NewsWarming stops tiny organisms working together
The single-celled organism Paramecium bursaria can absorb and host algae (Chlorella spp), providing benefits for both, but when scientists made the water 5°C warmer, the partnership stopped working – and the algae may even become parasitic.

NewsMicromachines are powered by tiny, active microorganisms
Researchers have created tiny, vehiclelike structures which can be maneuvered by microscopic algae. The algae are caught in baskets attached to the micromachines, which have been carefully designed to allow them enough room to continue swimming.

NewsStudy illuminates cues algae use to ‘listen’ to their environment
Plants have long been known to release chemicals to respond to stress and relay information to their neighbors. A team of scientists from Bigelow Laboratory have shown that glaucophytes, a small group of single-celled algae distantly related to plants, appear to have the same penchant for chemical communication. This suggests ...

NewsMicrorobot-packed pill shows promise for treating inflammatory bowel disease in mice
Engineers at the University of California San Diego have developed a pill that releases microscopic robots, or microrobots, into the colon to treat inflammatory bowel disease (IBD). The experimental treatment, given orally, has shown success in mice.

NewsResearchers discover genetic collaboration in harmful algae
A breakthrough study of freshwater harmful algal communities led by Dave Hambright, a Regents’ Professor of Biology at the University of Oklahoma, has discovered that complementary genes in bacteria and algae living in the same algal colonies coordinate the use and movement of nutrients within the colony. This research, funded ...
