Just a few millimeters across, organoids are clumps of cells that resemble the brain. Madeline Andrews, Arnold Kriegstein's lab, UCSF

Brain organoids help neuroscientists understand brain development, but aren’t perfect matches for real brains

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.
Currently, stem cell based treatments are still mostly experimental, and while some results are encouraging, several clinical trials have failed. (Shutterstock)

Stem cell treatments: Miracle cures or dangerous experiments?

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 studies suggest medicinal plants can help repair human bone and tissue

Tissue engineering and regenerative medicine is based on three key requirements working together: signals from body tissues and organs, responding stem cells, and scaffolds.

A cure for HIV? Feasible but not yet realized

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.
Marius Wernig, Thomas C. Südhof and their colleagues created these “Induced neuronal (iN) cells” from adult human blood cells. Marius Wernig

Neurons made from blood cells – a new tool for understanding brain diseases

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.

Could this be the year for a Canadian Breakthrough Prize in Life Sciences?

The nomination deadline for science’s most lucrative prize – the Breakthrough Prize – is looming. Why has no Canadian ever received this prize, despite groundbreaking discoveries?
