CSHL scientists identify new drug target against virulent type of breast cancer
(27 Aug 2008)
Enzyme target, Brk, is shown to be an accelerator of HER2-positive tumors
Tumor cells in a particular subset of breast cancer patients churn out too much of a protein called ErbB2 - also often called HER2 - which drives the cells to proliferate unchecked. Patients unlucky enough to be in this group - about one in ......

New Protein Survey by Scripps Research Scientists Upends Understanding of Cell Death Process
(25 Aug 2008)
Results Reveal Numerous Potential New Drug Targets for Related Diseases
Results from a Scripps Research Institute study have nearly tripled the number of proteins known to be involved in the critical process of programmed cell death, and have shot down a long-held idea about the life cycle of proteins. The work ......

That tastes -- sweet? Sour? No, it's definitely calcium!
(25 Aug 2008)
That tastes -- sweet? Sour? No, it's definitely calcium!
Chemists in Philadelphia are reporting a discovery that could expand the palate of human tastes — sweet, sour, salty, bitter, and savory — to include a new taste sensation that they term "calcium." In a report at the 236th National Meeting of ......

Carnegie Mellon MRI technology that non-invasively locates, quantifies specific cells in the body
(22 Aug 2008)
Magnetic resonance imaging (MRI) isn't just for capturing detailed images of the body's anatomy. Thanks to novel imaging reagents and technology developed by Carnegie Mellon University scientist Eric Ahrens, MRI can be used to visualize cell ......

Catalyst mystery unlocked
(20 Aug 2008)
Different keys are not supposed to fit the same lock, but in biological systems multiple versions of a catalyst all make a reaction go, according to a new study that explains the phenomenon. Scheduled for PNAS Early Edition, a study ......

New metamaterials that bend light backwards bring invisibility cloaks 1 step closer
(13 Aug 2008)
Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution ......

New synthetic route to oxindoles
(12 Aug 2008)
Peter Kündig and colleagues from Geneva University, Switzerland and Stephen Marsden and co-workers at the University of Leeds, in the UK, have developed an asymmetric Pd/N-heterocyclic carbene (NHC) - catalysed intramolecular -arylation of ......
