Breast cancer risk can be lowered by avoiding unnecessary medical imaging

ScienceDaily (June 11, 2012) — A report issued by the Institute of Medicine (IOM) last December reviewed all the available scientific data compiled to date about potential environmental risks of breast cancer — factors such as pesticides, beauty products, household chemicals, and the plastics used to make water bottles. Commissioned by the breast cancer foundation Susan G Continue reading

New type of male contraceptive? Key gene essential for sperm development discovered

New type of male contraceptive? Key gene essential for sperm development discovered

ScienceDaily (May 24, 2012) — A new type of male contraceptive could be created thanks to the discovery of a key gene essential for sperm development. The finding could lead to alternatives to the conventional male contraceptives that rely on disrupting the production of hormones, such as testosterone Continue reading

Device may inject a variety of drugs without using needles

Device may inject a variety of drugs without using needles

ScienceDaily (May 24, 2012) — MIT researchers have engineered a device that delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. The device can be programmed to deliver a range of doses to various depths — an improvement over similar jet-injection systems that are now commercially available. Continue reading
