By Greg Hand, University of Cincinnati Fossilized "snapshots" provide University of Cincinnati paleontologist Carlton E. Brett and colleagues with new insights into the behavior of ancient marine creatures. Brett will present this research March 20 at the regional meeting of the Geological Society of America in Pittsburgh. Few specimens inspire greater thrills among fossil collectors than a complete trilobite. These ancient arthropods "“ relatives of lobsters, spiders and insects...

Scientists discover an 'atmospheric imprint' in insects, revealing where they are most likely to survive should climate change alter their ecosystem Scientists have discovered that insects contain atomic clues as to the habitats in which they are most able to survive. The research has important implications for predicting the effects of climate change on the insects, which make up three-quarters of the animal kingdom. Applying a method previously only used to examine the possible effects of...

Surprising new research shows that, contrary to conventional belief, remains of chitin-protein complex"”structural materials containing protein and polysaccharide"”are present in abundance in fossils of arthropods from the Paleozoic era. Previously the oldest molecular signature of chitin-protein complex was discovered in 25 million year old Cenozoic fossils and remnants of structural protein have also been discovered in 80 million-year-old Mesozoic fossils. Carnegie's George Cody...

Entomologists of University Jena are the first to reconstruct a fossil insect completely in 3DIts stay on this planet was actually meant to be a very short one. Male twisted-wing parasites (Strepsiptera) usually have a life span of only few hours. However, accidentally a specimen of Mengea tertiara, about the size of an aphid, became preserved for "Ëœeternity': during its wedding flight about 42 million years ago it was caught in a drop of tree resin and subsequently almost...

Experiments by a team of researchers in New York and New Jersey have generated evidence that questions the common belief that the pterygotid eurypterids ("sea scorpions") were high-level predators in the Paleozoic oceans. This group, which ranged the seas from about 470 to 370 million years ago (long before the dinosaurs appeared), included the largest and, arguably, scariest-looking arthropods known to have evolved on planet Earth. Reaching lengths of 2 ½ meters with a...

Cockroaches can skitter through a crowded under-the-sink cabinet, eluding capture or worse, making the insects a model for rescue robots that would creep through the debris of disaster in search of survivors. But learning how they use all six legs at the same time to walk, run and turn has been a difficult and time-consuming task. Until now. Using a pair of high-speed cameras and a custom computer program, researchers at Case Western Reserve University are able to simultaneously extract...

Insects may have tiny brains the size of a pinhead, but the latest research from the University of Adelaide shows just how clever they really are. For the first time, researchers from the University's Discipline of Physiology have worked out how insects judge the speed of moving objects. It appears that insect brain cells have additional mechanisms which can calculate how to make a controlled landing on a flower or reach a food source. This ability only works in a natural setting. In a paper...

New evidence that specialized adaptations are not evolutionary dead ends Blind scorpions that live in the stygian depths of caves are throwing light on a long-held assumption that specialized adaptations are irreversible evolutionary dead-ends. According to a new phylogenetic analysis of the family Typhlochactidae, scorpions currently living closer to the surface (under stones and in leaf litter) evolved independently on more than one occasion from ancestors adapted to life further below the...

Any way you look at it -- by sheer weight, species diversity or population -- the hard-shelled, joint-legged creepy crawlies called arthropods dominate planet Earth. Because of their success and importance, scientists have been trying for decades to figure out the family relationships that link lobsters to millipedes and cockroaches to tarantulas and find which might have come first. In a scientific and technological tour de force that was nearly a decade in the making, a team of scientists...

A study published today in Science, by researchers at Rothamsted Research (an institute of the BBSRC), the Met Office, the Natural Resources Institute, and the Universities of Exeter, Greenwich and York, sheds new light on the flight behaviors that enable insects to undertake long-distance migrations, and highlights the remarkable abilities of these insect migrants. Many insects avoid cold British winters by migrating south in autumn to over-wintering sites around the Mediterranean. Migrant...

Image Caption: House Centipede, Scutigera coleoptrata. Credit: Bruce Marlin/Wikipedia  (CC BY 3.0) Scutigera coleoptrata is one of many species of house centipedes. This species is native to the Mediterranean, but it is capable of moving to other region of the world including most of Europe, South America, North America, and Asia. It is thought to have first ventured from its native range into Mexico and Guatemala, and its range has now stretched into Argentina in the south and Canada in...

The Jerusalem cricket (Stenopelmatus) is a genus of large, flightless insects native to western United States, along the Pacific Coast, and south into Mexico. Because of its large, human-like head, it is commonly called the nino de la tierra (Spanish for "child of the earth"), or wó see ts'inii (Navajo for "skull insect"). It is also often called the potato bug, or alternatively the old bald-headed man. Despite their name, Jerusalem crickets are not true crickets. Also, Potato bugs are...
