Life extension science, also known as anti-aging medicine, indefinite life extension, experimental gerontology, and biomedical gerontology, is the study of slowing down or reversing the processes of aging to extend both the maximum and average lifespan. The ability to achieve this; however, does not currently exist.
Some researchers in this area, and "life extensionists", "immortalists" or "longevists" (those who wish to achieve longer lives themselves), believe that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such as with artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans (agerasia) through complete rejuvenation to a healthy youthful condition. The ethical ramifications, if life extension becomes a possibility, are debated by bioethicists.
The sale of purported anti-aging products such as supplements and hormone replacement is a lucrative global industry, with the US market generating about $50 billion of revenue a year. The use of such products has not been proven to effective or safe.
確証バイアス（かくしょうバイアス、英: Confirmation bias）とは、認知心理学や社会心理学における用語で、仮説や信念を検証する際にそれを支持する情報ばかりを集め、反証する情報を無視または集めようとしない傾向のこと。 Confirmation bias, also called confirmatory bias or myside bias,[Note 1] is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses, while giving disproportionately less consideration to alternative possibilities. It is a type of cognitive bias and a systematic error of inductive reasoning. People display this bias when they gather or remember information selectively, or when they interpret it in a biased way. The effect is stronger for emotionally charged issues and for deeply entrenched beliefs. People also tend to interpret ambiguous evidence as supporting their existing position. Biased search, interpretation and memory have been invoked to explain attitude polarization (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence), belief perseverance (when beliefs persist after the evidence for them is shown to be false), the irrational primacy effect (a greater reliance on information encountered early in a series) and illusory correlation (when people falsely perceive an association between two events or situations).
US Spy Agency Staggers, But Still Standing After Latest WikiLeaks Dump 今日のＤＭＭ英会話のタイトル
The jury is still out about whether the latest CIA document release will cause harm. But what they could potentially be holding back may be more alarming.
Ｏn this week’s episode of The E.R., David Rothkopf, Susan Hennessey, and David Sanger discuss the latest on all things intel and cyber. WikiLeaks just dumped a whole trove of CIA documents outlining methods and techniques used by the agency to hack into smartphones, cameras, computers, and other devices. Is this latest document dump from the infamous whistleblower organization cause for concern? Or are most of the details from these documents old news?
And speaking of hacking, the panel then shifts focus to President Trump’s allegations that Obama tapped phones in the Trump Towers prior to the election. With no substantive evidence and no understanding of executive power (not to mention the fact that the president can’t just request to listen in on certain people), why would Trump make such an impulsive accusation?
