Northern Mockingbird (Mimus polyglottos) Mockingbirds are one of the most commonly noticed birds in the state. They are either applauded for their audaciousness or cursed for their persistence in nocturnal singing or in the defense of their territory. Insects, fruit, crustaceans and small vertebrates make up the mockingbird's diet. The fact that they enjoy fresh fruits and vegetables hasn't exactly made them gardeners' friends either, although they do eat lots of insects. Mockingbirds are found in just about every habitat type in the state. The males' territoriality and constant singing and displaying during the breeding season make them the most noticeable bird in Texas.
Unmated male mockingbirds sing more than mated ones, and only unmated males sing at night. Trichonympha. Trichonympha is a genus of parabasalian protists that live in the intestines of many, if not most, termite species. They are symbiotes,[1] in that they break down the cellulose in the wood and plant fibers their hosts eat. Trichonympha resembles teardrops or pears that are wearing wigs. They are extremely motile, and feed by engulfing wood and plant fibers through phagocytosis, which always occurs at the broad ends of their bodies. As beguiling as a relationship between a wood-eating insect (xylophagous) and its wood-digesting symbiote may seem, further investigations of Trichonympha reveals even more mind-boggling situations.
By itself, Trichonympha lacks the ability to produce cellulase; it requires bacterial endosymbiotes to produce the cellulase to digest its food. It also has spirochete ectosymbiotes embedded in its cell membrane, and together with its flagella these symbiotes give their host its characteristic "wiggy" appearance to grant it motility. Endosymbiont. An endosymbiont is any organism that lives within the body or cells of another organism, i.e. forming an endosymbiosis (Greek: ἔνδον endon "within", σύν syn "together" and βίωσις biosis "living"). Examples are nitrogen-fixing bacteria (called rhizobia), which live in root nodules on legume roots, single-cell algae inside reef-building corals, and bacterial endosymbionts that provide essential nutrients to about 10–15% of insects. Many instances of endosymbiosis are obligate; that is, either the endosymbiont or the host cannot survive without the other, such as the gutless marine worms of the genus Riftia, which get nutrition from their endosymbiotic bacteria.
The most common examples of obligate endosymbioses are mitochondria and chloroplasts. Some human parasites, e.g. It is generally agreed that certain organelles of the eukaryotic cell, especially mitochondria and plastids such as chloroplasts, originated as bacterial endosymbionts. Endosymbionts in protists[edit] Daily dose of beet juice promotes brain health in older adults. Researchers for the first time have shown that drinking beet juice can increase blood flow to the brain in older adults -- a finding that could hold great potential for combating the progression of dementia. The research findings are available online in Nitric Oxide: Biology and Chemistry, the peer-reviewed journal of the Nitric Oxide Society and will be available in print soon.
"There have been several very high-profile studies showing that drinking beet juice can lower blood pressure, but we wanted to show that drinking beet juice also increases perfusion, or blood flow, to the brain," said Daniel Kim-Shapiro, director of Wake Forest University's Translational Science Center; Fostering Independence in Aging. "There are areas in the brain that become poorly perfused as you age, and that's believed to be associated with dementia and poor cognition.

The 2006 NASA ST5 spacecraft antenna. This complicated shape was found by an evolutionary computer design program to create the best radiation pattern. Genetic algorithms find application in bioinformatics, phylogenetics, computational science, engineering, economics, chemistry, manufacturing, mathematics, physics, pharmacometrics and other fields.
Methodology[edit] In a genetic algorithm, a population of candidate solutions (called individuals, creatures, or phenotypes) to an optimization problem is evolved toward better solutions. Each candidate solution has a set of properties (its chromosomes or genotype) which can be mutated and altered; traditionally, solutions are represented in binary as strings of 0s and 1s, but other encodings are also possible. A typical genetic algorithm requires: a genetic representation of the solution domain,a fitness function to evaluate the solution domain.

British Engineer Designs Own Heart Valve Implant, Saves Own Life. In 2000, Tal Golesworthy, a British engineer, was told that he suffers from Marfan syndrome, a disorder of the connective tissue that often causes rupturing of the aorta.
The only solution then available was the pairing of a mechanical valve and a highly risky blood thinner. To an engineer like Golesworthy, that just wasn't good enough. So he constructed his own implant that does the job better than the existing solution--and became the first patient to try it. The existing fix, called the Bentall surgery, requires a five-hour invasive slice-and-dice and a heart-lung bypass, after which the damaged part of the aorta is cut out and replaced with a graft and mechanical valve.
But Golesworthy saw an opportunity instead of despair: Nobody had thought to use more modern technologies, namely combining MRI tests with computer-aided design tools and new rapid prototyping techniques. [The Engineer via Boing Boing] Termite. Like ants, and some bees and wasps—which are all placed in the separate order Hymenoptera—termites divide labor among castes, produce overlapping generations and take care of young collectively. Termites mostly feed on dead plant material, generally in the form of wood, leaf litter, soil, or animal dung, and about 10% of the estimated 4,000 species (about 3,106 taxonomically known) are economically significant as pests that can cause serious structural damage to buildings, crops or plantation forests.
Termites are major detritivores, particularly in the subtropical and tropical regions, and their recycling of wood and other plant matter is of considerable ecological importance. As eusocial insects, termites live in colonies that, at maturity, number from several hundred to several million individuals.

One thing we've learned during our extensive research here at Cracked is that animals are more and more amazing the more you learn about them. But there's a point on the graph where they're a little too amazing, and then it crosses into "unsettling. " So we're not sure how to feel about the fact that... Chimpanzees Go to War You'd think "Chimpanzee Researcher" would be the most hilarious job in the world, what with the subjects always putting on people clothes and pretending to smoke pipes. But during a 10-year study of a community of chimps in Uganda, scientists found something terrifying. More terrifying than the Congo chimp's alliance with the Clown People.
Every once in a while groups of strong chimp males would form up and head north, toward the border between their territory and the land of the neighboring tribe. Then they did it again.

Visual Thinking. Mirlen101. Psychobotany. The Secret Life of Plants. It means even on the lower levels of life, there is a profound consciousness or awareness that bonds all things together. Published in 1973, The Secret Life of Plants was written by Peter Tompkins and Christopher Bird. It is described as “A fascinating account of the physical, emotional, and spiritual relations between plants and man.” Essentially, the subject of the book is the idea that plants may be sentient, despite their lack of a nervous system and a brain. This sentience is observed primarily through changes in the plant’s conductivity, as through a polygraph, as pioneered by Cleve Backster. The book also contains a summary of Goethe’s theory of plant metamorphosis. That said, this book is about much more than just plants; it delves quite deeply into such topics as the aura, psychophysics, orgone, radionics, kirlian photography, magnetism/magnetotropism, bioelectrics, dowsing, and the history of science.

Personnalisations. Bioliteracy Project Home Page. Home. Hypertextbook Chapters. BioFundamentals © UC Boulder and virtuallaboratory.net, inc. Interactive Biology. Interactive Biology Serendip sees the web as a tool which can make education a more interactive and exploratory process, by making freely available educational resources at a variety of levels and also, even more importantly, be making it increasingly possible to learn by doing (see Serendip's web principles and credo on education and technology). To encourage understanding and use of the web in this way, Serendip provides annotated lists of links useful for learning/teaching in a variety of areas (see Interactive Physics and Interactive Chemistry). The focus is not on course syllabi or notes but rather on materials from which individuals can learn themselves, and particularly on those with an interactive component.
This list and annotations was created by Katie DiFelice. Links were last checked July 2005 by Yaena Park and August 2007 by Ashley Dawkins. Suggestions for additions to the list are warmly welcomed and should be sent to Serendip. Additional Resources.

Earth/Life Sciences and Discoveries. Prokaryotic and Eukaryotic Cells. Part of our definition/description of what it means to be a living thing on Earth includes the assertion that living things are made of cells and cell products. In other words, we consider the cell to be a pretty fundamental structural aspect of life. Cells in our world come in two basic types, prokaryotic and eukaryotic. "Karyose" comes from a Greek word which means "kernel," as in a kernel of grain. In biology, we use this word root to refer to the nucleus of a cell. Here's a simple visual comparison between a prokaryotic cell and a eukaryotic cell: This particular eukaryotic cell happens to be an animal cell, but the cells of plants, fungi and protists are also eukaryotic.
Despite their apparent differences, these two cell types have a lot in common. Some things which seem to be differences aren't. Despite all of these similarities, the differences are also clear. If we take a closer look at the comparison of these cells, we see the following differences: Introduction to Cellular Respiration. A Basic Primer on Biotechnology. Frend.
