"Samples taken from the asteroid Bennu by NASA's OSIRIS-REx spacecraft suggest the parent body it originated from is likely to have contained salty, subsurface water. This finding provides insights into the chemistry of the early Solar System, and suggests that brines might have been an important place where pre-biotic molecules were formed. 08:01 How gene expression doesn't always reflect a cell's function Cells are often grouped into categories according to the RNA molecules they produce."
"12:01 The disproportionate mortality risks of extreme rainfall An assessment of death rates in India's coastal megacity of Mumbai revealed that the impact of extreme rainfall events will be highest for women, young children and residents of informal settlements. This situation is likely to become more pronounced as a result of climate change. 14:46 An AI-designed underwater glue Inspired by animals like barnacles and aided by machine learning, researchers have developed a super-sticky compound that works as an underwater adhesive."
Samples from asteroid Bennu returned by NASA's OSIRIS-REx indicate the asteroid's parent body likely contained salty subsurface water, implying ancient brines. Those brines provide insights into early Solar System chemistry and could have hosted pre-biotic molecule formation. Zebrafish brain analysis shows that cells with similar RNA profiles can have diverse functions, complicating cell-type classification based purely on gene expression. An assessment in Mumbai finds extreme rainfall disproportionately increases mortality among women, young children, and informal-settlement residents, a pattern likely worsened by climate change. Inspired by barnacles and designed with machine learning, researchers produced a super-sticky underwater adhesive that adheres under wave action.
