| 'Speed gene' in modern racehorses originated from British mare 300 years ago, scientists claim Posted: 24 Jan 2012 11:01 AM PST Scientists have traced the origin of the 'speed gene' in Thoroughbred racehorses back to a single British mare that lived in the United Kingdom around 300 years ago.  |
| Genetically modified food safe, animal study suggests Posted: 24 Jan 2012 11:01 AM PST A three year feeding study has shown no adverse health effects in pigs fed genetically modified (GM) maize. The maize, which is a Bt-maize bred for its insect resistant properties, was sourced from Spain.  |
| Improving crops from the roots up Posted: 24 Jan 2012 11:01 AM PST Scientists have taken us a step closer to breeding hardier crops that can better adapt to different environmental conditions and fight off attack from parasites.  |
| How Fic proteins regulate their potentially lethal enzyme activity Posted: 23 Jan 2012 06:44 AM PST Researchers have been able to elucidate a regulatory mechanism conserved throughout evolution which forces the largely unexplored enzyme family of Fic proteins into an inactive resting state. The researchers could demonstrate that through the alteration of one single amino acid this inhibition of enzyme activity can be relieved. Their findings will enable to investigate the physiological role of the potentially lethal function of Fic proteins in bacteria and higher organisms in the future.  |
