MRI scanning assists with next generation battery design
Magnetic resonance imaging (MRI) can provide an effective way of supporting the development of the next generation of high-performance rechargeable batteries, according to research led by the University of Birmingham. The technique, which was developed to detect the movement and deposition of sodium metal ions within a sodium battery, will enable faster evaluation of new battery materials, and help to accelerate this type of battery's route to market.

Molecular and isotopic evidence for milk, meat, and plants in prehistoric eastern African herder food systems
The development of pastoralism is known to have transformed human diets and societies in grasslands worldwide. Cattle-herding has been (and still is) the dominant way of life across the vast East African grasslands for thousands of years. This is indicated by numerous large and highly fragmentary animal bone assemblages found at archaeological sites across the region, which demonstrate the importance of cattle, sheep and goat to these ancient people.

’Freeze frame’ chemistry to unlock drugs of the future
Researchers are taking snapshots of chemical reactions in a trillionth of a second in the hope of developing the next generation of antibiotics and anti-viral drugs. Using state-of-the-art laser technology, scientists at Cardiff University and the Rosalind Franklin Institute are creating 'freeze frame movies' of chemical reactions, with a starring role for a specific enzyme that could be used to make new drugs that are active against viruses, such as COVID-19.

Common treatments used on cattle have devastating impacts on wildlife
Experts have stressed an urgent need to find alternatives to wormers and anti-ectoparasitic products used widely on cattle, following the findings of a study just published in Environmental Toxicology and Chemistry. Researchers from the University of Sussex looked at a body of published evidence into the environmental impact of anthelmintics — products used as wormers and anti-parasitic agents and widely applied across the world.

Bristol pioneers use of VR for designing new drugs
The findings, published in the journal PLOS One describe how researchers used VR to understand how common medications work on a molecular level. Many drugs are small molecules, and discovering new drugs involves finding molecules that bind to biological targets like proteins. In the study, users were able to use VR to 'step inside' proteins and manipulate them, and the drugs binding to them, in atomic detail, using interactive molecular dynamics simulations in VR (iMD-VR).

EPSRC New Investigator Award 2020 for research on protocellular materials
Dr Pierangelo Gobbo said: "Currently, the research field of bottom-up synthetic biology is trying to fill the gap between biology and chemistry to better understand how the non-living becomes alive. To do this, attempts have been made to construct what are called protocells. These are cell-like entities created from scratch using only a limited toolbox of molecules, materials, and chemical reactions.

New tools show a way forward for large-scale storage of renewable energy
A technique based on the principles of MRI and NMR has allowed researchers to observe not only how next-generation batteries for large-scale energy storage work, but also how they fail, which will assist in the development of strategies to extend battery lifetimes in support of the transition to a zero-carbon future.

Fast-charging, long-running, bendy energy storage breakthrough
A new bendable supercapacitor made from graphene, which charges quickly and safely stores a record-high level of energy for use over a long period, has been developed and demonstrated by UCL and Chinese Academy of Sciences researchers. While at the proof-of-concept stage, it shows enormous potential as a portable power supply in several practical applications including electric vehicles, phones and wearable technology.

Smart design of new materials could improve energy storage technologies
Materials that can be precisely designed at the nanoscale could allow 'supercapacitors' to store more energy while maintaining their fast charge time. Researchers from the Huazhong University of Science and Technology, Imperial College London and the Massachusetts Institute of Technology performed simulations and experiments that show special electrode materials could be precisely engineered to produce supercapacitors that charge quickly and store more energy.

Scientists uncover molecular ’first responder’ that triggers heart-attacking causing plaques
Oxford University scientist have discovered the molecular 'first responder' which detects disturbances in the flow of blood through the arteries, and responds by encouraging the formation of plaques which can lead to serious problems, including heart attack, stroke and even death. The study, published in the journal Nature , found that mice without this molecule in its right shape don't have clogged arteries, even when they eat an unhealthy high fat diet.

Accelerated speed of discovery could lead to more effective smoking cessation aids
As smokers know all too well, nicotine is highly addictive. It's hard to quit smoking, a habit that claims the lives of more than seven million people each year. Smoking tobacco delivers nicotine to the neuroreceptors responsible for addiction, affecting the nervous system and causing addiction. A new study, led by scientists from the University of Bristol, into the molecular interactions involved has revealed how these neuroreceptors respond to nicotine.

Unused stockpiles of nuclear waste could be more useful than we might think, according to new study
Chemists have found a new use for the waste product of nuclear power - transforming an unused stockpile into a versatile compound which could be used to create valuable commodity chemicals as well as new energy sources. Depleted uranium (DU) is a radioactive by-product from the process used to create nuclear energy.

Catalytic protocells get zingy
From the synthesis of drugs to the generation of plastics, catalysts - substances that speed up chemical reactions without being consumed - are the backbone of many industrial processes. Catalysts come in many forms such as inorganic nanoparticles, organic liquids and aqueous enzymes, and can be linked to solid surfaces to increase their performance.

New way to sustainably make chemicals by copying nature’s tricks
Researchers have copied the way organisms produce toxic chemicals without harming themselves, paving the way for greener chemical and fuel production. The new technique, pioneered by Imperial College London scientists, could reduce the need to use fossil fuels to create chemicals, plastics, fibres and fuels.
