Japanese auto maker Toyota is to temporarily suspend sales of its luxury Lexus GX 460 SUV following an unfavorable verdict from Consumer Reports, which concluded “Don’t Buy: Safety Risk,” the first such warning in almost a decade.

After conducting its standard emergency handling tests on the 2010 version of the Lexus GX 460, Consumer Reports became concerned that the rear of the vehicle had a tendency to slide out, which in real life situations could lead to rollovers. However, the consumer organisation is also unaware of any such incidents with the 5000 GX 460s sold since its launch three months ago.

Already embattled with ongoing safety issues with its vehicles, Toyota has been quick to act, though it did claim that the car was safe to drive and that it had passed internal safety standards. According to Toyota, “Lexus’ extensive vehicle testing provides a good indication of how our vehicles perform and we are confident that the GX meets our high safety standards.”

On Wednesday, astronomers at the University of Cambridge in England announced the discovery of a dwarf star, known as EBLM J0555-57Ab, which is slightly bigger than Saturn and smaller than Jupiter. It was found using data from an array of automated telescopes called the Wide Angle Search for Planets (WASP). The study was published in the journal Astronomy & Astrophysics.

The star belongs to the Milky Way galaxy and is approximately 600 light years away from Earth. Its mean radius is about 80 percent the size of the largest planet in the Solar System, Jupiter, but despite its small size it is very dense. Its mass is almost 85±4 times the gas giant, the study said. The star’s surface gravitational pull is about eleven times stronger than the Sun’s — 300 times the strength by which the Earth attracts matter. It is part of a binary star system, meaning it moves around the galaxy with another star, both orbiting around the same central point. However, it stays so close to its companion star, that it takes about 7.8 days to orbit around the pair’s shared centre. The distance between the two stars is less than between Mercury and the Sun, and about eight percent of an astronomical unit, in stark contrast to the 100–1000 astronomical units that typically separates two stars in such a system.

It was discovered by the method called “astronomical transit”. This method is used to discover planets or satellites, and the astronomers initially thought it was merely an exoplanet. During a planet’s revolution, when it crosses its parent star, there is a dip in the brightness of the light coming from the parent star. The companion of this dwarf is the size of the Sun, and it is brighter than the dwarf, making the discovery more difficult. “Indeed, until we measured the mass it looked just like a transiting planet”, Amaury Triaud, co-author of the paper, told Popular Mechanics. With a brightness 2000 to 3000 times fainter than the Sun, it was the mass that indicated it was actually a dim star.

According to lead author of the study, Alexander von Boetticher, their “discovery reveals how small stars can be.” He added, “Had this star formed with only a slightly lower mass, the fusion reaction of hydrogen in its core could not be sustained, and the star would instead have transformed into a brown dwarf”. A brown dwarf converts hydrogen to deuterium, a hydrogen isotope, rather than helium, which is the usual result of such a process from most stars including the Sun.

The tiny star’s temperature is lesser than most known gas giant exoplanets. “That star likely represents the smallest natural fusion reactor that we know of[…] We’re trying to replicate fusion on Earth in labs, but that’s basically as small as it gets in nature”, Triaud told CBC News. The size of the star makes it difficult to study, but the brightness of its companion star also makes it more challenging. “It’s like trying to look at a candle beside a lighthouse,” Triaud said.

Goodluck Jonathan, vice-president of Nigeria, has become the country’s acting president after president Umaru Yar’Adua travelled to Saudi Arabia last November to receive medical treatment for a heart condition.

In a televised address, Jonathan commented, “I am fully aware of the responsibilities reposed in me, and I want to reassure all Nigerians that this is a sacred trust, which I shall discharge to my fullest abilities. […] The circumstances — in which I find myself assuming office today as acting president of our country — are uncommon, sober and reflective.”

He added, “[m]ore than ever therefore, I urge all Nigerians as a people who have faith in God to pray fervently for the full recovery of our dear president, and his early return”.Yesterday saw both houses of the Nigerian National Assembly approve a motion for Jonathan to become president until Yar’Adua is able to return. Under the country’s constitution, executive power can be transferred when parliament is formally informed by the president that he is absent. Yar’Adua apparently had not done so; however, senate leader David Mark said that Yar’Auda’s comments in an interview with the BBC last month were sufficient notice.

Some political analysts, however, have indicated the assembly’s move might not be legally binding, and could face a court challenge.

Heavy snow has caused disruption in the United Kingdom with airports and schools closed and delays on the road network.

Snowfall was highest near Worcester with 9cms of snow falling. The snow has caused hundreds of school closures and major disruption to airports with Birmingham, London Gatwick and City, Bristol and Cardiff runways closing although these have now re-opened. However the runways at Luton and Stanstead remain closed due to the bad weather.

The road network has also been affected with some snow settling and accidents occurring causing major congestion in some areas, althought gritting by the Highways Agency and local authorities has limited the effect on trunk roads and motorways.

Schools were closed in Birmingham, Solihull and Dudley, while some remained open in Gloucestershire, Herefordshire, East Anglia and Wales, Shropshire, Staffordshire and Cheshire.

Drivers are being warned that driving conditions will continue to be adverse and are being advised only to travel if absolutely necessary.

Train services by Midland Mainline and Virgin as well as the London Underground are affected, with delays, reduced services and cancellations.

The overall economic effect of the snow is predicted to cost the British economy approximately £400 million due to loss of work hours.

There has also been loss of power in some areas of Wales including Abergaveny, Llandeilo and Blaenporth.

The snow fall is expected to continue into the evening but may turn to sleet in some areas. Also cold temperature tonight will mean that there is a high chance of ice forming on the road network. Up to 15 cm of snow is expected through the day in some hilly areas but wetter and milder weather is expected over the weekend.

Reports say that a team of treasure hunters from the United States has recovered over 500 million U.S. dollars (£253m) worth of gold and silver coins off the coast of Cornwall, United Kingdom in what is being called the biggest treasure find ever, but the exact location of the treasure has not been named because of security and legal concerns. The operation is codenamed the Black Swan Project.

Odyssey Marine Exploration made the discovery and the treasure is believed to be from a 17th century shipwreck located some 40 miles off the Cornish coast. There have reportedly been hundreds of thousands of the silver coins and at least 200 gold coins found in the wreckage, some in “near mint condition.” All the coins are being examined in the U.S. by experts.

“The gold coins are almost all dazzling mint state specimens,” said one of the founders of Odyssey Marine Exploration, Greg Stemm.

The reports came out when Doctor Lane Brunner, who is located in the U.S. and is an expert on coins, said that the team had to report the discovery to a judge in the fall of 2006 before the finds could be salvaged.

“They told a judge at that point that they had found the wreck of a seventeenth-century merchant ship in the Atlantic Ocean, just outside the English Channel – about 40 miles off Land’s End. So all we can do is add two and two together. It would seem logical given the timing and everything that could be the site,” said Brunner.

Reports suggest that the shipwreck is that of the Merchant Royal which is said to have sunk in 1641 near the Isles of Scilly.

“We have treated this site with kid gloves and the archaeological work done by our team out there is unsurpassed. We are thoroughly documenting and recording the site, which we believe will have immense historical significance,” added Stemm.

The Service Employees International Union, a trade union in the United States and Canada, was trying to unionize 8,300 workers in nine different Ohio hospitals through elections that were scheduled for this Wednesday and Friday. But then organizers from a second union, the California Nurses Association, visited the hospitals to encourage the workers to vote not to join the S.E.I.U. These actions led to the service employees union on Tuesday asking to postpone the vote by workers at the nine hospitals, all which are a part of the Catholic Healthcare Partners system.

Andy Stern, the service president is quoted as saying, “nothing more than a flimsy cover for out-and-out union busting that we normally see from employers, not organizations that claim to care about workers.”

The California Nurses Association, said it dispatched organizers to Ohio because in its view the unionization efforts were part of a “sweetheart deal”.

Rose Ann DeMoro, executive director of the nurses association, condemned this agreement. She called it “a rigged scam” in which the service union would bargain without care if they won the vote.

“This was a top-down deal between an employer and a hand-picked union,” Ms. DeMoro said. “There was a gag order on everyone, and as a result this was a banana republic election.”

“As for the future,” DeMoro said, “no election is planned.” She said that delaying the election was “a significant victory for employee rights.”

Dave Regan, president of a service employees’ local representing 35,000 health care workers in Ohio, West Virginia and Kentucky, called the nurses union’s conduct as, “Their conduct is indistinguishable from that of the most vicious anti-union employers,” Mr. Regan said. “It violates every principle of unionism. Real people are worse off today as a result of their behavior.”

Orest Holubec, spokesman for Catholic Healthcare, said the system’s hospital in Lima had obtained a restraining order to bar the California nurses from entering restricted patient-care areas and aggressive leafletting outside hospitals. “They were doing exactly the kind of things we were trying to avoid,” Mr. Holubec said. “They poisoned the well to the degree that we didn’t have the conditions that we tried to establish for a pressure-free environment.”
