Researchers lead by evolutionary and developmental biologist Ulrich Technau at the University of Vienna say that a sea anemone has a genomic landscape that is half animal, half plant.
NSU professor organized and hosted first-ever workshop with experts from across the globe
When the tiny roundworm C. elegans reaches middle age—at about 2 weeks old—it can't quite move like it did in the bloom of youth.
In an era of widespread genetic sequencing, the ability to edit and alter an organism's DNA is a powerful way to explore the information within and how it guides biological function.
A group of German, Belgian and Japanese scientists, coordinated by Professor Ralf Reski from the University of Freiburg, Germany, published a new study where they describe 32,275 protein-encoding genes from the moss Physcomitrella patens.
There's a new actor on the embryology stage: the starlet sea anemone Nematostella vectensis.
Scientists have identified a gene that keeps our nerve fibers from clogging up.
Evolution, often perceived as a series of random changes, might in fact be driven by a simple and repeated genetic solution to an environmental pressure that a broad range of species happen to share, according to new research.
Listed below are the selected highlights for the July 2012 issue of the Genetics Society of America's journal, Genetics.
Microscopes provide valuable insights in the structure and dynamics of cells, in particular when the latter remain in their natural environment.
Arbacia punctulata is a species of Arbacia genus of purple-spined sea urchins. Its natural habitat is in the Western Atlantic Ocean. It can be found in shallow water from Massachusetts to Cuba and the Yucatan Peninsula, from Texas to Florida in the Gulf of Mexico, the coast from Panama to French Guiana and in the Lesser Antilles, normally on sandy, rocky, or shelly bottoms. It is omnivorous, consuming a wide variety of preys. It’s been shown that it is galactolipids, rather than...
Medaka (Oryzias latipes), also known as the Japanese killifish, is a species of ricefish and the only member of the Oryziinae subfamily. It is native to Southeast Asia and is a common occupant of rice paddies in coastal Asia. It is amphidromous, meaning it moves between salt and freshwater at some point during life, and for this reason, is found in both ocean and river habitats. This is a small fish, reaching lengths of 0.75 to 1.55 inches. Due to its hardiness and pleasant coloration,...
Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...
The Medaka, also known as the Japanese killifish (Oryzias latipes) is part of the genus Oryzias (ricefish) - the only genus in the family Oryziinae. These natives of Southeast Asia are rather small measuring about 1-2 inches. The Medaka is also a native of rice paddies in coastal Asia. Because of the Medaka's enjoyable coloration and hardiness it is a popular aquarium fish. Medaka's coloration ranges from brown or yellow-gold in the wild, to white along with creamy yellow or orange. Since the...
The Zebrafish (Danio rerio) is a tropical fish belonging to the minnow family (Cyprinidae). It is a popular aquarium fish, where it is frequently sold under the trade name Zebra danio, and is also an important model organism. Characteristics The zebrafish arose in the Ganges region in Eastern India and is also native to Pakistan, Bangladesh, Nepal and Myanmar. It commonly inhabits streams, canals, ditches, ponds and slow-moving to stagnant water bodies, including rice fields. The...
- Any of various tropical Old World birds of the family Indicatoridae, some species of which lead people or animals to the nests of wild honeybees. The birds eat the wax and larvae that remain after the nest has been destroyed for its honey.
