Shoppers in Sierra Leone rushed to stock up on food Thursday ahead of a three-day nationwide shutdown, during which the country's 6 million people will be confined to their homes while volunteers search house-to-house for Ebola victims in hiding and hand out soap in a desperate bid to slow the accelerating outbreak.
Ensuring that corn absorbs the right balance of nitrogen, phosphorus and potassium is crucial to increasing global yields. A review of data from more than 150 studies from the U.S. and other regions showed that high yields were linked to production systems in which corn plants took up key nutrients at specific ratios— nitrogen and phosphorus at a ratio of five-to-one and nitrogen and potassium at a ratio of one-to-one.
headache for public health officials. To help address the challenge, a three-continent research consortium is evaluating a novel environmental crowdsourcing technique that relies on 53-cent test kits and the nation’s ubiquitous mobile phone service.
The price of solar energy in the U.S. continues to fall substantially, according to the latest editions of two annual reports. A third report shows that local permitting and other regulatory procedures can significantly impact residential photovoltaic prices.
Think the flu's only a big threat to kids and seniors? Influenza hospitalized a surprisingly high number of young and middle-aged adults last winter— and this time around, the government wants more of them vaccinated.
For future astronauts, the process of suiting up may go something like this: instead of climbing into a conventional, bulky, gas-pressurized suit, one may don a lightweight, stretchy garment, lined with tiny, muscle-like coils. The suit would then be plugged in to a spacecraft’s power supply, triggering the coils to contract and essentially shrink-wrap the garment around the body.
A wild berry native to North America may strengthen the effectiveness of a chemotherapy drug commonly used to treat pancreatic cancer. A new study suggests that adding nutraceuticals to chemotherapy cycles may improve the effectiveness of conventional drugs, particularly in hard to treat cancers.
Chevron has become the first energy company to meet a new set of voluntary shale gas drilling standards that aim to go beyond existing state laws in Pennsylvania, Ohio and West Virginia, the Pittsburgh-based Center for Sustainable Shale announced today.
The mystery of what kick-started the motion of our earth's massive tectonic plates across its surface has been explained by researchers. Their new model also makes a number of predictions explaining features that have long puzzled the geoscience community.
Have you ever have the burger vs. salad debate at your favorite fast food joint? When it comes to your health, this seems like a simple decision, but a deeper look at the Nutrition Facts from each restaurant could change your mind.
Using artificial sweeteners may set the stage for diabetes in some people by hampering the way their bodies handle sugar, suggests a preliminary study done mostly in mice. The researchers and outside experts said more study is needed, while industry groups called the research limited and said other evidence shows sweeteners are safe and useful for weight control.
Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity.
The idea of the Ebola virus becoming airborne is not far-fetched as its ability to enter cells that line the trachea and lungs has been shown under controlled laboratory conditions, a virus expert says.
A fevered search for the next great high-energy, rechargeable battery technology is on. Scientists are reporting they have overcome key obstacles toward making lithium-sulfur batteries, which have the potential to leave today’s lithium-ion technology in the dust.
From the most parched areas of Saudi Arabia to water-scarce areas of the western U.S., the idea of harvesting fog for water is catching on. Now, a novel approach to this process could help meet affected communities’ needs for the life-essential resource.
