NewsNew clues to hepatitis B species restriction could help build a novel model for studying infection and testing therapies
For decades, it was thought that the barrier to creating a workable mouse model for hepatitis B is an inability for the virus to gain a genetic foothold in the mouse due to its unique type of DNA. Now researchers have discovered that the problem is something different altogether—likely a misstep in the entry process.

NewsPioneering virologist Bernard Roizman dies at 96
Bernard Roizman, ScD, world-leading expert on herpes simplex virus (HSV) and Joseph Regenstein Distinguished Service Professor Emeritus of Microbiology and Molecular Genetics and Cell Biology at The University of Chicago, died on April 13, 2026, at the age of 96.

NewsIBS treatment response predicted by gut microbiome in new study
Researchers investigating irritable bowel syndrome with diarrhea observed distinct characteristics of patients’ gut microbiomes that predicted whether they responded to the low FODMAP diet or rifaximin — or did not respond to treatment.

NewsResearchers disable antimicrobial resistance in cystic fibrosis-associated bacteria
A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise sensitive strains.

NewsStudy shows links between Alzheimer’s and gut health can lead to prevention
Researchers analysed more than 120 everyday factors, including diet, medical history, gut bacteria, and lifestyle, to identify which of them are most strongly associated with Alzheimer’s risk. People who had their appendix removed showed substantially elevated Alzheimer’s risk.

NewsIs asphalt bad for our health? And can algae help?
Scientists studying how asphalt emissions impact respiratory health are also working on less toxic, lower-emitting asphalt formulations. One project involves growing a strain of algae that could reduce VOC emissions using wastewater from a treatment plant.

NewsRising measles cases highlight gaps in vaccination coverage and public health system vulnerabilities
The Global Virus Network (GVN) is closely monitoring a significant resurgence of measles in the United States and globally, reflecting a growing vulnerability in public health systems.

NewsCDI breakthroughs lead to new drug development deal for deadly NTM bacteria
Scientists have developed new compounds against non-tuberculous mycobacteria which are now the subject of a new collaboration and license agreement with the Switzerland-based and publicly listed BioVersys AG.

NewsEarly immune responses linked to protective HIV antibodies
In a new study of broadly neutralizing antibodies and their potential for an HIV vaccine, researchers analyzed fragments of cell-free RNA and DNA circulating in the blood. This makes it possible to track immune responses, viral genetic variation, and other microbes from the same blood sample.

NewsMillions suffering needlessly with curable hepatitis C, new analysis reveals
Millions of Americans are still battling potentially deadly hepatitis C even though they could be cured with antiviral drugs they are not receiving, a new analysis reveals.

NewsHas life-saving HIV therapy contributed to increased rates of a sexually transmitted disease?
A study has uncovered an unintended consequence of a major medical breakthrough: while the availability of HIV treatments in the late 1990s dramatically improved survival, they also contributed to a resurgence in syphilis, a sexually transmitted infection.

NewsConnected habitats help wildlife fight disease, strengthen protective microbes
Maintaining connections between natural habitats may support beneficial microbes that help wildlife defend against disease. A new study found that amphibians in connected natural forests and aquatic habitats were more likely to host beneficial skin microbes that inhibit a deadly fungal pathogen.

NewsSome resilient fungi might survive the long voyage to Mars
Researchers recently identified fungi in samples from spacecraft-associated environments, including cleanrooms. Conidia grown from those fungi survived after exposure to simulations of the harsh conditions of Mars and space travel.

NewsScientists map how HIV hijacks human cells—and how cells can fight back
Scientists have opened a new door to understanding HIV by creating the first comprehensive genetic roadmap of how the virus interacts with real human cells. They identified a multitude of hidden players in HIV infection, human proteins that either help the virus thrive or work to stop it.

NewsSevere childhood malaria linked to cognitive impairment later in life
New findings suggest children who survive cases of cerebral malaria and severe malarial anemia experience cognitive and academic impairment that persists into adolescence.

NewsStudying two very different viruses helps to develop new strategies
When the SARS-CoV-2 pandemic began, virologist Theodora Hatziioannou, in conjunction with Paul Bieniasz brought her HIV-honed skills and tools to this new global threat, which made it easier and faster for researchers to gain insights into the virus and test antibodies for potential therapeutic candidates in real time.

NewsResearchers come up with novel strategies for coral restoration
Scientists have discovered a new way to help lab-grown baby corals survive through the early life stage. If young mountainous star corals are grown on cement tiles formulated with sodium carbonate, which raises the alkalinity of the water, they survive much better than the average lab-grown corals.

NewsScientists probe how neurons sense bacteria in the gut
Neural interaction with bacteria, e.g. in the gut microbiome, has important effects on brains of animals from worms to people. A new study investigates how neurons sense bacteria by revealing, in nematodes, the bacterial signals that a key neuron detects.

NewsGut bacteria predict skin cancer recurrence, but only when matched for ‘microbial fingerprint’
The specific mix of bacteria living in a person’s gut can predict the chances that melanoma will recur after surgery and immunotherapy, which helps immune cells target cancer cells, according to a new study.
