New insights on how certain blood types may predispose to diseases People with certain blood types are more likely to have blood clots or bleeding conditions, kidney stones, or pregnancy-induced hypertension, suggests a study published today in eLife. The study confirms previously identified connections between certain blood types and the risk of blood clots and bleeding, and makes a new connection between kidney stones and having type B blood as compared to O. The discoveries may lead to new insights on how a person's blood type may predispose them to developing a certain disease. Previous ...

Researchers create a cell library to study how various sugars bind to and interact with receptors Most infectious bacteria and viruses bind to sugars on the surface of our cells. Now researchers from the University of Copenhagen have created a library of tens of thousands of natural cells containing all the sugars found on the surface of our cells. The library may help us understand the role played by sugars and their receptors in the immune system and the brain, the researchers behind the study explain. Sugar is not just something we eat. On the contrary. Sugar is one of the most naturally o...

New microfluidic system effectively isolates cancer spreading cells The survival rate of cancer patients can drop to ten percent or less during metastasis, the spread of cancerous cells to create secondary tumors. Therefore, it is crucial that cancer is detected and treated before metastasis occurs, or at least at its early stages. To spread the cancer, messenger cells known as Circulating Tumor Cells, or CTCs, break off of the original tumor and flow through the bloodstream to create a secondary growth. A team of researchers led by Assistant Professor of Mechanical and Biomedical Engineering...

Altering a mosquito's gut genes shows promise to curb malaria Altering a mosquito's gut genes to make them spread antimalarial genes to the next generation of their species shows promise as an approach to curb malaria, suggests a preliminary study published today in eLife. The study is the latest in a series of steps toward using CRISPR-Cas9 gene-editing technology to make changes in mosquito genes that could reduce their ability to spread malaria. If further studies support this approach, it could provide a new way to reduce illnesses and deaths caused by malaria. Growing mosquito resistanc...

COVID-19 antibodies persist in breast milk for months following mother’s vaccination Nursing mothers who receive a COVID-19 vaccine may pass protective antibodies to their babies through breast milk for at least 80 days following vaccination, suggests new research from Washington University School of Medicine in St. Louis. Our study showed a huge boost in antibodies against the COVID-19 virus in breast milk starting two weeks after the first shot, and this response was sustained for the course of our study, which was almost three months long. The antibodies levels were still high at the end...
