Mathematical model predicts COVID-19 hospitalizations for those with underlying conditions

Mathematical model predicts COVID-19 hospitalizations for those with underlying conditions

Mathematician Steven G. Krantz in Arts & Sciences at Washington University in St. Louis is using a mathematical tool called wavelets to combat underreporting in the COVID-19 pandemic. His latest model predicts the number of near-term hospitalizations for older adults with one or a combination of underlying conditions: hypertension, cardiovascular disease and lung disease.
Lizards develop new ‘love language’

Lizards develop new ‘love language’

Free from the risk of predators and intent to attract potential mates, male lizards relocated to experimental islets in Greece produce a novel chemical calling card, according to new research from biologists in Arts & Sciences at Washington University in St. Louis.
Fossil discoveries rewrite our family history

Fossil discoveries rewrite our family history

An international team of researchers that includes anthropologists at Washington University in St. Louis has unearthed the earliest known skull of Homo erectus, the first of our ancestors to be nearly human-like in their anatomy and aspects of their behavior. The effort was led by La Trobe University in Australia.
Weedy rice is unintended legacy of Green Revolution

Weedy rice is unintended legacy of Green Revolution

Weedy rice is a feral form of rice that infests paddies worldwide and aggressively outcompetes cultivated varieties. A new study led by biologists at Washington University in St. Louis shows that weed populations have evolved multiple times from cultivated rice, and a strikingly high proportion of contemporary Asian weed strains can be traced to a few Green Revolution cultivars that were widely grown in the late 20th century.
Long-term analysis shows GM cotton no match for insects in India

Long-term analysis shows GM cotton no match for insects in India

Genetically modified Bt cotton is the most widely planted cotton crop in India by acreage, and it is hugely controversial. Supporters long touted increased yields and reduced pesticides to justify its pickup. But that argument does not hold up under the first long-term study of Bt cotton impacts in India. The analysis is co-authored by a Washington University in St. Louis anthropologist in the journal Nature Plants. 
Hot time in the city: Urban lizards evolve heat tolerance

Hot time in the city: Urban lizards evolve heat tolerance

Faced with a gritty landscape of metal fences, concrete walls and asphalt pavement, lizards that moved into cities in Puerto Rico rapidly and repeatedly evolved better tolerance for heat than their forest counterparts, according to new research from Washington University in St. Louis and the University of California, Los Angeles.
