A compound and an enzyme that occur naturally in cruciferous vegetables—cauliflower, cabbage, broccoli and Brussels sprouts—may help prevent recurrence and spread of some cancers, according to associate professor Moul Dey of the South Dakota State University Department of Health and Nutritional Sciences. When Dey and her team treated human cervical cancer stem cells with phenethyl isothiocyanate (PEITC) in a Petri dish, about 75 percent died within 24 hours using a 20-micromolar concentration of the compound.

In a synergy between the Hubble and Spitzer space telescopes, and the giant W. M. Keck Observatory, astronomers have set a new distance record to the farthest redshift-confirmed galaxy. It is so far away the light we receive left the galaxy over 13 billion years ago, and it is just arriving now. The new observations underline the very exciting discoveries that NASA's James Webb Space Telescope will enable when it is launched in 2018.
