Nitrogen and phosphates cause algal overgrowth on corals, which also contributes sugars to the system. It is vital to consider the carbon component as we develop conservation strategie...

Nanotechnology may find disease before it starts

...w study suggests. It would do so by improving the quality of images produced by one of the most common diagnostic tools used in doctors' offices ?the ultrasound machine. In laboratory experiments on mice, scientists found that nano-sized particles injected into the animals improved the resulting images. Th...

World faces challenge as life expectancies lengthen, scientist says

"As the population grows, as incomes grow, and as the baby-boom generation approaches the primary ages of disease-related death, the social value of improvements in health will continue to rise." Many critiques of risi...

Climate change: The rice genome to the rescue

"We also need rice varieties that can take advantage of higher levels of CO2 in the atmosphere, rice that is vigorous enough to recover quickly from extreme weather events and disasters, and very hig...

Low-cost drug gaining favor for use in HIV-infected children in poor countries

...al practice after considering both the content and quality of existing medical trials on a topic. To be included in the Cochrane findings, a study had to be a randomized clinical trial. Grimwade's search turned up only one trial that passed that litmus test: a study of 534 HIV-positive children in Zambia. ...
