Google making sugar-sensing contact lens for diabetics

SAN FRANCISCO: The Google lab known for working on unusual projects like self-driving cars is crafting a contact lens that could help diabetics manage blood sugar levels.
"We're now testing a smart contact lens that's built to measure glucose levels in tears," project co-founders Brian Otis and Babak Parviz said in a blog post.
The lens works "using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material," Otis and Parviz said.
They said prototypes have undergone clinical tests and talks were underway with the US Food and Drug Administration. The project was described as being in its early days, and partners were being sought to make the lenses marketplace reality.
"As you can imagine, tears are hard to collect and study," the Google X lab team members said.
"We wondered if miniaturized electronics — think chips and sensors so small they look like bits of glitter, and an antenna thinner than a human hair — might be the way to crack the mystery of tear glucose and measure it with greater accuracy."
Prototype lenses being tested at Google X can generate glucose readings about once a second. Researchers are looking into integrating tiny lights that would warn when blood sugar levels go above or below threshold levels, according to the blog post.
"We've always said that we'd seek out projects that seem a bit speculative or strange," Otis and Parviz said.
"At a time when the International Diabetes Federation is declaring that the world is 'losing the battle' against diabetes, we thought this project was worth a shot."
Google cited figures indicating that diabetes affects one in every 19 people on the planet.

Where We Are Going Today: Knead

  • Knead isn’t just a cafe — it is also an authentic bakery

Knead is a great option for anyone looking for something new within this growing trend of cafes. Knead isn’t just a cafe — it is also an authentic bakery that offers a wide range of goods to enjoy with an excellent cup of coffee.

Knead is a cozy place that guarantees a fun time with friends, family or even for work. The food is fresh and delicious.

I liked their donuts more than anything. They are freshly baked and have that perfect texture where you feel like you have bitten into a cloud. The flavors are also brilliant; my favorite was the raspberry donut but other flavors such as butterscotch are also popular.

The staff are friendly and accommodating. They are close to each other, which adds extra warmth to the experience because when you visit it feels like stepping into a family gathering.
