When a cold is a cold

What is a galaxy? How Cold is Cold Dark Matter? Recent progress in Near Field Cosmology

There has been a vast recent improvement in photometric and kinematic data for star clusters, Ultra Compact dwarfs, galactic nuclei, and local dSph galaxies, with Subaru contributing substantially to the photometric studies in particular. These data show that there is a bimodal distribution in half-light radii, with stable star clusters always being smaller than 35pc, while stable galaxies are ...

Nhlh2 is a Cold-Responsive Gene

Nescient helix-loop-helix 2 (Nhlh2) is a basic helix-loop-helix transcription factor that functions to communicate signals of energy availability. Based on the expression pattern of Nhlh2 in cold-sensitive areas of the hypothalamus, we hypothesized that mice containing a targeted deletion of Nhlh2 would be unable to maintain body temperature and that Nhlh2 gene expression would vary with cold e...

Is it a cold or the flu?

When we sneeze, does the immune system catch a cold?

Feeling cold is contagious

Seeing someone plunge into an ice-cold bath induces feelings of cold. However, it was recently demonstrated that ie ing another’s skin temperature change also induces a small congruent temperature change in the observer. This synchronization suggests topdown influences on peripheral temperature regulation mechanisms and lends supports to somatic-simulation theories of inter-subjectivity.
