When most people think 'green' in America, they think of liberal Democrats. It's a carefully crafted image. Conservatives who deny global warming conserve energy just as much as liberals who accept it but that gets little attention. Sociologists in a new paper instead found that the idea of the 'green' Christian is the environmental trope they need to spend their time debunking.

Researchers have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy source - 1,000 times thinner than a sheet of paper.

 Liangbing Hu, Teng Li and colleagues note that today’s batteries often use stiff, non-flexible substrates, which are too rigid to release the stress that occurs as ions flow through the battery. They knew that wood fibers from trees are supple and naturally designed to hold mineral-rich water, similar to the electrolyte in batteries. They decided to explore use of wood as the base of an experimental sodium-ion battery. Using sodium rather than lithium would make the device environmentally friendly.

Who ever guessed that sugar could be the downfall of the Bubonic Plague?

Diagnosing the presence of Yersinia pestis, the cause of the zoonotic disease also called the Black Death, may soon be much faster thanks to a simple, inexpensive and reliable glycomics  method of detecting the bacterium. 

Over 2,000 years ago, gold- and silversmiths developed a variety of techniques, including using mercury like a glue to apply thin films of metals to statues and other objects.

They developed thin-film coating technology that is unrivaled by today's process for producing DVDs, solar cells, electronic devices and other products and used it on jewels, statues, amulets and more common objects. Workmen over 2000 years ago managed to make precious metal coatings as thin and adherent as possible, which not only saved expensive metals but improved resistance to wear caused from continued use and circulation.

Understanding these sophisticated metal-plating techniques from ancient times could help preserve priceless artistic and other treasures from the past.

A new study by astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered columns of cold, dense gas exiting the disk of nearby starburst galaxy NGC 253, also known as the Silver Dollar Galaxy.

NGC 253 is located 11.5 million light-years away in the constellation Sculptor. The galaxy, with its slightly askew orientation, offers astronomers an uncommonly clear view of several super star clusters near its center. These clusters denote areas where new stars are forming and they also mark the starting point for material being ejected from the galaxy.

The pharmaceutical treatment of disease has obviously improved a lot in 50 years but that doesn't mean kids like the taste of medicine.

Does that mean kids won't take it?

Perhaps they won't take it, if you are the worst parent ever, but a review in Clinical Therapeutics takes the issues out of folklore and highlights recent advances in the scientific understanding of bitter taste, with special attention to the sensory world of children. 

Today I received news of an interesting measurement of angular distributions of the decay products in the rare decay of the B meson to  a K* and a muon pair - one of the specialties of the LHCb collaboration, which has more horse-power in some of these low-energy measurements than ATLAS and CMS.

Scientists using tracking data from Garwood Valley in the McMurdo Dry Valleys region of Antarctica have documented an acceleration in the melt rate of permafrost - ground ice - in a section of Antarctica where the ice had been considered stable.

The melt rates are comparable with the Arctic, where accelerated melting of permafrost has become a regularly recurring phenomenon, and the change could offer a preview of melting permafrost in other parts of a warming Antarctic continent, says Joseph Levy, a research associate at The University of Texas at Austin's Institute for Geophysics.

For almost a century, science has been engaged in a quest to study brain waves and learn about mental health and the way we think.

It hasn't been easy. The way billions of interconnected neurons work together to produce brain waves remains unknown. Researchers from École Polytechnique Fédérale de Lausanne's Blue Brain Project in Switzerland and the Allen Institute for Brain Science in the United States say that their numerical model is providing a new tool to solve the mystery.

Regular marijuana use in adolescence may permanently impair brain function, cognition and increase the risk of developing serious psychiatric disorders such as schizophrenia, according to a recent study in Neuropsychopharmacology.
