Certain bacteria can build such complex membrane structures that, in terms of complexity and dynamics, look like eukaryotes, i.e., organisms with a distinct…
Memory decline is a part of aging for most people, but very few treatments are available to reverse this loss because the deeper cellular mechanisms underlying…
Regulatory T cells (or “Tregs” for short) play a central role in the human immune system: They guide all of the other immune cells and make sure they are…
Whether they are rocket propellants or fireworks, all explosives contain a fuel and an oxidizing agent. Sometimes both are in the same molecule, like in TNT;…
When egg and sperm combine, the new embryo bustles with activity. Its cells multiply so rapidly they largely ignore their DNA, other than to copy it and to…
These findings were published by researchers at the University of Basel and the Netherlands Institute of Ecology in the online edition of «Journal of Avian…
Two research teams from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the University of Leiden in the Netherlands have…
