In a press release earlier today, New York State Agriculture Commissioner Patrick Hooker, along with Dean of Cornell University’s College of Veterinary Medicine Donald F. Smith, confirmed that scientists at the New York State Food Laboratory identified Aminopterin as a toxin present in cat food samples from Menu Foods.

Menu Foods is the manufacturer of several brands of cat and dog food subject to a March 16, 2007 recall.

Aminopterin is a drug used in chemotherapy for its immunosuppressive properties and, in some areas outside the US, as a rat poison. Earlier reports stated that wheat gluten was a factor being investigated, and officials now state that the toxin would have come from Chinese wheat used in the pet food, where it is used for pest control. Investigators will not say that this is the only contaminant found in the recalled food, but knowing the identity of the toxin should assist veterinarians treating affected animals.

The Food Laboratory tested samples of cat food received from a toxicologist at the New York State Animal Health Diagnostic Center at Cornell University. The samples were found to contain the rodenticide at levels of at least 40 parts per million.

Commissioner Hooker stated, “We are pleased that the expertise of our New York State Food Laboratory was able to contribute to identifying the agent that caused numerous illnesses and deaths in dogs and cats across the nation.”

The press release suggests Aminopterin, a derivative of folic acid, can cause cancer and birth defects in humans and can cause kidney damage in dogs and cats. Aminopterin is not permitted for use in the United States.

The New York State Food Laboratory is part of the Federal Food Emergency Response Network (FERN) and as such, is capable of running a number of unique poison/toxin tests on food, including the test that identified Aminopterin.

Last month, a study conducted by archæologist Dr. Naomi Martisius and other researchers concluded Neanderthals living in Europe tens of thousands of years ago were more sophisticated than previously thought. The now-extinct species used to carefully select bones from a particular animal species to manufacture their bone tools, the research showed. The research was published on May 8 in Nature’s Scientific Reports journal.

Dr Martisius and her team used five bone tools discovered from Neanderthals’ sites in southwest France for this research. Four of these bone tools were found in a site called Abri Peyrony and the other one was from Pech-de-l’Azé I. These tools were just a few centimetres in size and were about 50 thousand years old, Dr Martisius told Wikinews. Microscopy analysis of these bone tools called lissoirs (smoothers) suggested Neanderthals used these tools for working animal skin to leathers.

The study stated the fauna of the sites were primarily medium-sized ungulates such as reindeer, in one layer nearly 90%. Despite the overabundance of medium-sized ungulates, Neanderthals used ribs of large bovids for making lissoirs. Dr Martisius told Wikinews this was likely due to the physical characteristics of the bovid ribs, which were “thicker” and “stronger” as compared to the “thin and flimsy ribs” of reindeers. In order to check the origins of the bone tools, the researchers used a technology called non-destructive Zooarchæology by Mass Spectrometry (ZooMS).

Instead of damaging the bone artefacts in order to discover its origins, the researchers collected collagen from the plastic containers in which these artefacts were kept. Collagen is a type of protein. These bone artefacts were kept in plastic containers: some were kept for about five years, some for just a few months. During this time, the collagen proteins from bone tools were stuck to the walls of its plastic containers. The collagen samples collected from the walls of the containers are broken into smaller molecules called peptides by using a chemical enzyme called trypsin.

After the trypsin has broken collagen fibres into peptides, it is analysed using a technology called Matrix-assisted laser desorption/ionization (MALDI) Time-of-Flight mass spectrometer (ToF MS). The assisting matrix is a coloured compound. The acidic peptide is combined with the matrix, vapourised, and peptides are released. Some of them are positively-charged particles which travel across a vacuum tube in an electric field. Depending on the weight of the peptides, these molecules reach the end of the vacuum tube at different instances of time, forming a spectrum. These graphs are like unique fingerprints of a species: they are different for different species of animals. Looking at the database of such graphs, taxonomic identifications of the collagen proteins came be made.

All four bone tools from Abri Peyrony gave positive results and showed that the bones were made from large bovids, even though reindeer were more abundant during that time. One of the advantages of using bovid ribs over reindeer’s thin ribs was the bovid ribs would be more resistant to breaking during flexion, Dr Martisius said.

Dr Martisius said such non-destructive ZooMS analysis was previously conducted, but for tools no older than a few centuries. She said such an analysis had never been previously conducted for artefacts so ancient.

Wikinews caught up with Dr Martisius to discuss this research in-depth.

Tim Donaghy, an ex-NBA referee, surrendered today for an appearance in a Brooklyn federal court. Law enforcement officials said that Donaghy allegedly placed his own bets, and also released confidential information to others, including referees’ schedules. Today, Donaghy pleaded guilty to ‘conspiracy to engage in wire fraud’ and ‘transmitting wagering information to other individuals’. These two charges could result in up to 25 years in jail.

Tim Frank, a NBA spokesman, told the Associated_Press the league was informed yesterday that Donaghy would plead today but was not given any further information.

Both John Lauro, Donaghy’s attorney, and federal prosecutors did not comment. But, NBA commissioner David Stern said a month ago that the ex-referee’s lawyer told the league Donaghy was contemplating a plea. The plea was made official early today.

Donaghy has been reportedly cooperating with prosecuting attorneys who together are building a case against other people to whom Donaghy may have provided inside information to. It has also been reported that Donaghy had a biased view against the Detroit Pistons, therefore making bets against them, and then calls against them as well

Donaghy today told the court that he had a gambling problem. However, he also said that he was receiving treatment for it.

The Associated Press reports that no other NBA officials or players are suspects in this case.

The FBI contacted the NBA on June 20, 2007 to talk about a referee who was allegedly gambling on games. The FBI and the NBA officially met on June 21. Donaghy resigned from his position July 9, after over ten years as a referee

A new report released by the New Zealand Ministry of Health titled “Suicide Trends” shows that the suicide rate in New Zealand has decreased 15% since its peak in the late 1990’s, but the attempted suicide rate is increasing.

There were 12 deaths per 100,000 people between 1983-’85. 16.7 deaths per 100,000 people between 1996-’98. And 14.2 deaths per 100,000 people between 2001-’03. But there were 73.1 attempted suicides per 100,000 people between 1995-’97 compared to 82.5 in 2002-’04.

Jim Anderton, Associate Health Minister, said “It provides some comfort to see the long-term trend still appears to be heading in the right direction, with a continued decline or levelling off of self-inflicted deaths but there is no room for complacency.”

The suicide report also shows that:

• The 25- to 34-year-old age group has the highest suicide rate
• Between 2000-’03 Maori has the highest suicide rate
• Men were less likely than woman to go to hospital for attempted suicide because more men died from suicide.

The New Zealand Government has put NZ$10.3 million towards direct suicide prevention. New Zealand News agencies are banned by law from reporting suicide deaths.

A suicide bomber killed 43 people in Iraq Sunday, injuring an estimated 40 more.

The attack occurred southwest of Baghdad and targeted members of a government-backed militia, Sons of Iraq, also known as the Sahwa, who were waiting to collect their pay. Early reports say the attacks killed at least three soldiers and injured an additional thirteen, while three accountants died and four more were wounded. It’s not yet clear who the remaining casualties are.

A survivor of the bombing said that “[t]here were more than 85 people lined up in three lines at the main gate of the military base to receive salaries when a person approached us. When one of the soldiers tried to stop him, he blew himself up.”

An Iraqi military official said that “[t]he suicide bomber blew himself up in the biggest group of Sahwa members. We generally let them enter the base in groups of 10 for them to get their salaries.”

A second suicide bombing took place in Western Iraq, when an attacker fired upon Sahwa militants in Al-Qa’im before blowing himself up, killing three people, with six more injured.

Credit for the attacks has not yet been claimed, but al-Qaeda is considered the probable culprit.

The Sahwa movement is a Sunni militia group that split from al-Qaeda in 2006, and with US support have been one of the groups fighting al-Qaeda. In recent months, members of the militia have said that they have come under attack from other militant groups, and support from the Iraqi government has been reduced.

London, England — As Paralympians ready for the Games which are set to open later this week, they have access to a world class fitness center inside the Paralympic Village which is designed to maximise their pre-Game preparations.

According to volunteers staffing the center, instead of being a single large room, as in Beijing, the building has numerous rooms. It, along with the adjacent Village Services Centre, is designed to be converted into a school after the games conclude. Rooms have been structured as a gym, an auditorium, and science laboratories.

Gym equipment is supplied by Technogym, an Italian firm that has supplied gym equipment for the Olympics since 2000. Equipment has been provided not just for for the Fitness Centre, but for gyms at all the Olympic venues. The newest equipment is oriented toward maximum flexibility, allowing athletes to exercise the particular muscles that they most require for their sport.

In addition to the equipment, the Fitness Centre also provides instructors trained in the use of the equipment, the likes of which athletes from many countries have never seen before. There are also a number of instructors available to provide motivational training.
