Scientists have created a technology called Oz that stimulates individual photoreceptor cells in the human eye to create an entirely new, ultra-saturated color never seen in nature—dubbed olo. Using microdoses of laser light, Oz...
With ice and permafrost thawing fast, nations are racing to exploit the Arctic's newly accessible treasures. Yet there are plenty of reasons why this may not be a great idea – and why we should treat the region as a scientific wonder...
New research reveals that the brain stores memories of cold experiences, which can later trigger metabolic responses in anticipation of cold environments. Mice trained to associate visual cues with cold temperatures began to increase...
Micronanoplastics—tiny plastic particles from environmental sources—were found in much higher concentrations in the arteries of people with plaque-related stroke symptoms compared to those with healthy arteries. In a new study,...
The molecular mechanism behind why heart attacks can vary in severity depending on the time of day has been uncovered, potentially paving the way for innovative treatments that align with the natural circadian rhythm.
The attempted creation of dire wolves could undermine conservation efforts by making people think extinct species can be revived, says the International Union for Conservation of Nature
Our brain doesn't passively receive visual input—it actively orchestrates a symphony of neural oscillations to process the complex, dynamic scenes we see in everyday life. A new study reveals that features like brightness and contrast in...
Tinnitus is the subjective perception of a sound without corresponding external acoustic stimuli. Research highlights the influence of the sensorimotor system on tinnitus perception. Associated neuronal processes, however, are...
Perception, working memory, and long-term memory each evoke neural responses in the visual cortex. While previous neuroimaging research on the role of the visual cortex in memory has largely emphasized similarities between perception and...
The brain comprises a complex network of interacting regions. To understand the roles and mechanisms of this intricate network, it is crucial to elucidate its structural features related to cognitive functions. Recent empirical evidence...
RNA-binding proteins (RBPs) are important for posttranscriptional RNA processing, including pre-mRNA alternative splicing, mRNA stability, and translation. Several RBPs have been shown to play pivotal roles in the inner ear, whose...
Mastering the associations between letters and their corresponding speech sounds (LSS) is pivotal in the early stages of reading development, requiring an effective reorganization of brain networks. Children with poor reading skills...
Adaptive decision-making relies on flexible updating of learned associations where environmental cues come to predict valenced stimuli, such as food or threat. Cue-guided behavior depends on a network of brain systems, including...
Gadolinium-based contrast agents (GBCAs) for magnetic resonance imaging (MRI) are gadolinium chelates and can leave gadolinium in brain regions after administration, causing damage to brain tissues. However, the exact effects of...
Interval timing, the ability of animals to estimate the passage of time, is thought to involve diverse neural processes rather than a single central "clock" ( Paton and Buonomano, 2018 ). Each of the different processes engaged in...
Methylphenidate (MP) is a widely used stimulant medication for the treatment of attention-deficit hyperactivity disorder that enhances brain dopamine signaling and improves attention. However, how dopamine stimulation alters brain state...
Navigating space and forming memories based on spatial experience are crucial for survival, including storing memories in an allocentric (map-like) framework and conversion into egocentric (body-centered) action. The hippocampus and...
The motor system adapts its output in response to experienced errors to maintain effective movement in a dynamic environment. This learning is thought to utilize sensory prediction errors, the discrepancy between predicted and observed...
Our brains are in a constant state of generating predictions, implicitly extracting environmental regularities to support later cognition and behavior, a process known as statistical learning (SL). While prior work investigating the...
Human performance is endowed by neural representations of information that is relevant for behavior, some of which are also activated in a preparatory fashion to optimize later execution. Most studies to date have focused on highly...
The brain builds hierarchical phrases during language comprehension; however, the details and dynamics of the phrase-building process remain underspecified. This study directly probes whether the neural code of verb phrases involves...
Compared to males, aggression is less frequently noticed in females. Fierce maternal-aggression to thwart the attack/threat of a male conspecific/intruder is transiently expressed as she defends her pups. The odor cues emanated by the...
A new study reveals that chronic stress activates immune cells that travel to the brain, amplify inflammation, and heighten fear responses. Researchers found that psychedelics like MDMA and psilocybin disrupt this immune-brain crosstalk,...

Body appreciation differs between Middle-Eastern and Western societies, a new international study can reveal, highlighting how cultural and family influences shape body image and eating behaviors in young women. The study surveyed over...
A new study suggests that fear and the immune system are connected in previously unknown ways. Researchers found that the immune system can influence stress and fear behaviors by changing how brain cells communicate.
New multidisciplinary research shows that the brain forms memories of cold experiences and uses them to control our metabolism. The study shows that cold memories form in the brain -- and map out how they subsequently drive...
A large international study has found that middle-aged Americans report higher levels of loneliness than older adults, a pattern seen in only one other country—the Netherlands. While loneliness generally increases with age globally, the...
A new preclinical study has found that two drugs—o-Vanillin and RG-7112—can clear “zombie cells” from spinal discs, potentially treating the root cause of chronic low back pain. These senescent cells accumulate with age or injury and...
