A | Researchers from China and the UK have solved the mystery surrounding Saccorhytus coronaries – a millimeter-long spiny creature that was found in 2017 and believed to have inhabited oceans 500 million years ago. The veil of mystery over the critter persisted for years, as the scientists could not locate the creature’s anus. Turns out – they should not have even tried.,The critter was originally determined to be a member of a deuterostomes group of animals - the ancestors to the modern vertebrates (including humans). However, scientists' latest research suggests that it actually belongs to another group called ecdysozoans – the predecessors of the modern spiders and various insects. As it turned out, the whole mishap happened over the creature's anus – or rather lack thereof.,Ecdysozoans normally have an anus and hence the critter was initially ruled not to belong to them. But, upon closer discovery using x-rays, scientists saw it resembles ecdysozoans internally more than the ancestors of the vertebrates.,Like them, Saccorhytus has a large mouth and also features tiny holes around it that served as bases for spines that kept the critter anchored in one place. Those holes also served as a source of confusion as they were originally believed to be gills – another mark of the proto-vertebrates.,'Ugliest I've Ever Seen': Fisherman Shares Pic of Mysterious Creature He Found in Australia29 June, 13:17 GMT,As to Saccorhytus' absence of anus, scientists are yet to find out what happened to it. One theory suggests that there was an even earlier representative of ecdysozoans that has not been discovered, but did not have an anus.,Another theory goes that Saccorhytus did not actually need one.,"It could be that it lost it during its own evolution - perhaps it didn't need one because it could just sit in one spot with one opening for everything," Emily Carlisle, one of the researchers, said.。

B | 德国经济部长兼副总理哈贝克在和朔尔茨出席同一活动时表示,本届政府的目标是,在今年底以前,让推行电价上限成为立法。朔尔茨还在讲话中安抚德国工业企业,称政府将竭尽所能解决一切流动性问题。

C | 政府已经扩大并延长了对最受影响企业的保护范围,采取措施包括低息的KfW贷款、担保计划,以及帮助能源密集型企业。

D | 也是在周二,德国研究机构欧洲研究中心(ZEW)公布的9月ZEW经济景气指数从8月的-55.3进一步降至-61.9,创2008年10月以来新低。这一体现投资者对德国经济信心的指标比经济学家预期的-59.5还低,体现了高通胀、高取暖和能源成本对信心的打击。

E | 欧盟酝酿能源干预方案 拟对低成本电价设定180欧元上限 整体用电量减少10% 媒体指出,今年4月,德国出台了一项金融救助方案,部分用于帮助抵押品要求过高的能源企业,上述贷款担保计划并不属于该方案范畴。是德国政府新增的扶持手段。上周能源巨头挪威国家石油公司(Equinor)估算,欧洲的能源交易面临至少1.5万亿美元保证金要求,凸显能源危机下能源交易极度紧张、企业越来越无力承担日益增加的保证金要求。欧盟正在研究采取紧急行动给予相关支持。华尔街见闻本周一提到,媒体称,欧盟本周将提出的能源干预的重磅方案,内容包括设定削减电力需求的目标、对能源企业征临时的超额利润税、对通过天然气以外能源发电的企业设超额收入上限,有争议的限制进口俄罗斯天然气价格问题推迟再议。缓和能源市场因追缴保证金而流动性紧张的问题上周得到了欧盟内部的普遍支持,现在这个问题已经单独研究,不再混入方案内讨论。本周二又有媒体称,欧盟委员会在考虑将可再生能源和核能公司的发电收入上限设定在180欧元/每兆瓦时,还计划提议对石油、天然气、煤炭和精炼行业企业的超额利润征收至少33%的暂时性税费。在用电量方面,媒体称,欧盟委员会目前计划将整体用电量减少10%,同时设定在特定高峰时段将需求降低5%的强制性目标。最终数字需得到欧盟委员会的批准,然后需要各国政府批准。委员会还就能源交易抵押品事宜与银行业监管机构进行磋商,力图限制能源市场过度波动。华尔街见闻文章指出,相比此前泄露的草案金额,最新的非天然气发电收入上限有所下降,总用电削减目标则基本一致。
