You may have read that Asian cultures respect the elderly more than Europe but Asian senior citizens may not agree. However, it may not be that young people have gotten less respectful, it could be that young people are wealthier than in the past. And that makes them lonelier.

Over the last 40 years, the wealth of countries like the United States and Japan have increased substantially. Poor people now have a life that the poor even two generations ago could not imagine would be possible. Yet a new cross-temporal meta-analysis says that despite the changes in wealth which make socializing more possible, young people report more loneliness.

A new tool drawing on billions of uses of more than 20,000 words and diverse real-world texts claims to have found that human language is systematically biased, but not against things. It is instead biased toward safety and that has impacted everything from psychology claims to how Large Language Models (LLMs, colloquially called Artificial Intelligence and AI).

There are concerns about projected warming on the Earth’s surface and in the lower atmosphere even while the planet’s upper atmosphere has cooled.

It's not a paradox, it's a pattern and a recent paper described the mechanics of how it works. The short answer is that carbon dioxide (CO2) reacts differently to wavelengths of light. Closer to earth, CO2 traps it but it makes the stratosphere better at radiating, which cools it—but because it becomes colder, the Earth system ends up losing less heat to space overall, strengthening warming below.

We may use terms like "grounded" and terra firma to mean stability and consistency but geology laughs at that notion. The next time you go on vacation, a new tool can show you how many places your vacation destination has been. 

Paleolatitude.org can do that, right down to the movements of small tectonic and ‘lost continents’ now called Greater Adria, the Tethys Himalayas or Argoland, which we know as  folded rocks in the mountain ranges of the Mediterranean, the Himalayas, and Indonesia. 

One tenet of natural selection is a random walk of genes but nature may be more predictable than rolls of dice suggest. A new study of the mimicry of several distantly-related South American rainforest butterfly and moth species with similar wing color patterns that may warn away predators (it's not a costumed bluff, the moths and butterflies are actually toxic to birds) found that they reused the same two genes - ivory and optix - to evolve near identical color patterns.

There are many hypothetical particles proposed to explain dark matter and one idea to explore how strongly hypothetical dark photons interact with normal photons wouldn't even involve a new and expensive dedicated facility, says Tokyo Metropolitan University Associate Professor Wen Yin.
