Fish leave bits of DNA behind that researchers can collect.

Animals shed bits of DNA as they go about their lives. A new study of the Hudson River estuary tracked spring migration of ocean fish by collecting water samples and seeing whose DNA was present when.
Professor Kasimir Popkonstantinov and the marble reliquary that potentially held John the Baptist’s bones.
Here's what DNA analysis of relics purported to be from Jesus or his family can actually tell us.
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 potential anti-ageing drug is likely to be more effective at maintaining health than extending lifespan.
The true promise of ageing research is that rather than tackling individual diseases one at a time, a single drug to treat ageing would treat all of the diseases that arise in old age, at once.
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.
Cells within corn kernels have properties similar to those within human blood cells.
A gene controlling cell identity in corn kernels is the same one that controls progression to specific cancers in humans. Here's why.
Dental calculus deposits show this Neadertal was eating poplar, a source of aspirin, and moulded vegetation including Penicillium fungus, source of a natural antibiotic.

Neanderthals had a very varied diet based on what foods were available to them where they lived. They also knew what to eat when they were sick.

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.
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.
A cryptic part of DNA helps keep a species' mutations in check until they become useful.
There are more than a million Druze worldwide, with the vast majority residing in the Middle East.
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.
The egg collected in the Central Tanami Desert, Northern Territory, in October 1983.
For more than three decades an egg found in a remote Australian desert was thought to be from a rare nocturnal parrot. So what happened when scientists decided to double-check?
New research shows a high BMI in mothers before pregnancy may impact the health of their child.
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.
Cave artists knew about the elusive bison some 17,000 years ago.
DNA analysis suggests that a newly discovered species of bison roamed Europe some 17,000 years ago - as prehistoric cave artists were trying to tell us all along.
Cell nucleus with RNA.
Aging and cancer appear to be closely linked, as over time, cells accumulate hits in their DNA code. But now research has turned to the role of RNA. Is RNA the key to a longer life?
A fun game, plus science advancement.
We recently set up a Foldit competition between gamers, undergraduate students and professional scientists. The winner might surprise you – and offer important possibilities for scientific research.

It's a landmark case but there are many unknowns.
Professor Eske Willerslev talks to Aboriginal elders in the Kalgoorlie area in southwestern Australia.

New DNA research working with Indigenous Australians is answering many of the questions about when and where the First Australians emerged many thousands of years ago.
