Scientists are devising human-animal hybrids for harvesting human organs, but lab-derived mini-organs are a less ethically fraught solution to meeting the need for transplantation.

Technology is enabling increasingly lifelike models of organs to help doctors practice operations.

The goal is to house patients’ follicles in a specially designed tissue matrix and reinsert them after treatment.

Scientists engineered a synthetic, nutrient-rich gel that feeds growing organoids as they mature from human pluripotent stem cells into 3-D bowels.

Tissue recipients were treated as “guinea pigs,” says investigation leader.

Researchers have constructed prosthetic female reproductive organs and implanted them in mice, some of which conceived and gave birth to live young.

The embattled thoracic surgeon blames his former employer, the Karolinska Institute, for losing data related to the retracted research.

This year’s list of winners celebrates both large leaps and small (but important) steps in life science technology.

Researchers create an artificial nerve that could be the forerunner of neural prosthetics.

The federal agency publishes a brief note alleging another ethical breach by former Karolinska Institute researcher Paolo Macchiarini.

Colleagues of the surgeon under investigation distance themselves from a 2011 The Lancet study.

The embattled artificial organ researcher has been dismissed over the fallout from several misconduct allegations leveled against him.

A whistleblower asked to have his named pulled from a study led by the embattled surgeon.

Vice-Chancellor Anders Hamsten is resigning from his post amidst another investigation into the work of surgeon Paolo Macchiarini.

Paolo Macchiarini will again be investigated by the Karolinska Institute, which is not extending the researcher’s employment contract.

Is there room to improve upon the tried-and-true, decades-old technology of artificial hearts?

Texas Heart Institute heart surgeon Bud Frazier is a pioneer of heart transplant technologies.

A new flexible sensor can detect touch and generate electrical pulses that signal intensity of pressure to mouse neurons in vitro.

The Karolinska Institute has rejected the conclusions of an earlier, independent investigation, finding regenerative medicine researcher Paolo Macchiarini not guilty of scientific misconduct.
