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.

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.

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.

Greenhouse gas 'feedback loop' discovered in freshwater lakes
Greenhouse gas ’feedback loop’ discovered in freshwater lakes
Latest research finds plant debris in lake sediment affects methane emissions. The flourishing reed beds created by changing climates could threaten to double the already significant methane production of the world's northern lakes.

The complicated biology of garlic
Researchers today generally agree that eating garlic, used for thousands of years to treat human disease, can reduce the risk of developing certain kinds of cancers, cardiovascular disease, and type 2 diabetes, but exactly how it does this is a still a mystery that needs more research.

Researchers identify "smell" given off by malaria-infected children
Children infected with malaria give off a distinctive smell through their skin which makes them even more attractive to mosquitoes, researchers have found. In a new study published today a team including scientists from Cardiff University have been able to identify this unique chemical fingerprint for the very first time, opening up the possibility of developing a system to lure mosquitoes away from human populations.

Improved method of delivering anti-cancer drugs
A new non-toxic method for delivering anti-cancer drugs to specific parts of the human body could mean the end of the severe and nasty side effects associated with many cancer therapies, according to researchers at Cardiff University's School of Pharmacy and Pharmaceutical Sciences. The method involves the use of a new type of a nanotube - a tiny tube used in many applications, including drug delivery.

New class of drugs could help tackle treatment-resistant cancers
Researchers have discovered a new class of drug that has the potential to help cancer patients who no longer respond to existing therapies. The drug may not become available to patients for a number of years yet, but researchers believe that if clinical trials are successful, it could be used to tackle a variety of treatment-resistant cancers.

Unlocking the secrets of ice
Unlocking the secrets of ice
The complex properties of water and ice are not well understood but a team from UCL and the ISIS Neutron and Muon Source have revealed new information about a phase of ice called 'ice II'. Given that water makes up 60% of our bodies and is one of the most abundant molecules in the universe, it's no wonder that water is known as the "matrix of life".  There are many different forms of ice - all of which vary significantly from the ice you'd find in your freezer.

Reading of biological molecules improved up to 100x by doubling the sensors
A coupled system of two miniature detectors called nanopores improves detection of biological molecules, including DNA and markers of early disease. The ability to control the motion of single biological molecules is key to improving a wide range of biophysical and diagnostic applications, such as DNA sequencing and the detection of rare molecules linked to diagnosis and prognosis of disease.

'Wiggling and jiggling': new study helps explain how organisms can evolve to live at different temperatures
’Wiggling and jiggling’: new study helps explain how organisms can evolve to live at different temperatures
The brilliant physicist Richard Feynman famously said that, in principle, biology can be explained by understanding the wiggling and jiggling of atoms. For the first time, new research from the University of Bristol, UK and the University of Waikoto, New Zealand explains how this 'wiggling and jiggling' of the atoms in enzymes - the proteins that make biological reactions happen - is 'choreographed' to make them work at a particular temperature.

Artificial and biological cells work together as mini chemical factories
Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications. The system, created by a team from Imperial College London, encapsulates biological cells within an artificial cell. Using this, researchers can harness the natural ability of biological cells to process chemicals while protecting them from the environment.
