Beyond regulating brightness, 4 US states ban billboards entirely. (Hawaii, Alaska, Vermont, & Maine)
While a bee stinger may get stuck in you, that's not so when stinging fellow insects. The barbs don't catch on an exoskeleton like they do for thick and elastic mammalian skin. An elegant way to deliver more venom to…
Tungsten carbide jewelry is a mixture of tungsten carbide powder and a metal binder, typically cobalt or nickel. The metal binder is electrically conductive and thus susceptible to the induction heating you felt.
It's more than just the chain length. The most common synthetic rubbers are styrene-butadiene copolymers. Natural rubber is polyisoprene. While it is true that shorter chain synthetic polyisoprene is available, it is a…
Surely the process of using fingers to measure discrete pulses is digital.
Ethane (R-170) is a fine low-temperature refrigerant for lab equipment. The performance characteristics are at least as good as halocarbon refrigerants. The main drawback is flammability but propane has a similar…
This is largely a story about excessive copyright duration. The casting requirement for this 70 year old play is based on legal threats by the estate of the author who died over 30 years ago.
A correction. The Kudo et al., 2002 study found that estradiol lowered the filtration rate in ovariectomised rats. But supplemental estradiol did improve the clearance rate for intact male rats.
Unfortunately this sort of mining has long-term impacts on deep sea ecology. It causes substantial loss of species diversity and activity even 26 years later, with this paper estimating recovery will take at least 50…
I've found this site helpful. Not exhaustive, but reasonably accurate for the types it lists. https://www.pickyourown.org/USharvestcalendar.htm
These days I use the "hourly graphical forecast" from the National Weather Service. I've found it to be at least as accurate as Dark Sky and easy enough to display 3 images side by side and refresh periodically to…
Most of evolution is repurposing existing infrastructure for different purposes; The details are still interesting.
I had someone try the same grift to me in NYC but they went for my decoy pocket that only had used tissues.
Plenty of fiberglass uses polyester resin rather than epoxy.
The largest unit demonstrated in this video output 35 watts. Not quite 5 megawatts, lest anyone get the wrong idea. That's mentioned in the paper linked in the description. https://arc.aiaa.org/doi/abs/10.2514/3.48057
The information density is even higher than that (double), because one pair of bases has 4 possible states. The pair A-T is symbolically distinct from T-A, for example.
It boggles my mind that the general public, media, and even healthcare workers treat N95 mask as if they are as good as it gets. Industry routinely uses elastomeric half- and full-face respirators with P100 filters, and…
Or using a better source video. As there's no way the original film was interlaced.
There are dozens of bumblebee species in Vermont, but Bombus impatiens is particularly common. That's much more likely than B. pensylvanicus mentioned in the article.
HEPA filters were developed for radioactive dust during the Manhattan Project. Only several years later did the technology get declassified and started being used in biology and medicine.
In New York the majority of land use regulations are at the town/city level rather than county or state.
~40% of Americans live in states that have laws against wearing a mask in public spaces. Preventing people from protecting themselves is absolutely a live issue. http://www.anapsid.org/cnd/mcs/maskcodes.html
If it's optimizing for combustion cars it won't be a perfect match for electric. The ICE route will penalize intersections and hills due to engine idling and lack of regenerative braking.
In case anyone is wondered why there is benzene in hand sanitizer: Ethanol forms an azeotrope with water, which makes it impossible to dry completely without further processing. Benzene forms its own azeotrope with…
This is the basis for customary nail sizes, as it's (for example) how many 6d nails you could get for 6 pennies in medieval England. https://en.wikipedia.org/wiki/Penny_(unit)
