For decades, eating disorders were thought to afflict mostly, if not exclusively, women and girls. In fact, until 2013, the loss of menstruation had long been considered an official symptom of anorexia nervosa.Over the last decade, however, health experts have increasingly recognized that boys and men also suffer from eating disorders, and they have gained a better understanding of how differently the illness presents in that group. A small but growing body of scientists and physicians have dedicated themselves to identifying the problem, assessing its scope and developing treatments.Recently, two of these experts spoke to The New York Times about how the disease is affecting adolescent boys, what symptoms and behaviors parents should look for, and which treatments to consider.

Sea surface temperatures were just slightly lower than in August 2023, the oceans’ warmest month on the books. And sea temperatures kept on climbing in the first few days of February, surpassing the daily records set last August.The oceans absorb the great majority of the extra heat that greenhouse gases in the atmosphere trap near Earth’s surface, making them a reliable gauge of how much and how quickly we are warming the planet. Warmer oceans provide ...

The number of monarch butterflies at their overwintering areas in Mexico dropped precipitously this year to the second-lowest level on record, according to an annual survey.The census, considered a benchmark of the species’s health, found that the butterflies occupied only about 2.2 acres of forest in central Mexico, down 59 percent from the prior year. Only the winter of 2013-14 had fewer butterflies.Scientists said the decline appeared to be driven by hot, dry conditions in the United States and Canada that reduced the quality of available milkweed, the only plants monarch caterpillars can eat, as well as the availability of nectar from many kinds of flowers, which they feed on as butterflies.“It’s telling us that we need to intensify conservation and restoration measures,” said Jorge Ri...
