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.

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?
Only one Canadian researcher has ever received the Nobel Prize for medicine, for the discovery of insulin in 1923. And yet Canadians have been essential to developments in stem cell research, gene sequencing and treatments for cancer and brain trauma. (Shutterstock)

Why can’t Canada win another Nobel Prize in medicine?

Only one Canadian has ever received the Nobel Prize for medicine, in 1923. But Canadian discoveries have been essential to stem cell research, gene sequencing and treatments for cancer.

Private clinics’ peddling of unproven stem cell treatments is unsafe and unethical

Stem cell science continues to offer great promise. But a growing number of clinics are selling treatments without evidence that what they offer is effective – or even safe.
