New genetic data overturn long-held theory of limb development
...at this toolkit exists in some primitive form in a living
primitive bony fish, the paddlefish. "We found that the genetic capability seen in tetrapods to build limbs is present in even more primitive fish," said lead author Marcus Davis, PhD, a postdoctoral fellow in Neil Shubins lab at the University of Ch...

animal, via contaminated food or open wounds, leading to infant botulism or wound botulism, both of which are serious human infections. The host can be quickly overpowered and, in some cases, killed by the toxin, and C. botulinum has a new food sourc...
In new statistical approach, data decide model

organisms. "Using mathematical concepts from inverse scattering and modern statistics, we let the data 'speak,' and automatically generate an appropriate model," said Ping Ma, a professor of statistics at the U. of I. and lead author of a paper descr...
Plants that produce more vitamin C may result from UCLA-Dartmouth discovery
...that waste product probably killed off most of all living
species at that time," Clarke said. "The only organisms that survived developed defenses against it, and one of the best defenses is vitamin C. Plants learned how to make vitamin C to protect themselves." Prior to the new research, vitamin C may ha...

in different habitats can reveal the similarity of those ecoregions now and in the past. The study, one of the first of its kind, identified 28 key regions for bushbucks. By understanding the genetic similarity of populations inhabiting different...

Cannibalism of the young allows individual fish to specialize

in the same lakes but utilizing different food resources in order to survive. The phenomenon is called resource polymorphism and has been observed and documented as early as in the 18th century, but has continued to receive a lot of scientific intere...
