The patient is faring well nearly three years later, thanks to the life-saving device

In 2025, researchers watched an interstellar comet, learned about human origins and traced the spread of measles.

The Ten Most Significant Science Stories of 2025, From Medical Breakthroughs to an Interstellar Visitor

All year long, these moments captivated the public, demonstrated dangerous trends, and pushed research and innovation forward

A team of doctors at NYU Langone transplanted a pig kidney into a brain-dead patient and reversed its rejection twice during the 61-day study.

Scientists Reverse Human Rejection of Pig Organ Transplant for First Time

A new study reversed transplant rejection twice, uncovering the reasons for transplant rejection on a cellular level

Tim Andrews and his wife leave the hospital after he received the pig kidney transplant about nine months ago.

Pig Kidney Transplant Removed From Patient After a Record-Breaking 271 Days

Tim Andrews was the fourth patient in the United States to receive a pig kidney transplant. He will now return to dialysis and wait for a kidney from a human donor

The liver came from a genetically modified cloned pig with ten gene edits.

Surgeons in China Perform First Pig Liver Transplant in Human Patient

The patient lived with part of a pig liver for 38 days before surgeons removed it, surviving 171 total days after the procedure

Scientists converted a Type A kidney to a Type O kidney, then transplanted it into a brain-dead patient.

New Research

Scientists Converted a Kidney’s Blood Type, Then Implanted It Into a Brain-Dead Patient for the First Time

This area of research is still in the early stages, but it could someday help reduce wait times for patients needing kidney transplants

Nobel Committee Secretary-General Thomas Perlmann addresses journalists during an October 6 press conference announcing the 2025 Nobel Prize in Physiology or Medicine in Stockholm, Sweden.

Trio of Researchers Awarded Nobel Prize for Groundbreaking Discovery of Immune Cells That Prevent Autoimmune Disease

Mary Brunkow, Fred Ramsdell and Shimon Sakaguchi’s research revealed a new class of cells shaking up scientists’ understanding of the human immune system

Developed by Australian biomedical engineer Daniel Timms, the titanium heart device is being used as a stopgap until patients can undergo transplant surgery with a donor heart.

Australian Man Makes History by Living With a Titanium Heart for More Than 100 Days Before Receiving a Transplant

The man, who was in his 40s and suffering from severe heart failure, was also the first person to leave the hospital with a titanium heart. He is recovering well after getting a new, donor heart

Transplanting pig organs into people may soon become routine.

The Future of Transplanting Pig Organs in People

After years of research into xenotransplantation, the field is at a turning point—yet risks and ethical issues remain

Towana Looney's surgery at NYU Langone Health lasted seven hours and involved dozens of medical professionals.

An Alabama Woman Got a Gene-Edited Pig Kidney Transplant. Three Weeks Later, She Has ‘Never Felt Better’

On November 25, 53-year-old Towana Looney became just the third living person to receive a pig kidney in an experimental procedure

The 3D bioprinter at the Collins BioMicrosystems Laboratory at the University of Melbourne.

New 3D Bioprinter Could Build Replicas of Human Organs, Offering a Boost for Drug Discovery

The invention uses light, sound and bubbles to quickly create copies of soft tissue that might one day support testing individualized therapies for cancer and other diseases

Two comb jellies have fused together and are being probed by a pipette.

These Frankenstein-Like Sea Creatures Can Actually Fuse Their Bodies Together

Two comb jellies can merge their digestive and nervous systems and even sync their bodily functions, according to new research. The discovery could have implications for human medicine

To create mouse-rat "chimeras," researchers injected rat stem cells into mouse embryos that lacked some genes for brain development.

Researchers Breed Mice With Hybrid Brains Containing Cells From Rats

In one experiment, rat neurons helped mice restore their senses of smell—the first time any animal has perceived the world through the sensory hardware of another species

Doctors perform a pig kidney transplant on April 12. So far, the patient is recovering well, but doctors will need to continue to monitor her in the hospital and make sure her immune system doesn't reject the transplanted organ.

Second Patient Receives Gene-Edited Pig Kidney Transplant in Breakthrough Surgery

The woman, 54-year-old Lisa Pisano, also received a mechanical heart pump implant days earlier, making her the first person to undergo both procedures

Preserved brains tend to look like normal brains, but they're often one-fifth of the typical size.

Archaeologists Keep Finding Preserved Human Brains. But How Do the Organs Remain Intact?

Scientists have unearthed more than 4,400 human brains—some more than 12,000 years old—making them less rare than thought, a new study finds

Volunteers from the John Cage Organ Foundation conducting an earlier chord change in October 2013

This Organ Is Playing a 639-Year-Long Song. It Just Changed Chords for the First Time in Two Years

The instrument has been playing composer John Cage’s “ASLSP” since 2001—and it’s scheduled to conclude in 2640

In the new study, long-tailed macaques, or crab-eating macaques, received kidney tranplants from genetically edited pigs. One of the monkeys survived for just over two years after the transplant.

Monkeys With Transplanted Pig Kidneys Survive for Up to Two Years

The study brings scientists one step closer to conducting trials in human patients, researchers say

Scientists inserted human stem cells in pig embryos that couldn't develop kidneys, then let these embryos gestate in sows for several weeks. The experiments resulted in kidneys partly made of human-derived cells.

Scientists Grow Part-Human Kidneys in Pig Embryos for Nearly a Month

The new work is a “big step forward” in finding new ways to generate viable organs for human transplants, but it comes with some ethical considerations
