Does the U.S. Constitution need a makeover?

In an interview about his new book, Yale historian Mark Peterson discusses a widening disconnect between today's America and its Constitution, and the complexity of reworking it. “As a written document,” he says, “our Constitution hasn’t been adapted to accommodate the kind of government we have.”

Your gut does a lot more than digest food. When the intestine isn't functioning well, it affects how your body absorbs the nutrients needed to maintain brain, bone, and muscle health.

Yale gastroenterologist Rosemarie Fisher has spent her career helping patients understand that connection. In a Q&A, she explains what's behind common digestive issues like bloating and IBS, and the straightforward dietary habits that make the biggest difference.

Amid an ongoing nationwide outbreak, cyclosporiasis is causing severe gastrointestinal symptoms for many Americans. The illness can take up to two weeks to cause symptoms after exposure, making it hard to pinpoint the source.

"I can remember what I had for dinner last night," says Yale Medicine's Dr. Scott Roberts. "But it's really hard for me to remember what I had for dinner two weeks ago."

In a Q&A, Roberts explains what causes the infection, which foods have been linked to it, why it's not thought to spread person to person, and when to call a doctor.

Americans are living longer than ever. Yale Law School's Samuel Moyn argues that's had an unexpected consequence: a massive transfer of political power and wealth to older Americans, at the expense of the young.

In his new book, "Gerontocracy in America," Moyn backs that argument with data and proposes some striking remedies: bit.ly/4bhMwtX

Meet Likweli, a newly identified monkey species from the forest canopies of the Democratic Republic of Congo.

Recognizable by striking orange-cream patches around its face, Likweli is so cryptic that residents of only 8 out of 52 villages within its range had any knowledge of it. It took a decade of fieldwork, covering thousands of kilometers of trackless forest, for an international team including Yale researchers to confirm it as a distinct species. It is just the fifth new African monkey species discovered in the past 75 years.

"Discovering a primate species is exceptionally rare," said Yale postdoctoral fellow Julia Arenson, "especially from populations previously unknown to science."

Tiny fossils can tell some really big stories.

Using fossilized fish teeth preserved in ocean sediments, Yale researchers traced the origins of the ocean's most abundant deep-sea fish genus back at least 55 million years, offering new insight into the evolution of life in the deep sea.

Why do some influencers fail to influence?

A new Yale study found that an influencer's success depends not only on who they are, but also on the social network around them. The findings could help shape everything from marketing campaigns to public health messaging.

Heat-related deaths in the U.S. have surged more than 50% since 2000. Yet only about 35% of Americans say they are moderately or very worried about extreme heat.

Yale researcher Jennifer Marlon studies that gap, and her explanation is more nuanced than you might expect. People rely on their own experience to judge risk, she says, but those experiences can lag behind rapidly changing conditions. Las Vegas and Reno are two of the fastest-warming cities in the country, yet many residents still expect each summer to feel like the one before.
