"Engineers have designed a device that harvests energy from the reverberation of heartbeats through the chest and converts it to electricity to run a pacemaker or an implanted defibrillator.
According to a statement, these medical machines — developed at Michigan University — send electrical signals to the heart to keep it beating in a healthy rhythm.
By taking the place of the batteries that power them today, the new energy harvester could save patients from repeated surgeries."

Why the Ocean is Blue?

"Why is the ocean blue? Speculation about the blue color of the ocean, as seen from above, goes way back. Lord Rayleigh claimed it was simply reflection of the blue sky. The correct explanation required combining the 19th-century ideas of Robert Bunsen, who felt that the color depended on light absorption by water, and Jacques-Louis Soret, who felt that the color was entirely due to scattering. C. V. Raman pointed out the importance of molecular scattering, and in 1923 Vasily Shuleikin combined those ideas to develop a complete explanation of the color of the sea."

More Planets than Stars

Microlensing suggests that our galaxy has more planets than stars, buBertram M. Schwarzschild

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.
http://www.etymonline.com/index.php?term=mint
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

Flying pyramids

Intrinsic Stability of a Body Hovering in an Oscillating Airflow

Bin Liu, Leif Ristroph, Annie Weathers, Stephen Childress, and Jun Zhang

Phys. Rev. Lett. 108, 068103 (2012)

Published February 9, 2012

Synopsis: Floats Like a Pyramid, Physics, APS

"Writing in Physical Review Letters, Bin Liu and co-workers at New York University present results from experiments on an inanimate pyramid-shaped flyer, or “bug.” Their choice of the shape was made in view of previous experiments with tethered flight, which showed that pyramids could hover in an airflow."
