Added sugar during processing or preparing of foods remain at unhealthy levels, according to a study published by JAMA Internal Medicine.

What exactly are healthy levels? Well, there is no clear answer. Recommendations for added sugar consumption vary and there is no universally accepted threshold for unhealthy levels. For example, the Institute of Medicine recommends that added sugar make up less than 25 percent of total calories while the World Health Organization recommends less than 10 percent and the American Heart Association recommends limiting added sugars to less than 100 calories daily for women and 150 calories daily for men.

Don't count nature out yet.

Some aspects of climate change are natural. And some mitigation will be also, according to researchers from the Hebrew University of Jerusalem, Johns Hopkins University in the US and NASA’s Goddard Space Flight Center. As the globe warms, ocean temperatures rise, leading to increased water vapor escaping into the atmosphere. Water vapor is really the most important greenhouse gas and its impact on climate is amplified in the stratosphere.

Heat engines transform heat into mechanical energy with the corresponding efficiency of an Otto engine amounting to only about 25 percent, which is what your automobile gets.

The efficiency of heat engines powered by thermal heat reservoirs is determined by the second law of thermodynamics, one of the fundamental concepts in physics. It was as far back as 1824 that Frenchman Nicolas Carnot calculated the maximum possible efficiency limit of such engines, now known as the Carnot limit.

Agriculture in Finland is becoming more market driven.

What will that mean? Fluctuation in prices, more so than with current EU and Finland subsidies and quotas, but better efficiency. Competition will mean fewer farms.  The reason for the changes is because profitability continues to be poor despite strong spending by the government. The return on investment for taxpayer spending has been negative on average for the last 10 years. In 2011 in Finland, it was the third weakest in the EU, at -1.1 per cent.  The brunt of that inefficiency is small farms kept going only because of subsidies. Half of the farms in Finland produce only 5 percent of the food.

It looks more like a painting than a real-life event but this image from the Cassini orbiter shows the progress of a massive storm on Saturn. 

The head of the storm is towards the left of the image, where the most turbulent activity is shown in white, but towards the center you can also see the trace of a spinning vortex in the wake of the storm.

The image is centered at about 0º longitude and 35º N latitude and has had its colors enhanced to help reveal the complex processes in Saturn’s weather. The white corresponds to the highest cloud tops, but to the human eye the storm would appear more as a bright area against a yellow background.

Survey results analyzed by psychologists at The Fenway Institute, an advocacy group for the lesbian, gay, bisexual, and transgender (LGBT) community, found that gay and bisexual boys use anabolic-androgenic steroids (AAS) at rates much higher than their straight counterparts - almost 6X higher.
