Mathematicians based in Australia and China have developed a method to analyze the large amount of data accumulated during the COVID-19 pandemic. The technique, described in the journal Chaos, can identify anomalous countries -- those that are more successful than expected at responding to the pandemic and those that are particularly unsuccessful. The investigators analyzed the data with a variation of a statistical technique known as a cluster analysis.

UC Davis MIND Institute researchers found an unexpected spectrum of mental illnesses in patients with a rare gene mutation. These patients had a “double hit” condition that combined features and symptoms of fragile X syndrome and premutation disorder, in addition to a range of psychiatric symptoms. The findings revealed the need for clinicians to consider the complexities of the co-existing conditions of patients with both psychological and fragile X associated disorders.

While some STEM majors have a one-to-one male-to-female ratio, physics, engineering and computer science (PECS) majors consistently have some of the largest gender imbalances among U.S. college majors – with about four men to every woman in the major. In a new study published today in the peer-reviewed research journal, Science, NYU researchers find that this disparity is not caused by higher math or science achievement among men. On the contrary, the scholars found that men with very low high-school GPAs in math and science and very low SAT math scores were choosing these math-intensive majors just as often as women with much higher math and science achievement.

How can epidemics spread so quickly among entire populations? The Newsroom asked an expert, Cedars-Sinai research scientist Dalin Li, PhD, to explain the math behind the spread of COVID-19. Li was the first author of a recent study that showed how just a few infected individuals who came to the U.S could have generated more than 9,000 COVID-19 (coronavirus) cases.

One of the many questions researchers have about the COVID-19 virus is how long it remains alive after someone infected coughs or sneezes. In Physics of Fluids, researchers examine the drying time of respiratory droplets from COVID-19-infected subjects on various surfaces in six cities around the world. Using a model well established in the field of interface science, the drying time calculations showed ambient temperature, type of surface and relative humidity play critical roles.

A Rutgers engineer has created a mathematical model that accurately estimates the death toll linked to the COVID-19 pandemic in the United States and could be used around the world. The model, detailed in a study published in the journal Mathematics, predicted the death toll would eventually reach about 68,120 in the United States as a result of the SARS-CoV-2 coronavirus that causes COVID-19. That’s based on data available on April 28, and there was high confidence (99 percent) the expected death toll would be between 66,055 and 70,304.
