Surprising finding in glioblastomas

Glioblastomas are highly aggressive, usually incurable brain tumors. If all therapeutic options are exhausted, patients have an average life expectancy of less than two years. Now researchers have made a surprising discovery: in the vicinity of glioblastomas, they found islands of highly potent immune cells in the neighboring bone marrow of the skull, which play a central role in defending against cancer. The new data may open up prospects for... Read more ›

Most blood thinner dosing problems happen after initial prescription

More than two-thirds of people taking blood thinners take direct oral anticoagulants, or DOACs, which are under- or over-prescribed in up to one in eight patients. A new study finds that most prescribing issues for DOACs occur after a provider writes the initial prescription. Researchers say the findings highlight why patients on DOACs need to be monitored consistently. Read more ›

Human cells for cardiovascular research

The innermost layer of blood vessels is formed by endothelial cells, which in turn play a role in the development of diseases of the cardiovascular system. Human endothelial cells are therefore required for the 'in vitro' investigation of the causes of these diseases. Researchers have now established a highly efficient, cost-effective and reproducible way to generate functional endothelial cells from human induced pluripotent stem cells (hiPSCs) for tests in cell...

What's the weather like in the deep sea?

A new study has revealed how even the deepest seafloors are affected by the daily back-and-forth of the tides, and the change of the seasons, and that currents at the bottom of the ocean are far more complicated than previously thought. These findings are helping us understand the deep-sea pathways of nutrients that support important deep-sea ecosystems, assess where microplastics and other pollutants accumulate in the ocean, and reconstruct past...
