Did We Already Have the Data to Show Dark Matter Annihilation?
Dan Hooper, & Lisa Goodenough (2010). Dark Matter Annihilation in The Galactic Center As Seen by the Fermi Gamma Ray Space Telescope arXiv arXiv: 1010.2752v1
Analyzing old data from the Fermi Gamma Ray Space Telescope, the authors have noticed gamma ray emissions consistent with predictions for a certain type of dark matter. Unfortunately, these things are never nice, clea........ Read more »

From rising temperatures to rising seas, the consequences of global warming are here now, and predictions for the future are dire. In his review “Drought under global warming,” UCAR author Aiguo Dai indicates that yet another consequence is already affecting our planet and, over time, will almost certainly become more severe: worldwide drought.

I have previously suggested that to prevent and treat childhood obesity, interventions need to focus on the parents and not the kids.

The idea that humans are social animals has become a truism. Among other things, experts point to the gregarious behaviour of babies - their precocious talents for mimicry and face recognition. What about human behaviour pre-birth? Is that social too? Using what they call the 'experiment of nature' provided by twin fetuses, Umberto Castiello and his team have shown that by the 14th week of gestation, unborn twins are already directing arm movements at each other, and by the 18th week these 'soci........

Placebos – the inert substances taken by control groups in clinical trials – are often assumed to be harmless sugar pills or something along those lines. New research has found that actually it’s impossible to know what’s in placebos because there’s precious little documentation of what exactly is used in clinical trials. Out of 176 [...]...

A recent post by Miko on Kirschner and Gerhart’s work on developmental constraints and the implications for evolutionary biology caught my eye due to the possible analogues which could be drawn with language in mind. It starts by saying that developmental constraints are the most intuitive out of all of the known constraints on phenotypic variation. Essentially, whatever evolves must evolve from the starting point, and it cannot ignore the features of the original. Thus, a winged horse would ........ Read more »

Opisthobranch molluscs (aka nudibranchs) present and interesting scenario to behavioral ecologists because they have evolutionarily dispensed of a gastropods’ best line of predator defense: the shell.
