“Oh, hello. I didn’t see you there. I was just editing the weekly roundup of science news for Saturday morning.” This is the first line of my autobiographical one-man play about having multiple Firefox tabs open.
between those tabs? News about the entitlement of quiet people (in the Jane Austen sense), a strange bug and its weird bug genome, and the first confirmation of dark matter filaments.
American entrepreneur/grifter Elizabeth Holmes famously defrauded investors in her blood-testing company Theranos, but she had an important insight backed by research: People respond more favorably to low-pitched voices than high-pitched voices. .
So, at public speaking events, she affected this incredibly distracting, low-pitched voice, which actually might have worked if she dialed it back about 25%. My door is always open to any potential criminal who needs advice about voice pitch.
A cross-cultural study conducted by Penn State researchers confirms that low voice pitch has a big impact on social perceptions. They played audio clips of two male and two female voices to 31,000 participants in 22 countries and then questioned them about their reactions.
Both women and men preferred slower voices for partners in long-term relationships or marriage. Additionally, the lowest-pitched male voices seemed more dominant, especially to younger men, and older men associated the lowest-pitched voices with higher prestige.

Astronomers studying Subaru Telescope data report the observation of dark matter filaments in the nearby Coma Cluster, which extends millions of light years from the Solar System, 321 light years away.
Dark matter is a hypothetical form of matter that tries to explain the discrepancy between the amount of matter observed by astronomers and the gravitational behavior that cannot be explained by general relativity unless more matter is present, for example. , in the observed spin of galaxies. Dark matter is invisible and can only be inferred from its effects on observable baryonic matter in phenomena such as gravitational lensing.
Researchers at Yonsei University used deep data analysis to directly confirm the terminal segments of invisible dark matter filaments associated with the Coma Cluster for the first time.
Scientists in Frankfurt, Müncheberg and Vienna have sequenced the entire genome of the black-necked snake fly, a bug I’d never heard of before because there are so many bugs.
But the snakefly turned out to be a living fossil, a member of a genus that had hundreds of species during the Cretaceous period. After the hypothesized asteroid impact that ended the Cretaceous, only those species that could adapt to the cold survived. The new reference genome gives researchers new insight into the specific genetic changes that allowed snakefly ancestors to survive. It’s really weird looking; Click and see this guy’s neck.
Researchers in France have developed a spiral-shaped IT lens that maintains multifocality regardless of the size of the eye and pupil. The lenses, called spiral diopters, provide advances in contact lenses, intraocular lenses, and miniature cameras.
“For potential implant users or people with age-related farsightedness, this could provide consistently clear vision, potentially revolutionizing ophthalmology,” says Bertrand Simon of the Photonics, Numerical and Nanosciences Laboratory. The spiraling features in the lens are arranged to create multiple points of focus, making it possible to see clearly from a range of distances.
I’m still waiting for the ophthalmology field to develop anamorphic lenses for glasses so I can see the world through cinematic lens flares like in the JJ Abrams movie.
