Bacteria such as E. coli detected in minutes by new technology
Dr Munehiro Asally, Dr James Stratford and colleagues, showed that bioelectrical signals from bacteria can be used to rapidly determine if they are alive or dead.
The findings offer a new technology which detects live bacteria in minutes instead of waiting for lab-test results which can take days.
When 'zapped' with an electrical field, live bacteria absorb dye molecules, causing the cells to light up and allowing them to be counted easily.
This rapid technique can detect antibiotic-resistant bacteria.
Beer and fodder crop has been deteriorating for 6000 years
The diversity of the crop Sorghum, a cereal used to make alcoholic drinks, has been decreasing over time due to agricultural practice. To maintain the diversity of the crop and keep it growing farmers will need to revise how they manage it. According to Professor Allaby and colleagues, different groups of sorghums have ‘rescued’ each other from damage, giving insight into how such crops could be rescued in the future.
The milkweed bug’s orange wings and DNA: how insects’ diets are revealed by the genome
The evolution of Maize is more complex than thought
New evidence reveals that the evolution of Maize in South America is more complex than initially thought, and there was a further geographical area in which partial domestication occurred in the Southwest Amazon - according to an international collaboration of researchers including the University of Warwick, and published in the journal Science.
Crops can be grown in Arsenic contaminated soil without being poisonous
Researchers in Life Sciences are working on ways to contribute to developing safe crops which can be grown in As contaminated soil but reduce the amount of As going to the edible part.
Who wants to live for ever?
Research into the process of ageing hasn’t quite found the key to immortality, but it is revealing the way our bodies change over time and what factors contribute to longer and healthier lives. Evolutionary biologist Dr Andre Pires da Silva is looking at the genetics of a species of roundworm and the length of their lives, with a view to gaining insight into human aging. He has found some astonishing results.
Over the next 5 years NERC (The Natural Environment Research Council) will invest £100m to support PHD students, including those at the University of Warwick, meaning the next generation of world-class scientists trained and engaged in both industrial and academic environmental solutions will be produced by the University.
Enzyme discovery could help in fight against TB
An enzyme structure discovery made by scientists at the University of Warwick could help to eradicate tuberculosis (TB).
Research by a team led by Dr Elizabeth Fullam, has revealed new findings about an enzyme found in Mycobacterium tuberculosis (Mtb) the bacterium that causes TB. TB causes more deaths than any other infectious disease, including from HIV and malaria.
Two million pounds awarded to fight disease in East Africa
The University of Warwick has been awarded £2 million to tackle the spread of viruses in East Africa.
The award has been made to the NIHR Global Health Research Group on the Application of Genomics and Modelling to the Control of Virus Pathogens (GeMVi) in East Africa at the University of Warwick. GeMVi brings together expertise in pathogen sequencing and predicative modelling. Life Sciences academics Professor James Nokes and Professor Matt Keeling are co-investigators.
Memory processes depend on protein ‘off-switch’ – could lead to new Alzheimer’s treatments
Memory, learning and cognitive flexibility depend on a protein ‘off-switch’ in the brain, according to a breakthrough discovery made by an international research collaboration co-led by Dr Mark Wall at the University of Warwick.
This new knowledge could enable us to better understand and combat neurological diseases which inhibit memory, such as Alzheimer’s.
The School of Life Sciences invites applications for four new academic positions to strengthen key research areas in the School. This is part of our strategic growth on the Gibbet Hill Biology campus, supported by investment in a new Interdisciplinary Biomedical Research Building that will bring together researchers from Life Sciences and Warwick Medical School to understand the origins and mechanistic basis of diseases.
Life Sciences gets share of £2.6 million research funding from Diabetes UK
Diabetes UK has committed to invest £2.6 million in 19 brand new projects which aim to make life-changing improvements in diabetes care, and reduce people’s risk of Type 2 diabetes.
The funding will be given to projects looking into Type 1, Type 2 and gestational diabetes.
In one of these projects, Dr Freya Harrison, from the School of Life Sciences, will be using medieval remedies to find new sources of antibiotics. She has already discovered a combination that can kill antibiotic-resistant bacteria in the lab.
Professor R.John Ellis to be presented with 2019 Centenary Award
Professor R.John Ellis, an Emeritus in the School of Life Sciences, has been honoured in the Biochemical Society's annual Awards. The awards recognise scientists for the excellence of their work and the impact it has had within the bioscience community and wider society.
Professor Ellis will be presented with the 2019 Centenary Award for his pioneering research on molecular chaperones and their role in protein folding.
Odd genetics of a tri-sexual worm
In a recent paper published in Current Biology, Dr Andre Pires da Silva and colleagues describe a species of nematode that has three sexes - male, female and hermaphrodite. Auanema rhodensis, the worm featured in the study, uses an unusual reproductive strategy with only one sex chromosome (X). Hermaphrodites and female worms have two X chromosomes; males have just one X chromosome. Researchers found that some hermaphroditic worms will produce sperm with two X chromosomes and eggs with no chromosomes. When the hermaphroditic worms and male worms mate, only more male worms are produced. One possible explanation is that male worms may be important for the species' genetic diversity, providing A. rhodensis with the ability to adapt to changing conditions more efficiently than other species.

VirionHealth receives up to $4.2M from DARPA
University of Warwick spin-out company, VirionHealth - a new biotechnology company developing novel therapeutics for respiratory viral infections, has announced that it has won non-dilutive funding worth up to $4.2 million from the US Defense Advanced Research Projects Agency (DARPA).
Founded in 2017 on pioneering research of Professors Easton and Dimmock in the School of Life Sciences, VirionHealth is developing a new class of biological antivirals to create improved therapeutics for respiratory viral infections, focusing on prevention and treatment of influenza and respiratory syncytial virus (RSV). The company is a world leader in the development of precisely engineered, non-infectious, defective interfering particles. www.virionhealth.com

Brain cells that control appetite identified for first time
Dieting could be revolutionised, thanks to the ground-breaking discovery of the key brain cells which control our appetite. Professor Nicholas Dale in the School of Life Sciences has identified for the first time that tanycytes – cells found in part of the brain that controls energy levels – detect nutrients in food and tell the brain directly about the food we have eaten.
