Radically different
I spent nearly a decade leading FDA’s Center for Food Safety and Applied Nutrition. That role convinced me that food safety and nutrition are interdependent in so many ways, and if we want to make our population healthier, we need to support both.
Over the past few weeks, record numbers of cases of cyclosporiasis have driven that message home broadly, including to consumers. FDA is currently investigating six cyclospora outbreaks, only one of which is currently linked to shredded iceberg lettuce.
WASHINGTON — A Food and Drug Administration advisory panel recommended on Friday that compounding pharmacies be allowed to manufacture the peptides epitalon and semax, but narrowly voted to recommend against manufacturing emideltide.
The votes, which followed the panel’s decision on Thursday to recommend allowing pharmacies to make four other peptides, bring health secretary Robert F. Kennedy Jr. one step closer to his mission of making these unapproved compounds more available for Americans. Peptides, which are short-chain amino acids, have become increasingly popular in the U.S., driven by endorsements from social media influencers.
This week, I covered a fascinating effort to preserve organs outside the body. There’s a huge shortage of donor organs, and one of the main reasons is time—they survive only a matter of hours outside the body, even when they’re kept on ice.
Doctors dream of organ banks—stores of human organs that can be preserved for days, weeks, months, or even longer. That would allow them to run tests on organs, find the best matches for them, and transport the organs to those recipients.
In new research, one team has been able to supercool the kidneys of pigs—animals whose organs are of a similar size to human ones—and preserve them for days. The kidneys survived being stored at −4 °C (25 °F) and eventually reimplanted back into pigs. And that’s just the latest development in a field that is positively buzzing.
It has proved super difficult to freeze organs. Once ice forms in them, they’re done. The ice crystals create all kinds of damage and render the organs unusable. That hasn’t stopped many researchers from trying.
Some have focused on cryopreservation—rapid extreme cooling that essentially leaves cells in a glasslike state. This process is now routine for eggs, sperm, and embryos, which are cooled to −196 °C in less than two seconds and can be used even after decades in storage.
No one has managed to cryopreserve and thaw human organs for transplantation. But plenty of human bodies and brains have been stored at ultra-low temperatures in the hope that they might one day be rewarmed and brought back to life. (You can read more about why some people opt for cryonics here.)
In March, I wrote about Stephen L. Coles, a gerontologist who had opted to cryopreserve his own brain. After the scientist died in 2014, his body was taken to Alcor, a cryonics facility in Arizona. A team at the facility removed Coles’s head, perfused his brain with cryoprotective chemicals (which work like antifreeze), removed the brain from the skull, and cooled it to −146 °C.
When Coles’s friend Greg Fahy, a cryobiologist, studied pieces of his brain years later, he found that the brain cells, which had shrunk, “bounced back” once they were rewarmed. But that doesn’t mean the cells are alive, or that it might one day be possible to reanimate the brain. As Matthew Powell Palm of Texas A&M told me at the time: “There are so many ways those neurons could be toast.”
Powell Palm is working on other ways to preserve organs. It was he, along with his colleagues, who managed to store supercooled pig kidneys and successfully transplant them, in a study described as “a landmark achievement.” Those organs did better than kidneys stored on ice, he says.
His approach didn’t require cryoprotectants. But other teams are exploring potential chemical cocktails that might allow them to store organs at lower temperatures, potentially for longer periods of time. (More on this in The Checkup soon!)
Another way to prolong the lifespan of an organ is to use a machine that perfuses it with nutrients, mimicking what happens inside the body. Machine perfusion devices have become more commonly used over the last decade or so and are typically used to maintain livers and kidneys for up to about 24 hours.
Researchers are now adapting this protocol for a growing list of organs, even eyeballs—a recent feat that might enable whole-eye transplants. In March, I went to visit scientists in Valencia who had developed a perfusion system for uteruses. They had used their device—which they nicknamed “Mother”—to keep a human uterus alive for a day.
It’s an exciting time for organ preservation. Keep an eye out for more coverage from MIT Technology Review in the coming weeks.

The number of measles cases in the U.S. has surpassed the record-breaking tally for all of 2025, with five more months of 2026 still to come.
The U.S. Centers for Disease Control and Prevention logged 2,318 cases of measles as of Thursday, according to an agency update on Friday.
Recent conversations about the portrayal of OCD on TLC’s 90 Day Fiancé underscore an important truth: how OCD is portrayed in television, film, and other media matters.
OCD is a serious, often debilitating mental health disorder affecting millions of people. It is characterized by unwanted, intrusive thoughts, images, or urges (obsessions) and repetitive behaviors or mental acts (compulsions) performed in an attempt to reduce distress. While OCD can look different from person to person, it is highly treatable. Yet today, nearly 95% of people with OCD are not receiving the most effective treatment. Misunderstanding OCD makes it harder for people to recognize their symptoms, receive an accurate diagnosis, and get the care they need to reclaim their lives.
Each episode of 90 Day Fiancé is watched by more than one million viewers. With that kind of reach comes an extraordinary opportunity to shape public understanding of mental health for the better. Accurate portrayals of OCD have the power to transform lives. They replace myths with understanding, reduce stigma, help people recognize the signs of OCD sooner, inspire individuals to seek effective treatment, and let those living with OCD know they are not alone—and that recovery is possible.
The entertainment industry has a responsibility to get it right, and doing so requires thoughtful decisions at every stage of the creative process. The International OCD Foundation encourages TLC to engage clinical experts and people with lived experience to better inform their editorial decisions. We stand ready to serve as a resource for future portrayals of OCD and related disorders.
If you are creating content that includes OCD or related disorders, we encourage you to connect with us at media@iocdf.org. Together, we can improve public understanding of OCD, reduce stigma, and help more people find the treatment that can change their lives.
