Neuroscientists roll out first comprehensive atlas of brain cells

Posted: 06 Oct 2021 08:25 AM PDT

While researchers have discovered numerous cell types in the brain, this atlas of all cell types in one area -- the primary motor cortex -- is the first comprehensive list and a starting point for tracing cellular networks to understand how they control our body and mind and how they are disrupted in mental and physical disorders.

On Earth, river erosion is usually a slow-going process. But on Mars, massive floods from overflowing crater lakes had an outsized role in shaping the Martian surface, carving deep chasms and moving vast amounts of sediment, according to a new study.

Great apes' consonant and vowel-like sounds travel over distance without losing meaning

Posted: 28 Sep 2021 04:38 PM PDT

Scientists have shown that orangutan call signals believed to be closest to the precursors to human language, travel through forest over long distances without losing their meaning. This throws into question the accepted mathematical model on the evolution of human speech.

Happiness in early adulthood may protect against dementia

A new study found that the Kuroshio Current Extension is sensitive to global climate change and has the potential to warm greatly with increased carbon dioxide levels.

Children who eat more fruit and veggies have better mental health

Posted: 28 Sep 2021 04:50 AM PDT

New research finds that children who eat more fruit and veg have better mental health. The study is the first to investigate the association between fruit and vegetable intakes, breakfast and lunch choices, and mental wellbeing in UK school children. The research team studied data from almost 9,000 children in 50 schools. They found that the types of breakfast and lunch eaten by both primary and secondary school pupils were significantly associated with wellbeing.
