A teenage girl has created a 3D-printed lens and app that can detect eye disease

A teenage girl has created a 3D-printed lens that, when fitted onto a smartphone and used with an app, can give a preliminary diagnosis for people with diabetic retinopathy, reportsIEEE Spectrum. Diabetic retinopathy is the most common cause of vision loss for those who suffer from diabetes, and diagnosis of the disease is usually done via a two-hour exam, which also requires a specialized camera to take a photo of the retina. Sixteen-year-old Kavya Kopparapu, along with her team, trained an AI system to identify diabetic retinopathy in photos instead, sharply cutting down the time it takes for a diagnosis.


The system can spot diabetic retinopathy with the same accuracy of a human doctor. In October, Kopparapu partnered with Aditya Jyot Eye Hospital in Mumbai, India, to test her app Eyeagnosis. By that time, the app could not only detect diabetic retinopathy in images, but also blood vessels and other details that would usually require a fluorescent dye injection. Kopparapu has since shipped the first prototype of her smartphone lens to the hospital, which works by focusing the smartphone’s flash to illuminate the retina

The History Behind The 2 Minute Maggi Noodles!!

The History of Julius Maggi MAGGI owes its name to founder Julius Maggi (1846 - 1912), entrepreneur and inventor of the first product to bear the brand - MAGGI Soup Seasoning. Born in Frauenfeld, Switzerland, Julius took over a hammer mill from his father in 1869. At the time the milling industry was in crisis so Julius decided to open up new areas of production. He got in touch with physician Fridolin Schuler who had a concept for improving the nutritional content of meals for the labouring classes by making packaged foods out of milled pulses or legumes. Together they began product development and after two years of experimentation, the first industrially produced leguminous flour was put on the Swiss market in 1884. When the expected market breakthrough failed to occur, Julius went back to the drawing board and created MAGGI ready-to-use soups in in 1886, then launched MAGGI flavouring later in the year. More and more new products followed between 1887 and 1889. Julius op

This is NASA's plan if an asteroid is heading to Earth.

The following are   NASA's plan if an asteroid is heading to Earth  Step 1: A text message would be sent to a team of 12 scientists.  Step 2: The scientist immediately start tracing the asteroid's path  Step 3:  They measure the size of the object and predict the time of impact  Step 4: They confirm with authorities whether the impact is unavoidable.  Step 5: A public statement would then be issued. Photo by  Bryan Goff  on  Unsplash Then NASA and emergency agencies how best to protect the Earth. They have simulated this experiment many times and come up with a few defensive options. They include firing lasers into the asteroid. Crashing a spacecraft into an approaching asteroid is another possibility. As is detonating a bomb next to an incoming object. There is no risk at the moment though. NASA can't detect any asteroid currently heading towards us. No large object is likely to strike for at least several hundred years.
