A new genetic tool to modify and understand gene function

Scientists have developed a new genetic tool called iSuRe-Cre that provides certainty in Cre-inducible genetic modifications. This innovation increases the efficiency and reliability of gene function analysis in mice, allowing for precise investigation of gene role during organ development, physiology, and disease.

Detecting bacteria in space

Scientists have pioneered a new genomic methodology to identify and map bacterial species on the International Space Station, aiming to safeguard astronauts' health. The approach has applications in environmental management and healthcare, and will enable researchers to explore new microbiome environments.

Scientists discover the source of new CFC emissions

A new study by an international team of scientists identified a significant increase in CFC-11 emissions in eastern China since 2013, posing a threat to the recovery of the stratospheric ozone layer. The findings suggest that new production of CFC-11 has taken place in the region, primarily for building insulation and refrigerators.

Scientists discover potential breakthrough in the understanding of tumor dormancy

Researchers at VCU Massey Cancer Center have made a significant discovery regarding tumor dormancy, a state of inactivity that allows cancer cells to evade detection and recurrence. By targeting senescent cells, they hope to develop novel therapeutics that can eliminate dormant tumor cells and prevent disease recurrence.

Positive aspects of masculinity helps improve boys' attitudes toward relationship violence

A pilot program focusing on positive expressions of masculinity improved middle school boys' attitudes toward relationship violence, reducing beliefs that coercion and violence are acceptable. The 'Reducing Sexism and Violence Program - Middle School Program' also taught empathy, healthy relationships and bystander intervention skills.

CBD reduces craving and anxiety in people with heroin use disorder

A study published in the American Journal of Psychiatry found that CBD significantly reduced craving and anxiety induced by drug cues in individuals with heroin use disorder. The study also revealed that CBD tended to reduce physiological measures of stress reactivity, such as increased heart rate and cortisol levels.
