Phase III POSEIDON trial shows positive results for patients taking chemotherapy plus durvalumab and tremelimumab

The Phase III POSEIDON trial demonstrated a statistically significant improvement in progression-free survival and overall survival for patients with metastatic non-small cell lung cancer (mNSCLC) treated with chemotherapy plus durvalumab and tremelimumab. Durvalumab combined with tremelimumab and chemotherapy reduced the risk of death...

Math researchers find new ways to improve the science of ‘trade-offs’

QUT researchers developed a new mathematical model to enable faster solutions for complicated problems in agriculture, ecology and medicine. The method improves how to determine the 'best' intervention strategies, balancing benefits and side effects, and can be applied to farming practices and chemotherapy.

Low-poverty US communities may eliminate cervical cancer by 2030 but high-poverty communities may lag behind

A predictive model estimated that cervical cancer may be eliminated in the US by 2030 in low-poverty areas, but not until 2044 in high-poverty areas. Health care disparities are a major contributor to these disparities, including lower vaccination rates and higher prevalence of cancer-causing HPV types.

Disparities in opioid overdose deaths continue to worsen for Black people, study suggests

A recent NIH-supported study highlights alarming disparities in opioid overdose deaths among non-Hispanic Black individuals in the US. The rates increased by 38% from 2018 to 2019, with Kentucky and Ohio experiencing the largest increases. The research emphasizes the need for community-based interventions addressing these disparities.

Lasting immunity and protection from new single-shot, room-temperature stable COVID-19 vaccine

A novel gene-based COVID-19 vaccine leveraging an adeno-associated viral vector platform was highly effective in eliciting neutralizing antibody responses and cellular immunity from a single dose. The vaccine provided near-complete protection against SARS-CoV-2 challenge in nonhuman primates for at least 11 months.

Houser to receive funding for doctoral dissertation research in economics: Asymmetric Shocks In Contests: Theory and Experiment

Daniel E. Houser and Jian Song will investigate how the distribution of random shocks affects effort provisions in rank-tournament participants using economic theory and laboratory experiments. The research aims to develop an improved understanding of why and how people make decisions when facing unlikely but possible bad outcomes.

500-million-year-old fossil represents rare discovery of ancient animal in North America

Researchers uncover a 500-million-year-old 'worm-like' fossil, expanding the number of worm-like species known from this time period in North America. The discovery provides new clues about prehistoric environments and ecologies, helping scientists better understand the diversity of ancient animals during the Cambrian explosion.

Mapping the evolution of materials

Lehigh University researchers are developing a model to understand the impact of grain growth on material properties. The project aims to create new materials informatics methods, innovative stochastic differential equations, and models of grain growth to improve material performance and reliability.

A T-cell power-up for tumor treatments

Researchers at USC Viterbi School of Engineering have discovered a way to boost the effectiveness of CAR T-cell therapy for treating solid tumors, including breast and melanoma. By engineering CAR T-cells to produce an enzyme called adenosine deaminase, they break down an immune-suppressive microenvironment, allowing cancer-killing cel...

New study on COVID-19 vaccinations in the largest US cities finds stark inequities

A new study by Columbia University Mailman School of Public Health reveals stark racial, ethnic, and socioeconomic inequities in COVID-19 vaccination rates across neighborhoods in the largest US cities. High-vaccination neighborhoods were predominantly white with fewer people of color, higher incomes, and lower poverty rates.

Natural killer cells coordinate wound healing

Researchers discovered that natural killer cells play a crucial role in wound healing by accelerating blood vessel growth. However, this process increases the risk of bacterial infections. The study suggests harnessing killer cells to fight antibiotic-resistant bacteria and finding a balance between wound healing and immune defense.

Forest fires linked to tens of thousands of avoidable deaths

A new study quantifies the contribution of agricultural and forest fires to poor air quality in Southeast Asia, finding that preventing these fires could reduce premature deaths by an estimated 59,000 annually. The region's poorest communities are disproportionately exposed to air pollution from these fires.
