Deepfakes – essentially putting words in someone else’s mouth in a very believable way – are becoming more sophisticated[1] by the day and increasingly hard to spot. Recent examples of deepfakes include Taylor Swift nude images[2], an audio recording of
Human brains and fruit fly brains are built similarly – visualizing how helps researchers better understand how both work
The human brain contains approximately 87 billion neurons[1]. On average, each of these cells make thousands of different connections to facilitate communication across the brain. Neural communication is thought to underlie all brain functions – from

The hidden risk of letting AI decide – losing the skills to choose for ourselves
As artificial intelligence creeps further into people’s daily lives, so do worries about it. At the most alarmist are concerns about AI going rogue[1] and terminating its human masters.
But behind the calls for a pause on the development of AI[2] is a
A young Black scientist discovered a pivotal leprosy treatment in the 1920s − but an older colleague took the credit
Hansen’s disease, also called leprosy[1], is treatable today – and that’s partly thanks to a curious tree and the work of a pioneering young scientist in the 1920s. Centuries prior to her discovery, sufferers had no remedy for leprosy’s debilitating
Personalized cancer treatments based on testing drugs quickly leads to faster treatment, better outcomes
Despite many efforts to find better, more effective ways to treat cancer, it remains a leading cause of death by disease[1] among children in the U.S.
Cancer patients are also getting younger. Cancer diagnoses among those under 50 has risen by about 80%
Newly discovered genetic variant that causes Parkinson’s disease clarifies why the condition develops and how to halt it
Parkinson’s disease is a neurodegenerative movement disorder that progresses relentlessly[1]. It gradually impairs a person’s ability to function until they ultimately become immobile and often develop dementia. In the U.S. alone, over a million people are
