中国科学院古脊椎动物与古人类研究所团队在江西德安发现了志留纪盔甲鱼类新属种——隆平德安鱼(Deanaspis longpingi),属名“德安”取自化石的发现地江西九江市德安县,种名则献给故乡为德安的中国“杂交水稻之父”袁隆平院士。隆平德安鱼是一种无颌鱼类,体型非常小,头甲不足2厘米,生活在距今 4.36 亿年前的志留纪早期。该化石标本首现于 2002 年,是中国科学院南京地质古生物研究所研究员王怿在德安县志留纪地层寻找植物化石时意外发现所得。研究发现,德安鱼兼具了修水鱼类和真盔甲鱼类的镶嵌演化特征,例如纵长的中背孔、6对鳃囊以及鳃后区结构。

The STAR Market, as is implied by the name, is heavily geared toward smaller innovative tech companies, in particular those engaged in strategically important fields, such as biopharmaceuticals, 5G technology, semiconductors, and new energy. The STAR Market currently has 340 listed securities. The STAR Market is seen as important for China’s high-tech and emerging industries, providing a space for smaller companies to raise capital in China. This is especially significant for technology companies that may be viewed with suspicion on overseas stock exchanges.

Telegram Be The Next Best SPAC

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
