Farmers don't need a new superstar toxin to fight bugs

Researchers found that using plants with moderately effective genetic modifications in a buffer zone around main crops can play a major role in insect control. This approach delays the development of resistant insects by creating negative cross-resistance, effectively eliminating them from invading the main crop.

New biosensor rapidly detects deadly foodborne pathogen

Purdue researchers develop a new optical biosensor that can detect minute quantities of Listeria monocytogenes in less than 24 hours. The sensor is selective enough to recognize only the species monocytogenes and has improved detection capabilities compared to existing commercial test kits.

Virus known for its photo ops makes its movie screen debut

Researchers at Purdue University have created a movie of the T4 virus infection process, revealing conformational changes in the baseplate that enable scientists to visualize the infection process. This improved understanding could lead to deeper insights into viral behavior and potential gene therapy techniques for human patients.

RNA could form building blocks for nanomachines

A research team from Purdue University has successfully created RNA-based nanoscale structures, which could be used as building blocks for microscopic machines. The researchers have developed methods to self-assemble RNA molecules into complex shapes, such as arrays that can form the scaffolding on which other components could be mounted.

Scientists develop plant that produces potential anti-carcinogen

Purdue University researchers have engineered plants to produce a non-toxic form of selenium called methylselenocysteine, which has shown promise in reducing cancer risk in animal models. The plants can also accumulate high levels of selenium, potentially providing a natural source for nutritional supplements and environmental cleanup.

Simple sugars make cell walls like steel

Purdue University scientists discovered that simple sugars, particularly galactose, are essential for maintaining plant cell wall strength. The study found that enzymes break down xyloglucan polymers during growth, allowing microfibrils to separate and new fibers to be integrated, preventing the cell wall from becoming too thick.

Purdue's self-assembled 'nanorings' could boost computer memory

Researchers at Purdue University have created tiny magnetic rings that can store information at room temperature and are self-assembled, promising a new approach to non-volatile computer memory. The nanorings' magnetic states can be switched by applying a magnetic field, paving the way for faster and more affordable computer memories.
