Dr. Jerald Block is a psychiatrist based in Portland, Oregon, United States. Dr. Block has attracted some media attention due to one theory of his – the idea that Internet addiction can be viewed as a distinct mental condition.

In an interview with Wikinews, Dr. Block discusses this theory, including what needs to be done about it, and the alleged violent response that can arise from an addict’s withdrawal. Below is the full exclusive interview.

NASA has said that preliminary investigations show that Discovery is safe to fly home.

Final findings will not be available for several days as a team of 200 experts study all video and stills footage taken of the shuttle during launch, and on approach to the International Space Station (ISS), with which Discovery docked earlier today.

Images from new cameras have revealed that a section of foam weighing some 250 g fell away from the external fuel tank during launch, but did not strike the Orbiter. However, NASA has announced the grounding of all further planned Shuttle launches until they have a firm understanding of why the foam comes away, and what to do about it.

A piece of foam striking the Columbia‘s wing during take-off in January 2003 was responsible for the loss of the craft as it made its reentry to Earth’s atmosphere.

As part of the check for damage the crew of Discovery used a laser-scanner on the robotic arm to inspect the craft’s wing leading-edges and nosecone. The belly of the Orbiter will be checked later this week.

In a first, the Shuttle also performed a slow back-flip in some 180 m from the ISS enabling the two-man crew of the space station to take high-resolution images of the underside of the Orbiter.

Over the past week, diplomatic actions have averted — or, at least delayed — military strikes on Syria by the United States. Wikinews sought input from a range of international experts on the situation; and, the tensions caused by Russia’s support for the al-Assad regime despite its apparent use of chemical weapons.

Tensions in the country increased dramatically, late August when it was reported between 100 and 1,300 people were killed in an alleged chemical attack. Many of those killed appeared to be children, with some of the pictures and video coming out of the country showing — according to witnesses — those who died from apparent suffocation; some foaming at the mouth, others having convulsions.

Amongst Syria’s few remaining allies, Iran, China, and Russia continue to oppose calls for military intervention. In an effort to provide a better-understanding of the reasoning behind their ongoing support, the following people were posed a range of questions.

Evansville, Indiana, United States — This past week marked the opening night of an Andy Warhol exhibit at the University of Southern Indiana. USI’s art gallery, like 189 other educational galleries and museums around the country, is a recipient of a major Warhol donor program, and this program is cultivating new interest in Warhol’s photographic legacy. Wikinews reporters attended the opening and spoke to donors, exhibit organizers and patrons.

The USI art gallery celebrated the Thursday opening with its display of Warhol’s Polaroids, gelatin silver prints and several colored screen prints. USI’s exhibit, which is located in Evansville, Indiana, is to run from January 23 through March 9.

The McCutchan Art Center/Pace Galleries at USI bases its exhibit around roughly 100 Polaroids selected from its collection. The Polaroids were all donated by the Andy Warhol Photographic Legacy Program, according to Kristen Wilkins, assistant professor of photography and curator of the exhibit. The Andy Warhol Foundation for the Visual Arts made two donations to USI Art Collections, in 2007 and a second recently.

Kathryn Waters, director of the gallery, expressed interest in further donations from the foundation in the future.

Since 2007 the Andy Warhol Photographic Legacy Program has seeded university art galleries throughout the United States with over 28,000 Andy Warhol photographs and other artifacts. The program takes a decentralized approach to Warhol’s photography collection and encourages university art galleries to regularly disseminate and educate audiences about Warhol’s artistic vision, especially in the area of photography.

Wikinews provides additional video, audio and photographs so our readers may learn more.

Wilkins observed that the 2007 starting date of the donation program, which is part of the Andy Warhol Foundation for the Visual Arts, coincided with the 20th anniversary of Andy Warhol’s death in 1987. USI was not alone in receiving a donation.

K.C. Maurer, chief financial officer and treasurer at the Andy Warhol Foundation, said 500 institutions received the initial invitation and currently 190 universities have accepted one or more donations. Institutional recipients, said Mauer, are required to exhibit their donated Warhol photographs every ten years as one stipulation.

While USI is holding its exhibit, there are also Warhol Polaroid exhibits at the Tang Teaching Museum and Art Gallery at Skidmore College in Saratoga Springs, New York and an Edward Steichen and Andy Warhol exhibit at the Mary & Leigh Block Museum of Art at Northwestern University in Evanston, Illinois. All have received Polaroids from the foundation.

University exhibits can reach out and attract large audiences. For example, the Weatherspoon Art Museum at the University of North Carolina at Greensboro saw attendance levels reach 11,000 visitors when it exhibited its Warhol collection in 2010, according to curator Elaine Gustafon. That exhibit was part of a collaboration combining the collections from Duke University, located in Durham, North Carolina, and University of North Carolina at Chapel Hill, which also were recipients of donated items from the Andy Warhol Photographic Legacy Program.

Each collection donated by the Andy Warhol Photographic Legacy Program holds Polaroids of well-known celebrities. The successful UNC Greensboro exhibit included Polaroids of author Truman Capote and singer-songwriter Carly Simon.

“I think America’s obsession with celebrity culture is as strong today as it was when Warhol was living”, said Gustafon. “People are still intrigued by how stars live, dress and socialize, since it is so different from most people’s every day lives.”

Wilkins explained Warhol’s obsession with celebrities began when he first collected head shots as a kid and continued as a passion throughout his life. “He’s hanging out with the celebrities, and has kind of become the same sort of celebrity he was interested in documenting earlier in his career”, Wilkins said.

The exhibit at USI includes Polaroids of actor Dennis Hopper; musician Nick Rhodes of Duran Duran; publishers Jann Wenner of Rolling Stone Magazine and Carlo De Benedetti of Italy’s la Repubblica; disco club owner Steve Rubell of Studio 54; photographers Nat Finkelstein, Christopher Makos and Felice Quinto; and athletes Vitas Gerulaitis (tennis) and Jack Nicklaus (golf).

Wikinews observed the USI exhibit identifies and features Polaroids of fashion designer Halston, a former resident of Evansville.

University collections across the United States also include Polaroids of “unknowns” who have not yet had their fifteen minutes of fame. Cynthia Thompson, curator and director of exhibits at the University of Arkansas, Fayetteville, said, “These images serve as documentation of people in his every day life and art — one which many of us enjoy a glimpse into.”

Warhol was close to important touchstones of the 1960s, including art, music, consumer culture, fashion, and celebrity worship, which were all buzzwords and images Wikinews observed at USI’s opening exhibit.

He was also an influential figure in the pop art movement. “Pop art was about what popular American culture really thought was important”, Kathryn Waters said. “That’s why he did the Campbell Soup cans or the Marilyn pictures, these iconic products of American culture whether they be in film, video or actually products we consumed. So even back in the sixties, he was very aware of this part of our culture. Which as we all know in 2014, has only increased probably a thousand fold.”

“I think everybody knows Andy Warhol’s name, even non-art people, that’s a name they might know because he was such a personality”, Water said.

Hilary Braysmith, USI associate professor of art history, said, “I think his photography is equally influential as his graphic works, his more famous pictures of Marilyn. In terms of the evolution of photography and experimentation, like painting on them or the celebrity fascination, I think he was really ground-breaking in that regard.”

The Polaroid format is not what made Warhol famous, however, he is in the company of other well-known photographers who used the camera, such as Ansel Adams, Chuck Close, Walker Evans, Robert Mapplethorpe, and Helmut Newton.

Wilkins said, “[Warhol] liked the way photo booths and the Polaroid’s front flash looked”. She explained how Warhol’s adoption of the Polaroid camera revealed his process. According to Wilkins, Warhol was able to reproduce the Polaroid photograph and create an enlargement of it, which he then could use to commit the image to the silk screen medium by applying paint or manipulating them further. One of the silk screens exhibited at USI this time was the Annie Oakley screen print called “Cowboys and Indians” from 1987.

Wilkins also said Warhol was both an artist and a businessperson. “As a way to commercialize his work, he would make a blue Marilyn and a pink Marilyn and a yellow Marilyn, and then you could pick your favorite color and buy that. It was a very practical salesman approach to his work. He was very prolific but very business minded about that.”

“He wanted to be rich and famous and he made lots of choices to go that way”, Wilkins said.

Kiara Perkins, a second year USI art major, admitted she was willing to skip class Thursday night to attend the opening exhibit but then circumstances allowed for her to attend the exhibit. Why did she so badly want to attend? “It’s Warhol. He is a legend.”

For Kevin Allton, a USI instructor in English, Warhol was also a legend. He said, “Andy Warhol was the center of the Zeitgeist for the 20th century and everything since. He is a post-modern diety.”

Allton said he had only seen the Silver Clouds installation before in film. The Silver Clouds installation were silver balloons blown up with helium, and those balloons filled one of the smaller rooms in the gallery. “I thought that in real life it was really kind of magical,” Allton said. “I smacked them around.”

Elements of the Zeitgeist were also playfully recreated on USI’s opening night. In her opening remarks for attendees, Waters pointed out those features to attendees, noting the touches of the Warhol Factory, or the studio where he worked, that were present around them. She pointed to the refreshment table with Campbell’s Soup served with “electric” Kool Aid and tables adorned with colorful gumball “pills”. The music in the background was from such bands as The Velvet Underground.

The big hit of the evening, Wikinews observed from the long line, was the Polaroid-room where attendees could wear a Warhol-like wig or don crazy glasses and have their own Polaroid taken. The Polaroids were ready in an instant and immediately displayed at the entry of the exhibit. Exhibit goers then became part of the very exhibit they had wanted to attend. In fact, many people Wikinews observed took out their mobiles as they left for the evening and used their own phone cameras to make one further record of the moment — a photo of a photo. Perhaps they had learned an important lesson from the Warhol exhibit that cultural events like these were ripe for use and reuse. We might even call these exit instant snap shots, the self selfie.

Legendary boxing great Muhammed Ali died on Friday aged 74 in a hospital in Phoenix, Arizona in the United States. A family spokesperson said Ali had been admitted with respiratory problems. The former heavyweight champion lived with Parkinson’s disease for decades, diagnosed in 1984.

Born on January 17, 1942 as Cassius Marcellus Clay, he changed his name to Muhammed Ali after his 1964 conversion to Islam. In his professional career, Ali won 56 out of 61 fights — including 31 consecutive wins. He won the World Heavyweight Championship three times and had also won an Olympic gold medal in the light-heavyweight category.

Often considered the greatest boxer of all time, Ali was the world heavyweight champion in the 1960s and 1970s. His famous fights with George Foreman in 1974 when he won his title back and against Joe Frazier are considered by many as two of the greatest fights in the sport’s history. Ali had also defeated Sonny Liston to claim the championship title.

Ali was also known as a political activist. He came under considerable controversy after his decision to refuse the Vietnam War draft.

He lit the flame in the 1996 Olympics hosted in Atlanta.

His funeral is to be in Kentucky.

A team of researchers from the University of Tennessee, Knoxville, has confirmed that near-Earth asteroid (29075) 1950 DA is primarily held together by van der Waals forces rather than gravity. They have shown that the rotation rate of the 1.1 km asteroid is higher than could be possible if only gravity and friction were responsible for holding it together. Cohesive forces prevent large scale shedding of material and breakup of the asteroid. Their study was published Wednesday in Nature.

The researchers found that the bulk density 1.7±0.7 g/cm³ of the asteroid is approximately two times lower than the value required for self-gravity to balance out the centrifugal forces caused by rotation. As Ben Rozitis, a planetary scientist and a co-author of the study, told Space.com: “I was expecting to find a high-density metallic asteroid, as such an asteroid wouldn’t require cohesive forces to hold itself together under its fast rotation. Instead we found the opposite! […] We knew from previous work that this asteroid was rotating faster than it should be, and we wanted to know why”.

Spectral observations of 1950DA indicated that it is either an E- or M-type asteroid in the Tholen classification. However, its low optical albedo and low radar circular polarization ratio (a very smooth surface at centimetre to decimetre scales) showed that it cannot be an E-type asteroid.

Unusually for an M-type asteroid (which are mostly metallic), 1950DA has low radar albedo. It would have been puzzling, if it was not for the Rosetta observations of 21 Lutetia, which is also an M-type asteroid with very similar low radar albedo. Researchers have used for 1950DA the same meteorite analogue which was earlier found to fit best 21 Lutetia: enstatite chondrite with grain density of 3.55 g/cm³. It allowed to calculate macro-porosity of 51±19%, indicating that 1950DA is a rubble-pile asteroid.

Taking into account thermal-infrared measurements of thermal inertia, presence of a fine-grained regolith is implied, primarily around 1950DA’s equator. Negative ambient gravity near the equator of the asteroid (48±24% of its surface) requires existence of cohesive forces to prevent loss of material. This is similar to an effect noticed between the fine grains of regolith on the Moon. Lunar regolith was found to be highly cohesive because of van der Waals forces between grains by the Apollo 17 expedition in 1974.

As Ben Rozitis explained: “We found a low-density rubble pile that traditionally would be unable to hold itself together unless cohesive forces were present. It’s exciting because we’ve provided the first evidence that cohesive forces are important for small asteroids, which had only been predicted up until now.”

The balance between cohesion and negative gravity requires small grain sizes consistent with the grain size distribution on 1950DA, and similar to that of another rubble-pile asteroid, (25143) Itokawa. Unlike Itokawa, 1950DA does not have large boulders on the surface; they may have been lost as 1950DA’s rotation accelerated due to YORP effect. This effect results in a change of the rotation rate of an asteroid (either faster or slower), and is caused when the Sun heats up an object unevenly, due to asymmetric surface topography. As the heat escapes, the rotation rate is slowly changed due to an uneven rate of cooling. The researchers find that a rubble-pile asteroid may have a high rotation rate, if it is held together by cohesive forces between the grains. But as the spin rate increases due to YORP effect, the centrifugal force may cause the rubble pile to eventually separate as it happened with P/2013 R3.

The findings may have implications for asteroid impact avoidance. A very small impulse may break one potentially hazardous object into several pieces. As Ben Rozitis said: “You’d want to avoid interacting with the asteroid directly. An alternative is to use a ‘gravity tractor,’ or a heavy spacecraft placed near the asteroid, which uses the force of gravity to pull the asteroid off course”. Bong Wie, an aerospace engineer at Iowa State University in Ames, noted: “I just hope that an asteroid on a collision course with Earth will not be spinning rapidly and it will not be a rubble-pile asteroid”.

According to Daniel Scheeres, an aerospace engineer at the University of Colorado, Boulder, understanding such cohesive forces may also be important for future asteroid mining. Ben Rozitis clarified: “Mining missions intend to visit small asteroids about 10 meters (33 feet) or less in size, as it is thought that they are predominantly solid bodies. However, cohesive forces enable such small asteroids to be rubble piles instead. A small rubble-pile asteroid would be harder to interact with and collect, as it can easily deform or break up when subject to external forces.”

The study was supported by Jet Propulsion Laboratory, California Institute of Technology and the NASA.

On Monday, the US embassy in Turkey’s capital Ankara released a statement on their website announcing they are to resume accepting new requests for non-immigrant visas on a limited basis in the country. Shortly after the announcement, the Turkish embassy in the US capital Washington DC also announced they are to continue processing a limited number of non-immigrant visas. Last month, after a Turkish employee at the US embassy was arrested, the embassy introduced this measure to minimise how many visitors they received while they “assess[ed] the commitment of the Government of Turkey to the security of our diplomatic facilities and personnel.”

Monday’s statement by the US embassy said they had “received initial high-level assurances from the Government of Turkey that there are no additional local employees of our Mission in Turkey under investigation.” They had also “received initial assurances from the Government of Turkey that our local staff will not be detained or arrested for performing their official duties”, the statement said.

Turkey’s embassy, in their statement, said “Turkey also has very serious concerns about ongoing cases against Turkish citizens in the U.S.” ^{((tr))Turkish language: ?ABD’de Türk vatanda?lar?yla ilgili süren davalara ili?kin de türkiye’nin çok ciddi endi?eleri bulunmaktad?r} and said none of the Turkish employees working for the US embassy were under investigation for their service. However, the detained employees of the US embassy had “very serious charges” and has pending cases, Turkey said.

Turkish officials arrested two staff members this year. Metin Topuz, a Turkish employee at the embassy, was arrested on October 4 for alleged ties with Fethullah Gülen. Gülen is currently in the US, in exile from Turkey. According to the Turkish government, Gülen played a major role in last year’s failed coup which led to the deaths of more than 250 people. Last month, Ankara’s US embassy ambassador John Bass said, “We have been unable to determine why it occurred or what, if any, evidence exists against the employee.”

On March 7, Turkish police arrested Hamza Uluçay. Uluçay was a translator in the US consulate in Adana, and was accused of belonging to the Kurdistan Worker’s Party, which the Turkish government has labelled a “terror organisation”.

John Bass explained the ban was not to prevent Turkish citizens from entering the US. Turkish citizens who already have a US visa could visit the country. And they could apply for visas from embassies outside Turkey, Bass clarified in the statement.

In regards to the latest assurance from the Turkish government, the US embassy said “the security posture has improved sufficiently to allow for the resumption of limited visa services in Turkey.”
