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.
Purdue University will lead a new effort aimed at cutting fuel consumption in half for commercial vehicles by perfecting hybrid technologies for the world's burgeoning bus and truck fleets.
Purdue University is part of a national institute that received a grant of up to $35 million over the next five years from the U.S. Food and Drug Administration (FDA). The FDA awarded the grant to the National Institute for Pharmaceutical Technology and Education, or NIPTE, to improve manufacturing standards and ultimately cut health care costs, create jobs, and improve drug safety.
The biofuel industry will not be able to meet the cellulosic production requirements of the Renewable Fuel Standard without significant advancements in technology or investment, according to a National Academy of Sciences study prepared for Congress.
Purdue University researchers will use a portion of a $25 million grant to determine the potential of grasses as environmentally responsible bioenergy crops and to educate farmers and others about the findings.
Anti-caking agents in powdered products may hasten degradation of vitamin C instead of doing what they are supposed to do: protect the nutrient from moisture. A Purdue University team is studying deliquescence, a reaction in which humidity causes a crystalline solid to dissolve, in hopes to understand how anti-caking agents protect substances such as vitamin C from humidity.
A team of Purdue University researchers has invented a prototype water-disinfection system that could help the world's 800 million people who lack safe drinking water. The system uses the sun's ultraviolet radiation to inactivate waterborne pathogens. Sunlight is captured by a parabolic reflector and focused onto a UV-transparent pipe though which water flows continuously.
Purdue University scientists believe they have found an effective target for killing late-stage, metastatic prostate cancer cells. The team is focusing on the function of a gene called Polo-like kinase (Plk1), a critical regulator of the cell cycle. Plk1 is also an oncogene, which tends to mutate and can cause cancer.
Researchers are developing a new type of computer memory that could be faster than the existing commercial memory and use far less power than flash memory devices. The technology combines silicon nanowires with a "ferroelectric" polymer, a material that switches polarity when electric fields are applied, making possible a new type of ferroelectric transistor.
The first fluorescence-guided surgery on an ovarian cancer patient was performed using a cancer cell "homing device" and imaging agent created by a Purdue University researcher. The surgery was one of 10 performed as part of the first phase of a clinical trial to evaluate a new technology to aid surgeons in the removal of malignant tissue from ovarian cancer patients.
A study by researchers from the schools of science and medicine at Indiana University-Purdue University Indianapolis examines the effects of carbon nanoparticles on living cells. This work is among the first to study concentrations of these tiny particles that are low enough to mimic the actual exposure of an ordinary individual.
Purdue University researchers have found an alternative environmentally friendly and energy-efficient way to dry corn ethanol, and their proof is in the pudding. The Purdue team found that the shape and structure of tapioca pearls are ideal for removing water from ethanol.
