You can sign up to donate your body to science

You can sign up to donate your organs at this website

A single person who chooses to donate their organs upon death can provide organs for as many as eight people. You can sign up to become an organ donor or update your donation status information at this website, or you can typically sign up at your state's Department of Motor Vehicles. Many states allow individuals to declare which tissues and organs you consent to donate (i.e. organs, eyes, and skin tissue). It's recommended to discuss your decision with your family so they are aware of your wishes.

Brain death is a top source of organ donation

Brain death is a significant source of organ donations—approximately 40% of organs in the US and the UK are recovered from people who experience brain death. Patients declared brain dead and hooked up to intensive care unit machines will still have oxygen flowing to organs like the heart, lungs, and kidneys—preserving those organs.

In the US, you must actively sign up to donate your organs

The US has an opt-in donation system for organ donation—meaning people must provide consent to proceed with any donation. Locations including Spain, the United Kingdom, and Argentina have an opt-out donation system, which means individuals are presumed to be donors unless they actively refuse consent.

The medical profession has a dark history of 'body snatching' for education

This term originally referred to secretly removing corpses from graves for sale—usually to medical schools where they were used for education. The practice dates back at least to the 1300s but still—much more rarely—persists today.

In 2023, at least 6 people were charged with stealing body parts

A recent case involving alleged trafficking in stolen human body parts charged that there was a nationwide network of individuals who bought and sold human remains. The charges alleged, among other things, that from 2018 through 2022, the manager of the morgue at Harvard Medical School's Anatomical Gifts Program stole organs and other parts of cadavers that had been donated for medical research and education. In late 2025, that Harvard morgue manager was sentenced to 96 months in prison.

This Indiana medical school encouraged students to get to know their cadavers' families

The school's anatomy professor instructed medical students to think of the cadavers they worked with as their "first patients"—using their names to acknowledge that this was a person and to exchange letters with the cadaver's family members if they agreed to participate. At the conclusion of the course, families were invited to a lab-based memorial service.

'Human composting' is an eco-friendly burial method legal in only a few states

Formally known as natural human organ reduction, this process relies on the same principles as standard composting and breaks down the body over many weeks, turning it into a type of soil. It's currently only legal in a handful of states.

Some medical schools have phased out human cadavers for digital alternatives

AI-based anatomy tools and digital cadavers are increasingly used to teach students, bypassing the ethical and consent concerns around the use of real bodies. Digital cadavers have also become less expensive than real ones, though the tactile and sensory experiences of real dissection may be irreplaceable.

Brain death is a medical diagnosis without any wiggle room

Seeking to resolve long-standing variations between hospitals and state procedures, in 2023 several expert groups published comprehensive step-by-step guidance for clinicians to follow when determining brain death in kids and adults. Among other guidelines, it stated that doctors don't need to get family consent to do the tests needed to make this determination.

Whose bodies are held inside the American Museum of Natural History?

The American Museum of Natural History holds the remains of at least 12,000 people collected via purchase, donation, or expedition. This article by a professor of art crime details their attempt to identify the individuals whose remains the museum held. Amid questioning, AMNH announced it would change its human remains policy. At the time of the article's publication in October 2023, AMNH had few human remains on public display.

Chinese scientists transplanted a pig lung into a human being—but it had to be removed

In August 2025, Chinese scientists transplanted a pig lung into a brain-dead person, a common research step for this type of experimental work. Researchers used CRISPR technology to alter six proteins in the pig genes to make the organ seem less foreign to the human immune system. Within a day there were indications the organ wasn’t functioning well and that the person’s body was rejecting it. Scientists ended the experiment after nine days.

Why don't we synthesize blood?

We're trying. Scientists are currently working on creating viable synthetic blood, an alternative to the presently relied-upon donations that manage to fall short of demand. More than half of the world's nations struggle to meet their population's need for blood. This article details current and historical efforts to develop synthetic blood, a venture that started more than 400 years ago.

About 70% of the Human Genome Project's reference genome came from one donor

Volunteers who donated blood to the Human Genome Project consented to using no more than 10% of their DNA, raising questions about the project's legality. Listen to how pressure from a private competitor may have driven officials to ignore ethical standards.

How much your blood really costs

In the US, donating plasma twice a week can earn you $400 a month. But this system only works by targeting people who need the money most. Plasma clinics are placed in low-income zip codes, and frequent donation may increase health risks.

How to turn any cell of the body into a stem cell

Scientists have developed techniques allowing them to 'reprogram' any cell in the body into an induced pluripotent stem (iPS) cell, which can be used to create either more stem cells or specialized cells for use in experimental medical treatments. This page gives readers a brief introduction to the history of iPS cells, what researchers are studying with iPS cells, and challenges associated with iPS research.

Research studies can be conducted inside or outside of living samples

While "in vitro" experiments occur outside living organisms for cost-effectiveness, "in vivo" experiments take place inside them, providing real-life insights at a higher cost and with increased ethical concerns. Alternatively, "in silico" methods use computational simulations.

How do brain scans work?

There’s only one thing in our solar system sophisticated enough to study itself: the human brain. But this self-investigation is challenging because a living brain is shielded by skull, swaddled in tissue, and made up of billions of tiny cells. How do we study living brains without harming their owners? Two experts explain how the various techniques like EEGs, fMRIs, and PETs work in this TedEd talk.

Advance genetic research by playing these scientific video games

Computers produce so much information that researchers can’t properly analyze all the data produced, and the overload can also lead computers to make mistakes. Researchers are increasingly turning to citizen scientists—members of the public who are willing to volunteer—to help them make sense of data when computers can’t. This article details a few of the ways you can contribute to genetics research by playing video games.

Explore the abundance of different types of cells in the human body

Lacking a nucleus and other organelles to maximize space for oxygen-carrying hemoglobin and enhance maneuverability through narrow capillaries, there are about four times as many red blood cells and platelets as all other cell types in the body combined. However, about half of the body's cell biomass consists of skeletal myocytes, or muscle fibers.

How does cancer spread through the body?

Cancer usually begins with one tumor, but it can spread to other organs if not removed. This video breaks down how cancer moves to these new areas and why some organs are more likely to get infected than others.
