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.

NewsColorectal cancer risk linked to gut microbiome alterations
A study finds that more than a decade after removal of an adenoma from the colon, the gut microbiome still partly resembles that observed in colorectal cancer (CRC).

NewsNew study finds neighborhood-level sampling could close equity gap in wastewater disease surveillance
Researchers working with New York State’s wastewater surveillance network found that while the system does a reasonably fair job of including vulnerable populations, it struggles in larger populations when an outbreak is starting, which is when it matters most.

NewsLong Covid burden continues to grow, doubling current surveillance estimates, multi-hospital study shows
Investigators using a novel AI algorithm to comb through medical records of patients with COVID-19 in U.S. hospitals, found around one in six developed long COVID. These rates are twofold higher than current estimates.

NewsCommon illnesses, not hantavirus, pose greatest cruise and travel risk
Travelers booked on cruises this summer, or considering booking, shouldn’t change their plans out of fear of hantavirus, one researcher says. They should be aware of more common viral illnesses that occur in cruise settings such as norovirus, seasonal respiratory viruses, COVID-19 and influenza.

NewsHeart health may have impacted the risk of severe COVID-19 infection during the pandemic
Adults with highest heart health scores at the beginning of the pandemic were nearly half as likely to be hospitalized or die from COVID-19 when compared to those with the lowest scores, according to new research.

NewsDog daycare leptospirosis outbreak in Los Angeles reveals broader public health risks
A 2021 outbreak of leptospirosis that sickened more than 200 dogs in Los Angeles County reveals critical gaps in vaccination practices and raises broader concerns about the spread of the disease between animals and people.

NewsScientists determine how mysterious acids give bacteria their shape
Researchers have discovered how acids on the surface of bacteria give these microscopic organisms their characteristic “rod” shape—by keeping an enzyme at bay that would otherwise turn the cylindrical cells into shape-shifting blobs.

NewsScientists identify nearly two dozen antiviral compounds that could treat Ebola virus
Recent advances in artificial intelligence have enabled scientists to identify nearly two dozen antiviral compounds that could potentially treat a rare species of Ebola virus (Bundibugyo virus) currently affecting the Democratic Republic of Congo.

NewsStudies point to new way to fight potentially deadly Valley Fever
To better understand why Valley Fever spreads in some individuals, researchers found that patients with severe illness had an abnormal immune response. In some cases, the immune system was overactive; in other cases it was underactive.

NewsNew urine test for microbial metabolites offers simple way to screen for autism in children
Scientists have developed a new screening tool to test urine for 17 microbial metabolites in children ages 2 to 11 years. By measuring these compounds in urine, they discovered that they could distinguish children with autism from typically developing children in their study groups with high accuracy.

NewsInternational award honors microbiology researchers for diatom research
Two microbiology researchers from the University of Tennessee, Knoxville, are being honored with an international award that recognizes their insights into aquatic microbes that are vital to Earth’s ecosystems.
