WEST LAFAYETTE, Ind. - Researchers have taken a step toward practical applications for "hyperbolic metamaterials," ultra-thin crystalline films that could bring optical advances including powerful microscopes, quantum computers and high-performance solar cells. New developments are reminiscent of advances that ushered in silicon chip technology, said Alexandra Boltasseva, a Purdue University associate professor of electrical and computer engineering.
DNA Samples from Purdue, Kew Fungi Collections Provide Key to Mushroom 'Tree of Life'
WEST LAFAYETTE, Ind. - Genetic material from fungi collections at Purdue University and the Royal Botanic Gardens, Kew, helped a team of researchers resolve the mushroom "tree of life," a map of the relationships between key mushroom species and their evolutionary history that scientists have struggled to piece together for more than 200 years.
Nicotinoid And Fungal Disease Team Up to Break Down Termites' Tough Defenses
WEST LAFAYETTE, Ind. - Purdue University research shows that a small amount of nicotinoid pesticide substantially weakens termites' ability to fight off fungal diseases, a finding that could lead to more effective methods of pest control. The study also provides clues into termites' robust defense systems and how nicotinoids affect social insects.
Findings Reveal Clues to Functioning of Mysterious 'Mimivirus'
WEST LAFAYETTE, Ind. -- Researchers have discovered the structure of a key protein on the surface of an unusually large virus called the mimivirus, aiding efforts to determine its hosts and unknown functions. The mimivirus was initially thought to be a bacterium because it is much larger than most viruses. It was isolated by French scientists in 1992 but wasn't confirmed to be a virus until 2003.
Evolution in Action: Mate Competition Weeds Out GM Fish from Population
WEST LAFAYETTE, Ind. - Purdue University research found that wild-type zebrafish consistently beat out genetically modified Glofish in competition for female mates, an advantage that led to the disappearance of the transgene from the fish population over time.
Study Illuminates Role of Cancer Drug Decitabine in Repairing Damaged Cells
WEST LAFAYETTE, Ind. - A Purdue University study sheds light on how cell damage is reversed by the cancer drug decitabine and identifies a potential biomarker that could indicate a patient's stage of cancer and response to treatment.
Inkjet-printed Liquid Metal Could Bring Wearable Tech, Soft Robotics
WEST LAFAYETTE, Ind. -- New research shows how inkjet-printing technology can be used to mass-produce electronic circuits made of liquid-metal alloys for "soft robots" and flexible electronics.
New Instrument Dates Old Skeleton; 'Little Foot' 3.67 Million Years Old
WEST LAFAYETTE, Ind. -- A skeleton named Little Foot is among the oldest hominid skeletons ever dated at 3.67 million years old, according to an advanced dating method.
New Class of Insecticides Offers Safer, More Targeted Mosquito Control
WEST LAFAYETTE, Ind. - Purdue researchers have identified a new class of chemical insecticides that could provide a safer, more selective means of controlling mosquitoes that transmit key infectious diseases such as dengue, yellow fever and elephantiasis.
