Officials with the US Marine Corps have announced their investigation into the fatal crash of a Bell Boeing V-22 Osprey transport plane on April 11 has found pilot error was to blame. The probe found two marines died after the pilots lost control in a tailwind in Morocco.

The accident has triggered attention from Japanese media ahead of a planned deployment there, and officials at a press conference Friday were keen to stress no mechanical or structural defects were found. The pilots had opted for an unplanned 180-degree turn to avoid flying low over obstructions including people and vehicles. This move placed them into a strong tailwind.

This wind tilted the plane forward, but the pilots did not realise and began rolling the engines forward. The Osprey had been flying in helicopter mode, with the rotors pointed skywards; by pointing them forwards, it can be operated as a standard aircraft. Normal flight rules call for the aircraft being level, not tilted, when this switch is made.

These actions moved the center of gravity forward, which pitched the nose further down. Pulling on the flight column was insufficient to correct the problem, and the aircraft flew down into the ground. Two Marines in the back were killed, and both pilots were seriously injured. The investigation suggested leaving the aircraft in helicopter mode could have prevented the accident.

The wounded pilots are still recovering, and Marine Corps Aviation’s deputy commandant Lt. Gen. Robert Schmidle said that when they are well enough they will go before a panel to determine if they are fit to fly. He says their actions will be scrutinised then. Schmidle also said the model’s flight manual will be updated and training given to pilots in light of the crash.

“It’s an extraordinarily complex set of circumstances that caused this to happen”, he told reporters Friday. He called the plane a “solid, safe” model.

Poison control centers across the US are monitoring a recent increase in the trend of teenagers getting drunk by consuming hand sanitizer. In an effort to educate the public about the trend’s detrimental effects, these centers will be publicizing preventative methods, according to James Mowry, director of Indiana Poison Center.

“We are going to keep a close watch on this trend,” said Mowry. “We will be posting information on our Facebook page so our public will be aware of what could happen.”

Sixteen cases have been reported in California since March 1, according to the California Poison Control System. This amount raises California’s total to 60 cases reported since 2010.

Since the system “only receives the reported cases,” said Stuart E. Heard, executive director at CPCS, “… we suspect there are much more that go unreported.”

Ingesting the product can cause severe internal damage. The US Food and Drug Administration considers hand sanitizer a drug because the active ingredient in the product is alcohol. Low numbers of reported cases will not stop poison control centers from educating the public on the trend’s harmful effects, according to Mowry.

Hand sanitizer contains 62 percent ethyl alcohol and, when ingested, produces the same effects of consuming a 120-proof alcoholic beverage or 50 percent more alcohol than hard liquor, according to Mowry. These effects range from dizziness to slurred speech. Ingesting the product can also lead to severe internal damage including alcohol poisoning. Alcohol poisoning symptoms include confusion, vomiting, seizures, slow or irregular breathing, blue-tinged or pale skin, low body temperature, and unconsciousness, according to a report from the American Association of Poison Control Centers.

“Teens may ingest hand sanitizer recreationally, and one or two swallows could get a child visibly drunk. The larger the bottle, the greater the potential for poisoning,” said Cyrus Rangan, a medical toxicology consultant at the Children’s Hospital Los Angeles and an assistant medical director at CPCS.

Teenagers learn how to extract the alcohol from the product through various sources, like YouTube tutorials. A common method of distilling hand sanitizer involves using salt to isolate the alcohol. Other teens boil the product to separate the ethanol.

“Methods to distill it can be found through friends and the Internet, but straight ingestion of the product without distillation is also common,” said Rangan. Another concern with this trend is the product’s availability. “Hand sanitizer is readily available,“ said Heard. “Teens can buy it anywhere.”

Officials suggest parents keep hand sanitizer out of children’s sight and reach. Also, purchasing hand sanitizer in foam form instead of gel makes drinking the substance less appealing. However, education is critical. “The main preventative focus should be education,” said Heard. “Teens need to thoroughly understand the effects of consuming large amounts of alcohol in a short amount of time.”

An ethical controversy has surged in the United States and elsewhere around nine-year-old Ashley X (her family name has not been released). The disabled girl was operated upon at the request of her parents, to prevent her from growing, menstruating and developing breasts. The parents, who wish to remain anonymous, explain their situation on a blog entitled The “Ashley Treatment”. There have been over 1000 reactions on the blog so far.

Ashley suffers a condition termed static encephalopathy with marked global developmental deficits of unknown etiology, which means brain damage of unknown cause leading to a kind of static condition. She can make sounds, move her arms and kick her legs, but she cannot change her position, eat, walk, talk etc. Many of these children are in poor health and die young, but Ashley is in good health. For all of these functions she depends on her caregivers. Most of the day she passes watching her surrounding, lying on a pillow. Her parents call her their “Pillow Angel”, “since she is so sweet and stays right where we place her—usually on a pillow.”

Ashley’s parents want to keep her at home and care for her themselves, and they want to guarantee their daughter’s quality of life. To this end, they say, Ashley underwent several surgical procedures and medical treatments during a period of three years. To attenuate her growth, Ashley was given high doses of the hormone estrogen. Ashley now measures 4ft 5 (1m 35cm) and weighs around 75 lbs (34 kg), which is below her expected length and weight. Her low body weight and size would improve her comfort, and at the same time facilitate the work of her caregivers.

Surgery to remove her uterus (a procedure called a hysterectomy) and breast buds were performed, so Ashley does not menstruate and will not develop breasts, both of which parents think only would cause her discomfort. Since high estrogen levels can cause menstrual bleeding and breast development, the surgery was also meant to limit these effects. She also underwent surgery to remove her appendix, because it would be difficult to diagnose appendicitis given Ashley’s low communication possibilities.

Another population of small humans has been reported, this time in caves in Micronesia.

Lee Berger, Steven Churchill, Bonita De Klerk and Rhonda Quinn, a team of paleontologists and anthropologists from South Africa and the United States document a group of “small-bodied humans” found in the ” in limestone caves in the rock islands of Palau, Micronesia.” The report, in a recent edition of the open access journal, PLoS ONE (2008 3:3) argues that these small people may “represent a congenitally abnormal individual drawn from a small-bodied island population of Homo Sapiens.” The term for this condition is Insular Dwarfism described in Foster’s Rule. Different radio carbon samples at the site date between 3000 and 4500 calendar years before the present, with the 3000 year old dates being judged the most reliable.

The authors argue, “Based on the evidence from Palau, we [Berger et al] hypothesize that reduction in the size of the face and chin, large dental size and other features noted here may in some cases be correlates of extreme body size reduction in H. sapiens.”

Unlike the 2004 find of the Flores dwarf human population (dated from 95,000 to 13,000 years ago), known as Homo floresienses and nicknamed hobbits, researchers do not consider this population to be a separate hominid population. They also suggest that this more recent population casts some doubt on H. floresienses being a separate species, and that,

“These features when seen in Flores may be best explained as correlates of small body size in an island adaptation, regardless of taxonomic affinity…[This] Palauan sample supports at least the possibility that the Flores hominins are simply an island adapted population of H. sapiens, perhaps with some individuals expressing congenital abnormalities.”

In support of this, Berger et al also argued that although the dwarf humans appeared to have many features in commons with Homo sapiens, there seems to be many features that are not usually associated with Homo sapiens.

Wikinews spoke to several residents of the US state of Texas finding varying opinions, and responses, to the threat from the West Nile virus; this, in contrast to the troubling media reports released recently. The state as a whole has seen more than 400 confirmed instances of the illness so-far this year.

A Longview woman, said, “[…] It’s terrifying. I’m so scared.” The woman was quick to point out a virus-related death occured in her city the same day. When asked about her daily routines, in light of the virus, she said, “I don’t go outside. I stay indoors. West Nile [virus] is bad.” The Director of Nursing for a large encampment located near Tyler said their operation had seen no cases of the illness, despite serving over 19,000 campers this summer. Her staff took no special precautions during August.

Although having some worries, Jimmy Philmont, 39, of Fairfield told Wikinews, “[…] I don’t let it keep me up at night. Overall, I’m not too scared.” Asked if he was aware of recent virus-related deaths in Texas, Philmont said, “Yeah, I am. That’s kind of scary. But, you have to live your life, you know? The world is hot now. You can’t go hide in a hole somewhere.” Earlier in the month, Tim Whitley, a city official in Malakoff, told Wikinews his city had began using a pesticide specialist to spray twice-weekly. Whitley explained two treatments per week is more often than usual for the city, “With the concerns in Dallas, we’re taking it seriously”, he said.

A nurse at a senior activity center in Austin told media she’d taken time to educate their facility’s clients about the virus and proper precautions; Adding, “They feel less alarmed and we try to protect our folks here […]”. Mark Kitsmore, 54, of Tyler said, “Honestly, I’m not too worried about it.” He jokingly commented, “I’ve probably used a little more bug spray over the past few weeks, though.”

Twenty-six people have died so-far this year as result of having contracted the virus, approximately half occurring in Texas. The mayor and county judge in Dallas have declared a state of emergency in response to the virus.

The President of the Italian Republic, Giorgio Napolitano, has asked Romano Prodi today to stay on as Prime Minister, but Prodi will need to pass a confidence vote as soon as possible. After two days of consultation among Italian party leaders, Napolitano called on Saturday a press conference to explain his decision.

Napolitano stated that Prodi’s coalition, l’Unione, is ready to support unanimously its Prime Minister, above all after the drafting of the twelve points agreement about the main political issues. The President rejected the proposal from the centre-right opposition to call for fresh elections, because Italy needs a new electoral law, and there was no consensus to form a broad interim government.

The confidence votes, both in Italian Chamber of Deputies and Senate, will be held in the coming week.

Thanks to the vote of independent Senator Luigi Pallaro, Marco Follini, leader of a centrist movement, and the votes of four senators for life (Carlo Azeglio Ciampi, Emilio Colombo, Rita Levi Montalcini and Oscar Luigi Scalfaro), the centre-left coalition could trust in a majority of 162 votes in Senate. The centre-right coalition, instead, has some 155 votes, although it is unknown how the ex-senator of the “Italia dei Valori” Sergio De Gregorio and the life-senators Giulio Andreotti, Francesco Cossiga and Sergio Pininfarina will vote.

Scientists have uncovered the largest Neolithic settlement in the United Kingdom at the Durrington Walls and believe that the village was inhabited by the people who built the Stonehenge monument.

Scientists say that the village was built around 2,600 B.C., roughly when Stonehenge was believed to have been constructed, and housed over 100 people.

Inside the areas which would have been the interior of houses at the time, scientists also found outlines of what they think were beds and cupboards or dressers. Pieces of pottery and “filthy” rubbish around the site. Animal bones, arrowheads, stone tools and other relics were also discovered.

“We’ve never seen such quantities of pottery and animal bone and flint. In what were houses, we have excavated the outlines on the floors of box beds and wooden dressers or cupboards,” said Sheffield University archaeologist Mike Parker Pearson.

So far, the dig has revealed at least 8 houses roughly 14-16 feet square, but scientists say that they think there may have been at least 25 altogether.

The site was likely to have been occupied only seasonally rather than year-round and evidence suggests that a lot of “partying” went on at the location.

“The animal bones are being thrown away half-eaten. It’s what we call a feasting assemblage. This is where they went to party – you could say it was the first free festival. The rubbish isn’t your average domestic debris. There’s a lack of craft-working equipment for cleaning animal hides and no evidence for crop-processing,” added Pearson.

The Durrington Walls are approximately 2 miles from the Stonehenge site.
