Between walking at a leisurely pace and running for your life, human gaits can cover a wide range of speeds. Typically, we choose the gait that allows us to consume the least amount of energy at a given speed. For example, at low speeds, the metabolic rate of walking is lower than that of running … Read more
Consuming flavonoid-rich items such as apples and tea protects against cancer and heart disease, particularly for smokers and heavy drinkers, according to new research from Edith Cowan University (ECU). Researchers from ECU’s School of Medical and Health Sciences analysed data from the Danish Diet, Cancer and Health cohort that assessed the diets of 53,048 Danes … Read more
Physical manifestations of negative memories in the hippocampus could underlie cognitive symptoms of depression, according to research in mice published in JNeurosci. Inhibiting these manifestations could be a future treatment route. Groups of neurons that are activated after an experience are thought to be the physical representation of memory. These so-called engrams in the hippocampus could … Read more
People generally think of stress and anxiety as negative concepts, but while both stress and anxiety can reach unhealthy levels, psychologists have long known that both are unavoidable — and that they often play a helpful, not harmful, role in our daily lives, according to a presentation at the annual convention of the American Psychological … Read more
Stem cells hold the key to wound healing, as they develop into specialised cell types throughout the body – including in teeth. Now an international team of researchers has found a mechanism that could offer a potential novel solution to tooth repair. Published today (Friday 9 August) in Nature Communications, the study showed that a gene … Read more
Lack of sleep can be dangerous; it is thought to play a role in up to 30% of all motor vehicle crashes and even implicated in catastrophic events, such as the Chernobyl nuclear disaster (1, 2). As sleepy individuals are often unaware of their performance impairments, there is a critical need for objective measures of … Read more
As this year’s Lassa fever outbreak in Nigeria is finally ebbing, the total tally came to more than 600 infected people, one-quarter of them dead. Thousands more die each year, uncounted in rural villages throughout West Africa. With an annual wave of infections and new viral strains emerging, it has never been more important to … Read more
Scientists working on a new tuberculosis (TB) vaccine have achieved a major step forward by showing that a promising TB antigen and a novel vaccine adjuvant can be protected from heat damage with a technique developed at the University of Bath. Their method prevents these crucial vaccine components from spoiling outside of a fridge – … Read more
An analysis of published studies found that Nordic walking – a low impact aerobic activity consisting in walking with poles–can benefit patients with breast cancer by having a positive impact on swelling, physical fitness, disability, and quality of life. The European Journal of Cancer Care analysis, which included nine relevant studies, revealed no adverse effects associated with … Read more
Researchers at the University of Pittsburgh School of Medicine are the first to grow genetically modified miniature human livers in the laboratory, to emulate human liver disease progression and test therapeutics. In a proof-of-concept paper published today in Cell Metabolism, Pitt researchers chronicle how they transformed genetically engineered human cells into functional, 3D liver tissue … Read more
