If you are in the northern parts of the US (and lots of Canada) you will soon have sap running - and that means maple syrup. You probably don't think about the physiological aspects of syrup production - nor should you, that is why you have Science 2.0.

But now you can learn about the mechanisms of sap exudation—processes that trigger pressure differences causing sap to flow— while you eat your pancakes. In a paper published in the SIAM Journal on Applied Mathematics, authors Maurizio Ceseri and John Stockie propose a mathematical model for the essential physiological processes that drive sap flow. 

How is a 3-year-old better than a computer?  A pre-school child can look at a cartoon of a chicken and know that's a chicken but a computer cannot.  But things are getting better. In the International Journal of Applied Pattern Recognition, a
computer recognition system has been shown to be 99% accurate when identifying different fruits and vegetables, even the particular strain of apples or plums.

Being an overweight, lazy person is bad in lots of ways: Epidemiologists estimate that about 80 percent of the most common diseases are linked to being severely overweight and leading a sedentary lifestyle. Obese people are at an increased risk for cardiovascular diseases, vascular diseases, hypertension, diabetes and cancer. Al this lowers their life expectancy. 

Weight loss and physical activity help to counteract this. Women who lose weight lower their breast cancer risk while regular physical activity lowers the risk of developing breast, colorectal and cervical cancers. 

A University of Granada researcher has a new hypothesis concerning why bacteria seem to becoming increasingly more resistant to antibiotics.

Bacteria are incredibly versatile - they have been found in some of the most extreme conditions on the planet, and it may be just evolution in action. In this instance,  Mohammed Bakkali, a scientist in the Genetics Department at the Faculty of Science of the UGR,
 believes that bacteria that are non-resistant to antibiotics acquire resistance 'accidentally' because they take up the DNA of others that are resistant, due to the stress to which they are subjected. 

Operator storefronts and portals now account for just 6% of content downloads worldwide, with Google Play and Apple's App Store now comprising nearly 70% between them. The increasing popularity of OTT (Over The Top) stores had led to many operators closing their own mobile storefronts.
 

Fluoride is good but too much of anything can be bad. However, a filter system developed in India using a medicinal herb is very, very good.

The technology uses parts of the plant Tridax procumbens as a biocarbon filter for the ion.
