Breath test could diagnose pancreatic cancer at an earlier stage
A breath test can detect pancreatic cancer and could mean the disease can be diagnosed at an earlier stage for the first time, say researchers. The test has produced encouraging results in a clinical study and will now be tested in a larger multicentre trial at Imperial College Healthcare NHS Trust and five other London hospitals from October.

Robot chemist discovers new molecules and reactions
Robot chemist discovers new molecules and reactions
A new type of artificial-intelligence-driven chemistry could revolutionise the way molecules are discovered, scientists claim. In a new paper published today in the journal Nature , chemists from the University of Glasgow discuss how they have trained an artificially-intelligent organic chemical synthesis robot to automatically explore a very large number of chemical reactions.

World-first green energy pilot
World-first green energy pilot
Researchers from Cardiff University are piloting a new system that uses ammonia as an energy storage solution. A 1.5m ‘world-first' proof-of-concept demonstrator has been opened at the Rutherford Appleton Laboratory in Harwell, Oxfordshire to test the next-generation technology. Its aim is to create a brand new sustainable system that can generate and use power when required, whilst efficiently storing energy in the form of ammonia when the demand for, or price, of electricity is low.

Molecular oxygen in comet’s atmosphere not created on its surface
Scientists have found that molecular oxygen around a comet is not produced on its surface, as some suggested, but may be from its body. The European Space Agency's Rosetta spacecraft escorted comet 67P/Churyumov-Gerasimenko on its journey around the sun from August 2014 - September 2016, dropping a probe and eventually crashing onto its surface.

New drug and material discoveries to be untangled in VR
Scientists at the University of Bristol have developed new virtual reality (VR) cloud-based tools to help academics and industry progress new drugs, materials and boost the teaching of chemistry. A joint team of computer science and chemistry researchers, in collaboration with developers at Bristol based start-up Interactive Scientific and Oracle Corporation, have used Oracle's public cloud infrastructure to combine real-time molecular simulations with the latest virtual reality technology.

New enzyme boost could hasten biofuel production
Imperial scientists have enhanced the process of using biology to make products such as fuels, plastics, medicines, and cosmetics. This could lead to cheaper and more environmentally friendly biofuel production and more efficient plastic recycling. Bioprocessing, which uses living cells or their components to make products like biofuels, plastics, medicines, and cosmetics, is time consuming and expensive.

New ID pictures of conducting polymers discover a surprise ABBA fan
First ever detailed pictures of conjugated polymers - which conduct electricity and are highly sought after - captured with a novel visualisation technique developed by University of Warwick New approach realises Richard Feynman's famous remark that it would be very easy to make an analysis of any complicated chemical substance; all one would have to do would be to look at it and see where the atoms are" Polymers need alternating pattern of "A"

New type of photosynthesis discovered
The discovery changes our understanding of the basic mechanism of photosynthesis and should rewrite the textbooks. It will also tailor the way we hunt for alien life and provide insights into how we could engineer more efficient crops that take advantage of longer wavelengths of light. The new form of photosynthesis made us rethink what we thought was possible.

Novel molecular designs unlock therapeutic potential of nicotine receptors
Novel molecular designs unlock therapeutic potential of nicotine receptors
Seven million people die each year from smoking related diseases, according to the World Health Organisation, with the annual death toll expected to rise to eight million by 2030. Despite a WHO target to phase out tobacco usage by 2040, smoking remains one of the biggest global public health problems, with low to middle income countries accounting for around 80 per cent of the world's estimated 1.1 billion smokers.

Self-sustaining loop of chemical reactions could revolutionise drug production
Experts from the University of Nottingham have created a self-sustaining circuit of reactions which is a greener and more efficient method of chemical production. In their paper Self-sustaining closed-loop multienzyme mediated conversion of amines into alcohols in continuous reactions Drs Francesca Paradisi and Martina Contente of the University of Nottingham produce chemicals more efficiently through a looped set of reactions using enzymes in flow.

Globular clusters 4 billion years younger than previously thought
Once thought to be formed soon after the Universe itself, new research finds Globular Clusters may be only around 9 billion years old Globular clusters age revised following research into the age of binary star systems within the clusters, with both thought to have been born at the same time Findings may change understanding of how the Milky Way and similar galaxies formed, with well over 100 Globular Clusters known to exist within the galaxy Ne

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.

Rare plant compounds could hold key to treating resistant hypertension
Researchers have discovered new natural compounds in a fig plant species native to Malaysia that could lead to improved treatment for resistant hypertension. Dr Kuan Hon Lim and his team from the University of Nottingham Malaysia have isolated a new class of natural compounds from a local fig plant species that induce vasodilation in aorta tissue, meaning the compounds have the ability to dilate the aorta blood vessels.

Breath test breakthrough for early diagnosis of oesophageal and gastric cancer
A breath test can successfully detect oesophageal and gastric cancer and could be used as a first-line test for patients, say researchers. In a multi-centre clinical trial of 335 patients, the breath test can identify cancer from benign diseases with 85 per cent accuracy. Unlike other methods, the test is non-invasive.

Mini tractor beams help arrange artificial cells into tissue structures
Researchers have used lasers to connect, arrange and merge artificial cells, paving the way for networks of artificial cells that act like tissues. The team say that by altering artificial cell membranes they can now get the cells to stick together like ‘stickle bricks' - allowing them to be arranged into whole new structures.
