Farmland fires in Angola

2013-05-30
(Press-News.org) The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite detected hundreds of fires burning in Angola on May 24, 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. This type of field clearing is the easiest and most cost effective for the farmer. While fire helps enhance crops and grasses for pasture, the fires also produce smoke that degrades air quality. Of note: about 80 per cent of farmers throughout the country are smallholders. They cultivate very small plots of land, with very low productivity since the civil war ravaged the nation. This is most likely the reason that this type of field clearing is used so extensively.

Low doses of THC can halt brain damage

2013-05-30
Though marijuana is a well-known recreational drug, extensive scientific research has been conducted on the therapeutic properties of marijuana in the last decade. Medical cannabis is often used by sufferers of chronic ailments, including cancer and post-traumatic stress disorder, to combat pain, insomnia, lack of appetite, and other symptoms. Now Prof. Yosef Sarne of Tel Aviv University's Adelson Center for the Biology of Addictive Diseases at the Sackler Faculty of Medicine says that the drug has neuroprotective qualities as well. He has found that extremely low doses ...

Study: Pedometer program helps motivate participants to sit less, move more

2013-05-30
Indiana University researchers found that a simple program that uses pedometers to monitor how much people move throughout the day was effective at increasing physical activity, decreasing sitting time, a particular problem for office workers, and helping participants drop some pounds. "Even if somebody works out 30 minutes a day, the fact that they're sitting and not moving for long periods of time for the rest of the day is in and of itself detrimental to their health and well-being, physiologically," said Saurabh S. Thosar, an associate instructor at the IU School ...

NASA sees Hurricane Barbara quickly weaken to a depression

2013-05-30
Tropical Storm Barbara strengthened into a hurricane just before it made landfall late on May 29, and after landfall it weakened into a tropical depression. NASA satellite imagery showed that cloud tops warmed and thunderstorms became more fragmented around the storm's center after Barbara made landfall. Barbara is moving across the Isthmus of Tehuantepec today, May 30. Barbara could regenerate over the Bay of Campeche, on the Gulf of Mexico side of Mexico, and satellite imagery is watching Barbara closely. The Bay of Campeche is surrounded on three sides by the Mexican ...

Beaumont study: Nerve stimulation helps with overactive bladder

2013-05-30
Beaumont Health System research finds that symptoms of overactive bladder, or OAB, were reduced in those who received tibial nerve stimulation. The three-year results published in the June issue of The Journal of Urology show participants with urinary frequency, urgency and involuntary loss of urine maintained significant improvement in their symptoms. Tibial nerve stimulation is a painless procedure that takes place in an outpatient setting. A slim needle electrode is inserted in the ankle, near the tibial nerve. It carries electric impulses from a hand-held stimulator ...

Global warming caused by CFCs, not carbon dioxide, study says

2013-05-30
WATERLOO, Ont. (Thursday, May 30, 2013) - Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, according to new research from the University of Waterloo published in the International Journal of Modern Physics B this week. CFCs are already known to deplete ozone, but in-depth statistical analysis now shows that CFCs are also the key driver in global climate change, rather than carbon dioxide (CO2) emissions. "Conventional thinking says that the emission of human-made non-CFC gases such as carbon dioxide has mainly contributed ...

Virginia's 'hybrid' surveillance strategy aided response to contaminated steroid outbreak

2013-05-30
Philadelphia, Pa. (May 30, 2013) – An innovative "hybrid" surveillance strategy—highlighted by close cooperation between public health officials and clinical partners—helped Virginia mount an efficient and effective response to the ongoing outbreak of fungal meningitis and other infections, according to a report in the July/August issue of Journal of Public Health Management and Practice . The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. The Virginia Department of Health (VDH) "worked closely with clinical partners, combining ...

Rheumatoid arthritis patients not taking their medications as prescribed

2013-05-30
A new study conducted in an ethnically diverse and predominantly low income population found that only one-fifth of rheumatoid arthritis (RA) patients had an overall adherence rate to prescribed oral medications at 80% or greater. Findings published today in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), indicate that less than two thirds of medication regimens for non-biologic disease modifying anti-rheumatic drugs (DMARDs) were correctly followed by RA patients. According to ACR estimates, more than one million U.S. adults experience ...

Android antiviral products easily evaded, Northwestern study says

2013-05-30
Think your antivirus product is keeping your Android safe? Think again. Northwestern University researchers, working with partners from North Carolina State University, tested 10 of the most popular antiviral products for Android and found each could be easily circumnavigated by even the most simple obfuscation techniques. "The results are quite surprising," said Yan Chen, associate professor of electrical engineering and computer science at Northwestern's McCormick School of Engineering and Applied Science. "Many of these products are blind to even trivial transformation ...

Water-rock reaction may provide enough hydrogen 'food' to sustain life in ocean's crust or on Mars

2013-05-30
A chemical reaction between iron-containing minerals and water may produce enough hydrogen "food" to sustain microbial communities living in pores and cracks within the enormous volume of rock below the ocean floor and parts of the continents, according to a new study led by the University of Colorado Boulder. The findings, published in the journal Nature Geoscience, also hint at the possibility that hydrogen-dependent life could have existed where iron-rich igneous rocks on Mars were once in contact with water. Scientists have thoroughly investigated how rock-water ...
