Tuning into cell signals that tell where sensory organs will form inside the ear

Scientists have discovered a cell-to-cell signaling pathway that designates the future location of ear's sensory organs in embryonic mice. By activating this signal, they were able to induce patches of new sensory tissue with hair cells and support cells. This breakthrough suggests a potential avenue for regenerating sensory organs in ...

Body mass index and thrombogenic factors in newly menopausal women

A study published by the American Physiological Society suggests that as body mass index (BMI) increases, so do platelet reactivity and thrombogenic microvesicles, contributing to cardiovascular disease. Higher BMI groups also showed increased traditional cardiovascular risk factors such as blood pressure and triglycerides.

IU chemists develop new 'light switch' chloride binder

Researchers at Indiana University have designed a molecule that binds chloride ions but can be compelled to release them in the presence of ultraviolet light. The 'light switch' properties of this foldamer could be valuable tools for biochemists, allowing them to adjust the availability of chloride in their experiments.
