Scientists genetically engineer tomatoes with enhanced folate content

...nd Drug Administration made it mandatory that many grain productssuch as rice, flour and cornmeal be enriched with a synthetic form of folate known as folic acid. Folate deficiencies remain a problem in many underdeveloped countries, however, where adding folic acid is impractical or simply too expensiv...

McBride shows DNA detective work with paper-eating bacteria that 'glide'

...ternatives, such as paper pulp, sawdust, straw and grain hulls. A UWM professor recently helped DOE do just that by analyzing the DNA of a bacterium that can break down cellulose, the major structural component of plants that is also found in forestry by-products (including paper) and waste feedstocks. ...

Radiation therapy combo cures prostate cancer long-term

...mall radioactive pellets, each about the size of a grain of rice. The seeds are inserted into the prostate through small needles during a brief outpatient procedure. External beam radiation therapy involves a series of 25 short daily outpatient treatments, where a radiation oncologist precisely directs hig...

Wheat can fatally starve insect predators

...arts of the wheat plant rather than in the head or grain portions. This will protect the grain quality and the consumer. "Once we understand which genes are active and the timing of the intera...

Researchers find 6,000-year-old fossil evidence

...am. Perry discovered an unknown microfossil starch grain while doing research in Venezuela, and when the other researchers compared notes, they realized that their work in the Bahamas, Panama, Ecuador and Peru also revealed the same unknown starch grain. After studying the starches of many domesticated and...

Custom-made cancer cell attacks

...10 years, because cultivating corn to use only its grain would take up too much land. According to the National Environmental Trust, producing 35 billion gallons of ethanol annually would require putting an additional 129,000 square miles of farmland-an area roughly the combined size of Kansas and Iowa-int...

With cellulosic ethanol, there is no food vs. fuel debate according to MSU scientist

As more and more corn grain is diverted to make ethanol, there have been public concerns about food shortages. However, ethanol made from cellulosic materials instead of corn grain, renders the food vs. fuel debate moot, according to research by a Michigan State University etha...

Unique gene regulation gives chilly bugs survival advantage at bottom of the world

...ns." The Antarctic midge is barely bigger than a grain of rice, but it's still the largest free-roaming terrestrial animal to inhabit Antarctica. The larvae resemble tiny black worms. "It's the largest species that has adapted to living on the continent year-round," said Denlinger, adding that other na...

Engineered yeast speeds ethanol production

More than drought affecting wheat yields

...h of the region shortly before harvest knocked the grain from the heads, Allen said. These seeds germinated into a heavy volunteer wheat crop, which went uncontrolled through the summer. The wheat curl mite over-summered on this "green bridge" and moved into the new crop. Control of volunteer wheat this ...

Producing bio-ethanol from agricultural waste a step closer

...de from sugars derived from corncobs, sugar beets, grain and sugarcane, with the help of baker's yeast. A great number of by-products result from the cultivation of these crops, such as straw and corn husks. It would be a major step forward if this leftover material, which also largely consists of sugar, c...

The Midas Bug -- the bacterial alchemy of gold

'Scent of a woman' tells male redback spiders to find a mate

...backs dwarf the males, who are about the size of a grain of rice. While the females can live for up to two years, males live for only four to eight weeks. Initially, they remain on the web where they were born, but soon disperse when wind conditions are appropriate. Once they settle on their own web they b...

MIT researchers build tiny batteries with viruses

... they hope to build could range from the size of a grain of rice up to the size of existing hearing aid batteries. Batteries consist of two opposite electrodes - an anode and cathode - separated by an electrolyte. In the current work, the MIT team used an intricate assembly process to create the anode. S...

Fruit fly's beating heart helps identify human heart disease genes

... the heart of a fruit fly, an insect the size of a grain of rice. The fly's heart is about the size of the period at the end of this sentence. After perfecting the new visualization technique, the researchers inserted into the fly genome a mutated gene that causes dilated cardiomyopathy in humans. This co...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

...ay. Moreover, Feinberg found that each individual grain in the rock is magnetized in the same direction, meaning that the rock has not been broken up and reformed since it was deposited. This makes extremely unlikely the possibility that the original ash had been weathered into sand that early humans walk...

...al value and optimizing the properties crucial for grain products such as flour, noodles and pasta. "Once the corn genome sequence is in our hands, these advances can happen much faster," Wing said. Corn is one of the most important economic crops in the United States, and, together with rice, accounts f...
