  • Natural killer cells remember and effectively target ovarian cancer

    Natural killer cells remember and effectively target ovarian cancer

    Researchers at Karolinska Institutet have uncovered a unique ability of a special subtype of natural killer cells in the immune system, called adaptive NK cells, to remember ovarian tumours and effectively attack them. The discovery, published in Cancer Immunology Research, could pave the way for new, more powerful immunotherapies for difficult-to-treat cancers.

    NK cells, or natural killer cells, are white blood cells that play a central role in the body’s defence against viral infections…

  • Low iron could cause brain fog during menopause transition

    Low iron could cause brain fog during menopause transition

    New research from the University of Oklahoma sheds light on an understudied area of science: iron levels in the blood and their relationship to cognitive performance in women transitioning into menopause. The findings are good news for women experiencing brain fog and other symptoms.

    Published in the journal Nutrients, the study suggests that when women have adequate levels of iron in their blood during the menopausal transition, they perform better on cognitive tasks. Moreover, sufficient…

  • Left or right arm? New research reveals why vaccination site matters for immune response

    Left or right arm? New research reveals why vaccination site matters for immune response

    Sydney scientists have revealed why receiving a booster vaccine in the same arm as your first dose can generate a more effective immune response more quickly. The study, led by the Garvan Institute of Medical Research and the Kirby Institute at UNSW Sydney and published in the journal Cell, offers new insight that could help improve future vaccination strategies.

    The researchers found that when a vaccine is administered, specialised immune cells called macrophages became ‘primed’ inside…

  • United States sees disproportionate increase in body mass index rates of more than 60

    United States sees disproportionate increase in body mass index rates of more than 60

    In the past 20 years, the average rate of obesity among adults in the United States has risen by approximately 30 percent, but the rate of those with the most severe forms of obesity, or those with a body mass index, or BMI, of more than 60 kg/m2, increased by 210 percent. In a recently published research letter in the medical journal The Lancet: Diabetes & Endocrinology, researchers from Pennington Biomedical analyzed national health data from 2001 through 2023, and discovered the alarming…

  • Influenza virus hacks cell’s internal system

    Influenza virus hacks cell’s internal system

    The influenza virus manipulates the body’s gene regulation system to accelerate its own spread, according to researchers at the University of Gothenburg. Their study also shows that an already approved drug could help strengthen immune defenses — though its effect in humans remains to be confirmed.

    The study, published in the journal Nucleic Acids Research, concerns a previously unknown strategy used by the influenza A virus to take over the body’s own systems. The study shows that the…

  • Study using simulations highlights power of pooled data in environmental health research

    Study using simulations highlights power of pooled data in environmental health research

    Conflicting findings in environmental epidemiology have long stalled consensus on the health effects of toxic chemicals. A new study by Columbia University Mailman School of Public Health published in the American Journal of Epidemiology suggests that one major reason for these inconsistencies may be the limited exposure ranges in individual studies — leading to underpowered results and unclear conclusions.

    Researchers used simulated data to examine how well individual and pooled studies…

  • Updated equestrian helmet ratings system adds racing and high-speed events

    Updated equestrian helmet ratings system adds racing and high-speed events

    Falling off a horse at high-speed changes the impact to the rider’s head and the parameters for a quality helmet, according to new research from the Virginia Tech Helmet Lab.

    Published on April 28 in the Annals of Biomedical Engineering, the findings from researchers Steve Rowson and Lauren Duma indicate that head impacts during falls at high speed generate unique head rotation, which in turn, directly affects helmet behavior.

    “Rotational motion of the head is very important,” said Rowson,…

    Data collection changes key to understanding maternal mortality trends in the US, new study shows

    A new study led by researchers at the University of Oxford, published today (28 April) in JAMA Pediatrics, offers fresh insight into trends in maternal mortality in the United States. For the first time, the study disentangles genuine changes in health outcomes from shifts caused by how deaths are recorded. Nevertheless, the study confirms the devastating impact of the COVID-19 pandemic on maternal death rates for women of all racial and ethnic groups.

    The study, based on data from 2000 to…

  • Urine test could reveal early prostate cancer

    Urine test could reveal early prostate cancer

    A newly published study involving researchers from Karolinska Institutet indicates that prostate cancer can be diagnosed at an early stage through a simple urine sample. With the aid of AI and extensive analyses of gene activity in tumours, they have identified new biomarkers of high diagnostic precision.

    Prostate cancer is one of the most common causes of male death globally. One of the main diagnostic hurdles is the lack of exact biomarkers able to identify the presence of an early…

    Largest osteoarthritis genetic study uncovers pathways to new therapies and repurposed drugs

    Researchers have uncovered multiple new genes and genetic pathways that could lead to repurposing hundreds of existing drugs for osteoarthritis, the most common form of arthritis.

    The research, which analyzed data from nearly 2 million people in diverse populations worldwide, was recently published in Nature. It represents an extensive genetic exploration of osteoarthritis, a condition affecting over 600 million people globally.

    Conducted by an international team led by Helmholtz Munich in…
