MIT astronomers have found a way to spot the smallest, “decameter,” asteroids within the main asteroid belt. They used their approach to detect more than 100 new asteroids, ranging from the size of a bus to several stadiums wide, which are the smallest asteroids within the main belt detected to date. 

Eric Stach of the University of Pennsylvania's School of Engineering and Applied Science and colleagues used neural networks to better identify the characteristics of catalysts that drive the creation of liquid fuels from sunlight.

Nearly 21% of households in states heavily affected by hurricanes Helene and Milton report sometimes or often not having enough to eat within the first seven days of the storms’ impact, according to the November 2024 Consumer Food Insights Report (CFI).

Tokyo, Japan – Researchers from Tokyo Metropolitan University showed that agricultural land preserved around river confluences can help mitigate floods. They make a case for Eco-DRR, an approach that uses existing environmental resources to improve resilience against flooding. Statistical analysis showed that municipalities with agricultural land in areas with high water storage potential suffered fewer floods, with stronger correlation when agricultural land was situated near river confluences. The team hope their findings inform effective land usage.
