NewsHow bacteria may promote breast cancer
Researchers have discovered how certain pathogenic bacteria in gut and breast tissue can promote breast cancer development and progression by hijacking a key metabolic enzyme known as spermine oxidase (SMOX).
-
NewsScientists develop first-of-its-kind antibody to block Epstein Barr virus
Using mice with human antibody genes, scientists have developed new genetically human monoclonal antibodies that prevent two key antigens on the surface of the Epstein Barr virus (EBV) from binding to and entering human immune cells.

NewsStrategic changes in water treatment could prevent disease outbreaks
A breakthrough new study shows how strategic changes in water treatment effectively treated a deadly outbreak of Legionnaires’ Disease. For the first time, the study provides evidence of an outbreak being stopped by introducing disinfection to previously untreated groundwater.
-
NewsNew biosensor offers early warning system for disease
Researchers have developed a tissue-adhesive sensor for real-time oral health monitoring to combat long-term issues such as gum disease and tooth loss.
-
NewsImmunity against common virus leveraged against pancreatic cancer
Researchers have discovered a promising new treatment approach for pancreatic cancer. The approach leverages the body’s natural immune response to cytomegalovirus (CMV), a common but typically harmless virus that most people are infected with at some point in their lives.

NewsBeneficial bacterium deployed to protect turfgrass from fungal foes
A novel strain of Bacillus subtilis helps a variety of plants resist soil‑borne diseases, retain moisture and develop stronger root‑to‑shoot growth. New findings on the effect of UD1022 on dollar spot disease suggests intriguing implications for manufacturing of biological treatments for the fungal disease.

NewsRich medieval Danes bought graves ‘closer to God’ despite leprosy stigma, archaeologists find
Researchers used gravesites to investigate social exclusion based on illness, by studying whether people with leprosy or tuberculosis were kept out of the higher-status areas. Unexpectedly, they found that people who were ill with stigmatized diseases were buried just as prominently as their peers.

NewsNo association between mRNA COVID-19 vaccination during pregnancy and autism in children, new research shows
The mRNA COVID-19 vaccine is not associated with autism or other neurodevelopmental problems in children whose mothers received the vaccine immediately before or during pregnancy, according to new research.
-
NewsProposals for exploring viruses and skin as the next experimental quantum frontiers share US$30,000 science award
Viruses exist at the boundary between living and non-living matter, while skin is a living interface between physics and biology, making them perfect—but until now overlooked—arenas for testing the interplay between quantum physics, biology and life.

NewsBasic research on Listeria bacteria leads to unique cancer therapy
After nearly 40 years of research on how Listeria bacteria manipulate our cells and battle our immune system to cause listeriosis, researchers have discovered a way to turn the bacteria into a potent booster of the immune system — and a potential weapon against cancer.
-
NewsChildren with Crohn’s have distinct gut bacteria from kids with other digestive disorders
Researchers have found a “microbial signature” of pediatric Crohn’s disease that differs from the makeup of gut bacteria in children with other gastrointestinal conditions, with Crohn’s patients harboring more pro-inflammatory bacteria and less protective bacteria.
-
NewsManagement practices can enhance soil microbiome functions in plant defense
Researchers analyzed surveys and soil samples from 85 organic farmers in New York to investigate the interaction between beliefs, management practices, and soil microbiome functions.
-
NewsBack from blight: Genomics offers a faster path to restoring the American chestnut
After more than a century of devastation from deadly blight, the iconic American chestnut tree could be brought back from the brink of extinction thanks to novel genomic tools and carefully bred hybrids, a new study finds.
-
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.
