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.

A new technology out of Purdue University is a shining example of using green tech to craft next-gen batteries, with scientists using a common form of plastic waste to craft a key component through the use of standard household microwave technology.

Scientists at Purdue University are putting forward another interesting proposition in the realm of home automation, developing a cheap sensor that can detect when a person enters a room via carbon dioxide levels in the air.

We already knew that copper kills bacteria on contact, as it releases ions that rupture bacterial cell membranes. The material could soon do so faster than ever, however, thanks to a new laser-based surface treatment.

The Arctic permafrost is thawing, which could release huge amounts of greenhouse gases stored there. But now researchers have found that methane-munching microbes might counter some of that, resulting in far lower emissions than previously thought.

One consequence of cancer and other diseases spreading throughout the body can be the hardening of the extracellular matrix surrounding cells. Scientists have now developed a new way to non-destructively detect such changes using sound waves.

Many drones already utilize ultrasound to detect obstacles lying directly in their path. A new drone system, however, uses sound to determine where all of the walls are within a room – providing guidance when vision- or light-based systems cannot.

If bacterially-tainted food is present in a store or kitchen, then the sooner that authorities know, the better. That's why scientists have created a device that detects harmful bacteria on the spot, instead of in the lab.

In 2018, researchers created the world’s fastest-spinning object that reached 60 billion rpm – now that seems like the teacup ride at Disneyland. The same team has broken its own record, creating a new nano-scale rotor that spins five times faster.

Scientists at Purdue University have come up with en edible security tag that can be integrated into medicine and emit distinctive light patterns when exposed to LED lights as a way to guarantee its safety and authenticity.
