Contrary to popular belief, more healthy kids' meals were ordered after a regional restaurant chain added more healthy options to its kids' menu and removed soda and fries, researchers from ChildObesity180 at Tufts University Friedman School reported today in the journal Obesity. Including more healthy options on the menu didn't hurt overall restaurant revenue, and may have even supported growth.

Dispersal and adaptation are two fundamental evolutionary strategies available to species given an environment. Generalists, like dandelions, send their offspring far and wide. Specialists, like alpine flowers, adapt to the conditions of a particular place.

Ecologists have typically modeled these two strategies, and the selective pressures that trigger them, by holding one strategy fixed and watching how the other evolves. New research published in the journal Evolution illustrates the dramatic interplay during the co-evolution of dispersal and adaptation strategies.

We have all seen "fat bloom", that unwelcome white layer that occasionally forms on chocolate. It is harmless but Europe once banned ugly fruit so cosmetics are clearly important to them and for that reason Nestlé and the Hamburg University of Technology got the DESY synchrotron's high brilliance X-ray source PETRA III on the case.

Common DNA modifications occur through methylation, a chemical process that can dramatically change gene expression, which regulates the eventual production of proteins that carry out the functions of an organism. 

DNA encodes genetic information in its chemical bases: adenine, cytosine, guanine, and thymine. Methylated cytosine is the dominant DNA modification found in eukaryotes, a taxonomical classification that includes mammals, insects, worms, plants, and algae, but new papers have identified an adenine DNA methylation that also epigenetically regulates cellular function in green algae, worms, and flies.

On March 17th, 2013, an object the size of a boulder hit the lunar surface in Mare Imbrium and exploded in a flash of light nearly 10 times as bright as anything ever recorded before - the largest recorded explosion occurred on the surface of the moon.

A common black fungus, Aspergillus carbonarius ITEM 5010, found in decaying leaves, soil and rotting fruit has been used to to create hydrocarbons, the chief component of petroleum, similar to those in aviation fuels. The fungus produced the most hydrocarbons on a diet of oatmeal but also created them by eating wheat straw or the non-edible leftovers from corn production.

Fungi have been of interest for about a decade within biofuels production as the key producer of enzymes necessary for converting biomass to sugars. Some researchers showed that fungi could create hydrocarbons, but the research was limited to a specific fungus living within a specific tree in the rainforest, and the actual hydrocarbon concentrations were not reported.
