  • Nasal spray H5N1 avian influenza vaccine developed

    Nasal spray H5N1 avian influenza vaccine developed

    The State Key Laboratory for Emerging Infectious Diseases at the University of Hong Kong (HKU) and the InnoHK Centre for Virology, Vaccinology and Therapeutics (CVVT) have pioneered an influenza virus vector-based nasal spray vaccine platform and developed a nasal spray H5N1 avian influenza vaccine. During the early COVID-19 pandemic, this platform enabled the rapid development of a nasal spray vaccine in collaboration with mainland China’s Wantai BioPharm. After completing Phase 1-3…

  • Eye health linked to dementia risk

    Eye health linked to dementia risk

    A new University of Otago — Ōtākou Whakaihu Waka study has found a link between our eye health and dementia.

    Dunedin Multidisciplinary Health and Development Study researchers discovered the blood vessels at the back of the eye — called retinal microvasculature — can show early signs someone is at risk of developing dementia.

    Co-lead author Dr Ashleigh Barrett-Young, of the Department of Psychology, says the findings link to previous work by members of the research team, “putting…

  • Genetic predisposition to sedentary behavior increases the risk of cardiovascular diseases

    Genetic predisposition to sedentary behavior increases the risk of cardiovascular diseases

    Although sedentary behaviour may be an evolutionarily selected trait, it is still important to try to be physically active, says a new study conducted at the University of Jyväskylä, Finland. Researchers have shown for the first time that genetic predisposition to sedentary behaviour is associated with a higher risk of developing the most common cardiovascular diseases. A high genetic predisposition to sedentary behaviour can increase the risk of cardiovascular diseases by up to 20%.

  • Students lead breakthrough study on diabetes drugs and dementia risk

    Students lead breakthrough study on diabetes drugs and dementia risk

    Two undergraduate medicine students at University of Galway have led a major study examining how cardioprotective glucose-lowering therapies — medications that lower blood sugar and reduce the risk of heart disease in people with diabetes — affect the risk of developing dementia.

    The research has been published in JAMA Neurology.

    The new study involved a systematic review and meta-analysis of 26 clinical trials involving more than 160,000 participants.

    The researchers found that while most…

  • Handheld device could transform heart disease screening

    Handheld device could transform heart disease screening

    Researchers have developed a handheld device that could potentially replace stethoscopes as a tool for detecting certain types of heart disease.

    The researchers, from the University of Cambridge, developed a device that makes it easy for people with or without medical training to record heart sounds accurately. Unlike a stethoscope, the device works well even if it’s not placed precisely on the chest: its larger, flexible sensing area helps capture clearer heart sounds than traditional…

  • Discovery of mitochondrial protein opens path to therapeutic advances for heart and Alzheimer’s disease

    Discovery of mitochondrial protein opens path to therapeutic advances for heart and Alzheimer’s disease

    Calcium transport into and out of mitochondria — the powerhouses of cells — is central to cellular energy production and cell death. To maintain the balance of calcium within these powerhouses, cells rely on a protein known as the mitochondrial sodium-calcium exchanger, or NCLX. Now, in new research, scientists at the Lewis Katz School of Medicine at Temple University have discovered a novel regulator of NCLX activity, a protein called TMEM65, which helps move calcium out of mitochondria,…

  • Lactic acid bacteria can improve plant-based dairy alternatives

    Lactic acid bacteria can improve plant-based dairy alternatives

    A new study maps how specific lactic acid bacteria can enhance both the flavour and nutritional quality of plant-based dairy alternatives. The findings may have wide-reaching perspectives for the further development of sustainable foods.

    Plant-based dairy alternatives — such as soy, oat, and almond drinks — are produced without animal ingredients for consumers seeking plant-based substitutes for milk and yoghurt. However, many of these products have the similar shortcomings: flavours that…

  • Eating only during the daytime could protect people from heart risks of shift work

    Eating only during the daytime could protect people from heart risks of shift work

    A study led by researchers at Mass General Brigham suggests that, when it comes to cardiovascular health, food timing could be a bigger risk factor than sleep timing

    Numerous studies have shown that working the night shift is associated with serious health risks, including to the heart. However, a new study from Mass General Brigham suggests that eating only during the daytime could help people avoid the health risks associated with shift work. Results are published in Nature Communications….

  • Viral ‘backbone’ underlies variation in rotavirus vaccine effectiveness

    Viral ‘backbone’ underlies variation in rotavirus vaccine effectiveness

    Researchers have shown that differences in the entire rotavirus genome — not just its two surface proteins — affect how well vaccines work, helping to explain why some strains are more likely to infect vaccinated individuals.

    The study, published today as a Reviewed Preprint in eLife, is described by the editors as an important paper. They say the novel approach to estimating rotavirus vaccine effectiveness provides convincing evidence that rotavirus vaccines should be designed based on…

  • Even under stress, male-female pairs had each other’s backs

    Even under stress, male-female pairs had each other’s backs

    When faced with a potential threat, mice often freeze in place. Moreover, when two animals are together, they typically freeze at the same time, matching each other’s periods of immobility.

    In a new study, researchers found that coordination during fear looks different in males and females — and changes when stress is involved.

    Male-female mouse pairs consistently stayed in sync during stressful situations, even when the animals were strangers. Same-sex pairs were more likely to fall out of…
