Fires in West Africa

2013-05-02
(Press-News.org) The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite detected hundreds of fires burning in the Congo, the Democratic Republic of the Congo and Angola on May 01, 2013. The fires are outlined in red. Most of the fires burn in grass or cropland.

The location, widespread nature, and number of fires suggest that these fires were deliberately set to manage land. Farmers often use fire to return nutrients to the soil and to clear the ground of unwanted plants. While fire helps enhance crops and grasses for pasture, the fires also produce smoke that degrades air quality. In West Africa, the agricultural burning season usually runs from mid- to late-January, after the year's primary crops are harvested, through April or May, when the next growing season begins.

Regular, moderate exercise does not worsen pain in people with fibromyalgia

2013-05-02
WINSTON-SALEM, N.C., – May 2, 2013 – For many people who have fibromyalgia, even the thought of exercising is painful. Yet a new study from Wake Forest Baptist Medical Center shows that exercise does not worsen the pain associated with the disorder and may even lessen it over time. The findings are published in the current online issue of the journal Arthritis Care & Research. According to Dennis Ang, M.D., associate professor of internal medicine at Wake Forest Baptist and senior author of the study, doing light to moderate exercise over a prolonged period of time improves ...

Persistent pain after stressful events may have a neurobiological basis

2013-05-02
CHAPEL HILL, N.C. – A new study led by University of North Carolina School of Medicine researchers is the first to identify a genetic risk factor for persistent pain after traumatic events such as motor vehicle collision and sexual assault. In addition, the study contributes further evidence that persistent pain after stressful events, including motor vehicle collisions and sexual assaults, has a specific biological basis. A manuscript of the study was published online ahead of print by the journal Pain on April 29. "Our study findings indicate that mechanisms influencing ...

Turning human stem cells into brain cells sheds light on neural development

2013-05-02
Medical researchers have manipulated human stem cells into producing types of brain cells known to play important roles in neurodevelopmental disorders such as epilepsy, schizophrenia and autism. The new model cell system allows neuroscientists to investigate normal brain development, as well as to identify specific disruptions in biological signals that may contribute to neuropsychiatric diseases. Scientists from The Children's Hospital of Philadelphia and the Sloan-Kettering Institute for Cancer Research led a study team that described their research in the journal ...

Fires in Southern Australia

2013-05-02
Today's image of southern Australia shows a combination of both planned fires and some bushfires. Fires are often deliberately set by fire officials and controlled in order to clean out dry underbrush and accumulations of debris. The fire burns away the detritus which could otherwise be the ignition for a devastating bushfire that may easily get out of control. In this image, most of the fires have been planned and are under control, however, there are some that are bushfires which, although started spontaneously, are currently under control by fire officials. This ...

Understanding student weaknesses

2013-05-02
If you had to explain what causes the change in seasons, could you? Surprisingly, studies have shown that as many as 95 percent of people — including most college graduates — hold the incorrect belief that the seasons are the result of the Earth moving closer to or further from the sun. The real answer, scientists say, is that as Earth's axis is tilted with respect to its orbit, when on its journey it is angled inward, the sun rises higher in the sky, and that results in more direct sunlight, longer days, and warmer temperatures. Distance plays no role; we are actually ...

How to get more followers on Twitter

2013-05-02
What do all Twitter users want? Followers – and lots of them. But unless you're a celebrity, it can be difficult to build your Twitter audience (and even some celebs have trouble). Looking at a half-million tweets over 15 months, a first-of-its-kind study from Georgia Tech has revealed a set of reliable predictors for building a Twitter following. The research was performed by Eric Gilbert, assistant professor in Georgia Tech's School of Interactive Computing. Gilbert found that Twitter users can grow their followers by such tactics as: Don't talk about yourself: Informational ...

Satellite instrument package to assess space weather ready for delivery by CU-Boulder

2013-05-02
A multimillion dollar University of Colorado Boulder instrument package to study space weather has passed its pre-installation testing and is ready to be incorporated onto a National Oceanic and Atmospheric Administration satellite for a 2015 launch. Designed and built by CU's Laboratory for Atmospheric and Space Physics, the instrument suite known as the Extreme Ultraviolet and X-ray Irradiance Sensors, or EXIS, is the first of four identical packages that will fly on four NOAA weather satellites slated for launch beginning in 2015. CU-Boulder's EXIS will measure energy ...

Researchers determine where best to place defibrillators

2013-05-02
TORONTO: Prompt use of an automated external defibrillator, or AED, can greatly increase the survival rates of people who suffer a cardiac arrest. And MIE Professor Tim Chan, working with Dr. Laurie Morrison at St. Michael's Hospital, has developed a formula to determine where best to place these costly but life-saving devices. In a paper published in Circulation, Chan and Morrison note that publicly registered AEDs in Toronto are not in the best locations to help victims of cardiac arrest. In fact, less than one in four of all cardiac arrests had an AED close by (within ...

NIST demonstrates transfer of ultraprecise time signals over a wireless optical channel

2013-05-02
By bouncing eye-safe laser pulses off a mirror on a hillside, researchers at the National Institute of Standards and Technology (NIST) have transferred ultraprecise time signals through open air with unprecedented precision equivalent to the "ticking" of the world's best next-generation atomic clocks. Described in Nature Photonics,* the demonstration shows how next-generation atomic clocks at different locations could be linked wirelessly to improve geodesy (altitude mapping), distribution of time and frequency information, satellite navigation, radar arrays and other ...

Health defects found in fish exposed to Deepwater Horizon oil spill

2013-05-02
Three years after the Deepwater Horizon oil spill in the Gulf of Mexico, crude oil toxicity continues to sicken a sentinel Gulf Coast fish species, according to new findings from a research team that includes a University of California, Davis, scientist. With researchers from Louisiana and South Carolina, the scientists found that Gulf killifish embryos exposed to sediments from oiled locations show developmental abnormalities, including heart defects, delayed hatching and reduced hatching success. The killifish is an environmental indicator species, or a "canary in the ...
