OPEN THREAD: You know what to do.

THE NEW SPACE RACE: China will launch 2-in-1 asteroid deflection mission in 2025. “China is now looking to launch its first planetary defense test mission a year earlier than planned and on a larger rocket.”

I’m very much in favor of this capability, but it’s worth noting that when you develop the ability to intercept and impact an asteroid, you’ve developed the ability to intercept and impact a lot of other things.

STOPPED CLOCK: Holy Cow! Whoopi Goldberg Defends Blazing Saddles.

The hosts of “The View” launched into a debate about how classic comedies are aging in 2022 — a topic inspired by Mindy Kaling’s recent comment that “The Office” is “so inappropriate now” and could never be made today.

Goldberg argued the 1974 Mel Brooks flick “Blazing Saddles” “deals with racism by coming at it right, straight, out front, making you think and laugh about it — because, listen, it’s not just racism, it’s all the ‘-isms.’ He hits all the ‘-isms.’”

(…)‘Blazing Saddles,’ because it’s a great comedy, would still go over today — there are a lot of comedies that are not good, OK? We’re just going to say that — that’s not one of them. ‘Blazing Saddles’ is one of the greatest because it hits everybody,” Goldberg insisted.

““Leave my ‘Blazing Saddles’ alone. Don’t make me come for you,” Goldberg quipped at the end of the segment.”

We’ve descended into some sort of bizarre hell-world in which Whoopi Goldberg is a voice of sanity.

JIM JORDAN SINGLE HANDEDLY WRECKED THE DEMOCRATS’ ATTEMPT TO DISCREDIT THE SUPREME COURT: “In a book Schenck wrote titled ‘Costly Grace,’ Schenck made a huge deal out of being recognized as ‘Reverend’ within the Supreme Court, making him the first person in history to be recognized by that title. However, in front of Jordan’s whithering questions, that claim quickly collapsed. Watch as Jordan brutally obliterates Schenck’s false claims with transcripts and audio, and further proves that he’s not credible in any way.”

300,000 KIDS SEX-TRAFFICKED IN TEXAS: Given that fact, the urgent demands for tough action at the border that marked the introduction earlier today by 23 Texas Republican House members make sense.

EVERYTHING’S A TRADEOFF: Germicidal UV lamps: A trade-off between disinfection and air quality.

Disinfecting UVC, also called germicidal UV, lamp systems have long been a cost-effective way to rapidly inactivate airborne pathogens indoors. One design uses lamps that shine at 254 nm, a wavelength that’s damaging to humans’ skin and eyes, requiring the devices to be mounted near the ceiling or inside ventilation ducts. Recently, light at 222 nm has been suggested for whole-room disinfection because the wavelength is reported to be safer for humans.

However, UVC light can set off many reactions. For example, this type of light is known to break apart molecules in the air, forming strong oxidants, such as hydroxyl radicals and ozone. Then these oxidants can convert volatile organic compounds (VOCs) already in the air into peroxides and carbonyl compounds, which can be further broken up by UVC light into organic radicals.

The strong oxidants and organic radicals are known to undergo secondary reactions to generate additional VOCs and particulate matter, some of which could negatively impact people’s health. But the levels of compounds potentially generated from these secondary reactions from GUV systems hadn’t been studied. So, Zhe Peng, Shelly Miller and Jose Jimenez wanted to use computer models to evaluate the possible impact that the two types of UVC air cleaning systems could have on disinfection and air quality in typical indoor conditions.

With computer simulations, the researchers estimated the SARS-CoV-2 virus removal rate and the amount of secondary VOCs that would be generated in three indoor scenarios in conjunction with different room ventilation rates. Initial results indicated that both UVC wavelengths would significantly decrease the risk of infection by SARS-CoV-2 compared to ventilation alone.

The models also projected that the systems would initiate secondary reactions with VOCs expected to be in indoor air. Although only small amounts of secondary VOCs, ozone and particulate matter would likely be produced, the estimated levels weren’t negligible.

I CREDIT PREHISTORIC SPORT UTILITY VEHICLES: Oldest DNA shows Greenland once was home to forested ecosystem. “The sequences were obtained from frozen soil and indicate that the region, was once home to mastodons and reindeer. The area is now barren and home to hare, musk ox and few plants. . . . Greenland was much warmer then, but the researchers did not expect the DNA sequences to reveal forests of poplar, spruce and yew trees such as those now typically found at much lower latitudes, alongside sedges, shrubs and birch-tree species that still grow in Greenland, according to Nature.”
