How Antioxidants Protect Astronauts’ Brains from Space Radiation

A new study has found that galactic cosmic radiation (GCR) can cause long-lasting learning deficits in female rodents, adding to the known risks of space travel on cognitive health. The study also revealed that feeding the mice an antioxidant and anti-inflammatory compound called CDDO-EA reduced the cognitive impact of GCR exposure. These findings have significant implications not only for space exploration but also for understanding the long-term effects of radiation on the brain.

Cognitive Impacts of COVID Equivalent to 20 Years of Brain Aging

A new study reveals that 12-18 months after hospitalization for COVID-19, patients show significant cognitive decline comparable to 20 years of aging. MRI scans and blood tests also show brain injury markers and reduced brain volume in these patients. The findings suggest that COVID-19 has lasting effects on brain health, even in those without neurological complications.

Varied Cognitive Training Boosts Learning and Memory

New research shows that varied cognitive training, rather than repetitive tasks, helps older adults improve working memory. Participants who engaged in multiple types of memory exercises saw the greatest improvement compared to those who repeated the same task.

Neurodevelopmental Disruptions Behind Schizophrenia Cognitive Deficits

A recent review of genetic and population studies reveals that premorbid cognitive deficits in schizophrenia, such as lower IQ, are largely due to neurodevelopmental disruptions rather than inherited genetic variants that directly increase schizophrenia risk. The findings suggest that non-familial factors, including rare genetic mutations and environmental influences, play a significant role in both cognitive impairments and schizophrenia risk.

COVID’s Inflammation Linked to Long-Term Brain Effects

New research uncovers how COVID-19 may cause neuroinflammation, leading to persistent neurological symptoms even after recovery. The study found elevated levels of pro-inflammatory cytokines and significant changes in cerebrospinal fluid among hospitalized patients, highlighting the brain's vulnerability to the virus.

Non-Cognitive Skills Are as Vital as Intelligence

A new study reveals that non-cognitive skills like motivation and self-regulation are as crucial as intelligence in determining academic success. These skills, influenced by both genetics and environment, grow increasingly important throughout a child's education.

How Logical Thinking and Empathy Define Wisdom

A new study reveals that people across 12 countries and five continents perceive wisdom through two key dimensions: reflective orientation and socio-emotional awareness. Reflective orientation includes logical thinking and emotion control, while socio-emotional awareness focuses on empathy and social context. These dimensions consistently influence how individuals judge wisdom in leaders, scientists, and others. The findings highlight the universal principles that shape perceptions of wisdom and their implications for leadership and education.

Blocking a Brain Pathway Reverses Memory Loss in Alzheimer’s

Blocking the kynurenine pathway, a regulator of brain metabolism, can restore cognitive function in lab mice with Alzheimer’s disease. The pathway is overactivated in Alzheimer’s, disrupting glucose metabolism and starving neurons of energy. By inhibiting this pathway, researchers improved memory and brain plasticity in mice, offering hope for new treatments in humans. IDO1 inhibitors, currently in cancer trials, could be repurposed for Alzheimer’s treatment.

Child Signals: Vocal Cues Shape Adult Perceptions

Human children depend on caregivers for extended periods, employing complex vocal and cognitive cues to elicit adult attention and care. Recent research shows that adults prioritize vocal cues when assessing children's emotions and perceived helplessness, while cognitive cues weigh more in evaluating intelligence.

GLP-1 Drug Slows Alzheimer’s Cognitive Decline

A recent study suggests that a GLP-1 drug, liraglutide, may protect the brains of people with mild Alzheimer’s disease, slowing cognitive decline by 18% over one year. This effect is likely due to the drug’s ability to reduce brain inflammation, improve insulin resistance, and lower the impact of Alzheimer’s biomarkers.
