Researchers extract ancient DNA from a 2,900-year-old clay brick, revealing a time capsule of plant life
University of Oxford researchers have contributed to the first successful extraction of ancient DNA from a 2,900 year-old clay brick. The analysis, published today in Nature Scientific Reports , provides a fascinating insight into the diversity of plant species cultivated at that time and place, and could open the way to similar studies on clay material from different sites and time periods.

Almost half of NHS workers surveyed have left their role or are considering it
A significant number of healthcare workers have either left their job or considered changing it because they feel undervalued or have experienced discrimination, according to a new study led by the University of Leicester in collaboration with UCL. The study, published in The Lancet , found that 48% of healthcare workers surveyed had either considered or acted upon changing or leaving their roles.

Ant invasions cause species loss
New research by Cardiff University has measured the impact of ant invasions on native species at a global scale for the first time - finding that the introduction of invasive ants into new environments can reduce species numbers by 53% through competition and predation. Ants play an important role in helping to maintain stable ecosystems, despite this some species of ants have been transported by humans globally and can cause major problems, even contributing to the extinction of some animal species.

Nobel-winning bodily ’pressure sensors’ filmed for first time at Imperial
Researchers have filmed, for the first time, bodily 'pressure sensors' whose discoverers won the 2021 Nobel Prize in Physiology or Medicine. The sensors - ion channels called Piezo1 and Piezo2 - are found throughout the body, from the heart, bladder and kidneys to the immune and nervous systems. I would love to see drugs based on this mechanism developed in the next ten years.

Mississippi mud reveals secrets of Antarctica’s ancient expansion
Study of microscopic fossils taken from Mississippi sediment cores reveals climate feedback that acted as temporary brake on an ancient cooling event Clues about the formation of major ice sheets on Antarctica have been found in mud cores drilled in Mississippi, providing an important lesson about a major climate cooling event, sometimes known as the Grande Coupure or great cut.

Common wasp spreads across UK
The Big Wasp Survey, a citizen science project involving thousands of volunteers throughout the UK, has yielded important genetic insights into the common wasp, reports a study led by UCL researchers. Using data and samples of Vespula vulgaris (a species of yellowjacket wasp known as the Common Wasp) collected by amateur 'citizen scientists', the researchers conducted the first large-scale genetic analysis of the insect across its native range.

Easier diagnosis of childhood fever using a new rapid blood test
Easier diagnosis of childhood fever using a new rapid blood test
A simple blood test which may be able to rapidly diagnose the cause of a child's illness could be 'transformative', say researchers. An international team, led by researchers at Imperial College London, has developed and validated a diagnostic approach capable of simultaneously detecting and distinguishing between 18 infectious or inflammatory diseases - including group B Streptococcus (GBS), respiratory syncytial virus (RSV), and tuberculosis - with the potential to provide a result in a fraction of the time of current diagnostic tests.

Autoimmune diseases and twisting lights: News from the College
Here's a batch of fresh news and announcements from across Imperial. From genes that may increase the risk of autoimmune disease, to new twisting laser lights to visualise molecules, here is some quick-read news from across the College. Neurodegenerative disease dynamics Many neurodegenerative diseases, such as Alzheimer's (AD) and Parkinson's (PD) are associated with the accumulation and aggregation of certain proteins that form deposits in the brain.

International collaboration identifies new breast cancer susceptibility genes
International collaboration identifies new breast cancer susceptibility genes
A large-scale international collaboration has identified new genes associated with breast cancer that could eventually be included in tests to identify women at increased risk of the disease. To our knowledge, this is the largest study of its kind Douglas Easton The study, published today in Nature Genetics , was led by teams at the University of Cambridge and Université Laval, Quebec.

Rapid genome sequencing improves lives and treatment for children with epilepsy
Rapid genome sequencing improves lives and treatment for children with epilepsy
Researchers at UCL and Great Ormond Street Hospital have collaborated with institutes across the world to use rapid genome sequencing to provide a diagnosis for children with unexplained epilepsy and significantly benefit their care. Epilepsy in children ranges in severity and can leave families and carers with many questions about their child's future health.

FGM identified as a leading cause of death in African countries
FGM identified as a leading cause of death in African countries
Female Genital Mutilation is causing thousands of unnecessary deaths every year - researchers are calling for extra effort to stop the practice. Female Genital Mutilation (FGM) is a leading cause of death in the countries where it is practised, with over 44,000 additional women and young girls dying each year, a new study reveals.

Switching 'spin' on and off (and up and down) in quantum materials at room temperature
Switching ’spin’ on and off (and up and down) in quantum materials at room temperature
Researchers have found a way to control the interaction of light and quantum -spin- in organic semiconductors, that works even at room temperature. These new materials hold great promise for completely new applications, since we've been able to remove the need for ultra-cold temperatures Sebastian Gorgon Spin is the term for the intrinsic angular momentum of electrons, which is referred to as up or down.

Reduced grey matter in frontal lobes linked to teenage smoking and nicotine addiction - study
Findings may demonstrate a brain and behavioural basis for how nicotine addiction is initiated and then takes hold in early life, say scientists. Smoking is perhaps the most common addictive behaviour in the world, and a leading cause of adult mortality Trevor Robbins Levels of grey matter in two parts of the brain may be linked to a desire to start smoking during adolescence and the strengthening of nicotine addiction, a new study has shown.

Research helps to identify immunosuppressed people least likely to have COVID-19 antibodies
New research involving the University of Southampton has identified which people with compromised immune systems are less likely to have COVID-19 antibodies - making them more vulnerable to a severe infection. Around one in five people with solid organ transplant, rare autoimmune disease or blood cancer affecting lymphocytes had no COVID-19 antibodies after three or more vaccinations.
