Magnet Boy of Croatia: gadgets stick to his chest (big photo gallery)
Young Ivan Stoiljkovic poses for pictures with a Samsung Galaxy Tab stuck to his chest in front of his home near Koprivnica, about 62 miles (100km) north of Croatia’s capital city, Zagreb, on May 12, 2011. Ivan, 6, is purported to posess an extraordinary and seemingly magical talent: the ability to attract metallic objects — from spoons to heavy frying pans — to his body. He is said to be able to carry up to 25 kg of metal stuck to his torso. Ivan’s family also claims that his hands can emit heat and his mysterious ability has also given him healing powers. “Medical checkups so far have reaped inconclusive results,” reports Reuters. More images follow, in which Ivan “attracts” cutlery, cookware, an iron, and other metallic objects. In the image below, his grandfather tosses coins at his chest. Surely this isn’t a hoax!

New York City in Black & White
34th Street. Note the building with the billboards who wouldn’t sell to Macy’s so they built around it.
There’s something about these old photos of New York that continually draws me back. I actually posted some other images from this collection by Berenice Abbott back in 2009 during the thick of the economic meltdown, which sadly many people are still dealing with. Abbott’s photos — which were commissioned by the WPA and are part of the New York Public Library’s collection — cover a large swath of New York life during the mid-1930s, another very difficult period in our country’s history.
Even though you may have seen these before, these photos are never a let down. To me it is interesting to see how much the city has changed and of course, how it hasn’t. You can see the complete set here and can own the book too, should you desire.
Web Standards Update for Visual Studio 2010 SP1
As the HTML5 and CSS3 specifications mature we will make updates available accordingly to ensure that ASP.NET web developers always have the latest standards to work with. This is at the same time an invitation to report any bugs or features you would like to see in future updates. Please write a comment with any bugs or suggestions.
Now let’s take a look at some of the features.
HTML 5
WAI-ARIAThe WAI-ARIA standard enables web developers to make their websites more accessible to e.g. screen readers. This update contains a rather comprehensive support for WAI-ARIA by adding all the aria-* attributes along with new intellisense for the role attribute.
The aria-* attributes shows up in the intellisense list as well as the values.
Microdata
HTML 5 has an additional way of adding meaning to the markup called Microdata. This allows web developers to mark different elements with meta data that is readable by e.g. search engines. Bing, Google and Yahoo are all supporting Microdata and more specifically the schema.org vocabularies. This update will therefore add intellisense to the most popular vocabularies including schema.org and data-vocabulary.org.
If you are interested in search engine optimization you might find this Microdata support particularly useful.
CSS 3
If you don’t get intellisense after installing the update, you might have to select the CSS 3.0 schema manually on the Style Sheet toolbar.
Multi-columns
It is much easier to read lines of text that aren’t too long. Newspapers have always kept their columns rather narrow and with CSS 3 this becomes possible very easily on websites as well. This update brings full intellisense for both properties names and values for multiple columns.
For more info on multi-columns, check out this introduction to to the CSS3 Multi-Column Module.
Border-radius
There is no way around this. It’s impossible to talk about CSS3 without giving The Rounded Corners™ example because it is the quintessential CSS3 feature. The CSS3 support brought by this update does of course contain full support for rounded corners aka. border-radius.
Animation, transitions and transforms
CSS3 introduces some new and features that could seem a little complicated to learn. With both validation and intellisense to guide you through all these new features, it has never been easier to explore what CSS3 has to offer.
JavaScript
The update to JavaScript is very comprehensive. You will immediately start noticing a lot more values in the intellisense.
Geolocation
One of the most talked about features of modern web browsers is their location awareness. In JavaScript you can hook into this knowledge by using the geolocation API. This is also supported in all newer browsers.
DOM storage
Using the DOM storage mechanisms you can eliminate the need for cookies to persist user data and settings. Both localStorage and sessionStorage are fully supported by this udpate.
Read an introduction to DOM storage.
Also notice…
The HTML 5 support included in SP1 added intellisense and validation for a lot of new elements such as the and elements. However, there were bugs and one of them were the error you would see when adding elements inside elements. This is being fixed by this update so you now also get intellisense for the element. The type attribute is also no longer required in <script> elements.
We also added missing elements such as <bdi>, <s> and <u> and a lot of new attributes such as dropzone for drag ‘n drop.
Known issues
Though this update contains a lot of new CSS3, HTML5 and JavaScript support, there are certain things that we haven’t been able to do. Since we don’t make any changes to the running code of Visual Studio, we are not able to change the way CSS, HTML and JavaScript gets parsed and validated. That means that even though we are continuing to bring you updates as the W3C standards changes, we will not be able to get it 100% right in Visual Studio 2010.
We do encourage you to report any bugs you find to us directly as a comment here on this blog post. We do take this very seriously and want to get as close to 100% as we possibly can.

Tashi Wada for Stephan Mathieu

The concert was held as part of the “Alterminimalismes” concert series at the Collège des Bernardins (Paris).
La clave parece estar en el interior
Esos pacientes, llamados amplios neutralizadores, presentan anticuerpos capaces de anular una gran variedad de distintas cepas del VIH, tal y como señala una investigación española que se acaba de dar a conocer en las páginas de la revista ‘Journal of Virology‘.
Cada vez está más claro que una futura vacuna para prevenir la infección por el VIH debe generar una enorme respuesta inmune, con anticuerpos capaces de neutralizar diversas cepas de virus, como hacen las vacunas de la gripe, la polio, la rubeola y otras enfermedades infecciosas.
Esos anticuerpos de amplio espectro, que hemos observado también en pacientes que ya estaban recibiendo tratamiento antirretroviral, son un reflejo de lo que debe ser una futura vacuna contra elVIH. Si entendemos bien cómo funcionan, lograremos reproducir ese tipo de respuesta como en un espejo
Comenta el doctor José Alcamí, del Instituto de Salud Carlos III y uno de los firmantes del trabajo.
Hasta ahora se pensaba que esto no era posible de manera natural; pero en los últimos dos años, tres grupos diferentes hemos observado que sí, que existen pacientes seropositivos que generan de manera natural anticuerpos de amplio espectro
Explica por su parte el doctor Josep María Gatell, del Hospital Clínic de Barcelona, al que pertenecían los 364 pacientes de este ensayo.
Además, y aquí radica la novedad, ese fenómeno se ha observado por primera vez en pacientes que ya habían iniciado la terapia antirretroviral y que presentaban una pequeñísima carga viral, algo impensable hasta ahora.
Para que los anticuerpos que genera el organismo contra el VIH sean eficaces, además de reconocer varias cepas diferentes, también deben identificarlas con mucho grado de afinidad.
Gran parte de esa afinidad se logra con la replicación constante del virus en las células humanas, por lo que parecía un fenómeno impensable en pacientes con poca cantidad de virus (como los que ya están en tratamiento).
Sin embargo, a pesar de esa creencia, también se ha hallado anticuerpos de amplio espectro en pacientes que llevaban mucho tiempo con la infección controlada.
Su hallazgo no equivale automáticamente a disponer de una vacuna contra el sida, aún queda trabajo por delante, coinciden Alcamí y Gatell. En los próximos años habrá que seguir trabajando con esos anticuerpos naturales y tratar de imitarlos de alguna manera en el laboratorio.

En este baño público ruso ni las bombas podrán interrumpir tu inspiración
En este baño público ruso ni las bombas podrán interrumpir tu inspiraciónYa es fome que la naturaleza haga su llamado cuando te encuentras lejos de tu casa. Ya sabes: el dicho versa que el trasero se cohíbe en baño ajeno. Pero peor es cuando estás en un recinto público y hay un desfile de inoportunos que no permiten que te concentres. Y acaso ¿podría llegar a ser aún peor si por esas cosas de la vida más encima se produce un ataque terrorista con bomba mientras intentas hacer lo tuyo? Definitivamente, no.
Pero los rusos ya tomaron cartas en el asunto y comenzaron a desarrollar baños públicos resistentes a ataques vandálicos y terroristas. Por eso, antes de fin de año ya podrías ir a uno y despreocuparte por completo sabiendo que nada podrá interrumpir tu labor. Están hechos de concreto fibroso ultra resistente, acero y plástico reforzado. Y para estar más cómodo en los inclementes inviernos moscovitas, tiene incorporado un sistema de calefacción.
A los 30 minutos suena una alarma y se abre la puerta, obligándote a salir, pero conozco poca gente que sea capaz de tomarse tanto tiempo, por lo que no debiera ser un problema.

El Universo en tus manos
Queridos amigos de Xataka Ciencia, ¿nunca habéis deseado tener el control del Universo? o ¿sentiros “todopoderosos” y crear uno nuevo?. Vuestras suplicas han sido escuchadas, os presento (a los que no lo conozcan) el juego del año: “Universe Sandbox“.
Desarrollado por GianArmy, ‘Universe Sandbox‘ es una interesantísima herramienta con la que podemos jugar a ser Dios con el universo en nuestras manos, alterando órbitas de planetas, creando agujeros negros, haciendo que las galaxias converjan y se autodestruyan entre sí.
Todas estas posibilidades son solo un bocado de lo que podremos probar en su versión freeware, descargable desde su página web (la versión completa tiene un coste de unos 20 $).
Lo bueno es que, a pesar de todo, los diseñadores del juego han tenido mucho cuidado en crear una interfaz relativamente sencilla, inspirada en otro tipo de juegos de estrategia y simulación. De ahí que mover planetas y ver cómo la gravedad los atrae entre sí, o enviar a la Tierra desde el Sol hasta Orión, sea tan sencillo como un clic y un arrastre de ratón.
A diferencia de otros juegos, “Universe Sandbox“, realmente le permite jugar con la física y descubrir cómo funcionan las cosas. Hay un sinfín de detalles y tantas cosas para jugar. Es interesante ver los efectos que, incluso pequeños cambios, pueden tener.
Como nota de color final, cabe destacar que a pesar de su fin didáctico – lúdico, “Universe Sandbox“ ha sido programado para ser compatible con gafas 3D anaglíficas y televisores DLP 3D. ¿ya que jugamos con el universo, por qué no hacerlo con una calidad de imagen de lujo?
Ve el video en el sitio original.
¿A qué esperas? ¡Conviértete en el “Amo del Universo” hoy!

Roscoe Mitchell’s Day Off
If you’re reading this, you probably know it’s a busy time for jazz. So I’ll keep this brief. On Sunday evening at 6 p.m., I’ll be moderating a conversation with saxophonist, composer and AACM heavyweight Roscoe Mitchell, at Settlement Music School in Philadelphia. The talk (which is free) will precede an 8 p.m. performance by his Sound Ensemble (which isn’t). It’s part of a weekend-long Mitchell residency, within a larger AACM series, presented by Ars Nova Workshop.
Roscoe Mitchell is, of course, a fiercely individual thinker and creative force, and while I haven’t yet had the honor of interviewing him, I have heard him speak on a few occasions. The most memorable of these was during a symposium in Guelph, Ontario, in 2005. That was for a 40th-anniversary celebration for the AACM; during the same weekend, Mitchell also performed with the Art Ensemble of Chicago and in duo with Pauline Oliveros. (I wrote about it in JazzTimes.)
Incidentally, the other night I was at the Vision Festival speaking with Yulun Wang of Pi Recordings, which has released albums by the Art Ensemble as well as Mitchell’s collaboration with two fellow AACM stalwarts, pianist Muhal Richard Abrams and George Lewis. The subject of AACM commemoration came up, and I naturally mentioned the classic John Hughes film Ferris Bueller’s Day Off. Yulun didn’t know what I was talking about, which led me to believe that this bit of trivia might not be as well-known as I’d thought.
A few years ago this movie was on TV and I caught a little detail in the Chicago parade scene above. Look at the banners that go by during Matthew Broderick’s slow ride on the float. It’s hard to make out in this grainy YouTube transfer, but they read “AACM 20,” next to an image of a bassist — Fred Hopkins? Anyone have the DVD? Anyone?
This makes sense, as the movie was filmed in 1985, when the city of Chicago would have been celebrating the AACM’s 20th anniversary. So we have serendipity and location shooting to thank for the only mention of the Association for the Advancement of Creative Musicians in a top-grossing Hollywood movie. (Of course I’m not counting the Anthony Braxton cameo, as a blackjack dealer, in Ocean’s 12.)
No, I do not plan on discussing this with Roscoe Mitchell.
While we’re on the subject of jazz commemoration, though, I should also note that tomorrow, Saturday, marks the 15th annual Jazz Journalists Association Jazz Awards. It’s at City Winery, and I believe tickets are still available. In addition to the bestowing of awards, the event will feature performances by Randy Weston, Wallace Roney, Gregory Porter, Jane Bunnett and others. I’ll be there. How about you?
Anyone? Anyone? Bueller? …Bueller? …Bueller?

Burgers, Burgers, Burgers Everywhere
There is something ethereal, yet unpretentious and simple about the burger. At its Ron Swanson most pure form – it’s meat on a bun, put ketchup on it if you like, I don’t care. It can be dressed up, shaken down, deconstructed or completely up-ended. My friend the Burger Beast is even making a living off the damn things.
That’s why this weekend, the Brickell Life crew decided to throw down an Iron Chef style Battle Burger. Basically, we were all just looking for some reason to drink some beers and wine by the pool and Biscayne Bay, and well, burgers just seem to fit the mid-summer vibe.
Your’s truly, Brickell Life, managed to pull off the victory with a nod to the classic bacon cheeseburger, but topped off with a fried quail egg – basically grown up people’s mayonnaise. Other entries included dry-aged ribeye burgers topped with decadent bone marrow, truffled chuck burgers with seared foie gras, and lamb/feta burgers with greek yogurt sauce. Needless to say, nobody left hungry and three-year olds ate bone marrow alongside hot dogs and chips.
Pictures of some of the food and good times are below along with a quick recipe recap of our winning burger. Summer living in Miami does not get any easier. Much love to all who attended, cooked and watched the sun curve over Biscayne Bay.

Classic Bacon Cheeseburger Sliders
Ingredients:
Beef – 50% ground boneless short rib and 50% ground brisket. Buy equal amounts of each cut of beef.
Kosher salt
Cracked black pepper
White American cheese
Red leaf or butter lettuce
Plum tomato
Applewood smoked bacon
Quail eggs
Challah or brioche slider rolls/buns
Directions:
Remove silver skin and trim any excess fat from both cuts of meat. Cut both kinds of beef into approximately 1-inch cubes and keep in separate bowls/bags based on individual cuts of beef. Place each bowl/bag into the freezer for approximately 15-20 minutes along with the blade of your food processor. If you have one of those fancy grinding attachments for a Cuisinart mixer, you can go that route, but a simple food processor will do the trick for great backyard burgers. Then place meat cubes, still keeping them separate, into food processor and process in small batches, ideally no more than 1/2 pound at a time to ensure an even grind. Pulse in short 1-to-2 second bursts until the desired consistency is achieved, usually about 10-15 pulses.
Its important to pulse instead of letting the food processor run because pulsing tends to distribute the meat more evenly and avoids the excess heat that the blade can produce while running full blast, which can turn your beef into melted fat mush. Not good eats. Once you’ve ground your beef, you can loosely combine both cuts of ground beef in a large bowl and set back in the fridge until you’re ready to make your patties. Grind fresh if possible and cook that day. Sure you can save it and even freeze the ground beef, but the sizzle of fresh ground beef is where burger magic tends to happen.
When you’re ready to shape the patties remember – don’t pack. Slapping that burger around is bad for business. Just shape a loose ball of meat in your hand and just press gently to form a patty. The more you pack, the denser the burger and the more potential for shrinkage. Shrinkage does not benefit anyone, come on now.
Aim for patties about a 1/2 inch thick. Season liberally with kosher salt and cracked black pepper only and only right before your grill. It will help give them a nice crust, while not drawing out precious juices before hitting the cooking surface. Grill them over the barbecue or sear them on cast iron or on a griddle. Never squish your burgers with a spatula, which forces the juices out. Only turn the burger once. I like my burgers a perfect medium. Cook to your tastes. If your burgers sometimes bulge in the middle, just make a little indentation in the middle of the patty before you cook so a nice even burger forms after cooking. There is some scientific explanation based on the laws of quantum physics as to why your burger does this, but I’m too lazy to look it up on the Google machine right now. Feel free to do that research on your own time.
You can certainly top your burgers however you want, but if you want to mimic my Brickell Life winning slider above, make sure you’re frying quail eggs after the first flip of the burger to ensure everything is hitting the bun warm. We used quail eggs because burgers were slider sized. Otherwise, regular eggs will work on a full-sized version. You can cook the bacon before the burgers to make prepping easier, but just make sure you bring it up to temperature so its warm before hitting the plate. Also, a toasted bun is a nice touch. Lightly butter the inside of each bun and grill ever so slightly so the inside of the bread is nice an toasty and acts as a barrier to soft, squishiness of the rest of the bread. I like challah or brioche for my burgers. Great buttery, sweet, eggy bread is the way I get down to burger business. Place the cooked bacon on to the burger and melt the cheese on the burger after you flip the patty. To plate, I like bottom bun, burger w/ bacon and melted cheese, lettuce, tomato, fried egg and the top bun just tilted off to the side so everyone sees what they are getting themselves into.
You can add ketchup and stuff if you like, but I’m going to be honest, your burger won’t need it if you seasoned it liberally and used really good ingredients.
That’s about it. Most important part is the beef. It’s the star of the show, so if you take your time and use good ingredients, it will probably go down pretty smooth with a cold beer on a Sunday afternoon.
