Urban trees rooted in redlining and environmental injustice

A University of Maryland-led study finds that street trees in Baltimore reflect the city's history of institutionalized racism but also modern reparation efforts. Researchers discovered that green neighborhoods have more diverse tree communities and larger, older trees, while redlined areas have less diverse tree species.

Survival is a mixed matter for deadliest of pancreatic cancers

Researchers found that the quality and mix of collagen in pancreatic ductal adenocarcinoma tumors affects prognosis. Patients with tumors containing cleaved Collagen I experienced poor survival prospects, while those with non-cleaved Collagen I had better outcomes.

The determinants of persistent and severe COVID-19 revealed

The study found that imbalances in the host immune system facilitate persistent or severe forms of COVID-19. Low levels of dendritic cells, which report information about invaders to T cells, were associated with long-term infection and disease severity.

The costs of caring for a graying population

Researchers found significant regional differences in LTC spending, driven by factors such as population demographics and disability classification. Preventive measures may help reduce costs by reducing the need for long-term care.

Climate simulation more realistic with artificial intelligence

Researchers used machine learning algorithms to optimize climate models, increasing their accuracy and detail. By applying Generative Adversarial Networks (GANs) to climate simulations, the team was able to improve the models' ability to represent extreme precipitation events.
