The work provides a comparative evaluation of the characteristics of various large DNA fragment assembly strategies used in different host cells, focusing on their limitations, time requirements, and the respective advantages and disadvantages of each approach. 

Earth’s rocky layers are mysteriously low in nitrogen compared with carbon and argon. A scientific team explored our planet’s molten youth using advanced quantum mechanical simulations, revealing nitrogen’s secret: under extreme pressure, it chose to hide in the iron core 100 times more than the mantle. This solved why Earth’s volatile ratios involving nitrogen look odd. The findings suggest the necessary ingredients for developing a habitable world may have been settled in the early Earth.

O‘ahu’s sandy beaches are at risk. New research from the Coastal Research Collaborative (CRC) at the University of Hawai‘i (UH) at Mānoa determined that 81% of O‘ahu’s coastline could experience erosion by 2100, with 40% of this loss happening by 2030. Importantly, these forecasts of shoreline erosion are more extreme than previous studies indicated for Oʻahu.
