Multiple metals - and possible signs of water - found in unique exoplanet
An international team of researchers have identified 'fingerprints' of multiple metals in one of the least dense exoplanets ever found.  The detection of a trace element such as lithium in a planetary atmosphere is a major breakthrough. Nikku Madhusudhan The team, from the University of Cambridge and the Instituto de Astrofísica de Canarias (IAC) in Spain used the Gran Telescopio Canarias (GTC) to observe WASP-127b, a giant gaseous planet with partly clear skies and strong signatures of metals in its atmosphere.

Scientists use a photonic quantum simulator to make virtual movies of molecules vibrating
Scientists use a photonic quantum simulator to make virtual movies of molecules vibrating
Scientists have shown how an optical chip can simulate the motion of atoms within molecules at the quantum level, which could lead to better ways of creating chemicals for use as pharmaceuticals. An optical chip uses light to process information, instead of electricity, and can operate as a quantum computing circuit when using single particles of light, known as photons.

Improving drug treatments with natural products
Turmeric, shrimp shells, beeswax and cocoa butter are being used to improve the effectiveness of drugs and reduce side effects when treating a range of diseases including cancer and diabetes. Research is being carried out at the University of Nottingham Malaysia to discover how these ‘natural products' can improve the ways drugs are delivered and their efficiency, whilst also minimising any side effects.

Dementia friendly swimming sessions help patients and carers, study finds
Specially organised ‘dementia friendly' swimming sessions can be beneficial to people with dementia and their carers, according to a new study by researchers at the University of Nottingham and the Institute of Mental Health. The team set out to find out what impact swimming sessions have on the lives of people with dementia and how they affect the experience of their carers.

Stars formed only 250 million years after the Big Bang
Stars in a galaxy 13.28 billion light years away formed only 250 million years after the Big Bang, finds a team of international astronomers led by groups at UCL and Osaka Sangyo University in Japan. The discovery shows that stars in the galaxy - called MACS1149-JD1 - formed at an unexpectedly early stage in the age of the Universe and the new observations break the team's own record for detecting the most distant known source of oxygen.

Could a Multiverse be hospitable to life?
Could a Multiverse be hospitable to life?
A Multiverse - where our Universe is only one of many - might not be as inhospitable to life as previously thought, according to new research. Questions about whether other universes might exist as part of a larger Multiverse, and if they could harbour life, are burning issues in modern cosmology. Now new research led by Durham University, UK, and Australia's University of Sydney, Western Sydney University and the University of Western Australia, has shown that life could potentially be common throughout the Multiverse, if it exists.

X-rays from tabletop lasers allows scientists to peer through the ’water window’
Studying the fleeting actions of electrons in organic materials will now be much easier, thanks to a new method for generating fast X-rays. The technique means advanced measurements of fast reactions will now be possible in physics labs around the world, without having to wait to use expensive and scarce equipment.

Gravitational waves help unravel mystery of gamma ray bursts in space
The data collected during historic first detection of a binary neutron star collision is helping astrophysicists further unravel the mystery of gamma-ray bursts in space. Gamma-ray bursts are extremely energetic cosmological events in which massive amounts of gamma-ray light, hundreds of times brighter than a supernova, are released.

Fleet of spacecraft spot long-sought-after process in the Earth’s magnetic field
A NASA mission has discovered an important process explaining the fate of energy contained in the turbulent magnetic fields surrounding the Earth. The phenomenon, discovered by NASA's four-spacecraft Magnetospheric Multiscale (MMS) mission, is small but provides crucial insight into turbulent plasmas.

Nanoscale measurements 100x more precise, thanks to improved two-photon technique
Technique uses photons, fundamental components of light, to measure nanoscopic materials thinner than 100,000th the width of a human hair - with 30,000 fired per second and 500bn throughout Research will mean measurements 100x more precise than existing two-photon techniques - with the potential to aid research into cell membranes and DNA Two-photon technique more stable than existing one-photon technology New technique could also be substantial

Nanoscale measurements 100x more precise thanks to two-photon technique
The precision of measuring nanoscopic structures could be substantially improved, thanks to research involving the University of Warwick and QuantIC researchers at the University of Glasgow and Heriot Watt University into optical sensing. QuantIC is the UK Quantum Technology Hub in Quantum Enhanced Imaging and part of the UK National Quantum Technologies Programme.

The surprising depth of crystal patterns in human bone
Repeating patterns of bone minerals go deeper and smaller than previously thought, Imperial and York researchers have found. Bone is mostly made of the flexible protein collagen, and the hard mineral apatite. The two elements are arranged in nested repeating patterns from the smaller to the larger scale, eventually influencing the overall structure of bone.

Taming the multiverse: Stephen Hawking's final theory about the big bang
Taming the multiverse: Stephen Hawking’s final theory about the big bang
Professor Stephen Hawking's final theory on the origin of the universe, which he worked on in collaboration with Professor Thomas Hertog from KU Leuven, has been published today in the Journal of High Energy Physics .  We are not down to a single, unique universe, but our findings imply a significant reduction of the multiverse, to a much smaller range of possible universes.

Research casts doubt on theories of star formation
The birth of stars from dense clouds of gas and dust may be happening in a completely unexpected way in our own galaxy and elsewhere. This is according to an international team of researchers, including scientists from Cardiff University, who have found that long-held assumptions about the relationship between the mass of star-forming clouds of dust and gas and the eventual mass of the star itself may not be as straightforward as we think.

Weighing single molecules with light
Scientists at Oxford University have developed a light-based measuring technique that could transform our ability to characterise biomolecules. Using a microscope that detects light scattering rather than fluorescence, the researchers have demonstrated that single molecules can be observed, and their mass measured, in solution.

How decisions form in the brain: A physical basis for a cognitive process
In experiments asking fruit flies to distinguish between ever closer concentrations of an odour, the researchers led by Professor Gero Miesenböck had previously identified a tiny minority of about 200 nerve cells in the brain as critical for decision-making. In new work, the team found that these nerve cells collect evidence for the alternative choices as minute voltage changes across their surface.

A dose of empathy may support patients in pain
Research published in the Journal of the Royal Society of Medicine suggests that empathic, positive messages from doctors may be of small benefit to patients suffering from pain, and improve their satisfaction about the care received. The study, which combined data from 28 clinical trials involving over 6,000 patients, adds weight to the argument that patient outcomes can be improved when doctors enhance how they express empathy and create positive expectations of benefit.

Red and yellow paint on Antonine Wall
Dr Louisa Campbell with the Summerston distance stone at The Hunterian Museum University of Glasgow archaeologist using cutting edge technology on remnants of the Antonine Wall has shown parts of it were painted in bright colours. Dr Louisa Campbell's research, which has used x-ray and laser technology to analyse parts of the Roman Empire's most north-western frontier, showed it was painted with vibrant red and yellows.
