Summary: Standard dietary recommendations may not suit everyone equally—especially people with genetic variants that raise Alzheimer’s risk. In a 15-year Swedish cohort study of more than 2,100 older adults, researchers found that carriers of the APOE 3/4 and 4/4 genotypes—variants linked to substantially higher dementia risk—showed slower cognitive decline and a lower incidence of dementia … Read more

Summary: A new study presented at ESC Acute CardioVascular Care 2026 indicates that measuring blood levels of neurofilament light chain (NfL) 48 hours after out-of-hospital cardiac arrest can accurately predict long-term cognitive outcomes. Researchers compared NfL with the commonly used biomarker neuron-specific enolase (NSE) and found that NfL showed markedly better diagnostic performance for forecasting … Read more

Summary: New research identifies a persistent leak in the blood-brain barrier (BBB) as a likely mechanism connecting repetitive head injuries to long-term cognitive decline in some retired athletes. By combining advanced MRI scans of living former rugby players and boxers with post-mortem tissue analyses from individuals diagnosed with Chronic Traumatic Encephalopathy (CTE), the researchers found … Read more

Summary: New research from the Stevens Institute of Technology argues that AI failures at work are rarely caused by a lack of intelligence. Instead, they stem from a mismatch in how humans and machines interpret tasks — what the study calls a lack of “cognitive alignment.” Treating AI as a plug-and-play replacement creates friction because … Read more

Summary: New research shows that ants’ ability to tell nestmates from outsiders is not a fixed genetic program but a flexible, learned behavior. Working with clonal raider ants, researchers found that ants have an intrinsic “sense of self” linked to their genotype, yet they can update their social template through repeated exposure to foreign colony … Read more

Summary: A Columbia University study finds a clear association between worsening financial well-being and faster cognitive decline in middle-aged and older adults. Over a decade-long follow-up of more than 7,600 participants, researchers report that significant financial deterioration corresponds to memory decline equivalent to roughly an extra five months of aging per year. The study suggests … Read more

Summary: A large-scale survey of more than 9,400 dogs finds that several popular “designer” Poodle crosses—Cockapoos, Cavapoos and Labradoodles—often show higher rates of undesirable behaviors than one or both of their purebred progenitors. Using the Canine Behavioural Assessment and Research Questionnaire (C-BARQ), researchers challenge the common assumption that these crosses are automatically calmer, easier to … Read more

Summary: The shift from prenatal brain growth to postnatal circuit refinement depends on the enzyme glutamine synthetase (GS) moving from neural stem cells into astrocytes. While embryonic neurogenesis proceeds largely normally without GS, the enzyme becomes critical after birth for the structural and functional maturation of the cerebral cortex. New research shows GS acts as … Read more

Summary: As medical care allows people with Type 1 diabetes to live longer, a large new study of more than 280,000 adults finds a substantially higher association between Type 1 diabetes and dementia than previously recognized. The analysis suggests the dementia risk linked to Type 1 may exceed that seen with Type 2 diabetes, highlighting … Read more

Summary: Do we react to a loaded gun the same way we react to a venomous snake? New research indicates that while both modern and ancestral dangers produce physiological responses, threats with deep evolutionary roots provoke stronger and more distinct bodily reactions. By recording electrodermal activity (skin resistance, a proxy for sweating) alongside participants’ self-reported … Read more
