Gravitational bending of light reveals exoplanets with large orbital radii.
"Most of the more than 600 exoplanets discovered to date have been found through Doppler evidence of periodic host-star motion or photometric evidence of transits across a star’s face. Both methods are strongly biased in favor of planets with orbital radii much smaller than Earth’s, which defines 1 astronomical unit (AU). Gravitational microlensing is an alternative technique that’s most sensitive to planets a few AU from their stars. It favors very distant stars and it’s relatively unbiased as to stellar mass. Though microlensing’s discovery rate is still modest, it appeals to those who seek a representative galactic survey of planets with orbits like those of the solar system." http://www.physicstoday.org/resource/1/phtoad/v65/i3/p19_s1

Isaac Newton and the Philosopher's Stone
From http://en.wikipedia.org/wiki/Isaac_Newton's_occult_studies
"Of the material sold during the 1936 Sotheby's auction, several documents indicate an interest by Newton in the procurement or development of The Philosopher's Stone. Most notably are documents entitled, "Artephius his secret Book", ... "The Epistle of Iohn Pontanus"..... , these are themselves a collection of excerpts from another work entitled, "Nicholas Flammel, His Exposition of the Hieroglyphicall Figures which he caused to be painted upon an Arch in St Innocents Church-yard in Paris. Together with The secret Booke of Artephius, And the Epistle of Iohn Pontanus: Containing both the Theoricke and the Practicke of the Philosophers Stone". ... Nicolas Flamel, (one subject of the aforementioned work) was a notable, though mysterious figure, often associated with the discovery of The Philosopher's Stone, Hieroglyphical Figures, early forms of tarot, and occultism. Artephius, and his "secret book", were also subjects of interest to 17th century alchemists."
As told in the previous post, Isaac Newton became the Master of the Mint. In the case that he had actually discovered the Philosopher's Stone.

Master of the Mint
I read today that Sir Isaac Newton was a "Master of the Mint." It is quite interesting this activity of the great scientist. But, what is the Mint? It is the "place where money is coined." The term derived from a Latin moneta, that we have, as it is, in Italian.

The online etymology dictionary tells that the adjective meaning "perfect" (like a freshly minted coin) is from 1902; hence "mint condition". I like this coin as a fresh mint candy.

Graphyne
"Super-strong, highly conducting graphene is the hottest ticket in physics, but new computer simulations suggest that materials called graphynes could be just as impressive."

Uturuncu
"Uturuncu, or Uturunku, the highest summit in southwestern Bolivia, is a stratovolcano. ...Researchers have determined that a large, roughly circular "disc" of land surrounding the volcano, approximately 70 km across, has been rising at a rate of 1 to 2 cm per year since at least the early 1990s, making it "one of the fastest uplifting volcanic areas on the Earth"." http://en.wikipedia.org/wiki/Uturuncu
