In relationships based on mutuality, the number of individuals involved can determine the rate at which species evolve The relationship between species determines how rapidly they evolve. Parasites and their hosts coevolve more rapidly, and partners in a mutualistic relationship can evolve more slowly. But this view is obviously too simplistic. The rate of evolution in a mutualistic relationship does not depend only on the type of interactions, but also on the number of individuals...

As children return to home after a long day at school, they may be carrying with them more than just pencils and books. Head lice, or as some researchers now refer to them, "super lice", because of their resistance to traditional treatment methods, are becoming increasingly difficult to eradicate. Read how one nurse practitioner on Long Island is helping parents fight the battle against these unwelcome house guests at Lice Tamers Head Lice Treatment Center. Huntington Station, NY (PRWEB)...

Lice Connection's Head Lice Removal Specialist Offers Tips for Staying Lice Free This School Year Mount Kisco, NY (PRWEB) September 04, 2012 It´s no coincidence that September is Head Lice Awareness Month. And with good reason. As children head back to school from a summer of camp, all day play dates and mega sleepovers, the number of cases of head lice rises. That´s because head lice, tiny parasitic insects that live on the scalp, are most commonly transferred through head to...

Bees That Go 'Cuckoo' In Nests Of Other Bees

5 new species of cuckoo bees from the Cape Verde Islands The biota of island archipelagos is of considerable interest to biologists. These isolated areas often act as 'evolutionary laboratories', spawning biological diversity rapidly and permitting many mechanisms to be observed and studied over relatively short periods of time. Such islands are often the places of new discoveries, including the documentation of new species. The Republic of Cape Verde comprises 10 inhabited islands...

A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences. This precisely focused therapy combines short strands of "antisense" nucleic acid-like...

New research explains why female cuckoos have evolved different guises To minimize the chance of being recognized and thus attacked by the birds they are trying to parasitize, female cuckoos have evolved different guises. The new research, funded by the Natural Environment Research Council, was published today, 03 August, in the journal Science. The common cuckoo (Cuculus canorus) lays its eggs in the nests of other birds. On hatching, the young cuckoo ejects the host's eggs and chicks...

Pork Tapeworm, Taenia solium
2014-01-12 00:00:00

The pork tapeworm (Taenia solium), also known simply as a tapeworm, is a species of parasitic worm that is classified within the Platyhelminthes phylum. This species infects pigs and humans in many areas of the world including Africa, Southern Europe, Asia, South America, and some areas of North America. This species can cause cysticercosis in its larval stage, which is one of the major causes of seizures in humans. The pork tapeworm can reach an average body length between 2 to 3 meters, but...

Paragonimus westermani
2014-01-12 00:00:00

Paragonimus westermani is a species of fluke, or flatworm that is classified within the Platyhelminthes phylum. This species is abundant in South America and Asia and affects the lungs of humans and other hosts. It was first discovered in 1878 in Europe after two Bengal tigers died. In 1879, Ringer found this species in the lungs of a human. Manson and Erwin von Baelz identified the sputum and eggs separately in 1880, after which Manson asserted that a snail was most likely the worm's...

Echinococcus multilocularis
2014-01-12 00:00:00

Echinococcus multilocularis is a species of tapeworm that is classified within the Platyhelminthes phylum. It is one of a few worms that cause echinococcosis, a disease that affects many canid species including wolves, coyotes, foxes, jackals, domesticated dogs. Humans can also contract this disease. Adult members of this species can reach an average length of .2 inches, and like other species of tapeworm, its body is segmented by three proglottids. Its head, or scolex, is equipped with...

Trichinella spiralis
2014-01-12 00:00:00

Trichinella spiralis, sometimes known as the pork worm, is a parasite within the Nematoda class. It can be found in pigs, rats, humans, and bears. This worm causes trichinosis in humans, most often from consuming undercooked pork. This species is the smallest within its class, reaching an average body length of .16 centimeters. Females are twice as large as males, displaying a sexual dimorphism. The reproductive organs of females are unique to the species in that the front end holds developed...

Guinea Worm, Dracunculus medinensis
2014-01-12 00:00:00

The Guinea worm (Dracunculus medinensis) is a species of roundworm with the Nematoda phylum. This species is once ranged throughout Asia and Africa, including the west coasts of Africa in Guinea. Although it is not present in this range anymore, the species retains its common name. It was identified in this area by Carl Linnaeus, who discovered the parasite in many merchants along the coast. Its scientific name was also given due to a large population in one area, called Medina. Dracunculus...
