Fungal test could save people from fatal infection
Mucormycosis, commonly known as black fungus disease, spiked during the second wave of the Covid-19 pandemic.
Now, Professor Chris Thornton, a professor in fungal immunology at the university, has developed a prototype lateral flow test, which could save valuable time in getting patients the treatment they need.
The test has been validated using patient samples could be ready to use in hospitals within three years if it passes regulatory checks, project leaders said.

The fugal spores that cause black fungus disease are ever-present in the environment and harmless for most people. The disease is rare and thought to only affect those with compromised immunity.
However, a combination of Covid infection, poorly-managed diabetes and an over-use of steroids to control lung inflammation from Covid led to a spike in infections.
In 2021, there was an epidemic in India, with 40,000 cases leading to 3,500 deaths. Many of the survivors were left with facial disfigurements.
Although still at prototype stage, a new study published in the Journal of Clinical Microbiology has shown the new test to be swift and accurate in identifying the disease.
Professor Thornton, co-author of the study, said: "Mucormycosis is an horrific disease, which spreads rapidly in the body and can leave people horribly facially disfigured, and is often fatal."
"Early diagnosis is crucial for the best outcome. This study shows that our new test is quick and effective.
"These exciting results are a critical milestone in the development and validation of the test, which we aim to commercialise in the next three years."
The study was conducted in partnership with colleagues at Besançon University hospital in France.
Researchers tested the device in patients with mucormycosis, patients with other fungal infections, and patients without fungal infections.
The test detects mucormycosis in 30 minutes with a high level of specificity and sensitivity.

Scientists launch controversial project to create the world's first artificial human DNA
[Source] Researchers at five British universities have launched the Synthetic Human Genome Project (SynHG) with an initial grant of approximately $12.6 million from Wellcome, the U.K.'s largest biomedical research charity. Unveiled on Thursday, the five-year effort is led by molecular biologist Jason W. Chin at the Medical Research Council Laboratory of Molecular Biology in Cambridge and aims to assemble an entire human chromosome, base by base, inside the lab. Writing a genome Instead of tweaking existing DNA with tools such as CRISPR, SynHG will attempt to 'write' long stretches of code before inserting them into cultured human skin cells to study how chromosome architecture drives health and disease. The project builds on Chin's earlier success constructing a fully synthetic E. coli genome. The laboratory playbook blends generative-AI sequence design with high-throughput robotic assembly, allowing scientists to plan and assemble millions of DNA bases. Patrick Yizhi Cai of the University of Manchester, who oversees these methods, says the approach 'leverag[es] cutting-edge generative AI and advanced robotic assembly technologies to revolutionize synthetic mammalian chromosome engineering.' Trending on NextShark: Why experts are cautious Geneticist Robin Lovell-Badge of London's Francis Crick Institute emphasized the importance of understanding not only the scientific potential but also the societal values and risks involved. He warned that as research progresses, there is the possibility of creating synthetic cells that could, if used in humans, lead to tumors or produce novel infectious particles if not carefully designed. Lovell-Badge recommended that any engineered cells should include safeguards, such as inducible genetic kill switches, to ensure they can be eliminated from the body or targeted by the immune system if needed. Sarah Norcross, director of the Progress Educational Trust, echoed the need for transparency and public engagement, highlighting that synthesizing human genomes is controversial and requires researchers and the public to be in active communication. Norcross welcomed the project's built-in social science program, which surveys communities across Asia-Pacific, Africa, Europe and the Americas as the science unfolds and is led by social scientist Joy Yueyue Zhang, as a way to ensure that public interests and concerns are considered from the outset. Trending on NextShark: Road ahead Over the next five years, the consortium will iterate design–build–test cycles, aiming first for an error-free synthetic chromosome representing roughly 2% of human DNA. Alongside the laboratory milestones, the team plans to release an open-access toolkit covering both the technical and governance lessons learned.

Cockermouth MRT called out to Kirk Fell following report of person dead at summit
COCKERMOUTH Mountain Rescue Team were called to an incident after a group of walkers had found a person lying unresponsive and without a pulse on the summit of Kirk Fell. The incident occurred on Sunday, June 29, and due to the nature of the issue, a full callout was needed. The full Team was called out, making its way down Ennerdale Valley in vehicles before ascending Kirk Fell via Baysoar Slack. On Facebook, Cockermouth MRT said: "On arrival it was clear that the individual was sadly deceased. "First on scene ensured the walkers who had found the casualty were ok. The Team then packaged the casualty on a stretcher and transported them back to the vehicles at Black Sail. "Our thanks go to the walkers who looked after the individual until we arrived, and the Team's thoughts go out to the individual and their family."
