Evidence lacking about breast implant safety

A review of more than 30 studies seeking answers about silicone gel breast implant safety finds that the studies don’t provide definitive evidence. The new paper may help inspire improved analyses of existing data as well as a new registry to provide better data.

PROVIDENCE, R.I. [Brown University] — Uncertainty about safety has swirled around silicone gel breast implants for years. They were suspended from the market in 1992 and then allowed again in 2006. Throughout, despite many studies, definitive evidence about whether they are linked to health problems ranging from cancer to connective tissue disorders to depression has remained elusive. (more…)

Study Tests Theory that Life Originated at Deep Sea Vents

One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life began. One possibility has grown in popularity in the last two decades – that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world.

Recent research by geochemists Eoghan Reeves, Jeff Seewald, and Jill McDermott at Woods Hole Oceanographic Institution (WHOI) is the first to test a fundamental assumption of this ‘metabolism first’ hypothesis, and finds that it may not have been as easy as previously assumed. Instead, their findings could provide a focus for the search for life on other planets. The work is published in Proceedings of the National Academy of Science. (more…)
