Some of the strangest weather in the solar system doesn't happen on Earth or even in Jupiter's Great Red Spot—it happens in the interiors of ice giants like Neptune and Uranus. Specifically, scientists have long believed that, at certain pressures and temperatures, it literally rains diamonds inside these planets. For the first time, scientists have mimicked the process they believe creates this phenomenon.
More water does not necessarily produce more alfalfa seed. A five-year trial near Keith, South Australia, found that strategically delaying irrigation until plants showed early signs of leaf drop generally increased seed yield and consistently delivered the highest gross margin.
Tuberculosis bacteria released into the air from infected individuals dry out to form infectious particles that are second only to measles in contagiousness. Weill Cornell Medicine investigators have discovered specific mechanisms that enable the bacteria not only to survive drying but also to generate mutations linked to antibiotic resistance. This suggests that transmission involves more than the passive movement of bacteria between people and may be a period during which the pathogen evolves.
