Switching To New Anti-bacterial Targets: Riboswitches
The recently emerged field of bacterial riboswitches may be a good hunting ground for effective targets against bacterial infection, according to a report by Yale researchers in the journal Chemistry and Biology, who showed that a riboswitch controlling vitamin B1 (thiamine) levels is disrupted in the presence of pyrithiamine, a toxic compound related to the vitamin. Kidney injury in hospital increases long-term risk of death, study fin
Patients with sudden loss of kidney function, called acute kidney injury, are more likely to die prematurely after leaving the hospital -- even if their kidney function has apparently recovered, according to new research. Napping A More Effective Countermeasure To Sleepiness In Younger Peopl
Coffee is an effective countermeasure to sleepiness for both young and middle-aged people. However, napping is more efficient in young than in middle-aged people. How OK Go's Amazing Rube Goldberg Machine Was Built
Pop band OK Go's newest video features a four-minute Rube Goldberg chain reaction that's synchronized perfectly with the music. Wired talks to one of the builders of the machine shown in the video.

In the premier open-access journal PLoS Biology, Keith Yamamoto and colleagues show that the nuclear hormone receptor nhr-49 controls two different aspects of fat metabolism, which interact to form a feedback system controlling the consumption and composition of fats in the nematode. How Can Identical Twins Be Genetically Different?
University of Michigan researchers have discovered three genes that are over-expressed in rheumatoid arthritis, or RA, that were not known to be associated with the disease before. They also found that non-genetic factors influenced the expression of these genes and that the expression patterns varied between identical twins where only one twin had RA. How did flowering plants evolve to dominate Earth?
Scientists have discovered the evolutionary step which allowed flowering plants to become the most abundant and ecologically successful group of plants on Earth. Simple Biodegradable Liquids Stop Bleeding In Seconds
