Our cells have a built-in genetic clock, tracking time… but how accurately?

How do scientists figure out when evolutionary events – like species splitting away from a common ancestor – happened? It turns out our DNA is a kind of molecular clock, keeping time via genetic changes.
A new study shows cephalopods edit messages from their DNA, allowing them to adapt faster to their environment.

A field called epigenomics looks at chemical modifications that do not change our DNA sequence but can affect gene activity. What are the limitations, and can biomedicine use this to our advantage?
The court found that parents have a strong interest in a "genetic affinity" with their children, one that can merit compensation if subverted.
The discovery of a rare gene is twofold, and has a scientific and clinical impact in the fight against heart muscle disease.
How does one set of genes result in huge horns in males and none at all in females?
How can the same basic genome produce such different forms in the two sexes of a single species? It turns out one gene can encode for various things, depending on the order its instructions are read.
Genetic testing has many touted future benefits - but are any of them coming to fruition?
Over $US3 billion is spent every year on genetic research. But we are not getting enough return for this investment.
Chronic pain can be disabling.
Chronic pain often comes with other illnesses. Researchers have now shown that genetics can play a part in how likely you are to suffer.
Well hello, Dolly.

In 1997, scientists announced they'd created a healthy sheep cloned from another ewe's mammary gland cell. Two decades on, the technique is being refined and applied to new challenges.

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.
What could genomic medicine do in the future?

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.
Gene therapy is growing in its capabilities, but there should be limits to its use.
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.
In Soviet Russia, the science tests you.
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.
People with a certain gene have an adverse reaction to the antiretroviral efavirenz.
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.
