10:04 AM | Attempting to solve the mystery of why Ag-Rh alloy nanoparticles have a similar property to palladium
Scientists have made the first observation of the electronic structure in silver-rhodium (Ag-Rh) alloy nanoparticles to investigate why the alloy possesses a hydrogen absorbing/storage property like palladium does, given that bulk Ag and Rh do not form an alloy, and that neither element alone is a hydrogen absorbing/storage metal.

8:46 AM | A nanorobotics platform for nanomanufacturing
The complexity and high cost of the state-of-the-art high-resolution lithographic systems are prompting unconventional routes for nanoscale manufacturing. Inspired by natural nanomachines, synthetic nanorobots have recently demonstrated remarkable performance and functionality. Nanoengineers now have invented a new nano-patterning approach, named , which translates the autonomous movement trajectories of nanomotors, or nanorobots, into controlled surface features that brings a twist to […]

8:00 AM | Déjà Vu All Over Again
The man who keeps America on time Reminiscent of yesterday’s video — our chief scientist saying similar things, mostly as a proxy for the efforts of my hard-working colleagues (and me). You get a nice view of our wonderful library, though our wonderful librarians are out of view. I should point out that when Chris [...]

4:00 AM | APEX osserva una ‘metropoli galattica’ in formazione
Grazie ad una serie di osservazioni condotte con il telescopio APEX, che sta per Atacama Pathfinder EXperiment, gli astronomi hanno realizzato le immagini di un giovane ammasso di galassie in formazione che si trova ad oltre 10 miliardi di anni-luce, trovando che gran parte delle regioni di formazione stellare in atto non sono solamente nascoste dalla polveri ma avvengono in […]

  I’m giving a short 30-minute talk at a workshop on Biological and Bio-Inspired Information Theory at the Banff International Research Institute. I’ll say more about the workshop later, but here’s my talk: • Biodiversity, entropy and thermodynamics. Most of the people at this workshop study neurobiology and cell signalling, not evolutionary game theory or […]

6:15 PM | Early Universe's Room Temperature Could Have Supported Life
Originally published: Oct 20 2014 - 4:15pm, Inside Science News ServiceBy: Ker Than, Contributor(Inside Science) -- Life in the universe could be much older than previously thought, forming as early as fifteen million years after the Big Bang, according to a provocative new idea proposed by a Harvard astrophysicist.In this scenario for the early universe, rocky planets born from the dregs of massive, primordial stars would have been warmed by the heat of a radiation that permeated all of space, […]

6:10 PM | Everything you wanted to know about inflation, but were afraid to ask
Well, my upcoming class is unlikely to cover everything. After all, there’s a lot we still don’t know about cosmic inflation, including whether it actually happened or not. According to some theories, the Universe expanded very rapidly right after the Big Bang, which would explain a lot of the odder features of the cosmos as […]

6:08 PM | Prostate cancer, kidney disease detected in urine samples on the spot
New device screens for kidney disease, prostate cancer on the spot. The tiny tube is lined with DNA sequences that latch onto disease markers in urine. While healthy samples flow freely, a diseased sample gets clogged and stops short of the mark.

6:01 PM | Watching the hidden life of materials
Scientists have succeeded in simultaneously observing the reorganizations of atomic positions and electron distribution during the transformation of the 'smart material' vanadium dioxide from a semiconductor into a metal - in a timeframe a trillion times faster than the blink of an eye. This marks the first time experiments have been able to distinguish changes in a material's atomic-lattice structure from the relocation of the electrons in such a blazingly fast process.

4:11 PM | L'universo come spazio limitato
Nonostante la supplenza ultraprecaria che sto portando avanti in questo periodo sia dedicata alla matematica, a volte con gli studenti si finisce a parlare di fisica, e così ecco all'improvviso spuntare fuori una discussione sull'universo finito/infinito. Spulciando tra "The meaning of relativity" di Einstein (magari presto vi spiegherò anche perché) ho trovato la seguente argomentazione sulla necessità di un universo finito:Così possiamo presentare le […]
