    Digital discovery unlocks durable catalyst for acidic water splitting

    A research team has developed a new method to accelerate the discovery of affordable, stable materials that support clean hydrogen production. Their approach could help make hydrogen — a promising clean energy source — more widely accessible by reducing reliance on costly noble metals.

    Hydrogen can be produced through water splitting, a process that uses electricity to break water molecules into hydrogen and oxygen. This process involves two key reactions: the oxygen evolution reaction…

  • Novel biomarker: Potential to predict and treat skin cancer metastasis

    Novel biomarker: Potential to predict and treat skin cancer metastasis

    Researchers have identified C5aR1 as a novel biomarker for metastasis risk and poor prognosis in patients with cutaneous squamous cell carcinoma (cSCC), the most common type of metastatic skin cancer. The new study’s findings in The American Journal of Pathology, published by Elsevier, found that C5aR1 promotes the invasion of cSCC tumor cells. Its elevated presence suggests that C5aR1 might serve as a useful prognostic marker for metastatic disease and, potentially, a target for future…

  • Findings on the protein that forms loops in the human genome

    Findings on the protein that forms loops in the human genome

    Cohesin is a protein that forms a ring-shaped complex which wraps and alters the DNA molecule shape. It moves through the DNA and creates specific loops in the genetic material which determine the architecture of the genome and gene expression. Some mutations in the genes of the cohesion complex are responsible for rare diseases (cohesinopathies), such as the Cornelia de Lange syndrome (SCdL) or Roberts syndrome, which affect several organs and cause malformations during development.

  • Unlocking precise composition analysis of nanomedicines

    Unlocking precise composition analysis of nanomedicines

    Current regulations for nanomedicines overlook the effects of the different forms of the same element, such as ions, nanoparticles, and aggregates. In a recent study, Japanese researchers developed a new analytical method combining an asymmetric flow field-flow fractionation system and mass spectrometry to separately quantify these forms. This technique allows for better quality control and safety evaluation of metal-based nanomedicines, promoting their development and clinical use, with…

  • How does coffee affect a sleeping brain?

    How does coffee affect a sleeping brain?

    Caffeine is not only found in coffee, but also in tea, chocolate, energy drinks and many soft drinks, making it one of the most widely consumed psychoactive substances in the world.

    In a study published in April in Nature Communications Biology, a team of researchers from Université de Montréal shed new light on how caffeine can modify sleep and influence the brain’s recovery — both physical and cognitive — overnight.

    The research was led by Philipp Thölke, a research trainee at UdeM’s…

  • Researchers find promise in a new peptide drug to combat a deadly brain cancer

    Researchers find promise in a new peptide drug to combat a deadly brain cancer

    A lab-designed molecule developed and extensively studied by scientists with Virginia Tech’s Fralin Biomedical Research Institute at VTC could represent a breakthrough in slowing tumor recurrence in glioblastoma, an aggressive and deadly form of brain cancer.

    In a study published in May in Cell Death and Disease, researchers identified a previously unknown trait of cancer cells that shows promise for therapeutic intervention. The group outlined the mechanism of action and effectiveness of…

  • HIV discovery could open door to long-sought cure

    HIV discovery could open door to long-sought cure

    University of Virginia School of Medicine scientists have uncovered a key reason why HIV remains so difficult to cure: Their research shows that small changes in the virus affect how quickly or slowly it replicates, and how easily or stubbornly it can reawaken from hiding. These insights bring researchers closer to finding ways to flush out the dormant virus and eliminate it for good.

    Thanks to remarkable progress in HIV treatment, the virus can often be suppressed to undetectable levels in…

  • Genetics and therapy type determine second cancer risk after childhood treatment

    Genetics and therapy type determine second cancer risk after childhood treatment

    Physicians caring for survivors of childhood cancer later in life should be aware that survivors’ genetics, in addition to their lifesaving cancer treatment, contribute to the risk for secondary cancers. This finding comes from scientists at St. Jude Children’s Research Hospital who quantified different factors’ contributions to the risk of a second cancer, the primary cause of mortality for long-term survivors. The new research used data from the St. Jude Lifetime Cohort Study (St. Jude…

  • Earlier measles vaccine could help curb global outbreak

    Earlier measles vaccine could help curb global outbreak

    The global measles outbreak must trigger an urgent debate into whether a vaccine should be recommended earlier to better protect against the highly contagious disease during infancy, a new review states.

    The systematic review, led by Murdoch Children’s Research Institute (MCRI), found vaccinating children from as early as four months of age for measles warranted serious discussion given that only 30 per cent of babies in low- and middle-income countries were protected by maternal antibodies…

    Most LGBTQ adults in US don’t feel transgender people are accepted: Poll | LGBTQ News

    By contrast, about six out of 10 LGBTQ adults said gay and lesbian people are generally accepted in the US. 

    A new poll by the Pew Research Centre has found that transgender people experience less social acceptance in the United States than those who are lesbian, gay or bisexual, according to LGBTQ adults.

    About six out of 10 LGBTQ adult participants in the poll said there is “a great deal” or “a fair amount” of social acceptance in the US for gay and lesbian people, according to…
