It took years of attempts before scientists were able to clone a mammal from an adult cell. And with that success came plenty more questions.
Although genomics research has the potential to revolutionize medicine, it has limitations. It may not do much to prevent many of the leading causes of death.
A report released by the US National Academies of Science and Medicine underscores the potential of gene editing and acknowledges the sensitivities in managing the ethical dimensions.
When politics meddles with science, it can lead to tragedy, as was the case with Stalin’s favourite agricultural biologist Trofim Lysenko and his rival Nikolai Vavilov.
Up to 50% of the people who take the efavirenz antiretroviral react particularly badly to it and need to change drug regimens.
New regulations for research with human blood and tissue try to balance scientific progress with patient privacy.
A cryptic part of DNA helps keep a species’ mutations in check until they become useful.
Scientists have sequenced the seahorse’s genome and found the genes that could explain male pregnancy.
Medical tourism for assisted reproductive technologies raises a host of legal and ethical questions.
Illuminating the origins of one of the oldest peoples in the Middle East.
Educational genomics could mean tailor-made curriculum programmes can be created based on a pupil’s DNA profile.
After almost four-and-a half decades and from modest beginnings, the Dunedin study has evolved into one of the most significant long-term tracking studies in the world.
Gaining a better sense of what genes are involved in regulating circadian clocks could put us on a path to find better treatments and therapies to help people adjust to time shifts.
The two species mated 500,000 years ago, leaving a genetic mark to this day. This knowledge could help save them from extinction.
Every single Cavendish banana plant worldwide is genetically identical. This vast monoculture sets them up for disastrous disease outbreaks. But researchers have ideas on how to protect the crop.
Overweight women have a higher risk of delivering biologically older babies who are are more susceptible to age-related conditions such as heart disease and type 2 diabetes in later life.
Your child may have the fussy-eater genes, but they should still try different foods.
Testing some genes for Alzheimer’s disease, coeliac disease and folate conversion does not lead to improved health outcomes, and may create anxiety or false hope amongst patients.
Wildlife in wilderness areas have more genetic diversity, which is better for their survival.
