Scientists in Britain have used gene-editing techniques to stop bird flu spreading in chicken cells grown in a lab - a key step towards making genetically-altered chickens that could halt a human flu pandemic.
Teenagers in the US coastal state of North Carolina who were schooled in the basics of man-made climate change saw their parents grow more concerned about the issue, scientists say in the first study of its kind.
Scientists at the Ohio State University in the US have discovered a new species that lived more than 500 million years ago — a form of ancient echinoderm that was ancestral to modern-day groups such as sea cucumbers, sea urchins, sea stars, brittle stars and crinoids.
Harnessing a probe used to image the brain in diagnosing Alzheimer's disease and related forms of dementia, scientists at Dana-Farber Cancer Institute and Massachusetts General Hospital (MGH) have successfully cleared patient-derived brain cells of an abnormal protein associated with dementia and other neurogenerative disorders.
The genetic and molecular makeup of breast tumors holds clues to how a woman’s disease could progress, including the likelihood of it coming back after treatment, and in what time frame, according to a Cancer Research UK-funded study published this week in the journal Nature.
