Engineer Max Lagally and colleagues create tiny pyramids assembled from several thousand germanium atoms, perfectly shaped and uniform across the surface. The pyramid crystals can hold a single charge and represent some of the smallest materials structures ever created.
Evidence suggests that neutrinos have mass and change flavors, altering our understanding of the elusive particles. Super-Kamiokande laboratory is tracking millions of particle reactions daily to gather data, which may confirm or rule out these theories.
A University of Washington study found that patients of certified nurse-midwives used 12% fewer resources than those of physicians, with lower rates of continuous fetal monitoring and epidural anesthesia. Midwives also delivered babies with a lower Caesarean-section rate compared to obstetricians.
Researchers at Oak Ridge National Laboratory have developed 'Critters On A Chip,' a living sensor integrated circuit that detects pollutants and explosives. The bioluminescent bacteria emit a visible signal when exposed to targeted substances.
Researchers find that the unique island brogue is losing traditional features such as distinct vowel sounds and words like 'pizer' for 'porch.' The dialect's survival largely depends on the island's former isolation from the mainland. Despite its decline, linguists emphasize the importance of preserving languages and cultures.
Stanford researchers have successfully used native bacteria to reduce TCE levels in groundwater by 96-98% through in situ bioremediation. This method conserves water and reduces pumping costs, but requires hydrogen peroxide as a catalyst.
