Researchers from the UCLA School of Dentistry have discovered a key molecule that allows cancer stem cells to bypass the body s natural immune defenses, spurring the growth and spread of head and neck squamous cell cancers. Their study, conducted in mice, also demonstrates that inhibiting this molecule derails cancer progression and helps eliminate these stem cells.

Captured carbon dioxide could one day fuel an $800 billion industry
It sounds like science fiction, but for a select few, capturing carbon dioxide (CO2) from energy production emissions to create viable and economical carbon products is a hard-won reality that could breathe new life into the Powder River Basin and other coal communities.
In the five years following the 2015 commencement of the International Carbon X Prize competition, and its conclusion in 2020, where ten teams from five countries strove to identify new economical uses for captured carbon in the hopes of claiming one of two $7.5 million grand prizes, researchers and industry leaders have discovered how to utilize carbon in ways previously unimaginable.

Pamela Hieronymi, a philosophy professor at the University of California, Los Angeles, who researches moral responsibility and free will, pointed to the ethical theory of “contractualism” as a good framework. “We know we all have to find a way to get along, and that we all have to constrain our pursuits in light of other people,” she said. “So contractualism asks: ‘What rules would we all agree to if each person gets a symmetric say?’”
