Workers Hold Key to Power in Nature’s Oldest Societies

Some are stronger than others!

A new study analysing how complex, highly-evolved societies are organised in nature has found that it is workers that play a pivotal role in creating well-ordered societies where conflict is minimised. For when it comes to determining who reproduces in ants, University of Leicester biologists have found the humble worker is queenmaker — it is they who choose their queen.

Asian carp aren’t the only invasive species causing trouble in the United States. While the monster fish captures headlines as it inches toward the Great Lakes, other species have already colonized other parts of the country, and are costing plenty of money to control. A finance website has totaled up the toll, listing “10 Invasive Species That Cost the U.S. a Bundle.” See if you agree, disagree, or are just surprised by some of the choices….

New research reveals that chimpanzees in the Congo have developed specialised ‘tool kits’ to forage for army ants.

Chimpanzees in the Congo have developed specialised ‘tool kits’ to forage for army ants, reveals new research published today in the American Journal of Primatology. This not only provides the first direct evidence of multiple tool use in this context, but suggests that chimpanzees have developed a ‘sustainable’ way of harvesting food.

In addition to providing fundamental insights into the early evolution of the estrogen receptor, research by a team at the University of California, San Diego School of Medicine may lead to a contraceptive for female lampreys – a jawless fish considered an invasive pest species in the Great Lakes region of the United States. This could prove important to the Great Lakes region, where lampreys aggressively consume trout, salmon, sturgeon and other game fish.
