NewsPlants that survived dinosaur extinction aided by microbes to pull nitrogen from air
Scientists have found that the cycad species that survived extinction relied on symbiotic bacteria in their roots, which provide them with nitrogen to grow.
-
NewsE coli may be better at evolving resistance than previously thought
E. coli bacteria may be far more capable at evolving antibiotic resistance than scientists previously thought, according to a new study.
-
NewsScientists discover rules for breaking into Pseudomonas
Researchers have found a way to get antibacterial drugs through the nearly impenetrable outer membrane of Pseudomonas aeruginosa, a bacterium that – once it infects a person – is notoriously difficult to treat.
-
NewsWastewater testing improves predictions for COVID-19 hospital admissions
Testing wastewater for COVID-19 provides a better forecast of new COVID hospital admissions than clinical data, a new study suggests.
-
NewsBacteria store memories and pass them on for generations
Scientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms.
-
NewsLaser-powered ‘tweezers’ reveal universal mechanism viruses use to package up DNA
A study using optical tweezers reveals new insights into the roles of specific DNA motor proteins in packaging up viral genomes.
-
NewsResearchers shed light on how one deadly pathogen makes its chemicals
Scientists have deciphered a previously unidentified cluster of genes responsible for producing sartorypyrones, a chemical made by the fungal pathogen Aspergillus fumigatus, whose family causes Aspergillosis in humans.
-
NewsInfection-resistant 3D-printed metals developed for implants
A novel surgical implant is able to kill 87% of the bacteria that cause staph infections in laboratory tests, while remaining strong and compatible with surrounding tissue like current implants.
-
NewsScientists sending microbes to space to see how they grow in low gravity
Researchers will send specimens to the International Space Station to see how biofilms develop in partially and variably water-saturated porous media.
-
NewsStudy reveals bias in AI tools when diagnosing women’s health issue
Machine learning algorithms designed to diagnose a common infection that affects women showed a diagnostic bias among ethnic groups, researchers have found.
-
NewsScientists to eliminate bottlenecks to breakthroughs with a new synthetic biology robotics system
Researchers in UC Santa Barbara’s newly designated Biological Engineering (BioE) Department have received a significant boost from the U.S. Army, which awarded a $9.85 million grant to design and purchase state-of-the-art equipment.

NewsFUN-PROSE predicts the response of fungal genes
Researchers have developed a machine learning approach called FUN-PROSE to predict how genes react to different environmental conditions.
-
NewsPotential therapeutic target found to combat TB, a disrupted NAD(H) homeostasis
A study shows how Mycobacterium tuberculosis perturbs homeostasis of the high-energy molecule NADH and reprograms glycolysis in myeloid cells - highlighting glycolysis as a potential therapeutic target.
-
NewsEvidence of climate change in the North Atlantic can be seen in the deep ocean
Evidence of climate change in the North Atlantic during the last 1,000 years can be seen in the deep ocean, according to a newly published paper.
-
NewsStudy reveals surprising link between malnutrition and rising antibiotic resistance
Researchers have uncovered startling connections between micronutrient deficiencies and the composition of gut microbiomes in early life that could help explain why resistance to antibiotics has been rising across the globe.
-
NewsResearch in Lake Superior reveals how sulfur might have cycled in Earth’s ancient oceans
Researchers have discovered a new type of sulfur cycle in Lake Superior.
-
NewsHeat tolerant coral may trade fast growth for resilience
Rresearchers have found that there is a tradeoff for corals dominated by thermally sensitive algae - they have higher growth, but only in cooler water.
-
NewsStudy proposes new framework to identify keystone microbial species
Researchers have designed a new data-driven keystone species identification (DKI) framework that uses machine learning.
-
NewsCancer therapy shows promise against tuberculosis
A promising new cancer therapy also appears extremely potent against one of the world’s most devastating infectious diseases: tuberculosis (TB).
