News about Science and Technology ? Characteristics of news ? Methods or skills of using news Scientists develop cancer fighting tomato ? A purple tomato ically engineered to contain nutrients more commonly seen in dark berries helped prevent cancer in mice, British researchers said on Sunday. The finding, published in the journal Nature Biotechnology, bolsters( 长枕;支持) the idea that plants can be ically modified to make people healthier. Cancer-prone mice fed the modified fruit lived significantly longer than animals fed a standard diet with and without regular tomatoes ? Electrically stimulating the brain can help to speed up the process of learning, scientists have shown. ?电流刺激大脑能提高学习速度 The brain can change its structure in response to experience and practice 大脑可以改变它的结构对经历和实践做出回应? Applying a small current to specific parts of the brain can increase its activity , making learning easier . Researchers from the University of Oxford have studied the changing structure of the brain in stroke patients and in healthy adults. ? Prof Heidi Johansen-Berg presented their findings at the British Science Festival 英国科学日 in Bradford 布拉德福德(英格兰北部城市) . ? The team at Oxford has been conducting research into how the structure of the brain changes in adulthood 成年;***期, and in particular what changes occur after a stroke. ? They have used an approach called functional MRI 核磁共振成像( ic Resonance Imaging );机读信息( Machine Readable Information ); to monitor activity in the brain as stroke patients re-learn motor skills that were lost as a result of their illness. ? One of the major findings is that the brain is very flexible and can restructure itself, growing new connections and reassigning 再分配;再指定 tasks to different areas, when damage occurs or a specific task is practiced. ? As part of this research, they investigated the possibility of using non- invasive electric brain stimulation to improve the recovery of these motor skills; the short-term improvement in stroke patients had already been noted. ? But an unexpected result was found when the same brain stimulation was applied to healthy adults: their speed of learning was also significantly increased .?小电流的部分大脑可以提高其应用活动,使学习更容易。牛津大学的研究人员已经研究了中风患者和健康的***的大脑结构改变。他们的研究结果 Johansen-Berg 教授提出了海蒂节在英国科学在 Bradford 。牛津大学的研究小组一直进行长大***时脑变化的研
