Researchers may have discovered a new method to predict solar flares more than a day before they occur, providing advance warning to help protect satellites, power grids, and astronauts from potentially dangerous radiation. The system works by measuring difference in gamma radiation emitted when atoms in radioactive elements "decay," or lose energy.
Purdue University researchers have created a new imaging technology that reveals subtle changes in breast tissue, representing a potential tool to determine a woman's risk of developing breast cancer and to study ways of preventing the disease. The researchers, using a 3D culture that mimics living mammary glad tissue, also showed that a fatty acid found in some food influences this early precancerous stage.
Researchers have learned how to improve the performance of sensors that use tiny vibrating microcantilevers to detect chemical and biological agents for applications from national security to food processing. This improvement can be seen by measuring amplitude instead of frequency.
The driving bass rhythm of rap music can be harnessed to power a new type of miniature medical sensor designed to be implanted in the body. Acoustic waves from music, particularly rap, were found to effectively recharge the pressure sensor. Such a device might ultimately help to treat people stricken with aneurisms or incontinence due to paralysis.
Purdue University President France A Córdova announced the launch of a new research commercialization center that will move Purdue discoveries to the marketplace more quickly, increase revenue for the university, and spur economic development in Indiana and the nation.
Researchers from the NIST Center for Nanoscale Science and Technology and Purdue University have designed and fabricated an on-chip microresonator that converts continuous laser light into ultra-short pulses consisting of a mix of well-defined frequencies, a technology with applications in advanced sensors, communications systems, and metrology.
Researchers have created new microtweezers capable of manipulating objects to build tiny structures, print coatings to make advanced sensors, and grab and position live stem cell spheres for research.
Purdue University physicists created computational tools that can predict the fleeting structures of iron-containing enzymes as they transform during chemical reactions. Many of these temporary but critical structures have eluded capture through traditional experimental methods such as X-ray crystallography.
Modified probiotics, the beneficial bacteria touted for their role in digestive health, could one day decrease the risk of Listeria infection in people with susceptible immune systems, according to Purdue University research.
Researchers have shown how arrays of tiny "plasmonic nanoantennas" are able to precisely manipulate light in new ways that could make possible a range of optical innovations such as more powerful microscopes, telecommunications, and computers.
Researchers have created a new type of optical device, the passive optical diode, small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.
Engineers have discovered details about the behavior of ultrafast laser pulses that may lead to new applications in manufacturing, diagnostics, and other research.
Scientists at Purdue University and eight other institutions have developed new resources poised to unlock another door in the hidden garden of medicinally important compounds found in plants.
Researchers from Purdue and Harvard universities have created a new type of transistor made from a material that could replace silicon and have a 3D structure instead of conventional flat computer chips.
Purdue University researchers have demonstrated a new imaging technique for tracking carbon nanotubes in living cells and the bloodstream, which could aid efforts to perfect their use in biomedical research and clinical medicine.
A drop in carbon dioxide appears to be the driving force that led to the Antarctic ice sheet's formation, according to a recent study led by scientists at Yale and Purdue universities of molecules from ancient algae found in deep-sea core samples.
People exposed to manganese in occupational settings such as welding may not see signs for years that the element is toxic to their nervous systems, but new medical imaging techniques being developed and tested by a Purdue University professor could help reveal toxicity before symptoms appear that indicate irreversible brain damage.
Researchers are making progress in developing a system that measures the mechanical properties of living cells, a technology that could be used to diagnose human disease and better understand biological processes.
Future astronauts spending Thanksgiving in space may not have to forgo one of the most traditional parts of the day's feast: fresh sweet potatoes. A Purdue University team developed methods for growing sweet potatoes that reduce the required growing space while not decreasing the amount of food that each plant produces.
An asteroid the size of an aircraft carrier will fly near Earth on Nov. 8, 2011. While there is no danger of it hitting the planet, a Purdue University asteroid impact expert says a similar-sized object hitting Earth would result in a 4,000-megaton blast, magnitude 7.0 earthquake and, should it strike in the deep ocean, 70-foot-high tsunami waves 60 miles from the splashdown site.
The merging of two technologies under development—plasmonics and nanophotonics—is promising the emergence of new quantum information systems far more powerful than today's computers. The technology hinges on using single photons for switching and routing in future computers that might harness the exotic principles of quantum mechanics.
Not all parts of a corn stalk are equal, and they shouldn't be treated that way when creating cellulosic ethanol, say Purdue University researchers. When corn stover is processed to make cellulosic ethanol, everything is ground down and blended together. But a research team found that three distinct parts of the stover—the rind, pith, and leaves—break down in different ways.
Purdue University has developed a system to analyze the historic response of U.S. Coast Guard search-and-rescue operations in the Great Lakes and assess the potential risks associated with hypothetical changes in the allocation of resources in the region.
Someday trees could provide more than just shade, scenery, and building materials. Purdue University researchers are studying how poplars might be turned into liquid fuel.
Researchers at Purdue University and NIST have created a device small enough to fit on a computer chip that converts continuous laser light into numerous ultrashort pulses, a technology that might have applications in more advanced sensors, communications systems, and laboratory instruments.
