Researchers add new tool to tumor-treatment arsenal

A new study demonstrates the potential effectiveness of treating tumors by combining agents that damage DNA with a drug that sensitizes cancer cells to these agents. The research, led by George Thomas, PhD, professor at the University of Cincinnati's (UC) Genom...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

A new study investigating the respiratory system of insects may have solved a mystery that has intrigued physiologists for decades: why insects routinely stop breathing for minutes at a time. Challenging previous theories, researchers at UC Irvine and Humboldt ...
