Alzheimer's doctors also reported new discoveries about certain lifestyle factors that may accelerate or slow the dementia that often precedes Alzheimer's. Swedish psychologists studied rates of the disease in a sample of 1,449 people over a period of 21 years. They found, as previous research has suggested, that single people have up to twice the risk of developing Alzheimer's as their married counterparts. But what was unexpected was the finding that the reason for a person's singlehood impacts his or her risk. Compared with other singletons, people who were single as a result of divorce...
...first described by Japanese biologist Shinya Yamanaka, who, in 2007, showed that the introduction of four genes into an adult human skin cell could reprogram it back to an embryonic state (Yamanaka had reported the same achievement in mice the previous year). Like embryonic stem cells, these reprogrammed adult cells could be coaxed into becoming any other type of cell - from skin to nerve to muscle. But researchers questioned whether the new stem cells would behave as predictably or as safely as embryonic stem cells, or whether iPS would consistently yield usable cells. "Our work shows that the original method...
...Siemens' supervisory board is chaired by Gerhard Cromme, former CEO of German steelmaker ThyssenKrupp, and includes powerful business titans such as Josef Ackermann, the CEO of Deutsche Bank, and Michael Dieckmann, CEO of financial services giant Allianz AG. They were no doubt aware that a decision to go after previous execs Kleinfeld and particularly von Pierer - a former advisor to Chancellor Angela Merkel dubbed "Mr. Industry" by German media - would reverberate far beyond the walls of Siemens' headquarters in Munich...
There is a rather large asterisk on the new data, however, the result of an ongoing effort to more narrowly define who is actually considered homeless. This is the third annual national HUD count, and in previous years, some cities had been counting families who were living two families to an apartment, for example, or those living in RVs, as homeless. This year, they weren't. This count, say the report's authors, is the most successful to date in tallying only those who were actually in shelters or on the streets - the official HUD definition of a homeless person...
...directorship of World Health Organization, and even won the endorsement of the renowned British medical journal, The Lancet.Frenk, who started his career as an academic researcher before moving into the policy arena, said that he does not expect his position as dean to be all that different from his previous post as health minister. He emphasized that his tenure as minister was characterized by the use of scientific knowledge to guide policy. “For me, it’s all grounded in my firm belief that science and scholarship, not economic interest or short-term political gain, that...
