    My SSN was exposed in a breach at Columbia—a school I have no connection with

    When I first started college in 1972, they would post midterm results outside the lecture hall with both the student's name and grade, two lists sorted by name and by grade so you knew where you ranked. Then there were privacy concerns so they started posting them by SS Number. They then...

    Whoops: US military laser strike takes down CBP drone near Mexican border

    You would be an exception then. Flatulence is generally higher in hydrogen that methane.

    Runaway black hole mergers may have built supermassive black holes

    Not being an expert, I believe the fact that the Universe is expanding at an accelerating rate would make this implausible.

    Fermentation is key to coffee beans gleaned from civet feces

    Natural fermentation in this case refers to soaking the beans in water after de-pulping to allow the endogenous enzymes to break down mucilage clinging to the beans. This is typically how Arabica coffee is process. It is rather rare to process Robusta this way.

    The mystery object that struck a plane in flight? It was probably a weather balloon

    Looking at WindBorne's website, it would appear that the balloons operate most of the time above commercial aircraft. Aircraft usually fly at less than 13 km altitude. The WindBorne balloons do dip below this, but spend much of their time above this. Furthermore, when they dip, they pass...

    RFK Jr.’s MAHA wants to make chemtrail conspiracy theories great again

    Well yes, in an indirect way, Tylenol does lead to circumcision. Nearly every husband has encountered a wife with a headache; "Not tonight, dear, I have a headache." But Tylenol can relieve that headache leading to coitus. Sometimes this leads to pregnancies. On occasions a male child is...

    Trump’s claims of a Coca-Cola agreement quickly go flat as nutritionists groan

    While I agree with your assessment that soda has too much sugar, I disagree with your assessment of HFCS. Sucrose is 1/2 fructose (β-D-Fructofuranosyl α-D-glucopyranoside). Sucrose is rapidly hydrolyzed in the stomach so the levels of bloodstream fructose are probably not much different...

    Weird chemical used in plastics has erupted as latest fentanyl adulterant

    Another couple of possible reasons for addition. 1. They are shipping this as BTMPS across borders. BTMPS are fine legitimate products. Who is to notice the fentanyl contamination. 2. It allows the producer to track their products. A BTMP laced shipment gets stolen and ends up being...

    Weird chemical used in plastics has erupted as latest fentanyl adulterant

    Probably liquid chromatography spotted an unidentified peak followed up with spectral and mass spec analysis. Using a mass spec fracture pattern library, candidate compounds can be determined. Final proof comes with adding a known amount of the purported compound to the drug and showing it...

    AI mania pushes Nvidia to record $4 trillion valuation

    This beggars the imagination. Thinking provincially, divided amongst all Americans it would come to $11,700 each. How come I don't feel that AI has improved my life by that amount? I have done very well for myself by avoiding trendy stocks and crypto. Sure lots of people makes boat loads of...

    Reddit user surprised when 1960s computer panel emerged from collapsed family garage

    While cleaning out my father-in-laws Swiss house I stumble across an IBM analog computer. I'm also old enough that I had a course (and then was teaching assistant for) an analog computer class. The patch cords were there, but no power supply. I thought about shipping it home. Regrettably I...

    Man suffers chemical burn that lasted months after squeezing limes

    As a biochemist I was aware of the protease capability of pineapple juice. But this was driven home a few years ago when my wife bought prepared shish kababs featuring pineapple and shrimp. They looked delicious. When I got them out the next evening to barbeque, the shrimp had literally...

    Man suffers chemical burn that lasted months after squeezing limes

    My brother experienced this. A sunny afternoon of Gin Tonics with fresh lime squeezed in. His hands peeled for days. He won't touch the fruit now. When I visit I get the job of squeezing the limes.

    Probably solanine poisoning. Potato peels exposed to light produce this toxin.

    The sad, bizarre tale of hype fanning fears modern cryptography was slain

    I saw a reference to the South China article in my news feed. I went, "We'll see, I will await an analysis by some better authority". Ars didn't let me down.

    I live in the Columbus area and have been following this case closely. Goodwolf involved a local TV station. He showed the TV reporter that the data was legible and highly sensitive, contrary to the claims of the city. The TV report that followed showed screen shots but with personal...
