Agricultural fires in the Ukraine

Agricultural fires in the Ukraine
2014-09-18
(Press-News.org) Numerous fires (marked with red dots) are burning in Eastern Europe, likely as a result of regional agricultural practices. The body of water at the lower left of this true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image is the Sea of Azov. The Sea is bordered by Ukraine to the northwest, west and southwest and by Russia to the northeast, east, and southeast. To its left is the Black Sea.

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. Each hot spot, which appears as a red mark, is an area where the thermal detectors on the MODIS instrument recognized temperatures higher than background. When accompanied by plumes of smoke, as in this image, such hot spots are diagnostic for fire.

Professional recommendations against routine prostate cancer screening have little effect

Professional recommendations against routine prostate cancer screening have little effect
2014-09-18
DETROIT – The effect of guidelines recommending that elderly men should not be routinely screened for prostate cancer "has been minimal at best," according to a new study led by researchers at Henry Ford Hospital. The study, published as a research letter online in JAMA Internal Medicine, focused on the use of PSA – prostate-specific antigen – to test for prostate cancer. "We found that the effect of the guidelines recommending against the routine screening of elderly men in particular has been minimal at best," says Jesse Sammon, D.O., a researcher at Henry Ford's Vattikuti ...

New insights on an ancient plague could improve treatments for infections

New insights on an ancient plague could improve treatments for infections
2014-09-18
DURHAM, N.C. – Dangerous new pathogens such as the Ebola virus invoke scary scenarios of deadly epidemics, but even ancient scourges such as the bubonic plague are still providing researchers with new insights on how the body responds to infections. In a study published online Sept. 18, 2014, in the journal Immunity, researchers at Duke Medicine and Duke-NUS Graduate Medical School Singapore detail how the Yersinia pestis bacteria that cause bubonic plague hitchhike on immune cells in the lymph nodes and eventually ride into the lungs and the blood stream, where the infection ...

Sensing neuronal activity with light

Sensing neuronal activity with light
2014-09-18
For years, neuroscientists have been trying to develop tools that would allow them to clearly view the brain's circuitry in action—from the first moment a neuron fires to the resulting behavior in a whole organism. To get this complete picture, neuroscientists are working to develop a range of new tools to study the brain. Researchers at Caltech have developed one such tool that provides a new way of mapping neural networks in a living organism. The work—a collaboration between Viviana Gradinaru (BS '05), assistant professor of biology and biological engineering, and ...

No sedative necessary: Scientists discover new 'sleep node' in the brain

No sedative necessary: Scientists discover new sleep node in the brain
2014-09-18
BUFFALO, N.Y. – A sleep-promoting circuit located deep in the primitive brainstem has revealed how we fall into deep sleep. Discovered by researchers at Harvard School of Medicine and the University at Buffalo School of Medicine and Biomedical Sciences, this is only the second "sleep node" identified in the mammalian brain whose activity appears to be both necessary and sufficient to produce deep sleep. Published online in August in Nature Neuroscience, the study demonstrates that fully half of all of the brain's sleep-promoting activity originates from the parafacial ...

Miranda: An icy moon deformed by tidal heating

Miranda: An icy moon deformed by tidal heating
2014-09-18
Boulder, Colo., USA – Miranda, a small, icy moon of Uranus, is one of the most visually striking and enigmatic bodies in the solar system. Despite its relatively small size, Miranda appears to have experienced an episode of intense resurfacing that resulted in the formation of at least three remarkable and unique surface features -- polygonal-shaped regions called coronae. These coronae are visible in Miranda's southern hemisphere, and each one is at least 200 km across. Arden corona, the largest, has ridges and troughs with up to 2 km of relief. Elsinore corona has ...

Research milestone in CCHF virus could help identify new treatments

2014-09-18
SAN ANTONIO, September 18, 2014 – New research into the Crimean-Congo hemorrhagic fever virus (CCHFV), a tick-borne virus which causes a severe hemorrhagic disease in humans similar to that caused by Ebolavirus, has identified new cellular factors essential for CCHFV infection. This discovery has the potential to lead to novel targets for therapeutic interventions against the pathogen. The research, reported in a paper published today in the journal PLoS Pathogens and conducted by scientists at the Texas Biomedical Research Institute and their colleagues, represents ...

A new quality control pathway in the cell

A new quality control pathway in the cell
2014-09-18
Proteins are important building blocks in our cells and each cell contains millions of different protein molecules. They are involved in everything from structural to regulatory aspects in the cell. Proteins are constructed as linear molecules but they only become functional once they are folded into specific three-dimensional structures. Several factors, like mutations, stress and age, can interfere with this folding process and induce protein misfolding. Accumulated misfolded proteins are toxic and to prevent this, cells have developed quality control systems just like ...

Small, fast, and crowded: Mammal traits amplify tick-borne illness

2014-09-18
(Millbrook, N.Y.) In the U.S., some 300,000 people are diagnosed with Lyme disease annually. Thousands also suffer from babesiosis and anaplasmosis, tick-borne ailments that can occur alone or as co-infections with Lyme disease. According to a new paper published in PLOS ONE, when small, fast-living mammals abound, so too does our risk of getting sick. In eastern and central North America, blacklegged ticks are the primary vectors for Lyme disease, babesiosis, and anaplasmosis. The pathogens that cause these illnesses are widespread in nature; ticks acquire them when ...

Curcumin, special peptides boost cancer-blocking PIAS3 to neutralize STAT3 in mesothelioma

2014-09-18
A common Asian spice and cancer-hampering molecules show promise in slowing the progression of mesothelioma, a cancer of the lung's lining often linked to asbestos. Scientists from Case Western Reserve University and the Georg-Speyer-Haus in Frankfurt, Germany, demonstrate that application of curcumin, a derivative of the spice turmeric, and cancer-inhibiting peptides increase levels of a protein inhibitor known to combat the progression of this cancer. Their findings appeared in the Aug. 14 online edition Clinical Cancer Research; the print version of the article will ...
