Using a method based on geographic positioning systems that allowed them to characterize the topography of the bats' molars in a way similar to how geographers characterize mountain surfaces, the researchers calculated a measure of dental complexity that reflects how "rugged" the surface of the tooth is. They illustrate a trend from relative simplicity of the shearing molars in insect eaters and omnivores to high complexity of the crushing molars in fruit eaters. Working with field-collected...

Common genetic recipes pattern organs as different as shark gills and human hands A SCUBA expedition in Australia and New Zealand to find the rare embryos of an unusual shark cousin enabled American and British researchers to confirm new developmental similarities between fish and mammals. Elephant fish, a relative of sharks, utilize the same genetic process for forming skeletal gill covers that lizards and mammals use to form fingers and toes, researchers at the University of Chicago and the...

To survive in a tumultuous environment, sea urchins literally eat through stone, using their teeth to carve out nooks where the spiny creatures hide from predators and protect themselves from the crashing surf on the rocky shores and tide pools where they live. The rock-boring behavior is astonishing, scientists agree, but what is truly remarkable is that, despite constant grinding and scraping on stone, urchin teeth never, ever get dull. The secret of their ever-sharp qualities has puzzled...

Knocked out teeth can be saved for life but must be stored in a Save-A-Tooth system within the first hour of the accident. That's why they should be a part of every first aid kit. Wayne, PA (PRWEB) December 5, 2010 The Mayo Clinic advises that a well-stocked first aid kit can help people respond effectively to common injuries and emergencies. They feel that people should keep at least one first-aid kit at home and one in their car. Among many other items in the kit, the Mayo Clinic...

KREFELD, Germany, October 14, 2010 /PRNewswire/ -- - The Daily Battle in the Bathroom To many children, brushing their teeth is just a cumbersome chore, which leads to the same old frustrating battle in the bathroom between parents and their offspring. But now Krefeld-based psychiatrist Dr Einhardt Illing has developed an iPhone app which provides guidance and motivation for brushing. And a little bit of fun to boot. The new tooth brushing motivator "Motivetrix" guides the...

TAU develops method for determining the diet of our early ancestors Were our early mammalian ancestors vegetarians, vegans or omnivores? It's difficult for anthropologists to determine the diet of early mammalians because current fossil analysis provides too little information. But a new method that measures the size of chips in tooth fossils can help determine the kinds of foods these early humans consumed. Prof. Herzl Chai of Tel Aviv University's School of Mechanical Engineering, in...

It's a question that has puzzled scientists for years: why, in some species of spiders, are the females so much larger than their male counterparts? Now, investigators from the Spanish National Research Council (CSIC) believe they have found the answer. According to their findings, which are published in Wednesday's edition of the open access journal BMC Evolutionary Biology, the cause is likely tied to bridging, a technique of transportation used by some spiders to cross large gaps. When...

Leaded gasoline was responsible for about two-thirds of toxic lead that African-American children in Cleveland ingested or inhaled during the latter two-thirds of the 20th century, according to a new study in Science of the Total Environment. Researchers from Case Western Reserve University say what they've shown in Cleveland probably applies to many cities across the U.S. and reinforces concerns about the health threat for children in countries still using leaded gasoline. However, they...

The findings provide clues to how our brains work Scientists from The Scripps Research Institute have found a specific chemical compound secreted by many predators that makes mice behave fearfully. The research helps scientists better understand animal behavior, and may eventually lead to new insights into how sensory information is processed in human brains. The research was published in the prestigious journal Cell on May 14, 2010. "We're interested in how the brain can be hardwired to...

Each cusp of our teeth is regulated by genes which carefully control the development. A similar genetic puzzle also regulates the differentiation of our other organs and of all living organisms. A team of researchers at the Institute of Biotechnology of the University of Helsinki has developed a computer model reproducing population-level variation in complex structures like teeth and organs. The research takes a step towards the growing of correctly shaped teeth and other organs. The results...

Atlantic Fire Ascidian, Pyrosoma atlanticum
2014-01-12 00:00:00

Pyrosoma atlanticum is a species of colonial tunicate found in temperate waters worldwide, usually between 50°N and 50°S. It is most plentiful at depths below 800 feet. It is found in colonies that are pelagic and move throughout the water column. In the evening the colony will move closer to the surface and descend back by dawn. Large colonies can rise and descend more than 2,500 feet in a single day. A colony of this species is cylindrical and can grow up to 2 feet long and 2.5 inches...

Heterodontosaurus, meaning "different toothed lizard", is a genus of dinosaur from the Early Jurassic Period of what is now South Africa. The type species, H. tucki, was found in the Upper Elliot Formation of the Hettangian age (199 to 196 million years ago). Two species are known. This herbivorous dinosaur ate mostly plants despite having canines. It was a small ornithischian reaching a total length of 3 feet. It had a long, narrow pelvic bone which was like more advanced ornithischians....

The Giant Pangolin (Manis gigantea), is a species of pangolin. The Giant Pangolin inhabits Africa with a range stretching along the Equator from West Africa to Uganda. It is found mainly in savanna, rainforest, and forest, where there is a large termite population and available water. It does not inhabit high altitude areas. The Giant Pangolin is the largest species of pangolin (scaly anteaters). It belongs to the Manidae family. It was first described by Johann Karl Wilhelm Illiger in 1815....

The Southern Alligator Lizard, Elgaria multicarinata, is a lizard native to the Pacific coast of North America. It is common throughout Southern California and can be found in both grasslands and urban areas. Several subspecies can be distinguished, including the San Diego alligator lizard. It has a prehensile tail up to twice the length of its body. Like many lizards, however, it can drop its tail if attacked, possibly giving it a chance to flee; the tail will regenerate, but will never...

The Triplewart seadevil, Cryptopsaras couesii, is a seadevil of the family Ceratiidae, found in all oceans, from the surface to 1.24 mi (2,000 m). Its length is approximately 11.81 in (30 cm). The Triplewart seadevil is one of the most abundant of the deepwater anglerfish. These fish have round flabby bodies with a soft fibrous skeleton and a scaleless prickly skin. Like most other deepwater anglerfishes this fish has small eyes, no pelvic fins and is colored black. It has a large...
