In a ‘shocker’ decision, Japan approves mpox drug that failed in two efficacy trials Earlier European authorizations for tecovirimat are also being scrutinized in the face of fresh data

Lots of strange approvals in Japan that neglect trial data.

Microscopic pillars on insect wings give bugs an antibacterial superpower New insights into how these “nanopillars” work could inspire better ways to protect humans from infection

Nanomaterials, due to their size and surface structure, are prone to being harmful to the body, and their strong antibacterial properties are a double-edged sword.

The Power of Adults Over Children: Oppressive or Liberative? Adults can use their power over children in either oppressive or liberative ways.

The goal of parental authority should not be to crush the child’s will and force the child into alignment with the parent’s will. Rather, the goal should be to develop and lift up the child’s will with the child’s well-being in mind.

This title is misleading.
It merely estimates the atmospheric lead concentration during the Roman era from Arctic ice core samples, then estimates blood lead levels from the atmospheric lead concentration, and finally estimates the impact on IQ from those blood lead levels.

It might be an overstatement to claim potential for a polynomial-time exact algorithm, but does it seem promising as a heuristic algorithm??

The decline of the LCD business has led to a shift toward solar cells.
I wonder how long perovskite solar cells will hold up.
As for organic thin-film solar cells, it still seems tough for them to gain traction.

Advent of Rust 2024 - Join the Advent of Code for Rustaceans Advent of Rust is a month-long event where you can learn Rust by solving daily challenges.

Advent of Rust 2024 Completed.
The problems overall followed the specifications of the Rust language, but on Day 20, I had the opportunity to use the type state pattern with PhantomData for the first time.

The Fast Multipole Method (FMM) improves the computational complexity of n-body simulations, such as particle systems, from O(N^2) to O(N). It achieves this by grouping distant particles and calculating their interactions collectively. The Japanese name for this method is "高速多重極展開法".

The context-generic programming (CGP) project, to introduce a new modular programming paradigm for Rust.

If video generation models advance to the point where fake videos can be created freely and indistinguishably from real ones, will images and videos lose their evidentiary value, rendering surveillance cameras meaningless? Ultimately, will it even become possible to install fake memories...?

It might not be very relevant, but I occasionally come across careless mistakes like this.
I've even seen a math professor make such errors.

Analemma - Wikipedia

It is obvious the date of the winter solstice is the same in the northern hemisphere. However, given that the Earth orbits the Sun and its rotational axis is tilted relative to the orbital plane, it seems less obvious due to the variation in the time of solar noon.

There might be another world where distant stars in the universe are home to organisms composed of enantiomers, and chaos ensues when they begin interacting with Earth's life forms, as research on mirror life has made little progress.

Why probability probably doesn’t exist (but it is useful to act like it does) All of statistics and much of science depends on probability — an astonishing achievement, considering no one’s really sure what it is.

> ‘exchangeability’ : starting from a specific, but purely subjective, expression of convictions, we should act as if events were driven by objective chances.

> In our everyday world, probability probably does not exist — but it is often useful to act as if it does.
