Sense of Smell Relies on Predictive Coding More Than Vision

Our sense of smell operates on predictive coding more so than vision, challenging previous notions of smell as a primitive sense. Through a series of experiments, including behavioral studies and fMRI brain imaging, the study highlights smell's sophistication in reacting to unexpected stimuli by engaging not just the olfactory but also the visual brain regions.

Sleeplessness Makes You Feel Up To Ten Years Older

Researchers unveiled a link between sleep quality and subjective age, demonstrating that insufficient sleep can make individuals feel significantly older. Through two studies involving over 600 participants, they found that each night of inadequate sleep contributed to feeling 0.23 years older, with sleep restriction causing participants to feel on average 4.4 years older.

Sleepiness Can Have a Negative Impact on Your Social Life

Higher levels of sleepiness were associated with a reduction in both social activities and the amount of time people engage in social events. Social activities in the afternoons were linked to increased sleepiness following the engagement and longer sleep duration at night. Higher levels of social interaction at night were linked to reduced immediate sleepiness and shorter overall sleep duration.

Coat of proteins makes viruses more infectious and links them to Alzheimer’s disease

Herpes simplex virus type 1 (HSV-1) and respiratory syncytial virus (RSV) interact with biological fluids, creating a coat of proteins around the viral surface. This results in the viruses becoming more infectious and can contribute to the formation of amyloid plaques. In animal models, researchers found these viruses can bind to amyloid proteins, which aggregate into plaques that contribute to Alzheimer's disease. HSV-1 is able to accelerate the transformation of soluble amyloid proteins into amyloid plaques.

How Toxoplasmosis Exploits Immune Cells to Reach the Brain

Stockholm University researchers have discovered how a common parasite found in cat feces moves through the body and enters the brain. Toxoplasma gondii is able to take control of immune cells and use them to move through the body, eventually reaching the brain.
