NewsScripps Research scientists awarded $2M to advance global disease surveillance
Two Gates Foundation grants will expand wastewater surveillance and AI-driven disease monitoring to support faster public health responses worldwide.

NewsScientists discover how algae colonized corals, jumpstarting the growth of the world’s reefs
A research team questioned why algae are able to thrive inside the cells of coral? The finding could lead to new insights into why algae and coral are failing to thrive symbiotically and suggest ways to reestablish the connection and save the world’s reefs.

NewsThe case for fewer antibiotics in joint replacement surgery
Infections are a leading cause of joint replacement failures, however a new study suggests prescription of an extended courses of antibiotics after patients leave the hospital may not be needed.

NewsMeet EcoBOT: The autonomous lab standardizing plant-microbe research
Berkeley Lab’s new “self-driving” laboratory, EcoBOT, automates complex plant experiments to eliminate human error, solve biology’s replication crisis, and accelerate bioenergy research.

NewsBreakthrough study could unlock key to more reliable truffle cultivation
A pioneering study has revealed that growing truffles depends not just on soil conditions, but on a complex underground ecosystem that the truffles may help to engineer themselves.

NewsWhat D.C.’s algal bloom reveals about a growing water threat
Environmental engineer Steven Chapra speaks out about cyanobacteria algal blooms in the newly renovated Lincoln Memorial Reflecting Pool, expanding on why harmful algal blooms are a growing concern, and what they may mean for freshwater ecosystems.

NewsBacteria can learn and form memories without a brain
Scientists have shown that bacteria can learn from past experiences, store memories across generations and adapt their behavior to changing environments.
-
NewsGrowing evidence that sugar substitutes disrupt gut health and metabolism
In a new review, researchers noted that artificial and other low-calorie sweeteners, compared to non-caloric controls such as water or placebo, raised fasting insulin and HbA1c, a marker of long-term blood sugar control, and showed a trend toward worsening insulin sensitivity.

NewsBiologists uncover a molecular mechanism that helps bacteria spread antibiotic resistance genes
A new study reveals the molecular mechanism behind one of the most powerful mechanical actions in all of biology, the reeling in of tiny surface fibers called type IV pili.

NewsScientists solve decades-old mystery of how malaria parasites invade human cells
Researchers have caught the malaria parasite’s moving junction in the act, obtainingg the first high-resolution view of its three-dimensional structure. It turns out to be a molecular machine that actively remodels the host cell’s membrane to help the parasite force its way inside.

NewsA non-toxic guard against Lyme disease could soon be an everyday purchase
Rather than vaccinating people or pets against Lyme disease, researchers are targeting the “reservoir hosts” — small mammals like squirrels, chipmunks and white-footed mice — that naturally carry the bacterium and pass it to ticks.
-
NewsStudy: Three-in-one vaccine shows promise against ‘tripledemic’
A single-shot vaccine in development could protect against flu, COVID-19 and RSV simultaneously. In a study, researchers found that their three-in-one vaccine triggered protective immunity against all three respiratory diseases in mice, ferrets and cotton rats.

NewsBillions of doses later: Global review confirms mRNA vaccines are safe, effective and full of promise
A comprehensive review brings together global evidence to strengthen public trust and counter misinformation as mRNA vaccines expand to prevent and treat more diseases.
-
NewsTiny DNA ‘hitchhikers’ may be reshaping life in thawing Arctic soils
A new study in the peatlands of northern Sweden provides one of the clearest pictures yet of how frequently microbes swap, gain and lose genes in nature. The study establishes a new framework for measuring genetic mobility in natural environments.

NewsDeep-sea extremophile yields protein that forms super stable biofilm
Scientists have discovered a protein secreted by a deep-sea extremophile — an organism adapted to extreme environmental conditions — that self-assembles into a biofilm and is highly stable, boosting its potential for biomedical applications.
-
NewsBiomarkers may someday help clinicians better detect Borrelia burgdorferi infections
Current tests for Lyme disease often miss infections during the early critical window and cannot tell whether bacteria are still present or were cleared years ago. New research suggests that anti-lipid antibodies may address these shortcomings.
-
NewsTick-borne diseases reported every month of the year and in every Illinois county
A new analysis of state health department data reveals that more than 6,400 Illinois residents were diagnosed with tickborne diseases from 2004-2022.
-
NewsBack in action: Researchers make drug-resistant bacteria vulnerable again
New findings show that disabling a single bacterial protein can restore vancomycin’s power against resistant bacteria – and point to a new strategy for overcoming antibiotic resistance.
-
NewsIntestinal cells found to starve Salmonella of essential nutrients, revealing new tactic in infection defense
A new discovery sheds light on how the human body controls Salmonella infections and opens pathways for potential treatments for Salmonella and other food-borne infections.

NewsResearchers affirm long-held belief that viruses can trigger Parkinson’s disease
Researchers have developed a model that uses a nontoxic way to generate the symptoms of Parkinson’s: infection with a virus. It proves that a simple viral infection can trigger the exact brain damage and physical disabilities in animal models that are seen in people with Parkinson’s disease.
