Novel enzyme from tiny gribble could prove a boon for biofuels research - June 18th

Researchers from the United Kingdom, the Energy Department’s National Renewable Energy Laboratory (NREL), and the University of Kentucky have recently published a paper describing a novel cellulose-degrading enzyme from a marine wood borer Limnoria quadripunctata, commonly known as the gribble. Gribbles are biologically intriguing because they exhibit a relatively unique ability to produce their own enzymes instead of using symbiotic microbes to break down the biomass they eat. New biomass-degrading enzymes from novel sources such as the gribble may prove beneficial to the biofuels industry. Read more

Bio-nanocomposites need improvement to match conventional packaging, says research - June 27th

Bio-nanocomposite packaging materials have a bright future but are not yet at the level of petroleum-based plastics, according to a review article. Bio-nanocomposite materials with added functional properties have potential for the development of technologies such as active and intelligent packaging, high barrier packaging, nanosensors, freshness indicator, self-cleaning, and nanocoating. However, the present level of improvements is not enough to compete with petroleum-based plastics, the authors noted in the Progress in Polymer Science journal. Read more

Diet drinks are not the sweet solution to fight obesity, health problems - July 11th

Diet beverages and other non-caloric, artificially sweetened foods and drinks may not be the healthy choice to manage weight that they appear, according to a Purdue University expert’s review of recent scientific studies. Swithers, who studies ingestive behavior and body weight -specifically the roles that artificial sweeteners and other food substitutes play in weight management and eating - reviewed and evaluated the most recent research on whether consuming high-intensity sweeteners, despite their zero or low calories, may result in overeating, weight gain or other health problems.

Improving Crop Yields in a World of Extreme Weather Events - July 1st

8 When plants encounter drought, they naturally produce abscisic acid (ABA), a stress hormone that helps them cope with the drought conditions. Specifically, the hormone turns on receptors in the plants. Botanists have identified an inexpensive synthetic chemical, quinabactin, that mimics ABA. Spraying ABA on plants improves their water use and stress tolerance, but the procedure is expensive. Quinabactin now offers a cheaper solution. Read more

Bisphenol A directly absorbed through sublingual exposure - June 27th

For the first time, a team from INRA and the French École Nationale Vétérinaire de Toulouse has shown that Bisphenol A (BPA) can be directly absorbed through the mouth. This entry route leads to BPA levels in the blood which are about 100 times higher than when the same amount is absorbed from the gastro-intestinal tract. If this permeability is confirmed in humans, BPA could enter the body directly through the oral mucosa. This would represent a direct route to the bloodstream that has been used for certain medications to bypass the protective action of the liver. Read more

Hydrogen technologies : new process uses enzymes as catalysts - June 26th
For the first time, a research team from the CEA1, Collège de France, CNRS and Université Joseph Fourier in Grenoble has developed an efficient process for in vitro activation of an enzyme, hydrogenase, which is found in microorganisms that use hydrogen as a source of energy. This was made possible by combining approaches from biomimetic and protein chemistry. The results will lead to use of the wide variety of hydrogenase enzymes found in nature, and even the possibility of ’invented’ artificial enzymes over the long term, which may potentially serve as catalysts for fuel cells or the production of hydrogen from sources of renewable energy.
