A novel AI-powered study explores evolutionary differences between male and female birdwing butterflies, shedding new light on a historic debate between Charles Darwin and Alfred Russel Wallace. Using machine learning to analyze over 16,000 butterfly specimens, researchers found that both sexes contribute to species diversity.
A new neuroprosthetic interface allows prosthetic limbs to be controlled by the body’s nervous system, resulting in a natural walking gait. The surgery reconnects muscles, providing proprioceptive feedback, enabling users to walk faster and navigate obstacles more effectively.
New research shows that we can distinguish between accurate memories and those filled with general knowledge. A study revealed that when memories are based on ‘prototypical’ information, our confidence in them decreases. This awareness helps us accurately assess the reliability of our recollections. These findings have significant implications for the credibility of eyewitness accounts in […]
A new study reveals sex differences in how the brain’s reward pathways function, specifically in the hippocampus and nucleus accumbens. Males and females use different molecular mechanisms to strengthen these connections, influencing responses to treatments for disorders like depression and substance abuse. The findings highlight the need for more gender-specific research to develop effective therapies. […]
A new study reveals that misleading information about depression is widespread, making it harder for people to grasp the causes of their distress. The study criticizes the circular reasoning used in psychiatric diagnoses, noting that depression is often incorrectly presented as a disorder that causes symptoms rather than a description of them. This misrepresentation is […]
Researchers have found that sleep deprivation can hide, rather than erase, memories in mice, and that these memories can be restored using existing drugs. The study demonstrated that roflumilast, an asthma medication, could recover social memories, while vardenafil, an erectile dysfunction drug, restored spatial memories.
Researchers have enhanced auditory processing in young mice by increasing inner ear synapses using neurotrophin-3. This study supports the hypothesis that synapse density impacts hidden hearing loss in humans. The findings could lead to new treatments for hearing disorders by preserving or regenerating synapses. The study reveals that boosting synapses not only improves hearing but […]
A new study reveals that using digital devices to manage children’s tantrums hampers their ability to regulate emotions later in life. Researchers found that frequent use of tablets or smartphones for calming children results in poorer anger management skills.
A new study reveals a 1250% increase in Google searches for microdosing from 2015 to 2023, driven by relaxed regulations on cannabis and psychedelics. The research shows policy changes correlate with growing interest in microdosing, filling gaps in understanding substance use trends.
Researchers discovered the serotonin 2C receptor in the brain plays a crucial role in regulating memory in both humans and animal models. This breakthrough offers insights into conditions associated with memory loss, such as Alzheimer’s disease, and suggests new treatment pathways.
