Father Time is undefeated,岁月是把杀猪刀。
7月20日,泰森能否胜出?
Formerly known as the "Baddest Man on the Planet," Tyson has been posting clips of his training, and make no mistake, his power is still there.
But he’s no spring chicken.
Of course, there are doubts whether, at his age, he can last the eight rounds, each of which will be two minutes.
Once a man who exuded more confidence than anyone, Tyson obviously knows that Father Time is undefeated, and he was brutally honest about how he feels physically.
"My body is s--- right now," he admitted on Monday. "I’m really sore."

背景
营养策略是对微生物生活方式进行分类的一个重要原则,它是根据微生物偏好的碳源、电子源和电子汇的组合对微生物进行的广义分类。
近期,针对厌氧甲烷氧化古细菌(ANME-1)和深古菌亚群8(Bathyarchaeota subgroup 8,Bathy-8),一种新的营养策略被提出,即化能有机自养(chemoorganoautotrophy)——使用有机碳作为能量来源,同时将无机碳作为唯一的碳源。"
结果
为了进一步探索化能有机自养,我们采用了稳定同位素探针(SIP),使用未标记的有机碳和13C标记的溶解无机碳(13C-DIC)对核酸(rRNA 或 DNA)进行标记,这种方法结合了元基因组学,称为反稳定同位素标记。我们发现,在有甲烷和鳞片磷灰石且无硫酸盐的条件下,ANME-1积极地将13C-DIC纳入RNA中。而在未添加甲烷但添加了纤维素的培养中,ANME-1则同化了有机碳。另一方面,当培养液中加入木质素时,Bathy-8同化了13C-DIC,但它们的DNA来源于无机碳和有机碳的混合,而非仅源自无机碳。根据 SIP 的结果并在元基因组学的支持下,这些古细菌群可能在分解代谢和合成代谢之间进行碳转移,这表明它们具有合成代谢的多功能性。
结论
本研究提供了ANME-1和Bathy-8古菌在自然环境中同化混合有机和无机碳的证据。

【慢跑+拾捡垃圾!“绿色捡跑”在朝阳公园上演】
A hundred runners gathered in Beijing’s Chaoyang Park for a 10-kilometer “cleanup run”, combining jogging with trash collection. This initiative promotes a green and low-carbon lifestyle by integrating running with environmental protection. Several communities in Beijing held “cleanup runs” this year.
百名跑步爱好者齐聚北京朝阳公园,共同开启一场10公里的“绿色捡跑”——慢跑的同时,搜寻拾捡垃圾,通过跑步与环保相结合,倡导绿色低碳的生活方式。今年,“绿色捡跑”已在北京多个社区开展。
