Eating an apple a day may keep the doctor away, but eating watermelon may just keep the cardiologist at bay. A study from Purdue University and the University of Kentucky showed that mice fed a diet including watermelon juice had lower weight, cholesterol, and arterial plaque than a control group.
A Purdue University physicist, Leonid Rokhinson, has observed evidence of long-sought Majorana fermions, special particles that could unleash the potential of fault-tolerant quantum computing. Rokhinson led a team that is the first to successfully demonstrate the fractional a.c. Josephson effect, which is a signature of the particles.
Objects created using 3D printing have a common flaw: They are fragile and often fall apart or lose their shape. Researchers at Purdue University and Adobe's Advanced Technology Labs have jointly developed a program that automatically imparts strength to objects before they are printed, spurring on the trend of 3D printing.
Purdue University researchers have created a new type of miniature pump activated by body heat that could be using in drug-delivery patches powered by fermentation. The micropump contains Baker's yeast and sugar in a small chamber, and when water is added and the patch is placed on the skin, the body heat and added water causes the yeast and sugar to ferment, generating a small amount of carbon dioxide gas, which pushes against a membrane and has been shown to pump for several hours.
Purdue University researchers have discovered a swirling, fluid-like behavior in a solid piece of metal sliding over another, providing new insights into the mechanisms of wear and generation of machined surfaces that could help improve the durability of metal parts.
Because of the proliferation of mobile wireless devices, there is not enough radio spectrum to account for everybody's needs. To counter the problem, industry is trying to build systems that operate with more sharply defined channels so that more of them can fit within the available bandwidth. At Purdue University, the recent invention of nanoelectromechanical resonators may provide the solution.
A new nano machine shop that shapes nanowires and ultrathin films could represent a future manufacturing method for tiny structures with potentially revolutionary properties. Purdue University researchers used their technique to stamp nano- and microgears; form tiny circular shapes out of graphene; and change the shape of silver nanowires.
Physicists who study superconductivity strive to create a clean, perfect sample. But a Purdue University team that has mapped seemingly random, four-atom-wide dark lines of electrons on the surface of copper-oxygen based superconducting crystals has discovered that they exist throughout the crystal. The findings suggest the lines, which are “flaws”, could play a role in the material's superconductivity at much higher temperatures than others.
Researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears, and urine, and might be manufactured at low cost because it does not require many processing steps to produce.
Researchers have developed a design tool that enables people to create 3D objects with their bare hands by using a depth-sensing camera and advanced software algorithms to interpret hand movements and gestures.
Researchers have demonstrated tiny machines, called self-calibratable micro-electromechanical systems, or MEMS, that could make possible super-accurate sensors and motors. Although MEMS are in commercial use, the new device is the first of its kind capable of self-calibration, a step critical for applications requiring high performance and accuracy.
Sweet and biomass sorghum would meet the need for next-generation biofuels to be environmentally sustainable, easily adopted by producers, and take advantage of existing agricultural infrastructure, a group of researchers led by Purdue University scientists believes.
Researchers have proposed a method to automatically detect a new class of software glitches in smartphones called "no-sleep energy bugs," which can entirely drain batteries while the phones are not in use.
Professors from Purdue University and the University of North Carolina at Charlotte are bringing editors of academic journals together to reaffirm their commitment to research integrity.
U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail. Because international treaties forbid the detonation of nuclear test weapons, tools that can accurately depict an explosion are becoming critical for national defense.
A new Purdue University-developed process for creating biofuels has shown potential to be cost-effective for production scale, opening the door for moving beyond the laboratory setting.
More than 2 billion years ago, a much fainter sun should have left the Earth as an orbiting ice ball, unfit to develop life as we know it today. Why the Earth avoided the deep freeze is a question that has puzzled scientists, but Purdue University's David Minton believes he might have an answer.
Researchers are edging toward the creation of new optical technologies using "nanostructured metamaterials" capable of ultra-efficient transmission of light, with potential applications including advanced solar cells and quantum computing.
Gasoline prices this summer could stay relatively steady provided that an already-tense Middle East doesn't flare up and nothing else happens to disrupt supplies, a Purdue University economist says.
Researchers have shown how to create morphing robotic mechanisms and shape-shifting sculptures from a single sheet of paper in a method reminiscent of origami, the Japanese art of paper folding. The new method, called Kaleidogami, uses computational algorithms and tools to create precisely folded structures.
Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and "personalized medicine" tailored to the specific biochemistry of individual patients. The device, which could be several hundred times more sensitive than other biosensors, combines the attributes of two distinctly different types of sensors.
Researchers have taken a step toward overcoming a key obstacle in commercializing "hyperbolic metamaterials," structures that could bring optical advances including ultrapowerful microscopes, computers, and solar cells. The researchers have shown how to create the metamaterials without the traditional silver or gold previously required.
A team of Purdue University researchers will use a $1.6 million federal grant to advance sensor technology and computer simulation tools for tracking and improving the performance and reliability of "smart" wind turbines and wind farms.
Researchers have created a next-generation zoom function to view and compare portions of complex graphics such as city maps, scientific images, or pages of text. The new tool, PolyZoom, makes it possible to simultaneously magnify many parts of a graphic without losing sight of the original picture.
In a study from Stanford University and Purdue University, researchers have shown for the first time that climate change may force the U.S. corn belt to move north in the next 10 years, escaping devastating heat waves. In turn, this will bring substantial price swings to the corn market, adversely affecting industries like food and biofuels.
