‘The data on extreme human ageing is rotten from the inside out’ – Ig Nobel winner Saul Justin Newman
In general, the claims about how long people are living mostly don’t stack up. I’ve tracked down 80% of the people aged over 110 in the [world]. Of those, almost none have a birth certificate. […] [A] Japanese government review in [2010 found] that 82% of the people aged over 100 in Japan turned out to be dead.

(Slightly surprising to me that this wasn’t known, or assumed already. Here’s discussion about the paper on the iNaturalist forum.)
When it comes to butterflies, people prefer pretty ones: That’s a problem for scientists.
[Users] underreported many species, particularly those that were difficult to identify and those with light-colored markings on their wings. Behavioral traits, such as butterflies' flight style and height, and traits that make butterflies difficult to photograph, may have affected reporting patterns, the researchers surmise.

Weather forecasts have become much more accurate; we now need to make them available to everyone
The biggest improvements we’ve seen are for longer timeframes. By the early 2000s, 5-day forecasts were “highly accurate” and 7-day forecasts are reaching that threshold today. 10-day forecasts aren’t quite there yet but are getting better.

Egg-laying caecilian amphibians produce milk for their young, find scientists
The research team observed that the young of the Brazilian caecilian Siphonops annulatus consumed milk for over two months, which appears to be secreted in response to tactile and acoustic stimulation from the mother's cloaca. The milk consists mainly of fats and carbohydrates and is produced in the glands of the female's oviduct.

As Arctic warms, caribou and muskoxen slow biodiversity loss
Diversity declined by about 0.85 species per decade when herbivores were excluded, whereas this decline was only about 0.33 species per decade when they were allowed to graze. The scientists attributed this to herbivores keeping species such as shrubs, dwarf birch and gray willow in check so that other plants could better flourish.

Eläintiede | Loinen tekee sudesta johtajan
Kissoista tarttuva toksoplasma-alkueläin näyttää antavan sudelle johtajan ominaisuuksia, osoittaa tutkimus yhdysvaltalaisen Yellowstonen kansallispuiston susilaumoista. […] Loista kantavat yksilöt jättivät synnyinlaumansa ja perustivat uuden yksitoista kertaa todennäköisemin kuin ne, joilla ei ollut tartuntaa. Laumanjohtajiksi loista kantavat päätyivät peräti 46 kertaa muita todennäköisemmin.
