Digitization promises to make medical care easier and more efficient. But are screens coming between doctors and patients?

Kids discover lying as early as age 2, studies have found. In one experiment, children were asked not to peek at a toy hidden behind them while the researcher withdrew from the room under false pretenses. Minutes later, the researcher returned and asked the child if he or she peeked.

was in my late forties when I finally admitted to myself that I would never love wine. As other women fake orgasms, I have faked hundreds of satisfied responses to hundreds of glasses—not a difficult feat, since my father schooled my brother and me in the vocabulary of wine from an early age. Confronted with another Bordeaux or Burgundy, I could toss around the terms I had learned at the dinner table (Pétillant! Phylloxera! Jeroboam!), then painstakingly direct the wine straight down the center of my tongue, a route that limited my palate’s exposure to what it perceived as discomfiting intensity.

When the artist Peggy Weil first learned about the National Ice Core Laboratory, a few years ago, she was captivated. She contacted Geoffrey Hargreaves, the lab’s curator, and soon found herself inside a giant freezer, bundled in an Arctic-ready parka. (The temperature was minus thirty-eight degrees Fahrenheit.) With the help of lab assistants, she loaded up a cart with cannisters made of thick cardboard, each containing a small segment of a two-mile-long core from the Greenland ice sheet. Weil trundled her specimens to a cylindrical scanner and photographed them in high resolution. Eventually, she strung together eighty-eight scans, top to bottom. Then she animated them and added an accompanying score, creating a four-and-a-half-hour video, designed to be projected onto a wall.

The album was disintegrating, and we removed the cards. Over the years I forgot about them, but in getting ready to move, I came across them again. One in particular is offensive in its captioning and art to people of African descent. While I presume there is a market for this type of memorabilia, there is no way I would seek to profit from it. I offered it to the National Museum of African American History and Culture in Washington. I never heard from them, so it moved with us.My husband thinks I should throw it away, but that feels wrong. I feel it is history that we should acknowledge, however painful and wrong. Your thoughts?

As machine learning becomes more powerful, the field’s researchers increasingly find themselves unable to account for what their algorithms know — or how they know it.

ARE you responsible for your behavior if your brain “made you do it”?Often we think not. For example, research now suggests that the brain’s frontal lobes, which are crucial for self-control, are not yet mature in adolescents. This finding has helped shape attitudes about whether young people are fully responsible for their actions. In 2005, when the Supreme Court ruled that the death penalty for juveniles was unconstitutional, its decision explicitly took into consideration that “parts of the brain involved in behavior control continue to mature through late adolescence.”

To what extent can we and should we aspire to create machines that can outthink us? For example, Netflix has an algorithm that can predict what movies you will like based on the ones you've already seen and rated. Suppose a dating site were to develop a similar algorithm—maybe even a more sophisticated one—and predict with some accuracy which partner would be the best match for you. Whose advice would you trust more? The advice of the smart dating app or the advice of your parents or your friends?

The question, it seems to me, is should we use new genetic technologies only to cure disease and repair injury, or also to make ourselves better-than-well. Should we aspire to become the masters of our natures to protect our children and improve their life prospects?AdvertisementAdvertisement This goes back to the role of accident. Is the unpredictability of the child an important precondition of the unconditional love of parents for children? My worry is that if we go beyond health, we run the risk of turning parenthood into an extension of the consumer society.

For almost all her life, Verda Byrd has lived as a black women. She was raised by black parents, married a black man, attended black churches, and even frequented black hair salons. But two years ago, she learned from her adoption papers that she was actually white.  Verda was legally born Jeanette Beagle, daughter to a poor white woman named Daisy Beagle, who struggled to raise several kids in the 1940's.  She was put into a children's home after her biological mother was injured in an accident. A few years later, Jeanette was adopted by a black couple  — and she became Verda.  Although her adopted parents told Verda she wasn't biologically theirs, they never told her that she was white. The discovery prompted Verda to reunite with her biological sisters. Through the reconnection, she learned that her perspective of race was far different from theirs. 

Marsh, who is now sixty-five, is one of Britain’s foremost neurosurgeons. He is a senior consultant at St. George’s Hospital, in London, and he helped to pioneer a kind of surgery in which patients are kept awake, under local anesthesia, so that they can converse with their surgeons while they operate, allowing them to avoid damaging what neurosurgeons call “eloquent,” or useful, parts of the brain. Marsh has been the subject of two documentary films. Still, he writes, “As I approach the end of my career I feel an increasing obligation to bear witness to past mistakes I have made.” A few years ago, he prepared a lecture called “All My Worst Mistakes.” For months, he lay awake in the mornings, remembering the patients he had failed. “The more I thought about the past,” he recalls in his book, “the more mistakes rose to the surface, like poisonous methane stirred up from a stagnant pond.”

What makes one human better at talking about odors than another? Are English speakers flawed smellers, or are the hunter-gatherers of the Malay Peninsula exceptional?
