NewsSoil bacteria and minerals form a natural ‘battery’ that breaks down antibiotics in the dark
Researchers have unveiled a surprising new way that soil microbes can use sunlight energy. The team developed a “bio-photovoltage soil-microbe battery” that can capture, store, and release solar energy to power the breakdown of antibiotic pollutants in the dark.

NewsMicrobiome and nanoparticle discoveries hold promise for treating gut pain
In an effort to develop targeted treatments for gut pain, scientists have discovered a new enzyme in gut bacteria and are using nanoparticles to deliver drugs inside cells. PAR2, a receptor involved in pain signaling, is activated by certain enzymes called proteases.

NewsResearchers find key to stopping deadly infection
New research has identified a key step that enables rotavirus to infect cells. The researchers found that disabling the process in tissue culture and in mice prevented infection.

NewsNew vaccine shows promise against typhoid and invasive salmonella in first human trial
Researchers have completed a successful Phase 1 clinical trial of a novel vaccine designed to protect against both typhoid fever and invasive non-typhoidal Salmonella–two major causes of illness and death among children in sub-Saharan Africa.

NewsProfessor awarded $3.9 million to fight deadly parasites that threaten children and immunocompromised adults
A multi-institutional team will develop effective drugs that are urgently needed to manage cryptosporidiosis in young children, immunocompromised adults and as a countermeasure to epidemic outbreaks.

NewsTrailblazing Young Scientists honored with $250,000 prizes at Blavatnik National Awards Gala
Three of America’s most promising young scientists were awarded top honors at the 2025 Blavatnik National Awards for Young Scientists, one of the country’s most significant prizes for early-career researchers. The Life Sciences Laureate was Philip J. Kranzusch, Harvard Medical School (Microbiology).

NewsNew study reveals where HIV hides in different parts of the body
A new study reveals that HIV cloaks itself in the DNA of infected cells using unique DNA patterns in the brain, blood and parts of the digestive tract. For example, in the brain, the virus avoids genes and hides in less active parts of the DNA.

NewsYeast proteins reveal the secrets of drought resistance
A new study in Cell Systems helps explain how organisms can come back from desiccation (the removal of water or moisture) while others fail by looking at the cell’s proteins. In the first survey of its kind, a team of researchers profiled thousands of proteins at once for their ability to survive dehydration and rehydration.

NewsScientists blaze new path to fighting viral diseases
Scientists have identified a potential new drug against the virus that causes COVID-19 - and devised a powerful new platform for finding medicines to fight many types of infectious diseases. Compound 6, led SARS-CoV-2 viral proteins to misfold, malfunction, and ultimately, be destroyed and removed by cells, in lab tests.

NewsResearchers wake up microbes trapped in permafrost for thousands of years
In a new study, a team of geologists and biologists resurrected ancient microbes that had been trapped in ice—in some cases for around 40,000 years.

NewsMarine heatwaves have hidden impacts on ocean food webs and carbon cycling
A new study analyzing data from robotic floats and plankton records reveals how marine heatwaves reshape ocean food webs and slow transport of carbon to the deep sea.

NewsResearch reveals fetuses exposed to Zika virus have long-term immune challenges
Researchers discovered that when a pregnant mother is infected with Zika virus, the resulting inflammatory response in the placenta permanently changes how the offspring’s immune system develops - even if the infection is mild or asymptomatic in the mother.

NewsThe essential role of the urban tree microbiome: A key to city health
Researchers studied the difference in microbial communities of street trees and non-urban forest trees. By analyzing fungal and bacterial diversity, tree size, and soil properties, their research shows the impacts of urban environmental stressors upon city tree microbiomes.

NewsLong Ebola: Sudan virus can persist in survivors for months, study shows
More than half of survivors of the Sudan Ebola virus still suffer serious health problems two years post-infection and the virus can persist in semen and breast milk for months after recovery, according to the first study examining the virus’s long-term effects.
-
NewsScientists explore how viruses replicate and infect
Herpes viruses cultivated using one kind of host cell – known as a producer cell – exhibited differences from the same virus cultivated with a different producer cell.

NewsResearchers deconstruct chikungunya outbreaks to improve prediction and vaccine development
Researchers analyzed more than 80 outbreaks of chikungunya virus to improve prediction of future outbreaks and inform vaccine trial development.

NewsThe RESTART trial: a drug to block a toxic HIV molecule
What if the presence of a well-known but misunderstood viral protein explains why some people living with HIV (PLWH) never recover their health, even with antiretroviral treatment? Researchers will explore this in a groundbreaking clinical trial this fall.

NewsSome human GII.4 norovirus are better than others at infecting cells; researchers have found out why
A study reveals that human GII.4 noroviruses have evolved a uniquely potent entry mechanism with clear strain-specific differences. The findings open new possibilities for identifying the elusive human norovirus receptor as well as developing vaccines and treatments.

NewsNew antibiotic targets IBD — and AI predicted how it would work before scientists could prove it
The new antibiotic, enterololin, attacks and kills only a specific group of disease-causing bugs, which includes the type of E. coli that drives Crohn’s disease. It is a promising new treatment option for people affected by Crohn’s and other IBD-related conditions.

NewsAncient plankton hint at steadier future for ocean life
A team of scientists has uncovered a rare isotope in microscopic fossils, offering fresh evidence that ocean ecosystems may be more resilient than once feared. They analyzed nitrogen isotopes preserved in the shells of tiny plankton called foraminifera.
