Purdue team creates ‘engineered organ’ model for breast cancer research

WEST LAFAYETTE, Ind. - Purdue University researchers have reproduced portions of the female breast in a tiny slide-sized model dubbed "breast on-a-chip" that will be used to test nanomedical approaches for the detection and treatment of breast ...

Gene helps plants use less water without biomass loss

WEST LAFAYETTE, Ind. - Purdue University researchers have found a genetic mutation that allows a plant to better endure drought without losing biomass, a discovery that could reduce the amount of water required for growing plants and help plants s...

Turfgrass fertility, pesticide programs compared

WEST LAFAYETTE, IN -- Traditional turfgrass management programs rely heavily on the use of synthetic pesticides and fertilizers. In response to increased public scrutiny and legislation, organic and biological alternatives are becoming more acc...

Bulb dipping controls Easter lily growth

WEST LAFAYETTE, IN -- In a recent issue of HortTechnology, Purdue University researchers Christopher J. Currey and Roberto G. Lopez reported on a study of the effects of a technique called "bulb dipping" on Easter lily. While plant growth retardant...

Eat safer: Novel approach detects unknown food pathogens

INDIANAPOLIS -- Technologies for rapid detection of bacterial pathogens are crucial to maintaining a secure food supply. Researchers from the School of Science at Indiana University-Purdue University Indianapolis (IUPUI) and the Bindley Bi...

New pump created for microneedle drug-delivery patch

WEST LAFAYETTE, Ind. - Purdue University researchers have developed a new type of pump for drug-delivery patches that might use arrays of "microneedles" to deliver a wider range of medications than now possible with conventional patches. The c...

Tiny bubbles are key to liquid-cooled system for future computers

Researchers have made a discovery that may lead to the development of an innovative liquid-cooling system for future computer chips, which are expected to generate four times more heat than today's chips. Researchers had thought that bubbles might block the circulation of liquid forced to flow through "microchannels" only three times the width of a human hair. Engineers also thought that small electric pumps might be needed to push liquid through the narrow channels, increasing the cost and complexity while decreasing the reliability of new cooling systems for computers. Purdue researchers, however, have solved both of these potential engineering hurdles, developing a "pumpless" liquid-cooling system that removes nearly six times more heat than existing miniature pumpless liquid-cooling systems, said Issam Mudawar, a professor of mechanical engineering.

Researchers close in on natural solution to PCB contamination

An environmentally friendly solution to one of the world's most notorious chemical contamination problems may be a step closer to reality, reports a research team from Purdue University and the University of British Columbia. The team has identified one of the key stumbling blocks that prevent microorganisms from decomposing PCBs (polychlorinated biphenyls), a persistent and potentially hazardous industrial chemical that has become nearly ubiquitous in the environment. While capitalizing on the discovery will take time, it could eventually show researchers how to teach microorganisms to break down PCBs into ecologically safe molecules, a process known as bioremediation.
