are fed on corn—not to mention all the energy spent fertilizing, maintaining, and harvesting a crop like corn. Conversely, deriving ethanol from plant materials such as the corn stalks and wood chips is challenging because the plants?cellulose is a v...
The penalty of having a sister -- why sibling sex matters for male saiga antelopes

for example, it is well known that calves from mixed litters are less fit. Female heifers from mixed litters are generally infertile. But unlike dairy cows, in cases of saiga mixed-sex twins, the male foetus appears to be worse off, not the female. ...

Wisconsin scientists find a way to make human collagen in the lab
...ine collagen because the material now gleaned from cows
can prompt an unwanted immune response in patients and it can harbor animal pathogens that might infect humans. The Wisconsin team discovered a way to make the long, slender collagen molecules, in essence, by having the protein assemble itself. What...
Testes to incubate stem cells
