Breeding Better Buildings
C ivil engineers are often very conservative in how they pursue their profession-and for good reason: If their designs don't work, things can fall down and kill people (as the recent bridge collapse in Minnesota so clearly demonstrates). Following novel approaches increases the probability of making such disastrous mistakes. It can therefore be prudent to build on designs that are known to func...
متن کاملPlant Breeding: Surprisingly, Less Sex Is Better
Introduction of apomixis, asexual reproduction through seeds, into crop species has the potential to dramatically transform plant breeding. A new study demonstrates that traits can be stably transferred between generations in newly produced apomictic lines, and heralds a breeding revolution needed to increase food production for the growing planet.
متن کاملBreeding sows better suited to group housing
Housing of pregnant sows is currently being revolutionised around the world. Group housing enhances opportunities for improved sow health and welfare through enabling exercise and social interactions. However, because it enables social interactions, group housing can also be detrimental to welfare and production, particularly if sow aggression occurs. Detrimental effects of adverse interactions...
متن کاملFor better or worse: reduced adult lifespan following early-life stress is transmitted to breeding partners.
Stressful conditions early in life can give rise to exaggerated stress responses, which, while beneficial in the short term, chronically increase lifetime exposure to stress hormones and elevate disease risk later in life. Using zebra finches Taeniopygia guttata, we show here that individuals whose glucocorticoid stress hormones were experimentally increased for only a brief period in early pos...
متن کاملBreeding for better welfare: genetic goals for broiler chickens and their parents
Genetics is key to the improvement of welfare in broiler chickens at both juvenile and adult (breeder) stages but progress is hampered currently by the seemingly conflicting demands of welfare, commercial production, food security and calls for increasing intensification to curb climate change. Animal welfare is therefore most likely to be improved on a commercial scale by future breeding progr...
