An Atlas V rocket has successfully launched a classified spy satellite for the United States National Reconnaissance Office (NRO). The satellite, currently known to the public as NRO L-28, or Launch 28, is believed by amateur enthusiasts to be a signals intelligence (SIGINT) spacecraft, known by the codename Trumpet. The Atlas V carrier rocket flew in the 411 configutation, with a 4 metre diameter fairing, one solid rocket motor, and a single-engine Centaur upper stage.

The rocket lifted off from Vandenberg Air Force Base, Space Launch Complex 3 East (SLC-3E), at 10:02 GMT (03:02 local time) this morning. Today’s flight marks the thirteenth launch of the Atlas V, and the first Atlas V launch from Vandenberg. It is also the tenth orbital launch of 2008. The satellite entered a Molniya orbit, usually used by the NRO for SIGINT and communications satellites.

The launch was conducted by United Launch Alliance, a joint venture between Lockheed Martin, who designed and built the Atlas V, and Boeing, to provide EELV launches for the US Government. ULA president Michael Gass described the launch as “a proud moment in our company’s history”. The launch had been delayed by two years, from early 2006, due to a number of factors.

In addition to its reconnaissance payload, the satellite is carrying two small experiments. SBIRS-HEO 2 and TWINS-B. SBIRS is a test article for a missile detection system, slated to launch late this year or early next, and TWINS is a NASA infrared astronomy experiment. They will remain attached to the satellite for the duration of its mission.

Following the separation of the payload fairing, around five minutes after launch, all information on the launch was withheld, however about an hour into the flight, the launch was confirmed to have been successful. ULA will conduct its next launch on Saturday, when a Delta II will orbit a GPS satellite. The next Atlas launch is scheduled for mid-April, with the ICO G1 communication satellite.

The Standard Chartered Marathon, nicknamed “The Greatest Race on Earth“, held its third stage in Mumbai, India today. Because of the scorching hot weather in India, marathon runners had to adapt to the weather to overcome the challenge.

More than 30,000 runners participated in this race, joined by local NGOs and disabled who participated in a special charity short-distance running including 6km dream run, 4.3 km senior, and 2.5km wheel-chair classes. Gabriela Szabo, former Romanian Olympic Gold Medalist, named as charity ambassador of the race, was pleased by the participation from experts and NGOs.

An hour into the race, former champion Daniel Rono and Joseph Kimisi took the lead, but then Tariku Jifar from Ethiopia and defending champion John Ekiru Kelai took over Rono and Kimisi. After 40 kilometres, Kelai took a decisive lead and finally retained his champion title in 2 hours 12 minutes 22 seconds.

In the Women’s Group, Mulu Seboka from Ethiopia won the champion with 2H30m03s. Local runners Surendra Singh & Kavita Raut won the Men’s and Women’s Champions in the half-marathon class.

On June 3rd, 2008, two United States Internet service providers (ISPs) announced they would begin tests to slow web access for their most active customers and charge them for extra speed. Comcast and Time Warner Cable, two of the largest ISPs in North America, both made separate announcements of their plans. The actions come in the wake of an investigation by the Federal Communications Commission (FCC), over whether Comcast had restricted some customers from sharing videos, music, and similar files. The FCC investigation led to a US Congress debate over whether and how much control ISPs should have over the flow of customer data.

Public interest groups complained in November 2007 to the FCC that Comcast had specifically targeted customers using applications that made use of the BitTorrent system, a popular form of file sharing. Free Press, an advocacy group that pushes for better oversight of cable operators such as Comcast, stated that Comcast practices were discriminatory towards users of the legal technology. “The cable companies see a hammer hovering above their heads and are scrambling to find ways to reduce the appearance of wrongdoing,” said Ben Scott, head of the group.

According to Roger Entner, a senior vice president from Nielsen IAG, as little as 5 percent of all Internet users may consume as much as 50 percent of all the bandwidth on the Internet. “This is the politically correct version of doing what Comcast had been doing before, though it takes the occasional [peer-to-peer] user off the hook,” Entner said. Sena Fitzmaurice, a Comcast spokesperson, said, “This says we won’t be looking at what type of traffic that there is, even though we still need to manage the network.”

Comcast’s tests are expected to begin in Chambersburg, Pennsylvania and Warrenton, Virginia.

While Comcast will attempt to throttle the speed of all its high-volume users, Time Warner Cable intends to use a different method. They will meter and bill clients, charging more money for faster speeds and larger amounts of transmitted data, functioning more like a traditional public utility, such as an electric company or cell phone service. Their metered billing test will begin on June 5 in Beaumont, Texas for newly enrolled customers. “Instead of raising prices across the board, consumers who are excessive users would pay,” said Alex Dudley, a Time Warner Cable spokesman. “It is clearly the fairest way to fund the investment that is going to be required to support that use.”

An Associated Press report that Time Warner Cable will bill customers between $29.95 to $54.90USD per month has been confirmed by the cable operator, with clients charged an extra $1 for each gigabyte (GB) by which they exceed their purchased plan. Art Brodsky, communications director of Public Knowledge, a consumer advocacy group in Washington D.C., has expressed concerns about the Time Warner Cable plan. Time Warner Cable’s most expensive offering, $54.90, comes with 15 megabits-per-second of data transfer speed and a 40 gigabyte limit on total data transfer.

“An HD (high-definition) movie is 8GB or so, three movies is more than half your allowance for a month, and heaven knows what else you might want to watch,” Brodsky says. “This is not a relieving congestion scheme as much as it is a rationing scheme. All it does is protect an inadequate infrastructure from the cable company.”

A rise in flesh-eating staph infections has worried doctors about the possible spread of drug resistant bacteria.

Staphylococcus aureus, commonly known as staph, is a bacteria that commonly causes skin infections in otherwise healthy people. However, as a persistent threat in hospitals, it tends to infect patients who are already sick and whose systems are vulnerable due to IV lines that pierce the skin. Doctors have already battled for years against drug-resistant strains of the bacteria, but the struggle has generally been confined to hospitals.

Now, however, Methicillin Resistant Staph Aureus (MRSA) has been spreading in communities outside hospitals. Cases have multiplied by 25 times since 1998 at the University of Chicago. A Los Angeles hospital documented 14 cases of the flesh-eating infection, where patients required substantial time in intensive care and surgery. The infections are particularly problematic because nearly a quarter of people who get a staph infection require hospitalization.

Staph infections are spread much like other diseases, with crowded conditions, poor hygiene, and skin-to-skin contact most frequently to blame. At higher risk are prison inmates, homeless people, military personnel, and families with kids in day care. Athletes also have a higher risk, because sweating makes it easier for bacteria to infect the skin.

Last week’s police helicopter accident in eastern Slovakia was caused by technical failure and not human error, said the Ministry of Interior of the Slovak Republic on Friday. The statement is based on preliminary flight recorder data analysis. Ministry spokesperson Petar Lazarov confirmed the flight recorder and remains of the helicopter will be sent to the United States for further analysis. Helicopter crash occurred during a training exercise on May 10 shortly before 2:30 PM CEST at Prešov Air Base near Prešov, resulting in deaths of two crewmembers and serious injuries of both pilots.

According to initial reports by the Slovak Police Force, the helicopter spiraled down from a height of about 100 metres and 200 metres away from the point of take-off. Slovak tabloid newspaper Plus Jeden De? wrote that, according to a source from the forensic team that analysed flight recorders data, both rotors failed at the same time.

The accident caused fatal injuries to two Fire and Rescue Corps firefighters, First Lieutenant ^{((sk))Slovak language: ?nadporu?ík} Peter To?or, born 1974, and Lieutenant Colonel ^{((sk))Slovak language: ?podplukovník} Radoslav Lacko, born 1968. According to reports, one died on the site, and one in the Louis Pasteur University Hospital in Košice. “The patient suffered serious head and chest injuries. Our doctors resuscitated him for about 50 minutes. Ultimately, he died of his injuries,” said hospital spokesperson Ivana Stašková. Both firefighters were buried on May 16. The helicopter pilots were hospitalized with serious injuries in the Ján Adam Reiman Teaching Hospital with Polyclinic in Prešov. While one of them was stabilized and conscious already on May 10, suffering from right femoral fracture, right rib and facial bone fracture, the second one is still in serious condition at the Department of Anesthesiology and Intensive Medicine, said hospital spokesperson Renáta Cenková.

The Bell 429 GlobalRanger helicopter, registration OM-BYM, was made in 2014 and commissioned by the Aviation Department of the Ministry of Interior on August 17, 2015. The Aviation Department later commissioned another Bell 429 helicopter, registration OM-BYD. According to Bell Helicopter, the primary purpose of both these helicopters was to be “border protection, search and rescue, natural disaster relief missions and road traffic law enforcement”.

Bell Helicopter reacted on the incident, expressing condolences and willingness to assist with the investigation. Members of the National Council started their late-afternoon session on May 10 with a minute of silence for the victims of the crash. Other government officials expressed their condolences as well, including the President Andrej Kiska, the Prime Minister Robert Fico, and the Mayor of Prešov Andrea Tur?anová.

This accident was not the first Bell 429 helicopter crash in Slovakia. On September 7 of last year, an Air-Transport Europe rescue helicopter crashed near Banská Bystrica, killing all three crewmen and a patient aboard. Investigation is still in progress and no preliminary results are known.

Apple Inc. today has introduced the much-anticipated iPhone at the Macworld Conference in San Francisco.

The iPhone is claimed to be “a revolutionary mobile phone” as stated on the Apple website. The device appears to be running a mobile version of the Apple operating system Mac OSX. It is approximately the same size as a 5th generation iPod, it has a 3.5-inch LCD touchscreen display that is used to access all features of the phone including number dial, as well as making phone calls. The iPhone plays music, movies, displays pictures and is able to connect to a wireless network.

Apple CEO Steve Jobs unveiled the device by walking onto the stage and taking the iPhone out of his jeans pocket. During his 2 hour speech he stated that “Today Apple is going to reinvent the phone, We are going to make history today”.

Today Apple also released their Media Center device – Apple TV. It will directly compete with Microsoft’s Media Center operating system. Apple has taken a different approach to the media center market; rather than storing content (such as movies, music and photos) on the device, Apple TV connects to a computer (Mac and Windows) over a wirless network connection and plays all content stored on that computer. This makes it substantially easier for users to organize their media content.

In February 2017, the Iranian Chess Federation announced two teenage chess players, Dorsa Derakhshani and her younger brother Borna Derakhshani, were banned from representing the national team. The federation announced their decision although Dorsa Derakhshani had previously decided and informed the chess federation she did not wish to play for Iran.

Dorsa Derakhshani is currently 21 years old and holds the International Master (IM) as well as Woman Grand Master (WGM) titles. Her brother, Borna, plays for the English Federation and holds the FIDE Master title.

Dorsa Derakhshani was banned since she did not wear a hijab, an Islamic headscarf, while competing at the Tradewise Gibraltar Chess Festival in January 2017. Under the laws of Islamic Republic of Iran, hijab is a mandatory dress code. Her brother Borna Deraskhsani was banned for playing against Israeli Grand Master (GM) Alexander Huzman at the same tournament. Iran does not recognise the existence of Israel, and previously, Irani athletes have avoided playing against Israeli athletes.

Mehrdad Pahlavanzadeh, the president of the country’s chess federation, explained the decision to ban the players saying, “As a first step, these two will be denied entry to all tournaments taking place in Iran and in the name of Iran, they will no longer be allowed the opportunity to be present on the national team.” ^{((fa))Farsi language: ?????? ????? ?? ??? ??? ?? ??? ????? ?? ?? ???? ???????? ?? ?? ????? ? ?? ??? ????? ?????? ??????? ????? ??????? ? ???? ???? ???? ?? ??? ??? ?? ??????? ????.} He further stated, “Unfortunately, something that should not have happened has happened and our national interest is paramount and we have reported this position to the Ministry of Sports.” ^{((fa))Farsi language: ????????? ?????? ?? ????? ????????? ?????? ??? ? ????? ??? ?? ?? ?? ???? ?????? ???? ? ?? ??? ???? ?? ?? ????? ???? ?? ????? ?????.}

IM Dorsa Derakhshani, who currently studies at Saint Louis University in the United States and plays for the United States Chess Federation, discussed her chess career, time in Iran and the 2017 controversy, and her life in Saint Louis with a Wikinews correspondent.
