When Charles Darwin made the famous voyage that took him to the Galapagos, he marveled at the giant tortoises that lumbered across the islands. He tried to ride them. He ate their flesh. He followed the paths they created in their ponderous travels. And he mused at their differing shapes on different islands, insights that helped steer him toward his theory of evolution by natural selection.
“It is the circumstance, that several of the islands possess their own species of the tortoise, mocking-thrush, finches, and numerous plants, these species having the same general habits, occupying analogous situations, and obviously filling the same place in the natural economy of this archipelago, that strikes me with wonder,” Darwin wrote in his account of the trip, The Voyage of the Beagle.
What he didn’t fully appreciate—at least judging by his writings—is the critical role the enormous reptiles played in shaping the plant communities of these islands. But the return of thousands of giant tortoises to the Galapagos island of Española is giving scientists new insights into the transformative power these behemoths wield. It is the latest in a long list of scientific discoveries emerging from the tiny cluster of islands off the coast of Ecuador. And it holds out the potential for restoring island ecosystems in part by reviving reptile herbivores.

For years, Alzheimer’s conferences were like the obituary pages in the local newspaper: It’s where clinicians and researchers in the field went to find out the names of the latest promising drugs to die. Between 1998 and 2017 alone, 146 clinical trials of new Alzheimer’s drugs failed.
Israel has ordered more than a million people to leave northern Gaza, presumably to prepare for an imminent ground offensive. Its military strategists appear to be planning the depopulation and reoccupation of at least part of an area home to around 2.3 million people —

In the Arab world, people have been as quick to show support for Palestine as most American politicians have for Israel. On Friday, after prayers at Egypt’s al-Azhar Mosque, protesters filled the streets. As did tens of thousands of
Section 301, in the second-to-highest tier of Levi’s Stadium, floats 105 feet above Santa Clara, Calif. It comprises 251 seats — a mere hamlet in the vast 64,000-seat general kingdom of the place, but it was our hamlet, and on the last Saturday in July, we took up each one of those seats and watched, our collective breath held, as Taylor Swift emerged from a bevy of billowing pastel parachutes and rose up on a platform to perform the 47th show of her Eras Tour. A few songs in, she announced, laughing, that her father told her that Santa Clara had named her its honorary mayor during her two-night stay there and that the entire town had been
It was a more physical world, though we thought it quite advanced. There seemed nothing “terrestrial” about twisting a radio knob to some eccentric decimal point, dialling static into song. In the summer of 1985, we all knew someone, usually an older sibling, who owned a portable, cassette-playing stereo. The rest of us remained stuck catching Top Forty countdowns on AM radio, or playing, on our parents’ imperial turntables, the one or two LPs in our possession. Increasingly, we listened to music by watching it on TV, our dance parties often overseen by a strutting, tattered sprite who wore bangles like opera gloves and held the camera’s gaze with her entire being, as though locked in a dare she was not going to lose.
In the book, Dennett describes his intellectual growth and the role he played in many philosophy developments over the years. There’s plenty of inside baseball, but it is lively reading even for those with no stake in the game.

Hamas’s brazen and vicious attacks within Israel have rightly drawn condemnation from around the world. If this is a war, as both sides agree it is, then Hamas’s deliberate targeting of civilians counts as a major war crime.
AMONG THE OLDEST REFERENCES to menstruation in literature is in the book of Genesis, in a story about a lie. Rachel stole her father’s household gods, it goes, and when he came to retrieve them, she threw a covering over the objects and sat on it. She couldn’t stand, she apologized to her father, because she was in “the way of women.” At the end of the sixteenth century, an English clergyman clarified in his guide to Genesis that Rachel wasn’t pretending to be incapable of standing, just uncomfortable, due to her “monethly custome,” an ancestor to our contemporary “period.” As Jenni Nuttall explains in her new book Mother Tongue: The Surprising History of Women’s Words, “period” has been in use to name a quantity of time since the Middle Ages, but “only at the end of the seventeenth century”—so, a little after the clergyman’s time—“does the phrase ‘monthly period’ appear in medical books as a name for menstruation.”

How we grow old gracefully—and whether we can do anything to slow down the process—has long been a fascination of humanity. However, despite continued research the answer to how we can successfully combat aging still remains elusive.
Over the last several decades, the rates of new cases of lung cancer have fallen in the United States. There were roughly 65
The prize changed our lives. It is the one scientific prize everyone knows. Suddenly you become a public figure being asked to do all sorts of things: to give lectures, quite often on topics you know little about; to sit on committees and reviews you are not always well qualified to be on; to visit countries you have barely heard of; to sign endless petitions on what are probably good causes, but you never know. It is like having a whole new extra job, with upwards of 500 requests a year. It is
