Simulations shows magnetic field can change 10 times faster than previously thought
(University of Leeds) A new study by the University of Leeds and University of California at San Diego reveals that changes in the direction of the Earth’s magnetic field may take place 10 times faster than previously thought.
More ecosystem engineers create stability, preventing extinctions
(Santa Fe Institute) Biological builders like beavers, elephants, and shipworms re-engineer their environments. How this affects their ecological network is the subject of new research, which finds that increasing the number of “ecosystem engineers” stabilizes the entire network against extinctions.
Raw milk may do more harm than good
Raw or unpasteurized cows’ milk from U.S. retail stores can hold a huge amount of antimicrobial-resistant genes if left at room temperature, according to a new study.
Why are plants green?
When sunlight shining on a leaf changes rapidly, plants must protect themselves from the ensuing sudden surges of solar energy. To cope with these changes, photosynthetic organisms have developed numerous tactics. Scientists have been unable, however, to identify the underlying design principle. A physicist has now constructed a model that reproduces a general feature of photosynthetic light harvesting, observed across many photosynthetic organisms.
