Lie-detection AI could provoke people into making careless accusations, researchers warn

Although people lie a lot, they typically refrain from accusing others of lying because of social norms around making false accusations and being polite. But artificial intelligence (AI) could soon shake up the rules. Researchers demonstrate that people are much more likely to accuse others of lying when an AI makes an accusation. The finding provided insights into the social implications of using AI systems for lie detection, which could inform policymakers when implementing similar technologies.

The mechanism behind melanoma resistance to treatment

In many cases of malignant melanoma, the effect of targeted treatment is lost over time. A research team has now discovered that a factor secreted by tumor cells is responsible for the resistance. These findings could pave the way for more effective therapies.

Study shows how liver damage from stress and aging might be reversible

While the liver is one of the body's most resilient organs, it is still vulnerable to the ravages of stress and aging, leading to disease, severe scarring and failure. A research team now might have found a way to turn back time and restore the liver. In experiments using mice and liver tissue from humans, the researchers identified how the aging process prompts certain liver cells to die off. They were then able to reverse the process in the animals with an investigational drug.

Brain's 'escape switch' controlled by threat sensitivity dial

Neuroscientists have discovered how the brain bidirectionally controls sensitivity to threats to initiate and complete escape behaviour in mice. These findings could help unlock new directions for discovering therapies for anxiety and post-traumatic stress disorder (PTSD).
