Ancient chemical bond may aid cancer therapy

A chemical bond discovered by Vanderbilt University scientists that is essential for animal life and which hastened the "dawn of the animal kingdom" could lead to new therapies for cancer and other diseases.

Researchers create accurate computer model of RNA tetraloop

A computational model developed by researchers at Rensselaer Polytechnic Institute is the first to accurately simulate the complex twists of a short sequence of RNA as it folds into a critical hairpin structure known as a ...

Study offers insight into the origin of the genetic code

An analysis of enzymes that load amino acids onto transfer RNAs—an operation at the heart of protein translation—offers new insights into the evolutionary origins of the modern genetic code, researchers report. Their ...

New forensic technique for analysing lipstick traces

(Phys.org) —A study by forensic scientists at the University of Kent has established a new way of identifying which brand of lipstick someone was wearing at a crime scene without removing the evidence from its bag, thereby ...

Binding together repelling atoms

Basic chemistry tells us that a bond between atoms can form if it is energetically more favorable for the atoms to stick together than staying apart. This fundamentally requires an attractive force between the atoms. However, ...

Watching catalysts at work—at the atomic scale

Scientists of Helmholtz-Zentrum Berlin (HZB) and collaborators have now combined the spectroscopic method "RIXS" with so-called ab initio theory in order to describe these processes in detail for a model organometallic catalyst ...

An unlikely competitor for diamond as the best thermal conductor

An unlikely material, cubic boron arsenide, could deliver an extraordinarily high thermal conductivity – on par with the industry standard set by costly diamond – researchers report in the current issue of the journal ...

The quantum secret to alcohol reactions in space

Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.
