Within them sits some 80,000 years of history, offering researchers tantalizing clues about climate change and the Earth’s past. At least that was the case – until the precious cache of Arctic ice cores was hit by warming temperatures. A freezer malfunction at the University of Alberta in Edmonton has melted part of the world’s largest collection of ice cores from the Canadian Arctic, reducing some of the ancient ice to puddles. The ice cores – long cylinders extracted from glaciers – contain trapped gasses and particles that offer a glimpse into atmospheric history. An ice core from the Penny Ice Cap on Baffin Island lost about a third of its mass, amounting to about 22,000 years of history, while a core from Mount Logan, Canada’s tallest mountain, saw 16,000 years melt away.
Running a Marathon May Cause Kidney Injury
Researchers said the kidney responds to the physical stress of marathon running as if it is injured, in a way similar to what happens in hospitalized patients when the kidney is affected by medical and surgical complications. In the study, 82 percent of the runners had Stage 1 Acute Kidney Injury (AKI) soon after the race. AKI is a condition in which the kidneys fail to filter waste from the blood. The researchers stated that potential causes of the marathon-related kidney damage could be the sustained rise in core body temperature, dehydration, or decreased blood flow to the kidneys that occurs during a marathon, the researchers said in the paper published in the American Journal of Kidney Diseases.
Entertainment TV Exposure Leads to Rise of Populist Politicians
Children addicted to entertainment television are more likely to become socio-politically challenged as adults, leading to voting for populist politicians like Donald Trump, researchers said. The findings showed that children exposed to entertainment television were 13 percent less likely to report an interest in politics and 10 percent less likely to be involved in a voluntary group. Further, they were also more likely to become cognitively disadvantaged. They scored five percent worse than their nonexposed peers in cognitive tests as adults, researchers reported in a working paper from QMUL’s School of Economics and Finance. They compared the voting behaviors of people who lived in regions where Mediaset was broadcast versus those where Berlusconi’s network was unavailable. The results suggested a relationship between exposure to lightfare TV and preferences for populist parties and leaders.
Eating Fresh Fruits Can Cut the Risk of Developing Diabetes
A bowl of fresh fruits a day may lower the risk of developing diabetes by 12 percent, a study has showed. In individuals with diabetes, consuming fresh fruit more than three days a week was associated with a 17 percent lower relative risk of dying. Further, it can lower the risk of developing diabetes-related complications affecting large blood vessels -- ischaemic heart disease and stroke -- and small blood vessels -- kidney diseases, eye diseases, and neuropathy -- by 13-28 percent, the findings revealed. Huaidong Du of the University of Oxford, noted in a paper published in the journal PLOS Medicine, that higher consumption of fresh fruit in people with diabetes, led to a decrease in mortality risk of 1.9 percent at five years, and lower risks of microvascular and macrovascular complications.
Wogging, a Blend of Running and Jogging, is Great for Endurance
Forget the saying ‘slow and steady wins the race’ -- according to a recent study, alternating between walking and running, or wogging, is the best way to conserve energy and reach your destination on time. Ohio State University researchers in the US examined how people budget their time as they travel on foot to reach a destination at a particular appointed time. The study found that when people have neither too much time nor too little time to reach their destination, they naturally switch back and forth between walking and running, which turns out to be the best strategy for saving energy. The study appears in the Journal of the Royal.
