Newly grown kidneys can sustain life in rats

... in control and experimental rats. To help resolve uncertainty about which kidney functions are critical to sustaining life, scientists cut the connections between the bladder and the new kidneys in a subset of the experimental rats. Rats with no new kidneys lived for two to three days, and rats whose new kidney...

Some plants may compensate for herbivore damage by stimulating nutrient release in the soil
