中风发生时，一切都是以秒来计算的。延误治疗可能导致大脑重大损伤。伦敦大学医学院的一位博士Alistair McEwan已经获得行为医学研究所(Action Medical Research)的同意，为急救人员开发一种无线诊断系统来减少时间延误。感谢抗血栓药物，一些病人在病情发作的三个小时之内可以完全恢复。但出血也会导致中风。医生在治疗之前需要确定发病原因，因为不适当的服用抗血栓药物会加重损害。...[详细]
卡巴斯基的安全研究人员称其发现了如何攻击Intel微处理器的远程攻击代码，据传，这一代码可以通过TCP/IP包和JavaScript代码到达用户系统。 目前受影响的系统包括Windows XP，Vista，Windows Server 2003，Windows Server 2008，Linux甚至是BSD和Mac。但所幸大多数错误可以由Intel和BIOS厂商联合进行修复。 卡...[详细]
