3:46 PM | Researchers patent a nanofluid that improves heat conductivity
Scientists have developed and patented a nanofluid improving thermal conductivity at temperatures up to 400 C without assuming an increase in costs or a remodeling of the infrastructure. This progress has important applications in sectors such as chemical, petrochemical and energy, thus becoming a useful technology in all industrial applications using heat transfer systems such as solar power plants, nuclear power plants, combined-cycle power plants and heating, among other.

3:36 PM | Inflazione infinita e fine del tempo
Come saprete i dati di BICEP che sembrava dovessero confermare l'inflazione cosmica e le onde gravitazionali primordiali hanno subito una verifica negativa. Come spiegano molto bene Amedeo e Sandro, l'interpretazione dei risultati è stata completamente ribaltata dalle analisi di Planck.Uno degli aspetti che, con quell'annuncio di metà aprile, non avevo trattato ma che mi sarebbe piaciuto era la questione dell'inflazione infinita. Questa ipotesi teorica venne introdotta da Alan […]

3:17 PM | Network Theory Seminar (Part 3)
  This time we use the principle of minimum power to determine what a circuit made of resistors actually does. Its ‘behavior’ is described by a functor sending circuits to linear relations between the potentials and currents at the input and output terminals. We call this the ‘black box’ functor, since it takes a circuit: […]

12:10 PM | Our Universe in Color
Today we released six new images from Chandra’s vast data archive. Each one of these astronomical images combines X-rays from Chandra with data from telescopes that detect different types of light such as infrared, radio, and visible light. You may notice that the color maps in this new collection of images are not the same. For example, in the image of PSR B1509-58, X-rays from Chandra are colored blue, while in NGC 4736 the X-rays are gold. Why is this? The answer is that each […]

12:05 PM | Chandra's Archives Come to Life
Every year, NASA's Chandra X-ray Observatory looks at hundreds of objects throughout space to help expand our understanding of the Universe. Ultimately, these data are stored in the Chandra Data Archive, an electronic repository that provides access to these unique X-ray findings for anyone who would like to explore them. With the passing of Chandra's 15th anniversary in operation on August 26, 1999, the archive continues to grow as each successive year adds to the enormous and invaluable […]

That’s “Mass” as in Massachusetts, not the stuff associated with the Higgs field… specifically, North Adams, MA, where I’ll be this Saturday night, October 25th, at the Secret Science Club screening of Particle Fever. This will be at the MASS MoCA, tickets here. The Secret Science Club is a regular gathering in New York City…

10:51 AM | Ultra-stretchable silicon for flexible electronics (w/video)
Researchers have demonstrated ultra-stretchability in monolithic single-crystal silicon. The design is based on an all silicon-based network of hexagonal islands connected through spiral springs. The resulting single-spiral structures can be stretched to a ratio more than 1000%, while remaining below a 1.2% strain. Moreover, these network structures have demonstrated area expansions as high as 30 folds in arrays. This method could provide ultra-stretchable and adaptable electronic systems for […]

Un gruppo di astronomi guidati dai colleghi del Max Planck Institute for Astronomy hanno realizzato la prima mappa tridimensionale dell’Universo distante che risale ad appena 3 miliardi di anni dopo il Big Bang. La mappa, costruita a partire dai dati raccolti con i telescopi del Keck Observatory, si estende per 100 milioni di anni-luce e fornisce preziosi indizi sulle strutture […]
