A New Paint Made From Glass Reflects the Sun To Cool Down Cars and Homes - Gizmodo

The sun’s harsh rays don’t just turn metal surfaces into flying pans, they can also accelerate deterioration and corrosion, and make it harder to keep structures cool. So researchers at Johns Hopkins Applied Physics Laboratory created a new type of paint made of glass that reflects those rays away.

The sun is the enemy of traditional paints, which are made from polymers. The sun’s ultraviolet rays degrade polymers, which is why the paint on the side of a building will slowly fade over time. And while it degrades, it releases volatile compounds that can harm the environment.

But the paint developed by Jason J. Benkoski and his team at Johns Hopkins is resistant to the fading that affects traditional paints. Made from a mixture of silica (one the main ingredients of glass) and potassium silicate so it isn’t brittle, it starts off as a liquid so that it can be brushed or sprayed onto a surface. When it hardens in a few hours, it’s almost as hard as rock. Most outdoor paints will only last a few years in the sun, but this new type of glass paint could easily survive for centuries without fading or cracking, its creator claims.

Construyen una réplica del coche fantástico con piezas impresas en 3D


¿Tienes un Pontiac Firebird de sobra por ahí? Si la respuesta es afirmativa, solo necesitas una impresora 3D para convertir ese bólido en el mismísimo Kitt, el automóvil parlante de Michael Knight en la serie Knight Rider (El coche fantástico). Eso es a lo que se han dedicado tres diseñadores franceses, y el resultado es pura nostalgia de los 80.

Al principio, Nicolas Rambaud, Clément Bonfils, y Patrick Masson intentaron construir su réplica mediante métodos más convencionales, pero fabricar las piezas a medida era un proceso largo y costoso. La impresión 3D ha abierto una inusitada vía de trabajo para estos artistas que han culminado por fin su proyecto después de tres años.

El Knight Industries Two Thousand que han fabricado es idéntico al de la serie por dentro y por fuera. Hasta tiene algunos trucos sorprendentes como las aletas móviles del modo persecución y hasta una placa de matrícula giratoria para despistar a la Gendarmerie. Todavía no tiene Turbo Boost, pero solo hay que darles tiempo a estos ingeniosos diseñadores.

Here Are the True Radiation Dangers in Your Environment
People are terrified that they’re being exposed to radiation all the time, whether from distant nuclear accident or the mobile devices snuggled against their heads. Generally, they are wrong. Here are the most radioactive objects in the world around you, and the truth about which ones cause health problems.

This Man Is About to Put a Robot in Your Pocket

What will it take for robots to become as common in our homes and daily lives as smartphones, TVs, and computers? Ask roboticist Tomotaka Takahashi. The famous Tokyo professor aims to be “the Steve Jobs of robotics,” by moving away from technical specs and emphasizing design, as well as pure bot charisma.

Pagan News Beagle: Earthy Thursday, August 27

Wildfires sweep the Pacific Northwest, sending clouds of toxic smoke into the air. Oslo construct a special “highway” just for bees. And FiveThirtyEight’s Christie Aschwanden takes a look at the hard work that goes into scientific research. It’s Earthy Thursday, our weekly segment on the Earth and science-related news. All this and more for the Pagan News Beagle!

Esto es lo qué pasa al disolver tabletas efervescentes en gravedad cero


Nada es igual en el espacio, y disolver una tableta efervescente como la de un antigripal común y corriente no es una excepción. Desde la ISS nos llega este curioso vídeo en el que el astronauta Terry Virts nos muestra precisamente eso: cómo se disuelve una tableta efervescente en el espacio. Además, es uno de los primeros vídeos de la ISS en glorioso 4K.

No es que el experimento sea una demostración crucial de dinámica de fluidos en gravedad cero ni nada por el estilo. Simplemente es que los astronautas de la ISS tienen una nueva cámara Red Epic Dragon capaz de grabar en súper alta definición y están como un niño con un juguete nuevo, grabando todo lo que se les ocurre en 4K. El hecho de que ahora YouTube soporte esa definición nos augura sensacionales vídeos de ciencia y curiosidades a bordo del laboratorio en órbita.

La Red Epic Dragon en realidad es capaz de grabar a 6K y 300 fotogramas por segundo. Más allá de pasarlo bien en YouTube, la nueva cámara será de gran ayuda para rodar en detalle los experimentos o para mostrar nuevas imágenes de nuestro planeta. La cámara llegó a la estación en enero de este año a bordo de una cápsula Dragon de SpaceX.

Was Vandalism Of HitchBOT A Sick Prank By Internet Vloggers? (IMAGES/VIDEO)

HitchBOT was a robot created by Port Credit, Ontario professors Dr. David Smith and Dr. Frauke Zeller. The robot was set on his first adventure from Halifax, Nova Scotia on July 27 of last year, in a grand experiment to see how people would react to a hitchhiking robot. It hitchhiked its way across Canada, traveling over 10,000 km (6,213 miles) with 19 drivers over 21 days, finally ending up in…

Extraordinary data analysis of the Ashley Madison leaked accounts reveals that most women registered never used the service - many of them didn’t even exist

Gizmodo’s Annalee Newitz took a deep dive into Ashley Madison’s data to find out that the company’s business was really to sell fantasies, not affairs. 

There were far too few real female users for that:

What I discovered was that the world of Ashley Madison was a far more dystopian place than anyone had realized. This isn’t a debauched wonderland of men cheating on their wives. It isn’t even a sadscape of 31 million men competing to attract those 5.5 million women in the database. Instead, it’s like a science fictional future where every woman on Earth is dead, and some Dilbert-like engineer has replaced them with badly-designed robots.

The data reveals there were 32 million men registered against 5.5 million women. However, Newitz’s finds that Ashley Madison’s millions of men interacted with, well, non-existing women:

…the more I examined those 5.5 million female profiles, the more obvious it became that none of them had ever talked to men on the site, or even used the site at all after creating a profile. Actually, scratch that. As I’ll explain below, there’s a good chance that about 12,000 of the profiles out of millions belonged to actual, real women who were active users of Ashley Madison.

Newitz work is a fascinating and compelling data journalism read. 

Ashley Madison was no cheater’s playground. It was a fantasy scam that exploited the male ego.
