In a glut market for potatoes in Europe this is what happens. From $600 euros a ton in 2023 to zero for the price of potatoes in the spot market  in Belgium in 2026. Europe has asurplus f 5 million metric tons of potatoes of the kind used to make french fries. In the past it could be shipped as exports to the US. Not anymore US has tariffs to protect US farmers in Idaho and other states. An Idaho potato maker financed Micron in the 1960's which now is a major chip maker nearing valuation of 1 trillion dollars in the stock markets. You have this situation where a thousand tons of potatoes stacked 15 feet high in a Belgian warehouse is dumped back into the ground. The Belgian farmer D'haeyere took a loss of $160,000 euros on soil, seedlings, fertilizer and labor. He is planting only 17 acres for 2027 down from 170 acres he planted  this year. Belgium is the largest exporter of french fries in the world.

What would making a new vaccine for the Omicron South African variant look like? How long will it take and how does it happen? Adam Whipple, Science Editor of The Times, looks at the process in the 100 days it would take Pfizer to do this in this excellent article that anticipates and answers readers questions. New mutations are shown to be taking place in the virus, it is shown here that UK and world capabilities have also increased to tackle the problem in the last 18 months.

South Africa feels a sense of relief as omicron cases follow a pattern of very steep upward increase, followed by a short period of a month, and then a very steep decrease. Cases in South Africa with a population of 60 million, about the size of Britain, dropped from 27,000 at the peak to about 15,000 on December 21, 2021. The area around Johannesburg was hardest hit. The median age is 27 years in South Africa, 40 in UK and 43 in Italy. With younger populations in India and parts of Asia South African population demographic is closer to India than it is to Europe where populations are much older. Scientists do not want to extrapolate from the South African experience with Omicron for this reason. Immunity from vaccination and prior infection could be contributory causes to the less severity of omicron say NCID scientists. "In South Africa this is the epidemiology. Omicron is behaving in a way that is less severe," says Dr. Cheryl Cohen, of the National Institute for Communicable Diseases (NCID). "Compellingly together our data really suggest a positive story of a reduced severity of omicron compared to other variants," he said at a conference with other scientists on Wednesday, Dec. 22.  ...

New York Governor Kathy Hochul said Friday that the state recorded 21,027 new covid cases surpassing the previous record of 19,942 set in January. Of 263,000 tested about 8% were positive- health officials say positivity rate doubled over 3 day period through Sunday.

William Lee, vp science at Helix, population-genomics company that does surveillance and testing, says Omicron will likely be the dominant strain in the US within a week. He says it is growing so much faster as a proportion of cases, than any previous variants.

China's efforts to build its own core technologies in chip production leads to a ban on American manufacturer Micron for supplying China's chip needs. This allows Chinese companies to fill the need as China pursues its own Made in China model similar to America's Made in America model that president Biden is taking up to catch up with Taiwan. The title is a misnomer as there is no clash as such with the US when countries are developing their own safer supply chains as the US is doing and working with its European allies on this. In fact the competition is with Taiwan, in an effort to correct a mistaken decision for the US under the pressure of laissez faire advocates in the US to not let the federal government support American chip makers that over two decades has created this huge gap with Taiwan. Laissez faire means to leave alone, which came at the wrong time when competing nations including Taiwan and South Korea were supporting their chipmakers aggressively and covertly and presenting their costs as something the US could not compete with. US president Biden has every intention to correct his and the Biden CHIPS Act is only the first step to do this.  ...

The third or booster dose of vaccine is needed to take out the Omicron variant. The UK Health Security Agency analyzed data from 581 Omicron cases and thousands of Delta cases to calculate how effective vaccines such as Pfizer and Astra Zeneca were against the Omicron variant. This early analysis shows a third booster dose prevents around 75% of people from getting any coronavirus symptoms. The double dose of the vaccine however provides good protection against severe coronavirus that needed hospital treatment says the UK Health Security Agency. Of equal concern is the rate of spread of the Omicron variant. Here this BBC report shows graphs of UK National Health Security Agency which show the rate of spread is rapid with cases doubling every 2-3 days. For the UK which on December 10 had about 1265 cases this means says this BBC report that the number of Omicron cases could be well above 100,000 in the UK by the end of December. The BBC graph shows the curve for Omicron cases moving in a close to vertical direction upwards. Reports say the experience in South Africa where the Omicron variant was first detected is similar in pattern causing rapid spread. ...
