Super Mario 64 has been decompiled, in its entirety, basically by hand (writing code until it compiles into the right binary) https://gbatemp.net/threads/super-mario-64-has-been-decompiled.542918/
Chinese scientists guilty of ‘researching while Asian’ in Trump’s America: https://www.scmp.com/magazines/post-magazine/long-reads/article/3016267/chinese-scientists-guilty-researching-while
The story focuses on star cancer researcher Xifeng Wu (https://en.wikipedia.org/wiki/Xifeng_Wu), forced to resign from the University of Texas, apparently because she fostered collaboration with Chinese cancer research institutions at the behest of her higher administration.

University of Strathclyde proposes to axe combinatorics and their three strong combinatorics faculty members: https://cameroncounts.wordpress.com/2019/06/19/combinatorics-at-strathclyde/
This comes despite the group being both strong in research and important in undergraduate education. The apparent cause is Strathclyde's placement of combinatorics in computer science rather than in mathematics and in their use of standards aimed more at computer science than mathematics (like bringing in large grants).
Integer linear programming, change-making, and Presburger arithmetic: https://gilkalai.wordpress.com/2019/03/22/danny-nguyen-and-igor-pak-presburger-arithmetic-problem-solved/
Integer arithmetic problems with O(1) variables and one level of quantifiers (example: given O(1) coin types, find the largest amount of money for which you cannot make change) have long been known to be polynomially solvable, but in FOCS 2017 Nguyen and Pak proved that only two levels of quantifiers make the problem hard.

Some company is advertising by handing out USBs that look like thumb drives, but actually act as keyboards and open the company's webpage on any OS, sometimes by using the windows run dialog. This has given the attack vector more publicity and hopefully will remind people not to plug in random USBs they find. https://v.redd.it/6aygvuaqdq431
If you're interested in the game of Hex, Matthew Seymour's online strategy book is the best one-stop guide to practical play that I know of (and it's not too easy to stumble across):
