While enthusiasts across the world pored over the Voynich manuscript, penned by an unknown author in a language no one understands, a research team at the University of Arizona solved one of its biggest mysteries: When was the book made? University of Arizona researchers have cracked one of the puzzles surrounding what has been called "the world's most mysterious manuscript" "“ the Voynich manuscript, a book filled with drawings and writings nobody has been able to make sense of to this...

AKRON, Ohio, Jan. 7, 2011 /PRNewswire/ -- A number of new ventures, funded with millions of dollars by large oil companies and major investors, are growing algae to produce biodiesel, jet fuel and other biofuels. Many of these processes use fossil fuel carbon dioxide (CO2) to "feed" their photosynthetic algae, which as a side effect could help reduce global warming. But a potentially greater advantage from using fossil fuel CO2 to grow algae is that it can create a wide variety of safer,...

AKRON, Ohio, Jan. 4, 2011 /PRNewswire/ -- A new method of child and maternal nutrition could prevent a specific type of genetic damage that would otherwise occur in up to 160 million brain cells in each person over their lifetime. Preventing this genetic damage could have significant implications related to aging and cancer. Most people are unaware that every type of food currently eaten is measurably contaminated with a radioactive material from the air known as carbon-14, or radiocarbon....

Researchers from around the world compile more reliable data that will help science and industry For the first time in history, a change will be made to the atomic weights of some elements listed on the Periodic table of the chemical elements posted on walls of chemistry classrooms and on the inside covers of chemistry textbooks worldwide. The new table, outlined in a report released this month, will express atomic weights of 10 elements - hydrogen, lithium, boron, carbon, nitrogen, oxygen,...

Researchers have found compelling evidence for an extensive biological community living in porous rock deep beneath the seafloor. The microbes in this hidden world appear to be an important source of dissolved organic matter in deep ocean water, a finding that could dramatically change ideas about the ocean carbon cycle. Matthew McCarthy, associate professor of ocean sciences at the University of California, Santa Cruz, led a team of researchers from several institutions who analyzed the...

Innovative research technique reveals C4 grasses older than previously thought A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought. This new evidence casts doubt on the widely-held belief that the rise of this incredibly productive group of plants was driven by a large drop in atmospheric carbon dioxide concentrations during the Oligocene epoch. The...

Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Scientists from the National Institute of Standards and Technology (NIST), working with researchers from Purdue University, the University of Tennessee, Oak Ridge National Laboratory and Wabash College, tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay...

Radiocarbon dating is used to determine the age of everything from ancient artifacts to prehistoric corals on the ocean bottom. But in a recent study appearing in the Aug. 26 edition of the journal, Nature, a Lawrence Livermore scientist and his colleagues used the method to trace the pathway of carbon dioxide released from the deep ocean to the atmosphere at the end of the last ice age.The team noticed that a rapid increase in atmospheric CO2 concentrations coincided with a reduced amount of...

Relevance for geo-engineers: What fizzed once, can fizz again Imagine loosening the screw-top of a soda bottle and hearing the carbon dioxide begin to escape. Then imagine taking the cap off quickly, and seeing the beverage foam and fizz out of the bottle. Then, imagine the pressure equalizing and the beverage being ready to drink. Rutgers marine scientist Elisabeth Sikes and her colleagues say that something very similar happened on a grand scale over a 1,000 year period after the end of the...

Rice study: Human activity eclipses Brazos River's native carbon cycle A new study by geochemists at Rice University finds that damming and other human activity has completely obscured the natural carbon dioxide cycle in Texas' longest river, the Brazos. "The natural factors that influence carbon dioxide cycling in the Brazos are fairly obvious, and we expected the radiocarbon signature of the river to reflect those influences," said study co-author Caroline Masiello, assistant professor of...
