AI-assisted ultrasound could enable non-sonographer operators to deliver expert-level gestational age assessments

A study by Google Research and Google for Health demonstrates that AI can be used to assess gestational age in ultrasound scans, enabling non-sonographer operators with low-cost probes to deliver expert-level assessments. This could significantly expand life-saving maternal care globally, especially in low-resource settings where access to diagnostic medical imaging is limited.

New NASA Study Maps Human Influence on Earth's Water Cycle

A new NASA study reveals how human activities, such as irrigation and land-use changes, are affecting terrestrial water storage. The study, based on satellite measurements, identifies 40 regions where these activities have a stronger impact on water storage trends than climate variability. The findings highlight the importance of understanding human influence on Earth's water cycle.

AI model decodes the language cells use to communicate

Scientists have developed an AI model that can decode the language cells use to communicate, which could help understand how tissues develop and how diseases occur. The model analyzes signaling pathways that translate external signals into specific changes in gene activity in cells, offering a powerful way to study tissue development and disease.

What are Kelvin waves? They're large, slow-moving ocean waves that don't break onshore.

Kelvin waves are large-scale, slow-moving ocean waves that don't break onshore like typical waves. They're difficult to see with the naked eye. In this graphic, satellite radar altimetry measurements reveal the sea surface signature of Kelvin waves, showing elevated sea surface heights in yellow and red/orange colors.
