Mammoth proteomics

Using high-resolution tandem mass spectometry, a set of 126 proteins procedent from a 45,000 year old mammoth bone was generated. This breaktrough widens the perspectives for the field of paleoproteomics and offers a solution for phylogenetic analysis and physiological studies for which there is no DNA information available.

Hunting the Higgs boson

The European Organization for Nuclear Research (CERN) has now data procedent from its Large Hadron Collider and the Compact Muon Solenoid that is expected to elucidate the mistery surrounding the existence of the Higgs boson.

A new method for predicting the 3D structure of a protein from its DNA coding sequence has been developed. This method relies on the information provided by the evolutionary conservation of interacting aminoacid residues. The significance of the correlation of coevolving residues and the 3D protein structure is further tested through maximum entropy statistics and the accuracy of the method is determined by comparing the predicted structures for some proteins with known structures.

A team at the MIT has developed a recording device capable of capturing the movement of  a light pulse at roughly half a trillion frames per second. This device can be used for material analysis and may also have medical applications.
