On June 23rd 2015, Google announced that its Google Play Music will be adding a free, ad based tier to its music streaming service. The launch of the new service creates a companion to its $9.99 a month subscription option. Analysts see this as a move to get ahead of the release of Apple Music, which is due later in the month. Google has said that it is offering the free service as a way to entice listeners to buy a subscription to the ad free version.
Some features are missing from Google's free service. Free users will be limited to six song skips per hour. Users can pause songs but there is no ability to rewind or scrub through tracks. While the paid version allows users to save playlists and listen to songs offline, the free version dose not offer that feature. Google Play's free tier is more like radio, but has at least on nice perk. All of the music that's stream is at a rate of 320kbps.
The new ad supported version of Google Play Music is similar to Songza, a company which Google purchased for what was rumored to be, the sum of $39 million, in July of 2014. The playlists are curated by music experts that also include Songza music staffers. Users can browse music by genres, mood, decade, activity, artist, song or album. Listeners will also be able to choose from themed stations such as "Driving," or "Working Out."
The new ad supported version of Google Play Music will launch first in the US. It will be available on the web on Tuesday June 30th 2015, and it should be available for iOS several days before that.

Rosetta Mision Update: Philae Lander Awakens
On June 14th 2015, the European Space Agency announced that comet lander, Philae, which landed on comet 67P/Churyumov-Gerasimenko in November of 2014, had finally awaken from its hibernation. Philae went into hibernation after landing in the shadow of a cliff, which prevented it from receiving enough sunlight to recharge its solar batteries. Philae sent back data for 57 hours before it ran out of power.
Stephen Ulamec, Philae's project manager, stated that, "the lander is doing well, operating at a temperature of -35 degrees Celsius and a power of 24 watts." The lander has already analyzed 300 of its more than 8,000 data packets. In the coming days, scientist hope to access those data packets in an effort to determine where Philae actually landed.
Scientists are set to change the orbit of the Rosetta spacecraft, which has been orbiting comet 67P/Churyumov-Gerasimenko. Their goal is to bring the orbiter within 180 kilometers of the comet's surface, in order to give the Rosetta spacecraft stronger and longer communication links with the Philae lander. The Rosetta spacecraft can only receive a signal from Philae while the lander is in direct sunlight, and in a direct line of sight.
Philae's mission is to study whether comets may have contributed to life on Earth. It is equipped with a small drill and two mass spectrometers that are designed to analyze the chemical composition of the comet's soil. Scientist are hoping that the comet's proximity to the sun will provide Philae with enough energy to carry out its objective.

A Rat's Limb Is Grown In The Lab
On June 3rd 2015, researchers at Massachusetts General Hospital announced that they had successfully grown a rat's limb in the laboratory. The limb is a functioning artificial leg that not only responds to stimuli, but also circulates blood. Dr. Harald Ott, one of the researchers, believes that this is the first step in the creation of made to order body parts for humans.
To create the new rat limb, Dr Ott and his team used a process called decellularization. In this process, the limb of a dead rat is stripped of any living cells to expose the "scaffolds," or non living parts. The limb is then recellularized by planting the cells that make up the muscles and blood vessels onto the "scaffolds". The materials were then placed in a bioreactor and allowed to grow for two weeks.
After two weeks the researchers grafted some skin on to the leg, which had no bone or cartilage. Next, the rat limb was attached to a living rat. It was found that the living rat was able to circulate its blood through the biolimb. A test of an unattached biolimb revealed that the muscles moved normally. With electrical stimulation, the rat limb's paw clenched and unclenched with 80% of the strength of a newborn animal.
Dr Ott and his team believe that this process can also be used to grow biolimbs for humans. The technique of using a recipient's own genetic material has already been used to build synthetic human bladders, windpipes, and other organs. These organs, however, are simple in comparison to limbs, which contain nerves, muscles, and blood vessels, and are required to perform in a complex manner.
If biolimbs for humans comes to fruition, they will look, and respond like the real thing. And, because they will be made from the recipients own cells, the chances of rejection are unlikely.

An Antarctic Ice Shelf Is Melting
On May 15th 2015, NASA released a new study that revealed that one of Antarctica's ice shelves, Larsen B, is melting and facing collapse by 2020. A team of scientists led by Ala Khazendar has found that the Larsen B ice shelf is flowing faster, becoming increasingly more fragmented, and there are large cracks developing. The Larsen B ice shelf suffered a partial collapse in 2002. At that time the shelf lost a region larger than Rhode Island, while leaving 618 square miles of it left.
Ice shelves are important because they are the gatekeepers that keep glaciers from flowing into the ocean from Antarctica. Khazendar said that these changes are a warning and that, "Although it is fascinating scientifically to have a front row seat to watch the ice shelf becoming unstable and breaking up, it's bad news for our planet." Increasing glacial ice can and will contribute to the rise in sea levels around the world.
Khazendar's team ran a multiyear airborne survey campaign that provided them with unprecedented documentation of Antarctica's glaciers, ice shelves, and ice sheets. Data was gathered on surface ice elevations and bedrock depths by using instrumented aircraft that participated in NASA's Operation Icebridge. Khazendar said that, " Change has been relentless."
The west coast of the Antarctica Peninsula is one of the fastest warming places on Earth, with an average annual temperature increase of 2.5 degree Celsius in the last five years. A NASA release on the study stated, "After the 2002 Larsen B collapse, the glacier behind the collapsed part of the shelf accelerated as much as eightfold - comparable to a car accelerating from 55 to 440 miles per hour.

The Thrill Is Gone, As BB King Dies At 89
BB King passed away quietly in his sleep on May 14th 2015. He was 89 years old. Mr King had been suffering from acute symptoms of type 2 diabetes that led to several strokes. Mr king had continued to perform despite being in hospice care for his failing health. He stopped touring in October 2014 after suffering from dehydration and exhaustion.
He was born Riley B King on September 16th 1925, in Itta Bena, Mississippi. As the son of a sharecropper, he picked cotton in his youth. Growing up, his dream was to become a Gospel singer and learned guitar from his pastor. As a teen, he made the decision to hitchhike to Memphis where he played music on the street.
After playing for a year, he was asked to play on Sonny Boy Williamson's radio program. After playing at local night spots, Mr King became a DJ at the black owned radio station in Memphis, WDIA. It was there that he earned the nickname, Beale Street Blues Boy, which was later shortened to Blues Boy.
He made his first recording in 1949 and went on to have a string of Blues hits while signed to a long term contract with Kent/RPM/Modern, including, "Three O'Clock Blues." That song reached number one on the R&B charts and became his first national hit. In 1951, on the strength of that number one hit, Mr King went on his first national tour. It was while he was in New York that he shortened his name to BB.
While he remained popular with black audiences in the 50's, it wasn't until the mid sixties, that things began to change. A new group of young rock artists, which included George Harrison, Eric Clapton, and Jimi Hendrix, began to attribute their playing styles to Mr King's influence. In fact, Mr King once noted that it was his performance at the Filmore West in San Fransisco, that opened the doors to his commercial success.
In 1969, he released what became his biggest hit, "The Thrill Is Gone." From there he went on to tour around the world, doing 300 or more shows a year. Over the course of his career he won 18 Grammy Awards, the Presidential Medal of the Arts, and the Kennedy Center Honors. In 2000, he released the double platinum, "Riding With The King," recorded with Eric Clapton.
Mr King is survived by 11 children. After a memorial service in Las Vegas on May 23rd, Mr King's body will be taken to Memphis on May 27th, for a procession down Beale St to Handy Park. Public viewing will take place on May 29th at the BB King Museum in Indianola, Mississippi. His funeral will take place on May 30th at the Bell Grove M.B. Church, also in Indianola.

Legal Problems Lead To Grooveshark Shut Down
On April 30th 2015, Escape Media, parent company to Grooveshark, announced that it was shutting down the music streaming site immediately. Grooveshark, which first launched in 2006, and which had been sued for copyright infringement by the recording industry for many years, entered into a settlement with Universal Music group, Sony Music Entertainment, and Warner Music Group.
Under the terms of the settlement, Grooveshark agreed to wipe its servers clean of all of the record companies' music, surrender ownership of its website, mobile apps, patents and intellectual property. The settlement was reached after a judge ruled that infringement damages could reach as much as $150,000 a song, with as many as 4,907 tracks as part of the lawsuit.
The RIAA, (Recording Industry Assciation of America) stated that, "This is a very important victory for artists and for the entire music industry. This settlement ends a major source of infringing activity." In court papers, the plaintiffs described Grooveshark as, "the linear descendant," of file sharing services such as Napster, Grokster, and Limeware, all of which were shut down due to copyright infringement.
Grooveshark's founders, Josh Greenburg and Sam Tarantino posted a statement on the site's home page that stated that they admit to making mistakes in their efforts to give music fans "the experience that they felt was missing from the web." They apologized both to the record companies for infringing and to their users for letting them down. They also urged their users, whose numbers had reached as many as 35 million, to use other licensed sites such as Spotify, Google Play, Beats, Rhapsody, Dezzer, and Rdio.
