A man sits outside and holds a slim menthol cigarette between his fingers. Close-up with focus on the cigarette. The study provided a comprehensive examination of how lifestyle and environmental ...

Not everyone needs 8 hours of sleep to function properly. Some people can feel well-rested and show no negative effects of sleep deprivation, even after just 4 hours of sleep, which is likely the ...

Biology has clever ways to mask the effects of potentially harmful gene mutations. Scientists are investigating how this ...

In genomes, three letters or bases of DNA encode an amino acid. Amino acids are then strung together by the cell to create proteins. There is some redundancy in that genetic code, but there are single ...

Individuals that share the same deletion of a portion of chromosome 16 are at risk of developing neurodevelopmental disorders, but some experience severe intellectual disability or developmental delay ...

Health Sleep Rare genetic mutation lets some people thrive on just 4 hours of shut-eye A newly identified mutation helps super-sleepers get by on just four to six hours of shut-eye per night, while ...

An estimated 170,000 Australians were diagnosed with cancer in 2025. Many people know the causes of cancer are partly genetic. But how do your genes, which contribute so much of what makes you you, ...

Scientists have revealed parts of the genome that are especially vulnerable to mutations that occur very early on in development. These areas are in the initial portions of genes, where the cell tends ...

Genes are short sections of DNA that determine an animal’s traits—everything from coat color and claw strength to body shape and health. But sometimes, these genes mutate. And while the word itself ...
