Intestinal bacteria influence the growth of fungi

Researchers discovered that certain bacterial species, including lactic acid bacteria, correlate with high levels of Candida yeasts in the gut microbiome. This suggests a complex interaction between these microorganisms, where lactic acid bacteria may favor Candida proliferation while making the fungus less virulent.

Like ancient mariners, ancestors of Prochlorococcus microbes rode out to sea on exoskeleton particles

A new study proposes that ancestors of Prochlorococcus microbes used chitin particles as rafts to venture into the open ocean. This enabled them to evolve new abilities and eventually thrive in the nutrient-poor waters, playing a crucial role in absorbing CO2 from the atmosphere.

Cervical cancer screening doubles when under-screened women are mailed testing kits

Researchers found mailing HPV self-collection tests and offering assistance improved cervical cancer screening nearly two-fold among low-income women. Screening uptake increased to 72% among women who received mailed HPV kits, compared to 37% for those with scheduling assistance alone.

USC research identifies biomarker that may predict treatment response to chemoimmunotherapy

Researchers at USC Norris Comprehensive Cancer Center have identified a biomarker, CX3CR1, that can predict which patients with non-small cell lung cancer will respond well to chemoimmunotherapy. Elevated levels of the biomarker in T-cells after six to nine weeks of treatment indicate long-term benefits from the combination therapy.

These sounds are out of this world! #ASA184

A software program designed by Timothy G. Leighton predicts the environmental sounds of other planets and how human voices might change in distant worlds. The program uses acoustics and planetary science communities to learn about properties such as chemical composition, atmospheric temperature changes, and roughness of the ground.

Celestial monsters at the origin of globular clusters

A team of astronomers has discovered chemical traces of supermassive stars in globular proto-clusters, born 440 million years after the Big Bang. The study suggests that these 'celestial monsters' enriched the original gas cloud with chemical elements, explaining abundance anomalies in their stars.
