Agricultural fires dot Mexico

2013-05-04
(Press-News.org) In Guerrero, Oaxaca, Michoacan, Colima, and Jalisco regions (as well as others in the Yucatan Peninsula) of Mexico hundreds of fires were detected by the MODIS instrument on the Aqua satellite. 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 Mexico, the agricultural burning season usually occurs several months (March through May) before the growing season of June through October.

This natural-color satellite image was collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite on May 02, 2013. Actively burning areas, detected by MODIS's thermal bands, are outlined in red.

Tohoku earthquake and tsunami focus of BSSA special issue

2013-05-04
SAN FRANCISCO, May 3, 2013 – The 2011 Tohoku earthquake is the best recorded and most studied giant earthquake, resulting in a remarkable suite of observations. A special issue of the Bulletin of the Seismological Society of America (BSSA) captures the latest progress in understanding what happened when this massive M >9 earthquake struck offshore of Japan and produced a devastating tsunami that claimed almost 20,000 lives and precipitated the world's second worst nuclear power plant disaster. "While not the final word, this special issue synthesizes the latest understanding ...

Unusual comparison nets new sleep loss marker

2013-05-04
For years, Paul Shaw, PhD, a researcher at Washington University School of Medicine in St. Louis, has used what he learns in fruit flies to look for markers of sleep loss in humans. Shaw reverses the process in a new paper, taking what he finds in humans back to the flies and gaining new insight into humans as a result: identification of a human gene that is more active after sleep deprivation. "I'm calling the approach cross-translational research," says Shaw, associate professor of neurobiology. "Normally we go from model to human, but there's no reason why we can't ...

NASA sees sun emit mid-level flare

2013-05-04
The sun emitted a mid-level solar flare, peaking at 1:32 pm EDT on May 3, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, and the radio blackout for this flare has already subsided. This flare is classified as an M5.7-class flare. M-class flares are the weakest flares ...

Birth of a black hole

2013-05-04
A new kind of cosmic flash may reveal something never seen before: the birth of a black hole. When a massive star exhausts its fuel, it collapses under its own gravity and produces a black hole, an object so dense that not even light can escape its gravitational grip. According to a new analysis by an astrophysicist at the California Institute of Technology (Caltech), just before the black hole forms, the dying star may generate a distinct burst of light that will allow astronomers to witness the birth of a new black hole for the first time. Tony Piro, a postdoctoral ...

Identifying inhibitors of human proteins that promote tumor formation

2013-05-04
New Rochelle, May 2, 2013–Tumor repressor genes, which inhibit tumor formation, can be "turned off" due to undesirable molecular changes affecting the chromosomes on which the genes reside. Understanding and being able to control these alterations could lead to new approaches for activating or inactivating genes linked to cancer. A novel, high-throughput screening method used to identify agents that can block one chemical modifier that plays a key role in some forms of cancer is described in ASSAY and Drug Development Technologies, a peer-reviewed journal published from ...

Predicting the path to death and helping patients cope with end-stage heart failure

2013-05-04
New Rochelle, NY, May 1, 2013—Congestive heart failure affects more than 5.3 million Americans, is increasing in prevalence, and is ultimately fatal, but the duration and quality of life leading up to death can be unpredictable and vary greatly. Patients and caregivers could better plan for this difficult time if they knew what to expect. Five of the most common scenarios for the last 12 months of life in end-stage heart failure are clearly described in the article "Trajectory of Illness for Patients with Congestive Heart Failure," published in Journal of Palliative Medicine, ...

Preordering lunch increases healthy entree selection in elementary schools

2013-05-04
We all know that buying food when we are hungry is a recipe for disaster. When we are hungry, we can be especially sensitive to sights and smells of foods that will satiate, but may lack in nutrient content. What if we could make our meal choices when we are full, and not anticipating the feeling of satiation we all enjoy? Would we make healthier choices? Researchers at the Cornell Center for Behavioral Economics in Child Nutrition Programs (B.E.N. Center) set out to test whether or not preordering lunch would nudge students make healthier entrée choices. Lunch pre-order ...

Experts to focus on the science of gun safety

2013-05-04
WASHINGTON, DC – Pediatric leaders and researchers will tackle the complex and often politically charged subject of gun violence during a special symposium on Saturday, May 4, at the Pediatric Academic Societies (PAS) annual meeting in Washington, DC. The symposium, "Protecting the Health of Our Children Through Scientific Approaches to Gun Safety and Violence Prevention" will focus on guns and youth, violent media, guns and suicide, the pathway to violence, and community efforts to prevent gun violence. Among the speakers is Dimitri A. Christakis, MD, MPH, FAAP, who ...

Poverty threatens health of US children

2013-05-04
WASHINGTON, DC – Pediatricians, economists, social scientists and policy experts will come together on Saturday, May 4, to address one of the greatest threats to child health — poverty. The group will take part in a plenary session titled, "A National Agenda to End Childhood Poverty," at the Pediatric Academic Societies (PAS) annual meeting in Washington, DC. The session will cover a range of issues related to childhood poverty, including its measurement, its impact on child health and potential solutions. Children are the poorest segment of society: 22 percent of ...

Childhood obesity starts at home

2013-05-04
WASHINGTON, DC – As parents, physicians and policymakers look for ways to curb childhood obesity, they may need to look no further than a child's own backyard. A new study to be presented Saturday, May 4, at the Pediatric Academic Societies (PAS) annual meeting shows that preschool children are less likely to be obese if they live in a neighborhood that is safe and within walking distance of parks and retail services. "A child's neighborhood is a potentially modifiable risk factor for obesity that we can target in order to stop the increasing prevalence of obesity ...
