2011-12-09 06:07:57

Researchers report that they have uncovered and analyzed human bedding believed to be 77,000 years old. The bedding material gives a look into how humans lived in South Africa. Lyn Wadley of the University of the Witwatersrand in Johannesburg, South Africa says, “Domestic activities, like preparing and destroying plant bedding, can provide important information.” Some of the important information provided in the plant-based bedding materials, according to the National...

New grass family tree reveals C4 photosynthesis is an evolutionary 1-way street If you eat bread stuffing or grain-fed turkey this Thanksgiving, give thanks to the grasses – a family of plants that includes wheat, oats, corn and rice. Some grasses, such as corn and sugar cane, have evolved a unique way of harvesting energy from the sun that's more efficient in hot, arid conditions. A new grass family tree reveals how this mode of photosynthesis came to be. The results may one day...

The carbon footprint of humans will be reduced by four awards for plant and microbial research issued under a new joint U.S./Japanese program Four joint United States and Japanese research teams have been awarded funding totaling about $12 million (about Yen 960 million) to develop new environmentally-friendly techniques to increase the production of renewable biofuel and reduce pesticide use. These environmentally-friendly techniques will be based on studies of metabolites--chemical...

Important changes that will affect the publication of new names in algae, fungi, and plants accepted by the XVIII International Botanical Congress are detailed in a paper that is being published simultaneously or will be published soon in a total of sixteen leading academic journals. The paper, co-authored by Sandra Knapp (London), John McNeill (Edinburgh) and Nicholas Turland (St. Louis), presents the draft text of new articles to the Code and some ideas for best practice for authors and...

Botanical taxonomy, which extends to include the formal scientific naming of all plants, algae and fungi has gone through a landmark change in the procedure scientists need to follow when they describe new species. Details of the forthcoming changes to the newly-named 'International Code of Nomenclature for algae, fungi and plants' are laid out by Dr Sandra Knapp and colleagues in an article published in BioMed Central's open access journal BMC Evolutionary Biology. It has been suggested that...

Vats of blue-green algae could one day replace oil wells in producing raw materials for the chemical industry, a UC Davis chemist predicts. Shota Atsumi, an assistant professor of chemistry, is using “synthetic biology” to create cyanobacteria, or blue-green algae, that convert carbon dioxide in the air into complex hydrocarbons, all powered by sunlight. Cyanobacteria are single-celled organisms that, like green plants, can use sunlight to turn carbon dioxide and water into...

Road maintenance may accidentally spread the seeds of invasice plants, according to Penn State researchers. "The road graders that are used during these operations can act like a plow, pushing seeds along the road," said Emily Rauschert, senior project associate and applied ecologist in crop and soil sciences. "They can pick up seeds of an invasive grass and spread them several orders of magnitude further than the natural dispersal." The researchers created a computer simulation based on...

The Nomenclature Section of the 18th International Botanical Congress in Melbourne, in July 2011, proposed and approved sweeping changes to the way scientists name new plants, algae, and fungi. To demonstrate the efficiency of electronic publishing, the first open access plant taxonomy journal PhytoKeys published a correspondence note by a team of botanists from various USA institutions (Smithsonian Institution, The Missouri Botanical Garden, The Chicago Botanical Garden, and The Field Museum...

Dawsonia
2013-11-04 10:01:23

Dawsonia is a classification of mosses. This genus is a member of the Polytrichaceae family. Dawsonia plants are commonly known to grow taller and have thicker leaves than other common mosses. Mosses are known to grow when hydrated, however most common mosses lack cuticles and internal transport tissues. This makes it difficult for them to maintain substantial amounts of water and they typically do not grow tall. Dawsonia are an exception to this common rule. Dawsonia mosses are...

Petrified Forest National Park
2013-04-24 16:53:26

Petrified Forest National Park is located in the state of Arizona in the United States. The park holds 221,552 acres of land, of which 50,260 acres are comprised of a designated wilderness. The area was once inhabited by Native American tribes including the basket maker and pueblo peoples. The first American explorers to enter the area arrived while searching for good routes leading from east to west. This group, led by Army Lieutenant Amiel Whipple, surveyed the northern area of the...

The Whisk Fern (Psilotum nudum), is a genus of fern-like vascular plants, one of two genera in the family Psilotaceae, order Psilotales, and class Psilotopsida (the other being Tmesipteris). The distribution of Psilotum is tropical and subtropical, in the New World, Asia, and the Pacific. The highest latitudes known are in South Carolina and southern Japan for P. nudum. In the U.S., one species is found from Florida to Texas, the other in Hawaii. They had traditionally been thought not to...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
