Sea turtles may be eating themselves to death. In this case, though, the phrase likely doesn’t mean what you think it does.
Green sea turtles in the Caribbean may be in danger of starving to death in the near future thanks to a recent invasion of seagrass. The marine plant is spreading quickly and edging out native species helped, ironically, by the sea turtles themselves.

By the end of the century, rising CO2 levels will cut fishes’ sense of smell by nearly half, new research finds. And the impaired olfaction will threaten marine ecosystems and our food supply. That’s according to a report Monday in Nature Climate Change.
Fish need a sharp smelling sense because many species spawn offshore, forcing newly hatched fish to find their way home by following their noses. Smell also helps fish locate food, communicate with their pa ...read more
As the climate warms, seas will rise, storms will proliferate and cities will bake. But, in addition to the marquee issues global warming causes, there will likely be a host of tangential issues, many of which we may not anticipate.
A new study in Nature Climate Change looks at the psychological effects a warming climate will have on humans, focusing specifically on mental health. Though the work is somewhat preliminary, the authors pick out a broad trend of ...read more

Throughout Africa and Asia, elephants can be seen as problem causers. The behemoth mammals destroy crops and threaten farmers’ livelihoods when they trundle through fields after tasty snacks. Scarecrows, fences and noisemaking tripwires don’t deter the beasts, and tensions with humans can escalate so much that elephants are sometimes shot.
Now, scientists have discovered that the odor of angry honeybees is an effective elephant repellant. Th ...read more
Two years ago, a paper by Swedish neuroscientist Anders Eklund and colleagues caused a media storm. The paper, Cluster Failure, reported that the most widely used methods for the analysis of fMRI data are flawed and produce a high rate of false positives.
As I said at the time, Cluster Failure wasn't actually making especially new claims because Eklund et al. had been publishing quite similar results years earlier - but it wasn't until Cluster Failure that they attracted widespread attent ...read more
