A new study provides the first evidence for the existence of flexible neuron modules in the brain, particularly in the prefrontal cortex. These clusters of neurons can perform the same computations across varied tasks, allowing the brain to store different types of information, such as sensory input or action plans, with remarkable adaptability. This discovery suggests that reusable circuits enable the brain to generate a wide range of behaviours efficiently.
Researchers have identified a new process, 'chronoferroptosis', where excess iron in neurons reduces their resilience to stress, increasing vulnerability to neurodegenerative diseases. This discovery highlights iron accumulation as a critical target for predicting, preventing, and treating conditions like Alzheimer's.
A recent study published in npj Aging reveals that epigenetic clocks, which estimate biological age by measuring DNA methylation, capture various aspects of aging biology, including immune system changes, metabolism, and cell communication. Researchers also developed new gene-expression-based clocks that show stronger predictive power for age-related diseases and mortality.
Scientists at IIT Mandi have identified the cellular signature of anaesthesia in plants, a discovery that challenges conventional understanding of consciousness. Their research shows plants respond to anaesthetics in a synchronised manner, reorganising cellular nuclei despite lacking a brain or nervous system, suggesting a more sentient nature than previously believed and resonating with ancient Indian philosophical thought.
A new study has identified a region in the brainstem, the structure connecting the brain to the spinal cord, that plays a crucial role in cognitive flexibility and the ability to adapt to changing conditions. Researchers found that the 'locus coeruleus' in the brainstem is central to how the brain switches between behavioural rules, impacting disorders like ADHD, depression, and OCD.
A new study reveals that neuron networks in the brain's hippocampus, the memory centre, become sparser but more structured and refined as animals mature.
A new study reveals that obesity-related changes in body fat can disrupt brain signals and immune function, potentially worsening Alzheimer's disease.
A new study suggests that newer oral weight loss drugs may do more than suppress appetite, potentially altering brain circuits that control motivation and reward, impacting how one experiences pleasure.
A new study suggests that damage to the brain's white matter can trigger features often associated with neurodegenerative diseases, such as inflammation in the grey matter.
A new study has identified two distinct subtypes of autism, one with increased communication associated with immune-related systems and another with reduced connectivity linked to synaptic pathways. The findings, published in Nature Neuroscience, pave the way for more precise and personalised autism care and support.
A new study reveals that immune cells within brain tumours may be manipulating sugar metabolism, specifically breaking down fructose, to suppress immune responses and promote tumour growth. Blocking fructose breakdown in these cells could improve immunotherapy outcomes for glioblastoma patients.

The world looks very different under a microscope... Don't believe us? Here's a look at the Nikon Small World Photomicrography Competition, which celebrates images taken using microscopes and has announced the winning photos for its 2020 contest. A beautiful image of the dorsal side of a zebrafish won the first prize. The image was taken by Daniel Castranova and assisted by Bakary Samasa while they were working in the lab of Dr. Brant Weinstein at the National Institutes of Health. Not only was it an amazing microscopic photo, but the image was significant because it helped Castranova's team in a groundbreaking study about the anatomy of zebrafish. Here are our choices of the 15 of the best images from the contest.
Chips based on ARM processor technology would be linked together to simulate the highly-complex workings of the brain, whose functionality derives from networks of billions of interacting, highly-connected neurons.
