The study analyzed medical records from more than 6,800 people diagnosed with colon cancer across University of California Health facilities. Patients who were taking GLP-1 medications were less than half as likely to die within five years compared to those not using the drugs (15.5% versus 37.1%). This striking difference points to a potentially powerful new use for drugs that are already transforming diabetes and obesity treatment.

The research was led by Raphael Cuomo, Ph.D., an associate professor in the Department of Anesthesiology at UC San Diego School of Medicine and a member of the UC San Diego Moores Cancer Center. His team used the University of California Health Data Warehouse to review outcomes across the state’s academic medical centers.

After accounting for important factors such as age, body mass index (BMI), cancer severity, and other health conditions, the team found that people taking GLP-1 drugs still had a significantly lower risk of death. This consistency suggests the protective benefit of GLP-1 therapy may be independent of other medical or lifestyle variables.

Why GLP-1 Drugs Might Protect Against Cancer

The benefit appeared strongest in patients with obesity (BMI over 35). This finding hints that GLP-1 drugs may help offset some of the inflammation and metabolic stress that can make cancer harder to treat.

Scientists are exploring several possible explanations for this effect. GLP-1 receptor agonists are known to lower inflammation throughout the body, enhance insulin sensitivity, and promote weight loss — all factors that can influence cancer growth and progression. Experimental studies in laboratories also indicate that GLP-1 drugs may directly inhibit the growth of tumor cells, encourage cancer cell death, and alter the surrounding environment within tumors to make them less supportive of disease spread.

However, researchers caution that it is still unclear whether the lower death rate seen in this study reflects a direct anti-cancer action or an indirect result of improved overall metabolic health.

Next Steps: Clinical Trials Needed

Dr. Cuomo emphasized that the findings are observational, meaning they do not yet prove that GLP-1 drugs directly improve cancer outcomes. These results highlight an urgent need for clinical trials to test whether GLP-1 medications can actually enhance cancer survival, particularly among patients with obesity-related cancers.

The study was published in Cancer Investigation on November 11, 2025.

Using the James Webb Space Telescope’s (JWST) Mid-Infrared Instrument (MIRI), the research team identified five carbon-based compounds in the Large Magellanic Cloud, our closest neighboring galaxy. The study, led by University of Maryland and NASA scientist Marta Sewilo, was published in the Astrophysical Journal Letters on October 20, 2025.

Detecting Life’s Chemical Ingredients in Alien Ice

Sewilo’s group found five complex organic molecules (COMs) within the ice surrounding the young protostar. These included methanol and ethanol (both types of alcohol), methyl formate and acetaldehyde (industrial chemicals on Earth), and acetic acid (the main ingredient in vinegar). One of the compounds, acetic acid, had never before been definitively observed in space ice, while the others — ethanol, methyl formate, and acetaldehyde — were detected in ices outside the Milky Way for the first time.

The team also spotted signs of glycolaldehyde, a sugar-related molecule linked to RNA formation, though further analysis is required to confirm it.

JWST’s Sharp Vision Opens a New Window on Cosmic Chemistry

“It’s all thanks to JWST’s exceptional sensitivity combined with high angular resolution that we’re able to detect these faint spectral features associated with ices around such a distant protostar,” Sewilo said. “The spectral resolution of JWST is sufficiently high to allow for reliable identifications.”

Before the Webb telescope, methanol was the only complex organic molecule ever confirmed in ice around protostars — even within our own galaxy. According to Sewilo, the extraordinary precision of the new data allowed her team to extract an unprecedented amount of information from a single spectrum.

A Harsh Galaxy as a Laboratory for Life’s Origins

The discovery is especially striking because of where the molecules were found. The Large Magellanic Cloud, located about 160,000 light-years from Earth, is an ideal environment for studying how stars form in conditions resembling those of the early universe. This small galaxy has only about one-third to one-half the heavy elements (those with atomic numbers greater than helium) of our solar system and endures far more intense ultraviolet radiation.

“The low metallicity environment, meaning the reduced abundance of elements heavier than hydrogen and helium, is interesting because it’s similar to galaxies at earlier cosmological epochs,” Sewilo explained. “What we learn in the Large Magellanic Cloud, we can apply to understanding these more distant galaxies from when the universe was much younger. The harsh conditions tell us more about how complex organic chemistry can occur in these primitive environments where much fewer heavy elements like carbon, nitrogen and oxygen are available for chemical reactions.”

How Complex Molecules Form on Cosmic Dust

Study co-author Will Rocha of Leiden University in the Netherlands noted that COMs can form in both the gas phase and in icy layers coating interstellar dust grains. Once formed, these ices can later release their molecules back into the gas. Methanol and methyl formate had already been observed in the gas phase within the Large Magellanic Cloud, but this is the first evidence that such molecules are also forming in the solid ice itself.

“Our detection of COMs in ices supports these results,” Rocha said. “The detection of icy COMs in the Large Magellanic Cloud provides evidence that these reactions can produce them effectively in a much harsher environment than in the solar neighborhood.”

Life’s Ingredients May Have Formed Early in the Universe

The presence of these complex molecules in a low-metallicity environment similar to those found in the early universe suggests that the building blocks of life may have begun forming much earlier — and in a wider range of conditions — than scientists once thought.

While this discovery does not prove that life exists elsewhere, it indicates that organic compounds can endure through the process of planetary formation and potentially be incorporated into young planets, creating conditions where life might one day emerge.

Expanding the Search for Cosmic Chemistry

Sewilo and her collaborators plan to extend their work by examining more protostars in both the Large and Small Magellanic Clouds to explore how widespread these molecules may be.

“We currently only have one source in the Large Magellanic Cloud and only four sources with detection of these complex organic molecules in ices in the Milky Way. We need larger samples from both to confirm our initial results that indicate differences in COM abundances between these two galaxies,” Sewilo said. “But with this discovery, we’ve made significant advancements in understanding how complex chemistry emerges in the universe and opening new possibilities for research into how life came to be.”

“Our analysis shows a unique planetary arrangement: two planets are transiting one star, and the third is transiting its companion star,” explains Sebastián Zúñiga-Fernández, a researcher at the University of Liège (ULiège) and first author of the paper. “This makes TOI-2267 the first binary system known to host transiting planets around both of its stars.”

A Compact and Unusual Double-Star System

TOI-2267 consists of two stars locked in a close orbital dance, forming what astronomers call a compact binary system. Such systems create gravitational forces that typically disrupt planet formation. Despite this, researchers have detected three Earth-sized planets in tight orbits, a surprising outcome that challenges long-held theories about where rocky worlds can exist.

“Our discovery breaks several records, as it is the most compact and coldest pair of stars with planets known, and it is also the first in which planets have been recorded transiting around both components,” says Francisco J. Pozuelos, a co-leader of the study and researcher at the Instituto de Astrofísica de Andalucía (IAA-CSIC).

Combining Space and Ground Observations

NASA’s TESS space telescope first provided the data leading to this discovery. Two of the planets were initially identified by astronomers at ULiège and IAA-CSIC using their custom software tool, SHERLOCK. This early detection prompted ground-based observations to confirm the findings.

The confirmation process required a major effort involving several observatories. Among the most important were the SPECULOOS and TRAPPIST telescopes operated by ULiège (PI: Michaël Gillon). Designed to detect small exoplanets around cool, dim stars, these robotic instruments were vital for verifying the planets and studying their characteristics in detail.

A Natural Testbed for Planet Formation

“Discovering three Earth-sized planets in such a compact binary system is a unique opportunity,” says Zúñiga-Fernández. “It allows us to test the limits of planet formation models in complex environments and to better understand the diversity of possible planetary architectures in our galaxy.”

Pozuelos adds, “This system is a true natural laboratory for understanding how rocky planets can emerge and survive under extreme dynamical conditions, where we previously thought their stability would be compromised.”

Looking Ahead to Future Exploration

The discovery opens up new questions about how planets form and persist in binary systems. Upcoming observations with the James Webb Space Telescope (JWST) and next-generation ground-based observatories could reveal more details, such as the planets’ masses, densities, and even their atmospheric compositions.

Beyond its scientific importance, the finding underscores the value of combining data from space-based observatories like TESS with precise ground-based instruments such as SPECULOOS and TRAPPIST. Together, they continue to expand our understanding of how planetary systems form and evolve across the galaxy.
