Achieving top grades in science subjects more difficult, proves research
Schoolchildren studying science and technology subjects like Maths, Physics and Chemistry find it much harder to achieve the top exam grades than candidates of similar ability studying subjects like Media Studies and Psychology, proves a new report. (2008-07-01)
Metals Shape Up with a Little Help from Friends
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. (2008-07-01)
Do the hyper-coordinate planar transition metal atoms exist?
A study reported in Vol 51, Issue 7 (July, 2008) of Science in China Series B: Chemistry has shown that wheel-shaped structures with octa- and enneacoordinate planar cobalt, iron and nickel centered in perfect octagonal and enneagonal boron rings, are stable on corresponding potential hyper-surfaces. This suggests that the central element bonding capacities have not been exhausted. (2008-07-01)
Tethered Molecules Act as Light-Driven Reversible Nanoswitches
The ability to see is based on molecules in the eye that flip from one conformation to another when exposed to visible light. (2008-06-24)
Could new discovery about a shape-shifting protein lead to a mighty 'morpheein' bacteria fighter?
A small molecule that locks an essential enzyme in an inactive form could one day form the basis of a new class of unbeatable, species-specific antibiotics, according to researchers at Fox Chase Cancer Center. (2008-06-23)
Gene-expression profiling of the effects of liver toxins
Gene-expression data from liver tissue or whole blood can be used to classify histopathologic differences in the effects of hepatotoxins. It is hoped that these findings, published in BioMed Central's open access journal, Genome Biology, will lead to a more precise way of defining the potential hepatotoxicity of new compounds. (2008-06-20)
Researchers confirm benzene-like electron delocalization of important molecule
Researchers in the lab of University of Oregon chemist Shih-Yuan Liu have successfully synthesized and structurally characterized boron-nitrogen compounds that are isoelectronic and isostructural to the fundamentally important benzene molecule. (2008-06-20)
MIT researchers see alternative to common colorectal cancer drug
A compound that accumulates in cells more readily than a commonly used colorectal cancer drug may be just as useful in treating colorectal tumors, but with fewer side effects, MIT researchers have found. (2008-06-18)
Secret ingredient: nanoparticles aid bone growth
In the first study of its kind, bioengineers and bioscientists at Rice University and Radboud University in Nijmegen, Netherlands, have shown they can grow denser bone tissue by sprinkling stick-like nanoparticles throughout the porous material used to pattern the bone. (2008-06-16)
Computer models show major climate shift as a result of closing ozone hole
A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate. (2008-06-13)
