| Chang'e-5 samples reveal key age of moon rocks Posted: 07 Oct 2021 11:57 AM PDT A lunar probe launched by the Chinese space agency recently brought back the first fresh samples of rock and debris from the moon in more than 40 years. Now an international team of scientists has determined the age of these moon rocks at close to 1.97 billion years old. |
| Dwarf planet Vesta a window to the early solar system Posted: 06 Oct 2021 11:34 AM PDT The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent articles use data from meteorites derived from Vesta to resolve the 'missing mantle problem' and push back our knowledge of the solar system to just a couple of million years after it began to form. |
| Brain cell differences could be key to learning in humans and AI Posted: 06 Oct 2021 08:26 AM PDT Researchers have found that variability between brain cells might speed up learning and improve the performance of the brain and future AI. |
| 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. |
| Dragonflies likely migrate across the Indian Ocean Posted: 04 Oct 2021 07:41 AM PDT Can dragonflies migrate thousands of miles across the Indian Ocean, from India via the Maldives to Africa, and back again? An international research team has used models and simulations to find out if the hypothesis could be true. |
| Scientists discover 14 genes that cause obesity Posted: 01 Oct 2021 07:04 AM PDT The discovery of genes that directly cause obesity could pave the way for treatments for a condition that affects more than 40 percent of American adults. |
| Mars' surface shaped by fast and furious floods from overflowing craters Posted: 29 Sep 2021 08:28 AM PDT 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 Posted: 28 Sep 2021 09:13 AM PDT While research has shown that poor cardiovascular health can damage blood flow to the brain increasing the risk for dementia, a new study indicates that poor mental health may also take its toll on cognition. |
| Major ocean current could warm greatly Posted: 28 Sep 2021 07:22 AM PDT 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. |
