Cerebrospinal biomarker test can detect Alzheimer’s pathology earlier, study shows

Years before tau tangles show up in brain scans of patients with Alzheimer’s disease, a biomarker test developed at the University of Pittsburgh School of Medicine can detect small amounts of the clumping-prone tau protein and its misfolded pathological forms that litter the brain, cerebrospinal fluid and potentially blood, new research published today in Nature Medicine suggests.

High-tech video optimization in our brain: How the brain unblurs vision during movement

Why do our mental images stay sharp even when we are moving fast? A team of neuroscientists led by Professor Maximilian Jösch at the Institute of Science and Technology Austria (ISTA) has identified a mechanism that corrects visual distortions caused by movement in animals. The study, conducted in mice, identifies a core function that can be generalized across the vertebrate visual system, including primates such as humans. The findings are published in Nature Neuroscience.

A playful approach to life activates ‘lemonading’ to help people cope with adversity, scientists say

Scientists have found that taking a playful approach to life doesn’t mean you don’t take your situation seriously, but it can mean you cope with it better. By surveying people about their experiences during a COVID-19 lockdown, they learned that more playful people were more positive about the future and coped more actively and creatively. Life gave them lemons, and they made lemonade.

How fast is your gut? The answer to this question is important to your health
