Health Tablets: 10 Remarkable Breakthroughs in Medicine and Health in 2025

From gene therapies and the development of next-generation drugs to devices and transplants that highlight fundamental changes in personalized and effective treatment, several discoveries in 2025 have given hope for improving quality of life. These breakthroughs matter because they have transformed the means of healthcare delivery, making it more accessible and efficient for mankind. They have shifted the focus from managing symptoms to prevention and cure, potentially saving millions of lives by tackling some of the deadliest diseases effectively.

Here are 10 medical breakthroughs of 2025:

1. Rare genetic disorder treated using CRISPR-based gene therapy

After birth, Baby KJ was diagnosed with a rare, fatal disorder called severe carbamoyl-phosphate synthetase 1 deficiency (CPS1), which affects one in a million babies. The ammonia levels in the blood increase and lead to vomiting, hypothermia, brain swelling, and coma. Scientists used modified CRISPR treatment to repair faulty genes in KJ’s liver. The experimental procedure was successful and enhanced baby KJ’s life expectancy. KJ became the world’s first patient to receive customized gene-editing therapy, developed by the Children’s Hospital of Philadelphia and Penn Medicine.

2. Human embryo implantation in 3D

Researchers have captured real-time 3D images of human embryo implantation into an artificial uterus for the first time. The uterine matrix was created using a collagen-based gel, rich in uterine tissue and proteins required for embryo development. The experiment was conducted on both human and mouse embryos to study the implantation process. Mouse embryos adhered to the surface, whereas human embryos penetrated deeply into the uterine tissue for implantation.

3. Male contraceptive pill YCT-529 passes safety trials

Researchers have long explored the possibility of a safe and reversible male oral contraceptive. They have tested a novel nonhormonal oral contraceptive pill for males, the first of its kind to pass early-phase clinical safety trials in humans in 2025. The daily pill, YCT-529, blocks a vitamin A metabolite from binding to receptors in the testes, which stops sperm production. The effects of the pill are reversible. However, further efficacy studies and larger trials may perhaps open doors for approval.

4. US FDA clears blood tests to help diagnose Alzheimer’s disease

In May 2025, the US FDA approved the first blood test to help diagnose Alzheimer’s disease. This new blood test (Lumipulse G pTau217/ß-Amyloid 1-42 Plasma Ratio) measures the ratio of two proteins in the human plasma - pTau217 and β-amyloid 1-42. The ratio is then linked to the presence or absence of amyloid plaques in the brain and helps in the diagnosis of Alzheimer’s disease. The test is rapid, highly accurate, and less expensive and invasive compared to the previously available tests. The test can be made highly accessible as primary care providers can now start the diagnostic process even at centers where healthcare providers are scarce. In October 2025, the US FDA approved a second blood test, Elecsys pTau181 plasma test, developed by Roche, that helps rule out the presence of amyloid plaque.

5. Gene therapy for Huntington’s disease shows promise

Huntington’s disease is a genetic neurodegenerative disorder where the brain cells are destroyed persistently, eventually leading to paralysis, dementia, or even death. This condition is caused by a single inherited gene mutation, which causes misfolded proteins to gather in brain cells. But a new gene treatment to disable the toxic protein, injected into the most affected part of the brain, has proven to slow down the progression of the disease. This paves the way for the first-ever treatment for this rare inherited brain degeneration.

6. Vaccines for dementia show potential

Large-scale studies in 2025 from the University of Oxford, NIHR, Stanford, and others suggest some vaccines, such as those for shingles, respiratory syncytial virus (RSV), influenza, pneumococcus, and Tetanus-Diphtheria-Pertussis (Tdap or DPT), can lower the risk for developing dementia. Researchers emphasize that more controlled trials are required to confirm the efficacy of these vaccines.

7. The first successful bladder transplant in a human

In a groundbreaking achievement, a 41-year-old became the first human to receive a urinary bladder transplant. After a tumor removal, his bladder was too small and functionally compromised, and both his kidneys had to be removed due to renal cancer. A donor’s kidney and bladder were transplanted. Postoperative evaluation confirmed adequate urine drainage of the transplanted bladder. Bladder transplantation involves joining a complex network of blood vessels and nerves. The surgery was done to test the viability of bladder transplants in people suffering from terminal kidney and bladder-related diseases. This surgery marks a major milestone in urology.

8. Gene-edited pig liver transplant functions inside a human for 10 days

In 2025, the world witnessed the first-ever xenotransplantation into a brain-dead human. The modified pig liver functioned for 10 days without rejection, which opened doors for a new era of organ transplantation. This achievement also brings hope for solving the organ-shortage crisis. Researchers used a Bama miniature pig liver with six-gene edits, with the recipient’s left liver intact, and simultaneously monitored the vitals, like bile production, for 10 days. The result showed potential compatibility of animal organs as a “bridge” or support organ for patients awaiting human donors.

9. New advancements in mRNA technology

mRNA vaccines became well-known during the COVID-19 pandemic. These are now being tested in hundreds of clinical trials for conditions such as the flu, HIV, genetic disorders, and cancer. mRNA vaccines use a synthetic immunization strategy using genetic codes rather than live-attenuated or inactive viruses to trigger an immune response. The main advantages include rapid design, no need for cell cultures, high immunogenicity, strong safety profiles, and adaptability to various pathogens. Early results from several studies are encouraging. A recent study confirmed that mRNA-based HIV vaccines can trigger the production of neutralizing antibodies, which are essential for protecting cells from infection. While these innovations suggest that mRNA technology could be a powerful weapon against various diseases, larger-scale clinical trials are still necessary to determine its long-term effectiveness and safety.

10. Smallest artificial heart implanted in a 7-year-old

In a breakthrough for pediatric medicine, Chinese surgeons successfully implanted the world’s smallest artificial heart into a 7-year-old boy suffering from end-stage heart failure. Donor hearts for children are extremely rare, and adult-sized implants are often too large to be safe. This miniature device, weighing only 45 grams, fills a critical gap in care. The 2.9-centimeter device uses magnetic equipment to help the heart pump blood. The boy showed immediate signs of improvement after the surgery, proving that these tiny, high-tech devices can provide a vital lifeline for children who have run out of other options.
