Most medications prescribed in primary care contain animal derived products.

Are they suitable for vegetarians?

Dietary preferences are common in the general population. Influences such as religion, culture, economic status, environmental concern and personal preferences all play a part in the foods that people choose to consume. Most doctors are unaware that commonly prescribed drugs contain animal products and would be surprised that it matters. But most patients are not aware either and if they have a dietary preference it might impact the medicines they are willing to take also. 

The nature of social science is that you will frequently find papers arguing contradictory positions, and nothing shows that like video games. On Science 2.0 alone, you can find dozens of studies arguing both sides.

Mirjana Bajovic of Brock University quizzed a group of eighth-graders (aged 13–14) about their playing habits and patterns and determined their stage of moral reasoning using an established scale of one to four. The goal was to determine if there was a link between the types of video games teens played, how long they played them, and the teens’ levels of moral reasoning: their ability to take the perspective of others into account. 

Lorena Moscardelli of Statoil North America–Research, Development and Innovation in Austin is not the first to claim evidence to support the existence of a Martian ocean during the late Hesperian–early Amazonian. Viking Orbiter images did that throughout the 1980s and early 1990s.

Others have based their beliefs on alleged paleoshorelines, which has been heavily contested due to large variations in elevation (and some turned out to be of volcanic origin), but Moscardelli uses a new terrestrial, deep-water analogy. 

The increasing use of chemical herbicides, both synthetic and organic kinds, is often blamed for the declining plant biodiversity in farms, but it is simplistic to think herbicide exposure is solely to blame.

The science doesn't add up. If herbicides are a key factor in declining diversity, then thriving species would be more tolerant to widely used herbicides than rare or declining species, according to J. Franklin Egan, research ecologist, USDA-Agricultural Research Service. But that isn't the case.

Almost one-third of US adolescents consume high-caffeine energy drinks and the teens who do also report higher rates of alcohol, cigarette, or drug use, according to a paper in the Journal of Addiction Medicine.

The same characteristics that attract young people to consume energy drinks—such as being "sensation-seeking or risk-oriented" — may make them more likely to use other substances as well, suggests the new paper by Yvonne M. Terry-McElrath, MSA, and colleagues of the Institute for Social Research, University of Michigan, Ann Arbor. 

For decades, scientists have been pushing toward the goal of creating artificial building blocks that can self-assemble in large numbers and reassemble to take on new tasks or to remedy defects. Researchers from the University of Southern Denmark have taken a step toward that.

"The potential of such new man-made systems is almost limitless, and many expect these novel materials to become the foundation of future technologies," says Dr. Maik Hadorn from Department of Chemistry and Applied Biosciences at ETH Zürich. "We used short DNA strands as smart glue to link preliminary stages of artificial cells (called artificial vesicles) to engineer novel tissue-like structures."
