Aminopyralid, which is found in several Dow products, the most popular being Forefront, a herbicide, is not licensed to be used on food crops and carries a label warning farmers using it not to sell manure that might contain residue to gardeners. The Pesticides Safety Directorate, which has issued a regulatory update on the weedkiller, is taking samples from affected plants for testing.

Problems with the herbicide emerged late last year, when some commercial potato growers reported damaged crops. In response, Dow launched a campaign within the agriculture industry to ensure that farmers were aware of how the products should be used. Nevertheless, the herbicide has now entered the food chain. Those affected are demanding an investigation and a ban on the product. They say they have been given no definitive answer as to whether other produce on their gardens and allotments is safe to eat.

It appears that the contamination came from grass treated 12 months ago. Experts say the grass was probably made into silage, then fed to cattle during the winter months. The herbicide remained present in the silage, passed through the animal and into manure that was later sold. Horses fed on hay that had been treated could also be a channel.

By the time Joseph Needham died in 1995, he had published 17 volumes of his Science and Civilisation in China series, including several that he wrote entirely on his own.

The Chinese began printing 600 years before Johannes Gutenberg introduced the technique in Germany. They built the first chain drive 700 years before the Europeans. And they made use of a magnetic compass at least a century before the first reference to it appeared elsewhere. So why, in the middle of the 15th century, did this advanced civilisation suddenly cease its spectacular progress?
…
Needham never fully worked out why China’s inventiveness dried up. Other academics have made their own suggestions: the stultifying pursuit of bureaucratic rank in the Middle Kingdom and the absence of a mercantile class to foster competition and self-improvement; the sheer size of China compared with the smaller states of Europe whose fierce rivalries fostered technological competition; its totalitarianism.

Today, wheat provides about 20 percent of the food calories for the world’s people. The world wheat harvest now stands at about 600 million metric tons.

In the last decade, global wheat production has not kept pace with rising population, or the increasing per capita demand for wheat products in newly industrializing countries. At the same time, international support for wheat research has declined significantly. And as a consequence, in 2007-08, world wheat stocks (as a percentage of demand) dropped to their lowest level since 1947-48. And prices have steadily climbed to the highest level in 25 years.

The new strains of stem rust, called Ug99 because they were discovered in Uganda in 1999, are much more dangerous than those that, 50 years ago, destroyed as much as 20 percent of the American wheat crop. Today’s lush, high-yielding wheat fields on vast irrigated tracts are ideal environments for the fungus to multiply, so the potential for crop loss is greater than ever.

If publicly financed international researchers move together aggressively and systematically, high-yielding replacement wheat varieties can be developed and made available to farmers before stem rust disease becomes a global epidemic.

The Bush administration was initially quick to grasp Ug99’s threat to American wheat production. In 2005, Mike Johanns, then secretary of agriculture, instructed the federal agriculture research service to take the lead in developing an international strategy to deal with stem rust. In 2006, the Agency for International Development mobilized emergency financing to help African and Asian countries accelerate needed wheat research.

But more recently, the administration has begun reversing direction. The State Department is recommending ending American support for the international agricultural research centers that helped start the Green Revolution, including all money for wheat research. And significant financial cuts have been proposed for important research centers, including the Department of Agriculture’s essential rust research laboratory in St. Paul.

This shocking short-sightedness goes against the interests not only of American wheat farmers and consumers but of all humanity. It is tantamount to the United States abandoning its pledge to help halve world hunger by 2015.

The project will pour $1 billion into utility-scale photovoltaic solar farms that will directly feed power into a country’s electrical grid. The installations will range from fewer than 2 MW to up to 50 MW, while a single farm could cover hundreds and hundreds of acres.

They’ll be installed in Europe. In Asia. And maybe even in America too, one day. Why not now? Because AES wants to sow its solar seeds in only those countries that offer the most “attractive tariffs.” That eliminates the US from the list of potentials, immediately. And it gives countries like Germany, Spain, Italy and South Korea the clear advantage. They all have can’t-beat national incentives for solar developers.

It’s one of the sad facts of Washington’s incoherent clean energy policy these days. How can a country lure in clean energy projects when there are far more appealing offers elsewhere?

Employment in Germany’s engineering industry is expanding at its fastest rate in 40 years, highlighting the strength of Europe’s largest economy as global financial storms intensify.

Jobs in the sector – the backbone of Germany’s manufacturing industry – rose by 27,000 in January, the highest monthly increase since the 1960s, according to figures published on Tuesday by Gesamtmetall, the engineering employers’ federation. Some companies reported losing production because they could not fill vacancies quickly enough.
…
He said that about one in eight of the approximately 6,100 engineering companies were having difficulties in recruiting qualified engineers and mechanics, with this in some cases leading to production cutbacks. “Many companies misjudged how quickly the economy would recover and therefore failed to take on sufficient trainees,” Mr Vajna said. There also remained a shortage of engineering graduates, he added.

University of Michigan researchers are investigating a radical new design for cargo ships that would eliminate ballast tanks, the water-filled compartments that enable non-native creatures to sneak into the Great Lakes from overseas. At least 185 non-native aquatic species have been identified in the Great Lakes, and ballast water is blamed for the introduction of most—including the notorious zebra and quagga mussels and two species of gobies.

This week, the U.S. Saint Lawrence Seaway Development Corp. will implement new rules designed to reduce Great Lakes invaders. Ships will be required to flush ballast tanks with salt water before entering the Seaway, a practice corporation officials describe as an interim measure, not a final solution.
…
Instead of hauling potentially contaminated water across the ocean, then dumping it in a Great Lakes port, a ballast-free ship would create a constant flow of local seawater through a network of large pipes, called trunks, that runs from the bow to the stern, below the waterline.

“In some ways, it’s more like a submarine than a surface ship,” Parsons said. “We’re opening part of the hull to the sea, creating a very slow flow through the trunks from bow to stern.

Engineering professors Ray LaPierre, who is working with Cleanfield on solar cells made from a dense turf of nanowires, and Adrian Kitai, who co-founded Flexible Solar to make bendable solar panels that are less costly to manufacture, are showing how skills typically prized in the telecom sector can be repurposed to build better solar technologies.

Similar efforts are also being made at the University of Toronto’s Institute for Optical Sciences, where a new spin-off called The Solar Venture aims to improve the economics of solar. “Ontario was a global leader in telecom, but now that has slowed down,” says Rafael Kleiman, professor of engineering physics and director of McMaster’s Centre for Emerging Device Technologies. “All the people, all this research (in telecom), is finding a new home. I really believe Ontario can make itself a global hub in solar photovoltaic technologies.”

A solar cell is just a big specialized chip, so everything we’ve learned about making chips applies,” Paul Saffo, an engineering professor at Stanford University, recently told the New York Times. There’s a reason why California’s Silicon Valley, the headquarters of data-networking king Cisco Systems and semiconductor goliath Intel, is positioning itself as Solar Valley.

When i left India for post-graduate studies in 1975, there were perhaps 600 million people in India, and we had five IITs (Indian Institutes of Technology). Today, we are nearly double that population, and we have seven IITs, one of which has essentially involved the relabelling of an existing Regional Engineering College. To keep up with demand - and the needs of the marketplace - shouldn’t we have had 20 IITs by now of the same standard as the original five? Or even 30?

India is entering the global employment marketplace with a self-imposed handicap of which we are just beginning to become conscious - an acute shortage of quality institutions of higher education. For far too long we have been complacent about the fact that we had produced, since the 1960s, the world’s second largest pool of trained scientists and engineers.
…
Whereas countries in the Middle East, and China itself, are going out of their way to woo foreign universities to set up campuses in their countries, India turns away the many academic suitors who have come calling in recent years. Harvard and Yale would both be willing to open branches in India to offer quality education to Indian students, but have been told to stay away. Those Indians who choose to study abroad easily get scholarships to do so - currently 80,000 of them are in the United States alone.

It sounds almost too good to be true: a cheap and simple drug that kills almost all cancers by switching off their “immortality”. The drug, dichloroacetate (DCA), has already been used for years to treat rare metabolic disorders and so is known to be relatively safe. It also has no patent, meaning it could be manufactured for a fraction of the cost of newly developed drugs.

Evangelos Michelakis of the University of Alberta in Edmonton, Canada, and his colleagues tested DCA on human cells cultured outside the body and found that it killed lung, breast and brain cancer cells, but not healthy cells. Tumours in rats deliberately infected with human cancer also shrank drastically when they were fed DCA-laced water for several weeks.

DCA attacks a unique feature of cancer cells: the fact that they make their energy throughout the main body of the cell, rather than in distinct organelles called mitochondria. This process, called glycolysis, is inefficient and uses up vast amounts of sugar.

Until now it had been assumed that cancer cells used glycolysis because their mitochondria were irreparably damaged. However, Michelakis’s experiments prove this is not the case, because DCA reawakened the mitochondria in cancer cells. The cells then withered and died

Foreign-born engineering, science, and math students in the United States should be automatically granted legal residency when they get a job in this country, said California Congresswoman Zoe Lofgren.

Lofgren, a Democrat, spoke to an audience Friday at the Joint Venture: Silicon Valley conference about threats to innovation in the area. She said that about 56 percent of the Ph.D. candidates at the finest schools in the United States are immigrants, and because of the government’s current immigration policy, many of those people leave the country.

Engineering interests historically haven’t been at the forefront of the political debate, at least not compared with those of, say, farming, law or health care. But given the importance of the technological advances that engineers help effect and the need to maintain our competitive edge in a rapidly changing global environment, that situation needs to change, and fast.

Then came word of the $25 billion being handed to farmers in yet another subsidy, loudly denounced by some as welfare for the wealthy. I’m not going to get into the right or wrong of the subsidies–but I am amazed at the ability of agribusiness to get them at all. It shows the power of the farm lobby. Ditto for pharmaceuticals, HMOs, lawyers, “big oil” and so on. It underscores the relative political weakness of the engineering community.

When China’s leaders meet with Hu each week in Beijing’s government district, Zhongnanhai, they could spend hours discussing cables, switches, tool-making machines and control devices. That’s because every one of them has a degree in engineering. The president himself, the son of a tea merchant from Jiangsu Province, trained to build hydroelectric power stations, while the others hold degrees in electrical engineering, metallurgy and geology.

Promising technologies already exist that could be developed to deliver renewable energy cheaper than coal. We think the time is ripe to build rapidly on the tremendous work on renewable energy. For example, I believe that solar thermal technology provides a very plausible path to generating cheaper electricity. By combining talented technologists, great partners and large investments, we have an opportunity to quickly push this technology forward. Our goal is to build 1 gigawatt of renewable energy capacity that is cheaper than coal. We are optimistic that this can be done within years, not decades. If we succeed, it would likely provide a path to replacing a substantial portion of the world’s electricity needs with renewable energy sources.

To lead this effort, we’re looking for a world-class team. We need creative and motivated entrepreneurs and technologists with expertise in a broad range of areas, including materials science, physics, chemistry, mechanical engineering, electrical engineering, land acquisition and management, power transmission and substations, construction, and regulatory issues.
