Gravitational Anomalies of Mercury


What's that under the surface of Mercury? The robotic MESSENGER spacecraft that had been orbiting planet Mercury for the past four years had been transmitting its data back to Earth with radio waves of very precise energy. The planet's gravity, however, slightly changed this energy when measured on Earth, which enabled the reconstruction of a gravity map of unprecedented precision. Here gravitational anomalies are shown in false-color, superposed on an image of the planet's cratered surface. Red hues indicate areas of slightly higher gravity, which in turn indicates areas that must have unusually dense matter under the surface. The central area is Caloris Basin, a huge impact feature measuring about 1,500 kilometers across. Last week, after completing its mission and running low on fuel, MESSENGER was purposely crashed onto Mercury's surface.

How to stop songs from getting stuck in our heads? Chew some gum!

An effective solution to get rid of earworms, those annoying tunes that keep on re-playing in never ending loops in our heads, has been found by a team of scientists at the University of Reading, UK. Published in the Quarterly Journal of Experimental Psychology (Taylor & Francis) the results of the research show the best way to block obsessive melodies is neither to read a good novel nor solve complex anagrams but, simply, to chew gum.

As much widespread as frustrating, earworms are experienced by over 99% of individuals (J. Kellaris) and often source of great stress for many. The part of our brain that processes auditory information – the auditory cortex – is triggered when we listen to a song so, when we hear a familiar tune again, our mind fills in the rest, repeatedly. This would suggest tune wedgies “may be a form of involuntary musical memory” explains Dr Philip Beaman, the academic leading the research. Getting rid of earworms is tricky but the academic believes the solution is to be found in gum; the act of gum-chewing is very similar to irrelevant sub-vocalisation, which has proved to degrade short term memory performance as well as auditory images.

Not only “auditory images [are] less vivid when [individuals are] engaged in tasks” loading on their inner voice, but irrelevant sub-vocalisation, like chewing, reduces the repetition of sticky tunes, explains Beaman. To test this theory the team carried out three separate experiments, in which participants were exposed to catchy tunes while either chewing or not chewing gum. Experiment 1 evaluated the effect of bubble-gum on the conscious appearance of musical images, as well as the recurrence of earworms once attempts to suppress them had ceased; participants exposed to a popular melody were first asked not to think about the music, and then let free to do so. Predictably, results proved gum-chewing reduced the number of times the tune was consciously experienced in both music suppression and overt expression condition. Experiment 2, which looked at the actual ‘hearing’ of music in participants’ heads, also demonstrated the reducing effect of gum-chewing upon the music-hearing phenomenon. Last but not the least, Experiment 3 was designed to assess whether the effects of gum were common to any kind of motor activity, or specific to the speech articulators only; to this end, partakers were asked to either chew some gum or tap with their fingers at the beat of a novel melody. Interestingly, the outcome showed that motor activity per se (tapping) was less effective than sub-vocal actions (chewing) in moderating the appearance of earworms.

The first to look at gum in the context of voluntary as well as involuntary musical imagery, this study demonstrates chewing gum interferes with the experience of hearing musical recollections therefore can be recommended as an aid to get rid of earworms. So, next time we get stuck with a tune, let’s forget intricate anagrams and get some bubble-gum instead.

What Did Charles Darwin Think Of Religion?

In 1859, the English amateur naturalist Charles Darwin published his seminal work, On the Origin of Species, or, to give its full title, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. He summarized his theory of natural selection with: “As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected. From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form.” Darwin never mentions God’s hand in his theory…

NYC Stores Sell Alcohol to Minors

All New Yorkers can play a role in preventing youth access to alcohol.

In 2014, more than half of stores throughout NYC sold alcohol to underage buyers. It’s not just the corner store either – liquor stores were as likely to sell to underage decoys as grocers or pharmacies, according to the NY State Liquor Authority.

Stores have a responsibility to keep alcohol out of the hands of minors. In 2011, there were nearly 7,000 alcohol-related emergency department visits among New Yorkers under age 21, and one in four NYC adolescents have consumed alcohol in the past 30 days.

Anyone who sees or suspects a store of selling alcohol to people under 21 should call 311.

nprbooks: In 1887, American journalist Nellie Bly had herself...



nprbooks:

In 1887, American journalist Nellie Bly had herself committed to New York’s notorious Blackwell’s Island insane asylum – on purpose, as part of an assignment from the New York World newspaper. When she was released 10 days later, she had seen cruelty that made her shudder. In her account for the World, she wrote:

“I left the insane ward with pleasure and regret. Pleasure that I was once more able to enjoy the free breath of heaven; regret that I could not have brought with me some of the unfortunate women who lived and suffered with me, and who I am convinced are just as sane as I was and am now myself.”

The story that resulted is called “Ten Days in a Mad-House,” and it’s one of many pieces collected in a new volume, Nellie Bly: Around the World in Seventy-Two Days and Other Writings — released this year in honor of Bly’s 150th birthday. The book’s editor, Jean Lutes, talked about Bly’s legacy on Morning Edition yesterday.

Trajectory of Alan Shepard's Historic Flight


Fifty-four years ago on May 5, 1961 only 23 day after Yuri Gagarin of the then-Soviet Union became the first person in space, NASA astronaut Alan Shepard launched at 9:34 a.m. EDT aboard his Freedom 7 capsule powered by a Redstone booster to become the first American in space. His historic flight lasted 15 minutes, 28 seconds.

Funeral of Bobby Sands

May 5th 1981: Bobby Sands dies

On this day in 1981, the Irish republican activist Bobby Sands died in a Northern Ireland jail after a hunger strike. Sands, born in Belfast in 1954, joined the Republican Movement aged eighteen, and faced intimidation from loyalists in his community. He was a militant member of the movement during the Irish Troubles, and spent three years in prison for possessing firearms. In 1976, Sands was again arrested in connection to the bombing of a furniture company, and whilst the charges were flimsy and the evidence slim, Sands was sentenced to fourteen years in prison. It was while he was in prison that Sands became a famous figure in Ireland and in Britain, for his defiance of the prison system and confrontation of authorities. On March 1st 1981, Sands led nine other Provisional IRA prisoners - who considered themselves prisoners of war - on a hunger strike, demanding prison reforms like the right to wear their own clothes, and right to refuse prison work. Sands refused to end his strike until they gave into his requests, and during the first seventeen days of the strike lost sixteen pounds. His actions made him a nationalist hero and, while he was still on hunger strike, Sands was elected as a Sinn Fein Member of Parliament for Fermanagh and South Tyrone. Sands’s health rapidly deteriorated, and just a few days after slipping into a coma, he died on May 5th 1981 aged twenty-seven; Bobby Sands had refused to eat for sixty-six days. He was not the last to die from hunger strike, and several other nationalists also died in similar conditions. His death prompted widespread rioting and over 100,000 people attended his funeral. While a controversial figure, Sands remains a hero to many Irish republicans, and his stoic determination has inspired countless political dissidents around the world.

“They have nothing in their whole imperial arsenal that can break the spirit of one Irishman who doesn’t want to be broken“
