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.
New technology could unlock the soil-enriching nitrogen-fixing ability of legumes…and one day apply this to other crops too.
Many people know someone with a genetic disease, but few understand how gene mutations work.
‘Jaws,’ published in 1974, terrified the public of sharks, but it also brought shark research into the scientific mainstream.
Genetic analysis reveals one of the teenagers probably had advanced gum disease.
We tend to just think of viruses in terms of their damaging impacts on human health and lives. But viruses can also be used to benefit human health, agriculture and the environment.
Did the enormous West Antarctic Ice Sheet collapse the last time global temperatures were 1.5°C above preindustrial levels? The answer lay in the DNA of an octopus.
New research has uncovered the hormone that triggers morning sickness, offering hope for millions of women.
