Probing a geological question on Mars: What is the correct price for a robotic scientific mission to another planet?

NASA’s upcoming Insight’s mission is a lander designed to probe the seismic environment of Mars. Equipped with a seismometer, the mission’s main scientific objectives is to understand the geological activity of present day Mars, a goal that is on the one side, controversial, but on the other, useful and with an expensive price tag.   … More Probing a geological question on Mars: What is the correct price for a robotic scientific mission to another planet?

Elucidating molecular processes of molecules in dilute solutions with X-ray free electron laser spectroscopy

With diffraction quality crystals a rarity and some compounds and proteins almost impossible to crystallize, or in a crystal form without ligand in binding cavity, structural biology is often thought of as a field for the most patient. Why? Notwithstanding whether a particular target protein would form crystals of quality sufficient for structural elucidation, some … More Elucidating molecular processes of molecules in dilute solutions with X-ray free electron laser spectroscopy

Post antibiotic treatment expansion of pathogenic gut microbes induced by availability of oxidised sugars

Antibiotic resistance is frequently publicized in the popular media such as television advertisement and newspapers and has helped inform the general public about the perils of not completing a course of antibiotic treatment. Briefly, antibiotic resistance arises when a subpopulation of microorganisms developed resistance to antibiotic treatment either through reducing their metabolic rate (e.g., persistence … More Post antibiotic treatment expansion of pathogenic gut microbes induced by availability of oxidised sugars

Importance of theory and simulation in laying the case for building large colliders for multinational particle physics experiments

Higgs boson was discovered at the Large Hadron Collider located at the border between Switzerland and France, which delivered the most important theoretical validation underlying the basis for the funding and construction of the collider itself. Fitting in at the 125 GeV (eV: electronvolt) void in the Standard Model for Particle Physics, the search for … More Importance of theory and simulation in laying the case for building large colliders for multinational particle physics experiments

Atomic force microscopy on a high speed spacecraft orbiting a comet

A short post to highlight the presence of an atomic force microscopy instrument onboard a high speed spacecraft that orbited a comet that yielded science data reported in a journal. The spacecraft, Rosetta, sampled comet dust particles from comet 67P/Churyumov-Gerasimenko and analysed it first with a Comet Secondary Ion Mass Analyzer (COSIMA), followed by an … More Atomic force microscopy on a high speed spacecraft orbiting a comet
