2:34 PM | Affascinanti teorie
Infatti le teorie sono tutte molto affascinanti, ma se non vengono verificate da osservazioni o esperimenti, rimangono piacevoli ipotesi che divertono gli scienziati e gli scrittori di fantascienza.Isaac Asimovda Scivola, stella, scivola (Twinkle, Twinkle, Microwaves), su Urania 735, traduzione di Luca Serri

2:15 PM | Podcast: The Venus Zone
This week on the Physics Central Podcast, we take a trip to the Venus Zone. You've heard of the Habitable Zone, yes? That's the region around a star where scientists think a planet would receive just the right amount of radiation to support life. The planet would still need an atmosphere and probably some water, but in the Habitable Zone there's a good chance it would also have a reasonable surface temperature.Now, a group of researchers have defined a Venus Zone, which lies inside the […]

1:41 PM | Cash and Respect
The London School of Economics has a report on a study of academic refereeing (PDF) that looked at the effect of incentives on referee behavior. They found that both a “social incentive” (posting the time a given referee took to turn around the papers they reviewed on a web site) and a cash incentive ($100…

12:53 PM | Sorting water molecules
Not all water is equal - at least not at the molecular level. There are two versions of the water molecule, para and ortho water, in which the spin states of the hydrogen nuclei are different. Researchers have now reported the successful separation of the two forms.

8:06 AM | Graphene accelerates the electro-optic response in ferroelectric liquid crystal displays
Ferroelectric liquid crystal (FLC) display technology holds the promise of fast switching times, a large viewing angle, and high resolution. FLCs have a spontaneous polarization whose direction is perpendicular to the layer. This spontaneous polarization plays an imperative role in the electro-optic switching of FLCs. Researchers have now developed a technique to amplify the spontaneous polarization by doping graphene into FLCs.

5:48 AM | Witness The Singularity AI Nanotech Co-Evolutionary Merger
How is this for some exciting news, straight from the same source as “I Let My Computer Use My Brain” three years ago, but much advanced in the ways artificial intelligence (AI) has integrated itself further so that most anybody can now work with it, or better, play with it and do cutting edge research nevertheless:  read more

4:00 AM | Un potente test per verificare l’esistenza di altre forze della Natura
Secondo il modello standard, le particelle che mediano le quattro interazioni fondamentali sono i fotoni, i bosoni W e Z e i gluoni. Di recente, però, è emerso un nuovo interesse per quanto riguarda la possibile esistenza di una ‘nuova forza’ che, se confermata, potrebbe implicare una estensione del modello standard. Dal punto di vista puramente […]

2:57 AM | Multiscale Structure via Information Theory
We have scienced: B. Allen, B. C. Stacey and Y. Bar-Yam, “An Information-Theoretic Formalism for Multiscale Structure in Complex Systems” [arXiv:1409.4708]. We develop a general formalism for representing and understanding structure in complex systems. In our view, structure is the totality of relationships among a system’s components, and these relationships can be quantified using information […]

2:34 AM | Dirac, Pauli and You
Here is Paul Dirac in October 1927: If we are honest — and scientists have to be — we must admit that religion is a jumble of false assertions, with no basis in reality. The very idea of God is a product of the human imagination. It is quite understandable why primitive people, who were […]

9:03 PM | Mondo 9
Pubblicato a puntate su web, è stato successivamente raccolto in volume da Delos Books. Definito da Graham Edwards un romanzo steampunk (ma non sono completamente d'accordo), deve secondo me molto a un romanzo di grande impatto come Dune di Franck Herbert, con il quale condivide l'ambientazione: un pianeta desertico.Per muoversi e sopravvivere, però, gli esseri umani si devono affidare a navi gigantesche che solcano le dune di sabbia e con una tecnologia così sofisticata, […]

5:35 PM | Bad Graphics, STEM Diversity Edition
There was a article in Scientific American about diversity in STEM collecting together the best demographic data available about the science and engineering workforce. It’s a useful collection of references, and comes with some very pretty graphics, particularly this one, showing the demographic breakdown of the US population compared to the science and engineering fields:…

4:46 PM | Ms. Cherish Goes to the Atheist Meeting
I’ve contemplated writing on this topic for a while.  At the same time, I haven’t wanted to.  Probably because I’m not sure what the point of revisiting this is other than to gripe.  But then I came across this article about misogyny in atheism and decided I was just irritated enough to say something. What’s […]

1:58 PM | Artificial 'beaks' that collect water from fog: A drought solution?
From the most parched areas of Saudi Arabia to water-scarce areas of the western US, the idea of harvesting fog for water is catching on. Now, a novel approach to this process could help meet affected communities' needs for the life-essential resource.
