so alive
For the very first time
An' I think I can fly

I, I feel so alive

For the very first time
An' I think I can fly

I, I feel so alive

For the very first time
An' I think I can fly

An' I think I can fly

An' I think I can fly
An' I think I can fly

¿En qué país se dedica más tiempo a la vida social?


¿En qué país se dedica más tiempo a la vida social?
De todos los habitantes del planeta, los turcos son los que más tiempo pasan socializando con otras personas dentro de sus propias casas o visitando a amigos y familiares en sus domicilios (8,3 horas semanales). Les siguen los noruegos (6,5 horas) y los norteamericanos (6,1 horas). Y los que menos vida social tienen dentro de los hogares son los habitantes de Australia (0,4 horas), según un reciente estudio de la Universidad de Oxford que publicaba la revistaSocial Indicators Research.


Por otra parte, quienes más tiempo dedican asocializar fuera de casa son los holandeses (8,2 horas cada semana). En segunda posición se sitúan los habitantes de Noruega (56 horas), mientras que el tercer puesto es para los españoles (5,1 horas).



Los franceses ostentan otro récord por las horas que pasan sentados a la mesa de un restaurante o un café (3,2 horas semanales), seguidos de los brasileños (2,6 horas) y los canadienses (2,3 horas). Los ciudadanos del este de Europa son los que menos tiempo dedican a comer fuera de casa (0,2 horas).

Tú también puedes tener alucinaciones auditivas


Cuando nos cuentan que alguien dice “oir voces” de personas que realmente no están presentes, nos viene a la cabeza el término ‘alucinación’. Las alucinaciones son un fenómeno que estamos acostumbrados a asociar a trastornos mentales como la esquizofrenia. Sin embargo, todos podemos sufrirlas alguna vez…

Las alucinaciones auditivas verbales se definen como aquellas percepciones subjetivas en forma de conversaciones externas que suceden en ausencia de estímulos externos. Aunque a muchos nos resulten un tema interesante, aquel que las padece las vive como algo no deseado, que se presenta de forma intrusiva e inintencionada y que genera malestar. Este tipo de fenónemos puede variar desde sólo un sonido hasta una conversación, y en general suena como voces normales con su volumen, tono y acento particulares que de forma más frecuente se perciben como procedentes del entorno (y no del interior del individuo).

Aunque este tipo de alucinaciones suele ser un síntoma de enfermedades como la esquizofrenia, el parkinson o incluso el alzhéimer, existen estudios que estiman que hasta un 13.2% de la población sana las padece. Pueden presentarse justo cuando nos vamos a quedar dormidos o al despertarnos, y tanto el estrés como el cansancio son factores precipitantes muy comunes, tanto en el contexto de una enfermedad mental como sin ella.


Dos de las hipótesis neurocognitivas más recientes se describen en un artículo de la revista Brain Sciences en 2013. Una de esas hipótesis plantea que las alucinaciones verbales suceden a consecuencia de un fallo en el auto-monitoreo verbal que no proporcionaría información adecuada a las cortezas somatosensoriales. Esto haría que la experiencia subjetiva de hablar con uno mismo aparecería como inintencionada y se interpretase como si fuesen otros los autores de la conversación. La segunda de esas hipótesis sugiere un modelo aberrante de memoria según el cual losprocesos de memoria deficientes estarían en la base de las alucinaciones verbales. Según este planteamiento, los fallos en inhibición de recuerdos traumáticos podrían generar pensamientos intrusivos que se interpretasen como procedentes de otras personas.

También recientemente, con los descubrimientos realizados utilizando técnicas de neuroimagen y conectividad neural, se ha descrito que en las alucinaciones auditivas verbales podría darse un patrón de conexión alterado en la red fronto-temporal, involucrada en el procesamiento del lenguaje y la memoria. Además, estos hallazgos se han encontrado tanto en pacientes psicóticos como en personas sanas que sufrían alucinaciones auditivas de tipo verbal.

10 rules of photo composition (and why they work)

In photography, it’s not just what you shoot that counts – the way that you shoot it is crucial, too. Poor photo composition can make a fantastic subject dull, but a well-set scene can create a wonderful image from the most ordinary of situations. With that in mind, we’ve picked our top 10 photo composition ‘rules’ to show you how to transform your images, as well as offered some of our best photography tips from the experts who do it on a daily basis.
10 rules of photo composition (and why they work)
Don’t feel that you’ve got to remember every one of these laws and apply them to each photo you take. Instead, spend a little time practising each one in turn and they’ll become second nature. You’ll soon learn to spot situations where the different rules can be applied to best effect.
Photo composition doesn’t have to be complicated. There are all sorts of theories about the ‘Rule of Thirds’ and more complex ‘Golden Mean’, for example. But if you pay too much attention to strict formulae, your photos will lose any kind of spontaneity.
In the real world, you’ll be working with a wide range of subjects and scenes, and this requires a more open-minded approach. What works for one photo won’t necessarily work for another.
The key thing is to understand how all the decisions you make about composition can affect the way a shot looks and how people perceive your photos. The way you frame a shot, choose a focal length or position a person can make all the difference (check out our Photography Cheat Sheet series for quick fixes to some of these problems).
Technical know-how is very important in photography, of course, and even in some aspects of photo composition. But to take great shots you need visual knowledge too. Here are 10 key things to look out for…

10 rules of photo composition (and why they work)


Photo Composition Tip 1: Simplify the scene
10 rules of photo composition (and why they work)
Image copyright Jure Kravanja
When you look at a scene with your naked eye, your brain quickly picks out subjects of interest. But the camera doesn’t discriminate – it captures everything in front of it, which can lead to a cluttered, messy picture with no clear focal point.
What you need to do is choose your subject, then select a focal length or camera viewpoint that makes it the centre of attention in the frame. You can’t always keep other objects out of the picture, so try to keep them in the background or make them part of the story.
Silhouettes, textures and patterns are all devices that work quite well in simple compositions.
Why it works…
10 rules of photo composition (and why they work)

Photo Composition Tip 2: Fill the frame
10 rules of photo composition (and why they work)
Image copyright Jure Kravanja
When you’re shooting a large-scale scene it can be hard to know how big your subject should be in the frame, and how much you should zoom in by. In fact, leaving too much empty space in a scene is the most widespread compositional mistake (learn how to Replace boring skies in Photoshop). It makes your subject smaller than it needs to be and can also leave viewers confused about what they’re supposed to be looking at.
To avoid these problems you should zoom in to fill the frame, or get closer to the subject in question. The first approach flattens the perspective of the shot and makes it easier to control or exclude what’s shown in the background, but physically moving closer can give you a more interesting take on things (see our list of Digital camera effects from A-Z).
Why it works…
10 rules of photo composition (and why they work)

Photo Composition Tip 3: Aspect ratio
10 rules of photo composition (and why they work)

It’s easy to get stuck in a rut and take every picture with the camera held horizontally. Try turning it to get a vertical shot instead, adjusting your position or the zoom setting as you experiment with the new style. You can often improve on both horizontal and vertical shots by cropping the photo later.
After all, it would be too much of a coincidence if all your real-life subjects happened to fit the proportions of your camera sensor. Try cropping to a 16:9 ratio for a widescreen effect, or to the square shape used by medium-format cameras.
Why it works…
10 rules of photo composition (and why they work)

Photo Composition Tip 4: Avoid the middle
10 rules of photo composition (and why they work)
Image copyright Piriya Pete Wongkongkathep
When you’re just starting out, it’s tempting to put whatever you’re shooting right in the centre of the frame. However, this produces rather static, boring pictures. One of the ways to counteract this is to use the Rule of Thirds, where you split the image up into thirds, both horizontally and vertically, and try to place your subject on one of these imaginary lines or intersections. This is an overrated approach, though.
Instead, move your subject away from the centre and get a feel for how it can be balanced with everything else in the scene, including any areas of contrasting colour or light. There are no hard and fast rules about achieving this kind of visual balance, but you’ll quickly learn to rely on your instincts – trust that you’ll know when something just looks right.
Why it works…

Photo Composition Tip 5: Leading lines

A poorly composed photograph will leave your viewers unsure about where to look, and their attention might drift aimlessly around the scene without finding a clear focal point. However, you can use lines to control the way people’s eyes move around the picture.
Converging lines give a strong sense of perspective and three-dimensional depth, drawing you into an image. Curved lines can lead you on a journey around the frame, leading you towards the main subject.
Lines exist everywhere, in the form of walls, fences, roads, buildings and telephone wires. They can also be implied, perhaps by the direction in which an off-centre subject is looking.
Why it works…
10 rules of photo composition (and why they work)

Photo Composition Tip 6: Use diagonals
10 rules of photo composition (and why they work)
Image copyright Jure Kravanja
Horizontal lines lend a static, calm feel to a picture, while vertical ones often suggest permanence and stability. To introduce a feeling of drama, movement or uncertainty, look for diagonal lines instead.
You can need nothing more than a shift in position or focal length to get them – wider angles of view tend to introduce diagonal lines because of the increased perspective; with wide-angle lenses you’re more likely to tilt the camera up or down to get more of a scene in.
You can also introduce diagonal lines artificially, using the ‘Dutch Tilt’ technique. You simply tilt the camera as you take the shot. This can be very effective, though it doesn’t suit every shot and is best used sparingly (see our 44 essential digital camera tips and tricks).
Why it works…
10 rules of photo composition (and why they work)

Photo Composition Tip 7: Space to move
10 rules of photo composition (and why they work)
Image copyright Max Earey
Even though photographs themselves are static, they can still convey a strong sense of movement. When we look at pictures, we see what’s happening and tend to look ahead – this creates a feeling of imbalance or unease if your subject has nowhere to move except out of the frame.
You don’t just get this effect with moving subjects, either. For example, when you look at a portrait you tend to follow someone’s gaze, and they need an area to look into (check out ourFree portrait photography cropping guide).
For both types of shot, then, there should always be a little more space ahead of the subject than behind it.
Why it works…
10 rules of photo composition (and why they work)

Photo Composition Tip 8: Backgrounds
10 rules of photo composition (and why they work)
Image copyright John Powell
Don’t just concentrate on your subject – look at what’s happening in the background, too. This ties in with simplifying the scene and filling the frame. You can’t usually exclude the background completely, of course, but you can control it.
You’ll often find that changing your position is enough to replace a cluttered background with one that complements your subject nicely (find out how to Fix background distractions in 3 steps). Or you can use a wide lens aperture and a longer focal length to throw the background out of focus.
It all depends on whether the background is part of the story you’re trying to tell with the photo. In the shot above, the background is something that needs to be suppressed.
Why it works…
10 rules of photo composition (and why they work)


Photo Composition Tip 9: Creative with colours
10 rules of photo composition (and why they work)
Image copyright Jure Kravanja
Bright primary colours really attract the eye, especially when they’re contrasted with a complementary hue. But there are other ways of creating colour contrasts – by including a bright splash of colour against a monochromatic background, for example. You don’t need strong colour contrasts to create striking pictures, though (find out How to conquer high contrast with auto-exposure bracketing).
Scenes consisting almost entirely of a single hue can be very effective. And those with a limited palette of harmonious shades, such as softly lit landscapes, often make great pictures.
The key is to be really selective about how you isolate and frame your subjects to exclude unwanted colours.
Why it works…
10 rules of photo composition (and why they work)

Photo Composition Tip 10: Breaking the rules
10 rules of photo composition (and why they work)
Image copyright John Powell
Photo composition is a little like a visual language – you can use it to make your pictures pass on a specific message. However, just as we sometimes use the written word to create a deliberately jarring effect, we can do the same with photos by breaking with standard composition conventions.
Doing it by accident doesn’t count, though! It’s when you understand the rules of composition and then break them on purpose that things start to get interesting. It’s often best to break one rule at time, as John Powell does in the image above.
Just remember: for every rule we suggest, somewhere out there is a great picture that proves you can disregard it and still produce a fantastic image!

Columpio en el fin del mundo


Colgando sobre el borde de un acantilado en Ecuador
Lo llaman el Columpio del fin del mundo, una atracción extrema en las montañas de Ecuador que le otorga a los aventureros la oportunidad de balancearse sobre un abismo sin ninguna medida de seguridad.
Caminando por la carretera en la zona de Bellavista de Baños, Ecuador, las personas pueden llegar a un mirador y una estación de vigilancia sísmica llamada La Casa del Árbol (Tree House). Como su nombre lo indica, es una pequeña casa construida en un árbol en el borde de un cañón.
La vista desde allí por sí sola vale la pena el esfuerzo de caminar, pero para los adictos a la adrenalina, La Casa del Árbol ofrece un aspecto único: un columpio que cuelga sobre el precipicio. Lo creas o no, muchas personas que van al sitio realmente utilizan el columpio solo para ver como es balancearse sobre el vacío, e Internet está lleno de fotos de miedo de esta gente colgando sobre el abismo.
Supuestamente es una buena manera de mantenerse entretenido cuando las nubes bloquean la vista del volcán Tungurahua en Ecuador, pero simplemente no se puede dejar de pensar en la posibilidad de que se rompan las cuerdas y esta atracción termine con un desenlace fatal. ¿tendrás el coraje?

4 Things To Consider When Buying Your First Interview Suit


interview

Going out on your first job interview can be stressful. The clothing you wear to the interview shouldn't be.
For guys, there's just one appropriate thing to wear: A suit.
There's a difference between buying a first suit for interviews and a whole wardrobe of suits once the job has started.
Think of a first suit as a springboard, giving the wearer the necessary look to shine in an interview, without making an impression on its own.  
The last thing an interview suit should do is stand out.
Here are a few things to consider when you're shopping for the perfect interview suit:
Colors and Patterns
Blue or medium to dark grey, two buttons, no pinstripes. Black is too formal for interviews, and earth tones are too casual. Two button suits are the professional standard. Though you will see three button and one button suits, they should only be considered when your wardrobe requires multiple suits.  
The same goes for patterns like pinstripes. Once you're wearing a suit regularly, they're fine, for the first suit, basic is best.
Price
A solid price point for the first suit should be around $500, give or take a little. There are plenty of options around and below that amount, but avoid very inexpensive suits, as they are often poor quality and will look cheap.  
You want a suit that will last you through multiple rounds of interviews, not one that will come apart at the seams after a few marathon interview days.  
On the other side of the spectrum, you don't want to spend thousands on this suit. What will an interviewer think if you show up at an interview for an entry level position in a suit that's more expensive than theirs? It's not a risk worth taking, as it may have a negative impact on your candidacy.
Fit
  • Jacket: The best method for determining fit for an off-the-rack suit is to start with the jacket. 
    Bring a dress shirt with you when you go to the store so you can recreate how it'll be worn. The jacket won't fit the same way with a T-shirt underneath as it will with a dress shirt.  
    Put on the jacket and button the first button. Take your fist and put it between your torso and the jacket at the point where it buttons. Can you fit it there comfortably? If so, size down until you can't, at which point you know what's too small.  
    Buy the size larger than the one where your fist no longer fits. The point of this exercise is to make sure the suit looks normal when buttoned. If it is too tight in the torso, it'll pinch, making you look like Chris Farley
  • Pants: It's better to buy larger rather than smaller, since it's much easier to have pants taken in than it is to have them let out. If a pair feels a little tight, size up. Most suit pants come unfinished, meaning you'll need to take them to a tailor anyway to have them hemmed to your desired length. 
    If they are not unfinished, go with what feels right. The general rule is to have a little bit of break (how much of the pant leg sits on top of your shoe). More fabric than that, and the pants will look too baggy around the ankles, which will make you look shorter. A perfectly fitting jacket can be undone by baggy pants, and vice versa.
Accessories
Leave them at home, unless it's interesting socks.
The important thing to consider with interview suits is that they are meant to make you look polished, professional ,and no more, so that you can get down to business and impress the interviewer with your skills and attitude.  
The suit has done its job perfectly if the interviewer can't remember it, since you want them to remember you rather than what you wore. This keeps them focused on your abilities, with the added benefit being that you'll be able to wear the suit again with a different shirt/tie combination when they ask you back for round two.

Una aeronave militar rusa aterriza en una playa de turistas




(CNN) - Disfrutas de un día fantástico en la playa y, casi sin aviso, observas un gigantesco vehículo militar aproximarse hasta la orilla.
Lo que parece propio de una película sucedió en Rusia.
Los bañistas en Mechnikovo, cerca de Kaliningrado, se llevaron una gran sorpresa cuando un aerodeslizador militar de 500 toneladas aterrizó en la orilla de la playa, muy cerca de ellos.
Según el Ministerio de Defensa ruso, se trató de una práctica normal dentro de un ejercicio de entrenamiento rutinario, al tiempo que indicó que la playa está en terreno militar.

Here's Why Mosquitoes Can't Transmit HIV

HIV/AIDS kills about 1.6 million people every year, according to the most recent World Health Organization data. Hopefully, high school health classes taught us all how to avoid contraction: Don't have random, unprotected sex or use dirty needles.
mosquito on skin Mosquitoes function the same way as hypodermic needles though — They can both inject chemicals and extract blood. And if mosquitoes carry West Nile Virus and other blood-borne diseases, shouldn't they logically be able to transmit HIV, too?
Thankfully, we were reassured that that's not the case. Mosquitoes can not transmit HIV.
"It's definitely not a stupid question," Joe Conlon, former Navy entomologist and current technical advisor for the American Mosquito Control Association, told Business Insider.
Conlon explained that first of all, when a mosquito bites you, it draws your blood into its gut. Acids there kill the HIV virus. Plain and simple.
Even if the mosquito's stomach acids didn't render the virus harmless, it wouldn't be able to get back out of the insect. 
That's because mosquitoes use two different tubes to suck up blood and to inject you with saliva that stops your blood from clotting up while it's drinking. Even if a mosquito had virus-containing blood from another human inside it, the blood would never exit the bug through its salivary glands and into your blood stream.
"For a mosquito to transmit a disease, it's gotta pick up the virus. The virus has to survive in the gut and then get outside the gut into the body cavity and then eventually into the salivary glands to be injected into something else. It's a very complicated process, and with HIV, it just doesn't happen," Conlon said.
Malaria parasites, on the other hand, are able to grow in the mosquito gut, then migrate specifically to the salivary glands to continue their lifecycle in another human.
Thank goodness HIV doesn't have that ability. If mosquitoes spread HIV the way they spread Malaria, we'd have a million more deaths every year on our hands.



5 alimentos que jamás deberías comer

(CNN Español) – El doctor Sanjay Gupta, corresponsal médico de CNN, presentó en su segmento "Food for life" cinco alimentos que jamás deberíamos comer, según el editor de la revista Men's Health David Jack.
1. Fresas no orgánicas: Un equipo de expertos que investiga la forma en que se cultivan las frutas y verduras ha detectado la presencia de más de 13 pesticidas en las fresas que consumimos habitualmente, según Jack. La recomendación es optar por el producto orgánico.
2. Chocolate blanco: El cacao puro contiene antioxidantes beneficiosos para nuestra salud, pero en el caso del chocolate blanco, el procesamiento al que se somete lleva a perder sus nutrientes y lo convierten más bien en azúcar y grasa.
3. Brotes de soja: Pese a que se considera un alimento sano y muchos médicos lo recomiendan, sus semillas necesitan condiciones de humedad y calor que lo convierten en caldo de cultivo ideal para bacterias. Por eso ocurren tantos casos de contaminación alimentaria en los que el origen son estos brotes. La solución sería hervirlos o sustituirlos por otras verduras crujientes como la zanahoria o el repollo.
4. Tomates en lata: La acidez del tomate hace que la resina utilizada en el revestimiento de la lata aumente el nivel del tóxico Bisfemol A que entra en nuestro cuerpo y afecta nuestro equilibrio hormonal, según Jack, lo que ocasionaría problemas de salud y peso. La recomendación es utilizar tomate envasado en cristal o tetra-brick.
5. Pez espada: El experto David Jack recomienda evitar su consumo por el alto contenido en mercurio así como las prácticas no sostenibles que se utilizan a menudo para pescar este pez. Algunas alternativas: salmón de Alaska, atún del pacífico o channidae.
