“Don’t die for the next 10 years.”
It sounds like an outrageous thing for a scientist to tell us. But Derya Unutmaz, an immunologist and ageing researcher, believes the next decade could bring advances in AI, biotechnology and medicine that fundamentally change how long, and how well, humans can live.
He goes further. If you make it through the next 10 years, he says, you may make it another five. And if you make it 15, the advances could be so profound that humans could gain another 50 years.
Others in the longevity field are making similarly extraordinary predictions about what could be achieved in the next five to 10 years.
The rapid advances in medicine are already turning some things that would have seemed miraculous a decade ago into real possibilities.
Even Elon Musk has reached for biblical language to describe where the technology could go. Speaking about Neuralink’s ambitions to restore movement and sight, Musk called them “Jesus-level technologies” and “miracles of science.”
That may sound like science fiction, but the remarkable thing is that some of the medicine that would once have sounded like science fiction is already being tested in human beings. People who would once have been told there was nothing more doctors could do are being offered new possibilities.
Much of the science remains experimental, and some of the technologies are available only to a small number of patients. However these developments show that rather than just treating the consequences of disease, scientists are now trying to repair, retrain or replace the body's own machinery.
Here are seven of the latest and most remarkable examples, several of which reached important milestones this month.
1. The cancer vaccine made for one person
For years, a “cancer vaccine” sounded like too far out of reach. Now one has crossed an important threshold.
Reuters reports that Moderna and Merck's personalised mRNA vaccine met its main goals in a late-stage trial involving more than 1,000 people with high-risk melanoma whose tumours had been removed.
Used with Keytruda, it reduced the risk of the cancer returning or spreading. What makes it different is that it is made for the individual patient, and not a treatment for millions as has been the case before. Scientists analyse mutations in their tumour and design a vaccine to teach the immune system to recognise those particular cancer cells.
For patients, the hope is simple: what if it comes back? The vaccine could now help the immune system stand guard.
2. The blind are beginning to see again
A tiny retinal implant called PRIMA is giving some people who have lost central vision a chance to see again.
The device is placed underneath the retina in people with advanced geographic atrophy, a severe form of age-related macular degeneration. Special glasses send images to the implant, which converts them into electrical signals for surviving retinal cells.
A clinical trial found that 26 of 32 participants assessed after 12 months achieved a meaningful improvement in visual acuity.
It is not normal sight, and patients must learn to use the system. But being able to see letters, objects or shapes that were previously invisible can be life-changing.
3. The artificial heart that can stand in for the real thing
The French-developed Aeson artificial heart is designed to replace the pumping function of a failing human heart.
Unlike a simple mechanical pump, it uses sensors and controls to adjust blood flow as a person's activity changes.
The device is currently being studied as a bridge to transplantation for people with severe biventricular heart failure.
Engineers have spent years trying to reproduce something the human body does automatically: changing how much blood the heart pumps while we rest, walk or exercise.
For someone whose heart can no longer do its job, Aeson offers something extraordinary, a functioning artificial heart while they wait for a donor.
4. The attempt to make an old cell young again
This may be the most provocative experiment of the seven, and talks to some humans wish to live forever.
In 2026, the first patient entered a Phase 1 clinical trial of ER-100, a therapy designed to partially reprogramme cells and restore characteristics associated with a younger biological state. The first target is the eye, in conditions including glaucoma and non-arteritic anterior ischaemic optic neuropathy. Life Biosciences announced that the first patient had been dosed in the trial.
The science is associated with the longevity research of Harvard geneticist David Sinclair, but the experiment is not a test of whether a whole human being can become younger.
It is a much narrower and more important scientific question: can damaged cells be persuaded to function more like younger cells?
As of now, nobody has reversed a person's age or turned a 70-year-old into a 30-year-old. This is a Phase 1 trial, primarily concerned with safety. But the experiment tests whether some of the damage we call ageing is not irreversible.
Scientists have been studying whether it is possible to reset some of the molecular instructions that tell a cell how to function without completely erasing what kind of cell it is. For decades, that idea belonged largely to the laboratory, now a person has received the treatment.
Many want to know if humanity will live forever, but right now scientists are seeing whether damaged cells in the eye can be made to function better.
If the answer eventually proves to be yes, the implications could extend far beyond eyesight. That is why this tiny experiment matters.
5. A deaf toddler receives gene therapy designed to restore hearing
For parents of a child born profoundly deaf, gene therapy is intensely personal.
This year the US Food and Drug Administration has approved Otarmeni, a gene therapy for hearing loss caused by mutations in the OTOF gene. It delivers a functioning copy of the gene to cells in the inner ear.
And this week came the kind of story that makes a complicated scientific development suddenly understandable.
A 16-month-old boy named Everett became the first patient at Boston Children's Hospital to receive the treatment in the United States, according to People. Born with severe hearing loss caused by an OTOF mutation, he had not benefited from conventional hearing aids. His parents travelled to Boston in the hope that the treatment could give him access to sound.
They are now waiting to see what happens.
The science can be described in terms of viral vectors, proteins and mutations but for a family with a baby who cannot hear, it is a simpler longing: will my child hear my voice?
Clinical data behind the therapy have shown hearing improvements in most treated children, although the treatment is new and long-term outcomes will need to be followed carefully.
It is an extraordinary shift because instead of compensating for a genetic defect with a device, doctors can now attempt to correct the biological instructions that caused it.
6. The brain implant that can give a paralysed person a voice
For someone who has lost the ability to speak or move, independence can shrink to almost nothing.
That is why one of the most remarkable developments in medicine may have nothing to do with a drug at all.
A study published in Nature Medicine has demonstrated an intracortical brain-computer interface that can be used independently at home to decode attempted speech and movement into communication and digital control.
The researchers describe it as a step towards restoring naturalistic communication and digital access for people with severe paralysis.
The distinction between a laboratory demonstration and something that works in a person's home is enormous.
A technology that requires researchers to adjust it every few hours is an impressive experiment. A system that can allow someone with severe paralysis to communicate in the ordinary circumstances of daily life is something else entirely.
The field is moving quickly. Scientific American reported this week on a brain-computer interface that allowed two people with paralysis to type at up to 22 words a minute, approaching the speed of texting on a smartphone.
And Neuralink is also advancing its own human programme. Its communication-focused clinical trial, VOICE, was updated on ClinicalTrials.gov on August 21 and is recruiting people with paralysis or ALS.
The technology is not simply “reading thoughts”. It decodes brain signals associated with intended speech or movement.
For people who have lost the ability to communicate, that could mean something priceless: independence.
It however, also raises a new set of questions, including how brain data should be protected and what laws and safeguards are needed as the technology develops.
7. Medicine is beginning to edit the instructions themselves
The deeper story connecting these breakthroughs is the rise of therapies that intervene much closer to the source of disease.
Gene therapy is no longer an experimental curiosity. The FDA has approved dozens of gene and cell therapies in the United States, covering inherited diseases, cancers and other serious conditions.
Medicine has traditionally been remarkably good at managing disease and much less capable of correcting its origins.
A child with a genetic disorder could spend a lifetime taking drugs to compensate for a missing protein. A person with cancer could undergo surgery, chemotherapy or radiation to destroy malignant cells. Someone losing their sight might be given tools to help them live with what has been lost.
The emerging model is different.
1. Find the faulty instruction.
2. Replace it.
3. Retrain the immune system.
4. Reprogramme the damaged cell.
5. Build the missing organ.
It is still early and some therapies will fail. Some will prove too expensive or too difficult to manufacture at scale. Some of the most exciting results announced by companies will not survive the scrutiny of full clinical data.
But there is something undeniably hopeful all of this. For much of human history, medicine's great battle was against infection, injury and the diseases that killed us young. The next battle may be more ambitious. It is the attempt to persuade the human body to repair itself.
And for anyone who can say the name of someone they love when reading about any of these seven breakthroughs, the idea that science can offer hope where there once was none may be the biggest breakthrough of all. - all additional reporting attributed within the story.
