Why Some of Us Seek Dominant Partners
"The results revealed that sensation-seekers of both genders were especially likely to prefer a dominant partner. In particular, boredom susceptibility and disinhibition were correlated with a preference for dominant partners—while thrill-seeking was not. This suggests that those who are easily bored and engage in impulsive behaviors may choose more dominant romantic partners. Such partners may provide the excitement that keeps them stimulated."
How long do vaccines last? The surprising answers may help protect people longer
"In a 2018 review of 11 recent studies on the durability of influenza vaccines, researchers concluded that effectiveness can vanish as soon as 90 days after vaccination. The article, published in Clinical Infectious Diseases, further noted that 20% of Americans received their flu vaccines for a given season by the end of September—which means the vaccine may do nothing come peak flu spread in January and February... By the 2000s, the country had only a few hundred cases per year. But then in 2006, mumps surged on college campuses in the Midwest, with 6500 cases tallied before the year's end. Nearly 85% of the college-age people who became ill had received the recommended two doses of the mumps vaccine. Despite wide use of the vaccine, mumps outbreaks continue in the United States on college campuses and in tightly knit religious communities..." Implies the vaccine itself loses effectiveness, because a new mumps strain that has genetically "escaped" should strike other age groups just as often. In a dozen other studies of mumps outbreaks around the world, researchers have also found signs of waning protection.
(DNA Learning Analogy in Comments) Why did my hair change from blonde as a child to brunette in my teens?
"DNA is the recipe in a cookbook that can't leave your Grandma's house (nucleus). You want it so you copy (transcribe) the instructions onto a post-it to take home with you (mRNA). It's still just a code; you can't eat the post-it, and it looks slightly different than the format in the actual cookbook but contains the same information. You then take this into your kitchen (the ribosome) and then as the cook (tRNA) you read (or translate) the words and then assemble the ingredients. So you know that egg means those oval things in the fridge just like tRNA knows that AUG (we call the words codons) means the amino acid methionine. Assemble the right ingredients and you have your food (chocolate cake!) or protein (red hair)."
Banned in 160 Nations, Why is Ractopamine in U.S. Pork?
"It belongs to a class of drugs, beta-agonists, that were developed to treat asthma and only adapted for animal use when they were shown to boost growth rates. The U.S. Food and Drug Administration (FDA) approved ractopamine for use on pigs after just one human health study — an evaluation of six young, healthy men, one of whom dropped out because his heart began racing and pounding abnormally. Three years later, the FDA sent ractopamine's sponsor a 14-page letter, accusing the company of withholding information about the drug's "adverse animal drug experiences" and "safety and effectiveness." Shortly thereafter, the FDA required drug manufacturers to add this warning label: "Ractopamine may increase the number of injured and/or fatigued pigs during marketing. Not for use in breeding swine."... The FDA has linked ractopamine to nearly a quarter-million reported adverse events in pigs (more than half of those pigs were sickened or killed) — more than any other animal drug. These pigs became lame or unable to stand, started trembling, or suffered a host of other ailments. In particular, ractopamine causes pigs to collapse and become "downers," that is, animals too sick or injured to walk, and then often dragged into the slaughterhouse."
YouTube Manipulated ‘Federal Reserve’ Search Results in Response to MSNBC Host’s Complaint
"... the term “Federal Reserve” has also been on the blacklist since September of last year – and it’s all because someone at Google read a series of Chris Hayes tweets... According to the source, an employee at the company drew attention to Hayes’ tweets a day after the MSNBC host posted them. On the same day, the source says Google’s “youtube_controversial_query_blacklist” file was edited to include the term “Federal Reserve.”... previously reported on Google’s decision to add the terms “abortion” and “abortions” to the same YouTube search blacklist." I actually know this is true because I watched the youtuber prior to the video being blacklisted. I had already seen the video and knew it was first on the results before google's edit because it was something I'd shared a few times to people. Still shocked that the US govt sided with youtube that they were a 'Forum' when clearly editing search results means you are not by definition a Public Forum under law... sigh. A Forum being like a place where all peoples voices can be heard and not filtered, like people debating philosophy in a public square in Greece - like in Monty Python.
Why Interacting with a Woman Can Leave Men “Cognitively Impaired”
"... study demonstrated that after a short interaction with an attractive woman, men experienced a decline in mental performance. A more recent study suggests that this cognitive impairment takes hold even when men simply anticipate interacting with a woman who they know very little about... The results may also have to do with social expectations. Our society may place more pressure on men to impress women during social interactions." I've been self-observing this phenomena for years. Actually read about it later on, in a psychology textbook. It is frustrating for me as a female who somewhat ranks men based on their intellectual stamina, learning it made me give men more time and not judge as harshly.
