In the particle world, sometimes two is better than one. Take, for instance, electron pairs. When two electrons are bound together, they can glide through a material without friction, giving the mater...
Nitrogen, an element that is essential for all living cells, makes up about 78 percent of Earth’s atmosphere. However, most organisms cannot make use of this nitrogen until it is converted into ammoni...
Diversity plays a key role in maintaining the stability of plant and animal life. But it's difficult to scale up smaller experiments to understand how changes will impact larger ecosystems.A new study...
Long-time readers of this publication have seen the editors write this introductory note under the heading "Quarterdeck." Despite many months at sea on a variety of research vessels, and 16 months of ...
Infant planetary systems are usually nothing more than swirling disks of gas and dust. Over the course of a few million years, this gas gets sucked into the center of the disk to build a star, while t...
The LHCb collaboration has recently made the world’s most precise measurement of the lifetime of the B+c meson – a fascinating particle that has both beauty and charm.

HIV. Stigma. Gender. These three terms are all-too-frequently used together on any discussion related to
the structural determinants or driving forces of the epidemic. Much time has been devoted to ...
Genetic Diversity of Myanmar and Indonesia Native Chickens Together with Two Jungle Fowl Species by Using 102 Indels Polymorphisms
Genetic Markers Indels Polymorphism Jungle Fowl Native Chicken
2016/5/10
The efficiency of insertion and/or deletion (indels) polymorphisms as genetic markers was evaluated by genotyping 102 indels loci in native chicken populations from Myanmar and Indonesia as well as Re...
Gluing derived equivalences together
Grothendieck constructions oplax functors derived equivalences
2012/4/17
The Grothendieck construction of a diagram X of categories can be seen as a process to construct a single category Gr(X) by gluing categories in the diagram together. Here we formulate diagrams of cat...

a picture of superconductors physical behavior
2010/9/21
For decades, physicists have been trying to reconcile the two major theories that describe physical behavior. The first, Einstein’s theory of general relativity, uses gravity — forces of attraction — ...
