The increase reported Tuesday by the Federal Reserve Bank of Kansas City, Mo., reflects current low interest rates and a healthy farm economy. But the higher land values will make farming more expensive.

“It makes it difficult for early farmers or farmers who want to expand their operation,” Nebraska Farm Bureau President Keith Olsen said. “The other big concern is that as ag values go up, property taxes are going up.”

Land values increased despite widespread flooding and drought that many farmers in the region struggled with this year. Several hundred thousand acres of farmland along the Missouri River spent much of the summer under water because of flooding, and southern Plains states have been battling severe drought.

But as long as the weather in their area cooperated, farmers did well. Corn prices hit a record high of $7.99 a bushel in June because thin supplies prompted fears of a shortage. Wheat prices also have been high, and some farmers have used the extra income to buy land.

“If you had the moisture to raise a crop, it’s going to be a good year,” said Ron Meyer, who farms near Superior in southeast Nebraska.

She said about 250 US Marines would arrive next year, eventually being built up to 2,500 personnel.

A team of engineers has created an electrode for lithium-ion batteries — rechargeable batteries such as those found in cellphones and iPods — that allows the batteries to hold a charge up to 10 times greater than current technology. Batteries with the new electrode also can charge 10 times faster than current batteries.

The researchers combined two chemical engineering approaches to address two major battery limitations — energy capacity and charge rate — in one fell swoop. In addition to better batteries for cellphones and iPods, the technology could pave the way for more efficient, smaller batteries for electric cars.

The technology could be seen in the marketplace in the next three to five years, the researchers said.

International prices for some light rare earths, like cerium and lanthanum, used in industries like the polishing of flat-screen televisions and oil refining, respectively, have fallen by two-thirds since August and are still dropping. Prices have declined almost as quickly for highly magnetic rare earths, like neodymium, needed for products like smartphones, computers and large wind turbines.

Big companies in the United States, Europe and Japan have been moving operations to China, drawing down inventories, switching to alternative materials or even curtailing production to avoid paying extremely high prices that prevailed outside China over the summer, executives said at an annual conference in Hong Kong on Wednesday.

As demand for rare earths has wilted outside China, speculators have been dumping inventories, feeding the downward plunge. Cerium peaked at $170 per kilogram, or $77 a pound, in August but now sells for $45 to $60 per kilogram.

The top five executives at Fannie Mae received $33.3 million in 2009 and 2010, while the top five at Freddie Mac received $28.1 million. And each company has set pay targets of as much as $17 million for its top managers for 2011.

That’s a total of $95.4 million, which will essentially be coming from taxpayers, who have been keeping the mortgage finance giants alive with regular quarterly cash infusions since the Federal Home Finance Agency (FHFA) took control of the companies in September 2008.

A team of international researchers said food production would likely be “severely impaired” by the elevated levels of caesium found in soil samples across eastern Fukushima in the wake of meltdowns at the tsunami-hit plant.

The study, published in the Proceedings of the National Academy of Sciences journal, suggests farming in neighbouring areas may also suffer because of radiation, although levels discovered there were within legal limits.

“Fukushima prefecture as a whole is highly contaminated,” especially to the northwest of the nuclear power plant, the researchers said.

Taxi drivers in the university town have been told that they need to install the £460 devices by 2015 or face having their licenses revoked. The microphones, accompanied by CCTV cameras, will activate once the ignition in the car is turned on and will remain recording for 30 minutes after the engine is turned off.

The council says the recording equipment is necessary to protect drivers and passengers as well as deal with any disputes over fares. Recorded information would only be accessible to the police or council officials.

But privacy campaigners say the plans represent a significant “ramping up” of surveillance culture in Britain and may well be in breach of Government guidelines.

That’s exactly the point, according to the Darpa-funded researchers behind a collaborative effort underway at MIT and the Florida Institute of Human and Machine Cognition (IHMC). Only one year into a four-year research contract, the team is showing off stunning results that are expected to produce the fastest, most agile ‘bot ever. He’s called FastRunner, and he’ll zip along at 10 times the speed of a standard mobile robot, which clocks a mere 3 miles per hour.

“We’re using principles found in biology to build efficiency and speed right into the robot,” Johnny Godowski, a research associate at IHMC, tells Danger Room. “And we’re confident that this will open up the possibility for humanoid robots that are useful in all sorts of situations — military for one, but also fire rescues or natural disasters, for example.”

While Iranian officials insist the explosion at the Bid Ganeh base was accidental, caused by the movement of ammunition, claims from anonymous western and Israeli officials that Saturday’s blast was a covert Israeli operation have gained momentum.

Leading Israeli daily Yediot Ahronot picked up a post by US blogger Richard Silverstein claiming the Mossad had teamed up with Iranian militant group Mujahideen e-Khalq (MEK) to execute the alleged attack. MEK denies involvement in the attack.

Leftwing broadsheet Ha’aretz also led with reports that a western intelligence source quoted in Time magazine had claimed the Mossad carried out the attack in an attempt to stall Iran’s development of a nuclear weapon. The official is said to have warned: “There are more bullets in the magazine.”

The blast at the base, which is reported to have been a storage facility for long-range missiles, was so powerful that it was said to have been felt 30 miles away in the capital, Tehran.

Among those killed was Major General Hassan Moghaddam, the Revolutionary Guard Commander charged with “ensuring self-sufficiency” in armaments, and described by Iranian media as a pioneer in Iranian missile development.

Israel’s defence minister, Ehud Barak, responded to news of Moghaddam’s death by saying: “May there be more like it.”
