Periodic fasting may have positive health benefits, but is difficult for most people to handle. Here's work looking at a modified form of periodic dietary restriction that could be easier. Early results look promising, but it is still far too early to tell.
A curious thing about slavery is that it was on the decline in the US until the Industrial Revolution created an enormous demand for cotton. The cotton gin and a few other inventions made massive plantation farming using slave-labor practical and inexpensive.
No matter where you stand on this issue, most car companies today take the position that the data and software inside that shiny new car of yours doesn’t belong to you, it belongs to them. They only give you a license to use it when you buy or lease the car. Apparently, the powers that in Michigan (car companies) don’t trust the feds to adequately protect them. They want their position enshrined in local law, complete with the threat of life in prison if you disobey them. Somewhere, George Orwell is smiling.
Under calm daylight conditions, the level of CO2 in a tree canopy drops below that in the surrounding atmosphere as the gas moves into leaves and is used in photosynthesis. A slight breeze will mix the air and replace some of the CO2 , but if the CO2 level in the leaf canopy is to be maintained, wind speed will need to be about 12 mph. Winds of this speed may increase photosynthesis by 10 to 20 percent if other factors are not limiting. Unfortunately, respiration also may increase by 20 to 40 percent in moderate winds. This increase is due to effects on stomatal gas exchange or in response to leaves being ripped or otherwise damaged.
It impresses me that although the progress of technology can be swift, certain standards become embedded and hang around as a technology is replaced by another. When Herman Hollerith invented punch-card data processing for the 1890 census he economized by making punch cards the size of American paper money so relatively inexpensive mass-produced paper currency file boxes could be used for storage. Originally the punch cards had 45 columns, but IBM increased it to 80 in the 1920s. 80 columns stuck and denser standards that appeared later never caught on. Punch cards were commonly used to program computers until the late 70s and computer language FORTRAN had 80 column lines built-in. Video terminals displaced punch cards, but until windowing interfaces took over most were based on 80 column lines. You still find remnants of the old IBM standard that was fixed by the size of American paper money in the 1890s...
