In 2010, the New York City-based restaurant Serendipity 3 revealed its $69 hot dog, winning the Guinness World Record for the world's most expensive hot dog. Served on a toasted pretzel roll with truffle butter and covered in foie gras, the award-winning hot dog made the restaurant's $18 cheeseburger seem like a steal. That's the point, says Professor Damon Centola of the Annenberg School for Communication at the University of Pennsylvania.

An international team of researchers including our Department of Geography has discovered a vast geological structure hidden beneath the East Antarctic Ice Sheet. The findings are published in the journal Nature Geoscience.

Young guppies who were able to see and interact with live fish developed larger brains than guppies who only saw other fish on a screen. This is shown in a new study from Stockholm University, published in Biology Letters. The findings suggest that live social interaction in real time may be important for brain development.

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a new method to recycle mixed plastic packaging without using harmful chemical solvents—an approach that could make one of the world's most difficult waste streams significantly easier to handle.

Why do certain surfaces behave very differently from what theoretical calculations suggest? Scientists long assumed that the aluminum oxide surface should be highly reactive and capable of splitting water molecules. In experiments, however, this behavior is barely observed.

A new study in Nature Communications finds a critical climate tipping point in Tibetan permafrost ecosystems. Warming of 2–4 degrees Celsius triggers a self-reinforcing cycle of carbon release that could significantly accelerate climate change, according to the work.

A research team led by Professor Nenad Miljkovic in The Grainger College of Engineering at the University of Illinois Urbana-Champaign has published a breakthrough study in Nature Physics. The work reports the first experimental discovery of a previously unknown frost propagation mechanism—a "suspended ice bridge"—offering new pathways for anti-frosting surface design.

Plastic pollution is widespread in the world's oceans. A new study of northern fulmars from the North Atlantic shows that plastic pollution is also common in northern marine areas. The research is published in the journal Marine Pollution Bulletin.

UNSW Sydney engineers have riffed on the famous Schrödinger's cat analogy to demonstrate a more efficient way to eliminate errors in quantum computing.

The first comprehensive map of nearly the entire Greenland shark genome is beginning to reveal some of the genetic clues behind its incredibly long life. The work could one day help scientists develop new cures and treatments for cancer and other age-related diseases.

Affective polarization—i.e., an aversion toward supporters of the opposing party—has been shaping American society for years, including when it comes to finding a partner. A new sociological study by Dr. Ansgar Hudde and Shannon Taflinger from the University of Cologne's Department of Sociology and Social Psychology dives deeper into this phenomenon, examining how political information on a dating profile influences the romantic interest of young Americans. The study was published under the title "Why do young U.S. Americans avoid cross-partisan dating? A closer look at mediators and variation by gender and party" in the journal European Sociological Review.

Interactions between hard-shelled marine mollusks such as clams and snails and their predators play a critical but largely unseen role in shaping coastal ecosystems. These organisms help stabilize shorelines, filter water and support biodiversity, making them foundational to coastal health. Yet they are increasingly threatened by ocean acidification and expanding populations of mobile shell-crushing predators.

Air pollution does not have to exceed federal limits to potentially harm human health, according to a new published study from the University of Mississippi.

Florida State University research published in Science Advances demonstrates a new framework for predicting the motion of kilometer-scale underwater waves that complicate satellite readings of the ocean.

A Dartmouth College study is the first to map the interplay of personal choice and social networks that has led to the United States being one of the world's most heavily armed countries, with 120 firearms for every 100 people. The researchers describe in Science Advances how individual incentives to buy firearms can lead to a phenomenon they call "overarming." In an overarmed society, the collective cost of firearm ownership outweighs the individual benefits of possessing a gun.

States with restrictive abortion policies saw slower growth in the proportion of female medical school applicants following the 2022 reversal of Roe v. Wade, according to a new study published in the open-access journal PLOS Global Public Health by Amrit Kirpalani of Western University, Canada, and colleagues.

A major new study of more than 115,000 young people suggests teenage well-being may finally be recovering after years of concern over the long-term impact of the COVID-19 pandemic.

The first large-sized bovines grew to up to half a ton 4 million years ago in the European Early Pliocene, an early step toward our modern diversity of large-bodied buffalo and cattle, according to a study published June 3, 2026, in the open access journal PLOS One by Leonardo Sorbelli of the Leibniz Institute for Evolution and Biodiversity Science, Germany, and colleagues.

The extinction that ended the Age of Dinosaurs is best known for clearing the way for the Age of Mammals on land. Scientists have long suspected that the same catastrophe also transformed life in the seas, opening ecological space for the rise of modern marine fish faunas. Yet the timing and geography of that transition have remained uncertain because of the sparse fossil record.

A new study suggests that, for modern Japanese speakers, two traditional, patriarchal words for "husband" ("shujin," literally meaning "master") and "wife" ("kanai," "inside-the-house") may be losing their original meanings, though men in the study evaluated both traditional and neutral words for "husband" more positively than words for "wife."
