11:00 AM | Fear Mongering in the NYT: Does Wearable Tech Cause Cancer?
tl;dr: There is zero direct evidence that wearable tech causes cancer. The indirect evidence ain’t too good, either. I suppose it’s a natural human reaction to worry a bit when some new technology is announced. Will it hurt privacy rights? How will it affect the way people interact? Will it give people cancer? Of course, that last one will give you a frisson of fear, an unconscious and reflexive chill that bites the back of your brain before a more rational reaction can kick in. The […]

8:00 AM | G is for Goddamned Goshawk
I knew something was wrong the moment I opened the orchard gate. My guinea fowl were squawking like crazy, buckwheat!, buckwheat!, and none of my two dozen or so chickens were anywhere in sight. I scanned the area near around poultry barn for signs of a predator, but saw nothing. Until I reached the chicken […]

4:00 AM | ATLAS e CMS sul valore della massa di Higgs
Alla 50° conferenza “Rencontres de Moriond” di La Thuile, in Italia, i fisici degli esperimenti ATLAS e CMS hanno presentato per la prima volta i risultati congiunti sul valore della massa del bosone di Higgs. I dati indicano un valore di mH = 125.09 ± 0.24 (0.21 errore statistico ± 0.11 errore sistematico) GeV, che corrisponde ad una … Continue reading ATLAS e CMS sul valore della massa di Higgs →

9:43 PM | Are the first stars in the Universe invisible? (Synopsis)
“Dwell on the beauty of life. Watch the stars, and see yourself running with them.” -Marcus Aurelius Let there be light! You’d think that would be enough: that you form stars in the Universe, you see those stars in the Universe, and that tells you about what’s out there. If only it were that simple.…

6:55 PM | A Possible Detection of Dark Matter in a Dwarf Galaxy!
If dark matter particles can collide to release gamma-rays, the best place to see them will be in the centers of dwarf galaxies. Archival Fermi-LAT images around Reticulum 2 show the first ever detection of gamma-rays from a dwarf galaxy. Dark matter detection may be close at hand!

11:15 AM | Orion: Going Deep
One of the most globally recognizable constellations in the sky is, undoubtedly, Orion. Straddling the equator of the sky, it can be seen from literally every point on Earth, and its resemblance to a human standing upright spans cultures. It’s a landmark (skymark?) in the early months of the year, up high at sunset, and a favorite among astronomers. I’ve looked at it hundreds of times. Thousands. I've used my eyes, I’ve used binoculars, I’ve used a series of telescopes […]

4:00 AM | COMPASS dimostra la ‘rigidità’ dei pioni
In un articolo apparso su Physical Review Letters, i fisici che lavorano all’esperimento COMPASS del CERN riportano una misura di fondamentale importanza relativa all’interazione forte. L’interazione forte lega i quark nei protoni e neutroni e, quindi, i protoni e i neutroni all’interno dei nuclei atomici di tutti gli elementi di cui è costituita la materia. All’interno … Continue reading COMPASS dimostra la ‘rigidità’ dei […]
