8:27 AM | Printed paper memory
It seems that computer memory technology is coming full circle. Pioneers in the early 19th century, such as Charles Babbage, first proposed the use of paper memory (albeit non-electronic), where a bit was stored as the presence or absence of a hole in a paper card. State-of-the-art research today again is proposing the use of paper as memory devices. This time, although he paper may be very similar, the bits are not crudely punched holes but nanofabricated device structures. In new work, […]

6:05 AM | A green method to prepare cellulose nanoparticles from waste cotton
In addition to biodegradability and the ability to be recovered and re-used, cellulose nanoparticles are light and cheap, and they have very desirable mechanical properties. Therefore, they have high potential to be used in pharmaceutics, foodstuff, cosmetics, paper production and composite manufacturing.

4:00 AM | Un ‘abbraccio cosmico’ di una famiglia di stelle
In questa nuova suggestiva immagine ottenuta dall’osservatorio dell’ESO, si possono ammirare stelle giovani disposte come in una sorta di “abbraccio cosmico” mentre sullo sfondo il panorama è dominato da nubi di gas e strisce di polvere. L’ammasso stellare, noto come NGC 3293, era probabilmente solo una nube interstellare circa dieci milioni di anni fa, ma appena […]

3:46 AM | Let’s Make This Clear
The acronym TERF—Trans-Exclusionary Radical Feminist—is not a slur, any more than “fascist” or “convicted pedophile” is. They are all plain, declarative descriptors for deplorable people. You’re free to pretend that TERF is a slur, if it feeds your inner need to feel persecuted without actually being disadvantaged. However, the rest of us do not need […]

1:58 PM | The Fermi Alternative
Given the recent Feynman explosion (timeline of events), some people may be casting about looking for an alternative source of colorful-character anecdotes in physics. Fortunately, the search doesn’t need to go all that far– if you flip back a couple of pages in the imaginary alphabetical listing of physicists, you’ll find a guy who fits…
