Collaboration Encourages Equal Sharing in Children but Not in Chimpanzees

Published: July 20, 2011.
By Max-Planck-Gesellschaft
http://www.mpg.de

Katharina Hamann with an international team of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, Harvard University and the Michigan State University found that sharing in children that young is a pure collaborative phenomenon: when kids received rewards not cooperatively but as a windfall, or worked individually next to one another, they kept the majority of toys for themselves. One of humans' closest living relatives, chimpanzees, did not show this connection between sharing resources and collaborative efforts. …

How the Zebrafish Gets Its Stripes
The zebrafish, a small fresh water fish, owes its name to a striking pattern of blue stripes alternating with golden stripes. Three major pigment cell types, black cells, reflective silvery cells, and yellow cells emerge during growth in the skin of the tiny juvenile fish and arrange as a multilayered mosaic to compose the characteristic colour pattern.

Potential Therapy for Incurable Charcot-Marie-Tooth Disease
Charcot-Marie-Tooth disease type 1A is the most common inherited disease affecting the peripheral nervous system. Researchers from the Department of Neurogenetics at the Max Planck Institute of Experimental Medicine and University Medical Centre Göttingen have discovered that the maturity of Schwann cells is impaired in rats with the disease. These cells enwrap the nerve fibres with an insulating layer known as myelin, which facilitates the rapid transfer of electrical impulses. If Schwann cells cannot mature correctly, an insufficient number of nerve fibres is…

Researchers Block Plant Hormone
Researchers trying to get new information about the metabolism of plants can switch off individual genes and study the resulting changes. However, Erich Kombrink from the Max Planck Institute for Plant Breeding Research in Cologne and Markus Kaiser from the University of Duisburg-Essen adopt a different approach. They identify small molecules that block specific components of the metabolic process like brake pads and prevent the downstream reactions. In their search for these molecules, they use a biological selection process involving intact plants. This…

500 Million Year Reset for the Immune System
Scientists at the Max Planck Institute of Immunobiology and Epigenetics (MPI-IE) in Freiburg re-activated expression of an ancient gene, which is not normally expressed in the mammalian immune system, and found that the animals developed a fish-like thymus. To the researchers surprise, while the mammalian thymus is utilized exclusively for T cell maturation, the reset thymus produced not only T cells, but also served as a maturation site for B cells – a property normally seen only in the thymus of fish. Thus…

Potential Treatment And Prevention of Parkinson's Disease
Parkinson's disease affects neurons in the Substantia nigra brain region – their mitochondrial activity ceases and the cells die. Researchers at the Max Planck Institute of Molecular Cell Biology and Genetics show that supplying D-lactate or glycolate, two products of the gene DJ-1, can stop and even counteract this process: Adding the substances to cultured HeLa cells and to cells of the nematode C. elegans restored the activity of mitochondria and prevented the degeneration of neurons. They also showed that the two substances…
