Cambridge, Massachusetts —Construction of two condominium buildings and a five-acre park began on March 21, in East Cambridge, Massachusetts. The buildings and park are part of the 45-acre Northpoint development, which will take 15 years and more than $2bn to complete, according to the Boston Globe. The buildings, designated as “Building S” and “Building T” by the planners of the project, Spaulding & Slye Colliers, have been designed by local architectural firm Childs Bertman Tseckares and Architects Alliance from Toronto. Buildings S and T are the first of an eventual 20 buildings planned at the site.

The development will fill what used to be a railroad yard for the Guilford Rail System, a subsidiary of Guilford Transportation Industries. According to Hoovers.com, Guilford is controlled by Timothy Mellon, heir to the Mellon banking fortune. Guilford Rail Systems has its headquarters in North Billerica and owns 1600 miles of railroad throughout New England. The tracks in the Northpoint plot have been removed, though Boston subway’s Lechmere station remains within walking distance of the site, along with parts of Boston and Cambridge. The site is bordered by Route 93 on its eastern side, Monsignor O’Brien Highway to the west, and the Gilmore Bridge to the south.

The landscape architecture of the park is provided by Michael Van Valkenburgh Associates, a landscape architecture firm on Concord Avenue in Cambridge. The firm’s principal teaches in Harvard’s Graduate School of Design. MVVA is also completing the landscape for Harvard’s Northwest Science Building.

On Sunday afternoon, a Lafayette-based Petroleum Helicopters Inc. (PHI, Inc.) helicopter bound for the offshore oil fields crashed shortly after taking off from its Amelia base, into a marshy area near Bayou Penchant about 100 miles southwest of New Orleans. The helicopter had been carrying oilfield workers and 2 pilots. Eight people were killed and the Coast Guard helicopter rushed the lone survivor, a 28-year-old medevacted man, in critical condition, to Leonard J. Chabert Medical Center and then taken to Houma‘s Hebert Medical Center.

According to Pamela Norton, age 37, a Gretna woman, her ex-husband, Jorey A. Rivero Sr., age 35, of Westwego, was aboard the oil-services helicopter. “He got onto that chopper about noon Sunday,” she said. The largest helicopter company in the world, Petroleum Helicopters Inc. (PHI, Inc. – formerly Petroleum Helicopters International) has its home base in Lafayette Regional Airport. It provides helicopter services to oil and gas businesses and also flies medical helicopters. “Eight deceased passengers were recovered by the Terrebonne Parish Sheriff’s Department,” Coast Guard spokeswoman Jaclyn Young said. According to Richard Ravinelli, PHI Director of Human Resources, the victims’ names would not be released until all family members concerned are duly notified.

According to Barbara Bryant, her son who worked for three years on oil rigs, was one of the fatalities. “He just spent 3 months offshore, just because he wanted to save up enough money for a down payment on his own house, and he’s been living with me to save his money to do that. He didn’t make it,” she said.

The New Orleans Eighth Coast Guard District Command Center received a distress signal from the Langley, Va. Air Force Rescue Coordination Center (AFRCC), at 3:30 p.m. Helicopter owner PHI earlier called the Coast Guard, informing about a distress call from its helicopter. Upon AFRCC request, Coast Guard’s Air Station New Orleans’ HH-65C and crew were dispatched to the site of the crash.

Rescue workers at Bob’s Bayou Black Marina in Gibson, Louisiana, an unincorporated community in Terrebonne Parish, Louisiana, arrived at boat launch to coordinate recovery efforts for the bodies in the wilderness. The Terrebonne Sheriff’s Office Water Patrol and a Coast Guard helicopter also cooperated in search of bodies in waters near Bayou Penchant, a soupy, grassy area which is only accessible by airboat.

Federal investigators led by the National Transportation Safety Board are scheduled to arrive to the crash site Monday to probe the tragedy.

In June, another PHI Air medical helicopter also crashed in Texas. The Sam Houston National Forest accident killed the pilot, paramedic, nurse and a patient who was being transferred from Huntsville to Houston.

The Red River at Winnipeg is almost clear of ice blocks and ice jamming, however there are still dangers from the Red River flood.

Ice blocks which were as high as two storey buildings were ripping out trees, fences and railway ties. “You’ll see huge pans of ice standing vertical, up to 20 feet (6.1 m) high,” said Steve Topping, an official with the provincial Water Stewardship Department. “Ice was shoved up on the shore and took out trees with a very devastating effect. It has changed people’s view of the river.”

“It is incredible, the force. One piece of ice pushed out of the river about 20 feet. You watch the force push this up right in front of your eyes,” said Dean North, of the Selkirk Golf and Country Club.

Royal Canadian Mounted Police are ticketing sight seers who are driving through road closure signs and approaching excavators, cranes and crews breaking up the ice. Vehicles, people, boats, and kayaks are getting in the way.

An eight year old boy is in critical condition after slipping on a culvert Thursday. He was pulled underwater by the speed of the flowing water and remained under for about five to ten minutes until adults could rescue him. The air ambulance supplied by Alberta’s STARS (Shock Trauma Air Rescue Society) remains in the city of Winnipeg, Manitoba.

“This is not a spectator sport. It’s not about getting the best pictures for the family albums. I know floods are seen as a bit of an event, but some of the instances I’m hearing about, people should give their head a shake, they really should,” said Steve Ashton Manitoba Emergency Measures Minister, “Those who fall into the river or get into trouble in another way would be not only endangering themselves but the emergency response crews trying to rescue them. I don’t want to see a situation … where we’re trying our darndest to prevent flooding and save lives and somebody [who] decides to go have a white-water experience ends up killing themselves.”

Early Easter Sunday morning floodwater reached the rural municipalities of St. Andrews and St. Clements north of Winnipeg. Residents were sent an evacuation advisory Good Friday, however some residents remained. Rescue efforts commenced Saturday night to find those stranded and unable to leave as their vehicles cannot travel in the swollen overland floodwaters. Some people were rescued from roof tops as entire houses were swept off of their foundations by the large ice blocks hurtling down the river.

Highways in the area remain closed. Neil Gobelle, of Manitoba Infrastructure and Transportation said to “definitely continue to watch the Red River Valley and north of the city up in the Selkirk area. Things are changing quite a bit, quite quickly, so we’ll keep an eye on those areas.”

As of Easter Sunday, Winnipeg is expected to be ice free on the Red River. The River rose 4 feet (1.2 m) in the course of 24 hours. Rain is in the forecast and the higher temperatures of 17 °C (62.6 °F) will cause melting of snow and ice.

A weather system caused by La Niña is being watched by the United States National Weather Service and its potential effects between April 16-18 for residents along the Red River Valley. “We want people to be aware there is a very real possibility of the river going higher than what is out there,” said Mark Ewens, data manager at the NWS, “To have spring floods like this back-to-back is just an unfortunate series of events that have come along to plague us this spring. We’re wanting people to understand that this is a potentially serious problem.”

The 10.10 version of Ubuntu (codename Maverick Merkaat), a free operative system is to be released in the next few days. French Wikinews contributor Savant-fou (Baptiste) has interviewed Fabrice (fabrice_sp on Ubuntu), an Ubuntu’s MOTU (Master Of The Universe), member of the development team of the operative system.

Ubuntu is a computer operating system, based on Debian, which is created collaboratively by thousands of people. There are three official Ubuntu versions: Ubuntu Desktop Edition (for desktop and laptop PCs); Ubuntu Netbook Edition (for netbooks); and Ubuntu Server Edition (for use in servers).

Friday, August 19, 2005The Australian Federal Government has revealed today that it is going to give A$21 million (US $15.76 million) as compensation to approximately 600 former RAAF maintenance workers, who where exposed to highly toxic chemicals while working on the fuel tanks of the nation’s F-111 fleet.

Under the government’s proposal, depending on the amount of exposure, a worker can expect to receive between A$10,000 and A$40,000 (US $7,500 – $30,000) to help cope with the side effects. The aircraft maintenance program started in the 1970s and was suspended in the late 1990s when the former workers started to show signs of medical problems ranging from memory loss to neurological problems.

The F-111 Deseal/Reseal Support Group responded to the government’s package with anger. The Group’s president Ian Fraser said “A$40,000 for a ruined life is simply not enough … We’ve already got people who have died, who are dying, people who have lost their homes.”

He went on to describe that his group, which supports the workers and contractors who where based at Amberley Air Base, was “at war” with Veterans’ Affairs Minister De-Anne Kelly.

Dogs can be trained to detect early and late stages of lung and breast cancer accurately according to a study published by California scientists in the little-known scientific journal Integrative Cancer Therapies.

The study took place over the last five years at the Pine Street Foundation, a non-profit organization which conducts evidence-based research on integrative medicine (combining complementary and alternative medicine and mainstream medicine). Michael McCulloch and colleagues used three Labrador Retrievers and two Portuguese Water Dogs, both common pets, that received basic behavioral dog training. The researchers trained the dogs to lie down next to a sample from a cancer patient and to ignore other samples.

The samples used were breath samples from 55 patients with lung cancer and 31 with breast cancer — the two types of cancer with the highest mortality rates in the United States.

After the training phase, the dogs’ accuracy diagnosis was tested in a double-blind experiment. Among lung cancer patients, the sensitivity and specificity were 99% accurate and for breast cancer sensitivity was 88% and specificity 98%. Because these figures seem almost too good to be true, cancer experts are the same time baffled and skeptical. The authors of the study themselves also say replication of the study is needed.

Importantly, this was independent of the cancer stage, meaning the dogs were able to pick up the scent of cancer in its early stages. This is important because in many cases, the success of any treatment depends on early diagnosis. However, the researchers don’t believe this will lead to the use of dogs in the clinic soon, rather they want to find out which chemicals are actually sensed by the canines, because they could be used in laboratory assays. “It’s not like someone would start chemotherapy based on a dog test,” Dr. Gansler of the American Cancer Society said, “They’d still get a biopsy.”.

The researchers were inspired by anecdotal reports about dogs detecting cancer. In 1989, a British women consulted with her family physician because her Dalmatian kept licking a mole on her leg. At biopsy it showed to be malignant melanoma. When diagnosed too late this form of cancer has a poor survival rate, but in this case early surgery was made possible, and the women survived. Prior studies showed that breath samples from patients with lung cancer or breast cancer contain distinct biochemical markers. This provides a basis for the hypothesis that some cancer types produce volatile chemicals that dogs could smell. A study published in the British Medical Journal already proved that dogs could use their exquisite sense of smell to detect bladder cancer in urine samples, but they were only correct in 41% of cases, and another study provided preliminary evidence that dogs could detect melanomas.

This doesn’t mean you can show your breasts to your dog and it will tell you if you have cancer, other physicians caution, and scientists do not advise people to train their dogs to sniff for cancer. Unresolved issues from the study include the fact that subjects were required to breathe deeper than normal, so it’s not sure whether dogs can smell cancer in normal breath. Also, whether this is a permanent skill that would be retained by dogs was not tested.

Finally, there are concerns that could arise over liability issues: who would be responsible when the dog makes a mistake?

Current detection methods for both lung and breast cancer are not flawless. For lung cancer, chest X-ray and sputum cytology (detecting cancer cells in coughed up fluid) fail to detect many early cases, and CT scan produces many false-positive results unless combined with expensive PET scans. Although it might be comparing apples and oranges, a $2.5 million CT scanner has an accuracy of 85 to 90%. Mammography also produces false-positive results, and it may be difficult in women with dense breast tissue. As such, another type of “pet”-scan, using dogs as a biological assay, might prove feasible for screening if supported by further research. Current tests are also expensive so the use of dogs for preliminary cancer testing could prove to be an affordable alternative for countries in the developing world.
