Similarly, the governments of India and Brazil continue to funnel millions of dollars toward plant biotechnology. Most occur without warning. Magnetic resonance imaging and arteriograms can detect conditions that presage stroke but are expensive, time consuming and sometimes painful. Electronics engineers in Kenji Kobayashi's lab at Takushoku University in Hachioji, Japan, developed the thin plastic sensor, which detects the vibrations caused by blood flow. Aneurysms and blockages change the flow and hence the vibrations.
Additional testing is needed before the device is considered reliable enough for clinical use.
The use of chlorine for bleaching and processing wood pulp to make paper is one of industry's dirtiest environmental practices, producing various highly toxic pollutants, including dioxins. While some of these drugs look very much like those currently available, pharmaceutical companies and researchers have a number of tricks up their sleeves. Here's a look at a handful of drugs making their way down the drug-development pipeline. Gilead Sciences is putting its efforts into the development of Tenofovir, its second nucleotide analogue contender. Tenofovir is active against several different viruses, including some that affect monkeys.
