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
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
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.

Recyclable ’veggie’ battery could power future devices
A new type of 3D-printed battery which uses electrodes made from vegetable starch and carbon nanotubes could provide mobile devices with a more environmentally-friendly, higher-capacity source of power. A team of engineers led from the University of Glasgow have developed the battery in a bid to make more sustainable lithium-ion batteries capable of storing and delivering power more efficiently.

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.

New facility at University of Birmingham accelerates battery recycling research
Researchers working on the Faraday Institution ReLiB (Recycling and Reuse of Li-ion Batteries) project have completed the installation of new battery testing and storage facilities at the University of Birmingham. The new facilities will allow battery scientists and engineers to speed up their research to develop safe, economic and environmentally sound recycling routes that recover large volumes of valuable materials contained in batteries at the end of their first life.

Light-emitting tattoo engineered for the first time
Scientists at UCL and the IIT -Istituto Italiano di Tecnologia (Italian Institute of Technology) have created a temporary tattoo with light-emitting technology used in TV and smartphone screens, paving the way for a new type of "smart tattoo" with a range of potential uses. The technology, which uses organic light-emitting diodes (OLEDs), is applied in the same way as water transfer tattoos.

New method developed for ’up-sizing’ mini organs used in medical research
A team of engineers and scientists has developed a method of 'multiplying' organoids: miniature collections of cells which mimic the behaviour of various organs and are promising tools for the study of human biology and disease. We need to find the right conditions to help the cells in mini-organs self-organise Yan Yan Shery Huang The researchers, from the University of Cambridge, used their method to culture and grow a 'mini-airway', the first time that a tube-shaped organoid has been developed without the need for any external support.

How vitamins, steroids and potential antivirals might affect SARS-CoV-2
Evidence is emerging that vitamin D - and possibly vitamins K and A - might help combat COVID-19. A new study from the University of Bristol published in the journal of the German Chemical Society Angewandte Chemie has shown how they - and other antiviral drugs - might work. The research indicates that these dietary supplements and compounds could bind to the viral spike protein and so might reduce SARS-CoV-2 infectivity.
