Ever wondered about the science behind the seasoning of cast-iron pans and how it makes them non-stick? The latest edition of Periodic Graphics in C&EN takes a look: cen.acs.org/food/food-science/

Astronomers used the Event Horizon Telescope to capture the first polarized light image of the Milky Way’s supermassive black hole, Sagittarius A

This breakthrough suggests that all black holes may possess strong magnetic fields, challenging previous understanding.

The image also hints at the presence of a hidden jet emanating from the Milky Way’s black hole. Wow!

Flaco的尸检结果出来了。报告显示它体内检测出了大量鼠药(多达四种)和鸽疱疹病毒,导致了严重的软组织受损和多个器官的炎症,因此,即便它没有因鸟撞而死,最终也会死于对老鼠和野鸽的长期捕食。在它体内甚至还有微量DDE,虽说DDT已于1970s被禁。
而这就是众多城市猛禽面临的共同处境……

好多年没去需要business casual的场合了,临阵磨枪买了双有跟的鞋穿。虽然走久了脚痛贴满了创口贴,但有个意外体会:原来高一寸人生体验已经大不同,最大的差别是跟个高个子同事讲话脖子不疼了。以前是他常常和另外一个更高的同事一起出没,我跟他们讲话需要退后一步,不然聊一下脖子就要折了。

Overconfident humans who don’t listen to anybody else scare the hell out of me.

As any houseplant owner knows, so much of a plant's success comes down to how the roots are doing. In botany, researchers are increasingly looking to the oft-overlooked roots to answer questions about plant evolution and physiology, in a discipline semi-jokingly called "shovelomics".

翻这本书,有几个想法:
1. 原来Apollo 10的crew最倒霉,他们做了所有Apollo 11要做的tasks,除了登陆。但没有人记得他们的名字。apollo8虽然也去绕了月亮,但因为是人类第一次,也算是第一。10就没有
2. Apollo8的Jim Lovell,就是史上唯一一个绕过两次月亮,但都没能落地的那个,是11的backup crew。也就是说,如果Armstrong临时食物中毒了不能飞,他就是one giant leap的那个。
3. 而且原来prelaunch check是backup crew做的。
4. 书的前言说得非常好,说:Apollo 11 was the result of an unprecedented symbiosis of political will and technological capability. 说有人质疑去月球意义何在,他的答复是:登月带来了infrastructure and technology, 带来了knowledge and experience。这个确实如此,登月带来的技术革新渗入到我们现代生活的方方面面。
