Neutrons observe vitamin B6-dependent enzyme activity useful for drug development

OAK RIDGE, Tenn., Oct. 16, 2017 – Scientists at the Department of Energy’s Oak Ridge National Laboratory have performed neutron structural analysis of a vitamin B6-dependent protein, potentially opening avenues for new antibiotics and drugs to battle diseases such as drug-resistant tuberculosis, malaria and diabetes.

 

Specifically, the team used neutron crystallography to study the location of hydrogen atoms in aspartate aminotransferase, or AAT, an enzyme vital to the metabolism of certain amino acids.

 

“We visualized the first neutron structure of a vitamin B6 enzyme that belongs to a large protein family with hundreds of members that exist in nature,” said ORNL’s Andrey Kovalevsky, a senior co-author of the study, which was published i...

Scientists detect gravitational waves from a new kind of nova, sparking a new era in astronomy

Some 130 million years ago, in a galaxy far away, the smoldering cores of two collapsed stars smashed into each other. The resulting explosion sent a burst of gamma rays streaming through space and rippled the very fabric of the universe.

 

On Aug. 17, those signals reached Earth — and sparked an astronomy revolution.

 

The distant collision created a “kilonova,” an astronomical marvel that scientists have never seen before. It was the first cosmic event in history to be witnessed via both traditional telescopes, which can observe electromagnetic radiation like gamma rays, and gravitational wave detectors, which sense the wrinkles in space-time produced by distant cataclysms. The detection, which involved thousands of researchers working at...

New research could explain how river-like channels formed on Mars

A new research paper published today could help to explain how the mysterious channels, which look like dried-up riverbeds, could have formed on the surface of Mars.

 

ISIS senior scientist Dr Alan Soper was part of the research team, and he said: “This research is particularly fascinating because it could help us to answer some of the great mysteries about life on other planets... [It] represents a very exciting step forward in the search for extra-terrestrial liquid water—and with it, life.”

Mimetic Martian water is under pressure

Researchers investigating whether liquid water could exist on Mars have provided new insight into the limits of life on the red planet.

 

A team led by Dr Lorna Dougan from the University of Leeds has analysed the structure of water in a magnesium perchlorate solution —what they refer to as "mimetic Martin water"—to better understand how the liquid could exist on the Martian surface.

 

Martian soil samples gathered by the Phoenix Lander in 2009 found calcium and powerful oxidants, including magnesium perchlorate. This fuelled speculation that perchlorate brine flows might be the cause of channelling and weathering observed on the planet's surface.

Superconductivity found in thin films of TiO2

Many of us are familiar with titanium dioxide (TiO2), a whitener commonly used in sunscreens and paints such as the white lines seen on tennis courts. Less well known are other higher titanium oxides—those with a higher number of titanium and oxygen atoms than TiO—that are now the subject of intensifying research due to their potential use in next-generation electronic devices.

 

Now, researchers at Tokyo Tech have reported superconductivity in two kinds of higher titanium oxides prepared in the form of ultrathin films. With a thickness of around 120 nanometers, these materials reveal properties that are only just beginning to be explored.

 

"We succeeded in growing thin films of Ti4O7 and γ-Ti3O5 for the first time," says Kohei Yoshimatsu,...

The past, present and future of inelastic neutron scattering

Emma Cooper

The use of electron-volt neutron spectroscopy in materials research is a growing area of neutron science, capitalizing upon the unique insights provided by epithermal neutrons on the behaviour and properties of an increasing number of complex materials.

​Professor Carla Andreani, recipient of the 2016 Giuseppe Occhialini Medal and Prize for her “outstanding contributions to novel experimental techniques and methods in neutron spectroscopy and her tireless commitment to fostering the British–Italian collaboration in neutron science" has published two reviews in Advances in Physics, which capture the rapid progress in the field.

Neutrinos on nuclei

Detailed modelling of the way neutrinos interact with nuclei is crucial if DUNE and other long-baseline neutrino experiments are to extract essential neutrino properties.

A major focus of experiments at the Large Hadron Collider (LHC) is to search for new phenomena that cannot be explained by the Standard Model of particle physics. In addition to sophisticated analysis routines, this requires detailed measurements of particle tracks and energy deposits produced in large detectors by the LHC’s proton–proton collisions and, in particular, precise knowledge of the collision energy. The LHC’s counter-rotating proton beams each carry an energy of 6.5 TeV and this quantity is known to a precision of about 0.1 per cent – a feat that requires...

Canada’s neutron scientists lament closure of world’s oldest nuclear reactor

The world’s oldest operating nuclear reactor is in the twilight of its life, but the scientists who rely on it for their research are not going gentle into that good night. Canadian scientists are upset about the imminent closure of the Chalk River research reactor and are lobbying the government for a CA$200 million ($162 million) commitment so they can continue to perform materials research using the neutron beams that research reactors provide.

Neutrons provide a novel picture of thermal conductivity in complex materials

A multi-partner study published today in Nature Communications has addressed phonon lifetime measurement challenges using inelastic neutron scattering (INS) and neutron resonant spin-echo (NRSE) experiments conducted at the Institut Laue Langevin (ILL) in Grenoble, and Laboratoire Léon Brillouin (LLB) Saclay, France. Whereas the "glass-like" thermal conductivity of the clathrate Ba7.81Ge40.67Au5.33 has frequently been associated with a short phonon lifetime, this study measured for the first time to date a very long phonon lifetime using a large single crystal sample of high quality. The study also reveals a dramatic reduction of the number of phonons carrying heat, as a result of structural complexity, allowing a simple and general...

World’s smallest neutrino detector finds big physics fingerprint

OAK RIDGE, Tenn.—After more than a year of operation at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.

The research, performed at ORNL’s Spallation Neutron Source (SNS) and published in the journal Science, provides compelling evidence for a neutrino interaction process predicted by theorists 43 years ago, but never seen.

Neutrons Help To Remove Barriers Standing In The Way Of Safer, Better Batteries For Electric Vehicles

After using neutron beams to better understand materials required for safer energy storage, University of Calgary chemists and their international collaborators were able to demonstrate a prototype battery that showed major improvements to performance.

Electric vehicles promise to revolutionize transportation—but safer, better-performing batteries must first be developed before this potential can be turned into a reality. One of the primary challenges is to find a less hazardous electrolyte material for the batteries used in ‘green’ cars. Indeed, the lithium-ion batteries used in today’s electric and plug‑in hybrid vehicles (as well as in portable electronic devices) typically contain flammable liquids as their electrolyte; as such, faulty...

Iron secrets behind superconductors unlocked

SUPERCONDUCTORS: Due to magnetism iron should - theoretically - be a poor superconductor. Nevertheless certain ironbased materials possess fine superconducting properties. Why? Because the five unbound electrons found in iron - as a result of individual modes of operation, it turns out - facilitate superconductivity. This new, long sought-for explanation - appearing in this weeks issue of Science - is the result of international co-operation between experts from the Niels Bohr Institute (NBI) i Copenhagen, Denmark, and colleagues from a number of other scientific institutions in Europa and USA.

Research with Neutrons Opens New Paths to Predict Behaviour of Local Anesthetics

Determining the characteristics or effect of drugs in pure form is considered a routine calculation. What is less known is the behaviour of drugs formulated into delivery systems, which can potentially alter their chemical potency or toxicity.

With the help of two neutron instruments at the Institute Laue-Langevin (ILL) in Grenoble, France, researchers recently took a deeper look into the dynamics and mobility of drugs when combined with soluble compounds. It is an important step to further understanding the mechanisms of drug efficacy, an underlying challenge for developing safe and reliable pharmaceuticals.

Capturing 3D Water Flow in Rooted Soil by Ultra-fast Neutron Tomography

Non-invasive imaging techniques are the key for better understanding the root-soil interaction which is of great relevance for both plant and soil scientists. Neutrons are a unique probe for non-destructive investigation of root-soil systems.

We demonstrated the ability of ultra-fast tomography to quantitatively image quick changes of water content in the rhizosphere and outlined the value of such imaging data for 3D water uptake modelling. The presented method paves the way for time-resolved studies of various 3D flow and transport phenomena in porous systems.
