Choline is one of the newest nutrients to be
added to the list of human vitamins. It
was only added to the list of required nutrients by the National Academy of
Sciences (NAS) in 1998. While the NAS
does not officially recognize choline as a vitamin specifically belonging to
the B-complex family of vitamins, it is officially recognized as a required
nutrient that you need in your everyday meal plan. Shrimp, scallops and eggs are rich in
choline.

Does the Hubble telescope show us what the
universe really looks like? Yes and
no, according to NASA. When Hubble beams
down images, astronomers have to make many adjustments, such as adding color
and patching multiple photos together, to that raw data before the space
observatory's images are released to the public. These photos are an enhanced
version, since most celestial objects, such as nebulas, emit colors that are
too faint for human eyes to make out. It
takes a telescope, letting light build up in its CCD over time, to see the rich
hues in Hubble photos. And for other
Hubble images, scientists assign colors to the filters that don't correspond to
what that light would look like to human eyes.
They do this when using light from infrared and ultraviolet filters,
since those wavelength ranges have no natural colors, or when combining light
from slightly different shades of the same color. "Creating color images out of the
original black-and-white exposures is equal parts art and science," NASA
said. For example, Hubble photographed
the Cat's Eye Nebula through three narrow wavelengths of red light that correspond
to radiation from hydrogen atoms, oxygen atoms, and nitrogen ions (nitrogen
atoms with one electron removed). In
that case, they assigned red, blue and green colors to the filters and combined
them to highlight the subtle differences.
In real life, those wavelengths of light would be hard to distinguish
for humans. The Hubble Space Telescope
launched in April 1990 and has been visited by NASA astronauts multiple times
for vital repairs, maintenance and upgrades.

John Hoyer Updike (1932–2009) was an American novelist, poet, short story writer, art critic, and literary critic. Updike's most famous work is his
"Rabbit" series (the novels Rabbit, Run; Rabbit Redux; Rabbit Is Rich; Rabbit at Rest; and the novella Rabbit Remembered), which chronicles the
life of the middle-class everyman Harry "Rabbit" Angstrom over
the course of several decades, from young adulthood to death. Both Rabbit Is Rich (1982)
and Rabbit
at Rest (1990)
were recognized with the Pulitzer Prize. Updike is one of only three authors (the
others were Booth Tarkington and William Faulkner) to win the Pulitzer Prize
for Fiction more than once. He published
more than twenty novels and more than a dozen short story collections, as well
as poetry, art criticism, literary criticism and
children's books. Updike's highly
distinctive prose style features a rich, unusual, sometimes arcane vocabulary
as conveyed through the eyes of "a wry, intelligent authorial voice"
that extravagantly describes the physical world, while remaining squarely in
the realist tradition. He
described his style as an attempt "to give the mundane its beautiful
due." Updike was born in Reading, Pennsylvania,
the only child of Linda Grace (née Hoyer) and Wesley Russell Updike, and was
raised in the nearby small town of Shillington.
His mother's attempts to become a
published writer impressed the young Updike. "One of my earliest memories", he
later recalled, "is of seeing her at her desk... I admired the writer's
equipment, the typewriter eraser, the boxes of clean paper. And I remember the brown envelopes that
stories would go off in—and come back in."
These early years in Berks County, Pennsylvania, would influence the environment
of the Rabbit Angstrom tetralogy, as well as
many of his early novels and short stories. Updike graduated from Shillington High
School as
co-valedictorian and
class president in 1950 and attended Harvard with a full scholarship. At Harvard, he soon became well known among
his classmates as a talented and prolific contributor to the Harvard Lampoon, of which he served as
president. He graduated summa cum laude in
1954 with a degree in English. Upon graduation, Updike attended The
Ruskin School of Drawing and Fine Art at
the University of Oxford with
the ambition of becoming a cartoonist.
After returning to the United States, Updike and his family moved to New
York, where he became a regular contributor to The New Yorker. This was the beginning of his professional
writing career. Find cultural references and bibliography at http://en.wikipedia.org/wiki/John_Updike
Twenty-five of the top robotics
organizations in the
world will gather to compete for $3.5 million in prizes as they attempt a
simulated disaster-response course. The
event is free to attend and open to the public.
It takes place June 5-6, 2015 at Fairplex (home of the LA County Fair)
in Pomona, California, just east of downtown Los Angeles. The DARPA Robotics
Challenge (DRC) is a competition of robot systems and software
teams vying to develop robots capable of assisting humans in responding to
natural and man-made disasters.
Participating teams, representing some of the most advanced robotics
research and development organizations in the world, are collaborating and
innovating on a very short timeline to develop the hardware, software, sensors,
and human-machine control interfaces that will enable their robots to complete
a series of challenge tasks selected by DARPA for their relevance to disaster
response. The DRC Finals will require
robots to attempt a circuit of consecutive physical tasks, with degraded
communications between the robots and their operators; the winning team will
receive a $2 million grand prize; DARPA plans to award $1 million to the
runner-up and $500,000 to the third-place team.

In 1973, the U.S. Defense Advanced
Research Projects Agency (DARPA) initiated a research
program to investigate techniques and technologies for interlinking packet
networks of various kinds. The objective
was to develop communication protocols which would allow networked computers to
communicate transparently across multiple, linked packet networks. This was called the Internetting project and
the system of networks which emerged from the research was known as the
"Internet." The system of
protocols which was developed over the course of this research effort became
known as the TCP/IP Protocol Suite, after the two initial protocols
developed: Transmission Control Protocol
(TCP) and Internet Protocol (IP). http://www.internetsociety.org/internet/what-internet/history-internet/brief-history-internet-related-networks

CLEAN WATER RULE About 117 million Americans--one in
three people--get drinking water from streams that lacked clear protection
before the Clean Water Rule. In
developing the rule, the agencies held more than 400 meetings with stakeholders
across the country, reviewed over one million public comments, and listened
carefully to perspectives from all sides.
EPA and the Army also utilized the latest science, including a report
summarizing more than 1,200 peer-reviewed, published scientific studies which
showed that small streams and wetlands play an integral role in the health of
larger downstream water bodies. The
Clean Water Rule will be effective 60 days after publication in the Federal
Register.

Quotes about the same book No
two persons ever read the same book.
Edmund Wilson, U.S. literary critic (1875-1972) You can never step
into the same book twice, because you are different each time you read it. John Barton
Canadian poet (b. 1957)
"Cats don't have friends. They have co-conspirators."

Colony. On this date in 1653, Georg Muffat, French organist and composer was
born.
