Greenhouse gas emissions on rice farms underestimated, study finds

Science
Sept. 10 (UPI) -- Climate scientists and policy makers have underestimated the amount of greenhouse gas emitted by rice farms. New research showed rice farms emit significant amounts of nitrous oxide in addition to methane. In recent years, policy makers have worked with rice farmers to reduce methane emissions and conserve water resources by deploying intermittent flooding. As water resources become more scarce, more continually flooded rice farms are likely to adopt intermittent flooding methods. But new research -- published this week in the journal Proceedings. of the National Academy of Sciences -- suggests the reduction in methane emissions achieved by intermittent flooding is undermined by increases in nitrous oxide emissions. "Water management on rice farms needs to be calibrated ...

Many serious surgeries cancelled on the day, study finds

Health
A significant number of patients requiring serious surgery are having operations postponed, a study suggests.Research led by the Royal College of Anaesthetists and University College London looked at more than 26,000 cases in a seven-day period in March last year, across 245 UK hospitals.They found one in seven operations were cancelled on the day of surgery.However, researchers acknowledged it was likely this figure would be lower during quieter periods of the year.Nonetheless, they said the problem needed addressing as it put the health and welfare of patients at risk.The study, published in the British Journal of Anaesthesia, looked at both emergency and planned operations that required a stay in hospital.This would include everything from heart operat...

Egypt finds village that 'predated pharaohs'

Technology
The Egyptian government has found one of the oldest villages ever in the Nile Delta, dating back to before the time of the pharaohs. According to the antiquities ministry, the neolithic site was found in Tell el Samara, a site 140km (87 miles) north of the capital Cairo.Chief archaeologist Frederic Gio said his team discovered silos of animal bones and food which indicated that the area was inhabited by humans as early as 5,000BC.Modern research considers the famous pyramids in Giza to have begun to be built in 2,500BC.According to the ministry, the site contains a number of habitations which date to different periods.

Arsenic, existing drug combo could treat cancer, study finds

Arsenic, existing drug combo could treat cancer, study finds

Health
Aug. 9 (UPI) -- Arsenic in combination with an existing leukemia drug successfully targeted the disease in mice, and offers hope of new treatment for diverse types of cancer, according to a study. Researchers at Beth Israel Deaconess Medical Center's Cancer Center found that arsenic trioxide, or ATO, when used in combination with all-trans retinoic acid was effective against acute promyelocytic leukemia, or APL. The findings were published Wednesday in the journal Nature Communications. "It's gratifying to see this combination of all-trans retinoic acid and arsenic trioxide that my lab discovered to be curative in the treatment of acute promyelocytic leukemia translate into possible approaches for the treatment of other cancers," Dr. Pier Paolo Pandolfi, director of the hospital's Cancder...
Research finds potential treatment for obesity, diabetes

Research finds potential treatment for obesity, diabetes

Health
Aug. 9 (UPI) -- Researchers have identified a potential target to treat obesity and diabetes through regulation of energy in the body, according to a study of mice. In findings released Thursday in JCI Insight, researchers from the Colorado School of Medicine outline the biological function of an epigenetic modifier known as histone deacetylase and its potential as a treatment target. White adipose tissue stores energy and brown adipose tissue produces heat, which in turn expends energy. By increasing energy amounts, the researchers believe a regulatory node could lead to new drugs to treat obesity and diabetes. They learned that deleting HDAC11 in mice stimulates brown adipose tissue formation and the absence of the modifier also triggered beiging of white adipose tissue. "Through our i...
