9:10 AM | Permselective graphene oxide separator for very stable lithium-sulfur batteries
The commonly used separators in battery systems are porous polymer membranes, which separate the two electrodes while having little impact on the transportation of ions through the membrane. Polysulfides generated in a lithium-sulfur system can also diffuse freely through the membranes and react with a metal lithium anode, which results in the degradation of the battery's performance. If a novel, ion-selective but highly permeable separator can be developed, the shuttling of polysulfides and […]

9:05 AM | Wrapping carbon nanotubes in polymers enhances their performance
Scientists developed a technique that 'exfoliates' aggregated clumps of CNTs and disperses them in solvents. It involves wrapping the tubes in a polymer using a bond that does not involve the sharing of electrons. The technique is called non-covalent polymer wrapping.

4:00 AM | Il nostro Universo fa parte di un Multiverso?
Il modello dell’inflazione cosmica, pubblicato da Alan Guth nel 1981 su Physical Review D, e di cui ha scritto successivamente un libro, fornisce una spiegazione alquanto plausibile su diverse proprietà dell’Universo, tra cui la sua uniformità (vedasi principio cosmologico), la sua densità di massa e la radiazione cosmica di fondo. Molte versioni dell’inflazione implicano che il … Continue reading Il nostro Universo fa parte di un Multiverso? […]

1:00 AM | A Networked World (Part 2)
guest post by David Spivak Creating a knowledge network In 2007, I asked myself: as mathematically as possible, what can formally ground meaningful information, including both its successful communication and its role in decision-making? I believed that category theory could be useful in formalizing the type of object that we call information, and the type […]

11:46 PM | Alan Stern on Pluto’s Wonders, New Horizons’ Lost Twin, and That Whole "Dwarf Planet" Thing
You don't have to wonder what is on Alan Stern's mind. The planetary scientist and former NASA associate administrator is a relentless champion of all things Pluto; he is both the principal investigator and the prime mover behind the New Horizons mission, which will fly past Pluto and its moons this July 14. In advance of the encounter, Stern's passion is building to a white heat, and he is letting everyone know it. The excitement is infectious. Pluto is looking far more interesting than

9:16 PM | Neutrinos rarely interact, but watch them hit the Nova detector here!
We hoped to restart the Large Hadron Collider last week but it didn’t happen. However, particle physics marches on...I would love to claim that the last couple of weeks of silence from the Life & Physics pages were due to me being occupied at CERN with a superconducting spanner, getting the Large Hadron Collider ready to roll again. This has not been the case. As I told Jonathan Webb at the BBC, the accelerator work is carried out at CERN by accelerator physicists and engineers, in a […]

The NASA Orion program managers Mark Geyer and Mike Hawes discussed the lessons they learnt from the crew capsule’s first test flight in December 2014 with Space.com, which published the interview on March 29. The propulsion, guidance and navigation systems had worked well, but the splashdown airbags didn’t, while they also found the heat-shield’s performance […]

11:38 PM | In Praise of NASA's Ambitious Asteroid Grab
If you pay attention to news about space exploration, you may have seen some skeptical stories about NASA's proposed Asteroid Redirect Mission. (And even if you don't follow such things, you might well have been dismayed by headlines announcing a "less ambitious asteroid mission" that is "unlikely to get funded.") This is not another one of them. I think the asteroid mission is a cool idea, and an important one. I think it will advance the cause of space exploration in several meaningful
