Researchers at Queen Mary University of London have shown for the first time that the specialised role stem cells go on to perform is controlled by primary cilia –tiny hair-like structures protruding from a cell.
University of Calgary scientists have discovered metabolic enzymes in the opium poppy that play "widespread roles" in enabling the plant to make painkilling morphine and codeine, and other important compounds.
Plant-based biofuels were initially hailed as the answer to all problems posed by traditional fossil fuels. Supply is unlimited and they are also neutral to emissions harmful to the environment also. But using plants has ...
Scientists have sequenced the genomes of nearly 6,900 organisms, but they know the functions of only about half of the protein-coding genes thus far discovered. Now a multidisciplinary effort involving 15 scientists from ...
(Phys.org) —Synthetic biology is a science that aims to harness natural biological processes for other uses, such as in the manufacture of fuels and drugs. Now, synthetic biology researchers in the U.S. have developed a ...
In 1924, Science magazine reported on a fatal case of potato poisoning: James B. Matheney of Vandalia, Illinois, had gathered about one and a half bushels of tubers, which had turned green due to sunlight exposure. Two days ...
As a result of the variable nature of gene expression, genetically identical cells inhabiting the same environment can vary significantly in their numbers of key enzymes, which in turn results in strikingly different cellular ...
Tolerance of phosphorus limitation in plants is linked to a previously unidentified lipid family.
Cereals are grasses that produce grains, the bulk of our food supply. Carnegie's Plant Biology Department is releasing genome-wide metabolic complements of several cereals including rice, barley, sorghum, and millet. Along ...
(Phys.org) —When it comes to understanding how proteins perform their amazing cellular feats, it is often the case that the more one knows the less one realizes they know. For decades, biochemists and biophysicists have ...
