Victor De Schwanberg/SPLScientists have come closer than ever before to creating a laboratory-scale imitation of a black hole that emits Hawking radiation, the particles predicted to escape black holes due to quantum mechanical effects.The black hole analogue, reported in Nature Physics1, was created by trapping sound waves using an ultra cold fluid. Such objects could one day help resolve the so-called black hole ‘information paradox’ - the question of whether information that […]

Source: NPRAs I noted in my post on Sequestration, we are truly reaping what we've sown to the wind of libertarian philosophy and austerity."Tightening one's belt" is painful in actual practice, but makes for a good soundbite for politicians that get free healthcare and a six-figure salary for working less than one-third of everyone else's very busy year.A nurse has been infected; that affects me as I have relatives - a young son in college in particular - in the Dallas area. Yet, as I've […]

10:34 AM | Slippery when dry: Graphene proves a long-lasting lubricant
While researchers have found many materials that help to reduce friction, conventional lubricants often have chemical limitations. A recent analysis has identified the properties of a newer, exceptionally wear-resistant substance that works in a broader range of environments.

I’m hunting astwonomical objects Life in the Quiet Zone: West Virginia Town Avoids Electronics for Science Scientists who use some of the world’s most advanced instruments can’t use a microwave oven to heat their lunch. And then there was the time astronomers were baffled by a mysterious distortion of their data. They had a laugh [...]

7:40 AM | Graphene laminate drastically changes heat conduction of plastic materials
Graphene laminate - multilayer stacks of graphene layers piled on top of each other - is a promising material for thermal coating applications. Researchers have investigated thermal conductivity of graphene laminate films deposited on PET substrates. They found that the compressed laminates have higher thermal conductivity for the same average flake size owing to better flake alignment. This shows a possibility of up to 600-times enhancement of the thermal conductivity of plastic materials by […]

4:00 AM | Il ‘quarto’ neutrino rimane elusivo
Il gruppo internazionale formato da 200 ricercatori che lavorano all’esperimento sull’oscillazione dei neutrini, noto come Daya Bay Collaboration, hanno pubblicato i primi risultati sulla ricerca di una particolare particella, detta neutrino “sterile”, che potrebbe rappresentare un possibile ‘quarto’ tipo di neutrino al di là dei tre neutrini già noti. L’esistenza di questa ipotetica particella, se […]

The younger son occasionally has band lessons after school.  Recently, I picked him up and he said that his band teacher hadn’t been in her office when he was supposed to have his lesson.  The next comment surprised me. You know, in an alternative universe, I forgot my instrument but she was in her office. […]

Last time we came up with a category of labelled graphs and described circuits as ‘cospans’ in this category. Cospans may sound scary, but they’re not. A cospan is just a diagram consisting of an object with two morphisms going into it: We can talk about cospans in any category. A cospan is an abstract […]

7:14 PM | Massive Study Shows How Languages Change
Originally published: Sep 30 2014 - 7:00pm, Inside Science News ServiceBy: Joel N. Shurkin, Contributor(Inside Science)-- More than 100 years ago, the playwright Oscar Wilde had one of his British characters say that England and America "have everything in common nowadays except, of course, language.” It turns out, according to linguists, he was almost right. But lately, the two languages are getting closer.Languages change over time -- some faster than others. Some reflect changes in the […]
