Trying to maximise lives saved will inevitably be contentious and imperfect.
Monaco and Japan have some of the highest life expectancies in the world. But calculating an individual’s life expectancy will require taking data analysis several steps further.
Predicting life expectancy remains in the realm of science fiction, but it may soon be possible. Are we prepared for such information? And who else would benefit from this knowledge?
Researchers are developing artificial wombs as we speak. So we need to talk about the pros and cons before science fiction becomes reality.
Yes, there are pros and cons of this new reproductive technology. But there are many other issues about maternal and child health we need to tackle first.
It may not be science fiction anymore.
We worry about AI developing consciousness, but brain organoids may be more likely to do so.

CRISPR babies may be just the beginning. China has a different take than the West on ethics and how to get ahead in business and other endeavors.
Controversial gene editing should not proceed without citizen input and societal consensus.
A team in the U.S. is said to have safely and effectively altered human embryos. The news is a reminder that citizens must be consulted on developments potentially affecting the future of the species.
There’s still a way to go from editing single-cell embryos to a full-term ‘designer baby.’
The news may have come as a surprise, but it probably shouldn't have. A bioethics expert walks through how big a deal this announcement is – and what we should be considering now.
Supporters outside the now-abandoned case in the British High Court, rallying for infant Charlie Gard to travel to the US for experimental treatment.
The high-profile Charlie Gard case could change the way end-of-life decisions play out around the world.

BCI devices that read minds and act on intentions can change lives for the better. But they could also be put to nefarious use in the not-too-distant future. Now's the time to think about risks.
Scientists have made a massive breakthrough.
What rights should a chimera with human-like cognitive abilities but without the ability to speak have?
A discipline neither good nor evil.

Maybe you think neuroscience has a peaceable history of benign efforts to improve lives and enhance human capacities. But its origins and development tell a different story – with ethical implications.
Cryonics has gone from the world of sci-fi movies to the law courts for the family of one 14-year-old girl.
A UK court has allowed a 14-year-old girl's body to be frozen until doctors find a cure for the cancer that killed her. Is this latest example of cryogenics hope, hype or hell?
Parents’ role as medical decision-makers is sometimes questioned when they don’t choose the recommended treatment for their child.
It is ethical for doctors to accept a treatment option parents want – providing it is good enough – rather than insisting on what they believe is the best possible treatment for the child.
Will China be the first to genetically enhance future generations?
Regulations, funding and public opinion around genetically enhancing future generations vary from country to country. Here's why China may be poised to be the pioneer.
Personalised medicine allows treatment to be tailored to a patient’s unique genetic makeup.
The rise of personalised medicine, which is mainly based on genetic testing, needs adequate regulation so privacy rights aren't breached. That's only one of several issues that must be considered.
