 Does Artificial Food Coloring Contribute to ADHD in Children? Scientific AmericanKraft Macaroni & Cheese—that favorite food of kids, packaged in the nostalgic blue box—will soon be free of yellow dye. Kraft announced Monday that it will remove artificial food coloring, notably Yellow No. 5 and Yellow No. 6 dyes, from its iconic product by January 2016. Instead, the pasta will maintain its bright yellow color by using natural ingredients: paprika, turmeric and annatto (the latter of which is derived from achiote tree seeds). Read More…

Origin of life: Chemistry of seabed’s hot vents could explain emergence of life. Science Daily

Hot vents on the seabed could have spontaneously produced the organic molecules necessary for life, according to new research. The study shows how the surfaces of mineral particles inside hydrothermal vents have similar chemical properties to enzymes, the biological molecules that govern chemical reactions in living organisms. This means that vents are able to create simple carbon-based molecules, such as methanol and formic acid, out of the dissolved CO2 in the water. Read More…

Ordering an Espresso 220 Miles Above Earth Is About to Become a Whole Lot Easier. World Science Festival.

When Drake, Milton Drake that is, penned the line, “Shoot me the pot, and I’ll pour me a shot,” never in his wildest dreams could he have had space in mind. But yesterday’s successful SpaceX launch may lend new meaning to java jive. Back in 2013 Luca Parmitano, an Italian astronaut, reportedly had one main complaint about working on the International Space Station: nary a cup of espresso to be found. Having returned to Earth after five months in space, we can safely assume he has had his espresso fix by now. But soon enough, Parmitano’s colleagues still orbiting our planet may be able to sip some java while looking down on the island nation of Java. Read More…


200-year lag between climate events in Greenland, Antarctica: Ocean involved. Science Daily

A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, giving scientists a clearer picture of the link between climate in the northern and southern hemispheres. Read More…
