Submission + - Fructose Isn't Just Sugar. It Acts More Like a Hormone (scienceblog.com) 1

smazsyr writes: A new review says we've had fructose wrong for decades. The nine authors, led by Richard Johnson at the University of Colorado Anschutz, argue that fructose is not just a calorie. It is a signal. It tells the liver to make fat, hold on to water, and brace for a famine that never comes. The old story made sense for a bear fattening up on autumn berries. It makes less sense for a person drinking soda in March. The review reframes the WHO's sugar guideline. It is not really a warning about calories. It is a warning about a hormone-like molecule we have been dosing ourselves with, several times a day, for most of a century.

Submission + - Landmark Calculation Clears the Way to Answering How Matter is Formed (scienceblog.com)

smazsyr writes: "An international collaboration of scientists is reporting in landmark detail the decay process of a subatomic particle called a kaon – information that may help answer fundamental questions about how the universe began. The calculation in the study required 54 million processor hours on the IBM BlueGene/P supercomputer at Argonne National Laboratory, the equivalent of 281 days of computing with 8,000 processors. “This calculation brings us closer to answering fundamental questions about how matter formed in the early universe and why we, and everything else we observe today, are made of matter and not anti-matter,” says a co-author of the paper."
