Plus, how a new wave of South African romcoms is reimagining Johannesburg. Listen to episode 17 of The Conversation Weekly podcast.
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.
Researchers made human-monkey chimeras, by adding human stem cells to monkey embryos. Some embryos were cultured for 19 days after fertilisation.
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.
Next, researchers want to grow the tear glands of a crocodile – seriously.
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.
How a seaweed extract could help treat type 1 diabetes.
New treatment for osteoarthritis works in sheep and mice. Hopefully, human trials will start soon.
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.
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.
Animals that pause their pregnancies could help us learn valuable lesson about human pregnancy, and even unlock secrets to stem cells and cancer.
We worry about AI developing consciousness, but brain organoids may be more likely to do so.
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.
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.
Tissue engineering and regenerative medicine is based on three key requirements working together: signals from body tissues and organs, responding stem cells, and scaffolds.
Headlines around the world declared that a second person was cured of their HIV. But while the results are encouraging, we’re a long way from a cure.
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.
A large trial to test whether rebooting the immune system will help patients with Crohn’s disease has just begun.
Figuring out what causes diseases like autism, schizophrenia and depression is tricky. Now Stanford University researchers are turning blood into brain cells to study these diseases in a dish.
‘Mini brains’ can be grown in the lab, and brains of decapitated pigs were recently ‘kept alive’ for a day and a half. But what makes a conscious brain?
