When cancer is confined to one spot in the body, doctors can often treat it with surgery or other therapies. Much of the mortality associated with cancer, however, is due to its tendency to metastasize, sending out seeds of itself that may take root throughout the body. The exact moment […]

If you’ve ever had a bad case of jet lag, you know how a disruption to your body’s circadian rhythm makes it difficult to function. Molecular circadian “clocks” exist in cells throughout the body, governing more than just sleep and wake cycles — they are crucial to many aspects of […]

Exposure to mutagens, or mutation-causing agents, can not only bring about changes in DNA but also appear to induce errors when genes are transcribed to make proteins, which may be an important factor in age-related diseases. USC Leonard Davis School of Gerontology Assistant Professor Marc Vermulst and colleagues made the discovery by […]

Using stem cells to regenerate parts of the skull, USC scientists partially corrected a skull deformity and reversed learning and memory deficits in young mice with craniosynostosis, a condition estimated to affect 1 in every 2,500 infants born in the United States. The only current therapy is complex surgery within […]

The study, published in Science Immunology, analysed antibody and T cell responses in 136 London healthcare workers who had mild or asymptomatic Covid-19 infection dating back to March 2020. The team, including researchers from Queen Mary, Imperial College London and University College London, found that 89 per cent of healthcare workers […]

Researchers have discovered and identified sub-types of ovarian cancer cells, which can then be used to accurately identify which ovarian cancer subtypes are likely to lead to more severe cancer outcomes – an approach which has been dubbed the ‘Oxford Classification of Carcinoma of the Ovary’ or ‘Oxford Classic’ for […]

New study shows targeting arterial stiffening earlier in a person’s lifespan could provide cognitive benefits in older age and may help to delay the onset of dementia. Researchers at the University of Oxford and University College London investigated 542 older adults who received two measurements of aortic stiffness, at 64 […]

Research into motion sensitivity could lead to improved rehabilitation programmes and an improvement in building designs for people with a rare inner ear condition that affects their balance. Dr Jessica Tyrrell at the University of Exeter’s Medical School will use the VSimulators research facility at Exeter Science Park to explore the response […]

Dietary fiber found in grains is a large component of many diets, but little is understood about how we digest the fiber, as humans lack enzymes to break down the complex molecules. Some species of gut bacteria break down the fiber in such a way that it not only becomes […]

A new University of Saskatchewan (USask) study has found that stretching is superior to brisk walking for reducing blood pressure in people with high blood pressure or who are at risk of developing elevated levels. Walking has long been the prescription of choice for physicians trying to help their patients […]

The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the most abundant type of RNA within cells, when resources are scarce and the bacteria Escherichia coli needs to slow its growth. Researchers used cryo-electron microscopy (cryo-EM) to capture the structures […]

Researchers have shown that the link between physical and mental illness is closer than previously thought. Certain changes in physical health, which are detectable in childhood, are linked with the development of mental illness in adulthood. The researchers, led by the University of Cambridge, used a sample of over 10,000 […]
