Phys.org / Molecular switch that activates cell growth signaling may offer more precise route for anticancer therapy

Cells carry their own growth switches. When enough nutrients—amino acids in particular—are available, cells flip this switch on and begin to grow. Researchers at KAIST and Yonsei University have uncovered the molecular mechanism ...

Phys.org / Research cautions that sometimes working together can actually spur inequality

Encouraging people to contribute to a common good can have a surprising drawback: a risk that rewards become concentrated among a smaller group, putting the rest at a disadvantage. Put more simply, "equality and cooperation ...
