Biologists at the University of California, San Diego have found another member in a new class of cellular motor proteins that rewind and seal together sections of the double-stranded DNA molecule that occasionally but perilously become unwound. Their discovery, which provides a promising new avenue for the development of drugs that kill cancer cells, is detailed in a paper published in this week's early online edition of the Proceedings of the National Academy of Sciences. The same...

The nature-nurture debate is a "giant step" closer to being resolved after scientists studying bees documented how environmental inputs can modify our genetic hardware. The researchers uncovered extensive molecular differences in the brains of worker bees and queen bees which develop along very different paths when put on different diets The research was led by Professor Ryszard Maleszka of The Australian National University's College of Medicine, Biology and Environment, working with...

Researchers at New York University's Courant Institute of Mathematical Sciences have developed a novel algebraic model of DNA "hybridization," a process central to most biotechnology devices that monitor changes in cell's gene expression or characterize a cell's genome. Their work, which is described in the journal Physical Review E, provides an additional tool for understanding how biological systems function and could enhance methods and designs of technologies used in cancer and genetics...

By Matt Shipman, North Carolina State University Researchers from North Carolina State University have found a way to optimize the development of DNA self-assembling materials, which hold promise for technologies ranging from drug delivery to molecular sensors. The key to the advance is the discovery of the "Goldilocks" length for DNA strands used in self-assembly "“ not too long, not too short, but just right. DNA strands contain genetic coding that will form bonds with another strand...

The Cold Triple Axis spectrometer, a new addition to Oak Ridge National Laboratory's High Flux Isotope Reactor and a complementary tool to other neutron scattering instruments at ORNL, has entered its commissioning phase. The CTAX uses "cold" neutrons from the HFIR cold source to study low-energy magnetic excitations in materials. Cold neutrons are slower than their "thermal" neutron counterparts, and thus perfect for probing low-energy dynamics. The instrument, which moves by way of air pads...

Polymer-based photovoltaic cells have some real advantages compared to the currently used semiconductor-based cells. They are easy to make and the materials are cheap. The challenge is to figure out how to make efficient cells while keeping the manufacturing cost low. One approach uses a light-absorbing polymer along with a derivative of a sixty-carbon fullerene molecule, commonly known as a buckyball. For maximum efficiency, the two materials must be present in thin layers near opposite...

Sky
2004-10-19 04:45:44

Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The blue colour of the daytime sky results from the selective scattering of light rays. When the sunlight...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
