Smartphone screens effective sensors for soil or water contamination
The touchscreen technology used in billions of smartphones and tablets could also be used as a powerful sensor, without the need for any modifications. Instead of interpreting a signal from your finger, what if we could get a touchscreen to read electrolytes, since these ions also interact with the electric fields? Ronan Daly Researchers from the University of Cambridge have demonstrated how a typical touchscreen could be used to identify common ionic contaminants in soil or drinking water by dropping liquid samples on the screen, the first time this has been achieved.

Lowering the carbon footprint of fabric and plastic manufacturing
Manufacturing of plastics and fabrics could become greener and have a lower carbon footprint, thanks to a new catalyst architecture developed by a team of experts including UCL academics. Propylene, produced from propane, is critical to the manufacture of plastics, fabrics and other chemicals, and is in short supply.

A sharper focus on protein behaviour
A sharper focus on protein behaviour
Scientists have developed a new computational technique that allows them to see in finer detail the way protein molecules behave. Currently, they have relied on laboratory techniques such as X-ray crystallography and cryo-electron microscopy, but those laboratory procedures can disrupt the normal functioning of the molecule.

Robot chemist offers insight into the origins of life
A robotic 'evolution machine' capable of exploring the generational development of chemical mixtures over long periods of time could help cast new light on the origins of life, scientists say. A team of chemists from the University of Glasgow developed the robot, which uses a machine-learning algorithm to make decisions about which chemicals from a selection of 18 to combine in a reactor, and how to set conditions under which the reaction occurs.

'Vegan spider silk' provides sustainable alternative to single-use plastics
’Vegan spider silk’ provides sustainable alternative to single-use plastics
Researchers have created a plant-based, sustainable, scalable material that could replace single-use plastics in many consumer products. It was a surprise to find our research could also address a big problem in sustainability: that of plastic pollution Tuomas Knowles The researchers, from the University of Cambridge, created a polymer film by mimicking the properties of spider silk, one of the strongest materials in nature.

Efficiently ’switching on’ bacteria to produce high-value chemicals
Most high-value chemicals are currently produced using fossil fuels - industrial chemistry's use of petroleum accounts for 14% of all greenhouse gas emissions. An exciting alternative is to engineer bacteria as -cell-factories- with a genetic switch that reroutes their chemistry to produce high-value chemicals, such as biofuels, polymers and pharmaceuticals.

Complex molecules could hold the secret to identifying alien life
A new system capable of identifying complex molecular signatures could aid in the search for alien life in the universe and could even lead to the creation of new forms of life in the laboratory, scientists say. University of Glasgow researchers have developed a new method called Assembly Theory which can be used to quantify how assembled or complex a molecule is in the laboratory using techniques like mass spectrometry.

Discovery of methanol in a 'warm' planet-forming disk
Discovery of methanol in a ’warm’ planet-forming disk
Astronomers have identified the molecule methanol in the 'warm zones' of a protoplanetary disk circling a star about 360 light years from Earth. The finding is significant because although methanol - CH3OH - is one of the simpler complex carbon-based molecules, it is a precursor chemical involved in the creation of more complex substances such as amino acids and proteins, the building blocks of life.

Ancient pottery reveals the first evidence for honey hunting in prehistoric West Africa
Ancient pottery reveals the first evidence for honey hunting in prehistoric West Africa
A team of scientists, led by the University of Bristol, with colleagues from Goethe University, Frankfurt, has found the first evidence for ancient honey hunting, locked inside pottery fragments from prehistoric West Africa, dating back some 3,500 years ago. Honeybees are an iconic species, being the world's most important pollinator of food crops.

Researchers aim to reduce emissions of process which feeds 40% of the world
A new research project is setting out to investigate how to make an industrial process which helps feed nearly half the world's population more sustainable. The Haber-Bosch process, developed in the early 20th Century, was the first economically-viable large-scale ammonia production process. It works by combining nitrogen and hydrogen under high pressures, with the addition of an iron-based catalyst which helps the process work at a moderate temperature.

Traces of Earth's early magma ocean identified in Greenland rocks
Traces of Earth’s early magma ocean identified in Greenland rocks
New research led by the University of Cambridge has found rare evidence - preserved in the chemistry of ancient rocks from Greenland - which tells of a time when Earth was almost entirely molten. It's astonishing that we can even hold these rocks in our hands - let alone get so much detail about the early history of our planet Helen Williams The study, published in the journal Science Advances , yields information on an important period in our planet's formation, when a deep sea of incandescent magma stretched across Earth's surface and extended hundreds of kilometres into its interior.
