Gene editing could replace a lifetime of medication, but there's a catch
A single gene-editing treatment could someday protect against heart disease, high cholesterol, and other common conditions for decades, potentially replacing lifelong medications. But scientists warn that permanently altering genes introduces risks that could take years to
Scientists trick cancer cells into making the drugs that kill them
Scientists have developed a promising new cancer-fighting strategy that uses carbon monoxide naturally produced by tumor cells to manufacture powerful drugs inside the cancer cells themselves. Early laboratory experiments suggest the technique could selectively attack cancer
Researchers develop sensors for continuous corn growth monitoring
When is the best time to apply nitrogen? What plant response was there to fertilizer or any number of other treatments? There is a general answer to those questions now, but what if plant breeders and agronomists could download data from continuously monitored cornstalks and
How anxiety over climate change affects college students
College undergraduates are anxious about climate change, with many feeling powerless and frustrated about Earth's future, yet resources to help students cope are in short supply, according to new interdisciplinary University of Utah research. The sentiment isn't limited to
A hidden star is plowing through Betelgeuse’s atmosphere, new evidence suggests
Something mysterious is disturbing Betelgeuse, and astronomers believe they have identified the culprit: a hidden companion star called Siwarha. New radio observations reveal that the smaller star may be plowing through Betelgeuse’s enormous atmosphere, creating disturbances

North Atlantic's 'cold blob' may contain climate nuance
Climate observers have long tied the strength of a major ocean current to water temperatures in the so-called "cold blob" in the North Atlantic Ocean. The 965,000-square-mile (2.5 million square kilometers) area south and southeast of Greenland cooled by as much as 1.8 degrees
How the nasal microbiome can help potentially harmful bacteria thrive
Our noses are home to many different species of bacteria living side by side. One of them may be S. aureus. Many people carry this bacterium without knowing it, although it can cause serious infections. Why S. aureus colonizes some people persistently but not others remains

US midterm elections: Younger politicians could strengthen trust in democracy
It's no secret that American politics is dominated by older politicians. When 81-year-old Joe Biden withdrew from the 2024 presidential race amid concerns about his age, it was the then-78-year-old Donald Trump who ultimately entered the White House. The median age in the House
Using vibrations to reveal what lies beneath other planets' surfaces
Modern space exploration hasn't quite reached "Star Trek" levels of boldly going where no one has gone before. But if, like the denizens of the USS Enterprise, astronauts one day want to land on an uncharted planet, they'd first want to know what's on—and under—the surface.

Finding a signal from an extraterrestrial civilization takes more than just pointing a telescope in the right direction. We may also need to listen at exactly the right time.
Stone Age hunters in northern Europe may have used poison arrows to hunt big prey
Autumn walks in Britain are glorious, as the foliage changes color and cool, crisp air begins to bite. However, some of these European trees hide a much darker secret. For example, the yew tree's lovely red arils—the cup-shaped coverings around the seeds—carry toxins that may
