’Better detection’ for Alzheimer’s and cancers
A new chemical discovery will lead to better monitoring and treatment for cancers and degenerative diseases, according to latest research by scientists. In a paper published today in ChemComm an international team of researchers from the Universities of Birmingham, Bath and the East China University of Science and Technology in Shanghai outline a new approach to detecting 'reactive oxygen' using fluorescence.

New blood stem cell could help solve platelet shortage
A new type of bone marrow stem cell in mice that is primed to produce large numbers of vital blood-clotting platelets has been discovered. The breakthrough could lead to the development of new treatments to restore platelets in patients who have undergone chemotherapy or a bone marrow transplant. A team funded by the Medical Research Council (MRC), and led by scientists at Oxford University's MRC Weatherall Institute of Molecular Medicine, has reported the discovery in the journal Nature .

Grapefruit biomolecules may herald new treatment for heart disease
New research published in the 'Biochemical Journal' has identified molecules occurring naturally in fruit that may play an important role in the future treatment of heart disease. Molecules called flavanoids, which are found in citrus fruits - particularly grapefruit - have proven effective at reducing the inflammation which can lead to deadly cardiovascular disease.

Electron ’spin’ key to solar cell breakthrough
We should see new materials and solar cells that make use of this very soon Akshay Rao Organic solar cells, a new class of solar cell that mimics the natural process of plant photosynthesis, could revolutionise renewable energy - but currently lack the efficiency to compete with the more costly commercial silicon cells.

Corkscrew shaped light could improve screens and fibre optics
Corkscrew shaped light could improve screens and fibre optics
Next generation screens could slash energy use in TVs, mobiles and tablet PCs following new research on molecules that emit and detect twisted light. Brightly lit displays are a big drain on the energy supplies of mobile devices. Current technologies, such as backlit LCD screens, produce text and images by streaming white light through a series of polarising and colour filters, a process that typically wastes over 75 per cent of the light.

Wave of blue fluorescence reveals pathway of death in worms
Wave of blue fluorescence reveals pathway of death in worms
The final biological events in the life of a worm have been described by scientists at UCL, revealing how death spreads like a wave from cell to cell until the whole organism is dead. Watch video When individual cells die, it triggers a chemical chain reaction that leads to the breakdown of cell components and a build-up of molecular debris.

Senses of smell and vision interact in the eye, Sussex researchers find
Senses of smell and vision interact in the eye, Sussex researchers find
Senses of smell and vision interact in the eye, Sussex researchers find New research by Sussex neuroscientists suggests that the interaction between smell and sight occurs not just in the brain, but starts in the eye. The study, carried out by Professor Leon Lagnado's research group in the School of Life Sciences and published in the journal Neuron , has furthered our understanding of how the senses interact with one another.

Rate of ageing may be determined in the womb and linked to birthweight, study reveals
Scientists have found that key metabolites in blood - chemical 'fingerprints' left behind as a result of early molecular changes before birth or in infancy - could provide clues to a person's long-term overall health and rate of ageing in later life. Published today in the International Journal of Epidemiology , the study of twins led by King's College London highlights how a technique called metabolomic profiling has revealed a collection of 22 metabolites linked to ageing.

Scientists solve titanic puzzle of popular photocatalyst
Scientists solve titanic puzzle of popular photocatalyst
A breakthrough in our understanding of the properties of titania (titanium dioxide) - the basis of self-cleaning window technology - has been made by scientists at UCL, uncovering a decades old misunderstanding that has clouded our knowledge of how mixed phase titania catalysts operate. By carrying out cutting-edge computational simulations alongside precise experimental measurements of physical samples of the mineral, scientists at UCL found that the widely accepted explanation for how mixed phase titania catalysts operate was misguided.

The quantum secret to alcohol reactions in space
Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space. To explain the impossible, the researchers propose that a quantum mechanical phenomenon, known as ‘quantum tunnelling’, is revving up the chemical reaction.

Targeted drug delivery could be transformed by microbubble technology
Targeted drug delivery could be transformed by microbubble technology
Scientists have found a way to illuminate tiny bubbles which are used to track blood flow with medical imaging. In future such bubbles could also deliver targeted drugs in the body. Until now, researchers have been unable to accurately study the flexibility of microbubble shells, which are injected into the bloodstream as an aid to ultrasound imaging.

Why our prehistoric, parasitic ’jumping’ genes don’t send us into meltdown
A team of researchers, led by academics at The University of Nottingham, has explained why the so-called 'jumping genes' found in most living organisms don't ultimately kill off their hosts, putting an end to a long-standing scientific mystery. The study reveals for the first time how the movement and duplication of segments of DNA known as transposons, is regulated.

Why jumping genes don’t send us into meltdown
Scientists have explained, for the first time, how transposition is regulated in the bodies of humans and other living organisms. This is an ingenious mechanism which prevents transposons from increasing and killing us. The process is very simple, but it explains so much. Karen Lipkow A team of researchers has explained why the so-called "jumping genes" found in most living organisms don't ultimately kill off their hosts, putting an end to a long-standing scientific mystery.

Diving mammals evolved underwater endurance
Scientists at the University of Liverpool have shed new light on how diving mammals, such as the sperm whale, have evolved to survive for long periods underwater without breathing. The team identified a distinctive molecular signature of the oxygen-binding protein myoglobin in the sperm whale and other diving mammals, which allowed them to trace the evolution of the muscle oxygen stores in more than 100 mammalian species, including their fossil ancestors.

X-rays reveal new picture of ’dinobird’ plumage patterns
12 Jun 2013 The first complete chemical analysis of feathers from Archaeopteryx, a famous fossil linking dinosaurs and birds, reveals that the feathers of this early bird were patterned – light in colour, with a dark edge and tip to the feather – rather than all black, as previously thought.

Ancient Egyptians accessorised with meteorites
31 May 2013 Researchers at The Open University (OU) and The University of Manchester have found conclusive proof that Ancient Egyptians used meteorites to make symbolic accessories. The evidence comes from strings of iron beads which were excavated in 1911 at the Gerzeh cemetery, a burial site approximately 70km south of Cairo.

Scientists identify molecular trigger for Alzheimer’s disease
New research establishes nature of malfunction in protein molecules that can lead to onset of dementia. We have to solve what happens at the molecular level before we can progress and have real impact Tuomas Knowles Researchers have pinpointed a catalytic trigger for the onset of Alzheimer's disease - when the fundamental structure of a protein molecule changes to cause a chain reaction that leads to the death of neurons in the brain.
