According to press releases from the French Nuclear Safety Authority (ASN), Unit 2 of the Penly Nuclear Power Plant in France shut down Thursday afternoon after operators were alerted to “small quantities of burning oil.” The plant is operated by Électricité de France (EDF). Emergency crews were dispatched to the 1,330-megawatt French reactor following an alarm triggered there at 11:20 UTC Thursday. According to EDF, there were “no consequences for the environment” and no one was injured.

The ASN said in a statement the anomaly had been provisionally placed at level 1 on the International Nuclear Event Scale, which ranks occurrences at nuclear power plants on a scale ranging from 1 to 7, with 7 representing an event with lasting consequences for health and the environment such as the Fukushima Daiichi disaster following a Tsunami in Japan in March 2011.

The alarm was triggered after two fires broke out in the reactor building. The fires are reported to have been caused by leaks in one of the cooling pumps that are part of the reactor’s cooling system. The source of the fire was determined to be one or more pools of oil which had leaked from one of a pump’s joints, catching fire. They were quickly suppressed and the reactor remains shut down due to damage to the cooling pump.

After the fires were put out, radioactive water was then discovered to be leaking from the pump into the reactor’s drainage bin.The ASN released a statement at 05:00 UTC saying they had received “confirmation by EDF that the leak in the primary pump n°1 of the reactor n°2 at the Penly NPP had stopped.” ASN has undertaken an investigation into the causes of the incident which will later be published on their website. The reactor will remain shut down until the damage is repaired and the cause of the incident is known.

The Penly nuclear site, located on the coast to the northwest of Paris, is home to two Pressurized Water Reactor (PWR) units and is cooled using water from the English Channel. PWRs are a common variety of nuclear reactors named for their use of highly pressurized water in their primary cooling systems. All of the 58 nuclear power plants which supply France with over 75% of its energy, are of this type.

A firm in Oxford, United Kingdom has recently released plans for a hypersonic passenger airplane able to travel at speeds up to Mach 5 with a range of 20,000 km. Reaction Engines of Oxfordshire says the A2 plane could be in service within 25 years, carrying 300 passengers at a top speed of almost 4,000 mph, which is twice the speed of the Concorde. It would be able to reach Australia from Brussels Airport, Belgium non-stop in just five hours.

It is 143 meters (469 feet) long, which is approximately twice the length of the Airbus A380 and would be the first man-made object to cruise for extended periods at such speeds within the Earth’s atmosphere. Man-made aircraft have travelled this fast before; they, however, were inefficient rocket powered aircraft, that were only capable of short range.

The cost of a trip on the A2 is expected to be comparable with current first class tickets on standard flights, of around US$6,900 (£3,500), although it is possible prices will drop in the future.

“The A2 is designed to leave Brussels international airport, fly quietly and subsonically out into the north Atlantic at Mach 0.9 before reaching Mach 5 across the North Pole and heading over the Pacific to Australia,” said Alan Bond, the head of Reaction Engines.

Due to the heat generated in high-speed flight, the plane would have no windows. Instead, television screens connected to video cameras on the outside of the plane will be placed in front of passenger seats.

The jet may be more environmentally friendly than other planes because it uses liquid hydrogen for power rather than fossil fuel, and thus would not necessarily produce any pollution during the flight. The energy to produce the liquid hydrogen could come from an environmentally friendly source.

“Our work shows that it is possible technically; now it’s up to the world to decide if it wants it,” Bond said.

In the November issue of the Journal of Clinical Investigation,researchers announce that they have found that cannabinoids promoted a generation of new neurons in rats’ hippocampi. The study held true for both a plant-derived and a synthetic cannabinoid. The hippocampus is a part of the brain that contributes to learning and memory. In particular, it has been shown that the hippocampus is essential for the formation of new episodic memories.

“This is quite a surprise, chronic use of marijuana may actually improve learning memory when the new neurons in the hippocampus can mature in two or three months,” said Xia Zhang, with the Neuropsychiatry Research Unit of the University of Saskatchewan.

“Our results were obtained from rats, and there’s a big difference between rats and humans,” added Zhang, “So, I really don’t know yet if our findings apply to humans. But our results indicate that the clinical use of marijuana could make people feel better by helping control anxiety and depression.”

Zhang and his co-workers performed behavioral tests on two purified cannabinoids. The test results indicated that these two cannabinoids have anti-anxiety and antidepression-like effects in rats that may depend on the ability of cannabinoids to promote the production of new neurons in the hippocampus. Marijuana contains a complex mixture of chemicals including cannabinoids and may have somewhat different behavioral effects than the purified cannabinoids tested so far.

Previous studies examining the effects of cannabis have highlighted negative aspects of the drug’s use, such as short term memory difficulties, increased heart rate, nausea, and (in a very small percentage of people) hallucinations. Long term studies about cannabis use tend to be controversial as the data is seen to be biased or flawed. The most agreed upon effect of long term cannabis use is lung damage. However, proponents argue that the correlation between cannabis consumption and lung cancer is misleading suggesting that cannabis use may correlate with tobacco use or that the data is not being properly analyzed.

While nearly all coverage of the 2008 Presidential election has focused on the Democratic and Republican candidates, the race for the White House also includes independents and third party candidates. These parties represent a variety of views that may not be acknowledged by the major party platforms.

Wikinews has impartially reached out to these candidates, throughout the campaign. We now interview independent Presidential candidate Frank Moore, a performance artist.

Fifteen people were killed and twelve were injured after an eight hour hotel fire in Tuguegarao City, Northern Philippines, however police and firefighters managed to save many guests. Reports suggest the deceased sought cover in bathrooms where they were burnt beyond recognition.

After entering the building firefighters were left in tears after finding the charred bodies of guests on the upper floors. “It’s so close to Christmas, we wept when we saw their bodies,” said fire investigator Daniel Abana. Nine of the deaths were confirmed to be nursing students from a nearby university. The students were in the city to take nursing exams. Nursing college instructor, Romeo Opido, told authorities that 36 nursing students from nearby provinces were at the hotel. Tuguegarao City counselor said, “It is very unfortunate that this happened just when they were about to take their exams.”

The other deaths were the hotel owner’s and their family, including three children. The cause of the fire is still undetermined although it is known that the fire started on the ground floor and was energized by car tires and other combustible materials. It is also believed that paint cans were still in the building following a recent make over.

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.

Twenty-four cars of a west-bound Canada Pacific train were thrown from the tracks after the train collided with a semi tractor-trailer in poor weather and visibility near Regina, Saskatchewan around 11 a.m. Tuesday morning. The driver was rushed to hospital.

The accident took place on a level section of Highway 46 just north of Highway 1, about 25 kilometres east of Regina. The RCMP spokesperson reported the crossing is marked with lights, but weather may have played a role.

“Road conditions were wet and sloppy and it’s foggy,” RCMP Cpl. Brian Jones said to the CBC. The bad weather, including a heavy overnight snowfall, may have contributed to the accident.

Most of the 93 cars in the train were empty bulk transit cars, used for moving agricultural products such as grains. The RCMP report that neither train or truck were transporting any hazardous materials.

In a music-themed media event yesterday, Apple Inc. unveiled three new iPod portable music players, as well as an upgraded Apple TV system. Apple also announced updates for its iTunes software and iOS mobile operating system.

The annual event started at 10 a.m. PDT (1700 UTC) in the Yerba Buena Center for the Arts in San Francisco, California. Apple CEO Steve Jobs, who led yesterday’s keynote speech at the event, was dressed in his typical black long-sleeved shirt, blue jeans, and tennis shoes. He began by discussing new international Apple Stores, an update to the company’s iOS mobile operating system, and the release of a new gaming app, Game Center. Jobs then turned his attention to what he called the “entrée” of the day.

Apple will release new versions of its iPod Shuffle, iPod Nano, and iPod Touch lines next week in what Jobs called “the biggest change in the iPod line ever.” The iPod Shuffle’s VoiceOver capabilities have been extended to playlists, meaning that it will now be able to read off the names of songs, artists, and playlists. The new device is priced at US$49.

Jobs also showed off the company’s new iPod Nano. The Nano, now smaller and without a click wheel, features a new multi-touch screen that allows users to touch virtual buttons to control the device. The new design is 42 percent lighter and 46 percent smaller, but still includes functions on previous Nanos, such as an FM radio and a pedometer. The 8 GB version will cost US$149, while the 16 GB version will be priced at US$179.

Jobs announced an updated iPod Touch as well, an announcement that had been widely expected for some time. The new, thinner Touch has been upgraded with features matching some already on the company’s recently-released iPhone 4, including the high-resolution “Retina” display and dual video cameras. One camera, located on the back the of the iPod Touch, is for recording video, while the other camera, located on the front, is for use with Apple’s FaceTime video calling program. FaceTime allows users of the latest iPhone and iPod Touch models to conduct video chats with each other over Wi-Fi networks. The iPod Touch starts at US$229 for a 8 GB model, US$299 for 32 GB, and US$399 for 64 GB.

Another major product refresh unveiled yesterday was the Apple TV. The digital media receiver was first released in 2007, but was never very popular. Jobs even admitted that, although Apple has “sold a lot of them, they’ve never been a huge hit.” The US$99 second-generation Apple TV is both smaller and cheaper than its predecessor, which was priced at US$229. The new version will let consumers stream content from online sources, including Netflix, and rent both movies and television shows. Apple has made a deal with Fox and ABC to let users rent episodes of shows for 99¢, instead of buying programs. “We think the rest of the studios will see the light and get on board with this pretty fast,” added Jobs. High-definition movies can be rented for US$4.99, and the new Apple TV will be available for purchase in around four weeks.

Among the less-hyped updates was one to AirPlay, previously named AirTunes. AirPlay lets users stream music, photos, and videos from iOS devices to other Wi-Fi-enabled systems. AirPlay would let a video on an iPad be played on a television via Apple TV.

Along with an iOS update came one for Apple’s online music store application, iTunes. The biggest news involving iTunes 10, which is available for download now, is Apple’s new music-based social network, Ping. “It is sort of like Facebook and Twitter meet iTunes,” described Jobs. “It is not Facebook. It is not Twitter. It is something else we’ve come up with. It’s all about music.” Built into iTunes, Ping allows a user to follow both friends and artists to find new music and concert tours, and anyone with an iTunes account will be able to access Ping upon updating to iTunes 10. Ping will have settings for privacy as well, giving users the option to approve followers. Jobs also introduced a new iTunes logo, which does not include an image of a CD on it because music sales on iTunes are expected to overtake CD sales soon.

Jobs concluded the event by bringing out Chris Martin, a member of the award-winning band Coldplay. Martin, who played a few songs on the piano, including the hit song “Yellow,” jokingly called his performance “the toughest closing gig I’ve ever had.”

Although many of yesterday’s announcements had been predicted ahead of time, some had speculated that Apple would go even further. Apple defied expectations of a new cloud-based music service. They also did not extend the amount of time a buyer could sample music on iTunes, as some had guessed.
