As ice sheet melts, Greenland's fjords become less salty

As ice sheet melts, Greenland's fjords become less salty

Science
Oct. 13 (UPI) -- New data suggests the water around Greenland is becoming less salty as the island's ice sheet melts.Researchers with Denmark's Aarhus University detailed the impact of melting ice on Greenland's coastal waters in a new paper published this week in the journal Scientific Reports.The loss of ice in Greenland is relatively well documented. Over the last two decades, the island's ice has roughly doubled its melt rate. But few studies have looked at how the influx of freshwater is impacting coastal waters.Since 2003, Aarhus scientists have been analyzing water samples collected from Young Sound and from the sea joust outside the sound. Young Sound is located in northeast Greenland. Between 2003 and 2015, researchers recorded a four-fold increase in the amount of fresh water acc...

Small-business employees less likely to get cancer screenings

SATURDAY, Oct. 14, 2017 -- Waiters, contractors and other employees of America's small businesses are more likely to miss out on cancer screening, mostly because of a lack of insurance, new research shows. "Workers employed at smaller organizations had substantially lower breast, cervical and colorectal cancer screening rates" compared to people working at larger corporations or organizations, American Cancer Society (ACS) researchers reported.And poorer insurance coverage accounted for much of these differences, said the team led by ACS researcher Stacey Fedewa.One breast cancer specialist who reviewed the findings said the issue is an important one, because mammograms, colonoscopies and other screens can save lives -- not to mention health care dollars.So it's crucial to "find ways t...

When North Korea decided to go nuclear, it committed to a huge investment in a program that would bring severe sanctions and eat up precious resources that could have been spent boosting the nation's quality of life.Money well spent?Leader Kim Jong Un seems to think so.North Korea's nuclear and missile development programs have without doubt come at a high cost, but the North has managed to march ever closer to having an arsenal capable of attacking targets in the region and — as demonstrated by its July 4 test launch of an intercontinental ballistic missile — the United States' mainland.Good, solid figures for just about anything in North Korea are hard to find. So what follows should be taken as ballpark guesses, at best.But here's a look at how much that arsenal might cost Pyongyang, an

The number of children doing an hour of exercise a day falls by nearly 40% between the ages of five and 12.Figures suggest that by the final year of primary school, just 17% of pupils are doing the recommended 60 minutes of physical activity every day.A spokesman for Public Health England described the drop in activity levels as "concerning".More than a third of children in England are overweight by the time they leave primary school.A new survey from Public Health England and Disney looked at the effects of physical activity on children's emotional wellbeingMore than 1,000 children aged five to 11 were questioned, with their parents acknowledging that being active made their children feel happier (79%), more confident (72%), and more sociable (74%).But the survey also found that children'...

Listen up, foodies – the spike in food costs over the past few months has added £21.31 to the average family shopping bill. Nutrient-rich staples such as meat and dairy are the most vulnerable products in line for the hike as farmers struggle to afford feed for their livestock. But there’s no need to let a little thing like the credit crunch get in the way of your healthy habits. We spoke to some leading nutritionists to find out how you can continue to serve up a brilliant menu on the cheap.Write a listSupermarkets are deliberately laid out to encourage you to buy more (you think it’s a coincidence the chocolate bars are by the checkout?), so shopping without a list is dangerous. ‘Plan what you need for the week, make a list and stick to it,’ says Dr Elisabeth Weichselbaum, a nutrition s
