Disruption of a crucial cellular machine may kill the engine of deadly cancers

Researchers at Baylor College of Medicine have discovered a new way to kill cancers driven by the MYC gene, which is responsible for aggressive behavior in many types of malignancies. By inhibiting the spliceosome, a complex machine within cancer cells, scientists can target and destroy tumor cells without harming normal tissues.

Only above-water microbes play a role in cave development

Research suggests that above-water microbes contribute to the development of hydrogen-sulfide-rich caves through aerobic respiration, producing sulfuric acid. In contrast, underwater microbes only partially burn hydrogen sulfide, creating pure sulfur as a byproduct that is not corrosive to limestone.
