The novel Natural Sciences Repository aims to provide reliable information on various areas of scientific interest and presents its content in the simplest words and terms possible. The site has now added the categories Acid Residues and Acid Sequence to its Acid section. The first new category contains scientific information on amino acid residues, which are a by-product of the peptide formation process whereas the second newly included category contains scientific information on Acid...

A more-sensitive method to analyze protein interactions has uncovered a new way that cancer cells may use the cell-surface molecule HER3 to drive tumor progression following treatment with HER1 and HER2 inhibitors. The HER family of receptors has been linked to the development of a wide variety of human cancers. HER1 inhibitors such Iressa and HER2 inhibitors such as Herceptin are commonly used in the clinic for treatment of small cell lung carcinoma and breast cancer. A recent study...

Mass spectrometry protein assays that match sensitivity and accuracy of antibody-based clinical tests might speed drug discovery, basic biology research Combining two well-established analytic techniques and adding a twist identifies proteins from blood with as much accuracy and sensitivity as the antibody-based tests used clinically, researchers report this week in Proceedings of the National Academy of Sciences Early Edition online. The technique should be able to speed up development of...

Tagish Lake Meteorites Help Solve Amino Acid Mysteries
2012-07-26 14:48:28

Lee Rannals for redOrbit.com - Your Universe Online New clues have been unveiled that shed light on why living things use only molecules with specific orientations. Research analyzing meteorite fragments that fell on a frozen lake in Canada is providing strong evidence that liquid water inside an asteroid leads to a preference of left-handed over right-handed forms of common protein amino acids in meteorites. "Our analysis of the amino acids in meteorite fragments from Tagish Lake...


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.

Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
