Like ancient mariners, ancestors of Prochlorococcus microbes rode out to sea on exoskeleton particles
In a new study they propose that ancestors of Prochlorococcus acquired an ability to latch onto chitin — the degraded particles of ancient exoskeletons. The microbes hitched a ride on passing flakes, using the particles as rafts to venture further out to sea. These chitin rafts may have also provided essential nutrients, fueling and sustaining the microbes along their journey.
Blue whale foraging and reproduction are related to environmental conditions, study shows
A new study of New Zealand blue whales’ vocalizations indicates the whales are present year-round in the South Taranaki Bight and their behavior is influenced by environmental conditions in the region.
Ancient chimaeras were suction feeders, not shell crushers, new research shows
A rare three-dimensional fossil of an ancient chimaera has revealed new clues about the diversity of these creatures in the Carboniferous period, some 300 million years ago.
Early humans: Annual cycles in tooth enamel provide insights into life histories
If you take a magnifying glass and a torch and look at your teeth very carefully in the mirror, in places you can spot a pattern of fine, parallel lines running across your teeth. These correspond to the striae of Retzius that mark the growth of our tooth enamel.
Think fast! Clever monkeys plan their food trips to avoid stronger rivals
Vervet monkeys are quick and clever planners of the best route to follow on foraging trips, shows a new study.
