University of Cincinnati Cancer Center study identifies potential new target to overcome breast cancer resistance

A University of Cincinnati Cancer Center study identifies microRNA miR-205 as a promising new target to overcome breast cancer treatment resistance and improve outcomes. The research found that boosting levels of miR-205 could block the production of MED1, a protein responsible for treatment resistance, and improve treatment outcomes.

Earth’s air war: Explaining the delayed rise of plants, animals on land

A Yale-led study suggests that elevated marine iodine concentrations prevented a protective ozone shield from forming in the Earth's atmosphere, delaying the emergence of complex life on land. This delay led to unstable and low ozone levels persisting for hundreds of millions of years, exposing the planet to high fluxes of solar UVR.

Researchers have a better understanding of how our cells dispose of waste while developing ways to control it

Scientists have identified the crucial role of weak molecular interactions in triggering autophagy, a process that breaks down unnecessary cell components. By artificially controlling these interactions, researchers aim to improve the degradation of aggregates in neurodegenerative diseases and enhance cancer treatments.

Desert nectar: Agave genome study sheds light on drought tolerance

Researchers have uncovered key genes and regulatory pathways governing crassulacean acid metabolism (CAM) photosynthesis in Agave hybrid NO.11648, a process critical for plant survival in arid climates. The study provides a comprehensive analysis of the genome, revealing a whole-genome duplication event and identifying transcription fa...

For many low-income single moms, government aid serves as their paid family leave, study shows

A new study from Oregon State University reveals that many low-income single mothers rely on government cash assistance around childbirth as a form of paid family leave. The study found that most participants use the program for less than a year, highlighting its potential to support vulnerable families during critical life transitions.

University of Minnesota scientists advance nanobody technology to combat deadly Ebola virus

Researchers at the University of Minnesota have developed two new nanobody inhibitors for Ebola: Nanosota-EB1 and Nanosota-EB2. These tiny antibodies target different parts of the virus, preventing it from attaching to cells and spreading. Lab tests show promising results, achieving a 100% survival rate in Ebola-infected mice.

Guildford’s first “living school gate” and green infrastructure deliver major health and environmental benefits

A pioneering study at Guildford's Sandfield Primary School demonstrates the benefits of protective green infrastructure in reducing particle pollution levels and traffic-related noise. The 'living school gate' installation showed a nearly one-third reduction in air pollution, as well as a 5-decibel decrease in distracting traffic noise.
