As we grow older, it's essential to pay attention to our bodies and how they're changing -- including our mouths. Yes, our mouths. Paying close attention to your teeth as you age is important because they need more care as you get older. Plus, older people tend to be more prone to certain oral health issues. "Teeth take quite a journey as time goes by," says cosmetic dentist Dr. David Wagner, DDS, adding that your mouth also goes through a journey. "As we age, our mouths go through some interes

A team of astronomers announced this week that they've detected a possible sign of life on an exoplanet 124 light years away using the James Webb Space Telescope. Even more enticingly, the exoplanet, dubbed K2-12b, was already suspected to be an ocean world. The biosignature is a molecule called dimethyl sulfide. On Earth, it's exclusively produced by phytoplanktons and other microbes. Thus, the authors of the new study, published in The Astrophysical Journal Letters, maintain that the best exp

Astronomers say they've found "the most promising signs yet" of chemicals on a planet beyond our Solar System that could indicate the presence of life on its surface. Using the James Webb Space Telescope, the team found a possible 'biosignature' – the potential fingerprint of life – within its atmosphere, although they say they're remaining "cautious", and that this isn't a confirmed detection. The chemicals detected are the same as those produced by marine-dwelling organisms on Earth. The te

Scoped values are easier to reason about than thread-local variables. They also have lower space and time costs, especially when used together with virtual threads (JEP 444) and structured concurrency (JEP 505).

In practice, the lever escapement is king. If you own a mechanical watch, there is a very high probability it utilizes the lever, from Seiko 5s to every prior Rolex ever made. The Crown introduced a proprietary lever escapement in 2015 — the Chronergy escapement. Even with ultra-optimized geometry like in the Chronergy system, any lever escapement has a few fundamental flaws. The most significant of which is the lever's inherent friction and, therefore, need for lubrication. Just by glancing at

Tail Call Recursion in Java with ASM One kind of optimization offered by some compilers is tail call optimization. This optimization does not bring much, since the programmer can always tailor his code without recursion, especially in an imperative language. On the other side, recursive code often times more elegant, so why we don’t let the compiler do the nasty stuff when it is possible? In this article I will present a neat way to implement tail call optimization in Java using byte code manip

In many robotics and VR/AR applications, fast camera motions cause a high level of motion blur, causing existing camera pose estimation methods to fail. In this work, we propose a novel framework that leverages motion blur as a rich cue for motion estimation rather than treating it as an unwanted artifact. Our approach works by predicting a dense motion flow field and a monocular depth map directly from a single motion-blurred image. We then recover the instantaneous camera velocity by solving a
