La primavera empieza con millones de pequeñas arquitectas de la naturaleza: las hembras de las abejas silvestres que construyen nidos y llenan el paisaje de vida. Hoy celebramos también a las mujeres que estudian y protegen la biodiversidad.

svmusicology Creadoras de la Historia de la Música

Hoy, #8M, es un día magnífico para que conozcáis el monumental proyecto de la musicóloga @svmusicology.bsky.social y su Mapa de Creadoras.

Una forma muy visual de descubrir compositoras y músicas de todo el mundo, que igual muchas no te suenan por lo que sea.

This Brazilian frog might be the first pollinating amphibian known to science Nectar-loving tree frog likely moves pollen from flower to flower

It’s the first time a frog—or any amphibian—has been observed pollinating a plant, researchers reported in 2023.

Major Chinese funder to stop paying fees for 30 pricey open-access journals Move comes amid effort to grow the country’s own journals

The political effects of X's feed algorithm

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers I’ve read in awhile.

A Shapiro-Wilk test of the response variable concludes very significant deviation of Normality. But residuals of linear model consistent with Normal distribution.

Visual check of the linear model with DHARMa

Periodic reminder that we should avoid testing the Normality of the response variable.

For a linear model, what matters is the Normality of residuals (and not that much). Visual checks better than test. #statistics

Grazalema, Spain, received over 2,000 mm (78 inches) of rain in just the last 20 days.

Over a year’s worth of rain — and it’s only early February. This is hydrologically absurd.

The world is going to blow past the 1.5 C goal of the Paris Accords. Even limiting global warming to 2 C will be very hard.

But we might still be able to pull it off if we change tactics, and focus more attention on climate “Emergency Brakes”.
