1. Gen Z Is the First Generation Dumber Than Their Parents (www.vice.com)

For the first time ever, a new generation is officially dumber than the previous one. Congrats, Gen Z, you really did it.

A new study suggests that Gen Z may be scoring lower on intelligence tests compared to their parents’ generation. This trend raises questions about the factors contributing to these cognitive shifts and what it means for the future.

15. They war-gamed dimming the Sun. It went worse than you think (www.wired.com)

Solar geoengineering could buy humanity time against climate changeβ€”or trigger a dangerous new arms race. A first-of-its-kind simulation offered a glimpse of what happens when geopolitics takes the wheel.

A recent simulation reveals the potential risks of solar geoengineering, suggesting that while it might provide temporary relief from climate change, it could also escalate geopolitical tensions and lead to an arms race. The findings raise critical questions about the intersection of technology and international politics in addressing global warming.

Attacks on Trusted Execution Environments (TEEs) raise critical questions about their security. This article encourages a reevaluation of how TEE-based applications are implemented to mitigate potential vulnerabilities.

23. CKKS – Addition and Multiplication (www.jeremykun.com)

Table of Contents
This is part of a tutorial series on the CKKS homomorphic encryption scheme.
In the last article, we introduced symmetric and public-key encryption and decryption routines, and implemented modular polynomial arithmetic (using NTTs as a black box). This article covers the addition and multiplication operations performed on ciphertexts (without relinearization).
Again, if you already know about CKKS, we are still avoiding the RNS form of the scheme and using a 64-bit modulus $Q$, which means that we're momentarily ignoring cryptographic security.

This tutorial continues the CKKS series by detailing how to perform addition and multiplication on ciphertexts without relinearization. It builds on previous concepts of encryption and modular arithmetic, making it a practical guide for those familiar with homomorphic encryption.
