Real and false-color images of Siberia
2015-05-14
(Press-News.org) The Aqua satellite's MODIS (Moderate Resolution Imaging Spectroradiometer) instrument took this image of the fires in Siberia. The top image shows the full sized false color image of the area highlighting the burn scars from previous fires.
The sliding "before and after" image shows the real and false color images side-by-side for comparison. The left side shows current fires burning denoted by the red spots. These spots show areas 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. Most probably these fires have been set by farmers to clear fields for agricultural use. In April of this year, farmers were setting fires to clear their fields and the fires grew out of control. There was loss of life and quite a bit of devastation from these fires. The false-color (short-wave infrared, near infrared, and green) of the same image on the right shows the burn scars. Most likely some of these scars are from the fires that burned out of control in April.
NASA's Aqua satellite collected this natural-color image with the MODIS instrument on May 13, 2015. Actively burning areas, detected by MODIS's thermal bands, are outlined in red. NASA image courtesy Jeff Schmaltz LANCE/EOSDIS MODIS Rapid Response Team, GSFC. Caption by Lynn Jenner

Soft matter encompasses a broad swath of materials, including liquids, polymers, gels, foam and - most importantly - biomolecules. At the heart of soft materials, governing their overall properties and capabilities, are the interactions of nano-sized components. Observing the dynamics behind these interactions is critical to understanding key biological processes, such as protein crystallization and metabolism, and could help accelerate the development of important new technologies, such as artificial photosynthesis or high-efficiency photovoltaic cells. Observing these ...

DNA damage caused by smoking can be detected in cheek swabs, finds research published today in JAMA Oncology. The study provides evidence that smoking induces a general cancer program that is also present in cancers which aren't usually associated with it - including breast and gynaecological cancers.
The research team, led by Professor Martin Widschwendter, Head of the Department of Women's Cancer at the UCL Institute for Women's Health and Dr Andrew Teschendorff (UCL Cancer Institute) looked at epigenetic alterations - changes to the DNA that switch genes on and off. ...

May 14, 2015 - For medical practices, having more unique doctors on staff and having doctors see more patients doesn't necessarily lead to improved patient outcomes--and in fact, may have the opposite effect, according to a brief report in the June issue of Medical Care. The journal is published by Wolters Kluwer.
The study shows that high blood pressure (BP) is less likely to normalize during times when the number of unique doctors on staff is higher and more patients are seen, suggesting that "[W]hen practices are busier, BP care may suffer," writes Nancy R. Kressin, ...

Automated analysis of the vital signs commonly monitored in patients being transported to trauma centers could significantly improve the ability to diagnose those with life-threatening bleeding before they arrive at the hospital, potentially saving their lives. In the May issue of the journal Shock, a research team from Massachusetts General Hospital (MGH), the U.S. Army, air ambulance service Boston MedFlight, and two other Boston trauma centers report successful field testing of a system that simultaneously analyzed blood pressure, heart rate, and breathing patterns during ...

Scientists have made an important step towards understanding how volcanic eruptions happen, after identifying a previously unrecognised potential trigger.
An international team of researchers from the University of Liverpool, Monash University and the University of Newcastle (Australia) think their findings could lead to new ways of interpreting signs of volcanic unrest measured by satellites and surface observations.
Dr Janine Kavanagh, from the University of Liverpool's School of Environmental Sciences and lead author of the research paper, said: "Understanding the ...

Led by Georgia State University, researchers have developed the first robust and noninvasive detection of early stage liver cancer and liver metastases, in addition to other liver diseases, such as cirrhosis and liver fibrosis.
Their findings were published Wednesday (May 13) in Proceedings of the National Academy of Sciences.
More than 700,000 people are diagnosed with liver cancer each year. It is the leading cause of cancer deaths worldwide, accounting for more than 600,000 deaths annually, according to the American Cancer Society. The rate of liver cancer in the ...

The combination of a cholesterol-lowering drug, Bezafibrate, and a contraceptive steroid, Medroxyprogesterone Acetate, could be an effective, non-toxic treatment for a range of cancers, researchers at the University of Birmingham have found.
The findings published in the journal Cancer Research show that the drugs kill cancer cells in a completely new way.
Early stage clinical trials of the drugs in elderly patients with acute myeloid leukaemia (AML) have shown promising results, with survival three months longer on average than standard palliative care. The combination, ...

Alexandria, VA - The evolutionary age of grass has been hotly contested. Scientists have previously dated the earliest grasses to 55 million years ago; after the dinosaurs went extinct. Now, a new 100-million-year-old specimen of amber from Myanmar potentially pushes back grass evolution to the Late Cretaceous.
Scientists from the Oregon State University who studied the amber believe they identified "spikelet" - grass in its flowering state - and a cluster of fossilized ergot, a major ingredient in LSD. While their conclusions are intriguing, and have implications for ...

The knock-on effects of the economic downturn have been explored in economy and psychology. Now researchers are examining the effects of unemployment on an even darker subject - cancer mortality.
One would think that dealing with unemployment was challenge enough. But according to the latest research published in ecancermedicalscience, rises in unemployment are associated with significant increases in prostate cancer mortality.
This is the first study that has systematically explored the consequences that changes in unemployment - in particular the Great Recession ...

ALEXANDRIA, Va. - The American Society of Clinical Oncology (ASCO) today announced results from four major studies to be presented at ASCO's 51st Annual Meeting, May 29-June 2, in Chicago. Findings showed that use of a widely available vitamin pill reduces the risk of non-melanoma skin cancers; that early chemotherapy extends the lives of men with advanced prostate cancers; and that new therapies can improve outcomes for children with a rare form of kidney cancer and adults with relapsed multiple myeloma.
The studies are among the around 5,000 abstracts publicly released ...
