While a strong immune response is essential to fight against viral infection, an immune system that continues to stay active long after the virus has been cleared can lead to lung damage.

The International Society for Stem Cell Research’s newly released guidelines aim to address new ethical challenges posed by stem cell advances such as model embryos and human-monkey hybrid embryos.
Medical research to benefit people is first conducted in animals. Creating a new biomedical model by inserting human immune cells into pigs may lead to new insights and treatments.
The tear glands were cultured as ‘organoids’ in a Petri dish.

New strategy helps build synthetic organs from scratch. This enabled the researchers to grow functioning liver tissue in the lab that could be transplanted into mice with liver disease.
Brain organoids are tiny models that neuroscientists use to learn more about how the brain grows and works. But new research finds important differences between the model and the real thing.
The groundbreaking Xenobots were created by a team from Tufts University and the University of Vermont.

Xenobots have been called the world’s first “living robots”. They are made entirely of living tissue, and can be programmed to move towards a certain object.

We worry about AI developing consciousness, but brain organoids may be more likely to do so.
Currently, stem cell based treatments are still mostly experimental, and while some results are encouraging, several clinical trials have failed.

Stem cells show much promise, both for testing drugs and for treating disease. But the hype around them has been dangerous, as most treatments are in very experimental stages and can cause harm.
Lab-grown organs may not be so easy to transplant into a patient.

The idea behind regenerative medicine is that the patient is both the donor and recipient of healthy tissue grown from stem cells. But sometimes the transplanted cells are rejected. Now we know why.
Eucomis autumnalis is more than just a plant - it could play a role in biomedical engineering.

Tissue engineering and regenerative medicine is based on three key requirements working together: signals from body tissues and organs, responding stem cells, and scaffolds.
The human immunodeficiency virus (HIV), shown here as tiny purple spheres, causes the disease known as AIDS.

Dangerous open wounds known as cutaneous ulcers are common in people with diabetes and bedsores. Now scientists have figured out how to reprogram the cells inside these wounds to heal themselves.
