( Research identifies characteristics of cities that would support young people's mental health
Mar 25th 2024, 17:24

As cities around the world continue to draw young people for work, education, and social opportunities, a new study identifies characteristics that would support young urban dwellers' mental health. The findings, based on survey responses from a global panel that included adolescents and young adults, provide a set of priorities that city planners can adopt to build urban environments that are safe, equitable, and inclusive.

( More exposure to artificial, bright, outdoor night-time light linked to higher stroke risk
Mar 25th 2024, 17:24

Air pollution and night-time outdoor light each were associated with harmful effects on brain health, finds new study.

( Human brains are getting larger: That may be good news for dementia risk
Mar 25th 2024, 17:24

A new study has found human brains are getting bigger. The increased size may lead to a brain reserve, potentially reducing the risk of dementia.

( 2 in 3 parents say their adolescent or teen worries about how sick days may impact grades
Mar 25th 2024, 17:24

Many parents recognize increasing mental health concerns among children, reflected by the 1 in 5 who say they're open to allowing a child to take a mental health day.

( Teacher effectiveness for students with and without disabilities
Mar 25th 2024, 11:42

Research has often focused on how teachers and educators can best instruct and accommodate students with disabilities. However, are the methods used to teach students with disabilities effective and inclusive for all students?

( Greener streets linked to better sleep
Mar 25th 2024, 11:41

Living on a greener street or having views of blue spaces from your home may help you sleep for longer. New research across 18 countries found that living on greener streets -- those with visible grass, trees, and vegetation -- is linked to better sleep.

( The aging brain: Protein mapping furnishes new insights
Mar 22nd 2024, 14:55

For the neurons in the brain to work smoothly and be able to process information, the central nervous system needs a strictly regulated environment. This is maintained by the blood-brain barrier, whereby specialized brain endothelial cells lining the inner walls of blood vessels regulate the exchange of molecules between the circulatory and nervous systems. Earlier studies have shown that various functions that are dependent on these cells, such as the integrity of the blood-brain barrier or the regulation of blood supply to the brain, decline over the course of a person's life. This dysregulation leads to a dysfunction of the brain vasculature and is therefore a major contributor to medical conditions such as strokes and dementia.

( Early intervention after the first seizure may prevent long-term epilepsy and associated cognitive deficits
Mar 22nd 2024, 14:54

Only a very small percentage of neurons show changes after an epileptic seizure in mice, but these alterations can be permanent and trigger future seizures. An experimental treatment may prevent these long-term changes.

( Novel genetic variants associated with Alzheimer's disease
Mar 21st 2024, 15:54

A new study has identified 17 genetic variants that may influence Alzheimer's disease risk, putting researchers one step closer to uncovering biological pathways to target for future treatment and prevention.

( High-resolution brain created with 3D printer
Mar 21st 2024, 15:54

A 3D-printed 'brain phantom' has been developed, which is modeled on the structure of brain fibers and can be imaged using a special variant of magnetic resonance imaging (dMRI). The scientific team has now shown in a study, these brain models can be used to advance research into neurodegenerative diseases such as Alzheimer's, Parkinson's and multiple sclerosis.

( The power of neighbors: Neighboring synapses shape learning and memory
Mar 21st 2024, 15:54

A researcher has developed a new model that provides a holistic view on how our brain manages to learn quickly and forms stable, long-lasting memories. Their study sheds light on the crucial role of interactions among neighboring contact sites of nerve cells for brain plasticity -- the brain's ability to adapt to new experiences.

( Immune cells identified as key players in brain health
Mar 21st 2024, 15:54

Using novel genetic and genomic tools, researchers have shed light on the role of immune cells called macrophages in lipid-rich tissues like the brain, advancing our understanding of Alzheimer's and other diseases. The study represents a step forward in understanding immune cell regulation and its impact on disease progression.

( New archive of ancient human brains challenges misconceptions of soft tissue preservation
Mar 20th 2024, 12:24

A new study has challenged previously held views that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, which highlighted that nervous tissues actually persist in much greater abundances than traditionally thought, assisted by conditions that prevent decay.

( Is the secret to anxiety in young women hidden in our brain chemistry?
Mar 19th 2024, 12:30

The development of anxiety in girls and young women may stem from an imbalance between two crucial brain chemicals, gamma-aminobutyric acid (GABA) and glutamate, according to a new study. This discovery offers promising insights into potential treatment avenues for girls and women dealing with anxiety.

( Brain-inspired wireless system to gather data from salt-sized sensors
Mar 19th 2024, 12:30

In a new study, researchers describe a novel approach for a wireless communication network that can efficiently transmit, receive and decode data from thousands of microelectronic chips that are each no larger than a grain of salt.

( Artificial nanofluidic synapses can store computational memory
Mar 19th 2024, 12:30

In a step toward nanofluidic-based neuromorphic -- or brain-inspired -- computing, engineers have succeeded in executing a logic operation by connecting two chips that use ions, rather than electrons, to process data.
