研究人员发现影响政治参与强度的大脑回路
#科学

芝加哥西北大学的研究团队研究了有和没有脑损伤的越战老兵,这是越战头部损伤研究的一部分,这是一个长期项目,研究与战斗有关的脑损伤对神经行为的影响。在 2008 年至 2012 年间,神经科学家对这些退伍军人进行了广泛的行为问题,评估了他们的政治信仰和情感强度的各个方面——大约在他们受伤 40 到 45 年后。参与者报告了他们当前的政治行为和他们受伤前的政治行为的回忆。这项研究包括 124 名头部有穿透性创伤的美国男性退伍军人和 35 名没有持续脑损伤的战斗暴露的对照组参与者。在提问之前,科学家们已经使用损伤网络映射技术绘制了退伍军人的大脑损伤图,这是一种神经成像技术,可以识别与特定损伤相连的更广泛的大脑回路。然后,他们根据行为数据分析了特定的大脑网络是否与政治信仰有关。研究人员称,“我们没有发现与自由或保守意识形态有关的大脑网络,但我们确定了影响政治参与强度的回路,这表明,情绪等因素决定了人们如何表达已有的政治信仰,而不是决定意识形态本身。”

Telegram Gives Up On Crypto Blockchain Project

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”

What Is Bitcoin?

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
