Hebrew University, US scientists find clue to mystery of how biological clock operates on 24-hour cycle
Human as well as most living organisms on earth possess circadian a (24-hour) life rhythm. This rhythm is generated from an internal clock that is located in the brain and regulates many bodily functi...

The research, which appears in the Nov. 23 online edition of the journal Proceedings of the National Academy of Science, explores how peptides interact with mineral surfaces by accelerating, switching...
Life Sciences | Read moreNew Cancer Target for Non-Hodgkin's Lymphoma
Promising results have led to the design of a clinical trial that will soon be under way to test a compound -- called PU-H71 -- in human patients. This compound is in a new class of drugs, called heat...
Life Sciences | Read moreComputational microscope peers into the working ribosome
The first study, in Proceedings of the National Academy of Sciences, concerns the intimate signaling between the ribosome and an elongation factor (EF-Tu) that is essential to the successful assembly ...
Studies and Analyses | Read moreNew hydrogen-storage method discovered
The discovery paves the way for an entirely new way to approach the hydrogen-storage problem. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen (H2) ...

Physician-scientists from Weill Cornell Medical College have discovered a molecular mechanism that may prove to be a powerful target for the treatment of non-Hodgkin's lymphoma, a type of cancer ...
Life Sciences | Read moreTiny Bubbles Clean Oil from Water
Now, a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil...
Life Sciences | Read moreNew paper describes connections between Circadian and metabolic systems
The relationship between circadian and metabolic systems the researchers describe could have important implications for understanding the higher incidence of cardiovascular disease, obesity and diabet...
Life Sciences | Read moreVibrations key to efficiency of green fluorescent protein
University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel P...
Life Sciences | Read morePTB Terahertz calibration satisfies US laser manufacturer
Terahertz radiation still lies in a metrological no man's land – a metrology gap. The Physikalisch-Technische Bundesanstalt (PTB) can now close this gap. For the first time, a commercial Terahert...
Process Engineering | Read moreNew Notre Dame study provides insights into the molecular basis of tumor cell behavior
The study elucidates mechanisms involved in the release of microvesicles –small membrane enclosed sacs– from tumor cells that facilitate creation of paths of least resistance allowing tumor cells to m...
Life Sciences | Read moreHybrid Molecules Show Promise for Exploring, Treating Alzheimer's
In order to answer that key question and develop new approaches to preventing the damage, scientists must first understand how amyloid-beta forms the telltale clumps.University of Michigan res...
