Poplar trees redirect resources in response to simulated attack
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have applied some of the same techniques used in medical imaging to track the distribution of nutrients in poplar trees in response to a simulated insect attack. The research provides new insights on a long-debated theory about how plants respond to environmental stress, and shows that radiotracer imaging can be a big he...Surgeons with video game skill appear to perform better in simulated surgery skills course
In a study involving 12 surgeons and 21 surgical residents, video game skill was correlated with laparoscopic surgery skill as assessed during a simulated surgery skills course, according to a report in the February issue of Archives of Surgery, one of the JAMA/Archives journals. James C. Rosser Jr., M.D., of Beth Israel Medical Center, New York, and colleagues asked 33 surgeons (21 reside...Down syndrome simulated in animal model after successful chromosome transplantation
The field of genetics has been undergoing a revolution with increasing importance being given to genetic mechanisms underlying common disorders and a huge amount of resources allocated to research in specific genetic disorders. // This has not only added motivation to scientists working in the field of genetics but also helped us replace the existing knowledge with those acquired new....Simulated Heart Tissue Enhances Understanding of Arrhythmias And Defibrillator Failure
Cultured Heart cells that were induced to imitate characters of the heart have led researchers to discern possible reasons for irregular heart rhythms. Studies of // this engineered tissue have unraveled that while electric shocks akin to those produced by defibrillators normally stopped errant waves, in few cases caused them to advance and proliferate. These findings have been reported...Surgeons Skilled in Playing Video Games are Good at Simulated Surgery
A report in the February issue of Archives of Surgery suggests that surgeons portraying skill in playing video games fared better// during a course on simulated surgery skills. James C. Rosser Jr., M.D., of Beth Israel Medical Center, New York, and colleagues asked 33 surgeons (21 residents and 12 attending physicians) about their video game–playing habits, then assessed their perform...
