Forests, nitrogen and albedo, a very interesting trio indeed

The End of a Very Interesting Year

Canopy nitrogen, carbon assimilation, and albedo in temperate and boreal forests: Functional relations and potential climate feedbacks.

The availability of nitrogen represents a key constraint on carbon cycling in terrestrial ecosystems, and it is largely in this capacity that the role of N in the Earth's climate system has been considered. Despite this, few studies have included continuous variation in plant N status as a driver of broad-scale carbon cycle analyses. This is partly because of uncertainties in how leaf-level phy...

Klippel–Trénaunay Syndrome – A Very Rare and Interesting Syndrome

Klippel-Trénaunay syndrome (KTS or KT) is an infrequently seen dermatological syndrome, which is often viewed as a triad of vascular malformation (capillary malformations or port-wine brands), venous varicosity, and soft tissue and/or bony hypertrophy. We report a case of a 12-year-old male who presented to us with the symptoms of varicose plaques over both lower limbs and was diagnosed as a ca...

Low-cost intradermal rabies vaccination is indeed very promising.

TO THE EDITOR—We read with great interest the recent article by Wieten et al in Clinical Infectious Diseases [1] and, being involved in ongoing research strictly related to this topic, we wish to bring our contribution to their reflections. First, we fully agree that a lower-dose, abbreviated intradermal preand postexposure vaccination schedule may constitute a valid, shorter, and cheaper alter...

Very Cold Indeed: The Nanokelvin Physics of Bose-Einstein Condensation

As atoms get colder, they start to behave more like waves and less like particles. Cool a cloud of identical atoms so cold that the wave of each atom starts to overlap with the wave of its neighbor atom, and all of a sudden you wind up with a sort of quantum identity crisis known as Bose-Einstein condensation. How do we get something that cold? And what is the nature of the strange goop that re...
