Using R.N.A. to Kill Cancer
Scientists may have found a molecular bounty hunter—a tiny snippet of R.N.A. called microRNA 31—that can kill wayward cancer cells hiding in parts of the body far from the initial tumor.
If cancer can be stopped once it has spread, lives will be saved. A small section of R.N.A. seems effective at killing breast cancer cells. "A tiny snippet of R.N.A. called microRNA-31 or miR-31 can kill breast cancer cells that have spread to the lungs. The microRNA turns off production of proteins that cells use to build skeletons and cling to each other, researchers at M.I.T. and the Whitehead Institute in Cambridge, Massachusetts, show in a paper published in the March 15 Genes & Development. The microRNA didn’t affect the initial tumor. Therapies that can stop cancer once it has spread may eliminate up to 90 percent of cancer deaths."

A new study explores how certain personality traits affect individuals' attitudes on obesity in others.
- The study compared personality traits and obesity views among more than 3,000 mothers.
- The results showed that the personality traits neuroticism and extraversion are linked to more negative views and behaviors related to obesity.
- People who scored high in conscientiousness are more likely to experience "fat phobia.
The rise of anti-scientific thinking and conspiracy is a concerning trend.
- Fifty years later after one of the greatest achievements of mankind, there's a growing number of moon landing deniers. They are part of a larger trend of anti-scientific thinking.
- Climate change, anti-vaccination and other assorted conspiratorial mindsets are a detriment and show a tangible impediment to fostering real progress or societal change.
- All of these separate anti-scientific beliefs share a troubling root of intellectual dishonesty and ignorance.
The history of the Geneva Conventions tells us how the international community draws the line on brutality.
- Henry Dunant's work led to the Red Cross and conventions on treating prisoners humanely.
- Four Geneva Conventions defined the rules for prisoners of war, torture, naval and medical personnel and more.
- Amendments to the agreements reflect the modern world but have not been ratified by all countries.
