China has stated that they will cease all military exchanges with the United States in response to a US$6.4 billion (NT$204 billion) weapons deal with Taiwan going ahead. He Yafei, Chinese Vice-Foreign Minister, said that there would be a “serious negative impact” with regards to the relationship between the US and China.

Taiwan and mainland China have been ruled by separate governments since 1949, and neither recognize each other’s independence. In an effort to regain control of Taiwan, the government in Beijing has been open to running the island like Hong Kong, in a “one country, two systems” manner, but people in Taiwan support the status quo. The Chinese defense ministry said that they had “decided to suspend planned mutual military visits”. They “strongly demand” that the United States “respect the Chinese side’s interests,” calling for the proposal to be rejected.

China summoned the US Ambassador to China, Jon Huntsman, to warn the US Government about the consequences, and to urge for cancellation of the deal. The Pentagon proposed the deal, that was first promised during the later days of the Bush administration, to Congress earlier.

Yafei issued a statement on the Foreign Ministry website stating that “the United States’ announcement of the planned weapons sales to Taiwan will have a seriously negative impact on many important areas of exchanges and co-operation between the two countries.”

However, the US is defending itself. “Such sales contribute to maintaining security and stability across the Taiwan Strait”, Laura Tischler, spokeswoman for the US State Department, said.

Beijing is threatening to review co-operation on major issues and impose sanctions on companies selling arms, even though US companies are banned from selling arms to China as a result of the Tiananmen Square massacre in 1989, so it is not clear what the effect will be. A Chinese defence ministry spokesman said that the sanctions reflected the “severe harm” the deal would have. A foreign ministry spokesman stated that there would be “repercussions that neither side wishes to see” if the deal went ahead.

Taiwan, one of Asia’s few functioning democracies, welcomed the proposal, with Taiwanese president Ma Ying-jeou being quoted as saying “It will let Taiwan feel more confident and secure so we can have more interactions with China.”

The arms deal includes UH-60 Black Hawk helicopters, communications equipment and MIM-104 Patriot missiles, but does not include the F-16 fighter jets that Taiwan’s military were looking for. The US is legally obliged to supply Taiwan with defensive weapons under the Taiwan Relations Act 1979.

In 2003, an unnamed US briefing stated that “[the US] would have to get involved if China tried to use coercion or force to unilaterally change the status of Taiwan”.

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.

The Interstate 35W Mississippi River eight-lane bridge in Minneapolis, Minnesota has collapsed on both sides of the highway over the Mississippi River during rush hour.

Previous reports indicated at least nine people had died, but Minneapolis police revised this to four during a 7:30 a.m. (local time) press conference. Tim Dolan, the Minneapolis Police Chief later stated that “several [adding to the four] people are confirmed dead at the scene,” but would not elaborate on how many. At least 79 have been injured and at least 8 are still missing, still believed to be in the rubble.

The road was busy with bumper-to-bumper traffic in four lanes when the entire 1907 foot (581 m) steel arch bridge collapsed. At least 50 cars were traveling on the bridge, including a school bus. The Red Cross said that 60 children were aboard a school bus, and that ten of those were admitted to a hospital.

The entire length of the bridge over the river collapsed at 6:05 p.m. CDT (UTC-5). The bridge, built in 1967, cleared the water level by 64 feet; the deck surface and pavement were considerably higher.

Reports say that people may be trapped in the water. Further, “many voids may contain survivors, but we cannot search those voids until it’s safe,” said Jim Clack, Minneapolis Fire Chief, during a press conference.

“One has died from drowning,” said a doctor from the medical center during an 8:00 pm press conference, who also said that so far 22 are in “yellow condition” and at least six are in “critical condition.”

Minneapolis officials have stated during an earlier press conference that “people are being sent downtown and all survivors are off the bridge. We are seeking help from the Red Cross.” and “[…]at least 60 children are receiving trauma care some with severe injures, some with minor injuries.”

Most of the injured have been received by Hennepin County Medical Center in downtown Minneapolis for medical treatment. Area hospitals are requesting all off duty staff and all Minneapolis ambulances to report. Residents are being encouraged to stay away from the area to let emergency crews do their work.

It is not known what caused the collapse, but there was construction being performed on the bridge’s road surface which included the use of jackhammers and the FBI has ruled out terrorism.

“Although it is much too early to make any determination of the cause, we have no reason at this time to believe there is any nexus to terrorism,” said Paul McCabe, an FBI spokesman.

In 2001 a stress inspection was done and Minnesota Department of Transportation stated that the bridge “should not have any problems with fatigue cracking in the foreseeable future.”

Typically an eight-lane bridge, the bridge was reduced to four lanes (two in each direction) during the current construction. The Minnesota Department of Transportation (Mn/DOT) had just announced overnight lane reductions on the bridge to one lane in each direction for the late evening hours of July 31 and August 1.

At the Saskatchewan Association of Rural Municipalities (SARM) conference, a resolution was passed that encourages the Government of Saskatchewan, Canada to place a moratorium on specialty livestock farms raising wild boar. All wild boars that have escaped to roam wild should be killed, according to the resolution.

Agriculture Minister Bob Bjornerud endorses a ban on wild boar farming. The wild boar population is expanding exponentially. There are over 2,000 feral Sus scrofa swine roaming the prairies. Two litters of approximately 12 piglets are sired by each wild boar sow every year. The Saskatchewan Wildlife Federation (SWF) likewise passed a similar resolution at their 79th annual convention to urge the Saskatchewan Government to declare the wild boar as a nuisance species which can be killed on sight.

3% of farmed “wild” boars escape. Cells of wild boars are ravenous creatures killing and eating everything in their path. Horses, cows, and other livestock run from wild boars, breaking through fences in the process.

Ostriches, emus, llamas, alpacas, reindeer, wild boar, and fallow deer were amongst the animals introduced to farms in Saskatchewan during the agricultural diversification program in the late 1970s. Production of wild boars was promoted throughout the 1980s.

According to the Saskatchewan Agriculture and Food 2001 statistics, there were 150 wild boar producers raising approximately 15,000 and 20,000 head. Of these there were about 2,700 sows. On the 2006 Census of Agriculture, 401 farms reported 4,926 boars.

The boar’s red meat is an export commodity to Europe and Asia. The live breeding stock are also sold to trophy hunt ranches. Full blooded wild boar and hybrid crosses are raised.

Tuesday, World Bank released the 2012 World Development Report on Gender Equality and Development. In discussing Iceland, it suggests mandatory paid parental leave for mother and father have played an important role in changing norms in the country. Parents have a government mandated nine months leave, three for the mother, three for the father and three to to distribute between the two. Leave is paid at 80% of their wages. The report describes the changes in gender relations in Iceland as “promising” in terms of impact at work and at home.

Iceland’s boys and girls mean scores for the Programme for International Student Assessment mathematics test were nearly identical with boys just edging out girls with both scores around 510. Girls outperformed boys on the literacy test with a mean score of approximately 525 to 480. Iceland’s girls mathematics performance was similar to that of girls from Estonia, Germany and Belgium. Their performance on literacy was similar to Sweden, Poland, Switzerland, Estonia and Belgium.File:MargretSverrisdottir.jpg

Mortality rates in Iceland for 1,000 people aged 15–60 sits at 56, significantly better than the United States at 107, China at 113, India at 213, Iraq at 285, Afghanistan at 479, Malawi at 481 and Zimbabwe at 772. One of the reasons the report cites for Iceland’s relatively low mortality rate is it not located in a conflict country or in an HIV/AIDS affected country.

Iceland was one of 23 countries that currently have over 30% of its Parliamentarians who are female. Other countries with over 30% representation include Rwanda, Argentina, Cuba, Finland, the Netherlands, and Sweden. In the mid-1990s, there were only 5 countries. The report cites the 1983 creation of the Women’s Alliance, an all women’s political party, as bringing additional attention to women’s issues and deliberately attempting to increase the representation of women in Icelandic politics.

Despite some of the good news highlighted in the report about Icelandic women, there exists a systematic gender difference in earning potential. Icelandic women in both the private and public sector earn approximately 22% less than their male counterparts. Icelandic men have slightly more access to the Internet than Icelandic women by about 2%. Despite this slight disadvantage for Icelandic women, it is much better than some countries where the percentage differences are much greater. These countries include Austria, Croatia, Greece, Italy, Portugal, Azerbaijan, Serbia, Turkey, and Macedonia.

In Copenhagen, Denmark on Monday, the first day in the new year, scaffolding at the corner of Randersgade and Koldinggade collapsed at about 13:00 local time (1200 UTC). Strong winds were reported.

Police cordoned off the area, noting it could collapse even more and cables for the street lightning were broken.

No personal injuries were reported, but some cars were damaged, according to the Copenhagen Police.

Arbejdstilsynet, the Danish workplace safety authority, was investigating the cause of the collapse and the police planned to question the company who set up the scaffolding.
