Space collaboration including Sussex scientist makes icy discovery which sheds light on the building blocks of life
In a development believed to shed light on the building blocks of life, an international team of scientists, including Prof Wendy Brown from the University of Sussex, has discovered diverse ices in the darkest, coldest regions of space so-far measured, which are around 500 light years from Earth. The discovery within a molecular cloud was made by scientists from the IceAge project, an international consortium of academics using the James Webb Space Telescope (JWST), to observe the building blocks of life.

Scientists open new window on the physics of glass formation
Research from an international team of scientists has cast new light on the physics of vitrification - the process by which glass forms. Their findings, which centre on analysis of a common feature of glasses called the boson peak, could help pave the way for new developments in materials science. The peak can be observed in glass when special equipment is used to study the vibrations of its constituent atoms, where it spikes in the terahertz range.

Researchers unravel the complex reaction pathways in zero carbon fuel synthesis
Researchers have used isotopes of carbon to trace how carbon dioxide emissions could be converted into low-carbon fuels and chemicals. The result could help the chemical industry, which is the third largest subsector in terms of direct CO2 emissions, recycle its own waste using current manufacturing processes.

Recycled gold from SIM cards could help make drugs more sustainable
Recycled gold from SIM cards could help make drugs more sustainable
Researchers have used gold extracted from electronic waste as catalysts for reactions that could be applied to making medicines. Re-using gold from electronic waste prevents it from being lost to landfill, and using this reclaimed gold for drug manufacture reduces the need to mine new materials. Current catalysts are often made of rare metals, which are extracted using expensive, energy-intensive and damaging mining processes.

Winchcombe meteorite holds information about the origin of Earth’s oceans
The Winchcombe meteorite, a rare carbonaceous meteorite which crashed onto a driveway in Gloucestershire, has been found to contain extra-terrestrial water and organic compounds that reveal insights into the origin of Earth's oceans. A new study led by experts from the Natural History Museum and the University of Glasgow reports the orbital history and first laboratory analyses of the Winchcombe meteorite, which was recovered only hours after its spectacular fireball lit up the skies over the UK in February 2021.

Sustainable way to make breast cancer drug could boost South African production
Sustainable way to make breast cancer drug could boost South African production
Researchers have devised a cheaper, more efficient, and sustainable way to produce a breast cancer drug in South Africa. The method is designed to facilitate the development of local pharmaceutical manufacturing capabilities in South Africa that could serve the country and its neighbours. We were able to find a more efficient way to manufacture lapatinib..

Watching lithium in real time could improve performance of EV battery materials
Researchers have found that the irregular movement of lithium ions in next-generation battery materials could be reducing their capacity and hindering their performance. The team, led by the University of Cambridge, tracked the movement of lithium ions inside a promising new battery material in real time.

New ageing test could be gold standard for whisky producers
Researchers at a Scottish university have found a way to use tiny particles of gold to measure the maturity of whisky, which could help distillers with one of the key challenges in the production process. Chemists and bioscientists from the University of Glasgow developed the test, which harnesses a unique property of cask-aged whisky to measure its maturity.

Why living things use ATP as universal energy currency
Why living things use ATP as universal energy currency
An early step in metabolic evolution enabled the emergence of ATP as the universal energy carrier, setting the stage for the origin of life, finds a new study led by UCL researchers. According to the findings published in PLOS Biology , a simple two-carbon compound may have been a crucial player in the evolution of metabolism before the advent of cells.

They can pull water molecules apart using graphene electrodes
Researchers from University of Manchester used graphene as an electrode to measure both the electrical force applied on water molecules and the rate at which these break in response to such force. The researchers found that water breaks exponentially faster in response to stronger electrical forces.

Molecules could target cardio-metabolic diseases
Research over the past two decades has culminated in a -new and promising- approach to developing drugs to treat cardio-metabolic diseases. Diabetes, high blood pressure, stroke and heart disease are examples of cardio-metabolic diseases, which are on the rise around the world. For more than 20 years, scientists in Leeds and Germany have been trying to understand the role that calcium ions - chemical messengers between cells - could play in triggering ill-health.

How fish survive extreme pressures of ocean life
Scientists have discovered how a chemical in the cells of marine organisms enables them to survive the high pressures found in the deep oceans. The deeper that sea creatures live, the more inhospitable and extreme the environment they must cope with. In one of the deepest points in the Pacific - the Mariana Trench, 11 kilometers below the sea surface - the pressure is 1.1 kbar or eight tons per square inch.
