Rapid Expansion of Human Settlements into Flood Zones Increases Disaster Vulnerability

ByThe Short Paper

Global evidence of rapid urban growth in flood zones since 1985

This study reveals that human settlements worldwide, from small villages to large cities, have been rapidly expanding into areas prone to flooding since 1985. This expansion is happening more quickly in high-risk flood zones compared to safer areas, particularly in East Asia. These findings highlight that, despite increasing disaster risks due to climate change, many regions continue to increase their vulnerability to flooding rather than adapting to mitigate these risks.

The Moon’s Origin Reveals Earth’s Mysterious Interior Anomalies

ByThe Short Paper

Moon-forming impactor as a source of Earth’s basal mantle anomalies Seismic images of Earth’s interior have uncovered large low-velocity provinces (LLVPs), enigmatic regions in the lower mantle. Researchers propose that these LLVPs might be remnants of Theia, a celestial body that collided with Earth, creating the Moon. Simulations suggest Theia’s mantle material integrated into Earth,…

Global Increase in Wildfire-Driven Air Pollution and Its Impact on Human Health

ByThe Short Paper

Global population exposure to landscape fire air pollution from 2000 to 2019 Wildfires, worsened by climate change, are becoming more severe and frequent. The smoke they produce, which can harm human health, hasn’t been well understood globally. Using advanced models and machine learning, scientists estimated that from 2000 to 2019, people around the world were…

Understanding the Link Between Brain Activity and Cancer Growth

ByThe Short Paper

Glioma synapses recruit mechanisms of adaptive plasticity Research reveals that the nervous system plays a significant role in cancer regulation, particularly in gliomas, a type of brain cancer. Neuronal activity influences tumor progression through specific signaling factors. In gliomas, the brain-derived neurotrophic factor (BDNF) promotes synaptic plasticity, similar to healthy brain functions. Malignant synapses in…
