Sushi or Ice Cream, which raises blood sugar more?
November 23, 2015 06:29 AM - , NoCamels
Which is more likely to raise blood sugar levels: Sushi or ice cream? According to a new Israeli study, the answer varies from one person to another. The study, which continuously monitored blood sugar levels in 800 people for a week, revealed that the bodily response to similar foods was highly individual.
The study, called the Personalized Nutrition Project, was led by Prof. Eran Segal and Dr. Eran Elinav of the Weizmann Institute. It was published in the November 19 issue of the scientific journal Cell, and has since stirred up the medical community, which might have to rethink dietary recommendations.
Sea traffic linked to hazardous levels of nanoparticles along coastlines
November 21, 2015 09:20 AM - Staff, ClickGreen
The air along coastlines is being heavily polluted by hazardous levels of nanoparticles from sea traffic, a new study has found.
Almost half of the measured particles stem from sea traffic emissions, while the rest is deemed to be mainly from cars but also biomass combustion, industries and natural particles from the sea.
"This is the first time an attempt has been made to estimate the proportion of nanoparticles stemming from sea traffic. The different types of nanoparticles have previously not been distinguished, but this new method makes it possible", says Adam Kristensson, researcher in Aerosol Technology at the Lund University Faculty of Engineering in Sweden.
US Forest Service proposes coal mining expansion in Colorado
November 20, 2015 10:08 AM - Center for Biological Diversity
National and local conservation groups today condemned a decision by the U.S. Forest Service to continue pressing to open national forest roadless areas in Colorado to coal mining.
In a notice filed today, the Forest Service announced it would move forward by issuing a draft environmental impact statement on the proposal to pave the way for mining. The proposal would reopen a loophole in the “roadless rule” for national forests in Colorado to enable Arch Coal — the nation’s second largest coal company — to scrape roads and well pads on nearly 20,000 acres of otherwise-protected, publicly owned national forest and wildlife habitat in Colorado’s North Fork Valley.
Food industry focuses on sustainable sourcing to mitigate climate change
November 20, 2015 06:59 AM - Sarantis Michalopoulos, EurActiv
Faced with a raw materials scarcity due to climate change, food and drink giants have turned to a sustainable management in order to protect the environment and ensure their future viability. The global population is expected to rise from 7.3 billion today to 9.7 billion in 2050, according to UN projections. As a consequence, according to a survey published in July by FoodDrinkEurope, this will require a 60% increase in food supplies globally, as well as a 30% rise in global demand for water for agriculture.
EVs vs. Gasoline-Powered Cars - Which has the cleaner lifecycle?
November 19, 2015 07:15 AM - Leon Kaye, Triple Pundit
It’s the trick question that has left many of us stumped: from the earliest stages of manufacture to the years driving on the road until they are sent to the junkyard, are conventional automobiles or electric cars cleaner for the environment? While acknowledging that electric vehicles (EVs) emit no emissions when running on our streets and highways, many have assumed that those pesky rare earth metals in their massive batteries and the emissions associated with producing the power canceled out any environmental benefits that their drivers enjoyed. According to the Union of Concerned Scientists (UCS), a two-year study has provided the answer.
New study casts doubt on how much sea levels may rise from the collapse of the Antarctic ice sheet
November 19, 2015 06:54 AM - British Antarctic Survey
A new study by scientists in the UK and France has found that Antarctic ice sheet collapse will have serious consequences for sea level rise over the next two hundred years, though not as much as some have suggested.
This study, published this week in the journal Nature, uses an ice-sheet model to predict the consequences of unstable retreat of the ice, which recent studies suggest has begun in West Antarctica.
An international team of researchers, including a scientist from British Antarctic Survey (BAS), predict that the contribution is most likely to be 10 cm of sea-level rise this century under a mid to high climate scenario, but is extremely unlikely to be higher than 30 cm. When combined with other contributions, that’s a significant challenge for adapting to future sea level rise. But it’s also far lower than some previous estimates, which were as high as one metre from Antarctica alone.
Ice Cap in Iceland gaining mass
November 18, 2015 03:05 PM - NASA Earth Observatory
Winter storms can blanket Iceland almost entirely with snow. The relative warmth of summer and fall, however, exposes a spectacular, varied landscape. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color view of the Nordic island nation on November 9, 2015.
“The visible snow cover is typical for this time of the year, compared to conditions during the past 15-20 years,” said Thorsteinn Thorsteinsson, a glaciologist at the Icelandic Meteorologial Office. He noted, however, that compared to the reference period of 1961-1990, snow cover is “almost certainly” less than average in the highland and mountain regions above 400 meters in elevation.
The melting of seasonal snow cover accentuates the boundaries of Iceland’s permanent ice caps. The ice caps appear smooth and rounded in contrast with the snow-covered interior plateau or the snow-capped ridges along the glacier-carved coastline.
Happiness and frequency of sex linked, to a point
November 18, 2015 08:42 AM - SOCIETY FOR PERSONALITY AND SOCIAL PSYCHOLOGY, via EurekAlert
More sex may not always make you happier, according to new research published by the Society for Personality and Social Psychology.
"Although more frequent sex is associated with greater happiness, this link was no longer significant at a frequency of more than once a week," lead researcher Amy Muise said. "Our findings suggest that it's important to maintain an intimate connection with your partner, but you don't need to have sex everyday as long as you're maintaining that connection."
Some previous studies, and a plethora of articles and self-help books, have claimed that more sex equals more happiness. But this study, based on surveys of more than 30,000 Americans collected over four decades, is the first to find that association is not there after couples report having sex more than once a week on average. The study was not designed to identify the causal process, so does not tell us whether having sex up to once a week makes couples happier, or being in a happy relationship causes people to have more frequent sex (up to once a week).
Snowfall shift threatens water supply
November 18, 2015 07:17 AM - Safya Khan-Ruf, SciDevNet
Climate change-induced changes in snowfall patterns could imperil two billion people who rely on melting snow for their water supply — and developing countries must work to protect citizens from these variations, researchers say.
Another Glacier in Greenland is rapidly melting
November 17, 2015 08:26 AM - JPL NASA
It's big. It's cold. And it's melting into the world's ocean.
It's Zachariae Isstrom, the latest in a string of Greenland glaciers to undergo rapid change in our warming world. A new NASA-funded study published today in the journal Science finds that Zachariae Isstrom broke loose from a glaciologically stable position in 2012 and entered a phase of accelerated retreat. The consequences will be felt for decades to come.
The reason? Zachariae Isstrom is big. It drains ice from an area of 35,440 square miles (91,780 square kilometers). That's about 5 percent of the Greenland Ice Sheet. All by itself, it holds enough water to raise global sea level by more than 18 inches (46 centimeters) if it were to melt completely. And now it's on a crash diet, losing 5 billion tons of mass every year. All that ice is crumbling into the North Atlantic Ocean.
