Over the past few years many of us have become accustomed to unlocking phones and computers with our fingerprints, but a prototype device from a team at Purdue could one day allow payments, passwords and photos to be sent via touch.

Ironclad beetles can survive being run over by a car and scientists have now unlocked some of the secrets behind this incredible toughness, which they say paves the way for a new breed of materials that bear similar characteristics.

Researchers have developed a new white paint that can reflect over 95 percent of sunlight, which can cool the surface even lower than the ambient temperature. Painted on a building, the new paint could help cut cooling costs and energy use.

Scientists at Purdue University have developed a back-flipping microbot that can tumble its way through the colon to release its payload when desired, all while being controlled externally by a magnetic field.

Scientists at Purdue University have developed a mobile docking station that enables underwater robots to stop by for a recharge and offload their data at the same time, offering a way for them to operate for far longer periods without human input.

A typical sheet of paper or cardboard is neither waterproof, interactive or able to harvest energy, but an innovative new printing technology developed at Purdue University can make it all of the above.

For some time now, bacteria-killing ozone gas has been used to help heal chronic wounds such as diabetic skin ulcers. Such treatment could soon be a lot more practical and effective, thanks to an experimental new wearable system.

A new four-year study using AI-enabled surveillance will track recently released prison parolees. The project’s goal is to lower rates of recidivism by identifying early interventions to help individuals transitioning from prison to regular society.

The bacteria that are present in a person's gastrointestinal tract can reveal a lot about their health. A newly developed capsule could provide even more information, by gathering bacteria from specific locations within that tract.

A team of scientists has developed software that could make diagnoses of blood disorders much more straightforward, using a smartphone camera to assess levels of hemoglobin as a way of detecting conditions like anemia.

Perovskite makes for efficient solar cells, but it’s a bit too fragile. Now, a team has found that adding one bulky molecule can stabilize the material, making it stackable in layers and opening up its usefulness in solar cells and other electronics.

Although the causes of chronic indigestion aren't entirely understood, the condition typically involves the stomach not expanding and contracting properly. New research now suggests that in-ear nerve stimulation could help remedy that situation.
