NewsResearchers develop new inhalable treatment for TB
Researchers have developed an inhalable, immunomodulating, biocompatible nanoparticle system encapsulating rifampin, one of the most important TB drugs.
-
NewsResearchers solve mystery behind rare clotting after adenoviral vaccines or natural adenovirus infection
Scientists have uncovered why a small number of people developed dangerous blood clots after either receiving certain COVID‑19 vaccines or experiencing a natural adenovirus infection - the answer lies in an unexpected case of misdirected targeting by the immune system.

NewsVirus-based therapy boosts anti-cancer immune responses to brain cancer
A study has shown that a single injection of an oncolytic virus—a genetically modified virus that selectively infects and destroys cancer cells—can recruit immune cells to penetrate and persist deep within brain tumors.
-
NewsHow food shortages reprogram the immune system’s response to infection
When food is scarce, stress hormones direct the immune system to operate in “low power” mode to preserve immune function while conserving energy. This reconfiguration is crucial to combating infections amid food insecurity.

NewsAvian malaria widespread across Hawaiʻi bird communities, new study finds
A new study shows that avian malaria can be transmitted by nearly all forest bird species in Hawaiʻi, helping explain why the disease is present almost everywhere mosquitoes are found across the islands.
-
NewsBacterial hitchhikers can give their hosts super strength
Molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups. The study introduces a previously unknown avenue through which bacterial infections can become more difficult to treat.
-
NewsShorter treatment regimens are safe options for preventing active tuberculosis
A study comparing one- and three-month antibiotic treatments to prevent active tuberculosis (TB) finds that a high percentage of patients successfully completed both regimens and suffered few adverse side effects.
-
NewsUS study finds declining perception of safety of COVID-19, flu, and MMR vaccines
A sizable majority of Americans think the three vaccines that combat potentially deadly illnesses flu, Covid-19 and measles are safe to take, although perceptions of the safety of all three vaccines showed a statistically significant drop over the past three years.

NewsResearchers identify strategies for preventing the most infectious strains of S. aureus in the NICU
A new study has identified which strains of Staphylococcus aureus – commonly known as staph – are commonly transmitted in neonatal intensive care units and which specific strains are most likely to cause invasive and serious infections.
-
NewsResearchers rebuild microscopic circadian clock that can control genes
Researchers have solved how the circadian clocks within microscopic bacteria are able to precisely control when different genes are turned on and off during the 24-hour cycle.
-
NewsScientists create ‘smart underwear’ to measure human flatulence
Scientists have created Smart Underwear, the first wearable device designed to measure human flatulence. The device helps scientists revisit long-standing assumptions about how often people actually fart. It also opens a new window into measuring gut microbial metabolism in everyday life.
-
NewsLong COVID linked to Alzheimer’s disease mechanisms
The increased size of, and lesser blood supply to, a key brain structure in patients with Long COVID tracks with known blood markers of Alzheimer’s disease and greater levels of dementia, a new study finds.
-
NewsNew AI model improves accuracy of food contamination detection
Researchers have significantly enhanced an artificial intelligence tool used to rapidly detect bacterial contamination in food by eliminating misclassifications of food debris that looks like bacteria. Current methods often require specialized expertise and are time consuming — taking several days to a week.
-
NewsAntibiotic-resistant bacteria found in many healthy birthing mothers and their newborns
A recent study found gut bacteria resistant to common antibiotics in a sizable percentage of healthy birthing mothers and their newborns. In this study, 38% of bacterial strains resistant to ceftriaxone transmitted from mother to infant were E. coli.
-
NewsTechnology transfer for Corallopyronin A successfully completed with Phyton Biotech
Phyton Biotech has successfully transferred the manufacturing process for the microbial production of Corallopyronin A (CorA). CorA is a novel anti-infective agent with the potential to address neglected tropical diseases.
-
NewsTexas-grown cabbage meets global tradition in kimchi research
Researchers are turning Texan produce into kimchi as part of a study that links fermentation science, food safety and new market opportunities for U.S. farmers. The research examines how Texas-grown cabbage and other leafy greens perform during kimchi fermentation.
-
NewsBee bandits: ecologists study mutualistic plant-pollinator-microbe interactions
Researchers studying nectar-robbing behavior in bumble bees suspect other organisms beyond plants and pollinators may be aiding and abetting pollinators in nectar-robbing behavior.
-
NewsWhat drives food allergies? New study pinpoints early-life factors that raise risk - including microbiome
A new study involving 2.8 million children around the world has revealed the most important early-life factors that influence whether a child becomes allergic to food. Genetics alone cannot fully explain food allergy trends, pointing to interactions between genes, skin health, the microbiome, and environmental exposures.

NewsScientists uncover link between influenza and heart disease
Researchers have identified a cellular mechanism linking infections from influenza A viruses (IAVs) to cardiovascular disease, providing critical insights on how influenza can damage the heart and increase the risk of a heart attack or other major cardiovascular event.

NewsH5N1 causes die-off of Antarctic skuas
More than 50 skuas in Antarctica died from the high pathogenicity avian influenza virus H5N1 in the summers of 2023 and 2024, marking the first documented die-off of wildlife from the virus on the continent.
