Inspired by the eyes of mantis shrimp, researchers have developed a new kind of optical sensor that is small enough to fit on a smartphone but is capable...

Date Time Cloudy eyes caused by protein imbalance Cataracts are the most common eye ailment in humans. However, the exact processes leading to this condition are not fully understood. A team of researchers headed by the Technical University of Munich (TUM) has now discovered that the composition of the protein solution plays a decisive role. Their conclusions are contrary to prevailing opinion in the field. The cells in the lens consist of a highly concentrated protein solution that is normally clear. “When the balance of the proteins in the lens is destroyed, they clump together and the l...

Date Time Poor brain cancer survival outcomes on rise A first of its kind Australian study has revealed rates of brain lymphoma have quadrupled since the 1980s with only 33% of people surviving 5 years after receiving a diagnosis. Brain lymphoma is a Non-Hodgkin lymphoma in which cancer cells from lymph tissue form in the brain or spinal cord. As the human eye is connected to the brain, the lymphoma can also start in the eye (retinal lymphoma) and later spread to the brain. First author of the study published in the journal Cancers, Dr Alexandra Farrall at Flinders University, says the result...

Scientists Create New Contact Lens Sensor Recently, scientists have developed a new contact lens sensor that differs significantly from other previous designs. What does this sensor allow for, what challenges do electronics face in such applications, and how can it help the medical field? How the Human Eye is Challenging As discussed several times in other articles, the human body is wet, gooey, and unbelievably complex with an extremely unforgiving environment. To put into perspective how difficult an environment the human body is, it’s objectively easier to design a circuit to operate in ...

New Perovskite Sensor Mimics the Human Eye Image Credit: CG Alex / Shutterstock.com A newly developed retinomorphic sensor that operates like the mammalian eye could help change the way computer processors operate.  One thing has always eluded programmers and engineers; the ability to build a computer that 'thinks' like a human brain. A new type of sensor that processes information like the human eye could hold the key to this computing breakthrough, speeding up information processing and cutting down energy demands. The 'retinomorphic' device developed by a team of researchers from Oregon U...
