Polymer tied in celtic knots | Chemistry World

Polymer tied in celtic knots | Chemistry World – Celtic knots and ancient art have inspired a new way of synthesising polymers. The slow-motion method of controlling polymer growth produces a single chain that when linked repeatedly, intricately wraps around itself to form a dense structure. Scientists at the University of Ireland, Galway, say their […]

Solving the mystery of how cigarette smoking weakens bones

Solving the mystery of how cigarette smoking weakens bones – Almost 20 years after scientists first identified cigarette smoking as a risk factor for osteoporosis and bone fractures, a new study is shedding light on exactly how cigarette smoke weakens bones. The report concludes that cigarette smoke makes people produce excessive amounts of two proteins that trigger a natural body process that breaks down bone.
