The body’s immune system is less effective at quashing disease than it could be – but if it were better the immune system might do more harm than good, according to new research by Michael Deem and colleagues of Rice University in Houston.

The immune system has apparently evolved to be mildly inefficient so that it achieves a balance between quick response to disease and decreased probability of autoimmune disease, a condition in which the immune system attacks healthy tissue.

The authors drew their conclusions from a model of the dynamics of antibody evolution. Their simulations show that while there are mechanisms that would allow the immune system to develop antibodies that respond faster and more strongly against invading pathogens, those mechanisms would also create antibodies that are likely to attack the body’s own healthy cells. The model also bolsters controversial suggestions that chronic infections could lead the immune system awry, ultimately resulting in rheumatoid arthritis or other autoimmune ailments.

The study will be detailed in a forthcoming issue of the journal Physical Review Letters.

Israeli media is reporting that Prime Minister Ariel Sharon opened his eyes for the first time since he suffered a major stroke on January 4, 2006.

However, hospital officials said the reports were generated by the Sharon family’s “impression of eyelid movement, whose medical significance is unclear.”

“He was listening to a tape of his grandson and you could see tears in his eyes for a matter of seconds before he closed them again,” a doctor treating Sharon told AFP news agency on condition of anonymity.

Army Radio, citing unidentified close associates of Sharon, say the Prime Minister could “recognize people around him.”

However, hospital officials state that it is “too early to tell whether the development represented a significant improvement or was just a temporary reflex.”

Sharon had undergone a tracheotomy on Sunday to help with his breathing and to help prevent infection from his respirator tube.

Australian industral relations reform legislationmade up of 700 pages of bill legislation and 500 additional pages of explanatory memoranda was introduced into the Federal House of Representatives November 2, where the Opposition heatedly attempted to address their perceived problem of the Government’s lack of discussion and debate over the matter.

The first reading of the bill was the first order of the day, and when Kevin Andrews tried to do so, Opposition member Stephen Smith, responsible for workplace relations, immediately moved a motion deferring the bills to the House of Representatives Standing Committee on Employment, Workplace Relations and Workforce Participation. The Leader of the House, Tony Abbott moved that Smith and the necessary supporter — viz., Julia Gillard — be not further heard (cloture). The Government’s majority in the House ensured that this would happen. However, Opposition members attempted to use House standing orders necessitating that copies of the bill to be “available to Members”, with argument arising whether “available to Members” meant all members or simply whether some copies should be available; this ended up in a dissent motion moved against the Speaker of the House.

Later, in a heated Question Time, where six members of the Opposition, (Kelly Hoare, Julia Irwin, Anthony Albanese, Bernard Ripoll, Catherine King, and Gavan O’Connor), were removed from the Chamber during Question Time under standing orders for disruption — Jill Hall quipped that she was “glad to be still here to ask [her] question” — nearly all questions to the Government put by the Opposition, the subsequent time for matters of public importance, and some members in the adjournment debate, was all on the topic of the industrial relations reform.

To implement and fund the legislation, the government will “spend an additional $486million on industrial relations changes over four years, or $121million a year. This spending would be in addition to the present annual budget of $86million.” said an unnamed government source for The Australian.

The government will need to use its corporation powers to remove the powers from the states to alter the award conditions and other employee employer related conditions. But the New South Wales premier Morris Iemma has received legal advice that the legislation maybe unconstitutional, the reason being its being used to end the role of the states and territories Australian States in the industrial relations system. “It is our view that the Commonwealth is misusing this law to achieve exactly what it was designed to prevent”, Iemma said. Mr Iemma will be challenging the changes in the high court with Peter Beattie Premier of Queensland supporting his challenge in the High Court.

The Cambridge city council adopted a resolution on April 4 to request that the US Department of Environmental Protection (DEP) “take explicit account” of the activities of local construction firm W. R. Grace, which has previously contaminated an industrial area near the Alewife train station with asbestos. The council cited Grace’s “extraordinarily extensive and well-documented history of contaminating sites and concealing the contamination” as the reason for its request.

The resolution was a reaction to a Response Action Outcome Statement and Risk Characterization (RAO) that W. R. Grace filed with the DEP. The Cambridge Chronicle recently took the filing as evidence that “the state seems poised to stop watching over” the contaminated site.

In February, W.R. Grace was indicted by a federal grand jury for contamination as a product of vermiculite mining operations in Libby, Montana, USA. The company was also charged with “concealing information about the health affects [sic] of its asbestos mining operations.”

Toyota announced on Friday that it will recall around 17,000 Lexus vehicles in response to risks of the fuel tank in the cars leaking after a collision.

The Lexus HS 250h model was subjected to the recall following a US National Highway Traffic Safety Administration (NHTSA) investigation. Despite previously passing Toyota safety inspections, the conclusions of an NHTSA sub-contracted investigator were that; when the vehicles in question collided with an object at more than fifty-miles-per hour, more than 142 grams of fuel, the maximum allowed by US law, leaked from the crashed car.

According to Toyota, further tests did not show any additional failure of the fuel tank.

In response to the findings, Toyota issued a recall of all affected vehicles, since the company had no solution immediately available. The recall includes 13,000 cars already sold, as well as another 4,000 still at dealerships.

Toyota says it plans to conduct further tests to determine the cause of the leak. A Toyota spokesman, Brian Lyons, said that the company was “still working to determine what the root cause of the condition is.” It’s still unclear when exactly the recall will take place, or when dealerships will be allowed to sell this model again. Lyons said that Toyota is “working feverishly to get this resolved as soon as possible.”

Toyota isn’t aware of any accidents stemming from the leaking fuel tank in the affected vehicles, first introduced in the summer of 2009.

Ford Motor Company said on Tuesday that its sales in the United States rose 43% in February compared to the same period last year, as the automaker outsold rivals Toyota and General Motors.

Ford said that total sales improved to 142,285 units, compared to 141,951 units sold by GM. Additionally, Ford said that its share of the total US car market rose to 17%, up from 14% a year ago. The increase was better than analysts had predicted, and Ford’s stock rose to a five-year high in morning trading, before declining later in the day. Ford’s sales were significantly influenced by a 74% increase in fleet sales to businesses. Rental car agencies alone accounted for around 30,000 units sold. Sales to retail consumers increased only 28%.

The increases were led by sales of two sedans, the Fusion and Taurus, which rose 166.5 and 93.3% respectively, although sales of other models such as SUVs and pickup trucks also increased. Both models were significantly redesigned last year, and analysts said that improved quality from such cars were driving the increases.

Other companies also reported February sales today, nearly all reporting sales gains as well, although none as large as those of Ford. Toyota was the sole exception to the sales gains, as their sales declined 8.7%, as the company was faced with a global recall during the month that led to a temporary stoppage of production for some models.

“The strength of our new products … are resonating with customers,” said Ken Czubay, Ford’s vice president of sales and marketing. However, he believed that traditional Toyota customers were not buying rival autos, but rather awaiting the results from the recalls.
