Iron atoms convey mussel fibers with a robust but stretchy covering We may like to eat mussels steamed in white wine, but we also like to find mussels at the beach. Mostly they are burrowed into the ground or tethered to rocks. But if you look closer you will find a mollusc which has adapted to life and nutrition in a special and fascinating way. Mussels thrive in rocky seashore habitats, in spite of the enormous physical demands present there. This is in no small part due to the evolution of...

Scientists at the University of North Carolina at Chapel Hill School of Medicine and the University of California, San Francisco have developed and experimentally tested a technique to predict new target diseases for existing drugs. The researchers developed a computational method that compares how similar the structures of all known drugs are to the naturally occurring binding partners -- known as ligands -- of disease targets within the cell. In a study published this week in Nature, the...

How many times have you spent hours slaving over an impossible problem, only to take a break and then easily solve the problem, sometimes within minutes of looking at it again? Although this is actually a common phenomenon, up until now the way that this occurs has been unclear. But new research in the September issue of Psychological Science, a journal of the Association for Psychological Science, demonstrates the answer is more complex than simply having an "Aha!" moment. The new research,...

By Peng, J Z Yang, X Z; Zhou, F C; Gray, M F According to the average lattice and atom model of the empirical electron theory (EET) of solids and molecules, effects of interstitial impurities on valence electron structures (VESs) and phase transformation of Ti-Al alloys are analysed. In particular, melting points or allotropic transformation in Ti-Al phase diagram affected by interstitial impurities are calculated using the bond energy formula of the EET. It is demonstrated that because of...

New method 'self-assembles' metal atoms into porous nanostructures For 5,000 years the only way to shape metal has been by the "heat and beat" technique. Even with modern nanotechnology, metalworking involves carving metals with electron beams or etching them with acid. Now Cornell researchers have developed a method to self-assemble metals into complex configurations with structural details about 100 times smaller than a bacterial cell by guiding metal particles into the desired form using...

By Liang, Yong-mei Jun, Ma; Liu, Wei ABSTRACT: A laboratory study demonstrated that ferrate pretreatment significantly enhanced lead and cadmium removal in alum coagulation, under the conditions of natural surface water. The enhancement of lead removal was approximately 21 to 37% by ferrate pretreatment at a dosage of 1 to 5 mg/L. The enhanced removal of cadmium by ferrate pretreatment at a dosage of 1 to 5 mg/L exceeded the removal by alum coagulation alone 2- to 12-fold. Cadmium is much...

Do metal complexes casually stroll around certain molecules prior to chemical reactions? Scientists in the Organic Chemistry Department of the Weizmann Institute of Science have caught a glimpse of platinum-based complexes "walking" a path to their destinations. Many types of chemical reactions and new materials depend on the integration of metals with organic (carbon based) molecules. Metals, for instance, assist in transformations of chemical compounds, while materials with many kinds of...

Word of the Day
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
