Cedars-Sinai investigators have detailed a new way that bacteria use iron to cooperate and resist antibiotic treatment. The study, led by the Cedars-Sinai departments of Biomedical Sciences and Pathology and Laboratory Medicine, is published in the peer-reviewed journal Nature Microbiology and is the first to show this type of antibiotic cross-protection.

Combining math and entomology to predict, mitigate soybean aphid outbreaks
Iowa State researchers are developing mathematical models to simulate soybean aphid population dynamics over a growing season with a wide array of stressors, including droughts and floods. The project received a USDA grant earlier this year and is in collaboration with entomologists at Ohio State University.
What is quantum squeezing?
Scientists exploit a property of quantum physics to make ultraprecise sensors and measurements.
Physicists create new model of ringing black holes
When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples called gravitational waves outward in all directions.
Understanding Japan’s earthquakes: New insight into the relationship between slow slip events and the build-up and release of tectonic strain
The Japanese archipelago is actively undergoing seismic shifts due to interactions between the oceanic plate and the continental plate.
COVID calculations lead to unexpected solution to long-standing problem in theoretical computer science
At the beginning of the COVID-19 pandemic, Joachim Kock, mathematician at the Universitat Autònoma de Barcelona (UAB), began to experiment with epidemiological models. He did not improve upon the predictions, but unexpectedly he made a mathematical discovery that led to the solution of an old problem in theoretical computer science, open since the 1980s, on Petri nets.
Adapting language models to track virus variants
Groundbreaking research by Argonne National Laboratory finds new method to quickly identify COVID-19 virus variants. Their work wins the Gordon Bell Special Prize.
New Computational Tools to Help Target Sex, Labor Trafficking Operations
Researchers have developed computational models that can help fight human trafficking. The models draw on publicly available data to identify massage businesses that are most likely to be violating laws related to sex trafficking and labor trafficking.
Researchers Present New Mathematical Model for Studying Kidney Cells
Rockville, Md. (September 13, 2022)—Research published ahead of print in the journal Function presents a new mathematical model using opossum kidney cells to study the endocytic capacity of proximal tubule cells in the kidneys. The specialized cells in the proximal…
The fans are right: When it comes to football, momentum is real
Researchers built a mathematical model that proves the phenomenon of “momentum” in a single NFL game is real rather than random. The model also predicts a game’s outcome based on the research team’s definition of momentum.
Moffitt Researchers Use Mathematical Modeling to Explain Immunotherapy Responses
In a new article published in the Journal for ImmunoTherapy of Cancer, Moffitt Cancer Center researchers demonstrate how mathematical modeling can be used to analyze the impact of different cancer treatments on tumor and immune cell dynamics and help predict outcomes to therapy and personalize cancer treatment.
Never too odd to learn how to swim
KyotoU researchers have now discovered a new formula for swimming based on their study of odd elasticity, or non-reciprocating behavior by microswimmers.
Study: Drug dosage for children could be improved with new method under development
A University at Buffalo-led team of researchers developed a mathematical equation that helps better simulate the impact of drug dosage on children by age, weight and sex.
New Blueprint of Brain Connections Reveals Extensive Reach of Central Regulator
In a new article published in Nature Communications, Moffitt Cancer Center researchers show how the location of the tumor and spatial constraints put on it by the surrounding tissue architecture impact genetic heterogeneity of tumors.
Moffitt Researchers Use Mathematical Modeling to Analyze Dynamics of CAR T-Cell Therapy
In an article published in Proceedings of the Royal Society B, Moffitt Cancer Center researchers use mathematical modeling to help explain why CAR T cells work in some patients and not in others.
COVID-19 Simulation Shows Importance of Continued Safety Efforts During Vaccine Distribution
Research out on the pre-publication website medRxiv shows how non-pharmaceutical interventions (NPIs) like mask wearing and physical distancing can help prevent spikes in COVID-19 cases as populations continue to get vaccinated.
Mathematically Modeling the Return to College Campuses in the Time of COVID-19
A student-built simulation shows why college campuses are particularly prone to rapid spreading of COVID-19 and reinforces the need for quick testing and symptom reporting to find and isolate infected individuals.
Why Does COVID-19 Impact Only Some Organs, Not Others?
In severe cases of COVID-19, damage can spread beyond the lungs and into other organs, such as the heart, liver, kidney and parts of the neurological system. Beyond these specific sets of organs, however, the virus seems to lack impact. Ernesto Estrada aimed to uncover an explanation as to how it is possible for these damages to propagate selectively rather than affecting the entire body. He discusses his findings in the journal Chaos.
Novel insight reveals topological tangle in unexpected corner of the universe
In a recent theoretical study, scientists discovered the presence of the Hopfion topological structure in nano-sized particles of ferroelectrics — materials with promising applications in microelectronics and information technology.
Why Do So Many Pregnancies and In Vitro Fertilization Attempts Fail?
Scientists have created a mathematical model that can help explain why so many pregnancies and in vitro fertilization attempts fail. The Rutgers-led study, which may help to improve fertility, is published in the journal Proceedings of the National Academy of Sciences.
US approaching peak of ‘active’ COVID-19 cases, strain on medical resources, new modeling shows
A new data-driven mathematical model of the coronavirus pandemic predicts that the United States will peak in the number of “active” COVID-19 cases on or around April 20, marking a critical milestone on the demand for medical resources.
Tulane math professor leads effort to map spread of coronavirus
Professor James “Mac” Hyman’s goal is to help the public health community better understand and predict the spread of the COVID-19 and to quantify the effectiveness of various efforts to stop it.
