Classic Chords #6 – The Beatles – A Hard Day’s Night

Perhaps the chord that is the most distinctive and yet the most difficult to pin down as a solo player is the opening thrash of The Beatles’ “A Hard Day’s Night”. Everybody who picks up a guitar tries to get that chord, whether classical player, rock guitarist, 12-string player, whatever. Now, I figured it was some kind of Gm11 but with something extra going on. Or perhaps an F/G but with an extra note here or there. First off, I think George Harrison is on record as sayi...

 
Short-Snouted Sea Monsters Evolved Rapidly After Wipeout

The discovery of a short-snouted, oceangoing reptile with a whip-like tail suggests that some marine reptiles evolved quickly (geologically speaking) after a mass extinction 250 million years ago, a new study finds. The finding turns an old theory on its head, showing that early marine reptiles didn't evolve slowly after the end-Permian extinction. The extinction wiped out about 96 percent of all marine species, largely due to climate change, volcanic eruptions and rising sea levels, the researc...

 
Classic Chords #5 – Rush Limelight

As I mentioned, in Classic Chord #1 in my early teens I was chasing the dream of being the next Alex Lifeson, picking out the pseudo-classical intros to songs like “Panacea”, “A Farewell to Kings” and “The Trees”, later “Broon’s Bane” from Exit…stage left and rocking out (on a nylon string guitar!) to “Working Man”, “Bastille Day” and “Circumstances”. One recurring theme in Lifeson’s playing is...

 
Later, Gator: 'Monster' Nile Crocodiles May Be Invading Florida

Florida's native alligators and crocodiles could be facing some new competition — from a bigger and meaner member of their own crocodilian family. Nile crocodiles — American crocodiles' larger, more aggressive cousins from the African continent — have been identified in the wild in southern Florida for the first time, according to a new study. The scientists caught three young crocodiles — one of which was captured on the porch of a Miami home — and, through genetic...

Mars closest to Earth

You’ll have to hope for clears skies tonight as Mars will be the closest to Earth it has been since November 2005. That said, it will not appear to be any more than a rather bright ruddy point in the sky unless you’re viewing it with a decent telescope. It will be a mere 75.3 million kilometres away. As EarthSky explains, the point of clostest proximity is not when lie directly between the Sun and Mars, because plenatary orbits are not circular they are elliptical and those orbits ar...

Hormone treatment in transgender persons could shed light on role of sex hormones in bone density

Male-to-female (MtF) transgender persons have a greater increase in bone mineral density than female-to-male (FtM) persons in their first year of hormone treatment. The research helps scientists further understand the roles sex hormones play on bone development and maintenance in both sexes....

[Research Article] Topoisomerase 1 inhibition suppresses inflammatory genes and protects from death by inflammation

The host innate immune response is the first line of defense against pathogens and is orchestrated by the concerted expression of genes induced by microbial stimuli. Deregulated expression of these genes is linked to the initiation and progression of diseases associated with exacerbated inflammation. We identified topoisomerase 1 (Top1) as a positive regulator of RNA polymerase II transcriptional activity at pathogen-induced genes. Depletion or chemical inhibition of Top1 suppresses the host res...
