GENERATIONS NOT FORTHCOMING—Fewer new North Atlantic right whale calves are being born, threatening the species’ ability to survive. Scientists are seeking to understand the reasons for their low and inconsistent birth rate, which may be linked to pollution or declining food supplies. (The New England Aquarium.)
