Researchers say they've developed the first insulin that doesn't need to be refrigerated

Scientists in India have made a major medical breakthrough by producing the first "thermostable" variety of insulin that doesn't need to be refrigerated. The research was led by two scientists from the Bose Institute and the Indian Institute of Chemical Biology (IICB) and two others from the Indian Institute of Chemical Technology (IICT).

This development is fantastic news for diabetics because it will make it a lot easier for them to store this life-saving medication. The product labels from all three of America's insulin manufacturers state that insulin should be stored in a refrigerator at approximately 36°F to 46°F.


If the insulin gets too warm or too cold for an extended period of time, it begins to break down and become ineffective. When insulin has broken down, it doesn't show any signs of being ruined. But when it's injected by the user it can be ineffective at managing their blood sugar levels. This can lead to serious health problems.

This means that insulin users have to take extra caution when traveling, so they're sure their medication stays at the correct temperature. It can also be a major problem during natural disasters when refrigerators go out and insulin users can't keep the temperature of their medicine low enough.

The researchers claim this new version of insulin will be able to withstand temperatures up to 149 °F.

They created a thermostable version of the drug by introducing a matrix of four amino acid peptide molecules. These molecules prevent the solidification of the insulin molecules when not refrigerated.

"You will be able to keep it outside the refrigerator for as long as you want, something that will help diabetes patients across the world because carrying insulin along with them was considered impossible all this while," said Subhrangsu Chatterjee, a faculty member at Bose Institute.

"Though for the moment we are calling it 'insulock', we are in the process of appealing to the department of science and technology (DST) to name it after Acharya Jagadish Chandra Bose," he added.

The scientists hope that their research will lure investors to help them mass-produce the new medication.

There's no telling when or if the new drug will be approved for safe use by the FDA and made available in America. But there's a compelling reason to bring it stateside. The researchers say that it will make the drug more affordable. In the U.S. that's big news because the price of insulin has been steadily increasing for the past 15 years.

A report in Health found that the price of Eli Lilly's Humalog insulin has increased 1,200% since it was first produced. In 1996, a one-month supply cost $21; by 2019 it had risen to $275. The ever-rising price of insulin in the United States is unprecedented given its cost throughout the rest of the developed world.

According to a 2020 study by RAND Health Care, the average gross manufacturer price for a standard unit of insulin in the United States in 2018 was more than 10 times the price of a unit in 32 foreign countries.

Craig Ferguson was the host of "The Late Late Show" on CBS from 2005 to 2014. He's probably best remembered for his stream-of-conscious, mostly improvised monologues that often veered from funny observations to more serious territory.

In 2009, he opened his show explaining how marketers have spent six decades persuading the public into believing that youth should be deified. To Ferguson, it's the big reason "Why everything sucks."

"The Carol Burnett Show" had one of the funniest outtakes in TV history.

"The Carol Burnett Show" ran from 1967 to 1978 and has been touted as one of the best television series of all time. The cast and guest stars of the show included comedic greats such as Tim Conway, Betty White, Steve Martin, Vicki Lawrence, Dick Van Dyke, Lyle Waggoner, Harvey Korman and others who went on to have long, successful comedy careers.

One firm rule Carol Burnett had on her show was that the actors stay in character. She felt it was especially important not to break character during the "Family" scenes, in which the characters Ed and Eunice Higgins (a married couple) and Mama (Eunice's mother) would play host to various colorful characters in their home.

"I never wanted to stop and do a retake, because I like our show to be ‘live,’" she wrote in her memoir, as reported by Showbiz Cheat Sheet. "So when the ‘Family’ sketches came along, I was adamant that we never break up in those scenes, because Eunice, Ed, and Mama were, in an odd way, sacred to me. They were real people in real situations, some of which were as sad and pitiful as they were funny, and I didn’t want any of us to break the fourth wall and be out of character.”

It was a noble goal, and one that went right out the window—with Burnett leading the way—in a "Family" sketch during the show's final season that ended with the entire cast rolling with laughter.

Inequality has gotten worse than you think.

An investigation by former "Daily Show" correspondent Hasan Minhaj is still perfectly apt and shows that the problem isn't just your classic case of "the rich get richer and the poor get poorer."

The legality of abortion is one of the most polarized debates in America—but it doesn't have to be.

People have big feelings about abortion, which is understandable. On one hand, you have people who feel that abortion is a fundamental women's rights issue, that our bodily autonomy is not something you can legislate, and that those who oppose abortion rights are trying to control women through oppressive legislation. On the other, you have folks who believe that a fetus is a human individual first and foremost, that no one has the right to terminate a human life, and that those who support abortion rights are heartless murderers.

Then there are those of us in the messy middle. Those who believe that life begins at conception, that abortion isn't something we'd choose—and we'd hope others wouldn't choose—under most circumstances, yet who choose to vote to keep abortion legal.
