Puru Jena PhD, from the Virginia Commonwealth University Department of Physics, has said:
- “Using an external electric field as another variable in our search for such a material will bring a hydrogen economy closer to reality.”
- “This is a paradigm shift in the approach to store hydrogen.”
- “Thus far, the efforts have been on how to modify the composition of the storage material.”
- “Here we show that an applied electric field can do the same thing as doped metal ions …”
- “More importantly, it avoids many problems associated with doping metal ions such as clustering of metal atoms, poisoning of metal ions by other gases, and a complicated synthesis process.”
- “In addition, once the electric field is removed, hydrogen desorbs, making the process reversible with fast kinetics under ambient conditions …”
- “This work will help researchers create an entirely new way to store hydrogen and find materials that are most suitable.”
- “The challenge now is to find materials that are easily polarizable under an applied electric field.”
- “This will reduce the strength of the electric field needed for efficient hydrogen storage …”

- “… agronomic values of a biochar produced from wastewater sludge through pyrolysis at a temperature of 550 degrees C.”1
- “In order to investigate and quantify effects of wastewater sludge biochar on soil quality, growth, yield and bioavailability of metals in cherry tomatoes, pot experiments were carried out in a temperature controlled environment and under four different treatments consisting of control soil, soil with biochar; soil with biochar and fertiliser, and soil with fertiliser only.”
Researchers from Graduate School of the Environment, Faculty of Science, Macquarie University, New South Wales, Australia; and NSW Department of Primary Industries, Richmond, New South Wales, Australia; have presented an article titled: “Agronomic properties of wastewater sludge biochar and bioavailability of metals in production of cherry tomato (Lycopersicon esculentum).”
The researchers from New South Wales, Australia, have also noted:
- “The soil used was chromosol and the applied wastewater sludge biochar was 10tha(-1).”
- “The results showed that the application of biochar improves the production of cherry tomatoes by 64% above the control soil conditions.”
- “The ability of biochar to increase the yield was attributed to the combined effect of increased nutrient availability (P and N) and improved soil chemical conditions upon amendment.”
- “The yield of cherry tomato production was found to be at its maximum when biochar was applied in combination with the fertiliser.”
- “Application of biochar was also found to significantly increase the soil electrical conductivity as well as phosphorus and nitrogen contents.”
- “Bioavailability of metals present in the biochar was found to be below the Australian maximum permitted concentrations for food.”

- “Rice is a starch-rich raw material that can be used for trehalose production.”1
- “It can be hydrolyzed with alpha-amylase, beta-amylase, and pullulanase to produce high-maltose content of rice saccharified solution for bioconversion of maltose into trehalose by trehalose synthase (TSase).”
- “For this purpose, an efficient enzymatic procedure has been successfully developed to simultaneously produce value-added trehalose, bioethanol, and high-protein product from rice as substrate.”
Researchers from Department of Food Science and Biotechnology, National Chung Hsing University, Taichung, Taiwan, China; Department of Medicinal Botanicals and Health Care, Dayeh University, Dacun, Changhua, Taiwan, China; and Department of Chemistry, National Chung Hsing University, Taichung, Taiwan, China; have presented an article titled: “Simultaneous Production of Trehalose, Bioethanol, and High-Protein Product from Rice by an Enzymatic Process.”
The researchers from Taichung and Changua have also noted:
- “The highest maltose yield produced from the liquefied rice starch hydrolysate was 82.4 +/- 2.8% at 50 degrees C and pH 5.0 for 21-22 h.”
- “The trehalose conversion rate can reach at least 50% at 50 degrees C and pH 5.0 for 20-24 h by a novel thermostable recombinant Picrophilus torridus trehalose synthase (PTTS).”
- “All residual sugar, except trehalose, can be fully hydrolyzed by glucoamylase into glucose for further bioethanol production.”
- “The insoluble byproduct containing high yields of protein (75.99%) and dietary fiber (14.01%) can be processed as breakfast cereal product, health food, animal forage, etc.”
- “The conversion yield of bioethanol was about 98% after 64 h of fermentation time by Saccharomyces cerevisiae without any artificial culture solution addition.”
- “Ethanol can easily be separated from trehalose by distillation with a high recovery yield and purity of crystalline trehalose of 92.5 +/- 8.7% and 92.3%, respectively.”

During a meeting with a bipartisan group of governors President Barack Obama ‘… laid out three measures that will work in concert to boost biofuels production …’
President Obama has informed:
- “… Now, I happen to believe that we should pass a comprehensive energy and climate bill.”
- “It will make clean energy the profitable kind of energy, and the decision by other nations to do this is already giving their businesses a leg up on developing clean energy jobs and technologies.”
- “But even if you disagree on the threat posed by climate change, investing in clean energy jobs and businesses is still the right thing to do for our economy.”
- “Reducing our dependence on foreign oil is still the right thing to do for our security.”
- “We can’t afford to spin our wheels while the rest of the world speeds ahead.”

- “Zearalenone (ZON) is a potent estrogenic mycotoxin produced by several Fusarium species most frequently on maize and therefore can be found in food and animal feed.”1
- “Since animal production performance is negatively affected by the presence of ZON, its detoxification in contaminated plant material or byproducts of bioethanol production would be advantageous.”
- “Microbial biotransformation into nontoxic metabolites is one promising approach.”
Researchers from Christian Doppler Laboratory for Mycotoxin Research, Department for Agrobiotechnology, University of Natural Resources and Applied Life Sciences Vienna, Tulln, Austria; Institute of Applied Synthetic Chemistry, Vienna University of Technology, Vienna, Austria; Department of Applied Genetics and Cell Biology, University of Natural Resources and Applied Life Sciences Vienna, Vienna, Austria; University of Applied Sciences Wr. Neustadt, Tulln, Austria; Biomin Research Center, Tulln, Austria; have presented an article titled: “Cleavage of zearalenone by Trichosporon mycotoxinivorans to a novel non-estrogenic metabolite.”
The researchers from Austria have also noted:
- “In this study the main transformation product of ZON formed by the yeast Trichosporon mycotoxinivorans (MTV) was identified and characterised by LC-MS/MS, LC-DAD analysis.”
- “The metabolite, named ZOM-1, was purified and its molecular formula C18H24O7 was established by time-of-flight mass spectrometry (TOF-MS) from the ions observed at m/z 351.1445 [M-H](-) and at m/z 375.1416 [M+Na](+).”
- “Employing nuclear magnetic resonance spectroscopy (NMR) the novel ZON metabolite was finally identified as (5S)-5-({2,4-dihydroxy-6-[(1E)-5-hydroxypent-1-en-1-yl]benzoyl}oxy)hexanoic acid.”
- “The structure of ZOM-1 is characterized by an opening of the macrocyclic ring of ZON at the ketone group at C6′.”
- “ZOM-1 did not show estrogenic activity in a sensitive yeast bioassay even at a thousand fold higher concentration than ZON, and did not interact with the human estrogen receptor in an in vitro competitive binding assay.”

Greg Scholes, Professor of Chemistry, from University of Toronto, in Toronto, Ontario, Canada, has said:
- “There’s been a lot of excitement and speculation that nature may be using quantum mechanical practices …”
- “Our latest experiments show that normally functioning biological systems have the capacity to use quantum mechanics in order to optimize a process as essential to their survival as photosynthesis.”
- “We stimulated the proteins with femtosecond laser pulses to mimic the absorption of sunlight …”
- “This enabled us to monitor the subsequent processes, including the movement of energy between special molecules bound in the protein, against a stop-clock.”
- “We were astonished to find clear evidence of long-lived quantum mechanical states involved in moving the energy.”
- “Our result suggests that the energy of absorbed light resides in two places at once – a quantum superposition state, or coherence – and such a state lies at the heart of quantum mechanical theory.”
- “This and other recent discoveries have captured the attention of researchers for several reasons …”
- “First, it means that quantum mechanical probability laws can prevail over the classical laws of kinetics in this complex biological system, even at normal temperatures.”
- “The energy can thereby flow efficiently by–counter intuitively–traversing several alternative paths through the antenna proteins simultaneously.”
- “It also raises some other potentially fascinating questions, such as, have these organisms developed quantum-mechanical strategies for light-harvesting to gain an evolutionary advantage?”
- “It suggests that algae knew about quantum mechanics nearly two billion years before humans …”

Henry Nguyen, Director of the National Center for Soybean Biotechnology at the MU College of Agriculture, Food and Natural Resources, has said:
- “The genome sequence will be a new tool for plant breeders, industrial engineers, geneticists, biochemists, technologists, nutritionists and anyone else who uses soybeans worldwide …”
- “With knowledge of which genes control which soybean traits, scientists may be able to better adapt the plant to drought conditions, bringing a new cash crop and food product to poor areas of the Earth.”
- “Perhaps the most exciting thing that we have found for the soybean community is the gene that confirms resistance to the devastating Asian Soybean Rust disease …”
- “In countries where this rust is well established, soybean losses can range from 10 to 80 percent. Improved soybean strains resistant to the disease will greatly benefit production and increase foodstuffs around the world.”
