Uh oh: AI Amplifies False Memories
According to researchers from MIT and the University of California, Irvine, conversational AI powered by large language models can significantly amplify the creation of false memories in humans, raising concerns about the use of AI technologies in sensitive contexts such as witness interviews.
AI affects human memories primarily through the induction of false memories, particularly in contexts where conversational AI, such as chatbots, is involved. Research indicates that interactions with generative AI models can significantly amplify the formation of false memories. For instance, a study found that participants who interacted with a generative chatbot were nearly three times more likely to develop false memories compared to a control group, and approximately 1.7 times more than those exposed to misleading survey questions. This effect persisted over time, with 36.8% of responses being misled as false memories even one week later
Wonderdrug: Ozempic May Now Delay Aging
Recent studies suggest that Ozempic, a drug primarily used for treating Type 2 diabetes and obesity, may have potential anti-aging benefits beyond its intended use. According to researchers, the active ingredient semaglutide could slow down biological aging by reducing inflammation and lowering the risk of age-related diseases.
Phew: Mobile phones not linked to brain cancer, biggest study to date finds
What did the recent study commissioned by the World Health Organization conclude about mobile phones and brain cancer?
The study, which analyzed 63 observational studies from 1994 to 2022, found no significant link between mobile phone usage and brain cancer or other cancers of the head and neck. The lead author, Ken Karipidis, stated that the evidence does not suggest any correlation, even with prolonged usage or high call volume.
How did the researchers assess the evidence regarding mobile phones and cancer?
The researchers conducted a systematic evaluation of over 5,000 studies, selecting only the most scientifically robust ones. They focused on various cancers affecting the central nervous system and noted that despite the increase in mobile phone usage, brain tumor rates have remained stable.
What previous concerns existed regarding mobile phones and cancer risk?
Initial concerns arose from early studies that compared individuals with brain tumors to those without, which were criticized for potential bias. The International Agency for Research on Cancer (IARC) had classified radio-frequency fields from mobile phones as a possible carcinogen in 2011, but this classification was based on uncertain harmful effects, similar to other agents like aloe vera
