About a month ago, Judith Hansen popped awake in the predawn hours, thinking about her father’s brain. Her father, Morrie Markoff, was an unusual man. At 110, he was thought to be the oldest in the United States. His brain was unusual, too, even after he recovered from a stroke at 99. Although he left…
I once decorated a mirror with shells, but I keep it in a closet. I’m fond of it, even though it looks a little sloppy. Sometimes I’ll debate whether to toss it, and then gently put it back on the shelf. As it turns out, a lot of us have strong attachments to things we…
In July 2016, a heat wave hit Boston, with daytime temperatures averaging 92 degrees for five days in a row. Some local university students who were staying in town for the summer got lucky and were living in dorms with central air-conditioning. Other students, not so much — they were stuck in older dorms without…
Your grandma’s brownies, the scent of rain on a pine forest, a whiff of cardamom — smells can be powerful time machines, unlocking memories almost like magic and transporting you to specific moments more vividly than vision or hearing. But just like vision and hearing, our sense of smell diminishes with age (and as a…
Fluctuating disease rates, innovative treatments and talk of “moonshots” in the White House may make cancer seem like a modern scourge. But a new discovery highlights how humans dealt with the illness and hunted for cures as far back as the time of the ancient Egyptians. Scientists led by Edgard Camarós, a paleopathologist at the…
Just four months ago, Noland Arbaugh had a circle of bone removed from his skull and hair-thin sensor tentacles slipped into his brain. A computer about the size of a small stack of quarters was placed on top and the hole was sealed. Paralyzed below the neck, Mr. Arbaugh is the first patient to take…
Everyone feels lonely from time to time — after, say, a move to a new school or city, when a child leaves for college, or following the loss of a spouse. Some people, though, experience loneliness not just transiently but chronically. It becomes “a personality trait, something that’s pretty sticky,” said Dr. Ellen Lee, an…
Robert F. Kennedy Jr.’s disclosure that a doctor apparently found a dead worm in his brain has sparked questions about what brain parasites are, the damage they can cause and how, exactly, they get there. How do parasites turn up in people? And what can they do to the brain? Brain parasites encompass far more…
In 2010, Robert F. Kennedy Jr. was experiencing memory loss and mental fogginess so severe that a friend grew concerned he might have a brain tumor. Mr. Kennedy said he consulted several of the country’s top neurologists, many of whom had either treated or spoken to his uncle, Senator Edward M. Kennedy, before his death…
Consumers have grown accustomed to the prospect that their personal data, such as email addresses, social contacts, browsing history and genetic ancestry, are being collected and often resold by the apps and the digital services they use. With the advent of consumer neurotechnologies, the data being collected is becoming ever more intimate. One headband serves…
