Tool Enables Accurate Detection of Microbes in Cancer Genomes

When scientists sequence tumor DNA, they typically find small amounts of genetic code from bacteria, viruses and fungi – microorganisms that, if actually present in tumor tissues, could influence how they grow, evade immunity or respond to treatment.

Scientists Discover Genetic Switch that Controls Candida's Toxin Production

The yeast fungus Candida albicans employs the toxin candidalysin not only to cause infections but also to inconspicuously colonize the oral mucosa—though only in precisely regulated amounts.

Discovery Reveals Spinal Neurons as Active Players in Sexual Behavior

For decades, it was thought that while the brain orchestrated male sexual behavior – arousal, courtship, and copulation – the spinal cord merely executed the final act: ejaculation. But a study from the Champalimaud Foundation (CF) challenges that tidy division.

Molecular Blueprint Reveals Structure and Delivery of Botulinum Toxin

Researchers at Stockholm University have succeeded in creating a molecular blueprint of how one of the world's most dangerous toxins, botulinum toxin, is structured, stabilized, delivered and released.

Living Bacterial Sensors Translate Environmental Signals into Electrical Data

Researchers at Rice University have engineered E. coli to act as living multiplexed sensors, allowing these genetically modified cells to detect and respond to multiple environmental toxins simultaneously by converting their biological responses into readable electrical signals.
