By studying seismic waves, researchers have found a layer deep beneath the surface of Mars that could contain enough liquid water to flood the planet with an ocean thousands of feet deep.

Everyone’s seen Rudolph Zallinger’s “The March of Progress” illustration showcasing the evolution of humans: from early primate ape ancestor, Dryopithecus, and progressing toward modern man, Homo sapiens. Evolution is a fascinating phenomenon, but it doesn’t necessarily always follow a straight path as portrayed by Zallinger.

The idea that evolution marches from simple to complex forms, building irreversibly on each prior form has been around for a long time. Paleontologist Louis Dollo’s law states that once an organism progresses with a specialized structure, it does not revert to the previous state.

But now, a new study published in the journal Evolution is challenging the prevailing belief that life progresses unidirectionally. The findings suggest some plants can evolve backward, i.e., specialized species can revert to their more primitive forms.

What, exactly, is your cat thinking? Scientists came up with a questionnaire in 2021 that might give you some idea of where your feline friend fits on what’s known as the triarchic model of psychopathy.

The model measures levels of boldness, meanness, and disinhibition in order to assess overall psychopathic tendencies. Ordinarily, the test is for human beings, of course, but here it’s being applied to cats.

Having completed the survey – which you can find online – you’ll be given what’s called a CAT-Tri+ measure for your pet’s level of psychopathy. The team is hoping that knowing this score can improve human and cat relationships.

One of the most terrifying things about Dune is the fact that it rather accurately predicted what the next front of warfare will look like: genetic warfare. In twenty twenty five, gene manipulation is the biggest threat in the theatre of war, because one gene-altering weapon can render an enemy force infertile at best, and terribly mutated at worst. But that’s not something that happens to the products of breeding programmes in the Dune-verse, at least on a physical level. In this video, we will take a look at every breeding programme in Frank Herbert’s creation, and talk about their horrifying histories in detail.

I was just thinking about the 1871 book Through the Looking-Glass, and What Alice Found There by mathematician, logician, Anglican deacon, writer, and photographer, the Reverend Charles Lutwidge Dodgson (a.k.a. Lewis Carroll).

Lewis Carroll’s Alice’s Adventures in Wonderland and Through the Looking-Glass continue to influence us today, not just as beloved children’s stories but as enduring works that challenge the boundaries of logic, language, and imagination.

At their heart, both books are filled with logical conundrums, puzzling paradoxes, and playful reasoning, reflecting Charles’ background in math and logic. He employed nonsensical situations and absurd dialogues to explore profound ideas about meaning, identity, time, and even mathematics, all disguised within fantastical storytelling.

A new study shows that sound isn’t just heard by the ears. Sound waves altered gene expression and influenced fat cell differentiation in culture.
