Crows are intelligent and have been able to survive in diverse and difficult situations. Past researchers have proved that crows effectively use many tools. However, a technologically advanced species of crows, the New Caledonian crows, have been captured on camera making tools which they used for foraging.
Researchers at University of California, Los Angeles have developed high strength metal using magnesium and ceramic silicon carbide nanoparticles. The research team claimed that the metal has much better stiffness-to-weight ratio compared to strong materials used in the past. The metal created by UCLA team can withstand high heat without facing any changes in its properties.
The massive mudslide witnessed in March 2014 in Oso, Washington led to massive loss and left many people with bad memories. Geologists have worked in the region and estimated that similar landslides might have happened in the region in the past as well. However, the estimate was timing on those landslides was not easy.
