Blood sugar patterns and dietary choices play a significant role in how well adults sleep. Individuals with diabetes were more likely to experience sleep disorders, poor sleep quality, and irregular sleep duration, with people who have...
Scientists exploring how the brain responds to stress discovered molecular changes that can influence behavior long after an experience ends. They also identified natural resilience systems that help protect certain individuals from...
A new analysis suggests that people with type 2 diabetes who use GLP-1 medications like Ozempic, Trulicity or Victoza may be less likely to develop epilepsy than those taking DPP-4 inhibitors. Semaglutide showed the strongest connection...
Researchers have developed an AI-driven brain model that can track fear as it unfolds in real-world situations, offering a major shift from traditional lab-based approaches. Classic fear studies often rely on static images, but these do...
New research shows that blood from older animals can speed up Alzheimer’s-related changes in the brain, while young blood may slow them down. In a long-term experiment, mice engineered to develop Alzheimer’s symptoms received weekly...
There are two small moons in orbit around Mars today, but both may be remnants of a much larger moon that had enough of a gravitational pull to drive tides in the Red Planet's lost lakes and seas
Controlling qubits with quantum superpositions allows them to dramatically violate a fundamental limit and encode information for about five times longer during quantum computations
Neisseria gonorrhoeae, the microbe responsible for gonorrhoea, is developing resistance to most antibiotics, which means we need new drugs to treat the condition. An antibiotic called zoliflodacin might be part of a solution
A new study shows that precisely manipulating brain activity during sleep can help mice retain memories that would normally fade, offering a potential pathway for treating memory loss conditions. Researchers identified a specific...
New research shows that rats with naturally higher baseline stress hormone levels are significantly more likely to self-administer cannabis vapor. Over several weeks, rats were allowed to nose-poke for cannabis, and those with elevated...
New research reveals that even a small loss of myelin—the protective coating around neurons—can severely disrupt how the brain sends and interprets sensory information. Studying corticothalamic circuits in mice, scientists found that...
In a stunning reversal, Disney has changed tack with regard to safeguarding its copyrighted characters from incorporation into AI tools – perhaps a sign that no one can stem the tide of AI
Rats with naturally high stress levels were far more likely to self-administer cannabis when given access. Behavioral testing showed that baseline stress hormones were the strongest predictor of cannabis-seeking behavior. Lower cognitive...
People are often diagnosed with multiple neurodivergencies and mental health conditions, but the biggest genetic analysis so far suggests many have shared biological causes
Researchers uncovered how shifting levels of a brain protein called KCC2 can reshape the way cues become linked with rewards, sometimes making habits form more quickly or more powerfully than expected. When this protein drops, dopamine...
New research shows that deep learning can use EEG signals to distinguish Alzheimer’s disease from frontotemporal dementia with high accuracy. By analyzing both the timing and frequency of brain activity, the model uncovered distinct...
Vividly imagining a positive interaction with someone can increase how much you like them — and even alter how your brain stores information about that person. During imagined encounters, participants developed stronger preferences, and...
A large study of 800 adults shows that pragmatic language skills—the ability to understand sarcasm, indirect requests, tone, and nonliteral meaning—organize into three distinct cognitive clusters. These clusters draw on social-rule...
Biologists poured cold water on Colossal Biosciences’ claim to have brought the dire wolf back from extinction, and some worry the overblown headlines will undermine conservation work
The Trump administration has targeted everything from public health to space missions for funding cuts, bringing an end to the longstanding US policy of scientific pursuits as a path towards progress and economic prosperity
We knew that GLP-1 drugs like Ozempic and Wegovy did more than just help control type 2 diabetes and aid weight loss, but the extent of that potential really came to light in 2025
Scientist and photographer Felice Frankel has zoomed in on everyday occurrences with her camera for her new book, Phenomenal Moments, which reveals the hidden science in our daily lives
Feedback has spent some time sifting through 2025's key scientific achievements to come up with a range of weird and wonderful (and less wonderful) winners for our inaugural Backsies awards
A new study proposes that autism arises when genetic vulnerability, an early environmental trigger, and prolonged activation of the cellular stress response align during critical developmental windows. This “three-hit” metabolic model...
Our gut microbiome has a huge influence on our overall health, but we haven't been clear on the specific bacteria with good versus bad effects. Now, a study of more than 34,000 people is shedding light on what a healthy gut microbiome...
Loss of function variants of SCN1B are associated with a range of developmental and epileptic encephalopathies (DEEs), including Dravet syndrome. These DEEs feature a wide range of severe neurological disabilities, including changes to...
Heterogeneity of presynaptic input and postsynaptic intrinsic excitability are two major variables that regulate neuronal firing rates and patterns. Yet, little is known about how these variables interplay to diversify the fidelity of...
Epilepsy constitutes a clinically manifest excitability disorder that is characterized by aberrant electrophysiological activity in the electroencephalogram (EEG). The correct identification of the seizure onset zone relies on the visual...
Understanding how the brain transforms peripheral sensory inputs into higher-level representations, and how these contribute to perception and behavioral performance, is a central question in sensory neuroscience. However, in human...
Hippocampal maps and ventral prefrontal cortex (vPFC) value and goal representations support foraging in continuous spaces. How might hippocampal–vPFC interactions control the balance between behavioral exploration and...
Anterior cingulate cortex (ACC) is a prefrontal area implicated in functions including cognitive control, attention, and prediction. Mouse ACC receives input from the visual system and uses visual information to direct behavior. While...
One of the core aspects of alcohol use disorder is continued use despite negative consequences. Individuals with an alcohol use disorder typically engage in behaviors which represent a failure to integrate the aversive consequences of...
Infants preferentially process familiar social signals, but the neural mechanisms underlying continuous processing of maternal speech remain unclear. Using EEG-based neural encoding models based on temporal response functions, we...
Alcohol use disorder (AUD) is a highly prevalent disorder with limited therapeutic options. The central amygdala (CeA) is a critical brain region as dysregulation within the CeA and the corticotropin-releasing factor (CRF) system are...
