Suppose scientists could erase certain memories by tinkering with a single substance in the brain. Could make you forget a chronic fear, a traumatic loss, even a bad habit.

Researchers in Brooklyn have recently accomplished comparable feats, with a single dose of an experimental drug delivered to areas of the brain critical for holding specific types of memory, like emotional associations, spatial knowledge or motor skills.

The drug blocks the activity of a substance that the brain apparently needs to retain much of its learned information.

Shenyang, literally meaning “the city to the north of Shen River” and capital of the Liaoning province, is touting itself as China’s “next tourist destination.” But whether you are visiting the ancient pagodas of Old City or the official “High-tech Industrial Development Zone” the tourist brochures won’t mention the city’s male and female sex workers who mostly come from poor rural communities in search of talked-up urban opportunities. In partnership with the Ai Zhi Yuan Zhu Center for Health and Education documentary filmmaker Wei Zhang will train male and female sex workers who use the AZYZ center how to maintain a blog and upload short video documentaries to share their experiences, opinions, and troubles in order to promote more understanding of the region’s sex worker population.

Thirteen years ago in Beijing, you spoke eloquently about the duty of all governments to respect the fundamental human rights of women and men. Respect for human rights, you said, means “not taking citizens away from their loved ones and jailing them, mistreating them, or denying them their freedom or dignity because of the peaceful expression of their ideas and opinions.” In recent years, however, human rights concerns have been pushed progressively further to the margins of the U.S.-China relationship. The Chinese government’s growing financial, diplomatic, and military strength, coupled with its hostility to reforms that challenge the Chinese Communist Party’s grip on power, make China a difficult country in which to effect change. But the advancement of human rights in, and with, China is arguably more central to U.S. interests than ever before. Press censorship in China makes it possible for toxic food and public health crises to spread globally. Suppression of dissent removes internal checks against environmental damage that has global impact. Abuses of low-wage labor implicate international firms operating inside China and compromise goods that come into the United States. The government’s control of mass media and the internet allow it to stoke nationalist anger against the United States in moments of crisis. The export from China of internet-censoring technologies and its provision of unconditional aid to repressive regimes increases the United States' burdens in fighting censorship and human rights crises worldwide. As much as the Chinese government appears to resist outside pressure to improve its record, experience suggests that it does respond to such pressure.

中科院《国家健康报告》从裁减军备、消除贫困、发展援助、资源节约和保护环境等方面，对全球45个样本国家的国家责任进行评估，结果中国、墨西哥、巴西、泰国、菲律宾居前五名，排最后五位的分别是英国、意大利、以色列、新加坡、美国。

在全球“国家责任指数”排行榜中，除北欧国家外，发达国家的国家责任排名普遍靠后。中科院国家健康课题组指出，发达国家不负责任导致联合国“千年发展目标”难以实现，因此，各国尤其是发达国家，应切实履行相应国家责任，更好地加强合作，推动并保证“千年发展目标”得以如期实现。

中国科学院国家健康研究课题组还以国家健康指数（NHI）为序，对全球45个样本国家的国家健康状况进行分类排行，中国居第13位，属“健康达标型”国家。45个样本国家按NHI排序，芬兰以0.655高居榜首，中国以0.576名列第13，尼日利亚以0.387垫底。

With that in mind, what Taihu’s Algae was to environmentalism, and the 5.12 earthquake was to philanthropy, this latest scandal will be the next turning point in China’s civil society.

Chinese parents hold little else more important than their child’s health, and as we saw in Sichuan after the loss of thousands of school children, parents are not afraid to be vocal and active.  Where this will be an opportunity to take civil society, and public participation, to the next level is that the public at large (children or not) will relate to those who have been affected.

中国政府可能多少也认同缅甸不愿让西方救援人士在本土工作的做法。Wang Fei-Ling谈到，在此前历次灾害中，中国政府从未允许西方机构在境内独立运作，唯一的例外是2003年非典型肺炎(SARS)爆发期间对世界卫生组织(World Health Organization)的调查网开了一面。

最近一项报告指出，如果你在40多岁时有一个大肚腩，那么在晚年患上痴呆症的几率大概要增加两倍。不过，这也许只是肥胖所带来恶果的冰山一角。内脏器官周围脂肪堆积而成的大肚腩还跟糖尿病、高血压、中风、心脏病、胆囊疾病、睡眠窒息和多种癌症有关。

三个研究小组各自独立地发现了一组基因变异，这种变异会增加患肺癌的风险，也许还会使吸烟者对尼古丁更加上瘾。他们的论文发表在《自然》(Nature)和《基因研究》(Genome Research)杂志上。

这三个小组分别来自冰岛基因公司deCode、德克萨斯大学(University of Texas)和里昂的国际癌症研究所(International Agency for Research on Cancer)，它们对增加的风险达成了一致意见。从父亲或母亲那里遗传了这种基因变异的人，患肺癌的机率比没有变异的人高出30%。那些从父母双亲那里都遗传了基因变异的人，患肺癌的可能性会增加80%。

It was the latest in a series of rare but increasingly ambitious organized movements in Chinese cities aimed at derailing government-backed industrial projects that the protesters said could damage the environment and people’s health. The protest Sunday, like its predecessors, was organized through Web sites, blogs and cellphone text messages, showing how some Chinese are using digital technology, despite government attempts to control the Internet, to spur on the kind of civic movements that officials strongly discourage.

不一会儿，其她妇女们加入诅咒行列，让整个地铁车厢成了一个反对总统及其家人、密友的抗议集会，不满这些人任由穷病杀害埃及民众－不论老少。

中新社宁波十二月二十九日电(记者曾利明)有沉默杀手之称的丙型肝炎在中国内地发病逐年上升，截止今年十一月，全国新发病近十万例。由于它尚未为公众广泛认知，初始症状不明显，往往被患者忽略，得不及时诊治，导致发展成为肝硬化和肝癌。 为此，中国肝炎防治专家今天呼吁医生和公众提高对丙肝的正确认知，及早发现、诊断、治疗以期控制这种严重的慢性传染病。
