NewsWhat is the link between HIV and chronic pain?
A mouse study reveals a mechanism linking HIV to chronic pain. Targeting each of the molecular players in this mechanism alleviates pain and may hold treatment promise for HIV-associated pain, though more work is needed.

NewsOne simple trick makes zebrafish a better model for microbiome research
A new advance in animal husbandry involving a popular aquarium fish should speed the pace of discovery in laboratory studies of host-microbe interactions, researchers report.

NewsBehind the diagnosis: How laboratory testing guided a complex histoplasmosis case
A diagnosis of histoplasmosis forced a teenager with juvenile arthritis onto an uncertain path, one defined by months of treatment, recovery, and a long-term course of antifungal therapy expected to last up to three years. Histoplasma capsulatum, a dimorphic fungus that causes histoplasmosis, found its way into her lungs.

NewsPrecigen presents new long-term durability data for PAPZIMEOS, recently granted seven-year market exclusivity
Precigen, Inc. has announced updated long-term follow-up data from the pivotal study of PAPZIMEOS™ (zopapogene imadenovec-drba) for the treatment of adults with recurrent respiratory papillomatosis (RRP).

NewsNew analysis confirms benefits of childhood flu vaccines
Pediatric flu vaccines significantly reduce the number of childhood cases of influenza, new research confirms. The findings show that for every 100 children vaccinated, between nine and 14 fewer children catch the flu.

NewsNew study suggests fish gut microbe helps regulate ocean health
New research reveals a potential link between the gut microbes of a fish and global ocean processes, offering new insight into how marine ecosystems help regulate ocean chemistry and the marine carbon cycle.

NewsResearch shows plants such as canola, tomatoes and rice reduce iron uptake when stressed by drought
New research has found that plants, ranging from canola to rice to tomatoes, actively shut down their own ability to take up iron when they experience drought. The study questions whether plants send out a ‘cry for help’ when they are stressed by drought to recruit beneficial soil microbes in their roots.

NewsResearchers discover tick protein that may block disease transmission
Researchers have found that ticks produce an exosomal glycine-rich protein that plays a vital role in helping ticks feed and transmit viruses. When they used genetic tools to silence the gene responsible for this protein, ticks lacking the protein struggled to feed effectively and showed reduced body weight after feeding.

NewsProtective soybean seed fungicide treatment may not increase profitability
Researchers analyzed how seed treatments affect yield and profitability in soybean farms in the Midwest and found that yield gains were modest and often did not offset the added cost of the treatment. Additionally, financial benefit was likely only when seed treatment costs were low and soybean prices were high.

NewsHealth researchers call for support to develop pandemic prevention
The Vanderbilt Center for Antibody Therapeutics has received large-scale government grants and contracts to fund the discovery of human antiviral antibodies. The problem is the next step — finding corporate partners to develop the antibodies through human testing.

NewsSoil scientist awarded $1.6 million NSF grant to study ‘living skin’ of arid ecosystems
A soil scientist has received a $1.6 million, five-year grant from the U.S. National Science Foundation (NSF) to fund her team’s study of how increasing temperature fluctuations impact the biocrust microbiome — the complex, thin-layer microbe community that stabilizes soil, fixes nitrogen and drives nutrient cycling in drylands.

NewsResearchers aim to improve access to high-quality research and biomanufacturing tools in resource-limited settings
Researchers have demonstrated the effectiveness of a suite of low-cost, portable biotechnology tools designed to improve access to laboratory research and diagnostics in resource-limited settings.

NewsResearchers transfer nitrogen-harvesting genes into new bacteria
New research has identified a key cluster of genes that can be moved from rhizobia bacteria that harvest nitrogen into bacteria that don’t — raising the possibility that microbes that dwell in cereal crops could eventually be engineered to atmospherically harvest nitrogen as well.

NewsWhy antibiotics fail against a common dental implant disease
A study of peri-implantitis found that bacteria corrode implants, causing them to shed microscopic titanium particles into the surrounding tissue. Those particles hijack the immune cells sent to clear the infection and lock them into a state of inflammation that destroys the jawbone they are supposed to protect.

NewsExperimental HIV vaccine achieves a long-sought goal
In a first for the field, all non-human primates given a new series of vaccines generated antibodies capable of fighting multiple strains of HIV. It brings researchers closer to a vaccine effective against the vast diversity of HIV strains circulating worldwide.

NewsScientists validate a link between autoimmunity in a subset of people with long COVID
A research team has demonstrated that autoimmunity, where the body’s immune system attacks its own tissues, is responsible for the often-debilitating and confounding symptoms of long COVID in a subset of people.

NewsUnilever investing $270m in Global Innovation Centre in New Haven, Connecticut
Unilever has unveiled plans to develop a new Global Innovation Centre in New Haven, Connecticut, opening by spring 2029. The centre will be a leading hub for the company’s research and development for its personal care, beauty and wellbeing businesses in the U.S. and globally.

NewsFungal surges marked Cretaceous mass extinction that ended age of dinosaurs
The asteroid impact thought to have wiped out the dinosaurs 66 million years ago was followed by surges of fungi in North America. These are the first findings to provide direct evidence that this post-asteroid fungal bloom may have been a global event.

NewsNew model shows how gut microbes help shape how many calories you absorb from food
A new mathematical model follows food through the digestive tract, estimating what the body absorbs directly, what reaches the colon and how gut microbes help process the remaining material into products that are either absorbed or excreted.

NewsResearchers may now understand why chikungunya virus infections turn chronic
About half of people infected with chikungunya virus will progress to a chronic form of the disease. A new study finds that chikungunya virus persists in joint-associated macrophages, a specialized type of white blood cell that helps the body defend against pathogens.
