Research into the vulnerable Iberian lynx reveals surprising insights into its genetic history.
New techniques monitor the health of lakes in real time by analyzing their microbiome to anticipate and respond to environmental threats such as cyanobacteria.
It’s unclear why people chose to live in the caves, but DNA is shedding light on their lives.
You don’t need a fancy qualification for these experiments – just some curiosity and few household basics.
Females have twice as many copies of some genes as males do – and exactly how different species manage this imbalance has puzzled scientists for decades.
Winning a Nobel Prize is a rare achievement, but some researchers have been awarded more than one.
Our research suggests environmental DNA analysis could transform traditional ways of monitoring freshwater ecosystems.
An insect’s physical shape and characteristics indicate which species it belongs to, but sometimes species appear remarkably similar. DNA technologies can help identify and discover species.
Paleontologist Bill Ausich explains whether dinosaurs could ever roam the Earth again. Listen on The Conversation’s Curious Kids podcast.
‘Hervs’ date back hundreds of thousands of years – and play an important role in regulating genes.
Genomic research stands to help develop new medical treatments – and we need donations of lots of data for this to work. But people don’t want data on their genes to be exploited for profit.
The origin of life on Earth is one of the biggest mysteries in science.
Calcite, the material making up fossilized eggshells, may preserve amino acids better than bone.
Genealogical and genetic ancestors aren’t the same thing. A DNA match − or a lack of one − may not tell you what you imagine it does about your family tree.
Just as the world’s zoos breed critically endangered animals in captivity to repopulate the wild, scientists are building a global effort to freeze corals for reef restoration.
Research has revealed how British otters may have been able to recover from species loss in the 1950s with the help of otters from Asia.
Computer analysis of the genomes of extremophiles — organisms that live in extreme environments — reveals that their living conditions are recorded in their DNA.
New research suggests the gut bacteria of red and grey squirrels differ significantly, potentially explaining the decline of the native red and the success of its grey counterpart.
Understanding how the ageing of sperm works in other animals is more important than ever as human male fertility is in decline.
