Increased demand nationwide due to extremely cold weather is limiting supplies available for drying crops.While extremely frustrating for these who have seen corn harvest stifled, the good news is more-seasonable temperatures are expected to return to most of the country. This, in turn, should lower demand for propane and make more available to the market; but it will take some time.A BAD COMBINATIONDTN Oil Markets Reporter Alton Wallace said, “A bad combination of crop drying and extremely low temperatures over a good portion of the nation in recent weeks has caused propane demand to outstrip supply.” DTN wrote about this last week as these issues first emerged. (See https://www.dtnpf.com/…)The lack of propane supplies for crop drying is more evident the farther north you move in the Midwest. This region faced a double whammy with crops that were wet and locations farther away from the pipelines that supply the product.“For those in more northern areas, they are at the end of the line and it is more expensive to get the product to these places,” Wallace said.PROPANE PRICES LOWER THAN LAST YEARThe increase in demand has not affected the price of propane, at least not yet, although some local areas have seen increases. The propane price at the Conway, Kansas, Hub that stores approximately one-third of the nation’s propane, finished Thursday at 52.75 cents per gallon, which is actually lower than a year earlier.Wallace said he believes the market is looking ahead to the coming weeks when temperatures across the Midwest are forecast to return to more-seasonable levels. This will lessen demand at terminals and, hopefully, there will be more supply available for farmers drying crops, he said.DTN Senior Ag Meteorologist Bryce Anderson said this November had a historic cold snap — the coldest in a century in many areas east of the Rockies. In many instances, temperatures were 20 to 30 degrees lower than normal.“What made this one stand out is the fact that this Artic cold plummeted all the way south to the Gulf Coast with its harsh impact,” Anderson said.Anderson said the temperature pattern shows a more moderate trend through the Thanksgiving Day holiday. Seasonal levels will seem almost warm after this cold wave, he added.GRAIN DRYERS WAITMatt Undlin, a farmer from Lansford, North Dakota, told DTN his corn harvest could be stalled for the rest of November due to lack of propane to dry down his crop. His retailer said they were 10 semi-loads behind and priority will be given to hospitals, churches, schools, businesses and residences. If any propane is left, it will be made available for crop drying, he said.In addition, they were limiting residents to 100-gallon maximum fills and they were not going to be refilling anyone if the tank was at 30% or more.“We were expecting it to happen but it still sucks,” Undlin said.If that isn’t enough, the lack of supply has caused Undlin’s local propane prices to climb. Price was $1.30/gallon Tuesday and Wednesday it was $2.00/gallon and could climb to $2.50/gallon in the coming days, he said.Undlin said he is only about 10% done with his corn harvest. They planted the crop around normal planting dates, but the corn’s moisture is still 22% to 26%. One positive is yields, which have been roughly about 10% above normal, he said.December is usually extremely cold in north-central North Dakota with high temperatures around zero Fahrenheit — too cold to dry crops. Undlin hopes he can get enough corn harvested to fulfill his contracts; some of his corn may be bagged, while some may just have to stay in the field.The same situation is also present farther east. Roxi Thompson, who farms near Harmony, Minnesota, could not get propane last week to continue harvesting corn.Thompson said Thursday they called their supplier to tell them they would need more supply. It doesn’t appear they will be able obtain more propane anytime soon and it could be up to four weeks before more gas is available, she said. Thompson had received some propane on Monday of this week.“This is serious for us because we still have 700 acres of corn standing in the field, with winter weather on the way,” Thompson said. “For a farmer, the worst feeling in the world is to be unable to do the work they know must be done.”A southern Wisconsin farmer who asked to remain anonymous said he too has not been able to get propane this week as he tries to continue corn harvest. A growing season with 422% above-normal precipitation delayed crops and his corn’s moisture level ranged from 22% to 30%.“We have snow (this week) but our wet tanks are full,” the southern Wisconsin farmer said.He wanted to point out his propane dealer has been great during this ordeal and has done everything possible to obtain propane. More propane was scheduled to arrive at this Wisconsin farm today (Friday) and corn drying will begin again.EXTREME PROPANE DEMANDRoger Leider, executive director of the Minnesota Propane Association, said there is plenty of propane supply in the nation. The pressing issue is the extreme demand. He reported wholesalers in the state are seeing 150% of normal demand at this time of year.Retailers in the state have made priority lists, which include animal confinement facilities and home heating first, while grain drying falls in line second. He has heard from some less-than-happy farmers who want to dry corn, but usually an explanation of the current situation will satisfy them, he said.Leider warned the rest of November will be challenging to keep propane available for everyone who wants it. There are no quick fixes to get large amounts of the product shipped from Conway, Kansas, to Minnesota.“Inventory levels in the state are going to be way down during the month,” Leider said. “I figured it would take 700 semi-loads just to get us back to standard levels and this is on top of the 250 loads we use a day here.”Hopefully, by the end of the month more supply will be available in the state; but even then this recovery period may stretch into December, he said. Leider said the good news is the supply of propane looks to be ample and the price shouldn’t increase much, short of more extremely low temperatures.Russ Quinn can be reached at [email protected] him on Twitter @RussQuinnDTN(ES/CZ)© Copyright 2019 DTN/The Progressive Farmer.

Researchers have poked and prodded and looked at dead cells under electron microscopes, but never before have they been able to get high resolution microscopic views of actual living brain cells as they function inside of a living animal. Now, thanks to work by physicist Stefan Hell and his colleagues at the Max Planck Institute in Germany, that dream is realized. In a paper published in Science, Hell and his team describe the workings of their marvelous discovery. Play STED time-lapse recording of a single spine at an interval of 10 seconds. The measurement includes 128 z-stacks consisting of 5 slices each. Most of the rapid remodeling of the spine head appears continuous and smooth at this frame rate. No damage is observed at the dendrite or the spine after recording a total of 640 slices. The movie was acquired in a different experiment than the spines in Fig.1. Scale bar = 1µm. Video: DOI:10.1126/science.1215369 The new microscope provides clear resolution down to 70 nanometers, which is four times that ever achieved before and is enough to allow scientists to see the actual movement of dendritic spines, which may help researches understand why they do so.It is likely that researchers will find many varied uses for the new microscope. One prominent area will almost certainly involve looking into what psychiatric drugs are really doing within synapses, perhaps leading to breakthroughs in pharmaceutical drugs that are better able to target specific illnesses.One downside to any new scientific breakthrough however, is the natural tendency of many to move from excitation, to wondering about what will come next. In this case, Hell and his team have already started contemplating ideas on ways to allow researchers to study any cell in the living brain at such high resolution, not just those that lie on the surface. © 2011 PhysOrg.com Citation: Renowned physicist invents microscope that can peer at living brain cells (2012, February 3) retrieved 18 August 2019 from https://phys.org/news/2012-02-renowned-physicist-microscope-peer-brain.html Explore further Schematic drawing of the upright STED microscope used for the experiments.

Now, they’ve taken their work to a whole new level by cutting away a small portion of a mouse’s skull and replacing it with a glass window and then placing their latest STED microscope against the glass to peer inside. To make it easier to see what is what, the team first genetically altered the mouse to make certain brain cells fluorescent. Then, to allow for focusing exclusively on just those cells that are lit up, they added software to the microscope to blot out anything that was not lit up. The result is super high resolution real time imagery of the neurons that exist on the exterior part of a living mouse brain.
