    Cyberbullying in any form can be traumatizing for kids

    As concern grows over adolescent mental health, a new national study adds to the growing body of research showing that cyberbullying should be considered an adverse childhood experience (ACE) — a category of childhood trauma linked to long-term emotional, psychological and physical harm.

    While many assume that only extreme forms of online harassment — like threats or identity-based attacks — can cause significant harm, the findings suggest a more troubling reality: even less visible or…

  • South African study identifies two new breast cancer genes in black women

    South African study identifies two new breast cancer genes in black women

    Genetic factors contribute to some 30% of breast cancer cases in SA, necessitating investment in genomic research in African contexts.

    A seminal genetic study published in Nature Communication has discovered two genetic variants linked to breast cancer in black South African women, deepening knowledge about the genetic basis for this disease in African populations.

    The genome-wide association study (GWAS) of breast cancer is the first to have been done in African women living on the…

  • Focused ultrasound halts growth of debilitating brain lesions

    Focused ultrasound halts growth of debilitating brain lesions

    A new, incision-free technique developed at UVA Health to treat debilitating brain lesions called cerebral cavernous malformations, or cavernomas, has shown great promise in early testing, halting the growth of the lesions almost entirely.

    The new approach could represent a paradigm shift in how the malformations, commonly called CCMs, are treated, the researchers say. The technique uses tiny, gas-filled “microbubbles” propelled by focused sound waves to open the brain’s protective barrier…

  • Shorter radiation therapy after prostate surgery safe, study finds

    Shorter radiation therapy after prostate surgery safe, study finds

    For men who undergo a radical prostatectomy for the treatment of prostate cancer, post-surgery radiation therapy can play a vital role in reducing the risk of recurrence. Despite its benefits, many patients decline or defer radiation because it requires daily sessions for several weeks.

    Now, a new study published in JAMA Oncology and led by UCLA Health Jonsson Comprehensive Cancer Center investigators suggests there may be a faster option. Researchers found that stereotactic body…

  • New stem cell model sheds light on human amniotic sac development

    New stem cell model sheds light on human amniotic sac development

    Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilisation. This is the first model of amniotic sac development after two weeks.

    As described in research published today in Cell, the new model can be used to study the origin and function of the human amnion and help identify previously unknown ways the amniotic sac might support…

  • Improved model system allows researchers to study embryo development

    Improved model system allows researchers to study embryo development

    Research from Ph.D. candidate Bohan Chen in the lab of Idse Heemskerk of the Department of Cell and Developmental Biology at the University of Michigan Medical School and their colleagues improves upon a popular experimental model and in doing so, reveals more of the inner workings of a critical period during the formation of an embryo.

    Scientists study development in part to understand what can go wrong as the body’s structures are formed.

    The ultimate hope is to be able to prevent birth…

    By Palestine Chronicle Staff  

    Their deaths were confirmed in responses sent by the Israeli military to Palestinian human rights organizations, which provided only the dates of death without further details.

    Three more Palestinian detainees from the Gaza Strip have been announced dead in Israeli detention, raising the death toll to 69 since October 2023, prisoner rights organizations said…

  • Study reveals why women tend to have faster heartbeats, men more irregular rhythms

    Study reveals why women tend to have faster heartbeats, men more irregular rhythms

    For decades, doctors and researchers have puzzled over a basic heart rhythm mystery: Why do women tend to have faster heartbeats while men are more likely to develop irregular rhythms like atrial fibrillation (AFib)? Now a new study from The Ohio State University Wexner Medical Center provides some insight.

    The research shows that the sinoatrial node (SAN) — a small but powerful structure in the human heart that serves as its natural pacemaker and initiates every normal heartbeat — runs on…

  • How rearranged genes drive kidney cancer progression

    How rearranged genes drive kidney cancer progression

    In findings from a study led by investigators at the Johns Hopkins Kimmel Cancer Center and the Johns Hopkins Bloomberg School of Public Health, scientists report that they have learned how certain combinations of rearranged genes can promote the progression of a rare type of kidney cancer. The work was supported by the National Institutes of Health.

    The researchers demonstrated that proteins made from these rearranged, so-called fusion genes form tiny liquid droplets inside the cell, where…

    ‘Rogue’ immune cells explain why a gluten-free diet fails in some Celiac patients

    ‘Rogue’ immune cells explain why a gluten-free diet fails in some coeliac patients Scientists have identified mutated immune cell clones that could point to improved treatment for refractory coeliac disease.

    Researchers at the Garvan Institute of Medical Research and UNSW Sydney have discovered why some people with coeliac disease continue to suffer debilitating symptoms despite strictly avoiding gluten.

    The study, published in Science Translational Medicine, used cutting-edge single-cell…
