'Virtual biopsy' uses AI to help doctors assess lung cancer
’Virtual biopsy’ uses AI to help doctors assess lung cancer
Researchers have used artificial intelligence (AI) to extract information about the chemical makeup of lung tumours from medical scans. For the first time, they have demonstrated how combining medical imaging with AI can be used to provide a 'virtual biopsy' for cancer patients. Their non-invasive method can classify the type of lung cancer a patient has - which is crucial in selecting the right treatment - and can predict if the cancer is likely to progress.

'Dynamic duo' defences in bacteria ward off viral threats
’Dynamic duo’ defences in bacteria ward off viral threats
Scientists at the University of Southampton have discovered that bacteria can pair up their defence systems to create a formidable force, greater than the sum of its parts, to fight off attack from phage viruses. Understanding how bacteria react to this type of virus is a big step in combatting antimicrobial resistance.

Red light can reduce blood glucose levels
Shining a specific frequency of red light on a person's back for 15 minutes can reduce blood sugar levels, according to a new study from City, University of London and UCL. The researchers found that 670 nm red light stimulated energy production within mitochondria, the tiny powerhouses within cells, leading to increased consumption of glucose.

New research improves accuracy of molecular quantification in high throughput sequencing
A team at Oxford's Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences (NDORMS) has developed a new approach to significantly improve the accuracy of RNA sequencing. They pinpoint the primary source of inaccurate quantification in both short and long-read RNA sequencing, and have introduced the concept of 'majority vote' error correction leading to a substantial improvement in RNA molecular counting.

New molecular toolkit boosts useful molecule production from yeast communities
New molecular toolkit boosts useful molecule production from yeast communities
Imperial scientists have built a toolkit to boost yeast's ability to produce food, materials, and pharmaceuticals by engineering optimal behaviours. Microbes such as bacteria and yeast are increasingly being used to produce components of medicines, biofuels, and food. Indeed, baker's yeast, also known as brewer's yeast, or Saccharomyces cerevisiae , is responsible for the fermentation process used in making beer or bread but it is also used at scale to produce other molecules of value for industry.

Strongest evidence to date of brain's ability to compensate for age-related cognitive decline
Strongest evidence to date of brain’s ability to compensate for age-related cognitive decline
Scientists have found the strongest evidence yet that our brains can compensate for age-related deterioration by recruiting other areas to help with brain function and maintain cognitive performance. Now that we've seen this compensation happening, we can start to ask questions about why it happens for some older people, but not others - is there something special about these people? Ethan Knights As we age, our brain gradually atrophies, losing nerve cells and connections and this can lead to a decline in brain function.

New biocontainment method for industrial organisms
Researchers in the Manchester Institute of Biotechnology (MIB) at The University of Manchester have developed a new biocontainment method for limiting the escape of genetically engineered organisms used in industrial processes. In a paper published in Nature Communications Dr Stefan Hoffmann, lead author on the paper, and Professor Patrick Cai have found that by adding an estradiol-controlled destabilising domain degron (ERdd) to the genetic makeup of baker's yeast (S accharomyces cerevisiae), they can control survival of the organism.

Flying insects become disorientated and trapped by artificial light
Flying insects become disorientated and trapped by artificial light
Slow-motion videos collected and analysed by Imperial College London researchers give us new insights into why nocturnal insects gather around light. A Bug's Life fans might remember the unfortunate trance-like state of a mosquito, who, despite calls to 'not look into the light' just couldn't help it, because 'it is so beautiful.' In fact, phototaxis - the movement of organisms in response to light - has interested researchers for years, and yet the reasons behind nocturnal insects' transfixion with light is highly debated.

Blood test could reveal cause of brain injury in newborn babies
Blood test could reveal cause of brain injury in newborn babies
Researchers from Imperial College London have shown that a blood test can pinpoint the underlying cause of brain injury in newborns. Their study looked at babies with a type of brain injury caused by hypoxia - a lack of oxygen. It found that patterns of gene expression that are detectable in the blood can point to the cause of the injury and tell doctors if the newborn is likely to respond to cooling treatment, commonly used to treat brain injury in infants.

New research into autoimmune liver condition suggests unique cell movements may be driving disease
A Birmingham study reveals a novel cellular phenomenon could be responsible for the onset of primary biliary cholangitis (PBC). Research suggests that a recent understanding of cell movements may help shed light on the mechanisms driving primary biliary cholangitis (PBC), an autoimmune disease which attacks the bile ducts of the liver.

New heart treatment helps the body grow a replacement valve
Replacement heart valves that grow inside the body are a step closer to reality following studies led by researchers at Imperial. Surgery to replace faulty heart valves has been possible for more than 60 years, but the treatment has medical drawbacks, both with mechanical or biological valves. But what if the body's natural repair mechanisms could be harnessed to build a living heart valve, right where it is needed? Recent studies led by researchers at Harefield Hospital and Imperial's National Heart and Lung Institute suggest that this approach is entirely possible.

Alzheimer's disease acquired from historic medical treatments
Alzheimer’s disease acquired from historic medical treatments
Five cases of Alzheimer's disease are believed to have arisen as a result of medical treatments decades earlier, reports a team of UCL and UCLH researchers. Alzheimer's disease is caused by the amyloid-beta protein, and is usually a sporadic condition of late adult life, or more rarely an inherited condition that occurs due to a faulty gene.
