From Science Daily:
Melanie Rutkowski, PhD, of UVA’s Department of Microbiology, Immunology and Cancer Biology, found that disrupting the microbiome of mice caused hormone receptor-positive breast cancer to become more aggressive. Altering the microbiome, the collection of microorganisms that live in the gut and elsewhere, had dramatic effects in the body, priming the cancer to spread. “When we disrupted the microbiome’s equilibrium in mice by chronically treating them antibiotics, it resulted in inflammation systemically and within the mammary tissue,” she said. “In this inflamed environment, tumor cells were much more able to disseminate from the tissue into the blood and to the lungs, which is a major site for hormone receptor-positive breast cancer to metastasize.”
Most breast cancers — 65 percent or more — are hormone receptor positive. That means their growth is fueled by a hormone, either estrogen or progesterone. The good news is that these types of cancers are likely to respond well to hormone therapy. Predicting whether such cancers will spread beyond the breast to other parts of the body (a process called metastasis) is a major challenge within the field, and is primarily driven by clinical characteristics at the time of diagnosis. Early metastasis is affected by a variety of factors, Rutkowski explained. “One of them is having a high level of [immune] cells called macrophages present within the tissue,” she said. “There have also been studies that have demonstrated that increased amounts of the structural protein collagen in the tissue and tumor also lead to increased breast cancer metastasis.”
Having an unhealthy microbiome prior to breast cancer increased both, and the effect was powerful and sustained.

Justice Ruth Bader Ginsburg grew up with a solid old-school Brooklyn accent. She displays no trace of it in recordings of her work as a young litigator, but today, one can hear shades of it in her speech on and off the court. Why?

When moral visions clash, it’s common for people to assume their opponents have bad motives rather than different perspectives. And it’s usually wrong. If you advocate some policy you believe will save lives, whether it’s a plan for fighting COVID-19, increasing health-care coverage, or reducing homicide, your opponents probably don’t oppose your plan because they want more people to die. They may think their own plan will save lives, or they may be concerned about other values entirely. You may very well have fundamental moral disagreements with them, but the thing you hate most about their position probably isn’t what’s driving them.
Cyan (pronounced SIGH-ann) is the color that emanates from a calm sea not far offshore on a clear day as the blue of the sky is reflected in salt water awash over yellow sand. You can see it for yourself in postcards mailed from coastal resorts or, if you are at a resort, from a vantage point somewhere above the beach—from a cliff, say, or lacking cliffs, from atop a palm tree. Various shades of cyan form the background to the ad for Swarovski (whatever that is) on page 13 of the April 2005 issue of Gourmet magazine. To create a highly saturated cyan on your own, you might pour 1/4 cup of Arm & Hammer’s Powerfully Clean Naturally Fresh Clean Burst laundry detergent onto the whites in your next load of wash (presumably Arm & Hammer adds the pigment to its product in order to provoke association with what we imagine to be the pristine purity of tropical seas). Also, you might search for “cyan” at wikipedia.org, where a resplendent rectangle of the color is on display, along with a succinct definition: “Cyan is a pure spectral color, but the same hue can also be generated by mixing equal amounts of green and blue light. As such, cyan is the complement of red: cyan pigments absorb red light. Cyan is sometimes called blue-green or turquoise and often goes undistinguished from light blue.”
Even though the year is only a little more than halfway gone, 2020 has understandably been filled with talk about the “solace” of reading. More so than in any previous year in living memory, readers have been diving into books in order to escape the harsh realities of the outside world. In her new book “Austen Years: A Memoir in Five Novels,” award-winning author Rachel Cohen writes of exactly this kind of solace-seeking. While dealing with her father’s death and the birth of her daughter, Cohen found herself in a readerly relationship with the novels of Jane Austen that was more fixed, almost more compulsory, than anything she’d previously imagined for herself. In the opening pages, she muses that “if you had told me that years were coming when I would hardly pick up another serious writer with any real concentration, that the doings of a few English families would come to define almost the entire territory of my reading imagination, and that I would reach a point of such familiarity that I would simply let Austen’s books fall open and read a sentence or two as people in other times and places might use an almanac to soothe and predict, I would have been appalled.”

On this week’s books podcast, my guess is Oxford University’s Professor of European Archaeology, Chris Gosden. Chris’s new book The History of Magic: From Alchemy to Witchcraft, From the Ice Age to the Present opens up what he sees as a side of human history that has been occluded by propaganda from science and religion. Accordingly, he delves back to evidence from the earliest human settlements all over the world to learn about our magical past – one thread in what he calls the ‘triple-helix’ of our cultural history. He tells me why John Dee got a bad rap, where magic wands came from – and why, unusually as an academic, he argues that magic isn’t just an anthropological curiosity but might, in fact, have something useful to teach us.

Schneider: It depends upon the larger social and political setting. Several large research projects are currently trying to put AI inside the brain and peripheral nervous system. They aim to hook you to the cloud without the intermediary of a keyboard. For corporations doing this, such as Neuralink, Facebook and Kernel, your brain and body is an arena for future profit. Without proper legislative guardrails, your thoughts and biometric data could be sold to the highest bidder, and authoritarian dictatorships will have the ultimate mind control device. So, privacy safeguards are essential.
The Greek philosopher Aristotle did not merely condone slavery, he defended it; he did not merely defend it, but defended it as beneficial to the slave. His view was that some people are, by nature, unable to pursue their own good, and best suited to be “living tools” for use by other people: “The slave is a part of the master, a living but separated part of his bodily frame.”
