Solar cells made with bismuth vanadate achieve a surface area of 32 square meters per gram.  This compound can be paired with cheap oxides to split water molecules (and make hydrogen) with record efficiency.

Short-term geoengineering could postpone global warming, only to have it happen more quickly in the future.

Carotenoids tinge blackbird bills a deep orange, signalling fitness; birds with oranger bills are "are heavier and larger, have less blood parasites and pair with females in better condition than males with yellow bills."

Fibroblasts can extrude a tidy biological scaffold for stem-cell growth at a nanometer scale, while provoking a lower immune response than synthetic or animal-derived materials.

Higher levels of Omega-3 fatty acids in the blood correlate with stronger white matter in the brain.

By first reverting skin cells to endodermal cells instead of stem cells, researchers were able to transform them into better liver cells with true regenerative potential.

Headband cam reveals that babies spend 25% of their waking lives looking at other people's faces, 96% of which belonged to members of their own race.  By the age of 6 months, the faces of another race begin to all look the same.

Here: everything you ever wanted to know about star spiders.

Rodents are similar enough to humans to be used as laboratory models, so does a cat parasite that manipulates the behavior of rats also alter the behavior of humans (30-40% of whom are infected worldwide)?

Researchers have come within 99.8% of the theoretical limit of light absorption enhancement in solar cells, paving the way for "the next generation of high-efficiency, cost-effective and ultra-thin crystalline silicon solar cells."

European utilities, under pressure from a law requiring 20% of all energy to come from renewable sources by 2020, are importing millions of metric tons of wood pellets from the southern United States.  Burning these pellets produces less than half the emissions of fossil fuel, not counting the energy needed to ship them across the Atlantic.

Newly discovered chimpanzee populations in the Congo are thriving, outnumbering their cousins in West Africa, but bushmeat hunters, like researchers, are beginning to encroach.

Another study shows a correlation between use of acetaminophen (i.e. Tylenol) during pregnancy and the development of ADHD in children.

New process turns algae into biogas compatible with our natural gas infrastructure. "While it takes nature millions of years to transform biomass into biogas, it takes the SunCHem process less than an hour."

Among single-celled organisms like algae, programmed suicide can benefit relatives while suppressing the growth of non-relatives.

Off-shore wind turbines could significantly slow hurricane winds and decrease storm surges, all while generating electricity.

Novel aerogel made from wood and polymer could be thrown on an oil spill, absorbing nearly 100 times its own weight before being wrung out and used again.

Five-year-olds spanked by their mothers showed increased behavioral problems at age 9.  Those spanked by their fathers showed reduced vocabulary.

During a musical "conversation," a jazz musician scanned by fMRI showed activation of language and rhythmic centers in the brain, hemispheric mirrors that "perform syntactic processing for both music and speech."  At the same time, there was a marked deactivation of the angular gyrus, which is involved in interpreting the meaning of words if not their syntactic structure.

And finally if you want to be considered a great artist, it might be worth cultivating an eccentric persona in the most sincere manner possible.
