Amazingly Vivid Dino Illustrations Reveal a Brutal Prehistoric World - Over its lifetime, Earth has hosted countless species. But some of those species, like the dinosaurs, have managed to claw their way into a special place in our imaginations. Now, a new book illustrates the dinosaurs — and many of the beasts of millennia ago — in beautiful, spectacular and vicious style. In one illustration, tiny Utahraptors tear at the flesh of a much larger creature. Another shows a rather unlikely but fanciful encounter between giant megalodon and funny-looking platybelodon. A more serene image depicts a well-camouflaged little dinosaur sleeping beneath a tree in a lush, green forest.

Graphene ‘wonder material’ made with kitchen blender
-
Scientists have outlined how they managed to make the “wonder material” graphene using a kitchen blender. Graphene is thin, strong, flexible and electrically conductive, and has the potential to transform electronics as well as other technologies. An Irish-UK team poured graphite powder (used in pencil leads) into a blender, then added water and dishwashing liquid, mixing at high speed. The results are reported in the journal Nature Materials. Because of its potential uses in industry, a number of researchers have been searching for ways to make defect-free graphene in large amounts. The material comprises a one-atom-thick sheet of carbon atoms arranged in a honeycomb structure. Graphite - mixed with clay to produce the lead in pencils - is effectively made up of many layers of graphene stacked on top of one another. Jonathan Coleman from Trinity College Dublin and colleagues tested out a variety of laboratory mixers as well as kitchen blenders as potential tools for manufacturing the wonder material.

Chili peppers first cultivated in Mexico

University of California, Davis

The domesticated chili pepper—the world’s most widely grown spice crop—got its start in central-east Mexico, report researchers. Results from the four-pronged investigation—based on linguistic and ecological evidence as well as the more traditional archaeological and genetic data—suggest a regional, rather than a geographically specific, birthplace for the domesticated chili pepper. That region, extending from southern Puebla and northern Oaxaca to southeastern Veracruz, is further south than was previously thought, the researchers find. The region also is different from areas of origin that have been suggested for common bean and corn, which were presumably domesticated in Western Mexico. The findings will appear in the Proceedings of the National Academy of Sciences, as part of a series of research papers on plant and animal domestication.

Sexual Healing: Bonobos Use Sex to De-Stress
-
Bonobos have earned a reputation as a “sexy” ape. Sexual activity — in many creative forms — plays a large role in bonobo society. Sexual contacts occur often, in virtually all partner combinations and in a slew of different positions. Bonobo society is also known to be more egalitarian and peaceful, especially compared with their close relatives, chimpanzees. However, conflicts still arise in bonobo groups. Zanna Clay and Frans de Waal of Emory University are studying how bonobos use sex after conflicts. I recently asked Zanna about watching bonobos and interpreting the role of sex in making up.
