Mood rings may have been a fleeting fad of the 1970s, but researchers at Vanderbilt University are using the basic concept as a means of detecting damage in failing infrastructure before it becomes critical.
There has been a lot of digital ink spilled over the recent paper on the reactionless thrust device known as the EMDrive. While it’s clear that a working EM Drive would violate well established scientific theories, what isn’t clear is how such a violation might be resolved. Some have argued that the thrust could be an effect of Unruh radiation, but the authors of the new paper argue instead for a variation on quantum theory known as the pilot wave model.
One of the central features of quantum theory is its counter-intuitive behavior often called particle-wave duality. Depending on the situation, quantum objects can have characteristics of a wave or characteristics of a particle. This is due to the inherent limitations on what we can know about quanta. In the usual Copenhagen interpretation of quantum theory, an object is defined by its wavefunction. The wavefunction describes the probability of finding a particle in a particular location. The object is in an indefinite, probabilistic state described by the wavefunction until it is observed. When it is observed, the wavefunction collapses, and the object becomes a definite particle with a definite location.
While the Copenhagen interpretation is not the best way to visualize quantum objects it captures the basic idea that quanta are local, but can be in an indefinite state. This differs from the classical objects (such as Newtonian theory) where things are both local and definite. We can know, for example, where a baseball is and what it is doing at any given time.

Time travel could be possible, says a group of physicists who’ve come up with a new interpretation of our universe, says the Sun U.K.
Professor Howard Wiseman and Dr. Michael Hall from Griffith University’s Centre for Quantum Dynamics, and Dr. Dirk-Andre Deckert from the University of California, say there are many universes, including identical ones to ours, that “influence one another through quantum mechanics.” The theory is called the “Many-Worlds Interpretation.”
What this means is that travelling through time within our universe is conceivable, says the Sun.

It seems like bots are everywhere these days, with more and more popping up every day. From bots that help us tag people on Facebook to simple Twitter bots that respond to our tweets.

What generates voltage when you warm it up, push on it, or blow on it?
Get your mind out of the gutter. The correct answer is polyvinylidene fluoride, a material NASA researchers have refined for use in morphing aircraft that shapeshift in response to their environment. But wait! There’s more: It can also kickstart the human body’s healing process.
Because of its potential to heal the world and make it a better place, the polymer’s inventors, Mia Siochi and Lisa Scott Carnell, have now turned it over to the public through NASA’s Technology Transfer Program. Through that process, companies license NASA technology for cheap and turn it into products to sell to non-astronauts. But transforming space stuff into Earth stuff isn’t always smooth. Turned-over technology can get lost inside the catalog, stall out in the bowels of a company, or become part of a product the original inventors wouldn’t approve of.

A Marinha dos Estados Unidos fez uma parceria com cientistas do Massachusetts Institute of Technology (MIT) para criar uma rede de sensores barato, portátil que monitora o consumo de energia de cada um dos seus dispositivos domésticos.
O sistema consiste de cinco sensores de tamanho selo-postais colocados acima ou perto de linhas elétricas que entram na casa, que podem identificar cada luminária ou aparelho com base em seu uso de energia. Ele canaliza os dados para um aplicativo em tempo real, permitindo que as pessoas possa ver quando sua geladeira consome para um ciclo de degelo, por exemplo.
“Já existem maneiras de monitorar o uso de energia doméstico, mas elas envolvem a contratação de um eletricista licenciado ou cortando linhas de energia ou tubos caro para anexar, equipamento especializado,” professor de engenharia do MIT e chefe do projeto Stephen Leeb disse em um comunicado de imprensa. “Com o nosso sistema, é possível instalar sensores sem contato usando laços zip ou mesmo velcro, e usar o processamento de sinal para medir o consumo de energia. Também poderia servir como uma maneira de dizer quando o equipamento precisa de manutenção ou substituição.”
