Ben & Jerry's Uses Sound to Chill Ice Cream

Scientists have developed a new type of refrigeration system for Ben and Jerry's. It chills ice cream using sound waves, rather than with gases that may contribute to climate change. The "thermo-acoustic" chiller is a pricey prototype, but its creators hope the device can be produced for the commercial market. NPR's Robert Smith reports.

Brown v. Board: Disabled Children

Prior to the 1970s, children with disabilities seeking education could not attend public schools and were either sent to private schools or state institutions and lived there under horrible conditions. Lawyers went to court using the Supreme Court's Brown v. the Board of Education decision, and argued that disabled children deserved the same equal education that black children won years earlier. NPR's Joseph Shapiro reports.

One-Parent Mouse Created

Scientists in Japan prove that it is possible to get a live, fertile mouse by activating an egg containing only DNA from female mice. The process of getting an unfertilized egg to start dividing is called parthenogenesis. Although many non-mammalian species reproduce this way, the Japanese mouse is the first known incidence in mammals. NPR's Joe Palca reports.
