New archaeological discoveries reveal birch bark tar was used in medieval England
Scientists from the University of Bristol and the British Museum, in collaboration with Oxford Archaeology East and Canterbury Archaeological Trust, have, for the first time, identified the use of birch bark tar in medieval England - the use of which was previously thought to be limited to prehistory.

Stretchy and squeezy soft sensors one step closer thanks to new bonding method
Imperial College London bioengineers have found a way to create stretchy and squeezy soft sensing devices by bonding rubber to electrical components. Stretchy and squeezy soft sensors that can fit around body parts or squeezed in hands could be used for applications including sports and rehabilitation after injury or stroke.

What protects killer immune cells from harming themselves?
White blood cells, which release a toxic potion of proteins to kill cancerous and virus-infected cells, are protected from any harm by the physical properties of their cell envelopes, find scientists from UCL and the Peter MacCallum Cancer Centre in Melbourne. Until now, it has been a mystery to scientists how these white blood cells - called cytotoxic lymphocytes - avoid being killed by their own actions and the discovery could help explain why some tumours are more resistant than others to recently developed cancer immunotherapies.

UK needs to act to prevent electric vehicle battery waste mountain - new study
Recycling technologies for end-of-life lithium ion batteries (LIBs) are not keeping pace with the rapid rise of electric vehicles, storing up a potentially huge waste management problem for the future, according to a new study. A review of lithium ion battery recycling led by the University of Birmingham suggests that, while electric vehicles (EVs) offer a solution for cutting pollution, governments and industry need to act now to develop a robust recycling infrastructure to meet future recycling need.

Scientists spy unstable semiconductors
Scientists from Cardiff University have, for the first time, spotted previously unseen "instabilities" on the surface of a common compound semiconductor material. The findings could potentially have profound consequences for the development of future materials in the electronic devices that power our daily lives.

Physicists shed new light on how liquids behave with other materials
Using a range of theoretical and simulation approaches, physicists from the University of Bristol have shown that liquids in contact with substrates can exhibit a finite number of classes of behaviour and identify the important new ones. Their findings, published in the Proceedings of the National Academy of Sciences (PNAS) , challenge the accepted wisdom on wetting and drying phase behaviour.

New 3D printing technique for biomaterials
A new way of 3D printing soft materials such as gels and collagens offers a major step forward in the manufacture of artificial medical implants. Developed by researchers at the University of Birmingham, the technique could be used to print soft biomaterials that could be used to repair defects in the body.

New antimicrobial coating could be key in fight against hospital-acquired infections
Scientists at the University of Birmingham have created an antimicrobial coating for steel surfaces which has proven to rapidly kill bacteria that cause some of the most common hospital-acquired infections. Developed by researchers at the University of Birmingham, patented by University of Birmingham Enterprise , and to be commercialised by a new company NitroPep, the coating - also called NitroPep - has been heralded as a new tool in the fight against the spread of infection.

Supercapacitors turbocharged by laxatives
An international team of scientists, including a professor of chemistry from the University of Bristol, has worked out a way to improve energy storage devices called supercapacitors, by designing a new class of detergents chemically related to laxatives. Their paper, published today , explains why these detergents, called ionic liquids, are better electrolytes than current materials and can improve supercapacitors.

Five cool things our surface scientists do
Surface science can make a big difference to our health, well-being and environment. Our surface scientists at Durham have been working on a whole range of applications that have already changed our lives in some way (think mobile phones and puddles) and could make a real difference to people around the world, particularly in developing countries.

New technique could brighten screens and make smartphone batteries last longer
Our future TV and smartphone screens could have double the energy efficiency, thanks to a technique invented by Imperial scientists. The pixels in many modern screens for TVs, smartphones, tablets, and laptops are lit by little devices called OLEDs (organic light emitting diodes). The findings could make screens of all kinds brighter, with better contrast and longer life.

Experts develop nanolasers on silicon
Researchers at Cardiff University have shown tiny light-emitting nanolasers less than a tenth of the size of the width of a human hair can be integrated into silicon chip design. The photonic band-edge lasers can operate at superfast speeds and have the potential to help the global electronics industry deliver a range of new applications - from optical computing to remote sensing and heat seeking, Professor Diana Huffaker is Scientific Director of Cardiff University's Institute for Compound Semiconductors , based at Cardiff University's School of Physics and Astronomy.

Washable, wearable battery-like devices could be woven directly into clothes
Researchers have developed washable, wearable 'batteries' based on cheap, safe and environmentally friendly inks and woven directly into fabrics. The devices could be used for flexible circuits, healthcare monitoring, energy conversion, and other applications. The team, led by Dr Felice Torrisi , who recently joined Imperial from the University of Cambridge, have shown how graphene - an atom-thick sheet of carbon - and other related materials can be directly incorporated into fabrics.

Wonder material: individual 2D phosphorene nanoribbons made for the first time
Tiny, individual, flexible ribbons of crystalline phosphorus have been made and measured an international collaboration, in a world first, and they could revolutionise electronics and fast-charging battery technology. Since the isolation of 2-dimensional phosphorene (the phosphorus equivalent of graphene) in 2014, more than 100 theoretical studies have predicted that new and exciting and properties could emerge by producing narrow 'ribbons' of this material.

Solar-powered supercapacitors could create flexible, wearable electronics
A breakthrough in energy storage technology could bring a new generation of flexible electronic devices to life, including solar-powered prosthetics for amputees. In a new paper published in the journal Advanced Science , a team of engineers from the University of Glasgow discuss how they have used layers of graphene and polyurethane to create a flexible supercapacitor which can generate power from the sun and store excess energy for later use.
