But even with the annual wound care products market expected to reach $15-–$22 billion by 2024, many aspects of wound care have remained unchanged for decades. Now, teams of clinicians and engineers are working on new technologies that have the potential to transform wound care, making the process smarter, faster, and more efficient.

Now, samples collected from whaling expeditions are actually helping scientists learn more about these elusive animals and work towards their conservation.
