2:54 PM | Totally meaningful lists and stuff
Science magazine, ‘inspired’ by Neil Hall’s (borderline?) offensive ‘Kardashian-index’ paper (which has been torn apart by far better people than me, so I’ll just direct you here), has just published a list of ‘The Top 50 Science Stars of Twitter’. Their methods seem strangely flawed for what is considered one of the most prestigious scientific […]

8:42 AM | Dans la tête à Thévenoud, un problème au cerveau?
A quarante ans, ne jamais avoir déclaré ses revenus ni payé son loyer, c'est désormais possible. Thomas Thévenoud l'a prouvé. Rien ne sera plus comme avant. Recalés, tous les cabinets d'optimisation fiscale. Ridiculisés, les habiles conseillers en patrimoine. Thévenoud révolutionne l'art de la fraude. Avec lui il n'y a qu'un seul mot d'ordre : ne rien dire. Le fantôme du fisc, c'est lui. Pour se rafraîchir la […]

1:50 PM | Murmuration over Otmoor
SUMMARY: Tens of thousands of starlings produce spectacular sky shows with their movements at sunset as they gather together every evening during autumn and winter. September has arrived, so you all know what that means: the beginnings of huge bird flocks in autumn and winter! Just as humans spend more time congregating in pubs in autumn and winter, starlings also gather together in large numbers at these times. Every evening as the sun sets, small groups of a dozen or...

4:08 PM | Dolphins and Belugas Squeal With Delight
In a new study, researchers analyzed years of recordings of ‘victory squeals’ – sounds made by dolphins and belugas after they received a fish reward, heard a whistle indicating a reward was forthcoming, or performed a task correctly. The sounds appear to be related to the release of dopamine, indicating they’re related to feelings of pleasure. Read the whole story at Zoologic: Underwater Victory Squeals Signal a Job Well Done .

In this 1st birthday episode, I find out about some more avian criminals of the animal kingdom. I learn that most birds can’t taste sugar, but hummingbirds can, and I learn how. And in the Scientific Spark, I talk to Marlene Zuk, Professor of behavioural and evolutionary biology at the University of Minnesota. Together with Bill Hamilton, Marlene proposed the good genes hypothesis of sexual selection Download the MP3Quicklinks: Maude Baldwin's Science paper on Hummingbird sweet taste […]

1:31 PM | New on Weird & Wild: Mite and Ant Preserved Together
Now here’s a headache of historic proportions: An ancient ant with a mite attached to its head has been found preserved in amber, a new study says. The unlucky ant and its likely parasitic hitchhiker were trapped in tree resin, which eventually fossilized into amber, about 45 million years ago. The discovery is the oldest evidence of a mite attacking a social insect. Read the whole story here: Mite Attacking Ant Entombed in Amber; Oldest Fossil of its Kind .
