As interstellar comet 3I/ATLAS began moving away from the Sun in December 2025, astronomers took the opportunity to turn NASA’s powerful James Webb Space Telescope in its direction and capture detailed measurements of its chemical components. The comet was freshly warmed from its closest pass by the Sun, and its ancient ice had been converted […]
Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history.
Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history. Formed as fragments coalesced after a violent collision 155 million years ago, the asteroid was transformed by the […]
One well-done gas giant, coming right up! That’s the latest from researchers analyzing NASA’s James Webb Space Telescope’s observations of HD 80606 b, an exoplanet four times the mass of Jupiter with an extremely elliptical orbit that sweeps close by its Sun-like star. The research team is presenting their study and preliminary findings Tuesday at […]

Researchers using two of humanity’s most powerful observatories — NASA’s James Webb and Hubble Space Telescopes — have definitively shown that Terzan 5 is not a globular star cluster as it was once classified, offering new insight into how galaxies like our own form and evolve over time. A globular star cluster typically has only […]

Poor hygiene, unsafe food handling practices, and a reliance on untrained food handlers may be placing vulnerable patients at some psychiatric hospitals at risk of foodborne illnesses, according to researchers in South Africa.
A study from the University of the Western Cape (UWC) assessed food safety practices among 91 foodservice
The complex puzzle known as little red dots has become more complete since their initial discovery by NASA’s James Webb Space Telescope in 2022. Now a particular little red dot’s spectrum is helping connect many of the pieces. A team of astronomers led by Vasily Kokorev at the University of Texas at Austin identified the […]
A compact, multifrequency radar built by a team at NASA’s Jet Propulsion Laboratory will make it easier to collect information about dynamic cloud systems. Called CloudCube, this new instrument simultaneously probes the atmosphere with three radar signals, spanning 36 to 240 GHz, for optimized sensitivity to a wide range of water droplet and ice particle sizes.
Researchers have described how climate change could have an impact on Salmonella and antimicrobial resistance.
Scientists analyzed more than 236,700 Salmonella genomes from 139 countries or regions over the period 1940 to 2023. They selected annual mean temperatures and rain levels as indicators of climate change. Future
Which comes first, the galaxy or the black hole? We don’t know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble up surrounding material and merge over time to form more massive entities. But it’s hard […]

The Gates Foundation has called for proposals to create estimates of the global burden of diarrheal diseases, with a focus on children younger than 5 living in low- and middle-income countries (LMICs).
The Foundation, previously called the Bill and Melinda Gates Foundation, wants to support efforts that inform the overall
NASA’s TESS has released its most complete view of the starry sky to date
A team of researchers demonstrated NASA and IBM’s open-source Prithvi Geospatial artificial intelligence foundation model aboard two in-orbit platforms.
After a recent count, NASA Citizen Science is proud to report that more than 650 people who have volunteered to participate in NASA citizen science projects have co-authored peer-reviewed research papers with scientists on those project teams. These volunteers made incredible contributions like: And all of them saw their passion and dedication translated into lasting […]

STEC was culture-confirmed in three samples and Salmonella was found once
Evidence shows that exposure is often linked to eating contaminated freshwater fish and handling practices along the food chain.
A review of food safety culture surveys has revealed significant diversity and notable gaps in validation practices.
Scientists said the reliable measurement of food safety culture is crucial to identify the strengths and weaknesses of companies in food safety performance, enabling them to aim for continuous improvement.
On every crewed mission, NASA packs pouches of a potentially life-saving liquid in its cargo, known as IV (or intravenous) fluid. A simple mix of sodium chloride and purified water, it can treat up to 30% of medical conditions in flight, resolving things like dehydration, burns, and more. Crewed missions beyond low Earth orbit into […]
Researchers are studying the impact nanoplastics have on Salmonella and have found they cause the pathogen to become more virulent.
The researchers at the University of Illinois Urbana-Champaign are particularly looking at Salmonella on plastic used in packaging for ground turkey.
Principal Investigator(s): Overview: Veg-06 studies how plants and beneficial bacteria work together in microgravity. Some plants, like beans and peas, partner with specific bacteria to pull nitrogen from the air and convert it into a form that plants can use for growth. The investigation also examines changes in lignin, the tough material that helps plants […]

Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published Monday in The Astrophysical Journal. Unlike in the new movie “Project Hail Mary,” this quieting […]

Rising temperatures and heatwaves are expected to have a major impact on serious Salmonella infections, according to scientists.
A new report from the Centers for Disease Control and Prevention shows that extensively drug resistant Shigella infections are increasing.
The research, published in the CDC's Morbidity and Mortality Weekly Report, covered a sample of Shigella infections from 2011 through 2023. Shigella is transmitted via contaminated food or
