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.

Norovirus sickens hundreds of millions of people each year, yet there are still no vaccines or antiviral drugs to prevent it. A Yale study suggests future vaccines may be more effective if they target the gut, where the virus strikes. Read more: bit.ly/4goHkIe

It looked like a poisoning. It took 400 years and a genetic analysis to prove it wasn't. When Grand Duke Francesco de Medici and his wife died on consecutive days in 1587, rumors spread that his brother and rival, Cardinal Ferdinando, had poisoned them with arsenic. A new study co-led by Yale researchers has settled the question with genetic certainty. Malaria, not poison, killed them both. The analysis also recovered a novel strain of the deadliest malaria parasite from the remains, offering new insight into how the disease spread and evolved across Renaissance-era Europe.

More than 30 years of research have led to a new treatment for children with Type 1 diabetes. Yale researcher Kevan Herold helped lead the clinical trial behind teplizumab, an immunotherapy now approved by the FDA for children with Stage 3 Type 1 diabetes. “This is paradigm shifting for the field,” Herold said. Explore how this treatment is changing the future of diabetes care: bit.ly/3R9KUeW

Yale scientists are uncovering the secret lives of salamanders. For decades, woodland salamanders were considered a textbook example of species that split apart without really changing. A new Yale-led study of 30 species found otherwise. While their bodies look much the same, their physiology has evolved rapidly, with striking differences in cold tolerance, metabolic rate, and water loss resistance across species.

At a ceremony held at the Danbury Federal Correctional Institution in Connecticut, 11 women recently became the first graduates of the only college degree program operating in any federal women's prison in the U.S. One graduate is now training to be a nurse. "I really do have a future," she said. Read their stories and learn about the Yale Prison Education Initiative: bit.ly/3Sj2Rbl

Yale researchers are proposing ‘copyleft’ rules for generative AI. Many AI models are built on free and open-source software. But the open-source community — which puts a high value on transparency — is often in the dark about how its work is used. A new study out of Yale’s Digital Ethics Center suggests a way to resolve this tension by extending a twist on copyright rules. Learn more: bit.ly/4wcc0kC

A summer night atop East Rock taking in the views of our campus and home city.

Before the United States was a nation, Yale was already part of its story. During the American Revolution, many Yale students, alumni, and leaders took up the patriots' cause as war reached New Haven and the campus itself. Explore the story: bit.ly/4oVIOf6

Celebrating America 250. 🇺🇸 When the Declaration of Independence was signed in 1776, Yale was already 75 years old. As the United States marks its 250th birthday, Yale News has gathered the stories, exhibitions, walking tours, and historical collections that connect these two deeply intertwined histories. Explore it all: bit.ly/4eUbCQD

The best classrooms inspire learning on both sides of the room. Each year, Faculty Bulldog Days lets Yale instructors become students again, visiting open classes across disciplines. Fall session: October 5–9. Registration is open. Learn more: bit.ly/4behKC7

A new vision for quantum computing is taking a big step forward. A Yale-led project called ERASE has received a $4 million National Science Foundation grant to advance a quantum computer design built around a key innovation: qubits that can identify their own errors when they occur, making them significantly easier to correct. The grant will also expand quantum workforce development in New Haven. Read how the project works and what comes next: bit.ly/4wlkBl8

Much of the country is under extreme heat this week. David Della-Giustina knows firsthand what that feels like. A retired Army colonel who served as a physician during combat tours in Afghanistan and Iraq, he is now a Yale emergency medicine specialist. In a Q&A, he breaks down the difference between heat exhaustion and heat stroke, who is most at risk, and the counterintuitive clothing tip that can actually keep you cooler in direct sunlight. Read his advice before heading outside: bit.ly/3QMHheE

A perfect summer evening on the New Haven Green. 🎶 The New Haven Symphony Orchestra, joined by Capathia Jenkins and Ryan Shaw, delighted the crowd during the International Festival of Arts & Ideas, an annual New Haven tradition that transforms our home city with performances, art, and conversations for all. @ArtIdea

Yale astronomers have found a third galaxy with almost no dark matter, and it sits in a straight line with the first two. All three appear to have formed in the same violent cosmic collision. A line of dark-matter-free galaxies has never been seen before. Read how the discovery unfolded: bit.ly/4oKNN2d

AI can already help radiologists catch breast cancers they might otherwise miss. But Yale radiologist John Lewin says the more transformative capability is what comes next, using AI to predict a patient's future risk of developing breast cancer, years before any sign of it appears. In a Q&A, Lewin explains how the technology works, where it stands today, and what it could mean for screening: bit.ly/4uNaiot

Ancient DNA is helping scientists better understand how humans evolved. In a new Yale study, researchers analyzed genomes from Oceania and found that DNA inherited from extinct human relatives helped early humans adapt to their environments and continues to influence biology today.
